Description

Technical Field

[0001] The utility model relates to the technical field of spring punching processing, in particular to a spring punching processing device. Background Art

[0002] Constant force spring, also known as constant force spring, is a spring designed to provide almost constant force during tension or compression. Unlike traditional coil springs, the force generated by constant force springs during deformation changes very little, which makes it very useful in many applications that require stable force output. In traditional processes, the strip of constant force spring is first punched by a punch press and then wound by a CNC spring winding machine. However, the winding process after punching makes it difficult to ensure that the position of the punched holes corresponds to the designed position and size of the product. In addition, the winding process after punching makes the spring more susceptible to environmental factors such as temperature and humidity, thereby affecting the constant force characteristics.

[0034] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0036] See also Figure 1-12 In this embodiment, a spring punching processing device is provided, including: a base plate 1, a placement plate 101 is fixedly connected to the top of the base plate 1, a fixed plate 4 is fixedly connected to one side of the placement plate 101, and a bracket 3 is fixedly connected to the other side of the placement plate 101; a stamping assembly is provided on the top plate of the placement plate 101, and the stamping assembly includes: a top plate 201, a connecting rod 202, a pressing plate 203 and a stamping block 205; and a stretching assembly is provided on the fixed plate 4, and the stretching assembly includes: a chain 401, a fixed block 402, a mounting frame 5 and a sprocket 502.

[0037] Among them, through the coordinated design of stamping components and stretching components, the process is improved to first winding and then punching, and some processes are merged or simplified to improve production efficiency. At the same time, by precisely controlling the position of the punching, it can be ensured that the spring can evenly distribute stress when subjected to force, avoiding deformation or fracture caused by excessive local stress, and enhancing structural stability.

[0038] Example 2

[0039] On the basis of Example 1, four guide pillars 2 are connected to the top of the placement plate 101, and a top plate 201 is provided on the top of the guide pillar 2. Four openings are opened on the top plate 201, and the positions of the openings correspond to the guide pillars 2. Two through holes are opened on the top plate 201, and a connecting rod 202 is passed through the through holes. A pressing plate 203 is connected to the bottom of the connecting rod 202, and a slot 204 is opened on the pressing plate 203. A stamping block 205 is connected to the bottom of the top plate 201, and the bottom end of the stamping block 205 extends into the slot 204, and the cross-sectional size of the stamping block 205 matches the cross-sectional profile of the slot 204. Multiple return springs 206 are connected between the pressing plate 203 and the top plate 201, and a guide spring is provided on the outside of the guide pillar 2. The two ends of the guide spring are respectively connected to the placement plate 101 and the top plate 201. A stamping groove 102 is opened on the placement plate 101, and the position of the stamping groove 102 corresponds to the slot 204.

[0040] When punching the spring, the top plate 201 is pushed down by the external hydraulic rod, so that the top plate 201 drives the punching block 205, the connecting rod 202 and the pressing plate 203 to move down. In this process, the top plate 201 slides downward along the guide column 2 through the opening, so that the guide spring sleeved on the outside of the guide column 2 is squeezed and accumulates elastic force. Then the pressing plate 203 contacts the spring workpiece before the punching block 205. When the top plate 201 continues to move downward, the top plate 201 presses the return spring 206, causing the return spring 206 to elastically deform and generate elastic force, and the generated elastic force is applied to the On the pressing plate 203, the pressing plate 203 preliminarily presses and fixes the spring workpiece to ensure the subsequent punching accuracy, and the setting of the connecting rod 202 and the through hole can limit the moving direction of the pressing plate 203, and then the top plate 201 drives the punching block 205 to move downward to punch the spring workpiece. Through the setting of the punching groove 102, on the one hand, the waste generated by the punching can be discharged, and on the other hand, a punching space can be provided for the punching block 205; after the punching is completed, the top plate 201 and the pressing plate 203 can be reset by the setting of the reset spring 206 and the guide spring.

A sprocket 502 is connected to the outside of the rotating rod 501, and an auxiliary wheel 503 is fixedly connected to one end of the rotating rod 501.

[0043] When punching a spring workpiece, the wound spring workpiece is placed on the placement roller 301, and then the placement roller 301 is installed on the bracket 3. Then, one end of the spring workpiece is connected to the fixed block 402 of the chain 401 so that the chain 401 can pull the spring workpiece to unfold. When unfolding, one end of the chain 401 is engaged with the sprocket 502, and the auxiliary wheel 503 is used to drive the rotating rod 501 and the sprocket 502 to rotate, thereby driving the chain 401 to move backward and unfold the spring workpiece. Then, according to the position of the punching required, the unfolded spring workpiece is pulled to the appropriate position through the chain 401 for punching.
