Description

Technical Field

[0001] This utility model relates to the field of seat spring processing technology, and more specifically, to a seat spring processing equipment capable of simultaneously processing into a circle from both ends. Background Technology

[0002] Early seat spring manufacturing relied heavily on manual labor, with workers using simple tools to bend and shape steel strips. This method was extremely inefficient; a skilled worker could only produce a small number of springs per day, making it difficult to meet the demands of large-scale production. Moreover, manual processing made it difficult to guarantee the dimensional accuracy and shape consistency of the springs, resulting in inconsistent product quality and making it difficult to meet stringent quality standards in high-end seat production.

[0003] To improve production efficiency and product quality, machining equipment is increasingly being applied to seat spring manufacturing. Some traditional equipment achieves basic forming of the steel bars, typically employing a single-end sequential processing method: bending one end of the spring before processing the other. This results in a lengthy processing time, which, in today's fast-paced production environment, struggles to meet the explosive growth in market demand, especially during peak order seasons when insufficient capacity becomes a significant problem.

[0004] Secondly, traditional equipment has limited automation. In the feeding stage, steel bars often need to be manually placed in designated positions, which not only increases the workload of workers but also makes it difficult to guarantee the speed and accuracy of manual feeding, easily leading to feeding deviations and affecting the accuracy of subsequent processing. The cutting process may also require manual assistance, making full-process automation impossible and hindering further improvements in production efficiency.

[0005] Furthermore, traditional equipment has poor compatibility with steel bars of different specifications. Since different seats have varying requirements for spring size and elasticity, traditional equipment often requires complex parameter adjustments or component replacements when processing steel bars of different specifications. For example, changing molds of different specifications or adjusting processing force not only increases production time costs but may also affect product quality due to improper adjustments, further increasing production costs.

[0006] In summary, existing seat spring processing equipment has shortcomings in processing efficiency, automation level, and adaptability to steel bars of different specifications. There is an urgent need to develop a new type of processing equipment to solve these problems and meet the market's demand for high-quality, high-efficiency, and diversified seat spring production. Therefore, this paper proposes a seat spring processing equipment capable of simultaneously processing round springs from two ends. Utility Model Content

[0007] In order to overcome the above-mentioned defects of the prior art, the present invention provides a seat spring processing equipment capable of simultaneously processing into circles from both heads, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a seat spring processing device capable of simultaneously processing into circles from both ends, comprising a machine base, a fixed plate mounted on the machine base, a feeding mechanism mounted on one side of the fixed plate, a cutting mechanism mounted on the other side of the fixed plate, a support frame mounted on the machine base, two bending components mounted on the support frame, two mutually cooperating clamping mechanisms mounted on the machine base, a receiving port provided between the two clamping mechanisms, a guide frame provided at one end of the receiving port, and a discharge port connected and cooperating with the receiving port provided on one side of the bottom end of the machine base.

[0010] Preferably, the cutting mechanism includes a second motor, a first crank, a first slider, a cutter, and a first slide rail. The second motor is mounted on a fixed plate, and the output end of the second motor is connected to the first crank.

[0014] The technical effects and advantages of this utility model are as follows:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As attached Figures 1-5 The illustrated equipment for processing seat springs into circles simultaneously from both ends includes a machine base 1, a fixed plate 2 mounted on the machine base 1, a feeding mechanism 3 mounted on one side of the fixed plate 2, a cutting mechanism 4 mounted on the other side of the fixed plate 2, a support frame 5 mounted on the machine base 1, two bending components 7 mounted on the support frame 5, two cooperating clamping mechanisms 6 mounted on the machine base 1, a receiving port 9 provided between the two clamping mechanisms 6, a guide frame 8 provided at one end of the receiving port 9, and a discharge port 10 connected and cooperating with the receiving port 9 provided on one side of the bottom of the machine base 1.

