Description

Punch and angle steel punching machine Technical Field The invention relates to the technical field of angle steel manufacturing, in particular to a punch and an angle steel punching machine. Background The angle steel punching machine consists of a manual pump or an electric pump and a working head, wherein an oil conveying hose is connected by adopting a quick connector, the oil conveying hose is reliable and quick in sealing, has no directional limitation during operation, is convenient to assemble and disassemble, is specially used for punching metal plates such as angle iron, flat iron, copper, aluminum bars and the like and is used for punching angle steel, and when in operation, the angle steel can be processed by only putting the angle steel into a feed inlet, and the processing requirements are set, so that the efficiency is high and the end face is flat. In the production practice process, the principle of equipment punching is that a punch is used for doing work on angle steel under high pressure, so that punching is realized, the mode has the advantages of flattening a pore canal, and the defect that the punch is damaged by periodical stress, and the punch is made of hard alloy steel, so that the wear resistance is good, the punch becomes a consumable product under the nuclear power general operation task, when the punch is damaged, the existing punch is integrally arranged, so that when a worker needs to replace the whole equipment of the punch, the whole punch has to be disassembled, the production cost is high, and meanwhile, the worker needs to integrally replace after the tip of the punch is damaged, so that the labor intensity of the worker is high, and the integral work efficiency is influenced. Disclosure of Invention The invention aims to provide a punch and an angle steel punching machine, which are used for solving the technical problems that when the punch is damaged by periodic stress working in the prior art, the tip of the punch needs to be integrally replaced after being damaged, so that the labor intensity of staff is high and the overall working efficiency is influenced.
