Multi-hole hydraulic punching machine with adjustable punching positions

Abstract

The invention discloses a multi-hole hydraulic punching machine with adjustable punching positions. The multi-hole hydraulic punching machine solves the problem that in an existing power system, a metal hole plate multi-hole machining process is complex, and the positions and quantity of punched holes are difficult to adjust. The multi-hole hydraulic punching machine is characterized by comprisinga material return plate, material return plate supporting blocks, a lower mold plate, a connecting plate, an upper mold plate, a male mold and the like; the upper mold plate is connected to the connecting plate, the lower mold plate is arranged between the material return plate supporting blocks, a sliding groove of the upper mold plate is provided with a protruding convex edge, a nut rotating base of the male mold is in threaded connection with a male mold cylinder, and the quantity and size of lower mold plate long groove holes of the lower mold plate correspond to those of the male mold. According to the multi-hole hydraulic punching machine, according to different thread tightening degree, the male mold can be moved and fixed in the sliding groove of the upper mold plate, and quick adjustment of different-hole distance machining of the metal hole plate is achieved; one more holes can be punched at a time, the upper mold plate, the male mold and the lower mold plate can be in multiple specifications, multiple holes at different positions and in different specifications can be punched, the production efficiency is greatly improved, and only one person is needed for operation.

Description

technical field [0001] The invention relates to a punching device, more specifically to a punching machine for punching multiple holes at a time. Background technique [0002] In the power industry, it is often necessary to punch holes in metal plates such as flat iron and copper plates, as well as equipment clamps. Hydraulic punching machine is a more convenient and practical punching tool. However, the current hydraulic punching machine can only fill one hole, the punching position of the entire upper template cannot be adjusted, it can only be punched at a specific position, and the punching die can only be used in a specific hole, and the existing It is inconvenient to use the punching machine without a stripper. Because of these deficiencies, the limitation of use has been caused, the difficulty of operation has been increased, and the work efficiency has been reduced. Contents of the invention [0003] The purpose of the present invention is to overcome the shortco...
