[0004] The device uses an electric push rod and a mounting rod to squeeze the workpiece to complete the bending of the workpiece. However, during the squeezing and bending process, the internal stress of the steel bar will change as the steel bar bends. The device lacks a structure to guide the steel bar during the bending process. The steel bar may deviate or even pop out due to the stress during the bending process, posing a safety hazard. Utility Model Content

[0023] like Figures 1-4 As shown, the utility model provides a technical solution: a bending machine with a guiding mechanism, comprising a machine body 1, a hydraulic cylinder 2 is fixedly installed on the inner wall of the machine body 1, a bending rod 3 is fixedly installed on the piston end of the hydraulic cylinder 2, and a support rod 4 is fixedly installed on the side wall of the machine body 1. The steel bars are placed on the two sets of support rods 4, and then the hydraulic cylinder 2 is started to drive the bending rod 3 to move downward, and the bending rod 3 is used to move downward to squeeze the steel bars and bend the steel bars. A guiding mechanism 5 is provided on the machine body 1 to prevent the steel bars from running away. By setting the guiding mechanism 5, the steel bars can always fit into the side wall of the machine body 1 during the bending process, thereby preventing the steel bars from bending or popping out due to stress during the bending process. An auxiliary mechanism 6 is provided on the guide mechanism 5. By setting the auxiliary mechanism 6, it is convenient for the staff to control the bending angle of the steel bars.

[0024] The above-mentioned guide mechanism 5 includes a threaded rod 51, a positioning plate 52, a connecting rod 53, a handle 54, and a threaded block 55; one end of the threaded rod 51 is rotatably connected to the outer wall of the body 1, and the other end of the threaded rod 51 is fixedly installed with a handle 54. The outer wall of the threaded rod 51 is threadedly connected with a threaded block 55. The threaded rod 51 is rotated by the handle 54, and the threaded block 55 is driven upward by the rotation of the threaded rod 51. The positioning plate 52 is slidably connected to the outer wall of the support rod 4. The support rod 4 is provided with two groups. The two groups of support rods 4 are mirror-imaged and arranged on the side wall of the body 1 with the bending rod 3 as the central axis. The outer walls of the two groups of support rods 4 are The sliding connection is provided with a positioning plate 52. The positioning plates 52 on the two sets of support rods 4 can be used to limit the steel bars so that the steel bars always fit into the side wall of the machine body 1 during the bending process, thereby preventing the steel bars from bending or popping out due to stress during the bending process. One end of the connecting rod 53 is hinged to the outer wall of the positioning plate 52, and the other end of the connecting rod 53 is hinged to the side wall of the threaded block 55. When the threaded block 55 moves upward, it squeezes the connecting rod 53, thereby causing the connecting rod 53 to squeeze the positioning plate 52, causing the positioning plate 52 to slide on the outer wall of the support rod 4 and gradually approach the side wall of the machine body 1.

[0025] The above-mentioned auxiliary mechanism 6 includes a slider 61, a limit rod 62, a pointer 63, an angle ruler 64, and a spring sheet 65; the slider 61 is slidably connected to the inner wall of the positioning plate 52, and a limit rod 62 is fixedly installed on one side of the slider 61, and a pointer 63 is fixedly installed on the other side of the slider 61. During the bending process, the steel bar will squeeze the limit rod 62 downward, so that the limit rod 62 drives the slider 61 to slide downward on the inner wall of the positioning plate 52, and causes the slider 61 to compress the spring sheet 65. The outer wall of the positioning plate 52 is fixedly installed with an angle ruler 64. The pointer 63 and the angle ruler 64 can be used to observe the moving angle of the slider 61, so that the moving angle of the limit rod 62 can be known, so that the bending angle of the steel bar at this time can be judged. The outer wall of the slider 61 is fixedly installed with a spring sheet 65, and the end of the spring sheet 65 away from the slider 61 is fixedly installed on the inner wall of the positioning plate 52. The elasticity of the spring sheet 65 can be used to push the slider 61 to slide and reset.

[0026] Working principle: first place the steel bar on the two sets of support rods 4, then rotate the threaded rod 51 through the handle 54, and the rotation of the threaded rod 51 drives the threaded block 55 to move upward. At this time, the threaded block 55 will squeeze the connecting rod 53, so that the connecting rod 53 squeezes the positioning plate 52, so that the positioning plate 52 slides on the outer wall of the support rod 4 and gradually approaches the side wall of the machine body 1 until the positioning plate 52 presses the steel bar against the side wall of the machine body 1, and then start the hydraulic cylinder 2 to drive the bending rod 3 to move downward, and use the bending rod 3 to move downward to squeeze the steel bar to bend the steel bar. At the same time, the positioning plates 52 on the two sets of support rods 4 can limit the steel bar, so that the steel bar always fits into the side wall of the machine body 1 during the bending process, thereby preventing the steel bar from bending or popping out due to stress during the bending process, so that the staff can perform bending processing under safe working conditions and avoid the occurrence of safety accidents.

[0027] During the bending process, the steel bar will squeeze the limit rod 62 downward, so that the limit rod 62 drives the slider 61 to slide downward on the inner wall of the positioning plate 52, and the slider 61 compresses the spring sheet 65. At the same time, the slider 61 will drive the pointer 63 to move synchronously with the outer wall of the angle ruler 64. At this time, the pointer 63 and the angle ruler 64 can be used to observe the moving angle of the slider 61, so that the moving angle of the limit rod 62 can be known, and the bending angle of the steel bar at this time can be judged, which is convenient for the staff to accurately control the bending angle of the steel bar.

[0028] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
