Description

Technical Field

[0001] This invention belongs to the field of automotive parts processing technology, and more specifically, relates to an automotive seat spring bending and forming device. Background Technology

[0002] A bending device is a mechanical device used to bend metal sheets or pipes. It causes the metal material to bend and deform by applying pressure and force. It is widely used in the metal processing industry, such as in the manufacture of metal components, pipes, and car body parts. Bending devices can adopt different structures and principles according to different needs and process requirements. These devices play an important role in the manufacturing industry, improving production efficiency and processing quality.

[0003] 1. In the existing equipment, two fixed limit pins are usually used to limit the spring material extending from the bending device before the bending motor drives the bending pins to bend the spring material. However, depending on the process requirements, the spring material usually has different heights. When bending spring material with different heights, the existing equipment usually requires replacing the limit pins, which cannot be adjusted. This is cumbersome to use and its applicability needs to be improved.

[0004] 2. When using the existing device to process spring materials of different diameters, due to the different spacing, it is usually necessary to replace the entire limiting module to limit the spring materials. It cannot adjust the limiting pins, making it cumbersome to use and its applicability needs to be improved.

[0005] 3. When using the existing device, depending on the different processing requirements and the varying sizes of the spring raw materials, the limit module usually needs to be disassembled. Furthermore, since the limit module is often connected by screws, multiple screws need to be removed and installed during replacement, making it impossible to adjust the limit module and causing inconvenience in use. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides an automotive seat spring bending and forming device.

[0007] A bending and forming device for automotive seat springs includes a bending and forming device body, a processing shaft on the side wall of the bending and forming device body, a connecting rod on the side wall of the processing shaft, a bending motor fixedly installed inside the connecting rod, an outer ring fixedly installed on the output shaft of the bending motor, a plurality of bending pins fixedly installed on the upper end of the outer ring, and a first through groove, a second through groove and a third through groove respectively opened on the circumferential surface of the outer ring;

[0008] An adjustable mechanism is fixedly installed at the upper end of the bending motor;

[0009] The adjustable mechanism includes an inner ring, which is rotatably mounted inside the outer ring. A first sliding groove is formed inside the inner ring, and a dust collection groove and a square groove are respectively formed through the inner wall of the first sliding groove. A second sliding groove is formed inside the inner ring, located above the first sliding groove and communicating with it. A third sliding groove is formed through the side wall of the second sliding groove. The dust collection groove, square groove, and third sliding groove are parallel to the third through groove, the second through groove, and the first through groove, respectively. The adjustable mechanism also includes a threaded rod, a fixed block, a driven bevel gear, a synchronous belt, a driving bevel gear, a threaded block, a first drain groove, a fixed column, a support box, a fourth sliding groove, a second drain groove, a bidirectional lead screw, a transmission block, a limit pin, a slotted head, and a third drain groove.

[0010] Preferably, the threaded rod is rotatably installed inside the square groove, the fixing block is fixedly installed on the inner circumferential surface, the fixing block is located below the square groove, the driven bevel gear is rotatably installed above the fixing block, and the timing belt is rotatably installed between the threaded rod and the driven bevel gear, with the timing belt located at the square groove.

[0011] Preferably, the driving bevel gear is rotatably mounted on the inner ring circumferential surface, the driving bevel gear meshes with the driven bevel gear, a slot is formed on the rotating column of the driving bevel gear, the threaded block is threadedly mounted on the threaded rod circumferential surface, the threaded block is slidably mounted with the first sliding groove, each of the first slots is formed through the inside of the threaded block, the two fixed posts are fixedly mounted on the upper end of the threaded block, the two fixed posts are partially exposed inside the second sliding groove, and the two fixed posts are slidably mounted with the inner ring.

