After using the steel punching machine for a period of time, we will find a lot of dust and dirt in the hole. At this time, I was thinking about how to clean the hole of the punching machine? Let's take a look. < br style = "list style type: none;" / > the punching machine for strip steel needs frequent maintenance to ensure its service life: before operation, check whether the punch and die of the punching machine are matched properly, otherwise the main machine of the punching machine will be damaged. When assembling the upper and lower dies, the models of the upper and lower moulds must be consistent, and the upper die fixing sleeve must be tightened. When placing the lower die, pay attention to the knife edge upward (the end with small hole diameter), and do not install it, but damage the machine. Do not remove the quick coupling when the system has working pressure during operation. The screw rod and nut should be lubricated with oil. < br style = "list style type: none;" / > the component is composed of a steel punching machine body, a main hydraulic cylinder, a slider, a back cover, a guide slide, a die change safety device, an auxiliary pallet, an X-axis positioning device, a discharge box and a waste trolley. The bed is an open structure, which is made by welding steel plates. Pay attention to the cost of cleaning the hole, so as to avoid damaging the machine tool by filling the lower die hole. Before punching, the punching die must be screwed before working. If any abnormal fault is found during the operation, stop punching and eliminate the fault, so as to avoid damaging the machine parts.
