Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to fig. 1 to 7 in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

(as shown in fig. 1, fig. 2, fig. 3 and fig. 4) is a radial rotary conveying mechanism of a moving table of a press for forging and producing the special-shaped steel rail, which is hereinafter referred to as: the radial rotary conveying mechanism 4 is a specific application embodiment.

Application example 1 of the present invention: see fig. 1 and 2

On the basis of a press machine 1; press station rails 2 are arranged below the press 1, and one press station rail 2 is a conventional press station rail. A press machine station rail 2 and three platform station rail 3 that move use radial rotary conveying mechanism 4 as the cross center respectively, and a press machine station rail 2 and a plurality of platform station rail 3 that move are located four normal position orientations of radial rotary conveying mechanism 4 east west south north respectively and set up, and a cross rail structure is constituteed with a plurality of platform station rail 3 to a press machine station rail 2, and a cross rail structure is finally refuted with press machine station rail 2. The three platform moving station rails 3 are respectively provided with a platform moving 5; the moving platforms 5 are respectively used for installing different types of forging and pressing die tools. Each moving platform 5 is provided with an independent moving mechanism, a jacking mechanism and a descending mechanism, and the moving mechanism, the jacking mechanism and the descending mechanism are in an industry universal mode so as to meet the use requirements of the press machine.

This example, when used: as shown in fig. 1, when the moving platform 5 on the opposite moving platform station rail 3 of the press machine 1 needs to be fed into the press machine station rail 2, the radial rotary conveying mechanism 4 drives the common rail 44 thereon to rotate by 90 ° to the horizontal and transverse state shown in fig. 1, so that the moving platform 5 on the opposite moving platform station rail 3 of the press machine 1 can enter and exit the press machine station rail 2. When any one of the moving platforms 5 on the upper side and the lower side of the press machine 1 needs to be fed into the press machine station rail 2, in the state shown in fig. 1, the radial rotary conveying mechanism 4 firstly drives the common rail 44 thereon to rotate clockwise or anticlockwise by 90 degrees to the longitudinal rail butt joint state shown in fig. 2: then any one of the moving platforms 5 on the upper side and the lower side of the press machine 1 moves to the central position of the radial rotary conveying mechanism 4, the radial rotary conveying mechanism 4 drives the moving platform 5 which is in place thereon to rotate reversely by 90 degrees and restore to the butt joint state of the transverse rail as shown in figure 1, and then the moving platform 5 moves to the press machine station rail 2 from the radial rotary conveying mechanism 4 to finish the conveying of the lateral moving platform 5.

Application example 2 of the present invention: see FIG. 3

Five sets of moving platforms 5 are matched with one press machine 1, namely, one press machine station rail 2 and five moving platform station rails 3 form an embodiment of two cross rail structures. This example, when used: as shown in fig. 3, a station moving rail 3 is needed to be shared at the convergence of the two cross-shaped rail structures, that is, the station moving rail 3 at the intersection of the inner sides of the two cross-shaped rail structures connects the two cross-shaped rail structures to communicate with the station rail 2 of the press. In the state shown in the figure, the conveying of any one of the moving platforms 5 towards the press station rail 2 on the moving platform station rails 3 at the non-intersection positions of the two cross rail structures located at the outer branches can be realized. Taking as an example the transfer station 5 furthest to the right as shown in fig. 3, is transported towards the press station rail 2: the right cross-shaped rail structure rotates 90 degrees anticlockwise or clockwise from the state shown in fig. 3, so that the right cross-shaped rail structure is transversely connected, then the moving platform 5 at the farthest right side moves to the center of the radial rotary conveying mechanism 4 of the right cross-shaped rail structure in the two cross-shaped rail structures, the moving platform 5 continues to move forwards until the moving platform 5 moves to the center of the radial rotary conveying mechanism 4 of the left cross-shaped rail structure and stops, the radial rotary conveying mechanism 4 at the left side drives the moving platform 5 to rotate 90 degrees radially, so that the left rail transverse butt joint state is switched to the left rail longitudinal butt joint state, then the moving platform 5 moves upwards to the press station rail 2 along the radial rotary conveying mechanism 4 which is longitudinally opened at the left side, and the conveying of the moving platform 5 at the farthest right side to the press station rail 2 shown in fig. 3 is completed. By analogy, the transport of the upper table 5 in any of the five directions towards the press station rails 2 of the embodiment of fig. 3 can be realized.

Wherein, different platform 5 that moves can install multiplex displacement platform mould frock, thick pier tooling, heel end die mould frock, ordinary heel end die mould frock, extension heel end die mould frock etc. respectively.

The radial rotary conveying mechanism 4 is arranged at the cross position, and when the multiple moving platforms 5 enter and exit the press station rail 2, the radial rotary conveying mechanism 4 is used for realizing the on-off, connection and conversion of the different moving platforms 5 entering the rail, thereby simplifying the design problem of the multiple moving platform rail system to the maximum extent. The structure of the multiple moving platforms 5 configured by the press machine 1 can thoroughly get rid of the limitation of the auxiliary lifting and moving application quantity of the overhead travelling crane in the workshop space, can expand the application of configuring at least three sets of moving platforms 5 on a single press machine 1, and has important significance for improving the application level of industrial equipment and promoting the progress of the turnout machining process.

