< P style = "text indent: 2em;" > the punching machine for strip steel is made of special die steel, which is safer in structure and easier to install. So how to use the punching machine can effectively reduce the failure of the punching machine? < P style = "text indent: 2em; " > < br / > 1. Determine whether the punching machine is a multi fixture or a single fixture. When the punching machine with multi fixture is applied, only one fuel pipe power switch is turned on at a time to carry out the work, and several other fuel pipe power switches can not be turned on. Many people operate in order to improve the work efficiency, and will be applied in multiple channels, which will cause bad harm to the operation of the machine and the quality of production and processing. On the other hand, when the steel punching machine is working, insert the grinding tool into the pipe fitting to carry out punching. It is forbidden to carry out empty punching when there is no pipe fitting, otherwise the abrasive tool will be damaged. When punching the whole hole, if it is not punched through, it will automatically return, please sink the lower proximity switch downward, so as to maintain the abrasive tool. < br / > 2. Regular inspection and maintenance shall be carried out for the punching machine of strip steel after operation. Check whether the edge of the punching needle has been passivated for a long time. If it has been passivated, please remove the punching needle and grind it, or buy a new punching needle from the manufacturer. In winter, the average temperature will decrease, so as to maintain the machinery and equipment, it is necessary to start the air transportation for a period of time to heat up the machine; if the machine and equipment are in operation for a long time, check the temperature of the machine and equipment, and the temperature of the gear oil should be controlled between 30-60 ℃.
