Description

Technical Field

[0001] This utility model relates to the field of spring processing technology, specifically to a spring coiling device for spring processing. Background Technology

[0002] A spring is a commonly used industrial metal product. It is helical in shape and is generally installed between different components to provide elasticity or to dampen vibration. Springs come in different sizes for different applications and have parameters such as pitch, stiffness, and number of coils. Springs are manufactured based on these parameters.

[0003] Cylindrical springs are a commonly used type of spring. Their diameter is uniform in the axial direction. Larger cylindrical springs are often used in some large mechanical parts. These springs have a larger wire diameter. During production, the uncooled wire is shaped by winding, which is a combination of rotation and axial movement.

[0004] According to a spring coiling device for spring processing disclosed in the above application (Announcement No.: CN118558891B), when coiling a spring, the spring is formed by simply combining rotation and axial movement. However, the speed of axial movement cannot be controlled during the coiling process. Therefore, during the axial movement, it is very easy for some coils to be too large and the overall coil spacing to be uneven. In order to solve this problem, we propose a spring coiling device for spring processing. Summary of the Invention

[0005] The purpose of this invention is to provide a spring coiling device for spring processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spring coiling device for spring processing, comprising a base plate and a roller for coiling springs. A fixing plate is fixedly installed on the top of the base plate, and a guide hole is provided in the fixing plate. A fixing disk is fixedly installed on the side of the roller, and the fixing disk is rotatably connected to the inner wall of a support plate. A motor is fixedly installed on the side of the support plate, and the output shaft of the motor is fixedly connected to the fixing disk. An electric push rod is provided on the inner wall of the fixing disk, and a clamping plate is fixedly installed at the bottom of the electric push rod. A support frame is fixedly installed on the top of the base plate, and a control component is provided inside the support frame. The control component includes: Spring 1, one end of which is fixedly installed on the inner wall of the support plate, and the other end of which is fixedly installed on the side of the slide plate, and a fixing block is fixedly installed on the side of the slide plate; The movable component is used to uniformly adjust the speed of the coiling spring, thereby buffering the moving speed of the support plate and the roller, ensuring uniform movement, and preventing situations where some coil spacing is too large and the overall coil spacing is uneven due to excessive moving speed.

[0007] Preferably, the movable component includes a crossbar, which is fixedly installed on the top of the support frame. A protrusion is fixedly installed on the side of the crossbar, and the protrusion on the surface of the crossbar can buffer the moving speed of the support plate.

[0008] Preferably, a second motor is fixedly installed on the side of the support frame. The output shaft of the second motor is fixedly connected to a reciprocating lead screw. The reciprocating lead screw passes through the support frame and is rotatably connected to the support frame. The output shaft of the second motor can drive the reciprocating lead screw to perform circular motion within the support frame.

[0009] Preferably, the reciprocating screw is provided with a threaded slider, which is slidably connected to the inner wall of the support frame. The top of the threaded slider is fixedly connected to the bottom of the support plate. When the reciprocating screw rotates inside the support frame, the threaded slider can drive the support plate to slide.

[0010] Preferably, a fixing rod is fixedly installed on the top of the support frame. The fixing rod on the top of the support frame is designed to allow the slide rod to slide within the support plate when it comes into contact with the cut surface of the slide rod.

[0011] Preferably, the inner wall of the support plate is fixedly connected to one end of the second spring, and the other end of the second spring is fixedly installed on the side of the slide rod. The slide rod passes through the support plate and is slidably connected to the support plate. The side of the slide rod is in contact with the inner wall of the support plate. A bell is provided inside the support plate. When the cut surface of the slide rod is no longer in contact, it can spring up from inside the support plate under the action of the second spring.

[0012] Preferably, a knocking rod is fixedly installed on the side of the slide rod, and the front end of the slide rod has a triangular cross-section. When the cross-section of the slide rod is abutted, the knocking rod can be driven to slide within the support plate.

[0013] Compared with the prior art, the present invention provides a spring coiling device for spring processing, which has the following beneficial effects: 1. This spring processing coiling device, equipped with a control component, allows the output shaft of motor two to drive the reciprocating lead screw to rotate within the support frame. The threaded slider, under force, drives the support plate to move laterally. During this lateral movement, the protrusions fixed to the surface of the crossbar abut against the tangential surface of the fixed block. When the tangential surface of the fixed block is abutted, the sliding plate fixed to the surface of the fixed block compresses spring one. Because the surface of the crossbar has multiple sets of protrusions, the tangential surface of the fixed block can abut multiple times, thus buffering the movement speed of the support plate and the roller, ensuring a uniform movement speed, and preventing excessively large partial coil spacing and overall uneven coil spacing due to excessively fast movement.

[0014] 2. The spring coiling device for spring processing is equipped with a movable component. When the support plate moves to the position of the fixed rod, the fixed rod will abut against the tangential surface of the slide rod. When the tangential surface of the slide rod is abutted, the spring can be compressed. When the slide rod moves, the knocking rod fixed to the surface of the slide rod can strike the bell to make it sound, thereby reminding the operator that the spring coiling section has been completed.

