Description

Technical Field

[0001] This utility model relates to the field of wire winding equipment technology, specifically a wire winding equipment for spring production. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. It can deform under the action of external force and return to its original shape after the external force is removed. There are many types of springs. According to their shape, they mainly include helical springs, spiral springs, leaf springs, and irregularly shaped springs. Commonly used spring materials are divided into two categories: metallic materials and non-metallic materials. Commonly used metallic materials include: carbon steel for springs, stainless steel for springs, copper alloys and nickel alloys for springs, and other special alloys for springs. Springs are needed in the product processing and assembly process, so the demand for springs is increasing year by year.

[0003] Existing wire winding equipment for spring production has some drawbacks. First, during the wire winding process, when the metal wire is wound into a spring, the winding shaft rotates and falls off, requiring the removal of the spring. Afterward, the winding shaft needs to be reinstalled, which is labor-intensive and not easy to use. Second, the simple structure does not provide good positioning for the metal wire and spring, which can easily affect product quality. Utility Model Content

[0004] The purpose of this utility model is to provide a winding device for spring production, so as to solve the problems of being difficult to use and having poor positioning effect mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a winding device for spring production, comprising a rear support and a frame. The rear support is fixed to the rear end of the frame. A first wheel and a second wheel are rotatably connected to the upper end of the rear support, and the first and second wheel are meshed with each other. A motor is fixed to the upper end of the rear support, and the output end of the motor is fixedly connected to the driving end of the first wheel. A threaded post is threaded into the second wheel, and a partition is fixed to the front end of the threaded post. A wire-burning shaft is fixed to the front end of the partition. A stop block is fixed at the upper end of the wire-burning shaft, and a front bracket is fixed at the front end of the frame. The middle of the front bracket is rotatably connected to the wire-burning shaft. Driven by the motor, the first wheel rotates, which drives the second wheel to rotate, thereby driving the threaded column to move in the second wheel. The wire-burning shaft moves together, so that the metal wire is pulled backward while rotating, forming a spring shape. When the wire-burning shaft moves to the middle of the front bracket, the spring can be removed. When the first wheel and the second wheel rotate in opposite directions, the threaded column can move forward, thereby causing the wire-burning shaft to move to the middle of the front bracket.

[0006] As a further technical solution of this utility model, a fixing plate is fixed at the upper end of the partition, and a hydraulic cylinder is fixed at the upper end of the fixing plate. The hydraulic cylinder extends and drives the fixing plate to move down, which in turn drives the mounting block and connecting sleeve to move down, and the positioning block moves down together, thereby pressing and positioning the metal wire.

[0007] As a further technical solution of this utility model, the lower end of the hydraulic cylinder is fixed with a mounting block, and a connecting sleeve is provided on the outside of the mounting block.

[0008] As a further technical solution of this utility model, a locking block is fixed at the lower end inside the connecting sleeve, and the locking block is engaged with the mounting block. The mounting block limits the locking block through the corresponding slot, which helps to securely engage the connecting sleeve.

[0009] As a further technical solution of this utility model, a positioning block is fixed at the lower end of the connecting sleeve, and clamping blocks are fixed at the front and rear ends of the positioning block. A metal wire is provided in the middle of the clamping block. The clamping block can prevent the metal wire from shifting during the pressing process and ensure the stability of the metal wire on the positioning block.

[0010] As a further technical solution of this utility model, the connecting sleeve has bolts threaded on both sides, and one end of the bolt is threaded with the mounting block. Bolts can be screwed into both sides of the connecting sleeve respectively, so that the bolts are screwed into the mounting block to install the connecting sleeve, and then install the positioning block.

[0011] As a further technical solution of this utility model, a second hydraulic cylinder is fixed to the upper and lower parts of one end of the frame, and a pressure plate is fixed to one end of the second hydraulic cylinder. The second hydraulic cylinder extends and retracts, driving the pressure plate to rise and fall, thereby driving the guide roller to rise and fall.

[0012] As a further technical solution of this utility model, a guide roller is provided on the pressure plate, and a relief groove is provided in the middle of the guide roller. The guide roller limits the metal wire through the relief groove, which is conducive to the stable movement of the metal wire.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Driven by the motor, the first wheel rotates, which in turn drives the second wheel to rotate, thereby moving the threaded column in the second wheel. The wire-burning shaft moves together, causing the metal wire to rotate while being pulled backward to form a spring shape. When the wire-burning shaft moves to the middle of the front support, the spring can be removed. When the first and second wheels rotate in opposite directions, the threaded column can move forward, thereby moving the wire-burning shaft to the middle of the front support. It is easy to use.

[0015] The extension and retraction of the second hydraulic cylinder drives the pressure plate to rise and fall, which in turn drives the guide roller to rise and fall. The guide roller limits the metal wire through the relief groove, which helps the metal wire to move stably. Then, the first hydraulic cylinder extends, driving the fixed plate to move down, driving the mounting block and connecting sleeve to move down, and the positioning block to move down together. The positioning block presses and positions the metal wire. The clamping block can prevent the metal wire from shifting during the pressing process, ensuring the stability of the metal wire on the positioning block and achieving a good positioning effect.

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.

