Problems solved by technology

Its shortcomings are: 1. Only one side of the hole can be punched at a time
2. Only one type of hole can be punched. If the hole diameters of the two sides of the hardware rod are inconsistent, the punch needs to be replaced and the secondary punching is performed, and the production efficiency is low.
3. During the punching process, the metal rod is easy to deform and bulge

Abstract

The invention discloses a bilateral special-shaped hole puncher. In the bilateral special-shaped hole puncher, a left punch and a right punch are driven by a left hole punching oil cylinder and a right hole punching oil cylinder so as to punch holes on a metal rod piece which is clamped in an upper mould semicircular groove and a lower mould semicircular groove. An upper mould is fixed on an upper mould pressure plate; the upper mould pressure plate is fixed on the piston rod of an upper mould driving oil cylinder; a lower mould is fixed on a working table; the upper mould semicircular groove, an upper mould piece-fetching square groove and a positioning square groove are formed on the upper mould; the lower mould semicircular groove, a lower mould piece-fetching square groove and a step are formed on the lower mould; the upper mould semicircular groove is opposite to the lower mould semicircular groove; the upper mould piece-fetching square groove is opposite to the lower mould piece-fetching square groove; and the positioning square groove is clamped on the step. The holes with different diameters can be punched on the two sides of the metal rod piece at the same time by the bilateral special-shaped hole puncher, a workpiece is convenient to fetch and place, and production efficiency is improved; meanwhile, the moulds of the bilateral special-shaped hole puncher can ensure that the metal rod piece does not deform greatly in the hole punching process, and the yield of products is high.

Description

Technical field: [0001] The invention relates to the technical field of punching machines, in particular to a punching machine for simultaneously punching two sides of a hardware rod. Background technique: [0002] At present, the general metal bar punching machine in China uses an ordinary punching machine to punch holes. The ordinary punching machine drives the eccentric wheel to rotate through the motor, and the eccentric wheel acts on the punch rod. The parts are punched. Its disadvantages are: 1. Only holes on one side can be punched at a time. 2. Only one type of hole can be punched. If the hole diameters on the two sides of the hardware rod are not consistent, the punch needs to be replaced and the secondary punching is performed, and the production efficiency is low. 3. The metal rod is easy to deform and bulge during the punching process. Invention content: [0003] The purpose of the present invention is to provide a double-sided different-diameter punching ma...
