[0019] Compared with the related art, the spring processing wire twisting mechanism provided by the utility model has the following beneficial effects:
[0020] The utility model provides a spring processing wire twisting mechanism. When the wire twisting mechanism is needed to process the wire into a spring, the control interface is first used to program the driving device and the wire feeding device, and the equipment is started. The wire feeding device first feeds the wire to between the reel and the limit plate, and the driving device drives the mounting post and the reel to rotate. During this process, the limit plate on the mounting post cooperates with the reel to curl one end of the wire. The wire feeding device drives the wire to move in the extension direction of the reel while feeding the wire, and the wire is twisted into a spring shape along the arc surface of the reel. However, this spring processing twisting mechanism has the following problems: the traditional mounting post, limit plate and The reel is one-piece and is prepared according to the diameter of the steel wire and the inner diameter of the spring to be produced. When using steel wires of different diameters to produce springs of different inner diameters, it is necessary to prepare and replace multiple sets of one-piece mounting columns, limit plates and reels, which is cumbersome and costly. By setting an adjustment structure, the adjustment rod is first rotated, and the adjustment rod drives the limit plate to move upward along the adjustment groove with the help of a thread. After leaving a suitable distance, the auxiliary rods on both sides are moved away from the reel. The auxiliary rods drive the limit ring to move along the arc surface of the fixed rod in the direction away from the reel. The limit ring squeezes the first spring, causing the first spring to be gradually compressed. This process In the process, since the inner wall of the limit ring is an inclined surface, space is gradually left for the limit rod, so the second spring, which is initially in a compressed state, gives an elastic force to the limit rod, so that the two limit rods move away from each other along the fixed rod at the same time. In this process, one end of the limit rod always slides along the inclined inner wall of the limit ring, and the two limit rods slide out of the mounting rod. At this time, the reel is operated to make the reel and the mounting rod slide away from the fixed rod, a reel of a specified diameter is taken, and the mounting rod of the new reel is slid into the inner wall of the fixed rod, the auxiliary rod is released, and the first spring in a compressed state gives an elastic force to the limit ring, so that the limit ring moves along the fixed rod in the direction close to the reel. This process During the process, the inner wall inclined surface of the limit ring squeezes the limit rod, so that the two limit rods move towards each other at the same time until the limit rod slides into the mounting rod, so that the reel is fixed on the mounting column, and then the adjusting rod is rotated in the opposite direction. The adjusting rod drives the limit plate to move towards the direction close to the reel with the help of the thread, and the distance between the limit plate and the reel is adjusted according to the diameter of the steel wire. This realizes the convenient disassembly and assembly between the reel and the mounting column by operating the auxiliary rod. The position of the limit plate can be changed by operating the adjusting rod to match reels of different diameters, which is convenient for users to replace reels of different diameters to produce springs of different inner diameters, saving replacement costs and having high practicality.

[0032] The working principle of a spring processing wire twisting mechanism provided by the utility model is as follows: when the wire twisting mechanism is needed to process the steel wire into a spring, the control interface 2 is first used to program the driving device 3 and the wire feeding device 6, and the equipment is started. The wire feeding device 6 first conveys the steel wire to between the reel 5 and the limit plate 703, and the driving device 3 drives the mounting column 4 and the reel 5 to rotate. During this process, the limit plate 703 on the mounting column 4 cooperates with the reel 5 to curl one end of the steel wire, and the wire feeding device 6 drives the steel wire to move in the extension direction of the reel 5 while conveying the steel wire, and the steel wire is twisted into a spring shape along the arc surface of the reel 5. However, this spring processing twisting mechanism has the following problems: the traditional mounting column 4, the limit plate 703, and the reel 5 are integrated , it is prepared according to the diameter size of the steel wire and the inner diameter size of the spring to be produced. When using steel wires of different diameter sizes to produce springs of different inner diameter sizes, it is necessary to prepare and replace multiple sets of integrated mounting columns 4, limit plates 703 and reels 5, which is cumbersome and costly. By setting the adjustment structure 7, the adjustment rod 702 is first rotated, and the adjustment rod 702 drives the limit plate 703 to move upward along the adjustment groove 701 with the help of the thread. After leaving a suitable distance, the auxiliary rods 710 on both sides are moved away from the reel 5. The auxiliary rods 710 drive the limit ring 708 to move along the arc surface of the fixed rod 707 in the direction away from the reel 5. The limit ring 708 squeezes the first spring 709 to gradually compress the first spring 709. In this process, due to the limit ring The inner wall of 708 is an inclined surface, which gradually leaves space for the limiting rod 715. Therefore, the second spring 716, which is initially in a compressed state, gives an elastic force to the limiting rod 715, so that the two limiting rods 715 move away from each other along the fixing rod 707 at the same time. During this process, one end of the limiting rod 715 always slides along the inclined inner wall of the limiting ring 708, and the two limiting rods 715 slide out of the mounting rod 713. At this time, the reel 5 is operated to make the reel 5 and the mounting rod 713 slide away from the fixing rod 707, and a reel 5 of a specified diameter size is taken out, and the mounting rod 713 of the new reel 5 is slid into the inner wall of the fixing rod 707, and the auxiliary rod 710 is loosened. The first spring 709 in a compressed state gives an elastic force to the limiting ring 708, so that the limiting ring 708 moves along the fixing rod 707. When the adjusting rod 702 is in the fixed position, the stopper 703 is moved in the direction close to the reel 5. During the process, the inner wall inclined surface of the limit ring 708 squeezes the limit rod 715, so that the two limit rods 715 move in the direction close to each other at the same time, until the limit rod 715 slides into the mounting rod 713, so that the reel 5 is fixed on the mounting column 4, and then the adjusting rod 702 is rotated in the opposite direction. The adjusting rod 702 drives the limit plate 703 to move in the direction close to the reel 5 with the help of the thread, and the distance between the limit plate 703 and the reel 5 is adjusted according to the diameter of the steel wire. The limit plate 703 is further limited by the sliding rod 704, so that the limit plate 703 is more stable when moving, and the pulley 705 is used to reduce the friction between the limit plate 703 and the inner wall of the adjusting groove 701, so that the limit plate 703 moves along the inner wall of the adjusting groove 701 more smoothly.The auxiliary rod 710 is driven to move by operating the auxiliary block 711, which is convenient for the user to move the auxiliary rod 710. The friction on the surface of the auxiliary block 711 is increased by the anti-slip pad 712, which is convenient for the user to operate the auxiliary block 711. The positioning bar 714 makes the docking effect between the installation rod 713 and the fixed rod 707 better, which is convenient for the subsequent limiting rod 715 to slide into the installation rod 713. By operating the auxiliary rod 710, the convenient disassembly and assembly between the reel 5 and the installation column 4 can be achieved. The adjustment rod 702 is operated to change the position of the limiting plate 703 to match the reels 5 of different diameters, which is convenient for the user to replace the reels 5 of different diameters to produce springs of different inner diameters, saving replacement costs and high practicality.
