Description

Technical Field

[0001] This application relates to the field of spring manufacturing equipment technology, and more particularly to a spring coiling machine. Background Technology

[0002] A spring is a mechanical part that operates using elasticity. Parts made of elastic materials deform under external force and return to their original shape after the force is removed. As a widely used elastic element in the machinery industry, the processing precision and efficiency of springs directly affect the performance and production costs of mechanical equipment. Currently, the spring manufacturing industry is developing towards automation and high precision.

[0003] Existing traditional production methods employ manual or semi-automatic methods, requiring workers to manually operate the coiling mechanism to wind wire into springs. This necessitates constant worker involvement, especially during wire feeding and spring collection, which rely on manual assistance. This approach cannot meet the demands of large-volume, standardized, and high-quality production. Furthermore, it cannot quickly switch between equipment for producing springs of different sizes, resulting in decreased production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a spring coiling machine that overcomes these deficiencies. It aims to solve the problem that traditional production methods rely on manual or semi-automatic processes, requiring workers to manually operate the coiling mechanism to wind wire for spring production. This necessitates constant worker involvement, especially during wire feeding and spring collection, which cannot meet the demands of large-volume, standardized, and high-quality production. Furthermore, the machine cannot quickly switch between different specifications when producing springs of varying sizes, leading to decreased production efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: a spring coiling machine, comprising a frame, a wire feeding mechanism and two sets of cutting mechanisms arranged on one side of the frame, the two sets of cutting mechanisms being symmetrically arranged vertically, each cutting mechanism including a linkage drive device, a fixed frame slidably connected to the bottom of the linkage drive device, the fixed frame being fixedly connected to the frame, a cutting blade being provided at the bottom of the linkage drive device, two sets of winding mechanisms being provided on one side of each of the two sets of cutting mechanisms, the wire feeding mechanism including a conveyor frame, multiple sets of conveyor rollers arranged laterally intersecting each other on one side of the conveyor frame, two sets of wire pressing mechanisms being arranged between the wire feeding mechanism and the two sets of cutting mechanisms, the two sets of wire pressing mechanisms being symmetrically arranged, a wire fixing frame being provided between the two sets of cutting mechanisms and the two sets of winding mechanisms, and a collecting hopper being provided at the bottom of the two sets of cutting mechanisms.

[0006] By adopting the above technical solution and setting up a frame, the frame can effectively support the entire component during use. The wire feeding mechanism is responsible for feeding the external metal wire into the space between two sets of cutting mechanisms and two sets of winding mechanisms. Two sets of symmetrically arranged wire pressing mechanisms press the metal wire down to make it taut before the winding mechanisms. During the continuous feeding process, the wire is abutted by the two sets of winding mechanisms, and one end of the wire slides outside the two sets of winding mechanisms in turn, achieving the effect of being bent around the wire frame. The subsequent continuous feeding of the wire causes the wire to bend forward and form a spring. The cutting mechanism cuts the wire in cooperation with the outer wall of the wire frame where the spring is formed. The formed spring falls into the collection hopper below for collection. In this way, the production and collection of springs can be completed automatically without the need for manual operation by the staff, realizing fully automated production, improving production efficiency and reducing production costs.

[0007] As a preferred technical solution of this application, a movable frame is provided on one side of the frame, a wire feeding mechanism is slidably connected inside the movable frame, and a wire organizing mechanism is provided on the side of the movable frame away from the frame.

[0008] By adopting the above technical solution and setting up a movable frame, the distance between the wire feeding mechanism and the two sets of wire pressing mechanisms can be adjusted during use. When conveying wires of different lengths and diameters, the wire feeding mechanism and the wire pressing mechanism can be flexibly adjusted to smoothly complete the wire conveying. When dealing with thicker diameter wires, the distance between the wire feeding mechanism and the wire pressing mechanism can be adjusted to avoid stress concentration, which could cause bending during wire conveying, thus improving production stability.

[0009] As a preferred technical solution of this application, a wire feeding mechanism is provided on one side of the frame. The wire feeding mechanism includes a base, a wire feeding reel is rotatably connected above the base, and four sets of casters are provided at the bottom of the base.

[0010] By adopting the above technical solution and setting up a wire feeding mechanism, the wire can be installed inside the wire feeding reel during use. When the wire feeding mechanism conveys the wire, it will automatically drive the wire feeding reel to rotate, thus completing the wire feeding operation. The base set at the bottom makes it more convenient to transfer and move the wire feeding mechanism, making it more flexible in use and improving the practicality of the device.

