Description

Technical Field

[0001] This utility model relates to the field of spring winding technology in spring production, and in particular to a spring winding device for spring processing. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. A part made of elastic material deforms under external force and returns to its original shape after the force is removed. It is also called a "spring". Springs are generally made of spring steel. There are many types of springs, mainly classified by shape as helical springs, spiral springs, leaf springs, and irregularly shaped springs. The most commonly used machinery in spring manufacturing is a spring winding device. Heated steel bars are spirally wound onto winding rollers to achieve the most basic spring production. However, existing spring winding devices often use winding rollers or rods of fixed sizes. If different types of springs are to be produced, these need to be replaced. The winding rollers are mostly fixed with bolts, which are prone to loosening during the rotation of the winding rollers, leading to instability. Furthermore, after winding one spring, it needs to be manually removed, which is time-consuming and laborious. To address these problems, we have introduced a spring winding device for spring processing. Utility Model Content

[0003] This utility model discloses a spring winding device for spring processing, which aims to solve the technical problems of existing spring winding devices, where the winding roller or winding rod is often of a fixed size and needs to be replaced if different models of springs are produced. The winding roller is mostly fixed by bolts, which are easy to loosen when rotating to wind the spring, resulting in unstable use. Furthermore, after winding one spring, the spring needs to be manually removed, which is time-consuming and laborious.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A spring winding device for spring processing includes a base plate, a side plate fixedly mounted on one side of the top of the base plate, a fixed seat connected to one side of the side plate via a drive mechanism, a spring winding roller fixed to the side of the fixed seat away from the side plate via a fixing assembly, and an auxiliary assembly connected to the top of the base plate near the spring winding roller via a moving assembly. The fixing assembly includes a slide groove, and slide grooves are symmetrically formed on both sides of the inner wall of the fixed seat. A bidirectional lead screw is rotatably connected inside one of the slide grooves, and two sliders are symmetrically slidably connected inside both of the slide grooves. The two ends of the bidirectional lead screw pass through the two sliders on the same side and are threadedly connected to the sliders. A motor is connected to the top of the fixed seat via a mounting bracket, and the output end of the motor is fixedly connected to the bidirectional lead screw. Adjacent sliders are connected by connecting plates, and insertion blocks are fixedly mounted on the side of the two connecting plates that are close to each other. Insertion slots are formed on the side of the spring winding roller that is close to the insertion blocks, and the insertion blocks extend into the corresponding insertion slots.

[0006] By setting a fixing component, one end of the winding roller is placed between two connecting plates. The motor output drives the bidirectional lead screw to rotate, which in turn drives the two connecting plates to move towards the winding roller via a slider. This allows the two insertion blocks to extend into their corresponding insertion slots, facilitating quick fixing of the winding roller and easy replacement of the winding roller according to the required spring size. This is simple and convenient, solving the problems of existing winding roller devices where the winding roller or winding rod is often of a fixed size and needs to be replaced if different models of springs are produced. The winding roller is mostly fixed with bolts, which are prone to loosening when rotating with the winding roller, resulting in unstable use.

[0007] In a preferred embodiment, the auxiliary component includes a mounting plate, a vertical plate fixedly mounted on the top of the mounting plate near the spring roller, a conveying mechanism disposed on the top of the mounting plate away from the spring roller, a fixing plate fixedly mounted on the vertical plate near the spring roller, a connecting groove formed inside the fixing plate near the spring roller, a connecting seat installed inside the connecting groove, a push ring fixedly mounted in the middle of the connecting seat, and the connecting seat fixed inside the connecting groove by a fixing screw and a nut, a fixing blade fixedly mounted on the top of the auxiliary component near the spring roller, and a movable blade connected to the side of the vertical plate near the fixing blade by an electric telescopic rod.

[0008] The conveying mechanism at the top of the auxiliary component facilitates the movement of the metal wire. The fixed blade, electric telescopic rod, and moving blade facilitate the cutting of the finished product after molding. The connecting seat, which is fixed by a screw and nut in the middle of the connecting groove inside the fixed plate, has a push ring inside that passes through the spring roller and slides on the outside of the spring roller. This allows the finished product to be pushed out in a direction away from the side plate after the spring is formed, eliminating the need for manual unloading and saving time and effort.

[0009] In a preferred embodiment, the moving component includes a moving groove. The bottom plate has symmetrically opened moving grooves on its top and near the auxiliary component. Moving blocks are symmetrically fixedly installed on the bottom of the mounting plate. Each moving block extends into the corresponding moving groove and is slidably connected to the moving groove. A lead screw is connected to one of the moving grooves through a second drive mechanism. The lead screw is rotatably connected to the moving groove and passes through one of the moving blocks and is threadedly connected to the moving block.

[0010] The movable component is set up so that the second drive mechanism is activated to drive the lead screw to rotate, which in turn drives the movable block to move, thereby moving the entire auxiliary component. This facilitates the feeding of wire by the auxiliary spring and the unloading of finished products.

