Description

Technical Field

[0001] This application relates to the field of spring coil opening machines, and more particularly to a spring coil opening machine. Background Technology

[0002] As a type of spring used to withstand pressure, a compression spring requires a certain pitch between its two sections so that the compression spring can convert the pressure of the load on the compression spring into the elastic potential energy of the spring itself.

[0003] Currently, Chinese utility model patent CN214720209U discloses a spring opening machine, including a frame, a conveying mechanism, a conveying roller and a driving component. Two conveying rollers are used to drive the spring to rotate, and the driving component is used to drive the conveying roller to rotate. A first bracket is slidably mounted on the frame, and a second bracket is slidably mounted on the first bracket. The second bracket is rotatably mounted with an opening wheel. A lead screw is rotatably mounted on the frame, passing through the first bracket and threadedly engaging with it. The first bracket is equipped with a hydraulic cylinder connected to the second bracket. This application facilitates the adjustment of the hydraulic cylinder's stroke.

[0004] Since the distance between the two conveyor rollers is the same, the diameter of the spring is related to the contact position between the conveyor rollers and the spring. The contact point distance between the large-diameter spring and the two conveyor rollers is smaller than the contact point distance between the small-diameter spring and the two conveyor rollers. The stability of the object is positively correlated with the width of the supporting base. Furthermore, when the conveyor rollers are rotating, the large-diameter spring, which was originally in a stable state, is more difficult to maintain stability. Therefore, when the distance between the two conveyor rollers is constant, the stability of the small-diameter spring is better than that of the large-diameter spring. The large-diameter spring is prone to detaching from the conveyor rollers when opening coils, and the adaptability of the coil opening machine is not strong. Utility Model Content

[0005] In order to ensure that springs of different diameters can rotate stably on the coil-opening machine and to improve the adaptability of the coil-opening machine to springs of different diameters, this application provides a spring coil-opening machine.

[0006] This application provides a spring coil opening machine, which adopts the following technical solution:

[0007] A spring unwinding machine includes a frame, two conveying rollers, a control component, an unwinding component, and a drive component. The control component includes two sliding frames and a bidirectional screw. The two sliding frames are slidably connected to the frame in directions that are close to or far apart from each other. The length direction of the bidirectional screw is parallel to the sliding direction of the sliding frames. The bidirectional screw is rotatably connected to the frame. The two sliding frames are threadedly connected to the threaded sections of the bidirectional screw with opposite directions of rotation. The drive component is used to drive the two conveying rollers to rotate in the same direction. The unwinding component is used to perform an unwinding operation on the spring supported by the conveying rollers.

[0008] By adopting the above technical solution and setting a control assembly consisting of two sliding frames and a bidirectional screw, the distance between the two conveying rollers can be adjusted: when the bidirectional screw is rotated, the two sliding frames slide in the direction of approaching or moving away, and the distance between the conveying rollers can be flexibly adjusted according to the size of the spring diameter, thereby changing the width of the spring's support base surface, improving stability and enhancing adaptability.

[0009] Optionally, the driving component includes a rotating rod, two worm gears, two worm sleeves, and a drive motor. The two worm gears correspond to the two conveying rollers, and the worm gears are disposed on one end of the conveying rollers. The length direction of the rotating rod is parallel to the distribution direction of the two sliding frames. The rotating rod is rotatably connected to the frame. The two worm sleeves correspond to the two worm gears, and the worm sleeves are coaxially arranged with the rotating rod. The worm sleeves are slidably connected to the rotating rod. The worm gears mesh with the corresponding worm sleeves. The drive motor is used to drive the rotating rod to rotate.

[0010] By adopting the above technical solution, two worm gears are positioned corresponding to the conveyor rollers, and the worm sleeve is slidably connected to the rotating rod and meshes with the worm gears. When the conveyor rollers adjust their spacing with the sliding frame, the worm sleeve can slide along the rotating rod, always maintaining its meshing with the worm gears. The drive motor drives the conveyor rollers to rotate in the same direction through the rotating rod, worm sleeve, and worm gear transmission, ensuring stable power transmission when the spacing changes, achieving compatibility between spacing adjustment and power transmission, and improving the operational stability of the equipment.

