Description

Technical Field

[0001] The utility model relates to a bushing stamping die for automobiles, belonging to the technical field of stamping dies. Background Art

[0002] Cold stamping is a processing method that uses a die to apply pressure to the material on a press at room temperature to separate or deform it, thereby obtaining a certain shape, size and performance part. The cold stamping process has the following characteristics: cold stamping can process parts with thin walls, light weight, complex shapes, good surface quality and good rigidity. The dimensional tolerance of cold stamped parts is guaranteed by the die, and it has the characteristic of "exactly the same", so the product quality is stable. Cold stamping is one of the processing methods with little or no chips. It is an energy-saving, low-consumption and high-efficiency processing method, so the cost of stamping parts is low. Cold stamping production relies on presses and dies to complete the processing process. It has high productivity, simple operation, and is easy to mechanize and automate. Using ordinary presses for stamping processing, it can reach dozens of pieces per minute, and using high-speed presses, it can reach hundreds or thousands of pieces per minute.

[0003] Classification of cold stamping processes. Due to the different shapes, sizes, precision requirements, batch sizes, raw material properties, etc. of cold stamping parts, there are many different stamping methods.

[0011] The upper top plate 2 and the lower bottom plate 9 are made of 45# steel material.

[0012] The upper die 5, the retaining ring 6 and the lower die 7 are made of Cr12Mo1v1 material.

[0013] The upper top plate 2 is fixed to the bottom of the top beam of the pneumatic punch by the die handle 1 by the clamp and bolts, and the lower bottom plate 9 is fixed to the working table of the pneumatic punch by the clamp and bolts. The bushing 11 to be punched is placed in the retaining ring 6, and the power switch is turned on. The upper die 5 is driven downward by the upper top plate 2 to move the upper top plate 2, and the bushing 11 in the retaining ring 6 is punched into the required shape and size.

[0014] Pneumatic punching machines are more hygienic and clean. photoelectric Protection technology can greatly improve safety performance. The combination of computer counting and program can realize unattended processing, greatly improving work efficiency and reducing production costs. The equipment has a simple structure and adopts pneumatic technology, so that one air compressor can supply multiple pneumatic punching machines at the same time, reducing power consumption.
