Description

[0002] Cold bending machine, also known as arch bending machine, is mainly used for bending I-beams, channel steels, angle steels, U-beams and other profiles in tunnels, subways, hydropower stations, underground caverns, etc. It consists of six major parts: base, mechanical transmission, cold bending system, hydraulic system, electrical control system and auxiliary system.

[0003] In the process of processing seismic brackets, in order to process seismic brackets with different curvatures, a corresponding cold bending machine with adjustable curvature is needed to perform bending operations. However, in actual use, it is still insufficient due to structural and design limitations. The pressing wheels of the cold bending machines for bending are mostly fixed on the operating table. When bending seismic brackets of different specifications, the fixed pressing wheels result in a fixed bending position of the pressing wheels on the seismic bracket, and it cannot be ensured that the bending position is located at the center of the seismic bracket, which will affect the bending quality of the seismic bracket and even cause deformation of the seismic bracket. Therefore, improvements are needed. Utility Model Content

[0028] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figures 1 to 5 As shown, the utility model provides a cold bending machine for an anti-seismic bracket with adjustable curvature, comprising:

[0030] A support leg 1, with an operating table 2 fixedly mounted on the top of the support leg 1;

[0031] An adjusting mechanism 3, which is arranged at the bottom end of the operating table 2;

[0032] The driving mechanism 4 is arranged on the right side of the bottom end of the operating table 2;

[0033] Among them, the adjustment mechanism 3 includes a fixed frame 301, which is fixedly sleeved inside the operating table 2, and the left and right ends of the fixed frame 301 are movably sleeved with extension columns 302 respectively. The top of the extension column 302 passes through the fixed frame 301 and extends to the outside of the fixed frame 301 and is fixedly installed with a lifting plate 303. The outer surface of the lifting plate 303 is movably sleeved with the inner surface of the operating table 2. A vertical plate 304 is fixedly installed in the middle of the bottom end of the lifting plate 303. The bottom end of the vertical plate 304 is movably connected to the bottom end of the fixed frame 301. A long groove 305 is opened inside the bottom end of the vertical plate 304. The middle end of the long groove 305 is movably sleeved with a round rod 306, and the round rod 306 will move the lifting plate 303.

[0034] When the round rod 306 rotates, since the round rod 306 is movably connected to the inner surface of the long groove 305, the inner surface of the long groove 305 will be subjected to a thrust as the round rod 306 rotates, so that the vertical plate 304 moves upward along the inner surface of the fixed frame 301 with the lifting plate 303 and the extension column 302. The cooperation between the fixed frame 301 and the extension column 302 can limit the movement of the lifting plate 303 to prevent the lifting plate 303 from detaching. With the mutual cooperation of various mechanisms, the bending position of the cold bending machine is adjusted, thereby improving the bending quality of the cold bending machine.

[0035] Wherein, the driving mechanism 4 includes:

[0036] A driving motor 401 is fixedly mounted on the right side of the bottom end of the operating table 2, and a driving shaft 402 is fixedly sleeved on the other end of the output shaft of the driving motor 401;

[0037] The disc 403 is fixedly sleeved on the outer surface of the driving shaft 402 , and the inner surface of the bottom end of the disc 403 is fixedly sleeved on the right side of the outer surface of the round rod 306 .

[0038] When the driving motor 401 is started, the driving shaft 402 will drive the disc 403 to rotate, so that the disc 403 drives the round rod 306 to rotate together.

[0039] Among them, a limit plate 5 is fixedly installed on the right side of the top of the lifting plate 303, a limit block 6 is movably sleeved on the left side inside the limit plate 5, a mounting plate 7 is fixedly installed on the top of the limit block 6, and a pressure wheel 8 is movably sleeved inside the mounting plate 7.

[0040] The inner surface of the limiting plate 5 and the outer surface of the limiting block 6 are both smooth, ensuring that the limiting block 6 will not get stuck when moving along the inside of the limiting plate 5 .

[0041] Among them, a fixed plate 9 is fixedly installed on the left side of the top of the lifting plate 303, a hydraulic cylinder 10 is fixedly installed on the left end of the fixed plate 9, the right end of the hydraulic cylinder 10 penetrates the fixed plate 9 and extends to the outside of the fixed plate 9 and is fixedly connected to the left end of the mounting plate 7.

[0042] When the hydraulic cylinder 10 is started, it will generate a thrust on the mounting plate 7, pushing the mounting plate 7 to move along the inner surface of the limiting plate 5 with the pressure wheel 8 and the limiting block 6, thereby achieving the bending of the anti-seismic bracket.

