[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0032] This utility model provides a multi-station spring winding machine, such as Figure 1-6 As shown, the system includes: four coiling spring mechanisms, a material rack 1, a mold frame 2, a drive device 3, and a wire feeding device 4. The material rack 1 is used to hold the linear raw material. The wire feeding device 4 feeds the linear raw material onto the coiling spring mechanisms. The four coiling spring mechanisms are connected by a linkage mechanism, which is in turn connected to the drive device 3. The drive device 3 serves as the drive source to drive the linkage mechanism, enabling the four coiling spring mechanisms to operate synchronously. This allows for the simultaneous production of four coiled spring products, greatly improving production efficiency and meeting the needs of large-scale production.

[0033] In this embodiment, the material rack 1 includes a placement box 11, on which a plurality of material trays 12 for storing linear raw materials are provided. Each material tray 12 is equipped with a reducer 13 for feeding to achieve uniform feeding. The top of the material rack 1 is also provided with a plurality of first guide rollers 14, which are arranged in a row to guide the linear raw materials on the plurality of material trays 12, so as to avoid friction between the linear raw materials and the material rack 1, which would damage the coiled spring products and reduce their quality.

[0034] In this embodiment, four spring winding mechanisms are arranged correspondingly front and back on the mold frame 2. The spring winding mechanisms are used to wind the linear material to form a spring-shaped product. Specifically, the spring winding mechanism includes a first clamp 38, a second clamp 39, and a spring winding guide rod 310 clamped between the two clamps.

[0035] Specifically, during the spring winding process, the first clamp 38 and the second clamp 39 operate synchronously, driving the spring winding guide rod 310 to rotate, so that the linear material wound on the spring winding guide rod 310 forms a spring-shaped product structure. Furthermore, a rotating shaft 37 is connected to one end of each of the first clamp 38 and the second clamp 39, and the rotating shaft 37 is used to connect the drive device 3.

[0036] Furthermore, two "V"-shaped baffles 7 are provided at the bottom of the coiled spring guide rod 310 to support the coiled spring products and prevent the weight of the coiled spring products from bending the coiled spring guide rod 310 and affecting the coiling operation.

[0037] In this embodiment, the wire feeding device 4 is placed on one side of each spring guide rod 310 and moves horizontally along the spring guide rod 310. The linear raw material on the material tray 12 passes through the wire feeding device 4 and winds around the spring guide rod 310. The reducer 13 feeds the material according to the wire feeding speed of the wire feeding device 4. The spring winding mechanism continuously winds the spring. With the cooperation of the reducer 13, the material is continuously fed so that the spring winding speed and the wire feeding speed are consistent. The wire feeding device 4 moves horizontally according to the spring winding speed until it reaches the length set for the spring product. At this time, the reducer 13 also stops working, that is, the material feeding stops.

[0038] In this embodiment, the drive device 3 is located at the bottom of the frame 2, and its output end is connected to the linkage mechanism. The drive device 3 here is a rotary motor 31. The rotary motor 31 is connected to the linkage mechanism through a belt, and thus the linkage mechanism is connected to the rotating shaft 37 of the four coiled spring mechanisms to drive the multiple coiled spring mechanisms to operate synchronously, thereby realizing the simultaneous production of four coiled spring products and greatly improving production efficiency.

[0039] In this embodiment, the top surface of the frame 2 is provided with a linear guide rail 5 and an electric slide table 6 for assembling the wire feeding device 4. The linear guide rail 5 is designed parallel to the spring winding mechanism. Each linear guide rail 5 is provided with an electric slide table 6. The wire feeding device 4 is mounted on the electric slide table 6. The wire feeding device 4 moves on the linear guide rail 5 using the electric slide table 6, thereby enabling the wire feeding device 4 to feed the wire in an orderly manner along the spring winding guide rod 310 of the continuous spring winding, and thus cooperate with the spring winding mechanism to realize the spring winding processing of the linear raw material.

[0040] In this embodiment, the unloading device 8 is located at one end of the linear guide rail 5 and at one end of the spring winding mechanism. The cutting device 9 is located at the end of the spring winding mechanism. Each spring winding mechanism is equipped with an unloading device 8 and a cutting device 9.

[0041] Specifically, when the set length of the coiled spring product is completed, the wire feeding device 4, the reducer 13, and the drive device 3 stop simultaneously. The unloading device 8 pushes the coiled spring product on the coiled spring guide rod 310 to the position of the cutting device 9, and then the cutting device 9 cuts it, realizing automatic unloading and cutting of the product, further improving production efficiency and meeting the needs of large-scale production.

[0042] In this embodiment, the linkage mechanism includes a drive shaft 32, a first driving wheel 33, a first driven wheel 34, a large drive wheel 35, and a small drive wheel 36. The drive shaft 32 is rotatably mounted on the top of the frame 2 via bearings and is located on one side of the drive device 3. The output end of the drive device 3 is equipped with the first driving wheel 33, and the first driven wheel 34 is mounted on the drive shaft 32. A belt is sleeved between the first driving wheel 33 and the first driven wheel 34. Large drive wheels 35 are provided at both ends of the drive shaft 32, and small drive wheels 36 are provided on each rotating shaft 37. A belt is sleeved between the large drive wheels 35 and the small drive wheels 36.