[0026] In practice, the steel strips used for processing seat springs are conveyed at a fixed distance by the feeding mechanism 3. After being conveyed to the designated position, the two clamping mechanisms 6 operate to clamp and fix the steel strips. The cutting mechanism 4 cuts the conveyed steel strips, and then the two bending components 7 operate synchronously to bend both ends of the cut steel strips into circles to form seat springs. The two clamping mechanisms 6 then release the finished product, allowing it to fall into the receiving port 9 under the action of gravity and be blocked by the guide frame 8. It is then discharged from the discharge port 10, achieving efficient processing at both ends and improving processing efficiency.

[0027] The feeding mechanism 3 includes a fixed base 301, a first motor 302, a main conveying wheel 303, a secondary conveying wheel 304, a first flow guiding component 305, and a second flow guiding component 306. The fixed base 301 is mounted on the fixed plate 2. The first motor 302 is mounted on the fixed base 301. The main conveying wheel 303 is mounted on the output end of the first motor 302. The secondary conveying wheel 304 is mounted on the fixed base 301 at the top of the main conveying wheel 303. The first flow guiding component 305 is provided on one side of the fixed base 301, and the second flow guiding component 306 is provided on one side of the first flow guiding component 305.

[0028] In practice, the steel bar is input into the second guide assembly 306 for left and right limit, and then enters the first guide assembly 305 for up and down limit, so that the steel bar is straightened. Then the first motor 302 runs, so that the main conveying wheel 303 and the auxiliary conveying wheel 304 convey the steel bar at a fixed distance. The height of the auxiliary conveying wheel 304 can be adjusted, so that the clamping distance between the main conveying wheel 303 and the auxiliary conveying wheel 304 can be adjusted to adjust the clamping force on the steel bar.

[0029] The cutting mechanism 4 includes a second motor 401, a first crank 402, a first slider 403, a cutter 404, and a first slide rail 405. The second motor 401 is mounted on the fixed plate 2. The output end of the second motor 401 is connected to the first crank 402. The first crank 402 is connected to the first slider 403, which is slidably mounted on the first slide rail 405. The cutter 404 is mounted on the end of the first slider 403.

[0030] In practice, the operation of the second motor 401 causes one end of the first crank 402 to be pulled and swing, which in turn causes the other end to push and pull the first slider 403. As the first slider 403 moves along the first slide rail 405, the cutter 404 can approach the steel bar and cut it, thus achieving automatic and rapid cutting.

[0031] The clamping mechanism 6 includes a base frame 601, a third motor 602, a second crank 603, a second slider 604, a second slide rail 605, and a clamping plate 606. The base frame 601 is mounted on the machine base 1. The third motor 602 is mounted on the base frame 601. The output end of the third motor 602 is connected to the second crank 603. The second crank 603 is connected to the second slider 604, which is slidably mounted on the second slide rail 605. The clamping plate 606 is mounted on the second slider 604.

[0032] There are two clamping mechanisms 6, and the clamping plates 606 in the two clamping mechanisms 6 have different structures. One clamping plate 606 has a groove on one side, and the other clamping plate 606 has a protruding structure on one side, and a triangular groove is provided on the protruding structure. The triangular groove and the groove are used to clamp the steel bar.

[0033] In practice, the operation of the third motor 602 causes the second crank 603 to drag the second slider 604 to move on the second slide rail 605, thereby causing the clamping plate 606 to move accordingly. This allows the two clamping mechanisms 6 to operate synchronously, bringing the two clamping plates 606 closer together to clamp and fix the steel bar. After the two ends of the steel bar are processed, the two clamping plates 606 separate, and the processed product can fall automatically.

[0034] The bending assembly 7 includes a fourth motor 701, a rotating head 702, a shaft 703, and a bending head 704. The fourth motor 701 is mounted on the support frame 5. The rotating head 702 is mounted on the output end of the fourth motor 701. The shaft 703 is coaxially mounted on the rotating head 702. The bending head 704 is provided on one side of the shaft 703.

[0035] In practice, the fourth motor 701 operates, causing the rotating head 702 to rotate. The steel strip between the bending head 704 and the shaft 703 is supported by the shaft 703, and the bending head 704 pushes it, thus bending the steel strip into a circle. When the two bending components 7 operate synchronously, the double-head synchronous processing into a circle is achieved, thereby improving processing efficiency.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