[0011] As a preferred technical solution of this application, the pressing mechanism includes a pressing roller, a sliding block is rotatably connected to one side of the pressing roller, a sliding groove is provided on the side of the frame corresponding to the pressing mechanism, and springs are provided on the sides of the two sets of sliding blocks that are far apart from each other.

[0012] By adopting the above technical solution and setting up a wire pressing mechanism, during use, the sliding block will continuously drive the two sets of sliding blocks to move to the same side. When the wire passes between the two sets of sliding blocks, it will be subjected to pressure from both the top and bottom sides. The cable is pressed between the two sets of wire pressing mechanisms, effectively preventing the wire from shifting during production.

[0013] As a preferred technical solution of this application, the two sets of winding mechanisms include mounting blocks, and a winding rod is fixedly mounted on one end of each set of mounting blocks facing the cutting mechanism. Multiple sets of connecting bolts are provided on the outside of the mounting blocks, and the multiple sets of connecting bolts are threaded through the mounting blocks and the frame.

[0014] By adopting the above technical solution and setting up a winding mechanism, the winding rod can fix the position of the winding mechanism during use, and different winding mechanisms can be replaced according to the diameter of the springs to be produced, thereby improving the practicality of the device.

[0015] As a preferred technical solution of this application, the cable management mechanism includes a cable management frame, and two sets of clamps are slidably connected inside the cable management frame. Each set of clamps has a cable management groove on one side opposite to the other, and each set of clamps has an adjusting screw rotatably connected to the side wall of the cable management frame.

[0016] By adopting the above technical solution and setting up a cable management frame, the cable will first be preliminarily straightened by two sets of clamps before entering the cable feeding mechanism for conveying, thereby improving the flatness of the cable when it enters the cable feeding mechanism and enhancing the stability during conveying.

[0017] As a preferred technical solution of this application, stabilizing grooves are provided on both sides of the inner side of the sliding groove, and stabilizing blocks that are slidably connected to the inner side of the stabilizing groove are fixedly connected to both sides of the two sets of sliding blocks.

[0018] By adopting the above technical solution and setting a stabilizing groove, the stability of the two sets of pressing mechanisms when moving inside the sliding groove can be improved during use, thereby enhancing the pressing effect.

[0019] As a preferred technical solution of this application, two sets of conveying shafts are provided between the wire feeding mechanism and the two sets of wire pressing mechanisms, and a fixed shaft is provided between the two sets of wire pressing mechanisms and the two sets of cutting mechanisms, the fixed shaft being located on one side of the wire fixing frame.

[0020] By adopting the above technical solution and setting a conveyor shaft, the wire can be supported when it is conveyed between the pressing mechanism and the feeding mechanism, thus avoiding local displacement and improving the practicality of the device.

[0021] The beneficial effects of this application are: 1. By setting up a frame, the machine can effectively support the entire component during use. The wire feeding mechanism is responsible for feeding the external metal wire into the space between two sets of cutting mechanisms and two sets of winding mechanisms. Two sets of symmetrically arranged wire pressing mechanisms press the metal wire down to make it taut before the winding mechanisms. During the continuous feeding process, the wire is pressed against the two sets of winding mechanisms, and one end of the wire slides outside the two sets of winding mechanisms in turn, achieving the effect of being bent around the wire frame. The continued feeding of the wire causes the wire to bend forward and form a spring. The cutting mechanism cuts the wire in cooperation with the outer wall of the wire frame where the spring is formed. The formed spring falls into the collection hopper below for collection. In this way, the spring production and collection can be completed automatically without manual operation by the operator, realizing fully automated production, improving production efficiency and reducing production costs.

