Description

Technical Field

[0001] The utility model relates to the technical field of rolling arc machines, and particularly relates to an upper pressure roller adjusting mechanism of a rolling arc machine. Background Technique

[0002] A rolling arc machine is a metal profile cold bending device. Based on the principle that three points determine a circle, it continuously bends materials, so it is widely used in industrial processing and manufacturing.

[0003] During use, by adjusting the up and down position of the adjusting roller, the relative distance between it and the driving roller can be changed. When bending, the material is placed between the driving roller and the adjusting roller, and the adjusting roller is gradually pressed down to bend the material into the required radius. Commonly, a single threaded rod is used to drive the adjusting roller to move up and down. Long-term movement will cause the balance of the adjusting roller to become worse and the operation angle to be single. Therefore, we propose an upper pressure roller adjusting mechanism of a rolling arc machine to improve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an upper pressure roller adjusting mechanism of a rolling arc machine to solve the problems raised in the above background technique.

The bottom of the second lifting screw rod is connected with a wheel frame body, and an upper auxiliary wheel is installed inside the wheel frame body.

[0010] Preferably, the second lifting screw rod is inserted into the inner part of the upper connecting frame and connected with the wheel frame body at the bottom end inside the upper connecting frame. The second lifting screw rod rotates inside the upper connecting frame to drive the wheel frame body to lift below the upper connecting frame. The upper auxiliary wheel inside the wheel frame body contacts with the upper adjusting roller inside the upper support seat.

[0011] Preferably, a lower fixing roller is installed inside the lower support frame body. A sleeve frame is sleeved outside the lower fixing roller. A cleaning brush is installed inside the sleeve frame. Fixing bolts are inserted into the top end and the bottom end of the sleeve frame. Moving handles are installed at the front end and the rear end of the sleeve frame.

[0012] Preferably, the sleeve frame carrying the cleaning brush inside is sleeved outside the lower fixing roller. The fixing bolts penetrate through the top end and the bottom end of the sleeve frame to fix the sleeve frame outside the lower fixing roller. The moving handles drive the sleeve frame and the cleaning brush to slide outside the lower fixing roller.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The upper pressure roller adjusting mechanism of this kind of rolling arc machine not only realizes the lifting adjustment function, realizes the rotation assistance function, but also realizes the external cleaning function;

[0014] (1) By setting the lifting adjustment structure, the present utility model has the following advantages: When in use, two groups of rotating handles are rotated simultaneously to rotate two groups of first lifting screw rods at the front, rear, left and right sides of the upper support seat.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1: Please refer to Figures 1-4 , an upper pressure roller adjustment mechanism of a rolling arc machine, including a lower support frame body 1 and an upper support seat 3. A connecting slot 18 is opened at the top end of the lower support frame body 1. First lifting screw rods 2 are arranged at the front and rear ends on both sides of the upper support seat 3. A rotating handle 19 is installed at the top end of the first lifting screw rod 2. Connecting plugs 17 are installed on both sides of the bottom of the upper support seat 3. An upper adjusting roller 7 is installed inside the upper support seat 3;

[0024] The connecting insertion blocks 17 on both sides of the bottom of the upper support base 3 are inserted into the connecting slots 18 on both sides of the top end of the lower support frame body 1. The first lifting screw rod 2 is inserted through the front and rear ends of the upper support base 3 to connect with the top end of the lower support frame body 1. Rotating the turning handle 19 drives the first lifting screw rod 2 to rotate on the top end of the lower support frame body 1, driving the upper support base 3 to lift and lower on the top of the lower support frame body 1. The upper adjusting roller 7 lifts and lowers on the top of the lower support frame body 1 through the upper support base 3.

[0025] Specifically, as Figure 1 and Figure 2 shown, by setting the lifting and adjusting structure, when in use, the two groups of turning handles 19 are rotated simultaneously to rotate the two groups of first lifting screw rods 2 at the front and rear ends on both sides of the upper support base 3. The first lifting screw rods 2 rotate on both sides of the top of the lower support frame body 1 to drive the upper support base 3 to slide outside the first lifting screw rods 2, lift and lower on the top of the lower support frame body 1, and make the connecting insertion blocks 17 at the bottom of the upper support base 3 slide in the connecting slots 18 at the top end of the lower support frame body 1, so as to adjust the positions of the lower fixing roller 8 inside the lower support frame body 1 and the upper adjusting roller 7 inside the upper support base 3, thus realizing the lifting and adjusting function.

[0026] Embodiment 2: An upper connecting frame 4 is installed at the top end of the upper support base 3. A second lifting screw rod 5 is inserted into the upper connecting frame 4. A wheel frame body 20 is connected to the bottom of the second lifting screw rod 5. An upper auxiliary wheel 6 is installed inside the wheel frame body 20.

