[0024] Secondly, the bending plate 4 includes a first straight plate arranged vertically, a second straight plate arranged horizontally, and a curved plate with a certain curvature, wherein the first straight plate, the second straight plate and the curved plate are connected to each other, wherein the distance between the upper end surface of the first straight plate and the lower end surface of the second straight plate is greater than the distance between the upper and lower end surfaces of the clamping plate 5, and the upper end surface of the second straight plate is spaced below the lower end surface of the mounting seat 8, and at the same time, the curvature of the curved plate is 80°-110°. In this embodiment, the curvature of the curved plate is selected to be 93°, which has the best bending effect on the wire.

[0025] It is worth noting that in this embodiment, the power assembly 11 includes a second telescopic shaft 114, a sliding block 113, a guide rod 112 and a movable groove 111; the movable groove 111 is opened on the right end surface of the bending plate 4, and the guide rod 112 is fixedly arranged inside the movable groove 111, and the sliding block 113 is sleeved on the rod body of the guide rod 112, and the sliding block 113 is slidably arranged in the movable groove 111, and the end of the sliding block 113 away from the movable groove 111 extends into the external space and is fixedly connected to the left end surface of the clamping plate 5, and in addition, the left side of the upper end surface of the sliding block 113 is fixedly provided with a second telescopic shaft 114, and the upper end of the second telescopic shaft 114 is connected to a pipeline;

[0026] In this embodiment, a two-position three-way valve (not shown in the figure) is fixedly provided at the driving end of the cylinder, and the output ports of the two-position three-way valve are respectively connected to the first telescopic shaft and the pipeline. During the operation of the equipment, the step-by-step and synchronous movement of the clamping plate 5 and the bending plate 4 are controlled by adjusting the working position of the two-position three-way valve.

[0027] refer to Figure 4 It can be seen that a wire bending machine also includes an auxiliary component 7, which includes two sliding blocks 72, a convex groove 73, a limit block 74 and a fixed plate 71; the left end face of the fixed plate 71 is fixedly arranged on the right end face of the mounting plate 6, and the upper end face of the fixed plate 71 is provided with a convex groove 73, the convex part of the convex groove 73 passes through the right end face of the mounting plate 6, so that the right end face of the mounting plate 6 constitutes a two-part clamping portion, the two sliding blocks 72 are arranged on the left end face of the mounting seat 8 at intervals front and back, and the end faces of the two sliding blocks 72 away from each other are provided with clamping grooves that pass through from top to bottom, the clamping grooves and the clamping portions correspond one to one, that is, one clamping groove corresponds to one clamping portion, and the inner lower side of the convex groove 73 accommodates a limit block 74, which is used to limit the separation of the sliding block 72 and the mounting plate 6 to ensure the stability of the equipment.

[0028] Working principle of the present invention: during operation, the wire is placed in the corresponding arc groove, then, the cylinder is started, the two-position three-way valve opens the branch connected to the pipeline, and the clamping plate 5 is driven to move downward. At this time, the lower end surface of the clamping plate 5 and the upper end surface of the placement seat 3 are in contact with each other, and then, the two-position three-way valve opens the branch connected to the first telescopic shaft, driving the mounting seat 8 to move downward. At the same time, the sliding block 113 slides in the movable groove 111. As the mounting seat 8 gradually moves downward, the wire is bent under the action of the arc plate. At the same time, due to the angle of the arc plate and the arc surface in the arc groove, the bending angle is prevented from being too large and the wire is prevented from being damaged by the shear force.
