[0025] (1) This case sets up a relative bending component to solve the problem of using a mold to apply relative force to the two ends of the material. This bending method will cause greater friction on the two ends of the material during construction, causing greater wear on the surface of the material, affecting the service life of the U-shaped material in the later use. When the material needs to be bent, the torque motor drives the mounting plate to move under force. During the movement of the mounting plate under force, the clamping block and the concave wheel drive the two ends of the material to perform relative bending. During the bending process, the two ends of the material move relative to the concave wheel. During the relative movement of the two ends of the material and the concave wheel under force, not only the relative friction resistance between the material and the clamping block is reduced, but also the above-mentioned situation is avoided;

[0026] (2) By setting up: an adjustment component, the existing bending device is often inconvenient to fix according to the length of the material, so that it is not convenient to fix shorter materials when bending and fixing, and it is not convenient to fix the same material for multiple bending. When the material is short and the relative interval distance between the relative bending components needs to be adjusted, the operator controls the motor to work. During the operation of the motor, the ball screw and the ball nut drive the relative bending components to move relative to each other. During the relative movement of the relative bending components, not only the above situation is avoided, but also the materials of different sizes can be effectively bent relative to each other;

[0027] (3) The protective structure is provided with a mounting frame and a protective door, thereby solving the problem that the existing bending device is basically exposed to the outside environment to bend the material, which may cause danger to the operator when the material is separated during the bending process. When the material is bent, the protective door and the mounting frame are closed. When the protective door and the mounting frame are closed and connected, it not only has an isolation and protection effect on the operator but also avoids the above situation;

[0028] (4) The protection structure is provided with: a linear motor, an adjusting cylinder and a bending die, thereby solving the problem that the relative bending assembly can only perform U-shaped bending on the material. When the material needs to be bent at a right angle or in different shapes, the operator manually installs and sets different bending dies and adjusting cylinders, and controls the linear motor to drive the adjusting cylinder to the corresponding position during operation. By controlling the adjusting cylinder and the bending die to be driven synchronously by force, the material is bent into different shapes and states, and the above-mentioned components are used to avoid the above-mentioned situation at the same time.

[0045] The above scheme is further developed in sequence, wherein the slider 2016 passes through the slide rod 2017 and is arranged inside the connecting frame 2011, and the slide rod 2017 is arranged in a logarithmic manner, wherein the number of the slide rods 2017 is matched with the number of the sliders 2016 for installation and setting, and the slider 2016 and the slide rod 2017 that are arranged at the same time also play a stable installation and driving adjustment effect on the connecting disk 2015.

[0046] The above scheme is further developed. The relative bending component 202 includes a clamping block 2021 for relatively clamping the telescopic ladder processing parts, and the inner side of the clamping block 2021 is movably provided with a concave wheel 2023 through a connecting piece 2022.

[0048] In the above scheme, when the material processed by the telescopic ladder needs to be bent, the operator opens the protective door 104 and controls the motor 2013 to work according to the length of the material. During the operation of the motor 2013, the ball screw 2012 and the ball nut 2014 drive the connecting plate 2015 to carry the slider 2016, which is subjected to force relative movement with the slider 2017 and the connecting frame 2011, and the torque motor 2026 is synchronously driven relative to the connecting plate 2015 during the force movement. The operator stops adjusting the operation of the motor 2013 by observing the scale line 1010. At this time, the operator controls the driving cylinder 2024 to work again. During the operation of the driving cylinder 2024, the connecting piece 2022 and the concave wheel 2023 carried by the clamping block 2021 are subjected to force relative movement to place and clamp the material. When the material is clamped, the operator closes the protective door 104 to control The torque motor 2026 is operated.

When the material needs to be bent into other shapes, the operator manually rotates the bending mold 109 to force the threaded rod 108 and the adjusting cylinder 106 and the connecting groove 107 to rotate and separate. After the bending mold 109 is separated by force, the operator connects the bending mold 109 to be bent with the adjusting cylinder 106 through the placement frame 102. When the bending mold 109 is far away, the operator controls the linear motor 105 to drive the adjusting cylinder 106 to the corresponding position and controls the adjusting cylinder 106 and the motor 2013 to work, so as to bend the material into other different shapes.