In the design time: on one hand, the radial rotary conveying mechanism 4 is required to ensure the safety and stable conveying of the bearing state of the die tool on the large-tonnage moving platform 5; on the other hand, the butting control precision of different moving platforms 5 for entering and exiting different rails is ensured, so that the large-tonnage moving platform can stably move in a mould loading state without slipping, clamping and static, tooth breaking, rod breaking, motor overload and the like. To achieve the above functions, reference is made specifically to the following structural improvements of the present invention:

the radial rotary conveying mechanism (shown in fig. 5 in conjunction with fig. 4) that is briefly described, of the moving table of the press for forging and producing the special-shaped steel rail, includes a servo motor 41, a radial horizontal rotation speed reduction transmission mechanism 42, a rail bearing mounting base 43, and a common rail 44.

Wherein, the upper end surface of the rail bearing mounting base 43 is fixedly welded with public rails 44 which are parallel at intervals; the parallel spacing of the common rails 44 is equal to the parallel spacing of the rails of the press station rails 2 and the transfer station rails 3, so as to accurately engage and adapt to the press station rails 2 and the transfer station rails 3 (as shown in fig. 1, 2 and 3). A servo motor 41 (combined with fig. 6) is fixedly arranged on the lower end surface of the rail bearing mounting base 43; the power output end of the servo motor 41 is connected with the power input end of the radial horizontal rotation speed reduction transmission mechanism 42, and the power output end of the radial horizontal rotation speed reduction transmission mechanism 42 drives the rail bearing mounting base 43 to rotate horizontally. Namely, the servo motor 41 drives the track bearing mounting base 43 to rotate in the fixed-axis radial direction through the radial horizontal rotation speed reduction transmission mechanism 42. Specifically, the radial horizontal rotation reduction transmission mechanism 42 includes a reduction gear, a bevel gear transmission mechanism, or a non-bevel gear transmission mechanism. The power output end of the servo motor 41 is connected with the power input end of the speed reducer, the power output end of the speed reducer is coaxially and fixedly connected with a transmission shaft, and the transmission shaft is rotatably supported and installed at the bottom of the rail bearing installation base 43 through a shaft seat and a bearing piece in the shaft seat; the servo motor 41 drives the transmission shaft to rotate at a low speed, the transmission shaft is coaxially and fixedly provided with a bevel gear or a gear of a bevel gear transmission mechanism or a non-bevel gear transmission mechanism, and the bevel gear or the gear is meshed with a radial rack, so that the servo motor drives and drives the track bearing mounting base 43 to rotate radially.

The invention adopts the servo motor 41 to drive and the radial horizontal rotation speed reduction transmission mechanism 42 to reduce the speed to realize the horizontal rotation of the track bearing mounting base 43, can realize the controllability of the radial rotary conveying mechanism 4 to control the rotation of the moving platform with high precision, can control the rotation precision of the radial rotary conveying mechanism 4 within +/-0.5 degrees, has the signal delay less than 10mS, and has accurate and reliable control.

In the above embodiment, further: the radial horizontal rotation speed reduction transmission mechanism 42 is composed of a shaft seat 421, a transmission shaft 422, a worm gear and worm transmission mechanism 423, a bevel gear 424 and a radial bevel rack 425.

Wherein, the transmission shaft 422 is rotatably supported and installed at the bottom of the rail bearing installation base 43 through the shaft seat 421 and the bearing member in the shaft seat 421; the transmission shaft 422 is driven by the servo motor 41, and the worm gear 423 drives the transmission shaft 422 to rotate in a speed reduction way. Specifically, the method comprises the following steps: the power output shaft of the servo motor 41 is coaxially and fixedly connected with a worm in a worm and gear transmission mechanism 423, the worm is meshed with a worm wheel, the worm wheel and the transmission shaft 422 are coaxially and fixedly connected into a whole, the worm and gear transmission mechanism 423 realizes a speed reduction function and a self-locking function after the transmission shaft 422 stops rotating after the servo motor stops operating. On this basis, the shaft 422 is provided with a bevel gear 424 at the axial end, and the bevel gear 424 is engaged with a radial bevel rack 425 of an annular structure below the track bearing mounting base 43 so as to drive the track bearing mounting base 43 to rotate horizontally and radially. The radial umbrella rack 425 is a ring-shaped umbrella tooth structure. The scheme adopts the bevel gear 424 to engage with the radial bevel rack 425, has a centripetal transmission function, and ensures that the radial rotary conveying mechanism 4 can stably rotate and operate by self-centering.

Moreover, the invention reduces the speed through the worm gear drive 423, the bevel gear 424 is meshed with the radial bevel rack 425 to realize the horizontal rotation of the track bearing mounting base 43, and the worm gear drive 423 can realize the speed reduction function of the transmission shaft 422 and has a self-locking function compared with a speed reducer or a reduction gearbox, so that the position of the radial rotary conveying mechanism 4 after high-precision spin-stop is naturally locked, and the deviation and the dislocation of the position of the connected track after successful butt joint are effectively prevented.