[0023] Please see Figure 1-5An embodiment of this utility model provides a winding device for spring production, including a rear support 20 and a frame 1. The rear support 20 is fixed to the rear end of the frame 1. A first wheel 22 and a second wheel 23 are rotatably connected to the upper end of the rear support 20, and the first wheel 22 and the second wheel 23 mesh with each other. A motor 21 is fixed to the upper end of the rear support 20, and the output end of the motor 21 is fixedly connected to the driving end of the first wheel 22. A threaded post 17 is threaded in the second wheel 23, and a partition 4 is fixed to the front end of the threaded post 17. A wire-burning shaft 3 is fixed to the front end of the partition 4, and a stop block 16 is fixed to the upper end of the wire-burning shaft 3. A front support 2 is fixed to the front end of the frame 1, and the middle of the front support 2 is rotatably connected to the wire-burning shaft 3.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, under the drive of motor 21, wheel 1 22 rotates, driving wheel 2 23 to rotate, which in turn drives threaded column 17 to move in wheel 2 23. The wire-burning shaft 3 moves together, so that the metal wire 9 is pulled backward while rotating, forming a spring shape. When the wire-burning shaft 3 moves to the middle of the front support 2, the spring can be removed. When wheel 1 22 and wheel 2 23 rotate in opposite directions, the threaded column 17 can move forward, which in turn causes the wire-burning shaft 3 to move to the middle of the front support 2.

[0025] A fixing plate 10 is fixed to the upper end of the partition 4, and a hydraulic cylinder 5 is fixed to the upper end of the fixing plate 10.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, the hydraulic cylinder 5 extends, causing the fixing plate 10 to move downward, which in turn causes the mounting block 11 and connecting sleeve 12 to move downward, and the positioning block 14 to move downward as well, thereby pressing and positioning the metal wire 9.

[0027] The lower end of the hydraulic cylinder 5 is fixed with a mounting block 11, and a connecting sleeve 12 is provided on the outside of the mounting block 11. The lower end of the connecting sleeve 12 is fixed with a locking block 18, and the locking block 18 is engaged with the mounting block 11.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, the mounting block 11 limits the position of the card block 18 through the corresponding card slot, which helps the connecting sleeve 12 to be securely engaged.

[0029] A positioning block 14 is fixed at the lower end of the connecting sleeve 12. Clamping blocks 15 are fixed at the front and rear ends of the positioning block 14, and a metal wire 9 is provided in the middle of the clamping block 15.

[0030] Specifically, such as Figure 1 and Figure 3 As shown, the clamping block 15 can prevent the metal wire 9 from shifting during the pressing process and ensure the stability of the metal wire 9 on the positioning block 14.

[0031] Bolts 13 are threaded on both sides of the connecting sleeve 12, and one end of the bolt 13 is threaded into the mounting block 11.

[0032] Specifically, such as Figure 1 and Figure 3 As shown, bolts 13 can be screwed into both sides of the connecting sleeve 12 respectively, so that the bolts 13 are screwed into the mounting block 11 to install the connecting sleeve 12, and then install the positioning block 14.

[0033] Hydraulic cylinder 2 8 is fixed at the upper and lower parts of one end of frame 1, and pressure plate 7 is fixed at one end of hydraulic cylinder 2 8.

[0034] Specifically, such as Figure 1 and Figure 3 As shown, hydraulic cylinder 28 extends and retracts, driving the pressure plate 7 to rise and fall, which in turn drives the guide roller 6 to rise and fall.

[0035] The pressure plate 7 is provided with a guide roller 6, and the guide roller 6 is provided with a relief groove 19 in the middle.

[0036] Specifically, such as Figure 1 and Figure 5 As shown, the guide roller 6 limits the movement of the metal wire 9 through the relief groove 19, which facilitates the stable movement of the metal wire 9.

[0037] Working principle: During use, hydraulic cylinder 28 extends and retracts, driving pressure plate 7 to rise and fall, which in turn drives guide roller 6 to rise and fall. Guide roller 6 limits the movement of metal wire 9 through relief groove 19, facilitating the stable movement of metal wire 9. Then, hydraulic cylinder 15 extends, driving fixed plate 10 to move downward, driving mounting block 11 and connecting sleeve 12 to move downward, and positioning block 14 to move downward together. Positioning block 14 presses and positions metal wire 9. Clamping block 15 prevents metal wire 9 from shifting during pressing, ensuring the stability of metal wire 9 on positioning block 14. Afterward, driven by motor 21, wheel 1 22 rotates, driving wheel 2 23 to rotate, which in turn drives threaded column 17 to rotate on wheel 2 23. The wire-burning shaft 3 moves along with the metal wire 9, causing it to rotate and be pulled backward, forming a spring shape. The wire-burning shaft 3 moves to the middle of the front support 2, where it can be removed. When the first wheel 22 and the second wheel 23 rotate in opposite directions, the threaded column 17 moves forward, thereby moving the wire-burning shaft 3 to the middle of the front support 2. In addition, the mounting block 11 limits the locking block 18 through the corresponding slot, which facilitates the secure locking of the connecting sleeve 12. Bolts 13 can be screwed into both sides of the connecting sleeve 12, so that the bolts 13 are screwed into the mounting block 11 to install the connecting sleeve 12, and then install the positioning block 14. This device is easy to use and has a good positioning effect.
