Description

Technical Field

[0001] The invention belongs to the technical field of spring bending equipment, in particular to a spring bending device for a trampoline. Background Art

[0002] In the field of mechanical manufacturing, springs are widely used in the fields of automobiles, aerospace, mechanical equipment, etc. For example, in automobile manufacturing, springs are used in important parts such as suspension systems, brake systems and engines. At the same time, springs also have important applications in industries such as electronic products, furniture, and medical equipment.

[0003] The traditional method for producing bent tube springs is to first use a spring machine to roll the steel wire into a straight tube spring, and then manually beat and bend it to obtain a bent tube spring. This method has low production efficiency, is time-consuming and labor-intensive, and the bending accuracy is difficult to control. Therefore, in recent years, a variety of innovative spring bending devices have emerged, such as the use of internal support bends and heating wire designs to speed up spring bending and avoid deformation; or the use of motors to drive rollers to rotate the steel bars around the rollers to form a spring-type steel bar structure.

[0004] The current spring bending device mainly focuses on how to quickly complete the spring bending process, while ignoring the subsequent processing of the spring after forming, such as spraying anti-rust oil and sorting and collection. The existing equipment usually allows the spring to fall freely to the ground or into a box after the spring is formed, which not only easily causes the springs to be entangled with each other, but is also not conducive to subsequent anti-rust treatment. In order to solve this technical problem, the present invention proposes a bending device specifically for trampoline spring production, which aims to improve the processing flow after the spring is formed. Summary of the invention

[0005] The purpose of the present invention is to provide a spring bending device for a trampoline to solve the problems raised in the above background technology.

[0006] The bending assembly includes a pressure wheel group, a rotating wheel group, a driving roller, a top wheel seat and a top wheel; a straight plate is fixedly installed in the spring processing box, and a pressure wheel group, a rotating wheel group and a driving roller are rotatably installed on the straight plate. The pressure wheel group and the rotating wheel group are arranged in parallel, and a top wheel is arranged at the outer circumference of the driving roller, and the top wheel is connected to the straight plate through the top wheel seat. When the equipment starts working, the steel wire enters the bending assembly through the shearing assembly. At this time, the driving motor drives the rotating wheel group and the driving roller to rotate, and the steel wire is driven to be bent into a spring by the cooperation of the moving wheel and the driving roller, and then falls into the oil arrangement and spraying assembly, and is sent to the collection assembly by the oil arrangement and spraying assembly for easy sorting and recycling.

When the steel wire passes through the bending component 5 and becomes a spring, it enters the range of motion of the moving rod 606 through the spring slide plate 601. At this time, the rotation of the shaft drives the gear 1 603 to rotate, and the gear 1 603 drives the meshing gear 614 to rotate, thereby driving the rotating rod 2 611 to rotate. The rotating rod 605 rotates to drive the long rod 607 and the rotating short rod to rotate, so that the long rod 607 drives the moving rod 606 to move back and forth, and the formed spring is sent to the oil injection area. When the long rod 607 rotates, the extrusion plate 613 is driven by the extrusion rod 608 to slide in the oil tank 612 to extrude the anti-rust oil, so that it is sprayed out from the small hole of the oil outlet to prevent rust on the spring. When the long rod 607 returns, the reset spring 609 is used to quickly reset the extrusion plate 613, and the anti-rust oil sprayed next time is absorbed through the oil suction pipe 12.

[0035] like Figure 5 As shown, a plurality of oil outlet pipes are installed at the output end of the oil tank 612, and a plurality of small holes are evenly opened on the plurality of oil outlet pipes. An oil suction pipe 12 is installed at the input end of the oil tank 612, and the oil suction pipe 12 is connected to the oil storage tank.

[0036] like Figure 6-Figure 8As shown, a spring channel is fixedly installed at the output end of the spring slide plate 601, and double-rod moving plates 708 are symmetrically installed on both sides of the spring channel. A rotating block 1 706 and a rotating block 2 707 are fixedly installed below the double-rod moving plate 708.

A box body 709 is arranged below the input end of the spring channel, and a rotating shaft 2 703 is inserted and installed on both sides of the box body 709. L-shaped driving rods 702 are fixedly installed at the ends of the two rotating shafts 2 703 outside the box body 709, and one end of the two L-shaped driving rods 702 parallel to the rotating shaft 2 703 slides and is inserted in the long hole 705. The ends of the two rotating shafts 2 703 in the box body 709 are fixedly installed with rotating gears 710. When gear 2 604 rotates, it drives driving gear 701 to rotate, and then transmits power to rotating shaft 2 703 through rotating rod 11. The two rotating shafts 703 rotate, and then drive the L-shaped driving rods 702 at both ends to rotate. The long hole 705 at the sliding end of the L-shaped driving rod 702 slides, drives the arc plate 704 to move up and down, and then drives the two double-rod moving plates 708 to move up and down, and transports the rust-proofed springs to the collection table in batches to avoid spring winding.

[0037] like Fig. 9 As shown, a rotating rod 11 is inserted into the box body 709, a driving gear 701 is installed at one end of the rotating rod 11 outside the box body 709, and a gear three 1101 is installed at one end of the rotating rod 11 inside the box body 709.

[0038] like Figure 1 As shown, the hollow spiral rod 408 and the circular hole are located on the same horizontal line.

[0039] The working principle of the present invention is as follows: when the device is running, the motor 411 starts, and the motor 411 drives the driving wheel 409 at the output end to rotate, and then drives the driven wheel 410 meshing with it to rotate. At this time, the hollow spiral rod 408 rotates, driving the moving cylinder 407 that is spirally matched with it to move. When the moving cylinder 407 moves, the L-shaped shearing knives 403 are driven to approach or move away from each other through multiple connecting rods 406. When multiple L-shaped shearing knives 403 approach each other, the steel wire is sheared from multiple directions.

When the long rod 607 rotates, the extrusion plate 613 is driven by the extrusion rod 608 to slide in the oil tank 612 to extrude the anti-rust oil, so that it is sprayed out from the small hole of the oil outlet to prevent rust on the spring. When the long rod 607 returns, the reset spring 609 is used to quickly reset the extrusion plate 613, and the anti-rust oil sprayed next time is absorbed through the oil suction pipe 12.

[0041] Finally, when gear 2 604 rotates, it drives the driving gear 701 to rotate, and then transmits power to the rotating shaft 2 703 through the rotating rod 11. The two rotating shafts 703 rotate, and then drive the L-shaped driving rods 02 at both ends to rotate. The tail of the L-shaped driving rod 702 slides in the long hole 705 on the arc plate 704, driving the arc plate 704 to move up and down, and then drives the two double-rod moving plates 708 to move up and down, and transports the rust-proofed springs to the collection table in batches to avoid spring winding.
