< P style = "text indent: 2em;" > the new channel steel punching machine is used to force the metal into the moving part of the die such as sheet processing, stamping, die pressing and embossing. The use of new channel steel punching machine is more and more common, but in the process of using the new channel steel punching machine, what should we pay attention to? The first thing we should pay attention to is the safety production. The site using the new channel steel punching machine should clear the hole position and surrounding rocks and other obstacles according to the requirements of the manual of the new channel steel punching machine. The distance between operation site and power transformer or main power supply line shall be within 200m, and voltage drop during startup shall not exceed 10% of rated voltage. The motor and control box shall have good grounding device. Before installation, check and confirm that the punch bar and its components are free of deformation; after installation, the allowable deviation of the center line between the punch and the power head is 1% of the total length. When installing the punch rod, it should start from the power head and install it from section to section. It is not allowed to lift and install the required punch length on the ground. Before the installation of power head, the pulley block should be removed and the wire rope should be wound. The selection of wire rope shall be in accordance with the requirements specified in the manual. After installation, the frequency of the power supply should be the same as the pointer on the frequency conversion switch in the control box. If not, the frequency conversion switch should be used for conversion. The punching machine should be placed stably and solidly. The new channel steel punching machine of automobile type should be supported with legs to support the tire, and the tappet should be adjusted by automatic fine adjustment or linear hammer to keep it vertical. < br style = "list style type: none;" / > the new type channel steel punching machine is a newly developed high-precision product with two patents, i.e. bow punching machine. The punching speed of the punch of the new channel steel punching machine is 2.5 times of that of the similar products, and the blanking force is increased. The installation position of viewfinder is fixed and the camera is direct, which overcomes the data change caused by the viewfinder movement, improves the positioning accuracy of workpiece, and greatly improves the reliability of data acquisition and workpiece positioning. The technology has the advantages of saving energy more than 50% compared with other equipment, and greatly reduces the energy consumption and working noise of the equipment.
