The support wheel 9 supports the first roller 8 inside the bracket 7, which can improve the carrying capacity of the first roller 8 and avoid the fracture of the rotating connection position of the first roller 8 and the bracket 7 due to the large force when bending;

[0025] In order to facilitate the adjustment of the position of the bracket 7, one end of the two brackets 7 is provided with a second hydraulic telescopic rod 10. The lower ends of the two second hydraulic telescopic rods 10 are connected by a transmission bar 5. One end of the second hydraulic telescopic rod 10 is welded and fixed with the bracket 7. By driving the transmission bar 5, the bracket 7 and the first roller 8 can be rotated synchronously, which can realize stable adjustment of the bracket 7 and stable bending of the round steel;

[0026] In order to avoid the large bearing capacity of the welding position of the bracket 7 and the second hydraulic telescopic rod 10, the lower end of the bracket 7 is embedded in the inside of the transmission bar 5 and is slidably connected with the inside of the transmission bar 5. During the horizontal movement of the second hydraulic telescopic rod 10, the bracket 7 will slide in the inside of the transmission bar 5. By embedding the bracket 7 in the inside of the transmission bar 5, the connection between the bracket 7 and the second hydraulic telescopic rod 10 can be assisted, which can avoid the fracture of the connection position of the second hydraulic telescopic rod 10 and the bracket 7 during the bending of the round steel:

[0027] In order to avoid the friction caused by bending from causing indentation, as shown in Figure 4 The upper end of the two brackets 7 is provided with a sponge 16. The upper end of the sponge 16 is provided with a connecting block 15. The connecting block 15 and the sponge 16 are arrayed with a shunt pipe 19, and the shunt pipe 19 is sealingly connected with the connecting block 15. The lubricant delivered into the connecting block 15 will be shunted by the shunt pipe 19 and evenly enter the inside of the sponge 16. When the sponge 16 with lubricant contacts the round steel, it will lubricate the bending position to avoid indentation caused by friction;

[0028] As shown in Figure 3 One side of the two brackets 7 is provided with a clamping device 4. One side of the clamping device 4 is provided with a motor 3. After the round steel is clamped by the clamping device 4, the motor 3 can drive the round steel to rotate through the clamping device 4. The rotating round steel can contact the sponge 16 with lubricant at the same time to lubricate the bending position;

[0029] Referring to Chinese Patent No. CN206172939U, a screw cap clamping device is described. In this application, the clamping method used is the same as that in the patent application. The patent application is prior art compared to this application. This application does not make any inventions or creations in the clamping part. Therefore, in this application, the principle of clamping the round steel at the clamping device 4 position and the internal structure of the clamping device 4 are not described in detail.

[0030] In addition, a first hydraulic telescopic rod 2 is provided at one end of the motor 3, and the first hydraulic telescopic rod 2 is welded and fixed to the upper end of the base 1. During the rotation and bending of the transmission bar 5, the first hydraulic telescopic rod 2 can extend to further avoid friction causing indentations.

[0031] In order to extract and transport the lubricant, a third hydraulic telescopic rod 12 is provided on one side of the upper end of the connecting block 15, and a connecting rod 11 is provided on the outer side of the third hydraulic telescopic rod 12. The two ends of the connecting rod 11 are welded and fixed to the outer wall of the third hydraulic telescopic rod 12 and the upper end of the base 1, respectively. The connecting rod 11 can support and erect the third hydraulic telescopic rod 12. The extension of the third hydraulic telescopic rod 12 can actively push the sponge 16 to contact the pair of round steel bars to achieve the application of lubricant.

[0032] A storage box 14 is provided on one side of the upper end of the connecting rod 11. A pump 13 is provided between the upper end of the storage box 14 and the connecting block 15. The storage box 14, the pump 13 and the connecting block 15 are sequentially and sealed together. The lubricant stored in the storage box 14 can be extracted by starting the pump 13 and then drawn into the connecting block 15, so that the lubricant can contact the sponge 16 and the round steel.

[0033] To facilitate the fixing and replacement of the sponge 16, a second clip 20 is provided around the outside of the sponge 16, such as... Figure 5 As shown, a first clamping piece 18 is provided on one side of the second clamping piece 20. Threaded rods 17 are provided on both sides of the second clamping piece 20 facing the first clamping piece 18, and the threaded rods 17 pass through and extend to one end of the first clamping piece 18. The outer side of the threaded rod 17 is threadedly engaged with the through position of the first clamping piece 18. When the two threaded rods 17 rotate, they push the first clamping piece 18, adjusting the distance between the first clamping piece 18 and the second clamping piece 20. Adjusting the distance can clamp and fix the sponge 16. By bringing the first clamping piece 18 closer to the second clamping piece 20, the sponge 16 can be fixed. By increasing the distance between the first clamping piece 18 and the second clamping piece 20, the sponge 16 can be removed.

[0034] The second clamp 20 is fixedly connected to the connecting block 15. The connection and support of the connecting block 15 can be achieved simultaneously through the circumferential connection of the second clamp 20.

[0035] To facilitate bending of the round steel between the pair of first rollers 8, such as Figure 2 As shown, the lower middle side of the transmission bar 5 is rotatably connected to the base 1 via a connecting shaft 6. After the transmission bar 5 is rotated by electric drive, the transmission bar 5 can bend round steel by rotating around the connecting shaft 6.

[0036] Working principle: When using the device to bend the round steel used for chain processing, one end of the round steel is clamped by the clamping device 4, and the other end is suspended between a pair of first rollers 8. The extension and retraction of the first hydraulic telescopic rod 2 can push the round steel to the corresponding bending position. The pump 13 draws lubricant from the storage tank 14, and the lubricant is sent into the connecting block 15 and divided by the diverter pipe 19. The divided lubricant is absorbed by the sponge 16. The third hydraulic telescopic rod 12, supported by the connecting rod 11, pushes the sponge 16, so that the sponge 16 with lubricant contacts the round steel at the bending position. The motor 3 starts and... The clamping device 4 drives the round steel to rotate, so that the lubricant surrounds the bent position of the round steel. After the lubricant is applied, the third hydraulic telescopic rod 12 retracts and returns to its original position. By activating a pair of second hydraulic telescopic rods 10, the extension of the second hydraulic telescopic rods 10 can simultaneously push the corresponding first rollers 8. The pair of first rollers 8 clamp the round steel. The electric drive transmission bar 5 rotates, so that the transmission bar 5 rotates around the connecting shaft 6 as the center and bends the round steel. During the bending process, the rotation of the first rollers 8 in the bracket 7 can offset some of the friction, and the lubricant applied by the sponge 16 can further offset the friction, preventing indentations from being generated at the bent position.