[0012] Preferably, the support box is fixedly installed between the fixed columns, the support box is slidably installed with the second slide groove, the fourth slide groove is opened inside the support box, each of the second slots is opened through the lower part of the fourth slide groove, the bidirectional lead screw is rotatably installed inside the fourth slide groove, the bidirectional lead screw is partially exposed outside the third slide groove, and the two transmission blocks are threaded on the circumferential surface of the bidirectional lead screw.

[0013] Preferably, both transmission blocks are slidably installed inside the fixed block, both limiting pins are fixedly installed at the upper end of the transmission blocks, the I-shaped head is fixedly installed on the side wall of the bidirectional lead screw, and each of the third slots is opened through between the top of the first slot and the bottom of the second slot.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, when a worker picks up a flathead screwdriver and inserts it into the slot on the driving bevel gear to rotate, the flathead of the screwdriver generates a radial force that drives the driving bevel gear to rotate on the inner ring and mesh with the driven bevel gear. This causes the driven bevel gear to rotate on the fixed block. At the same time, the timing belt drives the threaded rod to rotate and engages with the threaded block through threaded transmission. This causes the threaded block to move the fixed column upward in the first slide groove, thereby pushing the support box upward. As the support box rises, the distance of the limit pin exposed above the outer ring increases, allowing the height of the limit pin to be adjusted according to the size of the spring material being processed, thus improving applicability.

[0016] In this invention, when a worker picks up a flathead screwdriver and inserts it into the flathead through the first through slot to rotate it, the flathead will generate a radial force that drives the bidirectional lead screw to rotate in the fourth slide groove within the support box. This causes the bidirectional lead screw to engage in threaded transmission with the transmission blocks, which in turn causes the two transmission blocks to move the limiting pins away from or towards each other in the fourth slide groove. This adjusts the distance between the two limiting pins, thus adapting to spring materials of different sizes and further improving applicability.

[0017] In this invention, when the bending and forming device body finishes processing a spring, the cutting blade of the bending and forming device body will cut the part. However, after the cutting blade cuts the spring, some powder will fall into the second chute. By setting the first chute, the second chute, and the third chute, the operator can use an air gun to blow the powder in the inner ring into the bottom of the first chute. The operator only needs to insert the vacuum cleaner head into the vacuum chute and start it to clean the powder in the inner ring, avoiding the accumulation of powder in the inner ring that may jam the movement of the adjustable mechanism and improving the stability of the device.

[0018] In this invention, when the height of the limiting pin and the spacing between the limiting pins are adjusted, the threaded block will move upward in the first slide groove and indirectly push the limiting pin to rise. When the bidirectional lead screw and the transmission block are driven by threads, the transmission block will slide in the fourth slide groove, thereby increasing the additional limit and improving stability.

[0019] In this invention, by setting the square groove and the third sliding groove parallel to the second through groove and the first through groove respectively, the operator only needs to pick up a flathead screwdriver and insert it into the flathead groove and the flathead inside the square groove and the third sliding groove through the second through groove and the first through groove. This facilitates the adjustment of the height of the limit pin and the adjustment of the distance between the limit pins without disassembly, making it more convenient to use.

[0032] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0033] Please see Figures 1-11The present invention provides an automotive seat spring bending and forming device, including a bending and forming device body 11, a processing shaft 12 is provided on the side wall of the bending and forming device body 11, a connecting rod 13 is provided on the side wall of the processing shaft 12, a bending motor 14 is fixedly installed inside the connecting rod 13, an outer ring 15 is fixedly installed on the output shaft of the bending motor 14, a plurality of bending pins 16 are fixedly installed on the upper end of the outer ring 15, and a first through groove 17, a second through groove 18 and a third through groove 19 are respectively opened on the circumferential surface of the outer ring 15;

[0034] An adjustable mechanism is fixedly installed at the upper end of the bending motor 14;