[0022] 2. By setting up a movable frame, during use, the distance between the wire feeding mechanism and the two sets of wire pressing mechanisms can be adjusted to smoothly transport wires of different lengths and diameters. When dealing with thicker wires, the distance between the wire feeding mechanism and the wire pressing mechanism can be adjusted to avoid stress concentration, which could cause bending during wire transport, thus improving production stability.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] Reference Figure 1-6 A spring coiling machine includes a frame 1. A wire feeding mechanism 2 and two sets of cutting mechanisms 4 are arranged symmetrically vertically on one side of the frame 1. Each cutting mechanism 4 includes a linkage drive device 401. A fixed frame 402 is slidably connected to the bottom of the linkage drive device 401 and is fixedly connected to the frame 1. A cutting blade 403 is provided at the bottom of the linkage drive device 401. Two sets of winding mechanisms 5 are provided on one side of each of the two sets of cutting mechanisms 4. The wire feeding mechanism 2 includes a conveyor frame 201. One side of the conveyor frame 201... The frame 1 has multiple sets of transversely intersecting conveyor rollers 202 on one side. Two sets of wire pressing mechanisms 3 are arranged between the wire feeding mechanism 2 and the two sets of cutting mechanisms 4. The two sets of wire pressing mechanisms 3 are arranged symmetrically. A wire fixing frame 104 is arranged between the two sets of cutting mechanisms 4 and the two sets of winding mechanisms 5. A collection hopper 6 is arranged at the bottom of the two sets of cutting mechanisms 4. A wire feeding mechanism 7 is arranged on one side of the frame 1. The wire feeding mechanism 7 includes a base 701. A wire feeding reel 702 is rotatably connected above the base 701. Four sets of casters 703 are arranged at the bottom of the base 701.

[0027] By setting up the frame 1, the overall components can be effectively supported during use. The wire feeding mechanism 2 is responsible for feeding the external metal wire between the two sets of cutting mechanisms 4 and the two sets of winding mechanisms 5. The two sets of symmetrically arranged wire pressing mechanisms 3 press the metal wire before the winding mechanism to make it taut. During the continuous feeding process, the wire is abutted by the two sets of winding mechanisms 5, and one end of the wire slides outside the two sets of winding mechanisms 5 in turn, achieving the effect of being bent around the wire fixing frame 104. The subsequent continuous feeding of the wire causes the wire to bend forward continuously, forming a spring. The cutting mechanism 4 cuts the wire when it cooperates with the outer wall of the wire fixing frame 104 to form the spring. The formed springs will fall into the collection hopper 6 below for collection. This allows for fully automated spring production and collection, eliminating the need for manual operation and improving production efficiency while reducing costs. The wire feeding mechanism 7 allows the wire to be installed inside the wire feeding reel 702. The wire feeding mechanism 2 automatically rotates the wire feeding reel 702 during wire feeding. The base 701 at the bottom facilitates the transfer and movement of the wire feeding mechanism 7, enhancing the device's practicality.

[0028] Reference Figure 1-6A movable frame 105 is provided on one side of the frame 1. A wire feeding mechanism 2 is slidably connected inside the movable frame 105. A wire organizing mechanism 8 is provided on the side of the movable frame 105 away from the frame 1. The pressing mechanism 3 includes a pressing roller 301, with a sliding block 302 rotatably connected to one side of the pressing roller 301. A sliding groove 101 is provided on the side of the frame 1 corresponding to the pressing mechanism 3. Springs 303 are provided on the sides of the two sets of sliding blocks 302 that are far apart from each other. The wire organizing mechanism 8 includes a wire organizing frame 801, with two sets of clamping plates 802 slidably connected inside the wire organizing frame 801. Wire organizing grooves are provided on the opposite sides of the two sets of clamping plates 802. Adjusting screws 803, threadedly connected to the side walls of the wire organizing frame 801, are rotatably connected to one side of each set of clamping plates 802. By setting a movable frame 105, during use, the distance between the wire feeding mechanism 2 and the two pressing mechanisms 3 can be adjusted to smoothly feed wires of different lengths and diameters. When feeding thicker wires, the distance between the feeding mechanism 2 and the pressing mechanism 3 can be adjusted to avoid stress concentration, which could cause bending during wire feeding and improve production stability. By setting up the pressing mechanism 3, during use, the sliding block 302 continuously drives two sets of sliding blocks 302 to move to the same side. When the wire passes between the two sets of sliding blocks 302, it is subjected to pressure from both the top and bottom sides, and the cable is pressed between the two sets of pressing mechanisms 3, effectively preventing wire deviation during production. By setting up the wire guide frame 801, during use, the wire is first initially straightened by two sets of clamps 802 before entering the feeding mechanism 2 for feeding, improving the flatness of the wire when entering the feeding mechanism 2 and enhancing the stability of the feeding process.

