Technical Field

The invention relates to the field of industrial design engineering, in particular to a model making tool for industrial design.

Background

In the field of industrial design, model making is a more central and critical process. The modeling generally includes 3D printing, carpentry, porcelain manufacturing, and the like. And porcelain preparation generally adopts and fires after the hand shaping, when firing, need fire through the high temperature of 1280 degrees in that ceramic kiln is inside, for the blank can the thermally equivalent, especially to some components like spherical structure, directly adopt the support to place the mode can lead to the partial position of blank effectively to be heated, consequently need adopt the mode of hanging to fire. Tungsten metal has a high melting point and is therefore widely used in the field of precision ceramic firing. In the firing process, a metal tungsten wire is used for penetrating into the center of the ceramic ornament, two ends of the metal tungsten wire are suspended between the two fulcrum frameworks, and then the ceramic ornament is fired at high temperature. After firing, the tungsten wire is softened and deformed to a certain extent due to the influence of high temperature, and when the tungsten wire penetrates into the ceramic ornament blank again, the straightness of the tungsten wire cannot meet the requirement of reuse. Because the sizes and weights of various workpieces are different, the workpieces have the tendency of sliding towards the position between the two supporting points under the action of gravity, so that the fired tungsten wire is approximately in an arc-shaped structure, and because the stress points of different workpieces are different, bending deformation with smaller diameter can be formed in a small range.

In the prior art, a manual straightening mode is generally adopted, or a tungsten wire is heated and then placed between two plate-shaped tools for repeated rolling. However, the manual knocking mode is time-consuming and labor-consuming, and the forming effect is poor. And adopt the mode that the platelike instrument rolled to press also can consume a large amount of time, to the less bending deformation department of some diameters, because the existence of arc portion, when carrying out one-way rolling, the arc becomes straight gradually, but during the return stroke rolling, because the route is opposite, the easy reverse deformation of tungsten filament, so reciprocal easy lead to the fact tungsten filament fatigue strength to reduce, the frequent atress of inflection point can cause tungsten filament life to reduce and even break off when firing and make the product scrap.

In specific work, as shown in fig. 2 and 3, the driving motor 20 rotates to drive the power wheel 23 to rotate, when the power wheel 23 rotates, the guiding position-limiting plate 222 is driven to move by the matching of the driving groove and the power rod 223, the guiding position-limiting plate 222 is fixedly arranged on the guiding support 22, so the power wheel 23 finally drives the guiding support 22 to move, taking the state shown in fig. 2 as an example, at this time, taking the counterclockwise rotation of the power wheel 23 as an example, the driving groove drives the power rod 223 to move, at this time, the guiding support 22 has a tendency of moving to the right under stress, the guiding support 22 applies force to the driving frame 21, the driving frame 21 slides to the right on the base 10, the guiding support 22 moves to the right, the arc-shaped position-limiting plate 221 and the guiding position-limiting plate 222 both move to the auxiliary rod 231 and the guiding support 22 relatively, the auxiliary rod 231 gradually enters the guiding sliding groove formed by the arc-shaped position-limiting plate and the guiding position-limiting plate 222, and the guiding sliding groove is also in an arc shape, and in the process, the power wheel 23 is continuously meshed with the power rod 223 and applies force to the power rod 223, so that the power wheel 23 can force the guide limit plate 222 to finally cause the guide support 22 to move in an arc-shaped track of a guide chute on the left side when the power wheel 23 rotates, the guide support 22 continuously moves upwards in the process that the guide limit plate 222 moves to the upper side of the auxiliary rod 231, and meanwhile, the guide support 22 moves leftwards and leftwards first, and because the height of the limit groove is greater than that of the guide support 22, the guide support 22 can slide upwards, and after the power rod 223 is completely positioned above the auxiliary rod 231, the power wheel 23 continuously rotates to drive the power rod 223 to move leftwards and force the whole guide support 22 to move leftwards. The working process after the power wheel 23 moves to the right end of the guide limit plate 222 is similar to the above process, and only the direction is opposite, so that the detailed description is omitted. Therefore, in the whole process, along with the rotation of the power wheel 23, the guide support 22 is forced to move in a substantially square track (when moving to both ends, the guide support moves in an arc track, but the whole guide support moves in a substantially square shape), and the support seat 30 is finally driven to move in a substantially square track because the support seat 30 is fixedly arranged on the guide support 22.

Example two:

in the first embodiment, because two ends of the tungsten wire are fixed during firing and the workpiece is inserted into the tungsten wire, the workpiece has a tendency of moving to a midpoint position of the two ends under the action of gravity, so that the tungsten wire is finally stressed and deformed into an arc-shaped structure, and when the arc-shaped structure is rolled, the tungsten wire is integrally and synchronously stressed but is extruded and deformed due to inconsistent structural forms, so that the tungsten wire can be extruded and expanded to two sides by means of the stress of the tungsten wire and finally tends to be linear, and the process completely depends on the extrusion of the material, so that the tungsten wire is subjected to large stress and deformation in the process, so that the effective service life is greatly reduced and the efficiency is low, in the first embodiment, as shown in fig. 1 and 4 to 7, the tungsten wire bending machine further comprises an extending device which comprises a lead screw 44, a sliding plate 41, a return spring 45, two guide rods 43 and two stretching blocks 42; as shown in fig. 4, two guide rods 43 are fixedly arranged on the pressing block 40, and two ends of each guide rod are penetrated to the outer side of the pressing block 40, two stretching blocks 42 are respectively positioned on two sides of the pressing block 40 and are arranged on the guide rods 43 in a sliding manner, wherein sliding holes matched with the guide rods 43 are formed in the stretching blocks 42, and the guide rods 43 are arranged in the sliding holes in a sliding manner; the screw rods 44 are rotatably arranged on the pressing block 40, two ends of each screw rod penetrate through the outer side of the pressing block 40, threaded holes matched with the screw rods 44 are formed in the two stretching blocks 42, and the screw rods 44 are matched with the threaded holes; the sliding plate 41 is slidably disposed at the lower side of the pressing block 40, as shown in fig. 7, a sliding slot is formed on the pressing block 40, a sliding block 412 is disposed on the sliding plate 41, the sliding block 412 is slidably disposed in the sliding slot, as shown in fig. 5, a driving rack 411 is formed on the sliding plate 41, a driving gear 441 is disposed at a position of the screw rod 44 corresponding to the driving rack 411, and the driving gear 441 is engaged with the driving rack 411; the return spring 45 has one end connected to the pressing block 40 and the other end connected to the slide plate 41.

