Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic bending machines, specifically a multi-angle rapid adjustment device for hydraulic bending machines. Background Technology
[0002] The multi-angle rapid adjustment device for hydraulic bending machines is a functional component specially designed for bending machines. Its main function is to quickly adjust the included angle of the workpiece being lifted to be bent, so as to achieve precise bending of the workpiece at different angles. It can quickly change the included angle between the workpiece and the bending machine to meet the needs of multi-angle bending of workpieces in production. It is an auxiliary tool that can improve bending efficiency and accuracy, enabling hydraulic bending machines to complete various complex bending tasks more flexibly and efficiently.
[0003] Chinese patent CN220611808U discloses an adjustable hydraulic bending machine, including a template. Both ends of the template are rotatably connected to fixed blocks via rotating shafts. The bottom of the fixed blocks is fixedly connected to the upper surface of the base plate. When the height of the inner plate is adjusted, the included angle between the two templates can be flexibly adjusted, thereby facilitating the production of components with different bending angles according to requirements, improving work efficiency, and making operation simple and convenient.
[0004] When adjusting and supporting the template, the aforementioned patented adjustable hydraulic bending machine requires simultaneous adjustment of the templates on both sides. The adjustment speed is slow and the process is inconvenient. When the templates on both sides are adjusted sequentially, resulting in different tilt angles on both sides, the bending effect will be reduced, and bending failure is likely to occur. Utility Model Content
[0005] The purpose of this utility model is to provide a multi-angle rapid adjustment device for a hydraulic bending machine. After the transmission block is extended, the transmission block can be pushed by the support wheel to make the template at the upper end rotate around the connecting shaft in a pair of first supports. The support wheels at the four corners of the upper end of the transmission block can simultaneously adjust the angle of the two templates. After the angle is adjusted, the extension distance is maintained by the rotation of the fixing block and the hydraulic rod, which can support and fix the template. At the same time, the angle of the template can be adjusted and fixed, thus avoiding the problem mentioned in the background art when the tilt angles of the templates on both sides are different.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle rapid adjustment device for a hydraulic bending machine, comprising two symmetrically distributed templates. Each template has a first support rotatably connected to its sides via a connecting shaft. A transmission block is laterally arranged at the lower end of each template. Support wheels are welded and fixed to the four corners of the upper end of each transmission block via connecting rods. Second supports with first sliding rails are arranged on both sides of the lower outer end of each transmission block, and the transmission block is embedded within and slidably connected to the interior of the first sliding rail. A hydraulic rod is vertically arranged at the lower end of the interior of the first sliding rail. Pushing the hydraulic rod causes its extension and retraction to drive the transmission block to slide horizontally along the first sliding rail. The first sliding rail provides the transmission block with a stable movement trajectory, ensuring the stability of the entire adjustment device when adjusting the template's tilt angle, preventing tilting and bending.
[0007] Preferably, one end of the hydraulic rod is fixedly connected to the transmission block by bolts, and the outside of the hydraulic rod is fixedly connected to the second bracket by bolts. The bolts fix the hydraulic rod inside the first sliding rail, and the hydraulic rod can stably push the transmission block to adjust its horizontal position.
[0008] Preferably, a reinforcing plate is provided between the middle position of the lower end of the transmission block and the position where the lower end of the transmission block is embedded in the first sliding rail. The reinforcing plate is triangular and can reinforce the transmission block to prevent it from bending and breaking under pressure.
[0009] Preferably, each of the two templates has an extension piece on one side, and a threaded rod is provided on one side of the extension piece. During the process of adjusting the angle of the template, the threaded rod will be driven to adjust its position synchronously. The threaded rod will move along the second sliding rail. The stability of the template position adjustment process can be improved by restricting the threaded rod by the second sliding rail.
[0010] Preferably, a bending head is provided at the upper end between the two templates, and a shell is provided on the outside of the bending head. A second sliding rail is provided on the shell corresponding to the position of the threaded rod. The threaded rod, the extension piece and the template are welded and fixed in sequence. The shell is fixedly connected to the first bracket and the second bracket by bolts. The bolt fixing can support and connect the second bracket and the first bracket, so that the template connected to the first bracket and the transmission block connected to the second bracket can be stably suspended inside the shell.
[0011] Preferably, a fixing block is provided on one side of the second sliding rail, and the inside of the fixing block is threaded with the outside of the threaded rod. After the fixing block is continuously rotated, it will move toward the outer shell. After moving and fitting the outer shell, the threaded rod with the adjusted angle can be fixed. At the same time as the threaded rod is fixed, the template corresponding to the threaded rod will also be fixed. The fixing block fits with the outer shell to assist the hydraulic rod in supporting and fixing the angle of the template.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] When adjusting the tilt angle of the template, this invention allows the template to rotate between a pair of first supports around the connecting shaft by adjusting the height of the transmission block horizontally and connecting the connecting rod and the support wheel. The upper end of the transmission block is independently equipped with support wheels facing the two templates. By adjusting the horizontal position of the transmission block individually, the tilt angle of the template can be adjusted simultaneously. On the other hand, when the template rotates and the tilt direction is adjusted, the extension piece and threaded rod connected to the template will slide in the second sliding rail. After the hydraulic rod is driven to adjust the angle, the fixed block rotates outside the threaded rod while the hydraulic rod provides continuous support until the fixed block fits against the outer shell. By fixing the fixed block against the outer shell in conjunction with the extension distance of the hydraulic rod, the template can be fixed at the corresponding angle, and the tilt state of the template can withstand the pressure generated by the downward pressure of the upper bending head.

