【Summary】 Inspection of fitting accuracy of explosion-proof sleeves. The main method of detection is to insert the square tenon of the explosion-proof sleeve accessory into the connected square hole five consecutive times, and then lift the square tenon sleeve to prevent it from falling off. The various components of the explosion-proof sleeve should be closely coordinated with each other, and they should be flexible in assembly and disassembly. The copper alloy anti dislocation beads and pins should not fall off.

Inspection of fitting accuracy of explosion-proof sleeves. The main method of detection is to insert the square tenon of the explosion-proof sleeve accessory into the connected square hole five consecutive times, and then lift the square tenon sleeve to prevent it from falling off. The various components of the explosion-proof sleeve should be closely coordinated with each other, and they should be flexible in assembly and disassembly. The copper alloy anti dislocation beads and pins should not fall off.
Hardness test for explosion-proof socket wrenches. The hardness of explosion-proof sleeves should be tested based on the fact that when the size of the hexagonal or twelve corner opposite sides of the sleeve is less than or equal to 32mm, the hardness of aluminum bronze explosion-proof sleeve wrenches should be greater than 25 HRC, and the hardness of beryllium bronze explosion-proof sleeve wrenches should be greater than 35 HRC. The hardness of a normal steel sleeve should be 39-48HRC, and the hardness should be 35-44HRC when the size of the hexagonal or twelve corner opposite sides of the sleeve is greater than 32mm and less than or equal to 55mm.
Inspection standards for explosion-proof socket wrenches. The inspection of explosion-proof socket wrenches focuses on the explosion-proof performance of the wrenches. As one of the explosion-proof tool wrenches, explosion-proof socket wrenches are mainly used when the position of nuts or bolts is limited by various spaces, and ordinary wrenches cannot work properly. This explosion-proof socket wrench needs to be used. The wrench for explosion-proof sleeve must pass the testing of explosion-proof tool performance friction testing machine, drop hammer testing machine, impact testing machine, etc.
The components of explosion-proof sleeves mainly include handles, joints, and various sizes of sleeve heads. The specifications of explosion-proof sleeves generally include 9-piece sets, 13-piece sets, 17-piece sets, 24-piece sets, 28-piece sets, and 32-piece sets.
