Abstract

The invention discloses an automobile punching die. The automobile punching die comprises a base. The two sides of the top of the base are fixedly connected with support columns. A top plate is arranged on the surfaces of the support columns in a sleeving manner. An air cylinder is fixedly arranged on the top of the top plate. A punching rod is arranged at the bottom of the air cylinder, the top of the base is movably connected with a bottom plate, and the position, corresponding to the punching rod, of the top of the bottom plate is movably connected with a die body. A first limiting plate iswelded to the front face of the top of the base, first electric telescopic rods are connected between the bottom plate and the first limiting plate through bolts, a first electronic ruler is connected between the bottom plate and the first limiting plate through bolts, and the two sides of the die body are movably connected with second electric telescopic rods. Through cooperation of the first electric telescopic rods, the first electronic ruler, the second electric telescopic rods, a second limiting plate, a second electronic ruler and a control box, the problems that an existing punching die is not accurate enough in positioning, and consequently the rejection rate is high are solved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an automobile stamping die. Background technique [0002] At present, with the rapid development of the automobile industry, the stamping and molding of parts is indispensable in the process of producing automobiles. Many body stamping parts are produced by first blanking to obtain the required contour edge line, and then forming again. method. This type of process can save the subsequent trimming work, thereby saving the trimming mold and effectively reducing the cost of the mold. However, this process method requires high positioning of the plate. If the position of the edge line of the stamped part is unstable, the outer contour dimensions of the parts obtained by each stamping will be inconsistent, resulting in a decrease in the product yield. It is proposed in the Chinese invention CN206997503U A positioning device for automobile stamping dies has been dev...
