Description

Technical Field

[0001] This utility model belongs to the field of spring processing technology, specifically relating to a spring forming device. Background Technology

[0002] Springs are important components widely used in electronics, electrical appliances, and machinery. Their main function is to achieve precise control of pressure, vibration, or contact through their own elastic deformation. Springs play a crucial role in various devices, such as circuit switches, touch buttons, and pressure regulating mechanisms in some mechanical devices. With the development of technology, the application fields of springs are constantly expanding, and higher requirements are being placed on the processing quality and production efficiency of springs.

[0003] Currently, traditional spring production processes typically employ manual or semi-automated methods, which present several problems. First, manual operation suffers from low accuracy, easily leading to dimensional errors or poor forming, affecting the spring's performance and lifespan. Second, traditional production equipment usually only completes some processing steps, such as cutting or bending, requiring multiple processes to ultimately form the spring. This not only increases production complexity but also reduces efficiency. Third, the transfer of materials between multiple steps incurs additional time costs and material waste, failing to meet the demands of modern industry for efficient and automated production.

[0004] To address the aforementioned issues, some existing automated spring forming equipment has emerged, but it still possesses certain limitations. For instance, some equipment lacks precise control during material conveying, leading to material misalignment during forming and affecting the consistency of the finished product. Furthermore, the coordination between different mechanisms during forming is not smooth enough, easily causing jams or malfunctions in production and reducing efficiency. Therefore, designing a highly efficient, precise, and fully automated spring forming device has become a pressing issue for the industry. Utility Model Content

[0036] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0037] Example 1

[0038] Please refer to Figure 1-9 This embodiment provides a spring forming device, including a mold base 1, which serves as the supporting foundation for the entire device. Various functional components are mounted on the mold base, including a feeding mechanism 2, a forming mechanism 3, a stamping mechanism 4, and a conveying mechanism 5. The mold base 1 possesses good mechanical strength and rigidity, ensuring the stability and accuracy of each mechanism during operation. The dimensions of the mold base 1 can be customized according to specific production needs, and it is typically made of high-strength steel or cast iron to ensure that it will not deform or wear during prolonged use.

[0039] The feeding mechanism 2 includes a feeding seat 21 and a feeding port 22. The spring material 6 enters the device through the feeding port 22. A transition roller 23 is provided at the feeding port to facilitate the smooth entry of the material into the processing area.

[0040] In this embodiment, the feed seat 21 can be driven by a lead screw module or a telescopic cylinder to move horizontally along the slide bar 24, moving closer to or further away from the stamping mechanism 4, thereby adjusting the feeding process to accommodate materials of different specifications.

[0041] The main function of the feeding mechanism 2 is to ensure that the material is continuously and evenly conveyed to the stamping mechanism 4 and the forming mechanism 3, thereby ensuring the efficiency and consistency of subsequent processing.

[0042] In this embodiment, the stamping mechanism 4 is located between the feeding mechanism 2 and the forming mechanism 3, and is used for pre-processing or preliminary processing of materials. The stamping mechanism includes a stamping platform 41, a stamping die 42, and a telescopic cylinder 43 that drives the stamping die to move up and down. The stamping platform 41 is used to place the material to be stamped, and the stamping die 42 moves vertically under the action of the telescopic cylinder 43 to perform stamping, forming, or punching operations on the material.

[0043] The telescopic cylinder 43 is fixed on the mold base 1 and controls the movement of the stamping die by air or hydraulic pressure. It has high control precision and can be flexibly adjusted according to different specifications of the spring material 6 to ensure the accuracy and consistency of the stamping effect.

[0044] The forming mechanism 3 is the core component of this device, responsible for precisely bending and shaping the stamped spring sheet material 6. This mechanism includes a core 31 and several forming parts, which are arranged circumferentially around the core 31. The core 31 can extend and retract on the surface of the mold base 1. When the core 31 extends beyond the surface of the mold base 1, it cooperates with the forming parts for shaping; when the core 31 retracts into the mold base 1, it is used for unloading the spring sheet product.