[0011] In a preferred embodiment, a positioning block is fixedly installed on the side of the coiled spring roller near the fixed seat. A positioning groove is formed inside the fixed seat near the positioning block. Installation grooves are symmetrically formed inside the fixed seat on both sides of the positioning groove. A spring is fixedly installed inside each of the installation grooves. A locking block is fixedly installed on the side of the spring near the positioning groove. A locking groove is formed on the positioning block and near the locking block. The locking block extends into the locking groove.

[0012] By setting a positioning block that extends into the positioning groove, and by using a spring to push the locking block to extend into the locking groove, it is easy to initially position the coiled roller inside the fixed seat, which is simple, quick and convenient.

[0013] In a preferred embodiment, a fixing rod is fixedly installed inside another of the slides, the fixing rod passing through the corresponding slider and slidably connected to the slider.

[0014] A fixed rod is fixed inside another groove, and the slider is slidably connected to the fixed rod, which makes the displacement of the two connecting plates more stable.

[0015] In a preferred embodiment, a limiting rod is fixedly installed inside another of the movable slots, the limiting rod passing through the other movable block and slidably connected to the movable block.

[0016] The limiting rod fixed inside another moving slot facilitates a more stable movement of the mounting plate by sliding the moving block and the limiting rod together.

[0017] The spring winding device for spring processing provided by this utility model has the following advantages:

[0018] Firstly, by setting a fixing component, one end of the winding roller is placed between two connecting plates. The motor output drives the bidirectional lead screw to rotate, which in turn drives the two connecting plates to move towards the winding roller via a slider. This allows the two insertion blocks to extend into their corresponding insertion slots, facilitating quick fixing of the winding roller and easy replacement of the winding roller according to the required spring size. This is simple and convenient, solving the problem that existing winding rollers or winding rods are often of fixed size, requiring replacement if different spring models are produced. Furthermore, winding rollers are mostly fixed with bolts, which can easily loosen and cause instability when rotating with the winding roller.

[0019] Secondly, the conveying mechanism at the top of the auxiliary component facilitates the movement of the metal wire. The fixed blade, electric telescopic rod, and moving blade facilitate the cutting of the finished product after molding. The connecting seat, which is fixed by a screw and nut in the middle of the connecting groove inside the fixed plate, has a push ring inside that passes through the spring roller and slides on the outside of the spring roller. This facilitates the movement away from the side plate after the spring is formed, pushing out the finished product without the need for manual unloading, saving time and effort.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0026] The spring winding device disclosed in this utility model is mainly used in the scenario of spring winding.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A spring winding device for spring processing includes: a base plate 1; a side plate 2 is fixedly installed on one side of the top of the base plate 1; a fixed seat 8 is connected to one side of the side plate 2 via a first drive mechanism 3; a winding roller 5 is fixed to the side of the fixed seat 8 away from the side plate 2 via a fixing assembly 4; an auxiliary assembly 7 is connected to the top of the base plate 1 near the winding roller 5 via a moving assembly 6; the fixing assembly 4 includes a groove 41; grooves 41 are symmetrically opened on both sides of the inner wall of the fixed seat 8; a bidirectional lead screw 42 is rotatably connected inside one of the grooves 41; and the two grooves 41 are rotatably connected inside... Two sliders 43 are symmetrically slidably connected. The two ends of the bidirectional lead screw 42 pass through the two sliders 43 on the same side and are threaded to the sliders 43. A motor 45 is connected to one side of the top of the fixed base 8 through the mounting bracket 44. The output end of the motor 45 is fixedly connected to the bidirectional lead screw 42. Two adjacent sliders 43 are connected by a connecting plate 46. A plug-in block 47 is fixedly installed on the side of the two connecting plates 46 that are close to each other. A plug-in groove 48 is opened on the side of the spring roller 5 that is close to the plug-in block 47. The plug-in block 47 extends into the corresponding plug-in groove 48.

[0028] In this design, a positioning block 49 is fixedly installed on the side of the coiled roller 5 near the fixed base 8. A positioning groove 411 is opened inside the fixed base 8 near the positioning block 49. Installation grooves 412 are symmetrically opened inside the fixed base 8 on both sides of the positioning groove 411. A spring 413 is fixedly installed inside each of the installation grooves 412. A locking block 414 is fixedly installed on the side of the spring 413 near the positioning groove 411. A locking groove 410 is opened on the positioning block 49 near the locking block 414. The locking block 414 extends into the locking groove 410. By setting the positioning block 49 to extend into the positioning groove 411, and by the spring 413 pushing the locking block 414 to extend into the locking groove 410, it is easy to fix the coiled roller 5 in the fixed base 8 for initial positioning, which is simple, quick and convenient.

