Abstract
Description
Technical Field
[0001] This utility model relates to the field of spring processing technology, and in particular to a cutting device for spring processing. Background Technology
[0002] A spring is a mechanical component that can store and release energy. It is widely used in various mechanical equipment and daily necessities. When springs are being cut, clamping and fixing them is a very important step. It not only ensures the safety of the cutting process, but also improves the quality and efficiency of the cutting.
[0003] A search revealed Chinese patent publication number CN222569126U, which discloses a cutting device for processing mechanical springs. This patent involves placing the spring to be cut on a fixed base, fixing one end of the spring and making the cutting section abut against a positioning sleeve, then cutting the section and collecting the fallen springs. This device has certain problems: the movable end of the spring abuts against the inside of the positioning sleeve, but the positioning sleeve is of a fixed size, which is inconvenient for limiting springs of various diameters, resulting in the spring being in an unstable state during cutting.

[0026] The present invention will be further described below with reference to the accompanying drawings:
[0027] like Figures 1-5 As shown, a cutting device for spring processing includes a base plate 101. A fixing frame 102 is fixedly connected to the upper end of one side of the base plate 101. A fixing tube 301 is provided on the side of the base plate 101 away from the fixing frame 102. A fixing mechanism is provided on the fixing frame 102, and the fixing mechanism includes a fixing shaft 401.
[0028] The fixed shaft 401 is fixedly connected to the side of the fixed frame 102 near the fixed tube 301. The fixed tube 301 is coaxial with the fixed shaft 401. A collar 402 is slidably connected to the fixed shaft 401. Multiple electric push rods 403 are fixedly connected between the collar 402 and the fixed frame 102. Multiple movable arms 404 are hinged to the collar 402. Multiple connecting rods 405 are hinged to the end of the fixed shaft 401 away from the fixed frame 102. The end of the connecting rod 405 near the collar 402 is hinged to the middle of the movable arm 404. An inner support plate 406 is rotatably connected to the end of the movable arm 404 near the fixed tube 301.
[0029] A sliding support plate 502 is provided on the side of the inner support plate 406 away from the fixed frame 102. A cutting assembly is provided between the inner support plate 406 and the sliding support plate 502. In use, one end of the spring is fixed inside the fixed tube 301, and the other end of the spring is sleeved on the outside of multiple inner support plates 406. Then, the electric push rod 403 drives the collar 402 to move towards the fixed tube 301, so that the movable arm 404 rotates around the hinge axis of the collar 402. At the same time, the connecting rod 405 pushes the movable arm 404, so that the end of the movable arm 404 away from the collar 402 is away from the fixed axis 401, thereby making multiple inner support plates 406 abut against the inside of the spring, which is convenient for limiting the springs of various specifications and enhancing the stability of subsequent spring cutting.
[0030] A connecting component is provided between the sliding tray 502 and the fixed frame 102. The sliding tray 502 is U-shaped with the opening facing upwards. Symmetrical locking knobs 503 are threadedly connected to the front and rear sides of the sliding tray 502.
[0031] The connecting assembly includes a connecting frame 501, a connecting block is fixedly connected between the connecting frame 501 and the fixing frame 102, a sliding plate 502 is slidably connected to the connecting frame 501, and the front and rear sides of the connecting frame 501 are slidably connected to the locking knob 503. The height of the sliding plate 502 is adjusted so that the sliding plate 502 abuts against the lower end of the spring. Then, the locking knob 503 is rotated to fix the position of the sliding plate 502.
[0032] A support plate is fixedly connected to the base plate 101. A movable screw 201 is rotatably connected to the support plate. A power motor is fixedly connected to the support plate. The output shaft of the power motor is fixedly connected to the movable screw 201. A movable block 202 is threadedly connected to the movable screw 201. The power motor drives the movable screw 201 to rotate, so that the movable block 202 drives the fixed tube 301 to move on the movable screw 201.
[0033] The fixed tube 301 is fixedly connected to the upper end of the movable block 202. A bidirectional lead screw 302 is rotatably connected inside the fixed tube 301. Symmetrical limiting plates 303 are threadedly connected to both sides of the bidirectional lead screw 302. Rotating the bidirectional lead screw 302 drives the symmetrical limiting plates 303 to move towards each other and abut against the inner side of the spring.
[0034] The fixed tube 301 is threaded with multiple threaded rods 701 on one side near the sliding support plate 502. The multiple threaded rods 701 are evenly distributed around the fixed tube 301. The end of the threaded rod 701 near the limiting plate 303 is fixedly connected to a pressure plate 702. Rotating the threaded rod 701 causes the pressure plate 702 to abut against the outside of the spring.
[0035] The cutting assembly includes a bracket, an electric telescopic rod is fixedly connected to the front end of the bracket, a drive motor 601 is fixedly connected to the front end of the electric telescopic rod, and a cutter head 602 is fixedly connected to the output shaft of the drive motor 601. The drive motor 601 drives the cutter head 602 to rotate, and then the electric telescopic rod drives the cutter head 602 to approach the spring for cutting.
[0036] Working principle: In use, one end of the spring is fixed inside the fixed tube 301. Then, the double-acting screw 302 is rotated to drive the symmetrical limiting plates 303 to move towards each other and abut against the inner side of the spring. Then, the threaded rod 701 is rotated to make the pressure plate 702 abut against the outer side of the spring. Then, the height of the sliding support plate 502 is adjusted so that the sliding support plate 502 abuts against the lower end of the spring. Then, the locking knob 503 is rotated to fix the position of the sliding support plate 502. The other end of the spring is sleeved on the outside of the multiple inner support plates 406. Then, the electric push rod 403... The drive collar 402 moves toward the fixed tube 301, causing the movable arm 404 to rotate around the hinge axis of the collar 402. At the same time, the connecting rod 405 pushes the movable arm 404, causing the end of the movable arm 404 away from the collar 402 to move away from the fixed axis 401. This allows multiple inner support plates 406 to abut against the inner side of the spring, facilitating the limiting of springs of various specifications and enhancing the stability of subsequent spring cutting. Subsequently, the drive motor 601 drives the cutter head 602 to rotate, and the electric telescopic rod drives the cutter head 602 to approach the spring for cutting.
