[0019] Compared with the related art, the spring machine provided by the utility model which can process various spring wires has the following beneficial effects:

[0020] The utility model provides a spring machine which can process various spring wires. When the spring machine is needed to manufacture springs, the rotation speed or stroke of the motor, servo motor and movable frame is programmed through the control interface according to the production requirements, the spring wire is passed through the wire feeding frame on the movable frame, the wire feeding frame is driven by the servo motor to convey the spring wire, and the motor drives the reel to coil the spring wire. Each coiling operation requires resetting the limit plate, the spring wire is conveyed between the limit plate and the reel, the motor drives the reel to rotate, the reel and the limit plate cooperate to clamp one end of the spring wire and perform the coiling operation. During this process, the movable frame drives the spring wire to move along the extension direction of the reel through the wire feeding frame, and then the spring wire can be cut. However, this operation may cause the following problems: the limit plate is fixed on the reel, and the gap between the driving wheel and the positioning wheel in the wire feeding frame is fixed. Only spring wire of a specified diameter size can be coiled and conveyed, which cannot meet the needs of processing various spring wires and has low practicality. By setting an adjustment structure, the spring wire is firstly The distance between the limit plate and the winding shaft is adjusted according to the diameter size of the limit plate and the winding shaft, and the adjusting rod is turned, and the adjusting rod drives the limit plate to move upward along the inner wall of the adjusting groove with the help of the thread until the limit plate is away from the winding shaft at an appropriate distance, and then the distance between the positioning wheel and the driving wheel is adjusted.

During this process, the slide plate always slides upward along the fixed frame, and the positioning plate drives the positioning wheel and the auxiliary wheels on the two auxiliary frames to move upward. After the positioning wheel is away from the driving wheel by a certain distance, the spring wire passes through the fixed frame and ensures that the spring wire is located between the positioning wheel and the driving wheel. The positioning rod is rotated in the opposite direction so that the positioning plate drives the positioning wheel to move in the direction close to the driving wheel until the spring wire is fully in contact with the driving wheel and the positioning wheel.

A round rod 86 is fixedly connected to the upper surface of the mounting frame 83. The arc surface of the round rod 86 is slidably connected to the support plate 81. The mounting frame 83 is further limited by the round rod 86, so that the mounting frame 83 is more stable when moving up and down.

[0033] The working principle of a spring machine capable of processing a variety of spring wires provided by the utility model is as follows: when it is necessary to use a spring machine to manufacture springs, the rotation speed or stroke of the motor 3, the servo motor 6, and the movable frame 5 is programmed through the control interface 2 according to production requirements, the spring wire is passed through the wire feeding frame on the movable frame 5, and the servo motor 6 is used to drive the wire feeding frame to convey the spring wire, and the motor 3 drives the reel 4 to coil the spring wire, and each coiling operation requires resetting the limit plate 703, and the spring wire is conveyed between the limit plate 703 and the reel 4, and the motor 3 drives the reel 4 to rotate, and the reel 4 and the limit plate 703 cooperate to clamp one end of the spring wire and perform a coiling operation, during which the movable frame 5 drives the spring wire to extend along the reel 4 through the wire feeding frame. 703 is moved in the same direction as the reel 4, and then the spring wire can be cut. However, this operation will have the following problems: the limit plate 703 is fixed on the reel 4, and the gap between the driving wheel 706 in the wire feeding frame and the positioning wheel 710 is fixed. It can only curl and convey spring wires of specified diameters, which cannot meet the needs of processing a variety of spring wires and has low practicality. By setting the adjustment structure 7, the distance between the limit plate 703 and the reel 4 is adjusted according to the diameter of the spring wire, and the adjustment rod 702 is rotated. The adjustment rod 702 drives the limit plate 703 to move upward along the inner wall of the adjustment groove 701 with the help of the thread until the limit plate 703 is away from the reel 4 at a suitable distance, and then the spacing between the positioning wheel 710 and the driving wheel 706 is adjusted. The positioning rod 70 is rotated first. 7. The positioning rod 707 moves upward along the fixed frame 705 with the help of the thread, and the positioning rod 707 drives the positioning plate 708 to move upward. During this process, the slide plate 709 always slides upward along the fixed frame 705, and the positioning plate 708 drives the positioning wheel 710 and the auxiliary wheels 712 on the two auxiliary frames 711 to move upward. After the positioning wheel 710 is away from the driving wheel 706 for a certain distance, the spring line is passed through the fixed frame 705, and it is ensured that the spring line is located between the positioning wheel 710 and the driving wheel 706, and then the positioning rod 707 is rotated in the opposite direction, so that the positioning plate 708 drives the positioning wheel 710 to move in the direction close to the driving wheel 706 until the spring line is fully in contact with the driving wheel 706 and the positioning wheel 710, wherein the pulley 704 is used to reduce the limit plate 703 and the positioning wheel 710. The friction between the inner walls of the adjusting groove 701 makes the limit plate 703 move more smoothly along the adjusting groove 701, and the friction between the driving wheel 706 and the positioning wheel 710 is increased by the anti-slip pad 713, so that the transmission effect of the driving wheel 706 and the positioning wheel 710 when sending the wire is better. With reference to the scale 714 on the slide plate 709, the spacing between the positioning wheel 710 and the driving wheel 706 is adjusted to provide convenience for the user. The spring wire is further limited by the auxiliary tube 715 to make the spring wire more stable when moving, so that the spacing between the limit plate 703 and the reel 4 is changed by operating the adjusting rod 702, and the spacing between the positioning wheel 710 and the driving wheel 706 is changed by operating the positioning rod 707, thereby realizing the curling and wire sending operations of spring wires of different diameters.Suitable for processing spring wires of various diameters.

[0034] The spring wire needs to be cut during the production process of the spring wire, and the manual operation is inefficient. By setting the auxiliary structure 8, when the spring wire is moved into the support plate 81 under the drive of the mobile frame 5, the electric push rod 82 is started, and the electric push rod 82 drives the cutter 84 to move downward through the mounting frame 83 until the cutter 84 cuts the spring wire. After the cutter 84 is worn out after long-term use, the screw rod 85 is rotated, and the screw 85 moves along the mounting frame 83 in a direction away from the cutter 84 with the help of the thread. At this time, the cutter 84 can be slid out of the mounting frame 83, and the cutter 84 is slid into the mounting frame 83 after the maintenance is completed. The screw 85 is rotated in the opposite direction, and the screw 85 moves in the direction of the approaching cutter 84 until the cutter 84 is squeezed. The mounting frame 83 is further limited by the round rod 86, so that the mounting frame 83 is more stable when moving up and down. The spring wire is cut by the electric push rod 82. The cutter 84 and the mounting frame 83 can be conveniently disassembled and assembled, which is convenient for the subsequent maintenance and replacement of the cutter 84.