[0029] One of the slides 41 has a fixed rod 415 fixedly installed inside it. The fixed rod 415 passes through the corresponding slider 43 and is slidably connected to the slider 43. Through the fixed rod 415 fixed inside the other slide 41, and the slider 43 is slidably connected to the fixed rod 415, the displacement of the two connecting plates 46 is made more stable.

[0030] In this embodiment, by setting a fixing component 4, one end of the winding roller 5 is placed between two connecting plates 46. The output end of the motor 45 drives the bidirectional lead screw 42 to rotate, and then the slider 43 drives the two connecting plates 46 to move towards the winding roller 5, so that the two insertion blocks 47 extend into the corresponding insertion slots 48 respectively, which facilitates quick fixing of the winding roller 5 and makes it easy to replace the winding roller 5 according to the size of the spring 413 to be processed. It is simple and convenient, and solves the problem that in the existing winding devices, the winding roller or winding rod is often of a fixed size. If different models of springs are produced, they need to be replaced. The winding roller is mostly fixed by bolts, which are easy to loosen when rotating with the winding spring, resulting in unstable use.

[0031] In the above technical solution, considering the issue of removing the forming spring, the specific operation is as follows to solve this problem:

[0032] Reference Figure 1 and Figure 2 In a preferred embodiment, the auxiliary component 7 includes a mounting plate 71. A vertical plate 72 is fixedly mounted on the top of the mounting plate 71 near the side of the coiled spring roller 5. A conveying mechanism 73 is provided on the top of the mounting plate 71 away from the coiled spring roller 5. A fixing plate 74 is fixedly mounted on the side of the vertical plate 72 near the coiled spring roller 5. A connecting groove 77 is provided inside the fixing plate 74 near the coiled spring roller 5. A connecting seat 75 is installed inside the connecting groove 77. A push ring 76 is fixedly mounted in the middle of the connecting seat 75. The connecting seat 75 is fixed inside the connecting groove 77 by a fixing screw 78 and a nut 79. A fixing blade 710 is fixedly mounted on the top of the auxiliary component 7 near the side of the coiled spring roller 5. A moving blade 712 is connected to the side of the vertical plate 72 near the fixing blade 710 by an electric telescopic rod 711.

[0033] The movable component 6 includes a movable slot 61. The movable slot 61 is symmetrically provided on the top of the base plate 1 and near the auxiliary component 7. Movable blocks 62 are symmetrically fixedly installed on the bottom of the mounting plate 71. The movable blocks 62 extend into the corresponding movable slot 61 and are slidably connected to the movable slot 61. A lead screw 63 is connected to one of the movable slots 61 through a second drive mechanism 64. The lead screw 63 is rotatably connected to the movable slot 61 and passes through one of the movable blocks 62 and is threadedly connected to the movable block 62. By activating the movable component 6 and driving the second drive mechanism 64 to rotate the lead screw 63, the movable block 62 is moved, thereby moving the entire auxiliary component 7. This facilitates the feeding of wire by the auxiliary spring 413 and the unloading of finished products.

[0034] One of the moving slots 61 has a limiting rod 65 fixedly installed inside. The limiting rod 65 passes through the moving block 62 on the other side and is slidably connected to the moving block 62. The limiting rod 65 fixed inside the other moving slot 61 makes the movement of the mounting plate 71 more stable by sliding the moving block 62 and the limiting rod 65.

[0035] In this embodiment, the conveying mechanism 73 at the top of the auxiliary component 7 facilitates the movement of the metal wire. The fixed blade 710, electric telescopic rod 711, and moving blade 712 facilitate the cutting of the finished product after molding. The connecting seat 75, which is fixed in the middle of the connecting groove 77 inside the fixed plate 74 by the fixing screw 78 and nut 79, has a push ring 76 inside the connecting seat 75 that passes through the spring roller 5 and slides on the outside of the spring roller 5. This facilitates the movement away from the side plate 2 after the spring 413 is formed, pushing out the finished product without the need for manual unloading, saving time and effort.

[0036] Working principle: In use, by setting the fixing component 4, one end of the winding roller 5 is placed between the two connecting plates 46. The output end of the motor 45 drives the bidirectional lead screw 42 to rotate, and then the slider 43 drives the two connecting plates 46 to move towards the winding roller 5, so that the two insertion blocks 47 extend into the corresponding insertion slots 48, which facilitates quick fixing of the winding roller 5 and easy replacement of the winding roller 5 according to the size of the spring 413 to be processed. It is simple and convenient. It solves the problem that in the existing winding device, the winding roller or winding rod is often of a fixed size. If different models of springs are produced, they need to be replaced. The winding roller is mostly fixed by bolts, which are easy to loosen when rotating with the spring, resulting in unstable use. By setting the moving component 6 and the auxiliary component 7, it solves the technical problem that in the existing winding device, after one spring is wound, the spring needs to be removed manually, which is time-consuming and laborious.

[0037] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
