Surface treatment method of die steel after molding

Abstract

The invention relates to a surface treatment method of die steel after molding. Oxide layer cleaning equipment is used and comprises a base plate, a shell and a cleaning device. The specific technological process for cleaning oxide skins on the surface of the die steel by adopting the oxide layer cleaning equipment comprises the following steps of equipment adjustment, die steel transferring, oxide layer cleaning, discharging and fragment collecting. The cleaning device comprises cleaning branch chains, connecting blocks, moving frames, telescopic rods, rotating cams, rotating rods and rotating motors, and the cleaning branch chains comprise top plates, extrusion blocks, cleaning brushes, linkage plates and inserting frames. According to the surface treatment method of the die steel aftermolding, the cleaning brushes can be driven to move back and forth in multiple directions during cleaning, so that the purposes of expanding cleaning ranges and reducing cleaning dead angles are achieved, the cleaning brushes are of detachable combination structures, and the cleaning brushes with long-time use are convenient to clean and parts are convenient replace.

Description

technical field [0001] The invention relates to the technical field of die steel surface treatment, in particular to a surface treatment method for mold steel after forming. Background technique [0002] Die steel is a type of steel used to make molds such as cold stamping dies, hot forging dies, and die-casting dies. In the production process of die steel, the surface will form an oxide film-iron oxide scale due to oxidation, and the oxide layer needs to be cleaned before it is put into use. The following questions: [0003] a. When cleaning the oxide layer, the cleaning brush is often driven to reciprocate on the surface of the mold steel by automated equipment or manually to peel the oxide layer from the surface of the mold steel. Since the bristles on the cleaning brush are in a fixed position, it is impossible to ensure that the mold steel Every part of the surface is in full contact with the bristles, which is prone to incomplete cleaning; [0004] b. After the clea...

Problems solved by technology

[0003] a. When cleaning the oxide layer, the cleaning brush is often driven to reciprocate on the surface of the mold steel by automated equipment or manually to peel the oxide layer from the surface of the mold steel. Since the bristles on the cleaning brush are in a fixed position, it is impossible to ensure that the mold steel Every part of the surface is in full contact with the bristles, which is prone to incomplete cleaning;

[0004] b. After the cleaning brush has been used for a long time, the oxide layer debris peeled off from the surface of the mold steel is easy to adhere to the bristles, so it is necessary to clean the bristles in time or replace the cleaning brush regularly. Frequent replacement of the cleaning brush will inevitably increase the operation of the manufacturer The cost and economy are poor, and when cleaning the bristles, due to the large number of bristles and small diameter, it is difficult to completely remove the debris on the bristles with conventional cleaning tools, and the remaining debris will be cleaned in the subsequent oxide layer During the process, it moves synchronously with the cleaning brush, thereby wearing down the surface of the mold steel
