The die of bus machine must be grinded after a long time of use, and the edge surface must be demagnetized after grinding, not with magnetic, otherwise it is easy to block material. Spring and other elastic parts in the use of the spring is the most easy to damage, usually fracture and deformation phenomenon. The way to take is to replace, in the process of replacement must pay attention to the specifications and model of the spring, the specifications and model of the spring through the color, diameter and length of three to confirm, only in the case of three are the same can be replaced. In the process of using the busbar machine die, the punch is easy to break, bend and gnawed, and the punch sleeve is generally gnawed. The damage of punch and punching sleeve is generally replaced with parts of the same specification. Punching parameters mainly include working part size, installation part size, length size and so on. Tighten the parts and check whether the fastening parts are loose or damaged. The method to be adopted is to replace the parts with the same specifications. Pressing parts such as pressing plate, excellent glue, etc., unloading parts such as stripper board, pneumatic top material, etc. Check the relationship between the parts of the maintenance and whether there is damage, repair the damaged part, check whether there is leakage of pneumatic top material, and take measures for the specific situation. The size of the scale is closely related to the tool's task form and detailed task approach. In order to achieve good results, we need to accurately solve and master the elements of the department. If the scope of the agency is solved well, there will be no unnecessary waste. In order to achieve that effect, it is necessary to stop the proper combination of some configurations. For this purpose, the old combination can be changed to six or eight pieces. According to that situation, the need to do something to prevent some of the results that can emerge, so that the request for the range of cutting edge mobilization is much higher. Moreover, this form of speech will lead to a large level of response to the life of the cutting edge. The operation department should strengthen the transformer protection, monitoring and other tasks, in order to effectively prevent the onset of all the transformer tip discharge. CNC bus processing machine bus groove overload power is strong, derived from its use of high insulation data task measurement, CNC bus processing machine bus groove with insulation data adopted task measurement of 105℃ information, has been opened and recovered task measurement of 140℃ above the irradiation crosslinked flame retardant entangling belt (PER) and irradiation crosslinked polyvinyl thermal expansion tube.
