Description

Technical Field

[0001] This invention belongs to the field of spring manufacturing technology, and in particular relates to a spring winding device for spring processing. Background Technology

[0002] A spring is a mechanical part that uses its own deformation to generate force or store energy. It is used for buffering, absorbing vibration and controlling mechanical motion, or as a power source for instruments and clocks. It can also be used as a force measuring element. Commonly used springs in machinery can be classified according to the nature of the force they are subjected to, such as tension springs, compression springs, torsion springs and bending springs. According to their shape, they can be classified as helical springs, planar spiral springs, torsion bar springs, leaf springs, disc springs and ring springs. The production of springs requires winding steel wire into springs.

[0003] Currently, existing spring winding equipment still has the following problems during use: Because springs have different outer diameters, most existing winding equipment is only suitable for winding springs of one outer diameter specification. It cannot adapt to changes in the diameter of the spring steel wire raw material, lacking flexibility. Furthermore, larger diameter spring steel wire raw materials are more rigid, making it difficult for existing winding equipment to ensure tight winding of the spring coils, easily reducing processing accuracy. This results in a higher defect rate and unstable quality of the finished springs, thus affecting the manufacturer's production efficiency. Therefore, these shortcomings fail to meet the production needs of manufacturers, necessitating further improvement.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide spring winding equipment for spring processing, in order to achieve a more practical purpose. Summary of the Invention

The control unit is provided with a switch for controlling the winding device. The fixed seat is installed on the right side of the control unit, and the winding base is disposed on the rear side of the fixed seat.

A sliding rheostat is fixedly installed on the fixed bracket. A sensing plate is slidably installed on the sliding rheostat, and the sensing plate is electrically connected to the sliding rheostat. A connecting piece is provided between the sensing plate and the adjusting sleeve.

[0008] By adopting the above structure, when the diameter of the steel wire material is large, the kinetic energy output of the heating rod increases synchronously, and when the diameter of the steel wire material is small, the kinetic energy output of the heating rod decreases synchronously.

[0032] Beneficial effects

[0033] Compared with the prior art, the present invention provides a spring winding device for spring processing, which has the following beneficial effects:

[0034] 1. This spring winding equipment for spring processing, when the diameter of the steel wire raw material is large, when it passes between the upper and lower feed rollers, the reaction force of the fixed spring causes the upper feed roller to squeeze the steel wire raw material. By making the diameters on the left and right sides of the upper and lower feed rollers larger than the middle diameter, it is beneficial to limit the feeding of the steel wire raw material, locking it in the middle and keeping it in the center position. At the same time, it can avoid the possibility of the steel wire raw material shifting during the feeding process. It also solves the problem that traditional winding equipment cannot adapt to changes in the diameter of the spring steel wire raw material and lacks flexibility. Moreover, this setting can adjust the feeding according to steel wire raw materials of different diameters, further improving its performance.

[0035] 2. This spring winding equipment for spring processing, when the diameter of the steel wire raw material is large, causes the kinetic energy output of the heating rod to increase simultaneously, improving the heat treatment effect on the steel wire raw material. When the diameter of the steel wire raw material is small, the kinetic energy output of the heating rod to decrease simultaneously, reducing the heat output of the heating rod. On the one hand, it can ensure the heat treatment effect on the steel wire raw material, and on the other hand, it can effectively reduce the consumption of electrical energy, thereby avoiding the waste of electrical energy. Moreover, this setting allows it to automatically adjust based on the change of the diameter of the spring steel wire raw material, further improving the applicability of the device, and solving the problem that traditional winding equipment cannot automatically adjust according to the change of the diameter of the spring steel wire raw material.

[0036] 3. The spring winding equipment for spring processing, when the device drives the steel wire material to wind the spring through the winding rod, at the same time the heating rod generates heat through the control of the control unit and transfers the heat along the winding rod to the steel wire material. By heat treating the steel wire material, the rigidity of the steel wire material can be reduced, while the winding effect of the steel wire material can be improved. Furthermore, the spring after heat treatment and winding can further improve its mechanical properties.

[0037] 4. The spring winding equipment for spring processing generates kinetic energy through an electric telescopic device and uses a telescopic rod to push the mounting part to move. During the movement of the mounting part, the adjusting bracket moves synchronously, causing the adjusting bracket to slide on the winding rod and realize the effective adjustment of the spring length, which is beneficial for adjusting the spring according to different needs.