[0043] Among them, support plates 11 are fixedly installed on the left and right sides of the top of the operating table 2, and a first motor 12 is fixedly installed on the top of the support plate 11. The other end of the output shaft of the first motor 12 is fixedly sleeved with a rotating shaft 13. The bottom end of the rotating shaft 13 penetrates the support plate 11 and extends to the inside of the support plate 11. The outer surface of the rotating shaft 13 is fixedly sleeved with a roller 14, and the roller 14 is movably sleeved on the inner surface of the support plate 11.

[0044] When the first motor 12 is started, the rotating shaft 13 drives the roller 14 to rotate, thereby realizing continuous bending of the anti-seismic bracket.

[0045] Among them, the first bracket 15 and the second bracket 16 are fixedly installed on the left and right sides of the top of the operating table 2, and the first clamping roller 17 is movably sleeved on the bottom ends of the first bracket 15 and the second bracket 16, and the top ends of the first bracket 15 and the second bracket 16 are movably sleeved on the U-shaped frame 18. There are two U-shaped frames 18, and the bottom ends of the two U-shaped frames 18 are movably sleeved on the second clamping roller 19, and the top ends of the two U-shaped frames 18 pass through the first bracket 15 and the second bracket 16 respectively and extend to the outside of the first bracket 15 and the second bracket 16, and the tops of the opposite surfaces of the two U-shaped frames 18 are fixedly installed with a connecting plate 20.

[0046] Due to the existence of the second bracket 16 and the second clamping roller 19, the anti-vibration bracket is pressed tightly, and the existence of the connecting plate 20 can ensure that the two U-shaped frames 18 can move synchronously.

[0047] Among them, a second motor 21 is fixedly installed on the top of the right end of the second bracket 16, and a threaded rod 22 is fixedly sleeved on the other end of the output shaft of the second motor 21. The left end of the threaded rod 22 passes through the second bracket 16 and the first bracket 15 and extends to the left side of the first bracket 15. A movable block 23 is threadedly sleeved on the middle part of the outer surface of the threaded rod 22. A limiting rod 24 is movably sleeved inside the movable block 23. The left and right ends of the limiting rod 24 are respectively fixedly sleeved inside the top ends of the first bracket 15 and the second bracket 16. A connecting rod 25 is hinged on the top end of the movable block 23. The other end of the connecting rod 25 is hinged to the middle part of the bottom end of the connecting plate 20. The movable block 23 will move the connecting plate 20.

[0048] When the second motor 21 is started, the threaded rod 22 will rotate, so that the movable block 23 threadably connected to the threaded rod 22 moves along the outer surface of the limiting rod 24 with the connecting rod 25, and then the other end of the connecting rod 25 generates a pulling force on the connecting plate 20, pulling the connecting plate 20 and the U-shaped frame 18 to move downward.

[0049] The working principle and use process of this utility model:

[0050] First, the operator places the anti-seismic bracket between the second bracket 16 and the second clamping roller 19 and fits it with the roller 14. Then the operator starts the second motor 21 to rotate the threaded rod 22, so that the movable block 23 threadedly connected to the threaded rod 22 moves along the outer surface of the limit rod 24 with the bottom end of the connecting rod 25, thereby causing the top end of the connecting rod 25 to generate a pulling force on the connecting plate 20, pulling the connecting plate 20 and the two U-shaped frames 18 to move downward along the inner surfaces of the first bracket 15 and the second bracket 16 respectively, until the second clamping roller 19 cooperates with the second bracket 16 to press the anti-seismic bracket, thereby realizing automatic pressing and fixing of the anti-seismic bracket, so that the operator does not need to use bolts, thereby improving the convenience of the cold bending machine.

[0051] Then the operator starts the driving motor 401, so that the driving shaft 402 drives the disc 403 and the round rod 306 to rotate. At this time, the outer surface of the round rod 306 will generate a thrust on the inner wall of the long groove 305, pushing the vertical plate 304 to move upward along the inner surface of the fixed frame 301 with the lifting plate 303 and the extension column 302 until the pressure wheel 8 at the top of the lifting plate 303 is aligned with the center position of the seismic support. Then the operator can start the hydraulic cylinder 10 and the first motor 12 to start the continuous bending operation of the seismic support. With the mutual cooperation of various mechanisms, the bending position of the cold bending machine is adjusted, thereby ensuring that the bending position of seismic supports of different specifications is located at the center of the seismic support, thereby improving the bending quality of the cold bending machine.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
