Description

Technical Field

[0001] The utility model belongs to the technical field of parts processing equipment, in particular to a crimping forming tool for metal parts. Background Art

[0002] After the sheet metal parts are produced, they need to be curled. Curling metal parts can reduce the exposure of the metal parts' edges, reduce the contact with oxygen and moisture, and reduce the risk of rust and corrosion on the parts' edges; curling can reduce or eliminate sharp edges and corners, reduce the risk of stabbing and cutting parts, and improve the safety of operation and use. At the same time, curling can increase the thickness and strength of the parts' edges, improve the structural strength and stability of the parts, and reduce the risk of deformation and damage to the edges.

[0003] For metal plates with large areas and regular shapes, a curling machine is usually used for uniform curling. For metal sheets with smaller areas, it is difficult for a curling machine to curl them, so they need to be curled manually using a forming tool. Existing forming tools are usually a placement table and a clamp, which is used to clamp one side of the metal sheet and then manually rolled into shape. The speed and force of manual winding are difficult to control, so there is a problem that the edge of the part is easily damaged, resulting in poor curling quality.

[0004] A rolled clamp cover is disclosed in a patent with publication number CN202508429U, which adopts the technical solution of "comprising a cover body and a cover edge, wherein the cover body and the cover edge are integrated, and the cover edge is an arc edge formed by rolling outward a straight edge cut on the periphery of the cover body. The positive effect is that the cover edge of the clamp cover is rolled outward at a certain angle from a traditional straight edge cut to an arc edge, thus becoming a rolled edge." There is a problem that a curling auxiliary device with this structure is prone to damage the edge of the part. Utility Model Content

[0028] The winding structure includes a rotating plate 17, a center rod 7, an adjusting rod 8, a driving gear 4, a driven gear 6 and a crank 5;

[0029] The rotating plate 17 is rotatably connected to the base 1, the center rod 7 is connected to the rotating plate 17, the rotating plate 17 rotates around the axis of the center rod 7, one side of the rotating plate 17 is fixedly connected to the driven gear 6, one side of the base 1 is rotatably connected to the driving gear 4, the driving gear 4 is meshed with the driven gear 6, and the crank 5 is connected to the driving gear 4; the rotating plate 17 is provided with an adjustment slot 13, the two ends of the adjustment rod 8 are movably arranged in the adjustment slot 13, and the rotating plate 17 is also provided with an adjustment member, which is used to adjust and fix the position of the adjustment rod 8. Specifically, the number of teeth of the driven gear 6 is greater than the number of teeth of the driving gear 4, that is, the driving gear 4 and the driven gear 6 constitute a speed reduction mechanism, and this design can achieve labor saving, and at the same time, this design can conveniently control the bending speed, thereby ensuring the curling effect.

[0030] Specifically, when in use, the metal sheet to be curled is placed on the base 1, and the metal sheet is moved so that one side of the metal sheet passes through the gap between the center rod 7 and the adjustment rod 8. It should be noted here that the length of the metal sheet passing through the gap is basically the length of the curling, so the curling position and curling effect of the metal sheet can be guaranteed by controlling the movement of the metal sheet. After determining the position of the metal sheet, the adjustment rod 8 is moved toward the direction close to the center rod 7 by the adjustment member until the adjustment rod 8 is about to approach the metal sheet. The position of the adjustment rod 8 is fixed by the adjustment member. Press the metal sheet by hand or press the metal sheet with other heavy objects to prevent the metal sheet from moving. Turn the crank 5 by hand, the crank 5 drives the rotating plate 17 to rotate, and the rotating plate 17 drives the adjustment rod 8 to rotate around the center rod 7 and press the metal sheet to bend to achieve curling. Due to the use of the adjustable adjustment rod 8, the gap between the adjustment rod 8 and the center rod 7 can be adapted to the metal sheet. In addition, during the bending process of the metal sheet, the adjusting rod 8 and the center rod 7 can make the metal sheet evenly stressed, thereby effectively preventing the metal sheet from being damaged during the bending process. At the same time, the crank 5 can conveniently control the rotation speed of the rotating plate 17, further improving the integrity of the metal sheet during bending, and effectively preventing the metal sheet from being damaged during the bending process.

[0031] In a preferred embodiment, a support leg 11 is fixedly connected to the bottom of the base 1, and a bottom plate 3 is fixedly connected to the bottom of the support leg 11. The support leg 11 is designed to raise the height of the base 1, so as to facilitate the installation of a rotating plate on the base 1. The bottom plate 3 at the bottom of the support leg 11 is to increase the contact area with the ground, so as to ensure the stability of the tooling structure. Further optimized, a rotating notch 9 is provided on one side of the base 1 close to the rotating plate 17, and the rotating notch 9 is used to further facilitate the installation of the rotating plate and the bending of the metal sheet.

[0032] In a preferred embodiment, a platen frame 10 is movably provided on the bottom plate 3, and a positioning wedge is provided between the bottom of the platen frame 10 and the bottom of the bottom plate 3. The platen frame 10 is used to assist in fixing the position of the metal sheet. Specifically, when in use, the platen frame 10 is pulled up by hand, and the metal sheet is placed on the base 1 and positioned. Release the platen frame 10. At this time, there is a gap between the bottom of the platen frame 10 and the bottom of the base 1, and the positioning wedge is inserted into the gap. Since the wedge is a structure with one side tilted, the platen frame 10 can stably press the metal sheet on the base 1 after the wedge is inserted.

[0033] In a preferred embodiment, the center rod 7 is detachably connected to the rotating plate 17. The design of detachably connecting the center rod 7 to the rotating plate 17 is to facilitate the replacement of the center rod 7. When the metal sheet is curled, the metal sheet will bend around the center rod 7. Therefore, it is necessary to select a suitable center rod 7 according to the metal sheets of different sizes. Specifically, the two sides of the center rod 7 can be set to a spline structure, and the center rod 7 can be quickly replaced by key connection.

[0034] In a preferred embodiment, the top of the center rod 7 is flush with the upper surface of the base 1. This design is to enable the metal sheet pushed horizontally from the base 1 to directly enter the gap between the center rod 7 and the adjustment rod 8, thereby realizing rapid alignment of the metal sheet and facilitating rapid determination of the position of the metal sheet.

[0035] In a preferred embodiment, a rotating mounting frame 16 is fixedly connected to the base 1, and a rotating plate 17 is connected to the rotating mounting frame 16, and the rotating plate 17 is rotatably connected to the base 1 through the rotating mounting frame 16. The rotating mounting frame 16 is used to facilitate the rotatable connection between the rotating plate 17 and the base 1.

Further optimized, one end of the screw rod 14 extends to the outside of the rotating plate 17 and a rotating head 15 is provided on the side where the screw rod 14 extends outside the rotating plate 17. The structure of the adjusting member adopting the screw rod 14 can facilitate the adjustment of the position of the connector 12, that is, it is convenient to change the position of the adjusting rod 8. The design of the rotating head 15 is to facilitate the manual rotation of the screw rod 14. It should also be noted that in order to ensure that the connector 12 can move in the adjusting groove 13, the connector 12 should not be able to rotate in the adjusting groove 13. Specifically, when in use, the rotating head 15 is rotated by hand to realize the rotation of the screw rod 14, and the screw rod 14 rotates to drive the connector 12 to move, and the connector 12 drives the adjusting rod 8 to move, thereby adjusting the size of the gap between the center rod 7 and the adjusting rod 8. At the same time, the screw rod 14 has the ability of self-locking. The position of the adjusting rod 8 can be conveniently fixed.
