Description

Technical Field

[0001] The utility model relates to the field of parts processing, in particular to a part anti-deviation punching device. Background Art

[0002] During the processing of parts, punching equipment is needed to open holes in fixed places. Before punching, the parts are first fixed, and then the punching machine is used to apply a certain force to the tool or mold to make the tool or mold penetrate the parts and punch out the holes. However, the surface of the parts will deform during punching, which will still affect the offset of the punching position.

[0003] After searching, the Chinese patent announcement number is CN220387618U, which discloses an anti-deviation punching device for automobile parts. The anti-deviation punching device for automobile parts drives the punch and the fixed plate downward for punching through the punching cylinder, and the set guide rod can limit the punch and the fixed plate to fall smoothly to avoid deviation. When the punch punches downward, the pressing plate first touches the surface of the part, and presses the part downward under the action of the return spring on the outside of the limit rod to avoid shaking due to deformation during stamping, and the set clamping assembly can assist in fixing it to make it more stable.

[0004] In the above patent, when the punch completes punching the parts, the internal sliding block is squeezed downward by the compression spring to prevent the waste generated by the punching from sticking to the punch and affecting the subsequent punching. However, the elastic force of the spring can only be released when the slider is completely separated from the waste. Therefore, when the punch is separated from the parts and the waste stuck in the punch is pushed out, the waste may be affected by the external environment and may be offset from the storage groove to a certain extent, and cannot fall into the storage groove smoothly.

[0026] The clamping mechanism 3 is symmetrically arranged on both sides of the pad 2, and the clamping mechanism 3 includes a vertical plate 301 bolted to the top of the workbench 1, an electric push rod 302 is fixedly connected to one side of the vertical plate 301, and a clamping plate 303 is fixedly connected to the movable end of the electric push rod 302. The clamping plate 303 is used to clamp the parts by controlling the electric push rod 302 to avoid deviation during the punching process.

[0027] A punching mechanism is provided above the pad 2, and the punching mechanism includes a mounting frame 401 bolted to the rear side of the top of the workbench 1, a hydraulic cylinder 402 is fixedly connected to the mounting frame 401, a mounting box 403 is fixedly connected to the bottom of the hydraulic cylinder 402, a punch 404 is bolted to the bottom of the mounting box 403, the inside of the punch 404 is in the shape of a hollow shell, a connecting rod 405 is slidably connected in the mounting box 403, a hammer block 406 is fixedly connected to the bottom of the connecting rod 405, and the hammer block 406 is located in the punch 404.

[0028] Auxiliary pressing mechanisms are arranged on both sides of the punching mechanism, and the auxiliary pressing mechanisms include a slide bar 501 slidably connected in the installation box 403, a pressure plate 502 is fixedly connected to the bottom of the slide bar 501, a spring 503 is connected between the top of the slide bar 501 and the inner top wall of the installation box 403, and an initial height of the pressure plate 502 is lower than the height of the punch 404, so that before punching, the pressure plate 502 first contacts with the component and presses the component, thereby further placing the component in a position to deviate when punching.

[0029] The installation box 403 is provided with a force storage mechanism 6. When punching, the force storage mechanism 6 causes the connecting rod 405 to drive the hammer block 406 to move upward and start to store force, so that after the punching is completed, the hammer block 406 can quickly impact the waste material. The force storage mechanism 6 includes a first meshing tooth 601 fixedly connected to one side of the slide bar 501, and the auxiliary pressing mechanism includes two groups of slide bars 501 symmetrically arranged on the left and right, one of which is fixedly connected to the first meshing tooth 601, and the upper part of the slide bar 501 is fixedly connected to the first meshing tooth 601.

When the punch 404 contacts the parts, the first meshing tooth 601 on the slide bar 501 meshes with the first gear 602, and the first meshing tooth 601 starts to drive the first gear 602 to rotate, and the first gear 602 meshes with the second gear 603 to drive the second gear 603 The second gear 603 is rotated, and the second meshing tooth 604 is meshed with the second meshing tooth 604, thereby driving the second meshing tooth 604 to drive the connecting rod 405 to move upward, and the connecting rod 405 drives the hammer block 406 to move upward. When the punch 404 reaches the bottom of the component, the first meshing tooth 601 on the slide bar 501 is separated from the first gear 602, and the first gear 602 is reversed under the action of the torsion spring, so that the second gear 603 pushes the second meshing tooth 604 downward, and the second meshing tooth 604 drives the connecting rod 405 to move downward, and the connecting rod 405 drives the hammer block 406 to impact downward quickly, hammering the waste into the collection box 201, avoiding the punch 404 from separating from the workpiece and then pushing out the waste, thereby causing the waste to be affected by the external environment and deviate, and cannot fall accurately into the storage groove.
