Automobile side punching trimming and hole flanging die

Abstract

The invention discloses an automobile side punching trimming and hole flanging die. The die comprises an upper die plate and a lower die plate, the upper die plate is connected with a punching machine, the lower die plate is fixed to a base, a pressing plate is arranged on the upper die plate, an open hole is formed in the pressing plate, a trimming male die is arranged in the open hole, the top of the pressing plate and the top of the trimming male die are both fixedly connected with the bottom of the upper die plate, the trimming male die extends to the outer side of the pressing plate, and a gap exists between the trimming male die and the pressing plate; and the two sides of the pressing plate are each provided with a first sliding groove. According to the automobile side punching trimming and hole flanging die, the side punching process, the side hole flanging process and the trimming process can be carried out at the same time, the punching time is shortened, the production period is shortened, the production efficiency is improved, a production die is saved, the investment cost is reduced, the die mechanical jacking manner does not need to consume power, manpower resources and material resources can be saved, energy consumption is reduced, and the extremely high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of automobile molds, in particular to a mold for side punching, trimming, and turning holes of automobile parts. Background technique [0002] Under the correct guidance of the national industrial policy, after decades of hard work, the design and manufacturing capabilities of stamping dies in my country have reached a relatively high level, and many modern design and manufacturing technologies, including information engineering and virtual technology, have been applied in many mold companies. Even so, there is still a big gap between my country's stamping die design and manufacturing capabilities, market demand and the international advanced level. These are mainly manifested in high-end cars and large and medium-sized car panel molds and high-precision punching dies. There is a big gap in terms of design, processing technology and capabilities. The car panel mold has the characteristics of difficult desig...