[0035] The adjustable mechanism includes an inner ring 21, which is rotatably mounted inside the outer ring 15. A first groove 22 is formed inside the inner ring 21. A dust collection groove 23 and a square groove 24 are respectively formed through the inner wall of the first groove 22. A second groove 25 is formed inside the inner ring 21, located above the first groove 22 and communicating with it. A third groove 26 is formed through the side wall of the second groove 25. The dust collection groove 23, the square groove 24, and the third groove 26 are parallel to the third through groove 19, the second through groove 18, and the first through groove 17, respectively. The adjustable mechanism also includes a threaded rod 27, a fixing block 28, a driven bevel gear 29, a synchronous belt 31, and a driving mechanism. The bevel gear 32, threaded block 34, first slot 35, fixed post 36, support box 37, fourth slide groove 38, second slot 39, double-acting screw 41, transmission block 42, limit pin 43, flathead screw 44, and third slot 45 are arranged parallel to the second through groove 18 and the first through groove 17, respectively. This allows workers to simply use a flathead screwdriver to insert it into the flathead slot 33 and the flathead screw 44 inside the square groove 24 and the third slide groove 26 through the second through groove 18 and the first through groove 17. This facilitates the adjustment of the height of the limit pin 43 and the spacing between the limit pins 43 without disassembly, making it convenient to use.

[0036] The threaded rod 27 is rotatably installed inside the square groove 24. The fixing block 28 is fixedly installed on the circumferential surface of the inner ring 21, and is located below the square groove 24. The driven bevel gear 29 is rotatably installed above the fixing block 28. The timing belt 31 is rotatably installed between the threaded rod 27 and the driven bevel gear 29, and is located in the square groove 24. The driving bevel gear 32 is rotatably installed on the circumferential surface of the inner ring 21 and meshes with the driven bevel gear 29. A slot 33 is formed on the rotating column of the driving bevel gear 32. The threaded block 34 is threadedly installed on the circumferential surface of the threaded rod 27 and slides with the first sliding groove 22. Each first slot 35 is formed through the inside of the threaded block 34. Two fixing posts 36 are fixedly installed at the upper end of the threaded block 34, and both fixing posts 36 are partially exposed in the second sliding groove 25. Inside, both fixed posts 36 are slidably installed with the inner ring 21. When the operator picks up a flathead screwdriver and inserts it into the slot 33 on the driving bevel gear 32, the head of the screwdriver generates a radial force that drives the driving bevel gear 32 to rotate on the inner ring 21 and mesh with the driven bevel gear 29. This causes the driven bevel gear 29 to rotate on the fixed block 28. At the same time, the timing belt 31 drives the threaded rod 27 to rotate and engages with the threaded block 34. This causes the threaded block 34 to drive the fixed posts 36 to move upward in the first slide groove 22, thereby pushing the support box 37 to move upward as a whole. As the support box 37 rises, the distance that the limit pin 43 is exposed above the outer ring 15 will increase. This allows the height of the limit pin 43 to be adjusted according to the size of the spring material being processed, thus improving its applicability.

