[0004] Furthermore, the bending template is in the shape of an inverted V, with an included angle of 45°.

[0005] Furthermore, the length of the inclined side of the bending template is 42-48mm, and its height is 31-34mm.

[0006] Furthermore, the bending pressure plate is in the shape of an inverted V, and the lengths of its two inclined sides can completely cover the inclined sides of the bending pressure plate.

[0007] Furthermore, the length of the bending template is greater than the width of the strip steel, and the length of the support tube is greater than the length of the bending template.

[0008] Furthermore, the support base is provided with a support column inside to prevent deformation of the arc-shaped groove.

[0009] Furthermore, the fixing frame includes a fixing rod and a crossbar. The two bottom plates at both ends are provided with fixing rods. The two ends of the crossbar are respectively installed on the two fixing rods. The bending pressure plate is pulled on the crossbar, and the height of the crossbar is such that the bending pressure plate presses precisely on the surface of the bending template.

[0010] Furthermore, a sliding rod is longitudinally provided on the top of the bending pressure plate, and a traction rod is transversely provided on the top of the traction rod. A sliding groove is provided inside the crossbar along its length direction.

[0023] like Figure 1-5 As shown, a strip bending device includes a base plate 16, a support base 11, a support tube 12, and a bending pressure plate 14; wherein: There are multiple base plates 16, all of which are installed on the base 3 at the site of the No. 2 walking beam leveling in the cold rolling mill. The installation method can be welding. There are multiple support seats 11, the number of which matches the base plate 16. Each support seat 11 is installed on its respective base plate 16. The top surface of each support seat 11 is provided with an arc-shaped groove 111. The support seat 11 and the base plate 16 can be connected by bolts 112. The support seat 11 is designed with a positioning pin 113 that cooperates with the base plate 16 to prevent misalignment when operating the bending head 6. The support tube 12 is axially embedded in each arc groove 111. The top surface of the support tube 12 is axially provided with a bending template 13 for bending the strip steel 5 head 6. The support tube 12 and the arc groove 111, the bending template 13 and the support column 114 can be welded. The bending plate 14 can be axially moved along the support tube 12 and installed on a fixed frame 15 to bend the strip steel 5 with the head 6 along the surface of the bending template 13 using its gravity.

[0024] like Figure 2 , 5 As shown, the bending template 13 is in the shape of an inverted V, and the included angle formed by it is 45°.

[0025] In one embodiment, the strip steel 5 produced by the cold rolling mill has a width of 1270–1360 mm; in this device, the length of the support tube 12 ranges from 1580–1620 mm, the diameter ranges from 98–104 mm, and the corresponding arc groove 111 has a diameter range of 98–104 mm; the length of the bending template 13 ranges from 1480–1520 mm, the length of the inclined side ranges from 42–48 mm, and the height ranges from 31–34 mm.

[0026] like Figure 3 , 5 As shown, the bending pressure plate 14 is inverted V-shaped, and the lengths of its two inclined sides can completely cover the inclined sides of the bending pressure plate 14.

[0027] The length of the bending template 13 is greater than the width of the strip steel 5, and the length of the support pipe 12 is greater than the length of the bending template 13.

[0028] Preferably, the support tube 12 has a length of 1600mm and a diameter of 100mm, the arc groove 111 has a diameter of 100mm, the bending template 13 has a length of 1500mm, a hypotenuse length of 45mm, and a height of 33mm.

[0029] In one embodiment, the support base 11 has a support column 114 inside to prevent deformation of the arc groove 111. The support column 114 supports the arc groove 111, so that the support tube 12 has good support strength. In addition, the support base 11 is designed to be hollow in the middle with a thickness of 10mm. The support column supports the support strength requirements, reduces weight, facilitates installation, and reduces manufacturing costs.

[0030] like Figure 2 , 4 As shown in Figure 5, the fixing frame 15 includes a fixing rod 151 and a crossbar 152. The two bottom plates 16 on both ends are provided with fixing rods 151. The two ends of the crossbar 152 are respectively installed on the two fixing rods 151. The bending pressure plate 14 is pulled on the crossbar 152, and the height of the crossbar 152 is such that the bending pressure plate 14 presses exactly on the surface of the bending template 13.

