[0031] Working principle:

[0032] Before using the device, first check the device components to ensure that the device components are properly matched and that the device can work normally.

[0033] When using the device, the user first starts the device and powers on and ventilates all components of the device. When the user needs the device to work, the user places the cut alloy strip of the desired width into the device through the feeding assembly 2. When the right-angle motor 205 starts working, the right-angle motor 205 drives one of the rotating rods 203 to rotate, which in turn drives the other rotating rod 203 to rotate through the two gears 204. When both rotating rods 203 rotate, the upper and lower rows of feeding wheels 202 rotate to feed the cut alloy strip into the bending die structure 1. After the alloy strip is inserted into the clamping assembly 3 through the bending die plate 104, the telescopic cylinder 302 is ventilated to promote the telescopic cylinder 302 to work, and the clamping head 303 clamps the alloy strip.

[0034] After clamping is completed, the feeding assembly 2 stops working and no longer feeds the alloy strip. The hydraulic telescopic rod 109 is started to push the sliding plate 107 to slide on the first sliding rod 105, compressing the first spring 106. The movement of the sliding plate 107 drives the bending plate 111, the bending head 112, and the cutting knife 113 to move. When the bending head 112 cooperates with the bending die plate 104, the alloy plate covering the bending die plate 104 is extruded into the shape of the bending head 112. When the alloy plate deforms, the feeding housing 201 is driven to slide on the two second sliding rods 207, compressing the second spring 208. The hydraulic telescopic rod 109 continues to work, causing the cutting knife 113 to contact the alloy plate, and the cutting knife 113 divides the already bent alloy plate. After division is completed, the device is reset, the user removes the cut clasp spring, and the device repeats the work again to achieve multi-station and batch production.

[0035] The bending die structure 1 can realize batch production of the clasp spring and increase the production efficiency of the clasp spring. Meanwhile, the feeding assembly 2 can realize automatic feeding of the raw material and pre-rolling of the raw material while feeding, avoiding bending of the raw material.

[0036] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various changes and modifications to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
