Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of diaphragm spring production, in particular to a diaphragm spring quenching device. BACKGROUND

[0002] In the existing diaphragm spring quenching process, local quenching is a commonly used method, in which the induction heating technology is the preferred method due to its fast heating speed, high heating efficiency, and easy automation control. Currently, the induction heating method is to set an induction heating ring on the upper part of the diaphragm spring to locally heat the separation finger at the center of the diaphragm spring.

[0003] However, this existing induction heating method has many obvious defects, which seriously restricts the efficiency and quality of diaphragm spring quenching. First, the heat generated in the upper space of the induction heating ring cannot be effectively utilized when locally heating the diaphragm spring, resulting in waste of energy and increased production cost. Second, since the induction heating ring only heats the separation finger of the lower diaphragm spring, and needs to heat for a specified time to make the separation finger reach the quenching temperature, the entire heating process is relatively long. During the heating process, the diaphragm spring can only be processed one by one, and the space and energy of the heating equipment cannot be fully utilized, resulting in a limited number of quenched diaphragm springs per unit time and low quenching efficiency. SUMMARY

[0004] The purpose of the present application is to provide a diaphragm spring quenching device to solve the above-mentioned problems in the prior art.

[0005] The technical solution of the present application to solve the above technical problems is as follows: A diaphragm spring quenching device, comprising a workbench, a heating module, an induction heating ring, a lifting module, an upper layer bracket, a lower layer bracket, a mechanical arm, a water bath, and a storage pool, the two adjacent side walls of the workbench are respectively provided with a water bath and a storage pool, the workbench is provided with a heating module on the table top, the heating module is horizontally provided with an induction heating ring, the upper and lower parts of the induction heating ring are respectively provided with an upper layer bracket and a lower layer bracket, the upper layer bracket and the lower layer bracket are fixedly connected with the lifting module, and the workbench is provided with a mechanical arm on one side of the lifting module.

[0006] The present application has the following advantages: the present device can fully utilize the space of the induction heating ring, heat the diaphragm springs on the upper layer and the lower layer of the induction heating ring at the same time, improve the energy utilization rate, and stagger the heating of the diaphragm springs on the upper and lower layers to improve the quenching efficiency.

[0007] Based on the above technical solution, the present application can also be improved as follows.

[0008] Further, the lifting module comprises a base plate, a stand, a fixing ring, a rotating ring and a top plate, the bottom of the base plate is fixedly connected to the tabletop of the workbench, the stand is fixedly connected vertically on the disc surface of the base plate, the outer wall of the stand is horizontally fixedly sleeved with the fixing ring, the outer wall of the fixing ring is rotatably sleeved with the rotating ring, and the top end of the stand is horizontally fixedly connected with the top plate; the upper layer of the top plate is horizontally fixedly connected with the bracket; the outer wall of the rotating ring is horizontally fixedly connected with the lower layer of the bracket.

[0009] The further beneficial effect of the above is that by setting the base plate, the stand, the fixing ring and the rotating ring, when the mechanical arm pulls the lower layer of the bracket, the upper layer of the bracket and the lower layer of the bracket are dislocated, which facilitates the placement and grabbing of the diaphragm spring on the lower layer of the bracket.

[0010] Further, two limiting rods are arranged on the two sides of the base plate to limit the rotation stroke of the lower layer of the bracket, and when the lower layer of the bracket abuts against one of the limiting rods, the lower layer of the bracket is just located below the induction heating ring.

[0011] The further beneficial effect of the above is that the overstroke of the mechanical arm pulling the lower layer of the bracket is avoided, and the rotation accuracy of the lower layer of the bracket is improved. BRIEF DESCRIPTION OF DRAWINGS
