Description

Technical Field

[0001] This utility model relates to the field of gasket heat treatment technology, specifically to an anti-deformation device for heat treatment of flat washers. Background Technology

[0002] Flat washers are typically thin components of various shapes used to reduce friction, prevent leaks, isolate, prevent loosening, or distribute pressure. They are found in many materials and structures, performing similar functions. Due to material and manufacturing limitations of threaded fasteners, bolts and other fasteners have small bearing surfaces; therefore, washers are used to reduce compressive stress on the bearing surface and protect the surfaces of the connected parts.

[0003] The heat treatment process for flat washers is a crucial step in improving their hardness and strength. The specific heat treatment process involves heating the flat washer to 920℃ and holding it at that temperature for 35 minutes, then rapidly cooling it in brine, followed by air tempering at 300℃ for 2 hours. This significantly improves the hardness of the flat washer, thus better meeting the needs of engineering applications. However, currently, during the heat treatment of flat washers, they are generally placed loosely into the quenching furnace. This makes the flat washers prone to deformation upon heating, requiring subsequent manual re-correction.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0005] To address the above deficiencies, this utility model provides an anti-deformation device for heat treatment of flat washers, thereby solving the problem of preventing deformation during heat treatment of flat washers.

[0008] The hoisting mechanism includes a rectangular shell, a drive motor, a fixed frame, a reciprocating screw, a reciprocating screw nut, a lifting plate, a guide rod, a rotating shaft, a rotating sleeve, a bearing plate, several bearing rods, and a fixed top plate. The rectangular shell is installed at the center of the upper end of the sealing cover. The drive motor is installed inside the rectangular shell on the left side, with its rotating end facing vertically upward. The fixed frame is installed on the rear wall of the sealing cover. The reciprocating screw is movably inserted into the center of the fixed frame. The reciprocating screw nut is movably fitted onto the reciprocating screw. The lifting plate is fixedly connected to the outside of the reciprocating screw nut.