[0022] The present invention will be further described below with reference to specific embodiments.
[0023] like Figure 1 As shown, the hydraulic bending machine multi-angle rapid adjustment device of this embodiment includes two symmetrically distributed templates 3. Each template 3 has a first support 5 on both sides. The first support 5 is rotatably connected to the two sides of the two templates 3 through a connecting shaft 8. The templates 3 and the two first supports 5 can be rotated around the connecting shaft 8 to adjust the angle. The two templates 3 can rotate simultaneously to cope with the downward pressure of the upper bending head 2, and can bend the material to be bent placed between the bending head 2 and the template 3.
[0024] In order to support the template 3 and the first support 5, a bending head 2 is provided at the upper end between the two templates 3. The bending head 2 is provided with a shell 1, and the shell 1 is fixedly connected to the first support 5 by bolts. The first support 5 can support the template 3 by fixing it with bolts.
[0025] Among them, such as Figure 2 and Figure 3 As shown, after the template 3 is angled, a transmission block 11 is horizontally arranged at the lower end of the two templates 3. A support wheel 4 is arranged at each of the four corners of the upper end of the transmission block 11. The outer wall of the support wheel 4 is welded and fixed to the transmission block 11 by a connecting rod 9. During the horizontal adjustment of the transmission block 11, the transmission block 11 will drive the support wheel 4 through the connecting rod 9. During the horizontal adjustment, the support wheel 4 will contact and lift the template 3. When the template 3 is lifted and contacted, it will rotate around the connecting shaft 8 as the center and adjust the angle.
[0026] It is worth mentioning that second brackets 6 are provided on both sides of the lower outer end of the transmission block 11, such as... Figure 4 and Figure 5 As shown, the second bracket 6 has a first sliding rail 12 vertically arranged inside, and the transmission block 11 is embedded inside the first sliding rail 12 and slidably connected to the inside of the first sliding rail 12. During the horizontal position adjustment, the transmission block 11 slides inside the first sliding rail 12. The restriction and guidance of the first sliding rail 12 can improve the stability of the horizontal position movement of the transmission block 11 and improve the stability of the template 3 after the horizontal position is adjusted.
[0027] In order to actively adjust the horizontal position of the transmission block 11, a hydraulic rod 7 is vertically installed at the lower end of the first sliding rail 12. One end of the hydraulic rod 7 is fixedly connected to the transmission block 11 by bolts, and the outside of the hydraulic rod 7 is fixedly connected to the second bracket 6 by bolts. The horizontal position of the transmission block 11 can be adjusted by the extension and retraction of the hydraulic rod 7, and the tilt angle of the template 3 can be actively adjusted. After the hydraulic rod 7 is fixed at the extension distance, the template 3 after the angle adjustment can be fixed by the hydraulic rod 7, thus fixing the tilt angle of the template 3.
[0028] In addition, in order to connect and fix the second bracket 6, the second bracket 6 is fixedly connected to the outer shell 1 by bolts. The connection of the second bracket 6 makes it easy to adjust the horizontal position of the transmission block 11.
[0029] To improve the support capacity of the transmission block 11, a reinforcing plate 13 is provided between the middle position of the lower end of the transmission block 11 and the position where the lower end of the transmission block 11 is embedded in the first sliding rail 12. The reinforcing plate 13 is triangular. The triangular reinforcing plate 13 can reinforce and support the transmission block 11, preventing the transmission block 11 from bending during the process of pushing the template 3, and also preventing the bending of the transmission block 11 from bending when bending the material due to the pressing force generated by the bending head 2.
[0030] Furthermore, each of the two templates 3 has an extension piece 10 on one side, and a threaded rod 15 is provided on one side of the extension piece 10, such as... Figure 6 and Figure 7 As shown, the outer shell 1 is provided with a second sliding rail 14 at the position corresponding to the threaded rod 15. The threaded rod 15, the extension piece 10 and the template 3 are welded and fixed in sequence. The template 3 drives the threaded rod 15 to move within the second sliding rail 14 through the extension piece 10. A fixing block 16 is provided on one side of the outer side of the second sliding rail 14, and the inside of the fixing block 16 is threaded with the outside of the threaded rod 15. When the fixing block 16 rotates outside the threaded rod 15, it can move towards the outer shell 1. With the continuous rotation of the fixing block 16, the fixing block 16 can fit against the outer shell 1, fixing the position of the threaded rod 15 within the second sliding rail 14. By fixing the position of the threaded rod 15, the template 3 after angle adjustment is fixed at the same time.
[0031] Working principle: When using the device and adjusting the angle of template 3, the hydraulic rod 7 vertically installed inside the second bracket 6 is activated. The extension of the hydraulic rod 7 pushes the transmission block 11 to adjust its horizontal position within the first sliding rail 12. The transmission block 11 can push the support wheel 4 to squeeze the template 3 through the connecting rod 9. After the template 3 is squeezed, the lower end of the template 3 rotates around the connecting shaft 8 within the first brackets on both sides. The rotation can adjust the tilt angle of the template 3. During the tilting process of the template 3, the extension piece 10 will drive the threaded rod 15 to move within the second sliding rail 14. After the threaded rod 15 is adjusted with the angle of the template 3, the fixing block 16 is rotated outside the threaded rod 15. The fixing block 16 is rotated and makes the fixing block 16 fit against the surface of the outer shell 1. The fixing block 16 fits against the outer wall of the outer shell 1 and, together with the hydraulic rod 7, maintains the extension distance while supporting the template 3.