When the tungsten filament drawing device works, a tungsten filament is placed on the supporting seat 30, the arc center of the tungsten filament is approximately positioned at the center of the sliding plate 41, two ends of the tungsten filament are approximately and respectively positioned below the two drawing blocks 42, the direction of the arc bulge is opposite to the moving direction when the supporting seat 30 is extruded (the displacement generated in the arc middle part of the tungsten filament is larger than the displacement of the two ends and the two ends of the tungsten filament are drawn towards two sides in the working process), the driving device drives the supporting seat 30 to move, the tungsten filament is driven to move upwards to one side in the moving process of the supporting seat 30, the sliding plate 41 slides under the force after the tungsten filament is abutted against the sliding plate 41, and the pressing block 40 cannot move fixedly, so that the sliding plate 41 and the pressing block 40 can move relatively, the driving gear 441 is driven to rotate by the rack 411 when the sliding plate 41 moves, the driving gear 441 drives the screw rod 44 to rotate, the screw rod 44 forces the drawing blocks 42 to move towards two sides through the matching effect of the threaded holes on the drawing blocks 42, when the stretching block 42 moves, force is applied to two ends of the tungsten wire, so that the tungsten wire is subjected to stretching force towards two sides, the tungsten wire can be straightened without being simply extruded, more tungsten wires are pulled towards two sides, and the tungsten wire straightening device also accords with the change characteristic of the tungsten wire in the using process. The tungsten wire is not extended simply by extrusion through the stretching of the stretching block 42, so that the reduction of fatigue strength caused by frequent extrusion is avoided, and the service life is shortened.

Example three:

because the tungsten filament is when the narrow-range atress, produce the less deformation of radian easily, and little radian warp can directly produce the propelling movement and be difficult for producing the upset at the relative motion in-process of supporting seat 30 and briquetting 40, lead to the unable effective alignment of little radian department of deformation, consequently still include elastic seat 31 and lifting spring 32 in this embodiment, seted up on the supporting seat 30 and accomodate the groove, elastic seat 31 can set up in accomodating the inslot with sliding from top to bottom, lifting spring 32's both ends are connected to elastic seat 31 and supporting seat 30 respectively.

The during operation, the tungsten filament is placed on elastic seat 31, and when little radian department of deformation atress, elastic seat 31 atress moved down, for little radian department of deformation formation hold its deformation space of upset to make the tungsten filament can effectual upset, thereby make little radian deformation be in the rolling process that overturns and press the in-process and can progressively straighten.

Example four:

in this embodiment, as shown in fig. 10, the guiding slot 311 is formed in the elastic seat 31, the cross section of the guiding slot 311 is C-shaped and the first side is vertically disposed, because the moving direction of the elastic seat 31 is single and the small arc deformation direction of the tungsten filament is random in the extrusion state (i.e., the auxiliary rod 231 is located below the power rod 223, the upper end of the guiding seat 22 is closely attached to the upper end of the driving slot, and the guiding seat 22 is located at the highest position in the whole movement process), when the protruding direction of the small arc deformation of the tungsten filament is the same as the moving direction of the elastic seat 31, the elastic seat 31 is easy to turn over the tungsten filament to straighten the small arc deformation, but when the protruding direction of the small arc deformation of the tungsten filament is opposite to the moving direction of the elastic seat 31, the tungsten filament is difficult to turn over, so that the partial deformation cannot be straightened all the time, the guiding slot 311 is formed in the elastic seat 31, and the cross section of the guiding slot 311 is C-shaped and the first side is vertically disposed, The other opposite second side surface is obliquely arranged towards the direction far away from the first side surface, and the oblique direction is the same as the moving direction of the elastic seat 31 in the extrusion state, wherein the depth of the guide groove 311 is slightly smaller than the diameter of the tungsten wire, and the width of the guide groove 311 is slightly larger than the diameter of the tungsten wire.

During operation, the tungsten wire will fall into the guiding groove 311 (even if the tungsten wire does not fall into the guiding groove 311 along with the pushing of the elastic seat 31, the tungsten wire will slide into the guiding groove 311), and the small arc deformation part will protrude out of the guiding groove 311, so that the part is located on the upper side of the guiding groove 311, when the protruding direction of the part of the small arc deformation part is the same as the moving direction of the elastic seat 31 (at this moment, the part may be opposite), along with the joint extrusion of the elastic seat 31 and the sliding plate 41, the part of the small arc deformation part with the same protruding direction as the moving direction of the elastic seat 31 is straightened, and after the straightening, the part will fall into the guiding groove 311, and because one side of the guiding groove 311 is inclined vertically, the tungsten wire will fall towards the inclined side under the action of gravity, thereby realizing the turning of the protruding direction, so that the protruding direction of the small arc deformation part which is not straightened yet becomes the same as the moving direction of the elastic seat 31, thereby achieving alignment.

The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the above embodiments, and any variations that can be made by those skilled in the art are intended to fall within the scope of the present invention.