[0017] like Figures 1-4As shown, this utility model provides a technical solution: a spring coiling device for spring processing, including a base plate 1 and a roller 4 for coiling springs. A fixing plate 2 is fixedly installed on the top of the base plate 1, and a guide hole 3 is provided in the fixing plate 2. A fixing disk 5 is fixedly installed on the side of the roller 4. The fixing disk 5 is rotatably connected to the inner wall of a support plate 6. A motor 7 is fixedly installed on the side of the support plate 6. The output shaft of the motor 7 is fixedly connected to the fixing disk 5. An electric push rod 9 is provided on the inner wall of the fixing disk 5. A clamping plate 10 is fixedly installed at the bottom of the electric push rod 9. A support frame 11 is fixedly installed on the top of the base plate 1. A control component 8 is provided inside the support frame 11. Includes: spring 81, slide plate 82, fixed block 83, and moving part 84. During the lateral movement of the support plate 6, the protrusion 842 fixed on the surface of the crossbar 841 will abut against the cut surface of the fixed block 83. When the cut surface of the fixed block 83 is abutted, the slide plate 82 fixed on the surface of the fixed block 83 can squeeze the spring 81. Since the surface of the crossbar 841 is provided with multiple sets of protrusions 842, the cut surface of the fixed block 83 can be abutted multiple times, thereby buffering the moving speed of the support plate 6 and the roller 4, and making the moving speed uniform, avoiding the situation that the partial circle spacing is too large and the overall circle spacing is uneven due to the moving speed being too fast.

[0018] The movable component 84 includes a crossbar 841, which is fixedly installed on the top of the support frame 11. A protrusion 842 is fixedly installed on the side of the crossbar 841, and the protrusion 842 on the surface of the crossbar 841 can buffer the moving speed of the support plate 6. A second motor 843 is fixedly installed on the side of the support frame 11. The output shaft of the second motor 843 is fixedly connected to a reciprocating lead screw 844, which passes through the support frame 11 and is rotatably connected to it. The output shaft of the second motor 843 can drive the reciprocating lead screw 844 to perform circular motion within the support frame 11. A threaded slider 845 is provided on the reciprocating lead screw 844, which is slidably connected to the inner wall of the support frame 11. The top of the threaded slider 845 is fixedly connected to the bottom of the support plate 6. When the reciprocating lead screw 844 rotates within the support frame 11, the threaded slider 845 can drive the support plate 6 to slide. A fixing rod 846 is fixedly installed on the top of the support frame 11. The fixing rod 846 is designed to allow the slide rod 849 to slide within the support plate 6 when it comes into contact with the cross-section of the slide rod 849. One end of the second spring 848 is fixedly connected to the inner wall of the support plate 6, and the other end of the second spring 848 is fixedly installed on the side of the slide rod 849. The slide rod 849 passes through the support plate 6 and is slidably connected to the support plate 6. The side of the slide rod 849 is in contact with the inner wall of the support plate 6. A bell 847 is installed inside the support plate 6. When the cross-section of the slide rod 849 is no longer in contact, it can spring out of the support plate 6 under the action of the second spring 848. A knocking rod 840 is fixedly installed on the side of the slide rod 849. The front end of the slide rod 849 has a triangular cross-section. When the cross-section of the slide rod 849 is in contact, it can drive the knocking rod 840 to slide within the support plate 6.

[0019] In this invention, during use, the material is passed through the guide hole 3 in the fixing plate 2 and wound onto the surface of the roller 4. Then, the electric push rod 9 is driven to push the clamping plate 10 downwards, fixing one end of the material. After fixing, motors 7 and 843 are simultaneously activated. Motor 7 drives the fixing plate 5 and the roller 4 to rotate and coil the spring, while motor 843 drives the reciprocating screw 844 to perform circular motion within the support frame 11. When the reciprocating screw 844 rotates, the threaded slider 845 slides along the inner wall of the support frame 11. During the movement of the threaded slider 845, the support plate 6 moves laterally. During the lateral movement of the support plate 6, the protrusion 842 fixed to the surface of the crossbar 841 abuts against the cut surface of the fixing block 83. When the cut surface of the fixing block 83 is abutted, the surface of the fixing block 83... The fixed slide plate 82 can compress the spring 81. Since the surface of the crossbar 841 is provided with multiple sets of protrusions 842, it can repeatedly abut against the cut surface of the fixed block 83, thereby buffering the moving speed of the support plate 6 and the roller 4, and making the moving speed uniform. This avoids the situation where the partial coil spacing is too large and the overall coil spacing is uneven due to the moving speed being too fast. When the support plate 6 moves to the position of the fixed rod 846, the fixed rod 846 will abut against the cut surface of the slide bar 849. When the cut surface of the slide bar 849 is abutted, it can compress the spring 848. When the slide bar 849 moves, the knocking rod 840 fixed on the surface of the slide bar 849 can strike the bell 847 to make it sound, thereby reminding the operator that the spring coiling section has ended and the next operation, cutting the material, is required.

[0020] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
