Technical Field

The invention relates to the technical field of hardware processing equipment, in particular to a forming die ejection mechanism based on a hardware stamping part.

Background

The hardware stamping is a process for deforming or breaking plates such as stainless steel, iron, aluminum, copper and the like and special materials by using a punch press and a die to achieve a certain shape and size, the hardware stamping is sometimes called plate forming, but the difference is slight, the plate forming refers to the step of using the plates, thin-walled tubes, thin profiles and the like as raw materials, the forming method of plastic processing is generally called plate forming, at the moment, the deformation in the direction of a thick plate is generally not considered seriously, and the demoulding of a workpiece is an important link in the processing process of hardware stamping parts;

therefore, the Chinese patent discloses a simple labor-saving ejection mechanism for a hardware stamping die, which has the application number of (201720529947.0), the ejection mechanism is provided with a cam transmission mechanism to complete the ejection of a stamping piece by an ejection block, then the stamping piece is blanked, the movement of the cam mechanism is completed by driving a driving gear and a driven gear by a hand lever, the structure is simple, the operation is labor-saving, the operation is convenient, the blanking process can be rapidly completed, the operation is safe, and workers can be effectively prevented from being injured;

but this patent still has following shortcoming, all need drive driving gear and driven gear motion through manual operation hand rocker after the punching press is bent at every turn to can be ejecting with the stamping workpiece after the processing is accomplished through replacing, can't be automatic ejecting with the stamping workpiece, improved operating personnel's work load, reduced work efficiency, and the acrosome lacks guide mechanism, easily takes place the skew.

Disclosure of Invention

The invention provides a forming die ejection mechanism based on a hardware stamping part, which can effectively solve the problems that after each stamping bending, a manual operating hand rocker is required to drive a driving gear and a driven gear to move, the processed stamping part can be ejected out only by displacement, the stamping part cannot be ejected out automatically, the workload of operators is increased, the working efficiency is reduced, and the ejection body lacks a guide mechanism and is easy to deviate.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a forming die ejection mechanism based on five metals stamping workpiece, includes the mount pad, mount pad top middle part fixed mounting has the die holder, die cavity has been seted up at die holder top middle part, die cavity bottom edge fixedly connected with carriage, the bullport has been seted up on the die cavity top, sliding connection has the guide post in the bullport, the spring has been cup jointed to the guide post surface, guide post top fixedly connected with kicking block, drive capital portion fixedly connected with upper die base, upper die base bottom middle part fixedly connected with terrace die, the equal fixed mounting of upper die base bottom four corners department has the connecting block, connecting block bottom fixedly connected with stopper, the die holder top corresponds stopper bottom position department and has seted up the spacing groove.

Preferably, a rubber ring is bonded to the top end of the supporting frame, a rubber strip is bonded to the edge portion of the top end of the lower die holder, and a rubber pad is bonded to the bottom of the limiting groove.

Preferably, the edge part of the top end of the mounting seat is uniformly provided with mounting holes.

Preferably, the connecting block is fixedly connected with the upper die base through a mounting nail.

2. The rubber ring, the rubber strip and the rubber pad are arranged, the rubber ring avoids collision between the top block and the supporting frame, the rubber strip avoids collision between the lower die holder and the upper die holder, the rubber pad avoids collision between the limiting block and the bottom of the limiting groove, noise in the punching process is reduced, and the working environment of operators is optimized.

3. The connecting block, the limiting block and the limiting groove are arranged, so that the concave die cavity and the convex die of the processing equipment can be accurately positioned in the stamping process, the concave die cavity and the convex die are prevented from shifting relative positions in the matching process, the damage of a stamping part is avoided, and the processing process of the equipment is optimized.