[0031] The fixing rod 151 is installed on the base plate 16 by bolts 112. The horizontal bar 152 is installed at a height of 100-120mm, which facilitates the operator to pull the bending pressure plate 14 on the horizontal bar 152 to perform bending operations.

[0032] In one embodiment, a sliding rod 141 is longitudinally arranged on the top of the bending pressure plate 14, a traction rod 142 is transversely arranged on the top of the traction rod 142, a sliding groove 153 is formed in the crossbar 152 along its length direction, the sliding rod 141 is longitudinally inserted into the sliding groove 153, and both ends of the traction rod 142 are transversely inserted out of the sliding groove 153.

[0033] Specifically, the sliding groove 153 in the crossbar 152 is a T-shaped groove. The longitudinal groove is used for the sliding rod 141 to move, and the transverse groove is used to limit the position of the traction rod 142. The operator holds the traction rod 142 to push it to move in the sliding groove 153, thereby driving the bending plate 14 to bend the strip steel 5 with the head 6 along the bending template 13.

[0034] In another embodiment, both fixed rods 151 extend upward and are provided with suspension rods 154 along the direction of the crossbar 152. The suspension rods 154 are provided with connecting rods 156 connected to the crossbar 152 at the position opposite to the end of the bending template 13. The connecting rods 156 are provided with speed limiting grooves 157 that communicate with sliding grooves 153. The suspension rods 154 are provided with suspension grooves 155 that communicate with speed limiting grooves 157. The sliding rods 141 and traction rods 142 can move from the suspension grooves 155 to the sliding grooves 153.

[0035] The suspension groove 155 and the sliding groove 153 have the same shape, both being T-shaped grooves, to facilitate the movement of the sliding rod 141 and the traction rod 142; the speed limiting groove 157 is a transverse T-shaped groove, allowing the sliding rod 141 and the traction rod 142 to move from the suspension groove 155 to the speed limiting groove 157.

[0036] like Figure 4 As shown, the inner wall of the speed limiting groove 157 is provided with a deceleration pad 158 to limit the descent speed of the traction rod 142. After the sliding rod 141 and the traction rod 142 enter the speed limiting groove 157, they will move downwards rapidly under the action of the gravity of the bending pressure plate 14; therefore, the deceleration pad 158 can increase the friction between it and the sliding rod 141 and the traction rod 142, thereby limiting the descent speed of the bending pressure plate 14.

[0037] Preferably, the deceleration pad 158 is a rubber pad with an array of protrusions. The protrusions on the rubber pad press against the traction rod 142, causing the bending pressure plate 14 to slowly move downwards onto the bending template 13, avoiding the need for manual movement by the operator and preventing the bending pressure plate 14 from descending rapidly and becoming uncontrollable. The end of the suspension groove 155 near the fixed rod 151 is provided with a limiting groove to prevent the traction rod 142 from sliding freely. When the bending pressure plate 14 is not in use, the traction rod 142 is moved into the limiting groove to prevent the traction rod 142 from sliding freely, and the bending pressure plate 14 is also stored at the end.

[0038] In use, when the steel coil trolley 2 delivers the strip steel 5 to the saddle 4 (the length of the strip steel 5 head 6 is pre-adjusted), and the strip steel 5 head 6 is threaded above the bending template 13, the operator holds the traction rod 142 and moves it out of the limiting groove, and moves the traction rod 142 from the suspension groove 155 and the speed limiting groove 157 to the sliding groove 153. At this time, the bending pressure plate 14 falls on the bending template 13 and uses its gravity to bend the strip steel 5 head 6. The operator operates the traction rod 142 to move it along the crossbar 152 to the other end, thereby completing the bending operation of the strip steel 5 head 6. The traction rod 142 is moved upward along the speed limiting groove 157 and then moved to the limiting groove at the suspension groove 155, thereby retracting the bending pressure plate 14. After the bending plate 14 leaves the strip 5, its head 6 has a certain elasticity, so that the bending angle is between 120° and 150°, forming a good bending effect. This effectively solves the problems of low production efficiency and high labor intensity, and realizes the continuity of steel rolling. At the same time, the bending device 1 has the advantages of strong stability and good convenience. It is easy to install and maintain and reliable in use.
