Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 and Figure 2This utility model provides a technical solution: a hot-rolling spring machine for spring production, including a workbench 1 and a hot-rolling shaft 8. Two symmetrically arranged first fixed plates 2 are fixedly connected to the top surface of the workbench 1. A roller 3 is rotatably connected between the two first fixed plates 2. A drive motor 4 is arranged on one side of the workbench 1. The drive shaft of the drive motor 4 passes through one of the first fixed plates 2 and is fixedly connected to the roller 3. A guide assembly is arranged on the roller 3. The end of the roller 3 away from the drive motor 4 passes through the first fixed plate 2 and is fixedly connected to a large pulley 5. The large pulley 5 is connected to a small pulley 6 through a belt drive. A second fixed plate 7 is fixedly connected to the top surface of the workbench 1. The small pulley 6 is rotatably installed on the outer side wall of the second fixed plate 7. A detachable assembly is arranged through the second fixed plate 7. The detachable assembly is used to form a detachable assembly of the hot-rolling shaft 8. A telescopic motor 9 is arranged at one end of the detachable assembly. A support assembly is arranged at one end of the top of the workbench 1.

[0024] The easy-to-disassemble component includes an assembly frame 10, in which a push rod 11 is slidably disposed. A telescopic motor 9 is fixedly installed at one end of the push rod 11, and a connecting rod 12 is fixedly connected to the other end of the push rod 11. Both ends of the connecting rod 12 are rotatably connected to a linkage rod 13. A first sliding groove 14 is formed on the outer arc wall of the linkage rod 13. The first sliding groove 14 is bent. A first guide rod 15 is fixedly connected to the inner wall of the assembly frame 10 at the corresponding position of the first sliding groove 14. A limit block 16 is fixedly connected to the end of the linkage rod 13 away from the connecting rod 12. An installation block 17 is fixedly connected to the end of the hot roller 8 near the assembly frame 10. A slot is formed on the outer wall of the installation block 17, and the slot engages with the limit block 16.

[0025] In practice, firstly, one end of the corresponding model of hot roll 8 is placed in the assembly frame 10. Then, the telescopic motor 9 is started to drive the push rod 11 connected to it to move within the assembly frame 10, thereby driving the connecting rod 12 to move. With the first guide slide rod 15 fixedly installed on the inner wall of the assembly frame 10, it can slide in the first slide groove 14 through the first guide slide rod 15, causing the two linkage rods 13 to rotate. Then, the limiting block 16 is engaged with the limiting block 16 opened on the mounting block 17, so that the hot roll 8 is fixed. Then, the heated metal raw material is connected to the hot roll 8, and the drive motor 4 is started to drive the roller 3 to rotate. With the belt drive of the large pulley 5 and the small pulley 6, the large pulley 5 can drive the small pulley 6 to rotate, thereby driving the hot roll 8 to rotate, thus hot-rolling the metal raw material.

[0026] See Figure 3The guiding assembly includes a movable frame 19, a second guide slide rod 20 fixedly connected to the inner top wall of the movable frame 19, a second slide groove 18 opened on the roller 3, the second guide slide rod 20 slidingly engaging with the second slide groove 18, a guide rail 21 fixedly installed on the top surface of the worktable 1, a support rod 22 fixedly connected to the bottom of the movable frame 19, a slider 23 fixedly connected to the bottom of the support rod 22, the slider 23 slidingly installed in the guide rail 21, two symmetrically arranged guide rods 24 fixedly connected to the top of the movable frame 19, the slider 23 slidingly connected to the inner wall of the guide rail 21, the second slide groove 18 being spiral-shaped, and the second slide groove 18 being intersectingly opened on the outer arc wall of the roller 3.

[0027] The rotation of the roller 3, through the sliding cooperation of the second guide slide rod 20 and the second slide groove 18, can drive the moving frame 19 to move back and forth along the setting direction of the roller 3, so that the metal raw material passes between the two guide rods 24, which plays a guiding role and adjusts the contact position between the hot coil shaft 8 and the metal raw material, thereby completing the hot coiling process of the spring.

[0028] See Figure 4 The support assembly includes a bearing plate 25. Two bearing plates 25 are symmetrically fixedly installed on the top surface of the workbench 1. Limiting rods 26 are slidably connected to the top of each of the two bearing plates 25. An arc plate 27 is fixedly connected to the top of the two limiting rods 26. A hydraulic cylinder 28 is fixedly connected to the top surface of the workbench 1, and the output end of the hydraulic cylinder 28 is fixedly connected to the arc plate 27.

[0029] The hydraulic cylinder 28 is activated to push the arc plate 27 to move under the limit of the limit rod 26 until the arc plate 27 contacts the hot roll shaft 8. During the rotation of the hot roll shaft 8, the arc plate 27 can be used to provide auxiliary support for the hot roll shaft 8 and prevent the hot roll shaft 8 from shaking.

[0030] See Figure 4 The top of the arc plate 27 has multiple grooves arranged in a rectangular shape, and each groove is equipped with alloy balls. The alloy balls make the arc plate 27 smoother when it comes into contact with the hot roller 8.

[0031] Working principle:

[0032] First, place one end of the corresponding model of hot roll 8 into the assembly frame 10. Then, start the telescopic motor 9 to drive the push rod 11 connected to it to move within the assembly frame 10, thereby driving the connecting rod 12 to move. In conjunction with the first guide slide rod 15 fixedly installed on the inner wall of the assembly frame 10, the first guide slide rod 15 can slide within the first slide groove 14, causing the two linkage rods 13 to rotate, thereby engaging the limiting block 16 into the limiting block 16 opened on the mounting block 17, thus fixing the hot roll 8.

[0033] Simultaneously, the hydraulic cylinder 28 is activated to push the arc plate 27 to move under the limit of the limit rod 26 until the arc plate 27 contacts the hot coil shaft 8. Then, the heated metal material is connected to the hot coil shaft 8, and the drive motor 4 is activated to drive the roller 3 to rotate. With the belt drive of the large pulley 5 and the small pulley 6, the large pulley 5 drives the small pulley 6 to rotate, which in turn drives the hot coil shaft 8 to rotate, thereby hot-coiling the metal material. During the rotation of the hot coil shaft 8, the arc plate 27 can be used to provide auxiliary support for the hot coil shaft 8 to prevent the hot coil shaft 8 from shaking. The rotation of the roller 3, through the sliding cooperation of the second guide slide rod 20 and the second slide groove 18, can drive the moving frame 19 to move back and forth along the setting direction of the roller 3, so that the metal material passes between the two guide rods 24, which plays a guiding role and adjusts the contact position between the hot coil shaft 8 and the metal material, thereby completing the hot coiling process of the spring.
