The first-level maintenance of the mold's primary maintenance mold refers to the operation and daily maintenance of the mold during the production, the main content is cleaning, lubrication and inspection. 1. Maintenance of the mold Before cleaning, the upper and lower surfaces of the mold should be cleaned to ensure that the mold mounting surface and the press table are not subject to crushing and the parallelism of the upper and lower mounting surfaces of the mold during production. After the mold is installed, the mold is opened, and the parts of the mold are cleaned, especially the guiding mechanism. For the surface part mold, the surface is cleaned to ensure the quality of the parts. Lubricate the sliding parts of the mold and apply grease. Inspection of all parts of the mold, especially safety parts. Such as: safety side pins, safety screws, side guards, punching waste roads, etc. Second, the maintenance of production in the production of the corresponding part of the mold is regularly oiled. Such as: the drawing ring of the drawing die, the rounded corner; the edge of the trimming die; the part of the flanging block. Regularly clean the waste of the small hole waste road of the trimming punching die. After the production and maintenance, the mold should be thoroughly inspected. The mold is thoroughly cleaned to ensure the cleanliness of the mold. Clean the waste in the mold to ensure that there is no waste in the waste box. The state of use of the mold and the situation after use are faithfully fed back to the mold voucher. Secondary maintenance of the mold The secondary maintenance of the mold refers to the regular system maintenance of the mold according to the technical state and complexity of the mold. This maintenance work is done by the mold repairer and is recorded according to the maintenance situation. The requirements and methods of the second warranty are described below for different parts. Drawing die, die: The main problem of the convex and concave die of the drawing die is the embossing of the napped and profiled surface. The maintenance is mainly to polish the rounded portion of the die. If there is a crater, the mold must be repaired and repaired. Guide parts (guide posts, guide sleeves, guides, etc.): The mold will appear to be scratched during work. The main causes and causes are the dirt of the lubricating oil and the deviation of the guiding gap. The pull marks of the guide parts are removed by polishing with oil stone and then polishing. Trimming knife edge: The blade edge is prone to chipping and edge collapse during the use of the mold. At this time, it is necessary to repair and repair the damaged blade. Elastic parts such as springs: During use, the spring is one of the most vulnerable parts of the mold, and usually breaks and deforms. The method adopted is to replace, but the specification and model of the spring must be paid attention to during the replacement process. The specifications of the spring are determined by the color, outer diameter and length. Only when all three items are the same can be replaced. Punching and punching: Most of the punches and punches used on the molds are made of standard parts. The punches are prone to breakage, bending and smashing during use. Punches are generally smashed. Damage to the punch and sleeve is generally replaced with parts of the same specification. The parameters of the punch mainly include the working part size, the mounting part size, and the length dimension. Fastening parts: Check if the fastening parts are loose or damaged. The solution is to find parts of the same specification for replacement. Pressing and unloading parts: pressing parts such as pressure plate, superior glue, unloading parts such as unloading plates, pneumatic topping devices, etc. During maintenance, check the assembly relationship of each part and whether it is damaged or not, and repair the damaged part. Check the pneumatic top material for air leakage and take measures for specific situations. If the air pipe is damaged, replace it. 7+Person Hot Tub 7+ Person Hot Tub,large outdoor spa,outdoor living pool spa,spa with outdoor heated pool,modern outdoor hot tub Guangzhou Aijingsi Sanitary Products Co.,Ltd , https://www.hottubdesign.com
