[0018] This application provides an automatic spiral spring winding device that effectively solves the technical problems in existing spiral spring winding devices, such as the need for continuous operation of the cooling equipment, which leads to energy waste and equipment damage due to continuous water cooling, and the subsequent decrease in cooling effect due to the increased temperature of the coolant during continuous water cooling. This device, through the cooperation of a temperature detection device 4, a suction pump 33, and a cooling coil 32, monitors the temperature of the arc-shaped shaping part 2 in real time when it is shaping and winding the constraint steel strip, and only starts cooling when the temperature exceeds the threshold, thus avoiding energy waste and equipment damage caused by continuous water cooling.

[0019] Example

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution described in this application effectively solves the technical problems in existing spiral spring winding devices, where the cooling equipment needs to be continuously started, continuous water cooling causes energy waste and equipment damage due to overcooling, and continuous water cooling leads to an increase in coolant temperature, resulting in a decrease in subsequent cooling effect. The overall concept is as follows: An automatic spiral spring winding device includes a production stand 1, on which a winding mechanism for winding spiral springs is provided. A cooling mechanism for cooling the winding mechanism is used on the production stand 1. The winding mechanism includes a forming table 11 and an arc-shaped shaping component 2. The cooling mechanism includes a cooling box 3 and a temperature detection device 4. The forming table 11 is fixedly installed on the side end of the production stand 1, and the arc-shaped shaping component... 2 is located at the side end of the forming table 11, the cooling box 3 is fixedly installed at the upper end of the production stand 1, the temperature detection device 4 is located at the upper end of the cooling box 3, the side end of the forming table 11 is fixedly installed with a fixed support rod 13, and the side end of the forming table 11 is fixedly installed with a guide rack 12. In the working process of the spiral spring winding device, the production stand 1 serves as the core bearing platform. The guide rack 12 first guides the straightened spring steel strip to accurately enter the forming area forming table 11. The feeding path and initial tension of the steel strip are controlled by the adjustable roller. Then, the arc-shaped shaping part 2 of the shaping rod can assist in spiral winding, constraining the steel strip to adhere to the inner wall of the arc-shaped shaping part 2 for winding. After winding to a certain number of turns, the wound spiral spring can be cut.

[0021] A connecting rod 22 is fixedly installed between the arc-shaped shaping part 2 and the fixed support rod 13. Multiple arc-shaped through slots 21 are opened through the side end of the arc-shaped shaping part 2. The upper end of the cooling box 3 is fitted with a box cover 31. The inner side wall of the cooling box 3 is equipped with a suction pump 33. When the threshold of the arc-shaped shaping part 2 exceeds a certain temperature threshold, the temperature detection device 4 and the suction pump 33 are wirelessly connected. The temperature detection device 4 will drive the suction pump 33 to pump the coolant in the cooling box 3 into the cooling coil 32.

[0022] A cooling coil 32 is fixedly installed at the upper end of the suction pump 33. The cooling coil 32 is wound around the inner wall of the arc-shaped groove 21. The cooling coil 32 is located on the inner wall of the arc-shaped groove 21. When the coolant passes through the arc-shaped groove 21 in the arc-shaped shaping part 2, it will cool the arc-shaped shaping part 2. When the arc-shaped shaping part 2 is cooled to a certain temperature threshold, the temperature detection device 4 can drive the suction pump 33 to stop and stop cooling the arc-shaped shaping part 2. This process is repeated to ensure the continuous generation of the spiral spring.

[0023] Temperature detection device 4 is fixedly installed on the upper end of box cover 31. Temperature probe 41 is fixedly installed on the upper end of temperature detection device 4. Temperature probe 41 is in contact with the lower end of arc-shaped shaping part 2. During the reciprocating production of spiral spring, the constraint steel strip and arc-shaped shaping part 2 are always in a state of friction. The temperature of arc-shaped shaping part 2 will gradually rise during continuous production. Excessive temperature may affect the forming production of constraint steel strip. Users can set a certain temperature threshold on temperature detection device 4, and temperature probe 41 can detect the temperature of arc-shaped shaping part 2 in real time.

[0024] To address the problems existing in the prior art, this utility model provides an automatic winding device for spiral springs. This device, through the cooperation of a temperature detection device 4, a suction pump 33, and a cooling coil 32, monitors the temperature of the arc-shaped shaping part 2 in real time when it is shaping and winding the constraint steel strip, and only starts cooling when the temperature exceeds the threshold. This avoids energy waste and equipment overcooling damage caused by continuous water cooling.

[0025] Production stand 1: As the core load-bearing structure of the automatic winding device for spiral springs, it provides a stable installation foundation for the winding mechanism and the cooling mechanism, and supports components such as the forming table 11 and the cooling box 3.

[0026] Forming table 11: Fixedly installed at the end of the production stand 1, it is a working platform for winding spiral springs and provides operating space for forming spring steel strips.

