Description

Technical Field

[0001] The utility model relates to the technical field of equipment cleaning, in particular to an automatic cleaning device for a hard alloy pressing and forming die. Background Art

[0002] Cemented carbide is a mixture of two or more metals and metals or non-metals that have been synthesized to a certain extent and has metallic properties. During the high-temperature pressing process, it is impossible to ensure that the raw materials are 100% converted into formed cemented carbide. Therefore, there will always be a trace amount of raw materials that remain in the mold cavity after the molded product is demolded, and continue to accumulate in the repeated pressing action of the mold until it reaches a certain amount, which will make the subsequent pressed cemented carbide products dirty, pollute their outer surface, and produce defective products. Therefore, it is necessary to solve the problem of timely cleaning the mold cavity of cemented carbide pressing molds during the pressing process.

[0003] At present, the common solution is mainly through manual intervention. When the mold is pressed repeatedly for a certain number of times, that is, before the critical point that the cemented carbide product will become dirty, the pressing is stopped, and the on-site staff uses a brush to manually clean the raw material residues in the mold cavity, and blows it clean with an air gun before resuming pressing. Although the manual intervention cleaning method can basically prevent the occurrence of dirty problems, it still has many shortcomings. First, the raw materials for cemented carbide pressing are mostly powdered particles. When workers brush off the bonding materials and blow them near the mold cavity, the raw materials will be diffused into the air in large quantities. If inhaled into the mouth and nose or blown into the eyes, it will cause harm to the human body. Even if the workers wear protective equipment, they are in this environment for a long time and are very likely to cause occupational diseases; secondly, the power source of cemented carbide pressing molds is a hydraulic device that weighs tons. Although induction gratings and other devices are generally installed in front of the mold to prevent safety accidents, there are still some safety hazards in manual cleaning of the mold cavity; finally, the difference in cemented carbide pressing process and raw materials makes the critical value of dirtiness fluctuate greatly. For some raw materials with severe bonding, frequent manual intervention and cleaning are required, so more staff are needed, which increases the company's labor costs. Utility Model Content
