Description

Technical Field

[0001] The utility model relates to the technical field of quenching devices, in particular to a quenching device for spring production. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. A part made of elastic material deforms under the action of external force and returns to its original shape after the external force is removed. It is also called a spring.

[0003] The existing spring quenching operation generally places multiple springs in a quenching box, and uses the coolant in the quenching box to achieve the quenching function of the springs. Since the multiple springs are in a static state in the quenching box, there is a stacking phenomenon between the springs, resulting in an insufficient cooling effect of the springs. In addition, as the quenching operation proceeds, the temperature of the coolant gradually rises and the cooling effect decreases, so it is necessary to wait for the coolant to cool before the next quenching operation can be performed, which reduces the spring quenching efficiency. Therefore, a quenching device for spring production is proposed to solve the above problems. Utility Model Content

A quenching device for spring production is proposed.