[0027] The second lifting screw rod 5 is inserted into the upper connecting frame 4 to connect with the wheel frame body 20 at the bottom end inside the upper connecting frame 4. The second lifting screw rod 5 rotates inside the upper connecting frame 4 to drive the wheel frame body 20 to lift and lower below the upper connecting frame 4. The upper auxiliary wheel 6 inside the wheel frame body 20 contacts the upper adjusting roller 7 inside the upper support base 3.

[0028] Specifically, as Figure 1 and Figure 3 shown, by setting the rotating auxiliary structure, when in use, by rotating the second lifting screw rod 5 inside the upper connecting frame 4, it drives the wheel frame body 20 at the bottom of the second lifting screw rod 5 to lift and lower inside the upper connecting frame 4, driving the upper auxiliary wheel 6 installed inside the wheel frame body 20 to contact the upper adjusting roller 7 inside the upper support base 3 at the bottom of the upper connecting frame 4. While the upper adjusting roller 7 rotates inside the upper support base 3, it rotates with the upper auxiliary wheel 6 at the bottom of the wheel frame body 20, thus realizing the rotating auxiliary function.

[0029] Embodiment 3: A lower fixing roller 8 is installed inside the lower support frame body 1. A sleeve frame 11 is sleeved outside the lower fixing roller 8. A cleaning brush 23 is installed inside the sleeve frame 11. Fixing bolts 22 are inserted through the top end and the bottom end of the sleeve frame 11. Moving handles 21 are installed at the front and rear ends of the sleeve frame 11.

[0030] The sleeve frame 11 carries an internal cleaning brush 23 which is sleeved outside the lower fixed roller 8. The fixing bolt 22 passes through the top and bottom of the sleeve frame 11 to fix the sleeve frame 11 outside the lower fixed roller 8. The moving handle 21 drives the sleeve frame 11 and the cleaning brush 23 to slide outside the lower fixed roller 8.

[0031] Specifically, as Figure 1 and Figure 4 shown, by setting up the external cleaning structure, when in use, the sleeve frame 11 and the internal cleaning brush 23 are sleeved outside the lower fixed roller 8. Then the fixing bolt 22 is inserted into the upper and lower ends of the bottom of the sleeve frame 11 to fix the sleeve frame 11 outside the lower fixed roller 8. Then, through the moving handle 21, the sleeve frame 11 and the cleaning brush 23 slide outside the lower fixed roller 8 to clean the outside of the lower fixed roller 8, thus realizing the external cleaning function.

[0032] Working principle: When the present utility model is in use, the second lifting screw 5 rotates inside the upper connecting frame 4, driving the wheel frame body 20 at the bottom of the second lifting screw 5 to lift inside the upper connecting frame 4, driving the upper auxiliary wheel 6 installed inside the wheel frame body 20 to contact the upper adjusting roller 7 inside the upper support seat 3 at the bottom of the upper connecting frame 4. At the same time, the lower auxiliary wheel 9 is supported by the lower adjusting frame 10 and the lower fixed roller 8 inside the lower support frame body 1. The material to be rolled into an arc is placed above the lower fixed roller 8 inside the lower support frame body 1. Then, by simultaneously rotating the two rotating handles 19, the two first lifting screws 2 at the front, rear, left, and right ends on both sides of the upper support seat 3 are rotated. The first lifting screws 2 rotate on both sides of the top of the lower support frame body 1 to drive the upper support seat 3 to slide outside the first lifting screws 2 and lift on the top of the lower support frame body 1, so that the connecting plug 17 at the bottom of the upper support seat 3 slides in the connecting slot 18 at the top end of the lower support frame body 1, to adjust the positions of the lower fixed roller 8 inside the lower support frame body 1 and the upper adjusting roller 7 inside the upper support seat 3, so as to clamp the material by the upper adjusting roller 7 and the lower fixed roller 8 and adjust the arc of the material. By rotating the motor 14 to drive the driving pulley 13 to rotate, the driving pulley 13 drives the auxiliary pulley 12 on the left side of the lower support frame body 1 to rotate through the connecting belt 16, and the auxiliary pulley 12 drives the two lower fixed rollers 8 inside the lower support frame body 1 to rotate, conveying the material between the upper adjusting roller 7 and the lower fixed roller 8. When not in use, the sleeve frame 11 and the internal cleaning brush 23 are sleeved outside the lower fixed roller 8. Then the fixing bolt 22 is inserted into the upper and lower ends of the bottom of the sleeve frame 11 to fix the sleeve frame 11 outside the lower fixed roller 8. Then, through the moving handle 21, the sleeve frame 11 and the cleaning brush 23 slide outside the lower fixed roller 8 to clean the outside of the lower fixed roller 8.
