Description

Technical Field

[0001] This utility model relates to the field of mold steel processing technology, specifically a cleaning device for a mold steel shot blasting machine. Background Technology

[0002] In the production of mold steel, as a key steel grade for manufacturing molds such as cold stamping dies, hot forging dies, and die casting molds, its quality has a crucial impact on the quality of pressure processing, product precision, output, and production costs. However, in the processing of mold steel, especially in heat treatment and forging stages, a large amount of oxide scale easily forms on its surface. If this oxide scale is not thoroughly removed, it will become trapped inside the steel during subsequent processing, seriously affecting the quality of the mold steel. To solve this problem, shot blasting machines are widely used for removing oxide scale from the surface of mold steel. Shot blasting machines use a high-speed rotating impeller to propel shot at the surface of the mold steel, efficiently removing oxide scale through the impact force of the shot. Compared to the traditional manual removal method using steel brushes, this greatly improves production efficiency and reduces the labor intensity of workers. However, existing mold steel shot blasting machines still reveal many problems that urgently need to be solved in actual use.

[0003] To address the aforementioned issue of shot cleaning in shot blasting machines, Chinese Patent Publication No. CN222986698U discloses a cleaning device for mold steel shot blasting machines. This device includes a collection hopper, with a cleaning chamber connected below the hopper. An air blower is mounted on the side of the cleaning chamber, and a collection guide groove for collecting shot fragments and impurities is positioned opposite the air blower. A guide pipe connects to the bottom of the cleaning chamber, and an air duct is connected to the guide pipe. A second air blower is mounted at the bottom of the air duct, and a magnetizing device is installed above the second air blower at the end of the air duct. A magnetic strip is mounted on the side of the middle section of the air duct, and a second collection guide groove for collecting shot is positioned opposite the magnetic strip. The top of the air duct connects to an external recovery pipe. This invention, through the combination of air and magnetic separation structures, effectively removes shot fragments and impurities from the shot during the shot blasting process, ensuring the shot's reusability.

[0004] The above-mentioned solutions propose using air separation and magnetic separation structures to effectively remove fragments and impurities from the shot during shot blasting. However, these solutions rely on direct filtration via a fan and magnetic force applied to the shot, resulting in poor filtration. Larger, higher-quality impurities, or those of the same material as the shot, may remain in the shot, which the existing screening methods cannot effectively remove. This leads to a decline in cleaning quality and negatively impacts subsequent mold steel processing. Therefore, we provide a cleaning device for mold steel shot blasting machines.
