It is generally installed and connected between different parts to provide elastic force and can also be used to buffer vibration. For different usage scenarios, the size of the spring is different. It has parameters such as pitch, stiffness and number of turns. When producing springs, it is also manufactured according to these parameters. Cylindrical spring is a commonly used type of spring. Its diameter is uniform in the axial direction. In some large mechanical parts, larger cylindrical springs are often used. The wire diameter of this type of spring is larger. During production, the uncooled wire is formed by winding, that is, combined with the spiral The wire is formed by a composite motion of rotation and axial movement; currently, the surface of the formed wire is still doped with many impurities. When it is bent and deformed, some of the impurities will fall off from the surface of the wire. In the current production operation, the fallen impurities are not effectively treated, that is, they are not effectively collected, resulting in a poor workshop environment.

[0029] The principle of implementing the present invention is as follows: the wire used for winding passes through the feed hole on the working cylinder 6, and the fixed cylinder 2 30 and the fixed cylinder 1 28 work, so that the fixed block 29 fixes the end of the wire on the surface of the reel 8 (at this time, the cleaning piece is retracted inside the reel 8), and the winding motor 14 works. Under the gear transmission, the reel 12 and the reel 8 rotate. At the same time, the motor 12 works, the screw rod 13 rotates, and the slide 7 slides. Through the composite movement of rotation and movement, the wire is wound. The limiting cylinder 21 controls the movement of the limiting cylinder 23, so that the limiting cylinder 23 limits the wire. After the winding is completed, the cutting cylinder 4 controls the cutting part 5 to cut the wire, and the cutting area continues to wind. The end wire can be limited and wound on the surface of the reel 8 by the limiting cylinder 23.

[0030] When the wire is being wound, it has plasticity because it has not been completely cooled. When it is deformed, impurities will fall off the surface and fall into the inside of the working cylinder 6. Further, after the winding is completed, the extension screw 33 is rotated by the screw motor 11, and the extension frame 34 is moved, so that the cleaning piece is moved and extended to the outside of the reel 8, and the reel 8 returns to the initial winding position. The spring wound on the surface of the reel 8 is pushed by the inner end of the working cylinder 6, so that the spring moves to the cleaning piece (the fixed block 29 releases the fixation of the wire end) and is supported by the inner support rod 38. Since the radial position of the inner support rod 38 is on the inner side of the spring, the spring is suspended on the fixed oil cylinder 28. By operating the rotating motor 15, the turntable 13 is rotated under the gear transmission, and then the cleaning piece rotates accordingly, that is, the extension frame 34 and the installation As the mounting seat 1 35 and the mounting seat 2 37 rotate, the inner support rod 38 also rotates, and the ball bearings on the inner support rod 38 contact the inner surface of the spring and roll the inner surface of the spring to make impurities on the inner surface fall off. The ball bearings can reduce contact friction and facilitate the vibration of the spring, which is conducive to the falling of impurities; further, the motor 41 can be controlled to work, so that the rotating frame 42 rotates, and the roller 43 pushes the inclined push plate 44 to make the limiting slide 39 and the inner support rod 38 slide, so as to support and fix the inner side of the spring, drive the spring to adjust the angle, so that the inner side of the spring is located in the hanging area, and all-round inner contact rolling is achieved; further, the spring can also be driven to rotate synchronously, and the position of the outer rolling cylinder 18 is controlled by adjusting the electric cylinder 19, so that the outer rolling cylinder 18 contacts the outer surface of the spring, and the outer surface of the spring is rolled to make impurities on the outer surface fall off.

[0031] The impurities are processed by controlling the detachment plate 17 to detach from the bottom of the working cylinder 6 through the detachment cylinder 16, and then driving the motor 24 to work, driving the screw rod 25 to rotate, and the push plate 26 to slide, so as to push the impurities inside the working cylinder 6 to the position of the detachment plate 17, so as to facilitate the subsequent collection and processing of the impurities.
