Punching and shearing section of double-shearing and double-punching centralized positioning cut-to-length line

Abstract

The invention relates to a punching and shearing section of a double-shearing and double-punching centralized positioning cut-to-length line The punching and shearing section comprises a punching machine (3) and a shearing machine (4) in sequence from right to left; the punching and shearing section is characterized in that the punching machine (3) comprises a punching mechanism (3.1) and a V-punching mechanism (3.2) which are arranged from right to left, and the shearing machine (4) comprises a first shearing machine mechanism (4.1) and a second shearing machine mechanism (4.2) which are arranged on a shearing machine base from right to left, wherein a shearing machine body of the first shearing machine mechanism (4.1) conducts two types of angle adjustment, namely 90 degrees and 135 degrees, a shearing machine bottom seat of the first shearing machine mechanism (4.1) is connected with the output end of an adjusting air cylinder, and the shearing machine angle of the second shearing machine mechanism (4.2) is fixed to be 45 degrees. The punching and shearing section of the double-shearing and double-punching centralized positioning cut-to-length line has the advantages that materials are conveyed along the center of a conveying channel and not prone to being worn, and the shearing angle of a shearing machine section is convenient to adjust.

Description

technical field [0001] The invention relates to a punching and shearing section with two shears and two punches and a centrally positioned transverse shear line. Background technique [0002] The silicon steel sheet CNC shearing machine tool is mainly used for cutting the silicon steel sheet used in transformers to meet various shape requirements. The existing CNC shearing machine tools for silicon steel sheet can be roughly divided into two types: the first one is that the feeding mechanism is fixed, the feeding roller is long, the material is positioned on the side of the cutting channel, the punching section can be moved, and the shearing machine is fixed. Yes, it has a reference busbar, which is convenient for debugging; the disadvantage is that the long side part of the feed roller is partially worn for a long time, which affects the accuracy; the quality of the feed roller is large, and when the feed roller starts and brakes at high speed, its inertia is large, and hig...

Problems solved by technology

The existing CNC shearing machine tools for silicon steel sheet can be roughly divided into two types: the first one is that the feeding mechanism is fixed, the feeding roller is long, the material is positioned on the side of the cutting channel, the punching section can be moved, and the shearing machine is fixed. Yes, it has a reference busbar, which is convenient for debugging; the disadvantage is that the long side part of the feed roller is partially worn for a long time, which affects the accuracy; the quality of the feed roller is large, and when the feed roller starts and brakes at high speed, its inertia is large, and high-speed feeding is not accurate.

The second is that the feeding mechanism is fixed, centrally positioned, short feeding rollers, the material is centrally positioned on the shearing channel, the punching section can be moved, the +45° and -45° shearing section is fixed on the slide plate, and the shearing section is also The overall movement has the advantages of central positioning feeding, the feeding roller is not easy to wear, the feeding roller is light in weight, small in inertia, and high-speed feeding is accurate; the disadvantage is that it lacks busbar positioning. According to materials of different widths, the material channel must be based on the center line. To adjust both sides, the shearing section must be moved as a whole. Since the weight of the shearing section is about 1 to 2 tons, it is very laborious to move, which is very unreasonable, and it is not easy to receive the silicon steel sheet material after punching and shearing.