[0037] The support box 37 is fixedly installed between the fixed posts 36. The support box 37 is slidably installed with the second slide groove 25. The fourth slide groove 38 is opened inside the support box 37. Each second slot 39 is opened through the lower part of the fourth slide groove 38. The bidirectional lead screw 41 is rotatably installed inside the fourth slide groove 38. Part of the bidirectional lead screw 41 is exposed outside the third slide groove 26. Both transmission blocks 42 are threaded on the circumferential surface of the bidirectional lead screw 41. Both transmission blocks 42 are slidably installed inside the fixed block 28. Both limit pins 43 are fixedly installed at the upper end of the transmission blocks 42. The flathead screwdriver 44 is fixedly installed on the side wall of the bidirectional lead screw 41. Each third slot 45 is opened through the top of the first slide groove 22 and the bottom of the second slide groove 25. When the operator picks up a flathead screwdriver and inserts it into the flathead screwdriver 44 through the first through groove 17 to rotate it, the flathead screwdriver 44 will generate a radial force to drive the entire bidirectional lead screw 41 to rotate in the fourth slide groove 38 inside the support box 37. This causes the bidirectional lead screw 41 to engage with the transmission block 42 via threaded transmission, which in turn causes the two transmission blocks 42 to drive the limiting pins 43 in the fourth slide groove 38 to move away from or towards each other, thereby adjusting the distance between the two limiting pins 43. This allows for the adaptation to spring materials of different sizes, further improving applicability. When the bending and forming device body 11 finishes processing a spring, the cutting blade of the bending and forming device body 11 will cut the part. However, after the cutting blade cuts the spring, some powder will fall into the second slide groove 25. By setting the first drain groove 35, the second drain groove 39, and the third drain groove 45, the operator can use an air gun to blow the powder in the inner ring 21 into the bottom of the first slide groove 22. The operator only needs to insert the vacuum cleaner head into the vacuum groove 23 and start it to clean the powder in the inner ring 21, preventing the powder in the inner ring 21 from accumulating and jamming the movement of the adjustable mechanism, thus improving the stability of the device.

[0038] Working principle:

[0039] The first step is to adjust the height of the limit pin 43 according to the diameter of the wire when bending the spring material.

[0040] When the height of the limiting pin 43 needs to be adjusted, the operator can first pick up a flathead screwdriver and insert it into the slot 33 on the drive bevel gear 32 through the second through slot 18 on the outer ring 15. Then, the operator can rotate the flathead screwdriver so that the head of the screwdriver generates a radial force to drive the drive bevel gear 32 to rotate on the inner ring 21 and mesh with the driven bevel gear 29, causing the driven bevel gear 29 to rotate on the fixed block 28. At this time, the synchronous belt 31 in the square slot 24 will drive the threaded rod 27 to rotate in the first slide groove 22. At this time, the threaded rod 27 will have threaded transmission with the threaded block 34, which will cause the threaded block 34 to drive the fixed column 36 to move upward in the first slide groove 22, thereby pushing the support box 37 to move upward as a whole. Due to the rise of the support box 37, the height of the limiting pin 43 exposed above the outer ring 15 will increase.

[0041] The second step is to adjust the spacing between the limit pins 43 according to the wire dimensions when bending the spring material.

[0042] When it is necessary to adjust the distance between the limit pins 43, the operator can first pick up the flathead screwdriver again and insert it into the flathead 44 through the first through slot 17 to rotate it. At this time, the flathead 44 will generate a radial force to drive the bidirectional lead screw 41 to rotate in the fourth slide groove 38 in the support box 37, so that the bidirectional lead screw 41 and the transmission block 42 respectively have threaded transmission, and then the two transmission blocks 42 slide in the fourth slide groove 38 in a direction that moves away from or towards each other. At the same time, the movement of the transmission block 42 will drive the limit pins 43 to move. When the limit pins 43 are adjusted to the appropriate position, the rotation of the flathead 44 can be stopped, and the bending forming device body 11 can be opened, so that the bending forming device body 11 extends the spring material through the processing shaft 12 and enters between the limit pins 43. At this time, the bending motor 14 will drive the outer ring 15 to rotate and use the bending pin 16 to bend the spring material.

[0043] The third step is to clean the powder inside the inner ring 21;

[0044] After the bending and forming device body 11 is used multiple times, some of the powder from each time the bending and forming device body 11 cuts the spring material will fall into the second slide 25. At this time, the powder will first fall onto the support box 37, and through the second trough 39, the powder can enter the first trough 35 and the third trough 45, and finally enter the dust collection trough 23. The operator can take the vacuum cleaner head and insert it into the first slide 22 through the third channel 19. Then the operator can turn on the air gun at the second slide 25, so that the powder enters the bottom of the first slide 22 through the second trough 39 and the third trough 45. Then the operator can turn on the vacuum cleaner to complete the cleaning of the powder.
