Description
Technical Field
The invention belongs to the field of cold heading dies, and particularly relates to a method for quickly positioning and replacing a bottom die.
Background
At present, cold heading equipment in fastener production uses manpower to put a die in when changing the die, and is adjusted by oneself. Sometimes, due to the fact that production arrangement needs to be changed frequently, due to the fact that changing time is too long, and the investment of personnel needs to be increased. Resulting in longer production period and great labor loss. Particularly, the profit is reduced for tasks of various varieties and small batches.
The problem of mold replacement is solved by improving a mold replacement method, so that the mold can be rapidly replaced, the product precision needs to be ensured, and the mold is safely and firmly installed.
Summary of the existing production problems:
1. the traditional die change process needs manual operation through observation, is complex in installation, wastes time and labor, and has great potential safety hazards.
2. Workers move around to find and take tools, materials and the like, and much time and labor cost are wasted.
3. The traditional die change process has long and complicated die change time and seriously influences the production efficiency and the machine utilization rate.
4. The traditional die change process is easy to cause die damage and has large potential safety hazard.
With the increasing market competition, fasteners are updated more and more quickly, stock varieties are more and more, the conditions of multiple varieties, medium and small batches and mixed flow just-in-time production in production become mainstream, and particularly, for enterprises matched with the automobile industry, for example, fasteners are taken as examples, and qualified products are required to be provided for different automobile models in parallel and just in time. Therefore, the interval time of the die replacement is shorter and shorter, namely, the frequency of the die replacement is higher and higher, the downtime of the corresponding cold header is greatly increased, the production efficiency and the machine utilization rate are seriously influenced, the delivery cycle is prolonged, and the large investment cannot be effectively returned.
The current situation arouses the attention of manufacturers for producing and using the cold heading machine in China, and if the problem of rapid die change is not effectively solved in cold heading processing automation, the automation degree of other production links is higher, so that the utilization rate of equipment and the production efficiency are difficult to be fully improved. This problem has been substantially solved in industrially developed countries, namely: a rapid die change system is employed. The quick die changing system has strong practicability and wide application range, can be used for various cold heading machines of companies, is not available for quick die changing equipment, and a skilled worker needs to complete die changing within 7-8 hours, thus occupying too long working time. If the rapid die changing equipment is adopted, the fast die changing equipment only needs to occupy about 20 minutes on line, and other work can be finished under the line, so that the production efficiency is greatly improved. The quick replacement mechanism can greatly improve the production efficiency of the fastener industry.