[0038] 5. The spring winding equipment for spring processing, the device starts the winding motor and drive mechanism, and uses the output end of the winding motor to drive the winding rod to rotate. As the winding rod drives the steel wire material to wind the spring, the adjusting frame also moves synchronously with the winding operation. This setting can improve the winding effect of the spring and avoid the possibility of the steel wire material getting stuck or repeatedly accumulating. Attached Figure Description

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other. For the convenience of description, the words "upper", "lower", "left", and "right" appearing below only indicate that they are consistent with the upper, lower, left, and right directions of the accompanying drawings themselves, and do not limit the structure. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] Please see Figures 1 to 11 A spring winding device for spring processing includes a frame 1. A control unit 2, a fixed seat 3 and a winding base 4 are fixedly arranged on the upper surface of the frame 1. The control unit 2 is provided with a switch for controlling the winding device. The fixed seat 3 is installed on the right side of the control unit 2 and the winding base 4 is arranged on the rear side of the fixed seat 3.

[0054] An adjusting frame 8 is provided on the upper side of the fixed base 3. Inside the adjusting frame 8 is a feeding roller group 9 for feeding spring steel wire raw materials. Grooves are provided on both the left and right sides of the adjusting frame 8, and adjusting sleeves 12 are movably disposed within these grooves. A fixing spring 13 is fixedly connected between the upper side of the adjusting sleeve 12 and the adjusting frame 8. Fixing brackets 14 are fixedly installed on both the left and right sides of the adjusting frame 8, and are located outside the adjusting sleeves 12. A sliding rheostat 15 is fixedly installed on the fixing bracket 14, and a sensing element 151 is slidably mounted on the sliding rheostat 15. The sensing element 151 is electrically connected to the sliding rheostat 15. A connecting piece 1 is provided between the sensing element 151 and the adjusting sleeve 12. 6. When the diameter of the steel wire material is large, the upper feed roller 92 drives the induction plate 151 to move a longer distance, and the sliding distance of the induction plate 151 is also longer, which causes the kinetic energy output of the heating rod 20 to increase simultaneously. Since the diameter of the steel wire material is large, its rigidity is also increased simultaneously, which makes the heating rod 20 strengthen the heat output and improve the heat treatment effect on the steel wire material. When the diameter of the steel wire material is small, the upper feed roller 92 drives the induction plate 151 to move a shorter distance, and the sliding distance of the induction plate 151 is also shorter, which causes the kinetic energy output of the heating rod 20 to decrease simultaneously. Since the diameter of the steel wire material is small, its rigidity is also weakened simultaneously, which makes the heating rod 20 reduce the heat output.

[0055] A stabilizing base plate 5 is fixedly installed inside the fixed base 3. Two stabilizing grooves 51 are opened on the upper side of the stabilizing base plate 5. A movable block 6 is slidably installed on the top of the stabilizing base plate 5. Two stabilizing sliders 61 are fixedly installed on the bottom of the movable block 6, and the stabilizing sliders 61 are located in the stabilizing grooves 51. The movable block 6 is slidably installed with the stabilizing base plate 5 by means of the stabilizing sliders 61. During the process of the movable block 6 moving by screwing with the movable screw 71, the movable block 6 simultaneously drives the stabilizing sliders 61 to slide in the stabilizing grooves 51 above the stabilizing base plate 5, and the stabilizing grooves 51 effectively limit the stabilizing sliders 61.

[0056] A drive mechanism 7 is provided on the left side of the fixed base 3. A movable screw 71 is fixedly connected to the right side of the drive mechanism 7 via its output end. The movable screw 71 is located directly above the stable base plate 5. A hole is opened in the movable block 6, and an internal thread is opened on the inner wall of the hole. The movable screw 71 is threadedly engaged with the internal thread of the hole inside the movable block 6 via its external thread. The drive mechanism 7 drives the movable screw 71 to rotate. The movable screw 71 and the movable block 6 are threaded together and push them and the adjusting frame 8 to move synchronously. As the winding rod 19 drives the steel wire material to wind the spring, the adjusting frame 8 also drives the steel wire material to move synchronously with the winding operation.

[0057] The feed roller assembly 9 includes a lower feed roller 91 and an upper feed roller 92. The upper feed roller 92 is located directly above the lower feed roller 91. A movable shaft 10 is fixedly installed at the central axis of both the lower feed roller 91 and the upper feed roller 92.

[0058] The lower feed roller 91 and the upper feed roller 92 are the same size, and the diameters on the left and right sides of the lower feed roller 91 and the upper feed roller 92 are larger than the middle diameter. By making the diameters on the left and right sides of the upper feed roller 92 and the lower feed roller 91 larger than the middle diameter, it is beneficial to limit the feeding of the steel wire material, lock it in the middle and keep it in the center position, and at the same time avoid the possibility of the steel wire material shifting during the feeding process.

