Graphite mold maintenance
After the mold frame mold is opened, the various parts of mold cleaning Sassafras clean, especially the guiding mechanism for the surface parts (parts) of the mold surface cleaning Sassafras clean, to ensure the quality of the product. For each part of the sliding mold lubrication and die parts of the examination, especially the safety components (such as punch waste hole etc.).
1. press the punching shear of the mold size, correct use of sufficient tonnage of punch (general machine tool tonnage must be greater than the die punching shear)2. in the mold before the machine, you must check the adjustment of the mold arrow blade gap, in order to transport the loading and unloading of the mold when the blade gap clearance, adjustment can be later on the machine3. molds should clean the upper and lower surfaces of the mold to ensure that the die mounting surface and punch work table pressure, damage to the mold in the production of the upper and lower mounting surface parallelism4 the working surface of the punch and the bottom of the slider must be parallel, the deviation of parallelism should be less than 0.03
After the sample has been rushed out, it must be immediately confirmed whether it is in conformity with the specifications of the product
After use, die maintenance:1., after a long use of the mold must be grinding edge, grinding after cutting edge must be demagnetization, not with magnetic, or prone to blocking.2. spring and other elastic parts in the use of the process, the spring is most likely to damage, usually fracture and deformation. The approach is replaced, the replacement process must pay attention to the spring spring specifications and models, specifications and models with color, diameter and length of three to three are confirmed, only in the same circumstances can change.3., the use of the mold in the process of punching easily break, bend and bite the phenomenon, the punch is generally gnaw bad. Damage to punches and covers is usually replaced by parts of the same specifications. The parameters of the punch mainly include the work part size, the installation part size, the length, size and so on.4., fastening parts, check the fastening parts are loose or damaged phenomenon, the method is to find the same specifications of parts for replacement.The 5. pressing parts such as pressure plate, rubber, unloading parts such as stripper, pneumatic ejector etc.. Maintenance, check the parts of the relationship between parts and there is no damage, repair the damaged parts, pneumatic top check, there is no leakage phenomenon, and specific measures taken. If the trachea is damaged, replace it.
Maintenance in production:1. when the mold is used, the guide post and guide sleeve should be lubricated regularly2., in the production of regular corresponding parts and edges of the mold should be repeated lubrication or stamping oil3. in addition to other items prohibited double punching, stamping materials, lubricants should be far away from the work area.4. edges of the iron powder can not delay too much, should be timely source of retention of materials and regular cleaning of scrap, after the end of the production of the mold to conduct a comprehensive inspection, comprehensive cleaning, guarantee the cleanliness of the mold.
