Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment tooling, and more specifically, to a heat treatment tooling for spring steel. Background Art

[0002] In the existing technology, the existing heat treatment tooling lacks a mechanism that can rotate the spring. During the heat treatment process, uniform heating of the spring is very critical because uneven heating may cause inconsistent properties of the metal, affecting the elasticity and life of the spring. The lack of a rotation mechanism means that some parts of the spring may be overheated or underheated due to uneven heat distribution, which will cause the mechanical properties of the finished product to fail to meet strict industrial standards.

[0003] Secondly, existing equipment lacks effective height adjustment and limit fixing mechanisms when processing springs of different heights. This deficiency limits the equipment's ability to handle springs of different specifications, increases the complexity of operation, and may require additional physical adjustments or multiple sets of tooling, thereby reducing production efficiency and increasing costs.

[0004] In addition, there are also problems with the rapid fixing of the abutment disk, which is a key part used to support and fix the spring. Rapidly and reliably fixing the abutment disk during the heat treatment process is crucial to ensuring the efficiency and safety of the entire heat treatment process. The existing tooling is unable to quickly complete the fixing of the spring, which may cause delays on the production line, increase the labor intensity of the operation, and may affect the safety of the staff.

When the retaining plate 12 needs to be released, the threaded sleeve 16 is manually pressed to make it move along the movable rod 18, thereby completing the extrusion process of the tension spring 19. At this time, the ball 21 moves to the limiting groove 22 on the threaded sleeve 16, and the limiting process of the fixing rod 15 is released. At this time, the fixing rod 15 is taken out, thereby releasing the limiting process of the spring. When the cylinder 8 is started to drive the fixing plate 10 and the fixing sleeve 11 to move to the initial position, the spring can be taken out.
