Talking about the maintenance of the mold of the die cutting machine
Mold maintenance is divided into primary maintenance and secondary maintenance. Mold primary maintenance. The first-level maintenance of the mold refers to the daily maintenance of the mold by the operator during production, and the main content is cleaning(High Speed Slitting Machine)
Rub, lubricate and inspect. The secondary maintenance of the mold refers to the regular systematic maintenance of the mold based on the technical status and complexity of the mold.
Primary maintenance of mold
1. Maintenance during mold installation
A. Clean the upper and lower surfaces of the mold before installing the mold to ensure that the mold mounting surface and the press table are not crushed and the mold is parallel to the upper and lower mounting surfaces during production.
B. After the mold is installed, open the mold and clean all parts of the mold, especially the guiding mechanism. For the surface mold, the surface of the mold is cleaned to ensure the quality of the part. 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 channels, etc.
2. Maintenance in production
A. Regularly apply oil to the corresponding parts of the mold during production. Such as: the press ring and fillet of the drawing die; the knife edge of the trimming die; the flanging knife block part, etc.
B. Regularly clean the small hole waste passage of the trimming punching die.
3. Maintenance after production
A. A comprehensive inspection of the mold is required after production.
B. The mold is thoroughly cleaned to ensure the cleanliness of the mold.
C. Clean up the waste in the mold to ensure that there is no waste in the waste box.
D. Faithfully feedback the mold's use status and the situation after use to the mold voucher.
Secondary maintenance of mold
This maintenance work is completed by mold repair personnel, and records are made according to the maintenance situation. The following describes the requirements and methods of the second warranty for different parts.
1. Convex and concave die of drawing die: The main problem of the convex and concave die of the drawing die is the napping and the pressing pit of the molding surface. During maintenance, the round corner napping part of the mold is mainly polished. If there is a crater, the mold should be repaired and then repaired.
2. Guide parts (guide posts, guide sleeves and guide plates, etc.): the mold will have pull marks during work. The main causes are dirty lubricating oil and guide gap deviation. The pull marks of the guide parts are eliminated by polishing after smoothing with oilstone.
3. Trimming the edge: the edge part of the mold is prone to chipping and edge collapse during the use of the mold. At this time, the damaged knife edge of the mold should be repaired by welding.
4. Springs and other elastic parts: During use, the spring is one of the most vulnerable parts of the mold, and it usually breaks and deforms. The method adopted is to replace, but during the replacement process, you must pay attention to the specifications and models of the springs. The specifications and models of the springs are determined by the three items of color, outer diameter and length. Only when these three items are the same can they be replaced.
5. Punches and sleeves: most of the punches and sleeves used on the mold are made of standard parts. The punches are prone to breakage, bend and gnaw during the use of the mold. Cushioning is generally broken. The damage of the punch and sleeve is generally replaced with parts of the same specification. The parameters of the punch mainly include the size of the working part, the size of the installation part, and the length dimension.
6. Fastening parts: Check whether the fastening parts are loose or damaged. The method adopted is to find parts of the same specification for replacement.
Rub, lubricate and inspect. The secondary maintenance of the mold refers to the regular systematic maintenance of the mold based on the technical status and complexity of the mold.
