Pneumatic double head punching machine

Abstract

The invention discloses a pneumatic double-head drilling machine. The pneumatic double-head drilling machine comprises a base, wherein a frame body is welded at an upper end of the base, two air cylinders are symmetrically and fixedly installed at an upper end of the frame body, a horizontally-arranged connecting plate is welded at the bottom of an output end of each air cylinder, an installing shell is welded to the bottom of each connecting plate, two vertically-arranged rails are fixedly connected to an inner side wall of each installing shell in parallel, the two rails located inside the same installing shell are slidably connected with a first sliding rod and a second sliding rod correspondingly, a synchronous driving mechanism is arranged between the part where the first sliding rodand the second sliding rod are located in the same installing shell, and the lower end of the first sliding rod and the lower end of the second sliding rod both extend to the outside of the installingshell in a penetrating manner. According to the pneumatic double-head drilling machine, two metal plates can be drilled at the same time, the machining efficiency is higher, the energy utilization rate of the air cylinders is higher, the drilling speed is higher, and the deilling effect is better.

Description

technical field [0001] The invention relates to the technical field of pneumatic punching machines, in particular to a pneumatic double-head punching machine. Background technique [0002] Pneumatic punching machine is a stamping machine that uses the impact force of the cylinder and the drill bit to punch holes in the workpiece. Pneumatic double-head punching machine is a punching machine that uses two cylinders to punch holes at both ends of a metal plate at the same time. It has the characteristics of high operating frequency, strong wear resistance and long service life. However, the existing pneumatic double-head punching machine can usually only punch a piece of sheet metal at a time, the processing speed is slow, and the energy utilization rate of the cylinder is low. [0003] To this end, we propose a pneumatic double-head puncher. Contents of the invention [0004] The purpose of the present invention is to solve the problems that the existing pneumatic double-h...