[0029] Reference Figure 1-6The two sets of winding mechanisms 5 include mounting blocks 501. Each mounting block 501 has a winding rod 502 fixedly mounted on one end facing the cutting mechanism 4. Multiple sets of connecting bolts 503 are provided on the outside of the mounting blocks 501, and these bolts 503 thread through the mounting blocks 501 to connect with the frame 1. By setting up the winding mechanisms 5, the winding rods 502 can fix the position of the winding mechanisms 5 during use. Furthermore, different winding mechanisms 5 can be replaced according to the diameter of the springs to be produced, improving the practicality of the device. Stable grooves 102 are provided on both sides of the sliding groove 101. Both sides of the two sets of sliding blocks 302... A stabilizing block 304 is fixedly connected and slidably connected inside the stabilizing groove 102. By setting the stabilizing groove 102, the stability of the two sets of wire pressing mechanisms 3 when moving inside the sliding groove 101 can be improved during use, thus improving the wire pressing effect. Two sets of conveying shafts 9 are set between the wire feeding mechanism 2 and the two sets of wire pressing mechanisms 3, and a fixed shaft 103 is set between the two sets of wire pressing mechanisms 3 and the two sets of cutting mechanisms 4. The fixed shaft 103 is located on one side of the wire fixing frame 104. By setting the conveying shaft 9, the wire can be supported when it is conveyed between the wire pressing mechanism 3 and the wire feeding mechanism 2 during use, avoiding local displacement and improving the practicality of the device.

[0030] Working Principle: The frame 1 provides effective support for the entire component during use. The wire feeding mechanism 2 feeds the external metal wire between two sets of cutting mechanisms 4 and two sets of winding mechanisms 5. Two symmetrically arranged wire pressing mechanisms 3 press the metal wire taut before the winding mechanisms. During continuous feeding, the wire is pressed against the two winding mechanisms 5, and one end of the wire slides sequentially outside one end of each winding mechanism 5, achieving a bending effect around the wire support frame 104. Continuous feeding of the wire causes it to bend and advance, forming a spring. The cutting mechanism 4 cuts the wire in conjunction with the outer wall of the wire support frame 104 where the spring is formed. The formed spring then falls off. The springs are collected inside the collection hopper 6 below, thus completing the spring production and collection process automatically. No manual operation is required, achieving fully automated production, improving production efficiency, and reducing production costs. By setting up the moving frame 105, the distance between the wire feeding mechanism 2 and the two sets of wire pressing mechanisms 3 can be adjusted during use. When conveying wires of different lengths and diameters, the wire feeding mechanism 2 and the wire pressing mechanism 3 can be flexibly adjusted to smoothly complete the wire conveying. When dealing with thicker wires, the distance between the wire feeding mechanism 2 and the wire pressing mechanism 3 can be adjusted to avoid stress concentration, which could cause bending during wire conveying, thus improving production stability. The wire feeding mechanism 7 allows the wire to be installed inside the wire feeding reel 702 during use. The wire feeding mechanism 2 automatically rotates the wire feeding reel 702 when conveying the wire, completing the wire feeding operation. The base 701 at the bottom makes it easier to transfer and move the wire feeding mechanism 7, making it more flexible in use and improving the practicality of the device. The wire pressing mechanism 3 allows the sliding block 302 to continuously drive two sets of sliding blocks 302 to move to the same side during use. When the wire passes between the two sets of sliding blocks 302, it is subjected to pressure from the upper and lower sides. The wire is pressed between the two sets of wire pressing mechanisms 3, effectively preventing the wire from shifting during production. Meanwhile, by setting up the winding mechanism 5, the winding rod 502 can fix the position of the winding mechanism 5 during use, and different winding mechanisms 5 can be replaced according to the diameter of the spring to be produced, thereby improving the practicality of the device. In addition, by setting up the cable management frame 801, the cable will first be preliminarily straightened by two sets of clamps 802 before entering the cable feeding mechanism 2 for conveying, which improves the flatness of the cable when entering the cable feeding mechanism 2 and improves the stability during conveying; by setting up the stabilizing groove 102, the stability of the two sets of pressing mechanisms 3 when moving inside the sliding groove 101 can be improved during use, thus improving the pressing effect; by setting up the conveying shaft 9, the cable can be supported when it is conveyed between the pressing mechanism 3 and the cable feeding mechanism 2, avoiding local displacement and improving the practicality of the device.