[0059] Fixed sleeves 11 are fixedly installed on both the left and right sides of the adjusting frame 8. The lower feed roller 91 is movably connected to the fixed sleeve 11 via the movable shaft 10, and the upper feed roller 92 is movably connected to the adjusting sleeve 12 via the movable shaft 10. The setting of the fixed sleeve 11 facilitates the installation of the lower feed roller 91, and the setting of the adjusting sleeve 12 facilitates the installation of the upper feed roller 92.

[0060] A fixing clip 81 is fixedly installed on the inner wall of the groove of the adjusting frame 8. Adjusting slots 121 are opened on both the front and rear sides of the adjusting sleeve 12, and the size of the adjusting slots 121 is consistent with the size of the fixing clip 81. The fixing clip 81 is located in the adjusting slot 121. The upper feed roller 92 is moved upward by the steel wire material, which drives the adjusting sleeve 12 to slide on the adjusting frame 8. The stability of the adjusting sleeve 12 and the upper feed roller 92 during movement can be ensured by the fixing clip 81 engaging in the adjusting slot 121.

[0061] A mounting base 17 is fixedly installed on the upper side of the winding base 4. A winding motor 18 is provided on the left side of the mounting base 17. The winding motor 18 is fixedly connected to the winding rod 19 on the right side of the mounting base 17, which winds the spring steel wire material, through its output end.

[0062] A limiting member 191 for limiting the adjustment structure is fixedly installed at the right end of the winding rod 19, and a fixing mechanism 192 for fixing the spring steel wire raw material is fixedly installed on the upper side of the winding rod 19.

[0063] The winding rod 19 has an inner cavity, and a heating rod 20 is installed in the inner cavity. The outer wall of the heating rod 20 is in contact with the inner wall of the winding rod 19. The winding rod 19 is rotated by the output end of the winding motor 18. The winding rod 19 is used to wind the steel wire material. At the same time, the heating rod 20 generates heat and is transferred to the steel wire material along the winding rod 19 by the control unit 2. The rigidity of the steel wire material can be reduced by heat treatment.

[0064] The upper side of the winding base 4 is provided with a fixed bracket 21 and an adjusting bracket 22, and both the fixed bracket 21 and the adjusting bracket 22 are located on the right side of the mounting base 17, with the adjusting bracket 22 located on the right side of the fixed bracket 21.

[0065] The fixed bracket 21 and the adjusting bracket 22 are both sleeved on the outside of the winding rod 19. The fixed bracket 21 and the adjusting bracket 22 are fixedly connected to the winding rod 19 by bearings. The bottom of the fixed bracket 21 is fixedly connected to the upper side of the winding base 4. The adjusting bracket 22 slides on the winding rod 19 and the spring length is effectively adjusted, which is beneficial for adjusting the spring according to different needs.

[0066] An adjustment assembly 23 is provided on the upper side of the winding base 4 and directly below the winding rod 19. The adjustment assembly 23 includes an electric telescopic device 231, a telescopic rod 232 and a mounting component 233.

[0067] The electric telescopic device 231 is located directly below the winding rod 19. A telescopic rod 232 is fixedly installed on the right side of the electric telescopic device 231. An installation component 233 is fixedly installed at the end of the telescopic rod 232 away from the electric telescopic device 231. The upper side of the installation component 233 is fixedly connected to the bottom of the adjusting bracket 22. Under the control of the control unit 2, the electric telescopic device 231 generates kinetic energy and uses the telescopic rod 232 to push the installation component 233 to move. During the movement of the installation component 233, the adjusting bracket 22 moves synchronously, causing the adjusting bracket 22 to slide on the winding rod 19.

[0068] An adjusting slide rod 24 is fixedly installed on the upper side of the base 4 and on both the front and rear sides of the adjusting assembly 23. An adjusting slider 241 is slidably installed on the adjusting slide rod 24. The upper side of the adjusting slider 241 is fixedly connected to the bottom of the adjusting bracket 22. When the adjusting bracket 22 moves, it simultaneously drives the adjusting slider 241 to slide synchronously on the adjusting slide rod 24.

[0069] The specific usage and function of this embodiment are as follows:

[0070] Working principle: A spring is a mechanical part that uses its own deformation to generate force or store energy. It is used for buffering, shock absorption, and controlling mechanical movement. The production of a spring requires winding steel wire into a spring. Currently, in use, the length of the spring needs to be adjusted first. Under the control of the control unit 2, the electric telescopic device 231 generates kinetic energy and uses the telescopic rod 232 to push the mounting part 233 to move. During the movement of the mounting part 233, the adjusting bracket 22 moves synchronously, causing the adjusting bracket 22 to slide on the winding rod 19, thus realizing the effective adjustment of the spring length. This allows the spring to be adjusted according to different needs. During the movement of the adjusting bracket 22, the adjusting slider 241 also slides synchronously on the adjusting slide rod 24. This setting can effectively enhance the stability of the adjusting bracket 22 during movement and further improve its performance.

