The primary maintenance of the mold refers to the daily maintenance of the mold by the operator in the production. The main contents are cleaning, lubrication and inspection.
A, maintenance when the mold:
1. Before loading the mold to the upper and lower surface of the mold to clean, to ensure that the mold mounting surface and press work surface without crushing and mold in the production of the parallel installation surface parallelism;
2. After the mold is installed, the mold will be opened and the parts of the mold will be wiped clean, especially the guide mechanism. For the surface mold, the profile should be cleaned to ensure the quality of the parts.
3. Lubricate the sliding parts of the mold, apply grease;
4. Inspection of various parts of the mold, especially the safety parts. Such as: safety side sales, safety screws, side guards, punching waste Road and so on.
B, the production of maintenance:
1. The production of the corresponding part of the mold on a regular basis oil. Such as: pull the mold of the press ring, rounded; trimming die of the knife-edge parts; flanging knife part;
2. Regularly clean up the waste of the small hole waste road of the trimming punching mold.
C, after the maintenance of production:
1. After the end of the production of a comprehensive inspection of the mold;
2. A comprehensive cleaning of the mold to ensure that the mold cleanliness;
3. Clean the waste in the mold to ensure that there is no waste in the waste box;
4. The use of the mold and the use of the situation after the truth feedback to the "mold use work voucher" on.
Mold two maintenance:
The secondary maintenance of the mold refers to the regular maintenance of the mold based on the technical state and the complexity of the mold. The maintenance work is done by the repair staff and is recorded according to the maintenance situation. The following describes the different requirements and methods of the two parts:
A, drawing die punch, die:
The main problem of the convex and concave die of the drawing die is the pressure pit of the knitting and the profile, and the main part of the mold is polished. If there is pressure pit to repair the mold, and then repair;
B, guided parts (guide column, guide sleeve and guide, etc.):
Mold in the work will appear pull marks and other phenomena. The main reasons for the occurrence of lubricating oil dirty and guide the gap and so on. Guide parts to produce drawing marks, take the use of oil stone push the way after the polishing method to eliminate;
C, trimming edge:
Mold in the course of the use of the blade edge prone to chipping and edge collapse phenomenon, this time to damage the mold parts of the repair welding;
D, spring and other flexible parts:
In the course of use, the spring is one of the most vulnerable parts of the mold, usually the phenomenon of fracture and deformation. The method is to replace the replacement, but the replacement process must pay attention to the spring specifications and models, spring specifications models through the color, diameter and length of the three to determine, only in the three cases are the same circumstances can be replaced;
E, punch, punch sets:
Mold used on the punch, punching most of the standard parts are used, the mold in the course of the punch prone to break, bend and bite the wrong phenomenon, punch sets are generally bite bad. Punch and punch sets of damage are generally the same specifications of the parts to be replaced. Punch the main parameters of the working part of the size, installation part of the size, length size;
F, Fastening parts:
Check whether the fastening parts are loose or damaged. The way is to find the same specifications of the parts to be replaced;
G, press and unloading parts:
Pressure parts such as pressing plate, gifted plastic, such as unloading parts such as unloading board, pneumatic materials, such as the first device. Maintenance Check the assembly of the various parts of the damage, the damaged part of the repair. Check whether the aerodynamic roof material leakage phenomenon, and to take specific measures to the situation. Such as tracheal damage to replace and so on.
