Detailed Description

As shown in fig. 2 to 4, the tensioning and feeding device for processing the teeth on the surface of the hollow profile comprises an automatic clamping and feeding device S for clamping a bottom plate of the cavity of the profile and feeding the profile, wherein the automatic clamping and feeding device S is connected with a tensioning and positioning device K of the cavity of the profile below the hobbing mechanism R.

The section bar cavity tensioning and positioning device K comprises a first tensioning rod and a second tensioning rod which are arranged in pairs in a fixing frame, each pair of the first tensioning rod and the second tensioning rod is connected through a width adjusting mechanism, the end part of the first tensioning rod is connected with the fixing frame through a transverse adjusting mechanism, and the end part of the second tensioning rod is connected with the other end of the fixing frame through a longitudinal adjusting mechanism. The roller tooth type roller tooth tensioning device is suitable for tensioning and fixing sectional materials with cavity structures such as H-shaped channel steel and the like, and is favorable for being matched with a gear hobbing mechanism to roll uniform and consistent teeth on the surface of a flanging of a cavity of the sectional material.

Specifically, as shown in fig. 8 to 12, a fixing frame is mounted on the bottom plate M, and the fixing frame includes a fixed barrier K1.1 and a movable barrier K1.2 driven by the pressing cylinder Q, and the fixed barrier K1.1 and the movable barrier K1.2 are connected through a front barrier K1.3 located at the head and a rear barrier K1.4 located at the tail, wherein the front barrier K1.3 is located above the fixed barrier K1.1 and the movable barrier K1.2, the rear barrier K1.4 is U-shaped, and two U-shaped double arms are connected with a rotating shaft K1.5.

Three pairs of first tension rods K2.1 and second tension rods K2.2 are arranged in the fixing frame side by side, each pair of the first tension rods K2.1 and the second tension rods K2.2 are parallel to each other, the overlapped parts of the first tension rods K2.1 and the second tension rods K2.2 are connected with a plurality of connecting rods K3 arranged side by side, and two ends of each connecting rod K3 are hinged with the first tension rods K2.1 and the second tension rods K2.2 respectively. When the angle that connecting rod K3 was located changes, can adjust the interval of first tight pole K2.1 and the second tight pole K2.2 that rises.

The first tensioning rods K2.1 all extend towards the front stop strip K1.3, three transverse long holes K4.1 are correspondingly formed in the front stop strip K1.3, and each first tensioning rod K2.1 is connected with the front stop strip K1.3 through a guide bolt K4.2 penetrating into the transverse long hole K4.1. When the distance between the first tension rod K2.1 and the second tension rod K2.2 is changed, the first tension rod K2.1 can drive the guide bolt K4.2 to make a transverse movement in the transverse long hole K4.1.

The second tensioning rods K2.2 extend towards the direction of the rear barrier strip K1.4, three pawls K5.1 are correspondingly mounted on a rotating shaft K1.5 which is positioned above the second tensioning rod K2.2 in an inclined manner, the bottoms of the pawls K5.1 are circular rotating surfaces which are in contact with the upper surface of the middle connecting section of the U-shaped rear barrier strip K1.4, and the upper parts of the circular rotating surfaces are hinged with the end parts of the second tensioning rods K2.2 through inclined pull rods K5.2; the inside of the claw opening of the pawl K5.1 is connected with a lifting pressure plate K5.4 driven by a first cylinder K5.3 in a clamping manner, and the first cylinder K5.3 is arranged on a bracket positioned at the rear side of the rear barrier strip K1.4. When the first cylinder K5.3 presses down the lifting plate K5.4, the pawl K5.1 rotates, so that the diagonal draw bar K5.2 drives the second tension rod K2.2 to move to the rear side, even if the second tension rod K2.2 moves longitudinally.

Generally, a hobbing mechanism R is installed above the bottom plate M corresponding to the overlapping area of the first tension bar K2.1 and the second tension bar K2.2. When the device is used, the upper cavities of the three H-shaped channel steel are respectively aligned with each pair of tension rods and inserted into a preset position (see fig. 12) from the rear part of the fixing frame, then the first cylinder K5.3 presses down the lifting plate K5.4, the second tension rod K2.2 longitudinally moves towards the rear part of the fixing frame, the connecting rod K3 is pulled to rotate, the inclined state (see fig. 9) is changed into a state perpendicular to the tension rods (see fig. 11), in the process, the first tension rod K2.1 gradually leaves away from the second tension rod K2.2, and the guide bolt K4.2 is driven to transversely move towards one side of the fixed stop strip K1.1 along the transverse long hole K4.1. Along with the expansion of the distance between the first tensioning rod K2.1 and the second tensioning rod K2.2, the first tensioning rod K2.1 and the second tensioning rod K2.2 are gradually close to two side walls of the upper cavity of the H-shaped channel steel to form a cavity tensioning state. At the moment, the H-shaped channel steel is firmly clamped, so that the upper hobbing mechanism is very favorable for processing uniform and consistent teeth on the upper surface of the cavity flanging of the upper hobbing mechanism.

