AI Technical Summary
Existing CNC lightweight flying shear straightening machines use a motor and pulley structure to drive the cutter, resulting in low transmission efficiency, slow cutter movement speed, and insufficient shearing force. They can only cut steel wires with a diameter of 1.5-3mm, and have poor adaptability.
The shearing motor directly drives the cam to rotate, which in turn drives the lower pressure block to slide, triggering the shearing telescopic rod to extend and retract, which in turn drives the cutter to move quickly. The spacing between the guide wheels can be adjusted by combining the guide wheel and the adjusting threaded rod to accommodate steel wires of different diameters.
It improves the transmission efficiency and movement speed of the cutter, enhances the shearing force, expands the range of wire diameters that the equipment can adapt to, and improves the adaptability and application range of the equipment.

[0021] 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.
[0022] Please see Figs. 1 to 4 This embodiment of a CNC lightweight flying shear straightening machine includes a machine body 1. A first mounting frame 2, a second mounting frame 3, a straightening machine 4, and a shearing frame 5 are fixedly mounted on the machine body 1. The shearing frame 5 is provided with a cam shearing mechanism, which includes a shearing motor 6 and a sliding bracket 7 fixedly mounted on the surface of the shearing frame 5. The output end of the shearing motor 6 passes through the shearing frame 5 and is fixedly mounted with a cam 8. A lower pressure block 9 is slidably mounted on the surface of the sliding bracket 7. A shearing table 10 located directly below the lower pressure block 9 is fixedly mounted on the surface of the sliding bracket 7. A shearing telescopic rod 11 is fixedly mounted on the surface of the shearing table 10. A cutter 12 is fixedly mounted at the bottom of the shearing telescopic rod 11. The lower pressure block 9 and the cam 8 are slidably connected.
[0023] The straightening machine 4 is located between the first mounting frame 2 and the second mounting frame 3. The second mounting frame 3 is close to the shearing frame 5. A limiting block 21 located directly above the lower pressure block 9 is fixedly installed on the surface of the sliding bracket 7.
[0024] The first mounting bracket 2 is provided with three first guide wheels 13 and three second guide wheels 14. The first guide wheels 13 are located directly above the second guide wheels 14. The surface of the first mounting bracket 2 is threaded with a first adjusting threaded rod 15. A first connecting block 16 is slidably installed on the inner side of the first mounting bracket 2. The first guide wheels 13 are rotatably installed on the first connecting block 16. The first adjusting threaded rod 15 is rotatably connected to the first connecting block 16, which facilitates the adjustment of the distance between the first guide wheels 13 and the second guide wheels 14.
[0025] The second mounting bracket 3 is provided with two third guide wheels 17 and two fourth guide wheels 18. The third guide wheel 17 is located directly above the fourth guide wheel 18. The surface of the second mounting bracket 3 is threaded with a second adjusting threaded rod 19. The second connecting block 20 is slidably installed on the inner side of the second mounting bracket 3. The third guide wheel 17 is rotatably installed on the second connecting block 20. The second adjusting threaded rod 19 is rotatably connected to the second connecting block 20, which facilitates the adjustment of the distance between the third guide wheel 17 and the fourth guide wheel 18.
[0026] It should be noted that two horizontal plates 22 are fixedly installed on the surface of the first mounting bracket 2, and two vertical plates 23 are fixedly installed on the horizontal plates 22 away from the surface of the first mounting bracket 2. Two first guide limit wheels 24 rotate between the two horizontal plates 22 on opposite sides, and two second guide limit wheels 25 rotate between the two vertical plates 23 on opposite sides.
[0027] It should be noted that when the steel wire is fed into the straightening machine 4 and passes through the first guide wheel 13, the second guide wheel 14, the third guide wheel 17 and the fourth guide wheel 18, the tension of the steel wire will drive the first guide wheel 13, the second guide wheel 14, the third guide wheel 17 and the fourth guide wheel 18 to rotate, so that the first guide wheel 13, the second guide wheel 14, the third guide wheel 17 and the fourth guide wheel 18 can rotate automatically as the steel wire moves.
[0028] The working principle of the above embodiments is as follows:
[0029] The first guide limit wheel 24 and the second guide limit wheel 25 on the horizontal plate 22 and the vertical plate 23 can guide and limit the steel wire, ensuring that the steel wire can pass sequentially through the first guide wheel 13, the second guide wheel 14, the third guide wheel 17 and the fourth guide wheel 18 on the first mounting frame 2 and the second mounting frame 3, so that the steel wire passes through the straightening machine 4 and the shearing frame 5. The straightening machine 4 is located between the first mounting frame 2 and the second mounting frame 3. Through internal straightening rollers or straightening mechanisms, it can straighten the bent steel wire into a straight shape for subsequent shearing. When the shearing motor 6 starts, its output end drives the cam 8 to rotate. The rotational motion of wheel 8 is transmitted to the lower pressure block 9 through a sliding connection, causing the lower pressure block 9 to slide up and down on the sliding bracket 7. The downward movement of the lower pressure block 9 triggers the shearing telescopic rod 11 on the shearing table 10 to extend and retract, thereby driving the cutter 12 to move up and down to shear the steel wire. The limiting block 21 on the surface of the sliding bracket 7 is used to limit the sliding range of the lower pressure block 9 to ensure the stability of the shearing process. By rotating the first adjusting threaded rod 15 and the second adjusting threaded rod 19, the positions of the first connecting block 16 and the second connecting block 20 can be adjusted respectively, thereby changing the position of the guide wheel to adapt to steel wires of different diameters.
