Description

Technical Field

[0001] The utility model relates to the technical field of glasses frame processing, in particular to a glasses mould heat treatment device. Background Art

[0002] Heat treatment refers to a metal thermal processing technology that uses heating, heat preservation and cooling to obtain the desired structure and performance of materials in the solid state. In the process from the Stone Age to the Bronze Age and the Iron Age, the role of heat treatment has gradually been recognized by people.

[0003] After the stamping mold of glasses is manufactured, since its material is relatively soft, the mold is very easy to wear during production and use. Therefore, the stamping mold needs to be heat treated to increase the hardness and wear resistance of the stamping mold.

[0004] In the heat treatment work of the stamping die, the existing heating furnace and the furnace door are mostly fixed by providing a lock key on one side of the furnace door, which can be inserted into the lock hole on one side of the heating furnace for fixation. The heating furnace will generate a lot of heat when working. The lock key may soften under long-term calcination, resulting in the furnace door cannot be opened. The furnace door is inconvenient to open and close, which easily affects the production efficiency, so it needs to be improved. Utility Model Content

[0007] Preferably, sealing rings are provided at both ends of the furnace door.

[0008] Preferably, the two sealing rings are fixedly connected to the heating furnace.

[0009] Preferably, fixed handles are fixedly connected to both ends of the right side of the front end of the furnace door.

[0010] Preferably, a limiting rod is fixedly connected between the middle and right sides of the front ends of the two adjacent slide slot plates.

[0011] The beneficial effects of the utility model are as follows:

[0012] The utility model discloses that the furnace door can be attached to the heating furnace by rotating the rotating plate in the clamp seat, which improves convenience. The control handle is pushed to insert the connecting plate into the fixing groove on the fixing block. The connecting plate and the fixing block are limited and fixed by inserting the insertion rod into the insertion hole and the limiting groove, thereby replacing the traditional lock key fixation and solving the problem that the heating furnace generates a large amount of heat during operation and the lock key is softened due to long-term calcination, thereby causing the furnace door to be unable to be opened. The plug-in relationship between the insertion rod and the limiting groove further ensures the stability of the connection between the fixing strip and the fixing buckle, thereby ensuring a good fixing effect on the heating furnace.