[0043] Specifically, when driving the four coiling spring mechanisms to operate synchronously, the rotary motor 31 is started first. The rotary motor 31 drives the first driving wheel 33 to rotate, and drives the first driven wheel 34 to rotate synchronously through the belt, thereby causing the transmission shaft 32 to rotate. The rotating transmission shaft 32 drives the large transmission wheels 35 at both ends to rotate, and then drives the small transmission wheels 36 to rotate synchronously under the action of the belt, thereby causing the two rotating shafts 37 to rotate synchronously in the same direction, realizing the rotation of the coiling spring guide rod 310, so as to complete the coiling spring work of the linear material.

[0044] In this embodiment, the wire feeding device 4 includes a bracket 41, a second guide wheel 42, and a wire threading block 43. The second guide wheel 42 is rotatably mounted on the top of the bracket 41, and a bushing 44 for inserting the spring guide rod 310 is provided at the bottom of the bracket 41. A wire hole 45 for feeding the wire-shaped raw material is vertically opened on the wire threading block 43.

[0045] Specifically, the linear material on the feed tray 12 first passes through the first guide wheel 14, then through the second guide wheel 42, and finally passes through the wire hole 45. The spring guide rod 310 passes through the bushing 44, so that the linear material and the spring guide rod 310 are perpendicular to each other, thereby achieving the winding of the linear material while the spring guide rod 310 rotates, so that the linear material forms a spring-shaped structure.

[0046] In this embodiment, the unloading device 8 includes a servo motor 81, a second driving wheel 82, a second driven wheel 83, a timing belt 84, a connecting block 85, a slider 86, and a truss 87. The second driving wheel 82 and the second driven wheel 83 are located at both ends of the frame 2, and a timing belt 84 is sleeved between them. The servo motor 81 is connected to the bottom of the second driving wheel 82 to drive the second driving wheel 82 to rotate. A connecting block 85 is detachably mounted on the timing belt 84. The top of the connecting block 85 is connected to the truss 87. The bottom of the truss 87 is equipped with a slider 86, and the slider 86 is slidably connected to the linear guide rail 5 to support the truss 87.

[0047] Specifically, during unloading, the servo motor 81 drives the second drive wheel 82 to rotate, which in turn drives the second driven wheel 83 to rotate synchronously under the action of the synchronous belt 84. The running synchronous belt 84 drives the connecting block 85 to move. Under the action of the slider 86 sliding on the linear guide rail 5, the truss 87 moves horizontally, thereby pushing the wire feeding device 4. Then, the bushing 44 of the wire feeding device 4 pushes the product wound on the spring guide rod 310 to the cutting device 9.

[0048] It can be explained here that when the spring is pushed to the position of the second clamp 39, the second clamp 39 releases and stops clamping the spring guide rod 310, so that the spring product can pass smoothly through the second clamp 39 to the position of the cutting device 9 for cutting.

[0049] In this embodiment, the cutting device 9 includes a cylinder 91, a cutting blade 92, and a blade holder 93. The cylinder 91, the cutting blade, and the blade holder 93 are arranged sequentially from top to bottom. The cutting blade 92 is fixedly installed on the piston end of the cylinder 91.

[0050] Specifically, during the cutting process, the cylinder 91 drives the cutting blade 92 to move downwards, which, together with the blade holder 93, completes the cutting of the coiled spring product.

[0051] It can be noted that one end of the coiled spring guide rod 310 extends to one side of the cutter holder 93, enabling the cutting blade 92 to accurately cut the coiled spring product to the required dimensions.

[0052] The working principle of this utility model is as follows: the linear raw material on the material tray 12 passes through the first guide wheel 14, then through the second guide wheel 42, and finally passes through the wire hole 45 and is wound around the spring guide rod 310.

[0053] Then, the rotary motor 31 is started, which drives the first drive wheel 33 to rotate. The first driven wheel 34 is driven to rotate synchronously through the belt, thereby making the transmission shaft 32 rotate. The rotating transmission shaft 32 drives the large transmission wheels 35 at both ends to rotate, and under the action of the belt, it drives the small transmission wheel 36 to rotate synchronously. This causes the two rotating shafts 37 to rotate synchronously in the same direction, thereby realizing the rotation of the spring guide rod 310 to complete the spring winding work of the linear material.

[0054] It can be explained here that during the winding of the spring, the speed at which the reducer 13 drives the material tray 12 to release the wire, the moving speed of the wire release device 4, and the winding speed of the winding guide rod 310 remain stable and equal.

[0055] When the spring reaches the set length, the rotary motor 31, reducer 13, and wire feeding device 4 stop operating synchronously. At this time, the servo motor 81 drives the second drive wheel 82 to rotate, which in turn drives the second driven wheel 83 to rotate synchronously under the action of the synchronous belt 84. The running synchronous belt 84 drives the connecting block 85 to move. Under the action of the slider 86 sliding on the linear guide rail 5, the truss 87 moves horizontally, thereby pushing the wire feeding device 4. Then, the bushing 44 of the wire feeding device 4 pushes the product wound on the spring guide rod 310 to the knife holder 93 position. The cylinder 91 drives the cutting knife 92 to move downward, and together with the knife holder 93, the spring product is cut.

[0056] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
