Problems solved by technology

Due to the two times of clamping, not only the efficiency is low, the energy consumption is high, but also the concentricity of the two punching holes cannot meet the requirements due to the second clamping, resulting in defective products

Abstract

The invention discloses a method and device for double-faced punching. The device comprises an inclined face supporting mechanism, a moving concave die fixing seat, a moving concave die base, a moving concave die, a convex die base, a convex die, a fixed concave die, a fixed concave die base, a fixed concave die fixing seat, an oil cylinder, a tail end pushing cylinder, a U-shaped block, a bracket, a moving concave die clamping cylinder piston connecting seat, a moving concave die clamping cylinder, an inclined face supporting locking cylinder, a convex die linear guide rail pair, a public linear guide rail pair, a moving concave die linear guide rail pair and a punch base. Compared with an original machining method, according to the method and device for double-faced punching, more space is saved, one punch can replace two common punches, work efficiency is high, manpower is saved, and the defective percentage of machined products is low.

Description

technical field [0001] The invention belongs to the field of pipe material processing, and in particular relates to a double-sided punching method and device. Background technique [0002] When punching semicircular holes on both sides of the pipe ends of the automobile suspension system, two processes were used in the past. The original punching method used two sets of molds and a large-tonnage general-purpose vertical punch or two small-tonnage general-purpose vertical punches. After the pipe is clamped on the first set of molds and punched on one side, the pipe is removed, then clamped to another set of molds, and the other side is punched. Due to the two times of clamping, not only the efficiency is low, but the energy consumption is high, and because of the second clamping, it is very easy for the coaxiality of the two punching holes to fail to meet the requirements, resulting in defective products. Contents of the invention [0003] The invention provides a double-s...
