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.

Therefore, they should not be construed as limitations on this utility model.
[0025] Please see Figures 1-3 The above describes a high-stability cold bending machine upright frame, which includes an upright plate 1, two symmetrically arranged linear guide pairs 2, a roller assembly 3, a first lead screw drive pair 4, a second lead screw drive pair 5, and a locking plate 6.
[0026] Linear guide rail pair 2 is mounted on the upright plate 1 of the upright rod, and roller assembly 3 is connected to the slider on the linear guide rail pair 2. The linear guide rail pair 2 provides precise linear motion guidance for roller assembly 3, enabling roller assembly 3 to move smoothly along a specific trajectory on the upright plate 1, ensuring the accuracy and smoothness of the upright rod frame when adjusting the spacing between the upright rods.
[0027] A handle wheel 9 is mounted on the lead screw of both the first lead screw drive pair 4 and the second lead screw drive pair 5. A roller assembly 3 near the handle wheel 9 is connected to the lead screw nut on the first lead screw drive pair 4, while the roller assembly 3 away from the handle wheel 9 is connected to the lead screw nut on the second lead screw drive pair 5. By rotating the handle wheel 9, the operator can rotate the corresponding lead screw, causing the lead screw nut to move linearly along the lead screw, thereby adjusting the position of the corresponding roller assembly 3 and changing the distance between the vertical rollers.
[0028] The upright plate 1 has T-shaped grooves 7 on both sides, and T-bolts 8 are installed in the T-shaped grooves 7. Each roller assembly 3 has a locking plate 6 on both sides. The upper part of the locking plate 6 is connected to the roller assembly 3, and the lower part of each locking plate 6 is connected to the upright plate 1 by the T-bolts 8. After the upright spacing is adjusted to the appropriate position, tightening the nuts and T-bolts 8 can firmly fix the roller assembly 3 to the upright plate 1 by the locking plates 6, effectively preventing the roller assembly 3 from shifting due to vibration, thereby ensuring the stability of the gap between the uprights.
[0029] Furthermore, the roller assembly 3 includes a roller box 301, a rotating shaft 302, and a pressure roller 303. The lower part of the roller box 301 is fixedly connected to the slider on the linear guide pair 2. The lower end of the rotating shaft 302 is connected to the roller box 301 through a bearing, and the other end is connected to the upper end face of the roller box 301 through a bearing. The end of the rotating shaft 302 away from the linear guide pair 2 extends to the outside of the roller box 301 and is connected to the pressure roller 303.
[0030] Furthermore, the lead screw nut on the first lead screw drive pair 4 is fixedly connected to the inner wall of the roller box 301 on the roller assembly 3 near the handle wheel 9. In this way, when the handle wheel 9 is rotated to drive the lead screw of the first lead screw drive pair 4 to rotate, the lead screw nut can accurately drive the corresponding roller assembly 3 to move along the linear guide pair 2.
[0031] Furthermore, the lead screw nut on the second lead screw drive pair 5 is fixedly connected to the inner wall of the roller box 301 on the roller assembly 3 at the end away from the handle wheel 9. Similarly, this ensures that the roller assembly 3 at the end away from the handle wheel 9 can move precisely as the lead screw of the second lead screw drive pair 5 rotates, thereby achieving effective adjustment of the spacing between the upright rollers.
[0032] Furthermore, the locking plate 6 has a Z-shaped structure. This special structural design allows the locking plate 6 to better distribute pressure when connecting the roller assembly 3 and the upright plate 1, providing a more stable connection and enhancing the stability of the entire upright frame.
[0033] Furthermore, the upright plate 1 is connected to the body of the cold bending machine. This reliable connection provides a stable support foundation for the upright frame, ensuring its overall stability during operation.
[0034] Working principle:
[0035] When the spacing between the vertical rollers needs to be adjusted according to different workpiece specifications, the operator does so by rotating the handle wheel 9 on the first lead screw drive pair 4 and the second lead screw drive pair 5. Taking the first lead screw drive pair 4 as an example, when the handle wheel 9 is rotated, it drives the lead screw to make a circular motion. Since the lead screw nut and the lead screw are connected by a threaded fit, the circular motion of the lead screw is converted into the linear motion of the lead screw nut. The lead screw nut on the first lead screw drive pair 4 is fixedly connected to the inner wall of the roller box 301 on the roller assembly 3 near the handle wheel 9, so the linear motion of the lead screw nut will drive the roller assembly 3 to move linearly along the slider on the linear guide pair 2.
[0036] Similarly, when the handle wheel 9 on the second lead screw drive pair 5 is rotated, the roller assembly 3 at the end away from the handle wheel 9 will move along the linear guide pair 2. By controlling the rotation direction and number of rotations of the two handle wheels 9 respectively, the distance between the two roller assemblies 3 can be precisely adjusted, thereby achieving flexible adjustment of the vertical roller spacing to adapt to the processing requirements of workpieces of different thicknesses and sizes.
[0037] The linear guide pair 2 plays a crucial role in this process. It provides precise guidance for the movement of the roller assembly 3, ensuring that the roller assembly 3 can only move along a specific straight trajectory, avoiding deviation and wobbling during adjustment, and guaranteeing the accuracy and stability of the vertical roller spacing adjustment.
[0038] After adjusting the spacing between the uprights to the appropriate position, in order to prevent the vibration generated during the operation of the cold bending machine from changing the gap between the uprights, it is necessary to lock the roller assembly 3. Specifically, this is done by tightening the T-bolts 8 in the T-grooves 7 on both sides of the upright plate 1.
[0039] Each roller assembly 3 has a Z-shaped locking plate 6 on both sides. The upper part of the locking plate 6 is connected to the roller assembly 3, and the lower part is connected to the upright plate 1 via T-bolts 8. When the T-bolts 8 are tightened, they generate a downward pulling force, causing the locking plate 6 to press tightly against the upright plate 1. At the same time, since the locking plate 6 is connected to the roller assembly 3, it securely fixes the roller assembly 3 to the upright plate 1.
[0040] The Z-shaped locking plate 6, when subjected to the tension of the T-bolt 8, can better disperse pressure and avoid localized stress concentration. On the one hand, it can more effectively transmit the pressure of the roller assembly 3 to the upright plate 1, enhancing the stability of the connection; on the other hand, it also reduces the possibility of damage to the upright plate 1 and roller assembly 3 due to excessive pressure. Through this locking method, even if the cold bending machine generates strong vibrations during operation, the roller assembly 3 will not shift, thereby ensuring the stability of the gap between the uprights and improving the processing accuracy and quality of the workpiece.
[0041] This invention is not limited to the details of the exemplary embodiments described above, and can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