[0071] After the spring processing length is adjusted, the spring steel wire material is passed between the upper feed roller 92 and the lower feed roller 91. Under the control of the control unit 2, the fixing mechanism 192 on the winding rod 19 fixes one end of the steel wire material. After the steel wire material is firmly fixed, the winding motor 18 and the drive mechanism 7 are started. The output end of the winding motor 18 drives the winding rod 19 to rotate, and the winding rod 19 winds the steel wire material. At the same time, the drive mechanism 7 drives the movable screw 71 to rotate. The movable screw 71 and the movable block 6 are screwed together and push them and the adjusting frame 8 to move synchronously. As the winding rod 19 drives the steel wire material to wind the spring, the adjusting frame 8 also moves the steel wire material synchronously with the winding operation. This setting can improve the spring winding effect and avoid the possibility of the steel wire material getting stuck or repeatedly accumulating.

[0072] Furthermore, when the winding rod 19 drives the steel wire material to wind the spring, the heating rod 20 generates heat through the control of the control unit 2, and the heat is transferred to the steel wire material along the winding rod 19. By heat-treating the steel wire material, the rigidity of the steel wire material can be reduced, while the winding effect of the steel wire material can be improved. Moreover, the spring after heat treatment and winding can further improve its mechanical properties. In addition, during the process of the movable block 6 and the movable screw 71 engaging and moving, the movable block 6 simultaneously drives the stabilizing slider 61 to slide in the stabilizing groove 51 above the stabilizing base plate 5. The stabilizing groove 51 limits the stabilizing slider 61, which can further ensure the stability of the movable block 6 and the adjusting frame 8 when they move.

[0073] Furthermore, when the spring steel wire material passes through the feed roller group 9, if the diameter of the steel wire material is large, when it passes between the upper feed roller 92 and the lower feed roller 91, the steel wire material pushes the upper feed roller 92 to move upward, and drives the adjusting sleeve 12 to slide on the adjusting frame 8. The stability of the adjusting sleeve 12 and the upper feed roller 92 during movement can be ensured by the fixing clip 81 engaging in the adjusting clip groove 121. At the same time, the adjusting sleeve 12 moves upward and squeezes the fixing spring 13. Based on the reaction of the fixing spring 13, the upper feed roller 92 squeezes the steel wire material. Moreover, by making the diameters on the left and right sides of the upper feed roller 92 and the lower feed roller 91 larger than the middle diameter, it is beneficial to limit the feeding of the steel wire material, locking it in the middle and always keeping it in the center position. At the same time, it can avoid the possibility of the steel wire material deviating during the feeding process. Furthermore, this setting can adjust the feeding according to the steel wire material of different diameters, further improving its performance.

[0074] Furthermore, during the upward movement of the adjusting sleeve 12, the connecting piece 16 drives the induction plate 151 to slide on the sliding rheostat 15. This device sets the sliding distance of the induction plate 151 inversely proportional to the internal resistance of the sliding rheostat 15. Since the internal resistance of the sliding rheostat 15 is inversely proportional to the current, the sliding distance is directly proportional to the current. The sliding rheostat 15 is electrically connected to the heating rod 20. At this time, when the diameter of the steel wire material is large, the upper feed roller 92 drives the induction plate 151 to move a longer distance, and the sliding distance of the induction plate 151 is also longer, causing the kinetic energy output of the heating rod 20 to increase synchronously. Because the diameter of the steel wire material is large, this indicates that its... The rigidity is also increased simultaneously, which makes the heating rod 20 strengthen the heat output and improve the heat treatment effect on the steel wire material. When the diameter of the steel wire material is small, the moving stroke of the upper feed roller 92 driving the induction plate 151 is shorter, and the sliding distance of the induction plate 151 is also shorter, which causes the kinetic energy output of the heating rod 20 to decrease simultaneously. Since the diameter of the steel wire material is small, it means that its rigidity is also weakened simultaneously, which makes the heating rod 20 reduce the heat output. On the one hand, it ensures the heat treatment effect on the steel wire material, and on the other hand, it can effectively reduce the consumption of electrical energy, thereby avoiding the waste of electrical energy. Moreover, this setting allows it to automatically adjust based on the change of the diameter of the steel wire material, further improving the applicability of the device.