[0011] Optionally, the sliding frame is provided with a cover for covering the worm gear and worm sleeve.

[0012] By adopting the above technical solution, when there is oxide scale, rust layer or coating on the spring surface, the coating may peel off and the oxide scale may break during the opening process, causing non-metallic debris to fly. When the debris comes into contact with the worm gear, it will easily lead to wear of the parts and reduce the life of the worm gear. The cover also reduces the operator's accidental contact and reduces safety hazards.

[0013] Optionally, the cover is provided with lubrication holes for easy refueling.

[0014] By adopting the above technical solution, the cover is opened with lubrication holes, and lubricant can be added to the meshing part of the worm gear and worm sleeve without removing the cover. This simplifies the lubrication operation process, ensures timely lubrication, reduces component wear caused by insufficient lubrication, and improves the convenience of equipment maintenance.

[0015] Optionally, the lubrication hole is threaded, and the lubrication hole can be sealed with bolts.

[0016] By adopting the above technical solution, the lubrication hole is threaded and sealed with bolts. In the non-lubricated state, it can prevent dust, oil and other impurities from entering the cover through the lubrication hole, keep the worm gear meshing environment clean, and at the same time avoid lubricant evaporation or contamination, ensuring the durability of the lubrication effect.

[0017] Optionally, the opening ring assembly includes a fine-tuning component, a mounting frame, a cylinder, a sliding plate, and an opening ring wheel for opening the spring. The mounting frame is slidably connected to the frame in a vertical direction. The fine-tuning component is used to adjust the height difference between the mounting frame and the conveyor roller. The cylinder is vertically arranged, and the cylinder body is disposed on the mounting frame. The sliding plate is disposed on the piston rod of the cylinder, and the opening ring wheel is rotatably connected to the sliding plate.

[0018] By adopting the above technical solution, the height difference between the mounting frame and the conveyor roller is adjusted by the fine-tuning component to adapt to the initial opening height of springs with different diameters; the cylinder drives the sliding plate and the opening wheel to flexibly adjust the opening pressure to adapt to different spring stiffnesses. The dual adjustment realizes the opening adaptation of springs of different specifications and ensures the consistency of opening quality.

[0019] Optionally, the fine-tuning component includes a fine-tuning screw and a handle. The length direction of the fine-tuning screw is parallel to the sliding direction of the mounting bracket. The fine-tuning screw is rotatably connected to the frame. The mounting bracket is threadedly connected to the fine-tuning screw. The handle is disposed at one end of the fine-tuning screw.

[0020] By adopting the above technical solution, the rotating handle can drive the mounting bracket to move vertically and precisely through the rotation of the screw, achieving precise height adjustment. The operation is simple and intuitive, making it easy to quickly adapt to different spring height requirements, ensuring accurate positioning of the opening wheel, and improving the opening accuracy.

[0021] Optionally, the open-loop assembly further includes several linkage rods, the length direction of which is parallel to the sliding direction of the sliding plate. One end of each linkage rod is disposed on the sliding plate, and the other end of each linkage rod extends out of the mounting bracket.

[0022] By adopting the above technical solution, the linkage rod is set along the sliding direction of the sliding plate, with one end connected to the sliding plate and the other end passing through the mounting bracket. It guides the movement of the sliding plate, prevents the sliding plate from deviating or shaking when driven by the cylinder, ensures the stability of the opening wheel's movement trajectory, reduces opening error, and improves opening accuracy and consistency.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The control components of the bidirectional screw and sliding frame enable flexible adjustment of the distance between the two conveying rollers: for large-diameter springs, the distance can be increased to widen the support base, and for small-diameter springs, the distance can be decreased to ensure stable support. This solves the problem of stable transmission of springs of different diameters and greatly improves the adaptability of the coil opening machine to springs of various specifications.

[0025] 2. The transmission failure problem after the spacing adjustment is solved by the drive structure of the rotating rod, worm sleeve and worm wheel. The worm sleeve can slide along the rotating rod and always maintain engagement with the worm wheel that moves with the sliding frame. The drive motor transmits power stably through the rotating rod, ensuring that the same direction can be achieved no matter how the spacing of the conveying rollers changes, ensuring the stable delivery of the spring during the opening process and improving the reliability of the equipment operation.