[0045] One end of the core 31 is provided with a connecting rod 311, and the end of the connecting rod 311 away from the core 31 is provided with a limiting rod 312. A first cam 313 is provided on one side of the limiting rod 312. The first cam 313 is fixed on a rotating rod 314, which is mounted on a fixed platform and driven to rotate by a motor, thus pushing the connecting rod 311 to move. The connecting rod 311 can also be provided with a return spring, so that after the first cam 313 leaves the limiting rod 312, the connecting rod 311 can automatically return to its original position, thereby realizing the retraction of the core 31. Of course, the core 31 can also be detachably mounted on the connecting rod 311, so as to perform different molding operations according to the size and shape requirements of the spring sheet.

[0046] The molded part includes a cutting part 33, a limiting part 34, and several bending parts 35. The end shape of the bending part 35 is consistent with the outer surface of the core 31. The bending part and the core cooperate to press the spring material 6 into a predetermined shape. The cutting part 33 is used to cut the spring material 6. The cutter of the cutting part 33 is set vertically and cuts the spring material 6 downwards. The limiting part 34 plays a fixing and positioning role to ensure the accuracy of bending and cutting operations and prevent the spring material 6 from jumping out.

[0047] During molding, after the spring material 6 is transported above the core 31, the cutter of the cutting part 33 moves downward to cut the spring material 6. After the limiting part 34 presses the spring material 6, the bending part 35 moves to bend the spring material 6 into shape. The cutting part 33, the limiting part 34 and several bending parts 35 are reset. After the core 31 is quickly retracted under the action of the spring, the molded product is quickly unloaded.

[0048] The molded part is driven by a drive mechanism 32 to reciprocate relative to the core 31. The drive mechanism includes a slide block 321 with a slider 322 on it. The molded part is fixed at one end of the slider 322, and the other end engages with a second cam 324 via a protrusion 323. The second cam 324 is connected to a rotating shaft 325 and is driven to rotate by a rotating mechanism, pushing the slider to move along the slide block 321, thereby realizing the reciprocating motion of the molded part. A return spring can be installed inside the slider 322. When the second cam 324 leaves the protrusion 323, the slider 322 can drive the molded part to return to its original position under the action of the spring's return force.

[0049] The slide block 321 and slider 322 in the drive mechanism 32 provide a stable moving track for the molded part. The movement of the slider is driven by the second cam 324, which is connected to the rotating shaft 325 and driven by the rotation mechanism. In this embodiment, the movement of the molded part and the core 31 is controlled by the cam. The movement trajectory and time are adjusted by setting the shape of the cam to accurately mold the spring material 6 and ensure that the shape and quality of the finished product meet the requirements.

[0050] Example 2

[0051] Please refer to Figure 5-7 This embodiment is based on embodiment 1. By further configuring the structure of the rotating mechanism and the conveying mechanism 5, the continuity of product production is improved. Specifically:

[0052] The rotating mechanism consists of a driving pinion 326, a driven large gear 327, and several driven pinions 328. Power is transmitted through the meshing of the gears. The pinions are driven by a motor, causing the molded part to reciprocate along the slide block 321. The driving pinion 326 is driven by a motor.

[0053] The driving pinion 326 is connected to the rotating shaft 325 of one of the molded parts, and several driven pinions 328 are connected to the remaining molded parts, ensuring that the molded parts move synchronously. By simply setting the cam shape, the molding process of cutting and bending can be realized, ensuring that the shape and quality of the finished product meet the requirements.

[0054] The conveying mechanism 5 is used to transport the spring sheet material 6 from the feeding mechanism to the stamping mechanism 4 and the forming mechanism 3. The conveying mechanism 5 includes a conveyor belt 51 with a material trough 52 for receiving the material to ensure that the material does not shift or slip during the conveying process. A cover plate 53 is also provided above the conveyor belt to protect the material from external contamination and prevent the material from falling off.

[0055] The conveyor belt 51 is controlled by a servo motor and can adjust the conveying speed according to the processing speed to ensure seamless connection of each processing step and improve the production efficiency of the entire device.

[0056] In actual operation, the spring sheet material 6 first enters the device through the feeding mechanism and is then conveyed to the stamping mechanism 4 for preliminary processing. Subsequently, the material enters the forming mechanism, where the core 31 and the forming part cooperate to press and bend the material. The cutting part 33 then precisely cuts the spring sheet material to ensure that the size of each spring sheet meets the predetermined requirements.

[0057] During the cutting and bending process, the limiting component 34 plays a fixing role, preventing the material from shifting or deforming during processing. At the same time, the reciprocating motion of the forming part ensures that every part of the material is uniformly bent, ultimately forming a spring sheet that meets the specifications.
