Punch of stamping die

Abstract

The invention belongs to the technical field of automobiles, and particularly relates to a punch of a stamping die. The punch comprises a punch body, a piston rod, a cylinder barrel, a fixed seat, a first switch deflation valve and a second switch deflation valve; one end of the punch body is fixedly connected with the piston rod; the fixed seat is fixedly connected with the stamping die; the punch body is fixed on the fixed seat; the cylinder barrel is divided into a first air chamber and a second air chamber through the piston rod; the second switch deflation valve is arranged at the openingof the first air chamber; the first switch deflation valve is arranged at the opening of the second air chamber; the first switch deflation valve is fixedly connected with a workshop compressed air pipe; and the second switch deflation valve is fixedly connected with the workshop compressed air pipe. The punch is suitable for the field of production and manufacturing of stamping covering parts onthe outer surface of an automobile, after the punch is fixed on the stamping die, the working and hiding states of the punch can be controlled through an air channel, and the problem that the punch of the die is frequently disassembled and assembled is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to a punch of a stamping die. Background technique [0002] In the manufacturing process of stamping and covering parts on the outer surface of automobiles, it is often encountered that the same part needs to be replaced online due to the number and position of holes. Under the existing conditions, the replacement of the punch adopts the method of manual disassembly and assembly. Due to the limitation of the workplace, the replacement procedure is complicated and time-consuming. Under the trend of automated production, it has become a shortcoming that affects production efficiency. [0003] In addition, stamped covering parts on the outer surface of automobiles are widely used in the production of complete vehicles. The number of holes for the same part needs to be adjusted according to the demand. In the previous production method, the punch for punching is fixed in the mold an...

Problems solved by technology

Under the existing conditions, the replacement of the punch adopts the method of manual disassembly and assembly. Due to the limitation of the work site, the replacement procedure is complicated and time-consuming. Under the trend of automated production, it has become a short board that affects production efficiency.

[0003] In addition, stamped covering parts on the outer surface of automobiles are widely used in the production of complete vehicles. The number of holes for the same part needs to be adjusted according to the demand. In the previous production method, the punch for punching is fixed in the mold and needs to be placed Dismantling and assembling punches according to requirements before or during production affects production efficiency and causes waste of manpower and material resources
