Punching die for processing oil storage barrel

Abstract

The invention discloses a punching die for processing an oil storage barrel. The punching die comprises a working table (1), a standing column A (2) and a standing column B (3), wherein the standing column A (2) and the standing column B (3) are arranged on the working table (1), a semicircular groove (6) matched with the blank shape is formed in the top of a bearing table (5), the right end of the bearing table (5) extends outside the standing column B (3), a vertical hydraulic cylinder (7) is also fixedly installed on a beam (4), a piston rod of the hydraulic cylinder (7) penetrates through the beam (4), a punching head (8) is connected to the effect end of the piston rod of the hydraulic cylinder (7) and located over the semicircular groove (6), and the bearing table (5) is located between a discharging plate A (9) and a discharging plate B (10). The punching die has the advantages that separating between a product and the punching head is rapidly achieved, the processing efficiency is improved, and it is achieved that rectangular grooves are processed at different positions of a blank, the labor strength of workers is reduced, and operation is easy.

Description

technical field [0001] The invention relates to the technical field of processing oil storage cylinders, in particular to a die for processing oil storage cylinders. Background technique [0002] Shock absorbers for automobiles are mainly composed of spring discs, oil storage cylinders, springs and other components. The blank for processing the oil storage cylinder is a hollow tube, and the outer wall of the hollow tube is processed with rectangular grooves. At present, the existing equipment for processing rectangular grooves includes a hollow round mold and a hydraulic press. A pressure head is installed on the piston rod of the hydraulic press, and a square groove is arranged on the top of the mold. The square groove communicates with the hollow circle mold. When producing and processing the oil storage cylinder, Insert the hollow round tube into the round hole of the hollow round mold first, then control the piston rod of the hydraulic press to extend downward, the pisto...

Problems solved by technology

[0003] However, after processing, the outer wall of the finished oil storage cylinder is tightly attached to the round hole of the hollow circular mold. When taking out the product, the worker needs to use a hammer to hit the end face of the finished oil storage cylinder to push the product out of the hollow circular mold. This method of retrieving materials has the disadvantages of time-consuming, labor-intensive and heavy labor

[0004] In addition, for blanks of different specifications, the distance between the rectangular groove on the blank and the end face of the blank is different. In order to realize the processing, it is often necessary to replace the molds of different sizes for processing, which undoubtedly increases the production cost. reduced productivity
