Silencing pipe punching machine

Abstract

The invention discloses a silencing pipe punching machine, and belongs to the technical field of machining of silencing pipe punching machines. The silencing pipe punching machine comprises a rack, amaterial pushing device, a feeding device, a punching machine and a control box. The material pushing device, the feeding device, the punching machine and the control box are mounted on the table surface of the rack. The material pushing device comprises a material frame. A hopper is mounted above the material rack. A material seat is arranged below a clamping cavity of the hopper and is fixedly mounted on the table surface of the rack. A material pushing plate is arranged on the upper portion of the material seat. A feeding air cylinder is mounted at the left end of the material pushing plateand is fixedly mounted on the table surface of the rack. The feeding device comprises a second line rail. Integrated automation of the silencing pipe machining process is achieved. Contingencies caused by punching operation conducted by manually holding a silencing pipe are favorably avoided. The safety of the machining operation is enhanced. The labor intensity of personnel is reduced. The machining efficiency is improved. Workpiece punching is uniform. The silencing effect of the silencing pipe is guaranteed.

Description

technical field [0001] The invention relates to the technical field of punching processing for silencer pipes, in particular to a punching machine for silencer pipes. Background technique [0002] The perforated muffler pipe is an important component of the muffler. The punched plate is bent into a tubular shape and used as a muffler. The material used is stainless steel, galvanized sheet, etc. This original plate punching first, then bending and welding into a tubular shape, not only has a complicated process, but also adopts strict seamless welding technology for the seam of the welding part to ensure the seam quality of the muffler pipe, and the seamless welding not only The technical requirements for the welding operation are high, and the welded part needs to be finely ground after welding to ensure the smoothness of the muffler pipe surface. The process is cumbersome and complicated, the operation requirements are high, and the production time is long. [0003] Theref...
