A spring 21 is provided inside the telescopic cavity 20, and a telescopic rod 22 is connected to the top of the spring 21, and a limiting roller 23 is connected to the end of the telescopic rod 22.

[0025] The present invention adjusts the position of the transverse roller 15 by the screw 17, clamps and fixes the steel in the longitudinal direction, and the limiting roller 23 is always in close contact with the steel under the elastic force of the spring 21, limiting the steel in the transverse direction, thereby ensuring the stability of the steel during the processing, and the steel is not easily displaced during the bending process, thereby ensuring the normal cold bending of the steel, avoiding deviation in the bending angle of the steel, improving the qualified rate of steel processing, avoiding waste of steel, and protecting users from economic losses.

[0026] Please refer to Figure 1 A universal wheel 24 is fixed to the bottom of the base plate 1, and the universal wheel 24 is installed at the four corners of the base plate 1. Through the installation of the universal wheel 24, it is convenient for the user to move the cold bending machine, which improves the maneuverability of the cold bending machine and brings convenience to the user.

[0027] Please refer to Figure 1 The traction block 3 and the slide 2 form a sliding structure, and the traction block 3 and the mounting plate 6 are integrated. The moving trajectory of the traction block 3 is limited by the slide 2 to ensure the normal use of the position adjustment function of the top roller 10.

[0028] Please refer to Figure 2 The traction block 3 and the adjusting rod 4 are threadedly connected, and the adjusting rod 4 and the traction block 3 are arranged at the same horizontal plane. The first motor 5 drives the adjusting rod 4 to rotate, and then drives the traction block 3 to move horizontally, and adjusts the position of the top roller 10 to achieve the purpose of changing the curvature of the steel, thereby meeting the different processing needs of users.

[0029] Please refer to Figure 2The first bevel gear 8 and the second bevel gear 9 are meshed and connected, and the first bevel gear 8 and the second bevel gear 9 are arranged perpendicular to each other. The second motor 7 drives the first bevel gear 8 to rotate, and then drives the top roller 10 to rotate under the transmission of the second bevel gear 9, bending the steel while conveying the steel, ensuring the smooth processing of the steel.

[0030] Please refer to Figure 3 The anti-slip sleeve 12 and the top roller 10 form a sliding installation structure through the installation groove 11, and the anti-slip sleeve 12 and the top roller 10 are tightly fitted. The anti-slip sleeve 12 is slidably installed on the outside of the top roller 10 along the installation groove 11, which increases the friction between the top roller 10 and the steel, preventing the steel from slipping during transportation and affecting the smooth processing.

[0031] Please refer to Figure 4 The cross roller 15 and the screw 17 form a linkage structure through the pull ring 16, and the screw 17 and the nut 18 are threadedly connected. By rotating the screw 17, the pull ring 16 drives the cross roller 15 to move up under the action of the nut 18, so as to adjust the spacing of the cross rollers 15 according to the width of different steel products to meet the processing needs of the cold bending machine for steel products of different sizes.

[0032] Please refer to Figure 5 The transverse roller 15 and the limiting groove 19 form a sliding structure, and the transverse roller 15 fits tightly against the limiting groove 19. The setting of the limiting groove 19 ensures that the transverse roller 15 can move up and down smoothly and efficiently, and can fix the transverse roller 15 to prevent the transverse roller 15 from shifting when clamping the steel.

[0033] Please refer to Figure 4 The pull ring 16 and the screw 17 are movably connected, and the pull ring 16 and the cross roller 15 are fixedly connected. The movably connected pull ring 16 and the screw 17 facilitates the user to longitudinally adjust the position of the cross roller 15.

[0034] Please refer to Figure 4 The limiting roller 23 and the telescopic chamber 20 form an elastic telescopic structure through the spring 21, and the spring 21 is arranged at the same horizontal plane as the telescopic chamber 20. Through the setting of the spring 21, the limiting roller 23 can always fit with the steel during steel processing, further ensuring the fixed stability of the steel during the processing.

[0035] Working principle: First, according to the curvature requirement, turn on the first motor 5, the first motor 5 drives the adjusting rod 4 to rotate, and then drives the traction block 3 to move horizontally along the slide 2, and the mounting plate 6 drives the top roller 10 to move, and adjusts the position of the top roller 10 to achieve the purpose of changing the curvature of the steel. Then, slide the anti-slip sleeve 12 along the mounting groove 11 and install it on the outside of the top roller 10 to increase the friction between the top roller 10 and the steel to prevent the steel from slipping during transportation. At this time, place the steel in the two transverse rollers 15 in the limit part 14, rotate the screw 17, and under the action of the nut 18 The pull ring 16 drives the transverse roller 15 to move downward, clamping and fixing the steel in the longitudinal direction, and the limiting roller 23 is always in close contact with the steel under the elastic force of the spring 21, limiting the steel in the transverse direction, ensuring the stability of the steel during processing. Then the second motor 7 is turned on, and the second motor 7 drives the first bevel gear 8 to rotate, and then drives the top roller 10 to rotate under the transmission of the second bevel gear 9, bending the steel while conveying it. The steel is bent with the cooperation of the top roller 13 and the limiting parts 14, and the user can move the cold bending machine through the universal wheel 24.
