[0002] In the existing special-shaped spring production process, the traditional lubrication method mostly relies on manual addition of lubricating oil to the winding part.

[0003] Chinese patent application number: CN220073132U, provides a spring winding device. This solution uses the structural setting of the adjustment component. The user rotates the handle to rotate the bidirectional threaded rod, thereby moving the adjustment ring on the two sections of the bidirectional threaded rod, so that the corresponding slider slides in the adjustment groove, thereby adjusting the hinge plate, and then pushing the support plate. At this time, the rear side of the corresponding support plate is slidably connected to the slide groove, making the movement of the support plate more stable. The outer side of the adjustment component is sleeved with a winding outer tube of corresponding size, so that the corresponding support plate is clamped in the clamping slot In the process, the winding outer tube is positioned, and then the user connects the corresponding positioning hole group and the fixing hole group through screws to improve the stability of the installation of the winding outer tube, which is convenient for the staff to operate and use, and convenient for the user to install and adjust the spring winding equipment, and convenient for the user to operate and use. However, this method has many shortcomings. First, it is difficult to accurately control the amount of lubricant added manually, which often leads to excessive or insufficient addition of lubricant, thereby affecting the lubrication effect of the spring and the quality of the finished product. Secondly, manual addition is required for each winding, which undoubtedly increases the operating steps and labor intensity, and reduces production efficiency.

[0004] To this end, we propose a spring winding equipment for producing special-shaped springs. Utility Model Content

[0028] The present invention will be described in further detail below with reference to the accompanying drawings.

[0029] Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0030] Reference Figures 1 to 6 As shown, a spring winding device for producing special-shaped springs in a preferred embodiment of the present invention includes a support frame 1, on which a conveying area 2 for conveying special-shaped springs 11 is installed, which is used to convey the special-shaped spring 11 raw materials to be processed from the raw material warehouse to the loading area 3. A loading area 3 for loading the special-shaped spring 11 is installed on one side of the conveying area 2. The device automatically grabs the special-shaped spring 11 raw materials delivered from the conveying area 2 and places it in a designated position of the winding area 4 through a grasping mechanism such as a robotic arm or a suction cup. A winding area 4 for winding the special-shaped spring 11 is installed on one side of the loading area 3. The winding area 4 is the core area of ​​the equipment and is equipped with a precise winding mechanism and control system. The winding mechanism drives the winding die to wind the special-shaped spring 11 according to preset winding parameters (such as winding diameter, number of turns, angle, etc.) through a motor. The control system is responsible for monitoring the winding process to ensure the accuracy and stability of the winding parameters.

[0031] The winding area 4 is provided with a lubricating assembly for automatically adding lubricating oil to the special-shaped spring 11 during the winding process.

[0032] Specifically, the lubrication assembly includes a support plate, an oil storage tank 5 is fixedly provided on the surface of the support plate, the oil storage tank 5 is used to store lubricating oil, a piston 6 is slidingly provided on the inner wall of the oil storage tank 5, an electric push rod 7 is fixedly provided on the support plate, and the protruding end of the electric push rod 7 is fixed to the piston 6, the end of the oil storage tank 5 away from the piston 6 is connected to the discharge pipe 8, and the end of the oil storage tank 5 close to the discharge pipe 8 is installed with a position sensor 9, which is a photoelectric sensor, which can monitor the position of the piston 6 in the oil storage tank 5 in real time and feed back the position information to the control system.

[0033] When the winding area 4 starts to wind the special-shaped spring 11, the position sensor 9 sends an instruction to start the electric push rod 7. The extended end of the electric push rod 7 starts to push the piston 6 to slide in the oil tank 5. As the piston 6 moves, the lubricating oil in the oil tank 5 is squeezed and squeezed out through the discharge pipe 8, and evenly sprayed onto the special-shaped spring 11 being wound. The position sensor 9 monitors the moving position of the piston 6 in real time and feeds back the data to the control system. When the piston 6 moves to the preset position, the control system sends an instruction to stop the extension of the electric push rod 7, thereby controlling the amount of lubricating oil added.

[0034] In the second preferred embodiment of the present invention, a recovery and filtering component for recovering the lubricating oil is further provided on one side of the lubrication component in the winding area 4. It is responsible for recovering and filtering the lubricating oil that drips or splashes during the winding process to ensure the cleanliness of the production environment and the recycling of the lubricating oil. The recovery and filtering component includes a collecting box 10, which is fixedly arranged on the winding area 4. A spring 11 is fixedly arranged on the inner wall of the collecting box 10, and a filter cotton 12 is fixedly arranged on one end of the spring 11. The filter cotton 12 is movably connected to the inner wall of the collecting box 10. A pump body 13 is fixedly provided on the inner wall of the collecting box 10, and a delivery pipe 14 is connected to one side of the pump body 13. One end of the delivery pipe 14 is connected to the storage tank. The pump body 13 is electrically connected to the control system, and the control system can automatically start or stop the pump body 13 according to the liquid level of the storage tank.

[0035] There are debris discharge openings 15 on both sides of the collection box 10. A slide rail is fixedly provided on one side of the collection box 10 near the debris discharge opening 15. A debris discharge strip 16 is slidably provided on the slide rail. A pull ring 17 is provided at one end of the debris discharge strip 16 to facilitate the staff to pull out the debris discharge strip 16 for cleaning.

[0036] The filter cotton 12 is arranged in an arc shape. The filter cotton 12 is made of high-density, oil-resistant and wear-resistant materials. It can effectively filter out impurities and particulate matter in the lubricating oil. At the same time, the filter cotton 12 is movably connected to the inner wall of the collection box 10, which is convenient for disassembly and replacement. The curvature of the arc-shaped filter cotton 12 matches the inner wall of the collection box 10, and the material of the filter cotton 12 is a special fiber material that is oil-resistant and high-temperature resistant.

[0037] During the process of winding the special-shaped spring 11, dripping or splashing lubricating oil will fall into the collection box 10. As the lubricating oil accumulates, its gravity not only promotes the collection process, but also drives the spring 11 and the filter cotton 12 to slide along the inner wall of the collection box 10. This sliding action not only helps the lubricating oil to be more evenly distributed on the filter cotton 12, thereby improving the filtration efficiency, but also uses the power generated by the sliding to effectively discharge impurities attached to the surface of the filter cotton 12 from the predetermined impurity discharge port 15.

[0038] The filtered lubricating oil is then extracted by the pump body 13 in the collection box 10 and transported back to the oil storage tank 5 through the delivery pipe 14 for reuse in the subsequent winding process. This not only ensures the continuous supply of lubricating oil, but also maximizes the utilization of resources, while reducing environmental pollution and cost waste in the production process.