In the above embodiment, further: in order to ensure the bearing stability of the radial rotary conveying mechanism 4 in the horizontal centering and rotating process: the two transmission shafts 422 are crossed and rotatably supported and installed at the bottom space of the rail bearing installation base 43. By adopting the structure of two transmission shafts 422 crossed in a cross way, compared with the structure improvement after one transmission shaft 422 is combined, the power transmission can be realized uniformly and stably, and the bumping problem when the track bearing mounting base 43 rotates is avoided.

In the above embodiment, further: the shaft seat 421 is cylindrical; the shaft seat 421 is concentrically and vertically fixedly installed at the bottom of the rail bearing installation base 43; furthermore, the following steps are carried out: the axle seat 421 with a cylindrical shape also provides a centering function for the horizontal radial rotation of the track bearing mounting base 43. Specifically, the method comprises the following steps: and a bearing element is arranged in the seat body of the shaft seat 421, and the bearing element supports the middle part of the shaft body of the transmission shaft 422 so as to realize that the transmission shaft 422 takes the shaft seat 421 as the center and realize the rotating supporting installation of the transmission shaft 422 in the shaft seat 421.

On this basis, the bottom end of the shaft seat 421 with a cylindrical shape is used for concentrically rotating and adapting to the center of the base structure (not shown in the base structure diagram), and the base structure provides concentric guidance for the horizontal radial rotation of the track bearing mounting base 43, so that the track bearing mounting base 43 can be centered and stably rotated. Therefore, the shaft seat 421 with a cylindrical shape cooperates with the gear 424 and the radial bevel rack 425 to effectively promote the self-centering rotation of the radial rotary conveying mechanism 4, thereby ensuring the rotation stability of the radial rotary conveying mechanism 4.

(as shown in fig. 6) on this basis: the two servo motors 41 respectively drive each transmission shaft 422 to rotate from the middle of each transmission shaft 422 through a worm gear mechanism 423. That is, the power output shaft of each servo motor 41 is coaxially and fixedly connected with the worm in the worm and gear transmission mechanism 423, the worm is engaged with the worm wheel, and the worm wheel is coaxially and fixedly connected with the shaft body of the transmission shaft 422 into a whole. Two space vertical transmission shafts 422 are coaxially and fixedly provided with bevel gears 424 at two ends of the outer shaft end respectively; the four bevel gears 424 are respectively meshed with the radial bevel gear rack 425 from four radially and uniformly distributed points at the same time so as to drive the track bearing mounting base 43 to horizontally and radially prevent bumping and rotating.

Therefore, the two transmission shafts 422 of the invention are respectively installed in the cross-shaped rotation support at the bottom space of the track bearing installation base 43, and the bevel gears 424 are respectively and fixedly installed coaxially at the two ends of the outer shaft end of each transmission shaft 422; thus, a total of four bevel gears 424 respectively engage the radial bevel rack 425 from four radially spaced points simultaneously to effect horizontal radial rotation of the track load bearing mounting base 43. Compared with a bevel gear transmission structure design, four-point uniform distribution support transmission enables the horizontal rotation of the track bearing weight mounting base 43 in the radial rotary conveying mechanism 4 to run more stably, and the bumping problem is avoided.

In the above embodiment, further: because move platform 5 after installing the mould frock additional, weight is above the tonnage level basically, consequently, for satisfying large-tonnage bearing capacity demand, radial rotary conveying mechanism 4 still improves as follows when designing: namely, a plurality of load wheel groups 45 are respectively arranged on the transmission shafts 422; in the preferred embodiment shown in the figures, four load-bearing wheel sets 45 are respectively disposed on the two transmission shafts 422, the four load-bearing wheel sets 45 are uniformly distributed on each transmission shaft 422, the eight load-bearing wheel sets 45 are formed in total, and the eight load-bearing wheel sets 45 respectively share the weight of the load-bearing rail mounting base 43, so as to meet the requirement of the heavy load of the rail load-bearing mounting base 43. So that the aforementioned bevel gear 424 does not bear the weight of the base, the bevel gear 424 merely provides a centripetally engaging power transmitting guide for rotation of the track load bearing mounting base 43. The bevel gear 424 is prevented from bearing the weight force, i.e. the primary drive member bevel gear 424 is prevented from being damaged. The long-time, long-life, more durable steady operation of drive mechanism is guaranteed.

Therefore, the transmission shafts 422 crossed in the cross shape are respectively provided with a plurality of load wheel groups 45; the plurality of load bearing wheel sets 45 share the weight of the bearing rail bearing mounting base 43, and the bevel gear 424 only provides centripetal meshing power transmission guidance for the rotation of the bearing rail mounting base 43; the problem of how radial rotary conveying mechanism 4 bears tonnage level weight and moves platform and move mould frock on the platform is solved, main drive member is effectively protected not to receive the damage, and extension equipment life for when radial rotary conveying mechanism 4 bears large-tonnage level and moves platform rotary motion, bear more stably, safely, reliable.