[0027] Guide frame 12: Fixed to the side end of the forming table 11, used to guide the straightened spring steel strip into the forming area accurately. The feeding path and initial tension of the steel strip are controlled by adjustable rollers to ensure that the steel strip can accurately enter the winding station.

[0028] Fixed support rod 13: It is fixedly installed on the side end of the forming table 11 and cooperates with the connecting rod 22 to support the arc-shaped shaping part 2.

[0029] Arc-shaped shaping component 2: Located at the end of the forming table 11, it assists the spring steel strip in spiral winding, constrains the steel strip to be tightly wrapped against its inner side wall, so that the steel strip is formed into a spiral spring.

[0030] Arc-shaped through groove 21: It is opened through the end of the arc-shaped shaped part 2 and is used to install the cooling coil 32.

[0031] Connecting rod 22: Connects the arc-shaped shaping part 2 and the fixed support rod 13, and serves to stabilize the arc-shaped shaping part 2.

[0032] Cooling box 3: Fixedly installed on the upper end of production stand 1, used to store coolant and provide cooling medium for the cooling system.

[0033] Cover 31: Sleeves on the upper end of the cooling box 3 to seal the cooling box 3, prevent coolant from evaporating or impurities from entering, and provide an installation position for the temperature detection device 4.

[0034] Cooling coil 32: Fixed to the upper end of suction pump 33, it is connected to the inner wall of arc-shaped through groove 21. When suction pump 33 is working, coolant flows in cooling coil 32 and cools arc-shaped part 2 through heat exchange to ensure that its working temperature is within a reasonable range.

[0035] Suction pump 33: Installed on the inner wall of the cooling box 3, wirelessly connected to the temperature detection device 4. According to the instructions of the temperature detection device 4, the pump draws the coolant in the cooling box 3 into the cooling coil 32, controls the circulation of the coolant, and realizes on-demand cooling of the arc-shaped part 2.

[0036] Temperature detection device 4: Fixedly installed on the upper end of the box cover 31, used to monitor the temperature of the arc-shaped shaping part 2 and set the temperature threshold.

[0037] Temperature probe 41: Fixed to the upper end of temperature detection device 4, in contact with the lower end of arc-shaped shaping part 2, to detect the temperature of arc-shaped shaping part 2 in real time.

[0038] Working principle:

[0039] In the workflow of the spiral spring winding device, the production stand 1 serves as the core support platform. The guide frame 12 first guides the straightened spring steel strip precisely into the forming table 11 of the forming area. Adjustable rollers control the feeding path and initial tension of the steel strip. Subsequently, the arc-shaped shaping part 2 of the shaping rod assists in spiral winding, constraining the steel strip to adhere tightly to the inner wall of the arc-shaped shaping part 2 for winding. After winding to a certain number of turns, the wound spiral spring can be sheared. During the reciprocating production of the spiral spring, the constrained steel strip and the arc-shaped shaping part 2 are always in a state of friction. During continuous production, the temperature of the forming component 2 will gradually increase. Excessive temperature may affect the forming of the constraint steel strip. Users can set a certain temperature threshold on the temperature detection device 4. The temperature probe 41 detects the temperature of the arc-shaped forming component 2 in real time. When the temperature threshold of the arc-shaped forming component 2 exceeds a certain threshold, the temperature detection device 4 and the suction pump 33 are wirelessly connected. The temperature detection device 4 will drive the suction pump 33 to pump the coolant from the cooling tank 3 into the cooling coil 32. The cooling coil 32 is located on the inner wall of the arc-shaped through groove 21, cooling... When the liquid passes through the arc-shaped groove 21 within the arc-shaped shaping component 2, it cools the arc-shaped shaping component 2. When the arc-shaped shaping component 2 cools to a certain temperature threshold, the temperature detection device 4 drives the suction pump 33 to stop, ceasing further cooling of the arc-shaped shaping component 2. This process repeats to ensure the continuous generation of the spiral spring. In existing spiral spring winding devices, the cooling equipment needs to be continuously started. Continuous water cooling will cause energy waste and equipment overcooling damage. Furthermore, continuous water cooling will cause the coolant temperature to rise, leading to a decrease in subsequent cooling effects. The device is equipped with a temperature detection device 4, a suction pump 33, and a cooling coil 32. When the arc-shaped shaping part 2 is shaping and winding the constraint steel strip, the temperature detection device 4 monitors the temperature of the arc-shaped shaping part 2 in real time and only starts cooling when the temperature exceeds the threshold. This avoids energy waste and equipment damage caused by continuous water cooling, and also cools the arc-shaped shaping part 2 to prevent high temperature from affecting the forming of the constraint steel strip. This ensures that the spring winding is within the safe temperature range for elastic deformation throughout the entire process. At the same time, it avoids the lag of relying on manual experience to judge temperature control and ensures stable and continuous operation of the equipment.

[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
