Automobile front damper installation plate blanking die

Abstract

The invention discloses an automobile front damper installation plate blanking die, which comprises an upper die body and a lower die body, wherein the upper die body is provided with an upper die cut die, a punching head and a material presser; the lower die body is provided with a lower die opposite to the material presser up and down and used for supporting a workpiece so as to be matched with the upper die cutting die and the punching head to perform edge cutting and punching in the workpiece; a blank holder is arranged at the periphery of the lower die; the lower die body is further provided with a cam type material jacking device; and the cam type material jacking device can generate a material jacking displacement so as to jack the a material jacking plate. With the adoption of the automobile front damper installation plate blanking die, the workpiece can be compressed and positioned effectively during a machining process; the workpiece is prevented from transformation; the machining quality is good; a cut edge and a punched hole of the workpiece are finished through once machining; the product quality and the machining efficiency are improved; the production cost is reduced; certain material jacking displacement can be generated; the workpiece can be jacked out effectively without material clamping phenomena; the stable operation of continuous production can be ensured; and the production efficiency can be improved.

Description

Technical field [0001] The invention relates to a machining die, in particular to a blanking die for an automobile front shock absorber mounting plate. Background technique [0002] The car front shock absorber mounting plate is usually obtained by drawing and forming a metal plate and then trimming and punching the formed blank. In the prior art, the car front shock absorber mounting plate is cut and punched. Two processes are carried out, the processing efficiency is low, the cost is high, and the accumulated error of multiple clamping and positioning is large, the dimensional accuracy of the processed product cannot be guaranteed, the defective rate is high, and the existing processing mold has a single function and poor performance. The positioning of the workpiece is not firm. During the punching process, the workpiece is prone to slight deformation. After processing, there are burrs on the edge of the workpiece and it is easy to form curling. It needs to be polished and cor...

Problems solved by technology

[0002] The mounting plate of the front shock absorber of the automobile is usually obtained by deep-drawing the metal plate as the raw material, and then trimming and punching the formed blank. In the prior art, the mounting plate of the front shock absorber of the automobile is divided into three parts: Two processes are carried out, the processing efficiency is low, the cost is high, and the cumulative error of multiple clamping and positioning is large, the dimensional accuracy of the processed product cannot be guaranteed, and the rate of defective products is high. In addition, the existing processing mold has a single function and poor performance. The positioning of the workpiece is not firm. During the blanking process, the workpiece is prone to slight deformation. After processing, the edge of the workpiece has burrs and is easy to form curling. It needs to be polished and corrected before entering the next process. The processing process is cumbersome, time-consuming and laborious, and the processing cost is relatively high. High, and there is the defect that it is difficult to take out the parts. The workpiece is often stuck on the mold and is not easy to take out, which affects the continuity of production and the production efficiency is low. However, the impact-type punching rod will exert an impact force on the workpiece, which will not only cause damage to the workpiece, but also eject and scatter the workpiece disorderly under the action of the impact force. The scene is chaotic and has certain safety hazards, which is not conducive to automated production. There is also an elastic jacking device, which is usually set as a spring or elastic rubber to provide elastic force. The size of the elastic force is related to the deformation. It is only used to provide elastic ejection force, and it cannot guarantee that the workpiece will be ejected as required under the action of the ejection force. For workpieces with complex surface structures, the ejection function cannot be guaranteed, and the problem of material jams cannot be avoided. The continuous elastic force will obliquely clamp the workpiece in the mold, making it more difficult to remove the workpiece, and even damage the mold surface
