A winding device for a computer-controlled spring coiling machine

Abstract

This utility model discloses a winding device for a computer-controlled spring coiling machine, relating to the field of spring coiling machine technology. The winding device includes a spring coiling machine with four turntables rotatably mounted on its surface. Steel wires are slidably connected inside the four turntables. A circular disc is rotatably connected to the surface of the spring coiling machine, and the steel wire contacts the surface of the circular disc. A trapezoidal groove is formed on the surface of the spring coiling machine, and a trapezoidal block is slidably connected inside the trapezoidal groove. A limit device is provided on the surface of the trapezoidal block. In this winding device, as the wire gradually moves to the right inside the limit block, the friction between the wire and the wear-resistant ball causes the wear-resistant ball to roll inside the annular groove, thereby reducing the friction between the wire and the limit block and reducing the wear on the inner wall of the limit block. This not only increases the service life of the limit block but also reduces the resistance during the wire's movement, resulting in less power required for the wire to move.

Description

Technical Field

[0001] This utility model relates to the field of spring coiling machine technology, and in particular to a winding device for a computer spring coiling machine. Background Technology

[0002] Spring coiling machines, also known as spring machines, generally refer to mechanical equipment used to produce springs. Based on their functional characteristics, they are categorized as: compression spring machines, tension spring machines, universal machines, disc spring machines, and specialized spring machines such as serpentine spring machines and torsion spring machines. Springs are commonly used components in industry, used in everything from large items like airplanes and warships to small items like mobile phones and cameras. Therefore, spring production has a history of several hundred years. The earliest springs were simply cylindrical tension and compression springs, hand-wound, with relatively immature technology and low production efficiency. As the demand for springs gradually increased, the technology related to spring machines also matured.

[0003] In the current fully automatic computer-controlled spring coiling machine, during the process of coiling steel wire into a spring, workers need to install limit blocks to ensure stable pressing between the steel wire and the coiling rollers. The limit blocks limit the steel wire. Because the limit blocks and steel wire are in sliding contact, the wear between the steel wire and the inner wall of the limit blocks is quite severe. Severely worn limit blocks need to be replaced, which not only reduces the service life of the limit blocks, but also makes the replacement operation troublesome and costly. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a winding device for a computer spring coiling machine, which can solve the problem that the wear between the steel wire and the inner wall of the limit block is relatively serious due to the sliding contact between the limit block and the steel wire, and the limit block with severe wear needs to be replaced.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a winding device for a computer-controlled spring coiling machine, comprising a spring coiling machine, wherein four turntables are rotatably arranged on the surface of the spring coiling machine, and steel wires are slidably connected inside the four turntables; a disc is rotatably connected to the surface of the spring coiling machine, and the steel wires are in contact with the surface of the disc. The spring coiling machine has a trapezoidal groove on its surface, a trapezoidal block is slidably connected inside the trapezoidal groove, and a limit device is provided on the surface of the trapezoidal block.

[0006] Preferably, the limiting device includes a limiting block, which is fixedly connected to the surface of the trapezoidal block, and the limiting block is slidably sleeved on the surface of the steel wire. An annular groove is provided inside the limiting block. The annular groove has wear-resistant balls that slide inside it. The wear-resistant balls are evenly distributed inside the annular groove, and the surface of the wear-resistant balls is in contact with the surface of the steel wire.

[0007] Preferably, a pull rod is slidably sleeved inside the trapezoidal block, and a pull ring is fixedly connected to the surface of the pull rod.

[0008] Preferably, the inner wall of the trapezoidal groove is provided with a fixing hole, and the end of the pull rod away from the pull ring is slidably engaged inside the fixing hole.

[0009] Preferably, the trapezoidal block has a circular groove inside, and a circular ring is slidably connected inside the circular groove, with the circular ring fixedly sleeved on the surface of the pull rod.

[0010] Preferably, a fixing spring is slidably sleeved on the surface of the pull rod, the fixing spring is fixedly connected to the surface of the ring, and the end of the fixing spring away from the ring is fixedly connected to the inner wall of the circular groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) In the winding device of the computer spring coiling machine, as the wire gradually moves to the right inside the limiting block, the steel wire drives the wear-resistant ball to roll inside the annular groove through the friction between the steel wire and the wear-resistant ball, thereby reducing the friction between the steel wire and the limiting block and reducing the wear of the inner wall of the limiting block. This not only improves the service life of the limiting block, but also reduces the resistance during the movement of the steel wire, making the power required for the movement of the steel wire smaller, thereby reducing the power consumption of the winding device and saving power resources.

