[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 to 3 , the present invention provides a technical solution:

[0020] A component bending device includes a workbench 1 and an L-shaped frame 2 installed on the workbench 1. A fixed seat 3 is arranged above the workbench 1. An installation groove is opened above the fixed seat 3. A bending seat 4 is detachably installed in the installation groove. Through holes are symmetrically opened on the L-shaped frame 2. Two groups of guide rollers 8 are slidably installed inside the through holes for fixing components. An electric push rod is installed at the top of the L-shaped frame 2, and a housing 6 is installed on one side. The output shaft end of the electric push rod 5 penetrates into the L-shaped frame 2 and is installed with a bending head 7. A sliding mechanism for adjusting the distance between the two groups of guide rollers 8 is installed inside the housing 6.

[0021] During work, first select a suitable bending seat 4 and install it in the installation groove above the fixed seat 3. Then place both ends of the component between the two groups of guide rollers 8. Then start the sliding mechanism to work, driving the two groups of guide rollers 8 to move relatively until they contact the two sides of the component, achieving the purpose of clamping, improving the stability of fixation. Then start the electric push rod to drive the bending head 7 to move downward and squeeze the component to complete the bending.

[0022] Two clamping plates 9 are slidably installed inside the installation groove. The bending seat 4 is fixed between the two clamping plates 9. A pull rod 10 is installed on one side of one of the clamping plates 9. A spring is sleeved outside the pull rod 10. One end of the spring is connected to the clamping plate 9, and the other end is connected to the inner wall of the installation groove.

[0023] Electromagnets with opposite magnetic poles are respectively installed inside the two clamping plates 9. A control switch electrically connected to the electromagnet is installed on one side of the fixed seat 3.

[0024] During installation, manually pull the pull rod 10 outwards, place the bending seat 4 between the two clamping plates 9, then release the pull rod 10. Due to the elastic force of the spring, the clamping plates 9 press and fix the bending seat 4. Then, press the control switch to energize the electromagnet. According to the principle of mutual attraction of opposite-sex electromagnets, the clamping force of the two clamping plates 9 is further increased to ensure the stable progress of the bending operation.

[0025] The sliding mechanism includes a bidirectional screw 11 installed in the housing and sliders 12 sleeved at both ends of the bidirectional screw 11 and helically drivingly connected thereto. The guide rollers 8 penetrate through the through holes and extend into the housing 6 and are respectively connected to the sliders 12. A servo motor for driving the bidirectional screw 11 to rotate is installed outside the housing 6. By driving the bidirectional screw 11 to rotate forward and backward by the servo motor, the two sliders 12 are driven to move in the same or opposite directions in the horizontal position, so as to adjust the distance between the two groups of guide rollers 8.

[0026] Finally, several points should be noted: First, in the description of the present application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the communication inside two components, and can be directly connected.
