Description

Technical Field

[0001] This utility model relates to a bending device for bending galvanized T-bend templates, belonging to the technical field of auxiliary equipment for steel rolling production in the metallurgical industry. Background Technology

[0002] On a cold-rolled strip hot-dip galvanizing production line, the export T-bend quality inspection is a crucial task, serving as the final quality checkpoint. T-bend inspection is an effective method for checking for dezincification defects in the strip. First, a 20-30mm wide strip is taken from the entire coil or its tail for a long T-bend. A 300mm long sample is then cut to make short T-bends at both ends. These are then bent 180 degrees, compacted, and inspected under light to check for dezincification defects in the strip's center and sides. Strips thinner than 1.5mm can be manually bent 180 degrees, but strips thicker than 1.5mm require an F-shaped tube. Bending the strip manually with this tube is inefficient and time-consuming. For strips thicker than 3.5mm, bending the T-bend with only a small tube is extremely difficult for workers. Utility Model Content

[0003] The purpose of this invention is to provide a bending device for bending galvanized T-bend templates. The device uses the torque provided by a geared motor to replace manual application of yield force to the T-bend strip, thereby achieving the purpose of bending T-bends, reducing the labor intensity of operators, and solving the problems existing in the background technology.

[0004] The technical solution of this utility model is:

[0005] A bending device for bending galvanized T-bend templates includes a motor, a worktable, working shafts, fixed shafts, and a turntable. The turntable is mounted on the surface of the worktable, and a motor connected to the turntable is mounted under the worktable surface. There are two working shafts and two fixed shafts. The two working shafts are fixed on the turntable, with one working shaft located at the center of the turntable. The two fixed shafts are fixed on the surface of the worktable. The distance L between the working shaft located at the center of the turntable and the two fixed shafts is determined according to the thickness of the T-bend template.

[0006] The distance L between the working shaft located at the center of the turntable and the two fixed shafts is less than or equal to 9mm.

[0007] The center distance between the two working shafts is 30-40mm, and the center distance between the two fixed shafts is 50-70mm.

[0008] The height of the two working shafts and the two fixed shafts is greater than the width of the T-bend template.

[0009] The upper surface of the turntable is on the same horizontal plane as the worktable surface.

[0010] The beneficial effects of this utility model are: using the torque provided by the geared motor to replace the manual application of yield force to the T-bend strip, thereby achieving the purpose of bending into a T-bend and reducing the labor intensity of operators.

[0017] The present invention will be further described below with reference to the accompanying drawings and examples.

[0018] See attached document Figure 1-5 A bending device for bending galvanized T-bend templates includes a motor 1, a worktable 2, a working shaft 4, a fixed shaft 5, and a turntable 6. The turntable 6 is provided on the surface of the worktable 2, and the motor 1, which is driven and connected to the turntable 6, is provided under the surface of the worktable 2. There are two working shafts 4 and two fixed shafts 5. The two working shafts 4 are fixed on the turntable 6, with one working shaft 4 located at the center of the turntable 6. The two fixed shafts 5 are fixed on the surface of the worktable 2. The distance L between the working shaft 4 located at the center of the turntable 6 and the two fixed shafts 5 is determined according to the thickness of the T-bend template.

[0019] In this embodiment, refer to the appendix Figure 1-5 The upper surface of turntable 6 is on the same horizontal plane as the table surface of worktable 2. The two working shafts 4 and the two fixed shafts 5 are all round steel with a diameter of 25mm and a length of 80mm. The center distance between the two working shafts 4 is 30-40mm, and the center distance between the two fixed shafts 5 is 50-70mm. The distance L between the working shaft 4 located at the center of turntable 6 and the two fixed shafts 5 is less than or equal to 9mm. Motor 1 is a geared motor with a reduction gearbox, fixed to the underside of the table surface of worktable 2 by four M8*30 bolts.

[0020] When bending the T-bend template, press any button on control switch 3 to rotate motor 1 and return working shaft 4 to its initial position. Place the strip to be bent between working shaft 4 and fixed shaft 5, adjust the bending position, and press the reverse button on control switch 3 to bend the strip. (See attached diagram.) Figure 5 As shown, after the bending angle is satisfied, press the forward rotation button of control switch 3, rotate to the appropriate position, remove the strip, and restore the initial position of the working shaft 4; then place the strip between the working shaft 4 and the fixed shaft 5, adjust the required bending position, and perform the bending operation at the next position; the whole bending process is simple to operate and greatly reduces the labor intensity of the operator.