[0012] (2) The winding device of the computer spring coiling machine moves the pull rod and slides out of the inside of the fixed card hole, thereby releasing the fixing effect of the fixed card hole on the trapezoidal block. Then, the operator can slide the limit block upward. The limit block slides upward and drives the trapezoidal block to slide out of the inside of the trapezoidal groove to complete the disassembly. This makes it convenient for the operator to disassemble and install the limit block, and improves the ease of use of the winding device. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0018] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a winding device for a computer spring coiling machine, including a spring coiling machine 1, four turntables 2 are rotatably arranged on the surface of the spring coiling machine 1, steel wires 3 are slidably connected inside the four turntables 2, and a disc 4 is rotatably connected to the surface of the spring coiling machine 1, with the steel wires 3 in contact with the surface of the disc 4. Among them, the surface of the spring coiling machine 1 is provided with a trapezoidal groove 5, the inside of the trapezoidal groove 5 is slidably connected to a trapezoidal block 6, the surface of the trapezoidal block 6 is fixedly connected to a limit block 7, and the limit block 7 is slidably sleeved on the surface of the steel wire 3. After the staff put the steel wire into the four turntables 2, the four turntables 2 rotated at the same time and the steel wire was moved to the right by the friction between them. The steel wire moved to the right, passed through the limit block 7 and came into contact with the surface of the disc 4. The disc 4 rotated and caused the steel wire to bend and deform into the shape of a spring.

[0020] The limiting block 7 has an annular groove 8 inside, and wear-resistant balls 9 are slidably connected inside the annular groove 8. The wear-resistant balls 9 are evenly distributed inside the annular groove 8, and the surface of the wear-resistant balls 9 is in contact with the surface of the steel wire 3.

[0021] As the steel wire 3 gradually moves to the right inside the limiting block 7, the friction between the steel wire 3 and the wear-resistant ball 9 causes the wear-resistant ball 9 to roll inside the annular groove 8, thereby reducing the friction between the steel wire 3 and the limiting block 7 and reducing the wear on the inner wall of the limiting block 7. This not only improves the service life of the limiting block 7, but also reduces the resistance during the movement of the steel wire 3, making the power required for the movement of the steel wire 3 less, thereby reducing the power consumption of the winding device and saving power resources.

[0022] Among them, a pull rod 10 is slidably sleeved inside the trapezoidal block 6, and a pull ring 11 is fixedly connected to the surface of the pull rod 10. A fixing hole 15 is opened on the inner wall of the trapezoidal groove 5, and the end of the pull rod 10 away from the pull ring 11 is slidably locked inside the fixing hole 15. Among them, the trapezoidal block 6 has a circular slot 12 inside, and a circular ring 13 is slidably connected inside the circular slot 12. The circular ring 13 is fixedly sleeved on the surface of the pull rod 10. Among them, a fixed spring 14 is slidably sleeved on the surface of the pull rod 10. The fixed spring 14 is fixedly connected to the surface of the ring 13, and the end of the fixed spring 14 away from the ring 13 is fixedly connected to the inner wall of the circular groove 12.

[0023] When the limiting block 7 needs to be replaced after prolonged use, the operator pulls the pull ring 11. The movement of the pull ring 11 moves the pull rod 10, which in turn moves the ring 13, causing it to slide and compress the fixing spring 14. The fixing spring 14 applies a counterforce to the ring 13, causing the pull rod 10 to move and slide out of the fixing hole 15. This releases the fixing effect of the fixing hole 15 on the trapezoidal block 6. Then, the operator can slide the limiting block 7 upwards. The upward sliding of the limiting block 7 causes the trapezoidal block 6 to slide upwards out of the trapezoidal groove 5, thus completing the disassembly. This facilitates the disassembly and installation of the limiting block 7, improving the ease of use of the winding device.

[0024] Working principle: In this computer-controlled spring coiling machine, the operator places the steel wire into the four turntables 2. The four turntables 2 rotate simultaneously, moving the steel wire to the right. The wire passes through the limiting block 7 and contacts the surface of the disc 4. As the wire 3 gradually moves to the right inside the limiting block 7, the friction between the wire 3 and the wear-resistant balls 9 causes the balls 9 to roll within the annular groove 8, thereby reducing the friction between the wire 3 and the limiting block 7 and minimizing wear on the inner wall of the limiting block 7. When the limiting block 7 needs to be replaced after prolonged use... When the operator pulls the pull ring 11, the pull ring 11 moves, which in turn moves the pull rod 10. The movement of the pull rod 10 causes the ring 13 to slide and compress the fixing spring 14. The fixing spring 14 exerts a counterforce on the ring 13, causing the pull rod 10 to move and slide out of the fixing hole 15, thereby releasing the fixing effect of the fixing hole 15 on the trapezoidal block 6. Then, the operator can slide the limiting block 7 upward. The upward sliding of the limiting block 7 causes the trapezoidal block 6 to slide upward out of the trapezoidal groove 5, thus completing the disassembly. This makes it convenient for the operator to disassemble and install the limiting block 7, improving the ease of use of the winding device.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
