Punching blanking device for automobile sheet metal part

Abstract

The invention discloses a punching blanking device for an automobile sheet metal part. The punching blanking device structurally comprises a maintenance cabinet door, a workbench main body, a connecting lead, a pneumatic punching device, a supporting mounting frame, an overflow fixing, lubricating and cooling device and a blanking cavity. The maintenance cabinet door is connected with the left endface of the workbench main body in a hinged mode. One end of the connecting lead is embedded and mounted in the upper surface of the workbench main body. The other end of the connecting lead is connected with the pneumatic punching device in a nested mode. The clamping force to a workpiece can be accurately controlled, the phenomenon that the surface of the machined part is scratched due to too high clamping force or the machined part is liable to be deviated by stress due to too low clamping force in the machining process is avoided, the punching quality is ensured, in addition, lubricatingliquid is sprayed out for lubricating and cooling while the machined part is machined by the device, and the situation that the machining temperature of the device is too high, consequently, the workpiece surface finish is affected, and the machining precision is lowered is avoided.

Description

technical field [0001] The invention relates to the field of punching and blanking devices, more precisely, a punching and blanking device for automobile sheet metal parts. Background technique [0002] Use a press to separate the required material from the base material of the plate, generally called blanking, and use various methods to separate the material from the base material, which is called blanking. Various graphics are punched on materials such as wood and wood to meet different needs. However, the current punching and blanking device has the following disadvantages: [0003] 1. The accuracy of the device’s control of the clamping force of the workpiece is low, and it is easy to cause scratches on the surface of the workpiece if the clamping force is too high, or if the clamping force is too small, it is easy to be displaced by force during the processing and affect The quality of stamping. [0004] 2. Moreover, the cooling effect of the equipment on the workpiec...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a punching and blanking device for automobile sheet metal parts to solve the problem that the device in the prior art has low accuracy in controlling the clamping force of the workpiece, and it is easy to make the clamping If the clamping force is too large, scratches will be generated on the surface of the workpiece, or if the clamping force is too small, it will be easily displaced by force during the processing, which will affect the quality of stamping, and the cooling effect of the equipment on the workpiece is poor, resulting in During the process, the temperature rises rapidly, which affects the surface finish of the workpiece and reduces the defects of machining accuracy.
