When the toggle rod 23 is rotated to no longer conflict with the inclined block 212, the slide plate 27 will drive the clamped profile to move into the bending groove 6, and as the cylinder 3 drives the connecting seat 4 and makes the connecting seat The receiving seat 4 drives the bending pressure block 5 to extrude and bend the profile in the bending groove 6. The surface of the body 1 is provided with a control part 2, and the control part 2 includes: a connecting plate 21, an axle rod 22, a toggle rod 23, a limit block 24, a torsion spring 25, a support rod 26, a slide plate 27, a spring 1 28, a pull bar 29, a toggle hole 210, a positioning block 211, a ramp block 212, a clamping plate 213, a vertical rod 214, a bolt 215, a fixing block 216, a cross bar 217, a resistance block 218, and a spring 219.
[0023] The side of the connecting plate 21 close to the connecting seat 4 is fixedly connected to the side of the connecting seat 4, and the side of the connecting plate 21 away from the connecting seat 4 is fixedly connected to the shaft rod 22. When the cylinder 3 continues to push the connecting seat 4 to move downward, the bottom of the toggle rod 23 will contact the inclined portion of the inclined surface block 212, so that the toggle rod 23 rotates with the center line of the shaft rod 22 as the axis. The shaft rod 22 penetrates and is rotatably connected to the toggle rod 23. The support rod 26 is fixedly connected to the surface of the body 1. The end of the support rod 26 away from the surface of the body 1 penetrates and is slidably connected to the slide plate 27. The side of the slide plate 27 is fixedly connected to the pull bar 29. Since the toggle rod 23 is first inserted into the toggle hole 210 and then rotated, the toggle rod 23 will pull the pull rod 29 through the toggle hole 210, and the pull rod 29 will slide along the positioning block 211. At the same time, the pull rod 29 will drive the slide plate 27 to slide together when sliding, and the slide plate 27 will drive the clamped profile to move together when sliding. The pull rod 29 is located on the top surface of one end of the toggle rod 23 and is provided with a toggle hole 210. The side of the positioning block 211 close to the body 1 is fixedly connected to the surface of the body 1. The pull rod 29 passes through the positioning block 211 and is slidably connected. The side of the body 1 is fixedly connected with a ramp block 212. The top surface of the slide plate 27 is fixedly connected with a vertical rod 214, which penetrates and slides with a clamping plate 213, and the surface of the clamping plate 213 is penetrated and threaded with a bolt 215. The profile to be bent is placed between the clamping plate 213 and the slide plate 27, and the bolt 215 is screwed, so that the bolt 215 drives the clamping plate 213 to move downward, and then the clamping plate 213 clamps the profile. The bolt 215 penetrates the slide plate 27 and is threaded. The side of the slide plate 27 close to the body 1 is fixedly connected with a spring 28. When the bending is completed, the bolt 215 is loosened to remove the bent profile, and the torsion spring 25 will pull back the toggle rod 23 when the cylinder 3 rises, and the spring 28 will push the slide plate 27 to reset.

A resistance block 218 is fixedly connected to the end of the cross bar 217 away from the fixed block 216. A spring 219 is fixedly connected between the resistance block 218 and the fixed block 216. When the profile is moved by the slide plate 27 and the clamping plate 213, the edge of the profile will resist the inclined surface of the resistance block 218, causing the resistance block 218 to shrink along the cross bar 217. When the profile is completely located on the inner side of the resistance block 218, the spring 219 will push the resistance block 218 to correct the two sides of the profile. The surface of the connecting plate 21 is fixedly connected to a limit block 24, and a torsion spring 25 is fixedly connected between the limit block 24 and the toggle rod 23. When the bending is completed, the bolt 215 is loosened to remove the bent profile, and the torsion spring 25 will pull back the toggle rod 23 when the cylinder 3 rises, and at the same time, the spring 28 will push the slide plate 27 to reset.The position of the toggle hole 210 is located directly below the toggle rod 23 and is aligned with the toggle rod 23.

[0024] When the cylinder 3 moves downward, it will drive the shaft 22 to move downward together with the connecting plate 21, and when the shaft 22 moves downward, the bottom end of the toggle rod 23 will be inserted into the toggle hole 210. When the cylinder 3 continues to push the connecting seat 4 to move downward, the bottom of the toggle rod 23 will contact the inclined surface of the inclined surface block 212, so that the toggle rod 23 will rotate with the center line of the shaft 22 as the axis. Since the toggle rod 23 is first inserted into the toggle hole 210 and then rotated, the toggle rod 23 will pull the pull rod 29 through the toggle hole 210, and the pull rod 29 will slide along the positioning block 211. When the toggle rod 23 is rotated to no longer conflict with the inclined block 212, the slide plate 27 will drive the clamped profile to move into the bending groove 6, and as the cylinder 3 drives the connecting seat 4 and the connecting seat 4 drives the bending pressure block 5 to extrude and bend the profile in the bending groove 6, when the bending is completed, the bolt 215 is loosened to remove the bent profile, and the torsion spring 25 will pull back the toggle rod 23 when the cylinder 3 is raised, and the spring 28 will push the slide plate 27 to reset. During the bending process, there is no need to manually hold the profile into the bending machine to prevent the bending machine from pinching the hands of the staff. In addition, through the fixed distance of the pull bar 29 and the toggle rod 23, each group of profiles has the same distance and position when bending, thereby making mass production more accurate.
[0025] When the profile is moved by the slide plate 27 and the clamp plate 213, the edge of the profile will hit the inclined surface of the resistance block 218, causing the resistance block 218 to shrink along the cross bar 217. When the profile is completely located on the inner side of the resistance block 218, the spring 219 will push the resistance block 218 to provide auxiliary support on both sides of the profile and correct the position to prevent the profile from tilting and causing the bending position to shift.

Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
