Problems solved by technology

[0002] At present, the automobile body panel mold is the mold with the highest requirements and the most difficult processing in the automobile body manufacturing, and it is also the rapidly developing cold stamping process equipment in the manufacture of mechanical and electrical products in my country. A variety of car models need to be processed on one processing platform, some need to be punched, and some do not need to be punched. According to the current processing technology, it is generally necessary to increase the punching process, which greatly increases the manufacturing cost of the mold itself. , increasing the mold change time and reducing production efficiency

Embodiment Construction

[0011] A lifting punching device, the punch 10 is set on the die base 20, and the die base 20 is provided with an adjustment mechanism 30 for adjusting the height of the punch 10 and a limit mechanism 40 for limiting the movement direction of the punch 10. When punching is required, the punch 10 can be raised by the adjusting mechanism 30 ; when punching is not needed, the punch is also lowered by the adjusting mechanism 30 . The limit mechanism 40 is mainly used to ensure that the punch 10 is always lifted and lowered in the vertical direction during the process of raising and lowering, so as to achieve the purpose of accurate punching.

[0012] The adjustment mechanism 30 includes upper and lower sliders 50, 60 that move in opposite directions, the mating surface between the upper and lower sliders 50, 60 is an inclined plane, and the upper and lower sliders 50, 60 are located in the mold cavity of the mold base 20 21, the upper end surface of the upper slider 50 is attached...

Abstract

The invention relates to the field of automobile manufacturing, in particular to a lifting punching device which realizes effective switching to or not to punch without removing a mould. The technical scheme adopted by the invention is as follows: in a lifting punching device, a punch is arranged on a mould seat, and an adjusting mechanism for adjusting the height of the punch and a limit mechanism for limiting the moving direction of the punch are arranged in the mould seat. Through the technical scheme, the adjusting mechanism can realize the lifting movement of the punch, and the limit mechanism can ensure that the punch always moves in the vertical direction during the lifting. The device is simple to operate, convenient to use and low in manufacturing cost, and can effectively save the mould development cost and improve the production efficiency.
