Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing equipment, and in particular relates to a mechanical processing auxiliary device. Background Art

[0002] One of the most common mechanical processing is part stamping, which uses a die to press metal sheets into various plate-shaped parts and shell and container-like workpieces on a press. This type of forming process performed in a cold state is called cold stamping, or simply stamping. Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet material to deformation force in the die and deform it, thereby obtaining product parts of a certain shape, size and performance.

[0003] The die used for stamping is called a stamping die, or simply a die, which includes an upper die and a matching lower die. A die is a special tool for batch processing of metal sheets into the required stamping parts. When stamping the die, a lot of heat will be generated by the extrusion between the upper die and the lower die and the metal sheet. Automated stamping generally lasts for a long time, so it is necessary to cool the upper die and the lower die during the stamping of the die. The purpose of applying oil to the upper die and the lower die is mainly for lubrication and rust prevention, and secondly, it has the function of cooling the die. First of all, lubrication is to allow the parts to have better forming when stamping, and rust prevention is needless to say. A lot of heat will be generated when the die is stamped, and the parts can be properly cooled after oiling to protect the die.

[0004] In order to prevent the oil spraying mechanism from splashing to the outside when spraying oil on the lower mold and the surface of the parts, a baffle is usually set near the oil spraying mechanism to prevent the oil from splashing to the outside. However, it is found in practice that the oil stains on the baffle will accumulate more and more with the length of working time, and it needs to be cleaned. The existing methods are mostly manual cleaning, and manual cleaning requires the equipment to stop running, which reduces the production efficiency. Utility Model Content