As shown in fig. 5, the automatic clamping and feeding device S includes a base S1.1, a pair of guide rails S1.2 arranged along a length direction are mounted on the base S1.1, and a moving platform S2 is slidably mounted on the guide rails S1.2; the moving platform S2 is provided with a helical gear S1.4 driven by a feeding motor S1.3, the helical gear S1.4 is positioned below the moving platform S2 and is meshed with a helical rack S1.5 arranged on the left side surface of the base S1.1. When the feeding motor S1.3 is started, the helical gear S1.4 and the helical rack S1.5 are matched with each other, and the moving platform S2 is driven to move along the guide rail S1.2. The right side surface of the base S1.1 is provided with a crawler belt for installing electric wires, signal wires and the like.

The moving platform S2 is provided with a clamping mechanism for clamping hollow cavity profiles such as H-shaped channel steel. As shown in fig. 6, the clamping mechanism includes a second cylinder S2.1 mounted on the moving platform S2, a piston rod of the second cylinder moves along the length direction of the base S1.1, and three rolling bearings S2.2 arranged side by side are mounted at the tail end of the piston rod; three fixing splints S2.3 extending outwards are mounted on the bottom surface of the mobile platform S2, and each fixing splint S2.3 corresponds to one rolling bearing S2.2; each fixed clamping plate S2.3 is provided with a V-shaped rotating plate S2.5 connected through a hinge shaft S2.4, the hinge shaft S2.4 is positioned at the bending part of the V-shaped rotating plate S2.5, and two sides of the hinge shaft S2.4 are respectively provided with a driving cavity for clamping the rolling bearing S2.2 and a clamping cavity for clamping the bottom plate of the H-shaped channel steel cavity. In order to firmly clamp the section, clamping teeth with strong clamping force are arranged on one sides of the clamping cavities of the fixed clamping plate S2.3 and the V-shaped rotating plate S2.5.

Since the clamping cavity is clamped at one end of the section bar, in order to enable the section bar to smoothly move along with the moving platform S2, a roller mechanism S3 is further installed on the base S1.1. The roller mechanism S3 includes a plurality of spaced supports, each of which is provided with a roller at the bottom of the profile for supporting the profile.

Taking the H-shaped channel steel in fig. 5 as an example, when it needs to be clamped, it is first placed on the roller mechanism S3, and then the cavity bottom plate is dragged into the clamping cavity formed by the fixed clamping plate S2.3 and the V-shaped rotating plate S2.5, and then the second cylinder S2.1 is started, the rolling bearing S2.2 moves toward the driving cavity, so that the V-shaped rotating plate S2.5 on one side of the driving cavity moves upward, and the V-shaped rotating plate S2.5 on one side of the clamping cavity rotates downward around the hinge shaft S2.4 along with it, and cooperates with the fixed clamping plate S2.3, and the cavity bottom plate located in the middle of the H-shaped channel steel is firmly clamped (see fig. 7). After the hobbing mechanism matched with the H-shaped channel steel finishes rolling a section of teeth on the surface of the cavity flanging of the H-shaped channel steel, the feeding motor S1.3 is started, so that the moving platform S2 drives the H-shaped channel steel to move forwards for a certain distance, and the hobbing mechanism is convenient for rolling the next section of teeth.

When the automatic clamping and feeding device is used, the upper cavity of the H-shaped channel steel is inserted between each pair of the first tensioning rod K2.1 and the second tensioning rod K2.2 from one side of the pawl K5.1 in the profile cavity tensioning and positioning device K, and the cavity bottom plate in the middle of the H-shaped channel steel is pushed into the clamping cavity in the automatic clamping and feeding device S. Starting a second cylinder S2.1 to enable the H-shaped channel steel to firmly clamp a cavity bottom plate of the H-shaped channel steel, and starting a first cylinder K5.3 to enable the distance between a first tensioning rod K2.1 and a second tensioning rod K2.2 to be enlarged to form firm tensioning on the side wall of an upper cavity of the H-shaped channel steel; then, the hobbing mechanism R positioned above the profile cavity tensioning and positioning device K starts to work, and teeth rolling is carried out on the cavity flanging surface of the H-shaped channel steel at the lower part of the hobbing mechanism R; after the section of tooth is rolled, the first cylinder K5.3 is reset, the tensioning of the upper cavity side wall of the H-shaped channel steel is cancelled, then the feeding motor S1.3 is started, the area of the next section of tooth to be processed is moved to the position below the hobbing mechanism R, then the upper cavity side wall of the H-shaped channel steel is tensioned again according to the method, and the cavity flanging surface of the H-shaped channel steel is subjected to tooth rolling. And repeating the steps until all the teeth are rolled.
