Abstract

The invention provides a bidirectional impact cylinder. The bidirectional impact cylinder is composed of a cylinder barrel, a sealing piston, a piston rod, a front end cover, a front middle cover and a back end cover, wherein the tail of the sealing piston and the piston rod are fixedly connected; the front end cover, the front middle cover and the cylinder barrel of the cylinder form a front air storage cavity; the front middle cover, the head of the sealing piston and the cylinder barrel form a rodless cavity; the tail of the sealing piston, the back end cover and the cylinder barrel form a rod cavity; a back middle cover is further arranged between the tail of the rod cavity and the back end cover, and the back middle cover, the back end cover and the cylinder barrel form a back air storage cavity; the outer side of the back middle cover is sealed with the cylinder barrel through a back middle cover first seal ring; and pressure in the front air storage cavity and the rod cavity acts on two ends of the sealing piston respectively, and the back air storage cavity acts on the piston rod return process. The bidirectional impact cylinder has the advantages that the back middle cover is arranged, the return speed of the impact cylinder is increased, the reverse impact force is improved, and the working efficiency is guaranteed; and the piston rod and the back middle cover are protected by a buffer air path of a breather pipe, the structure is simple, the operation is reliable, and the maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of pneumatic transmission components in mechanical automatic control, in particular to a two-way impact cylinder. Background technique [0002] The impact cylinder is a special functional cylinder specially developed to meet the occasions that have high requirements for impact force. The impact cylinder is characterized by strong impact force, fast speed, and low air consumption. It is widely used in blanking and punching. , dismantling, crushing, riveting, pressing, printing, bending and other certain operations. However, in many different working occasions and working conditions, it is not only necessary to provide a strong impact force, but also has a great requirement for the return tension. At the same time, in order to meet the needs of today's industrial production and realize the free control of the response time and return tension of the cylinder, it is very important for the impact cylinder. urgen...
