Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0025] like Figure 1 - Figure 4 As shown, this application provides a translational pushing mechanism, including a pushing table 1; and further including;
[0026] Specifically, such as Figure 2 As shown, a moving component 2 is provided on the top of the pusher table 1. The moving component 2 is used to move the wire. The moving component 2 includes a first moving wheel 201, which is disposed on the inner wall of the pusher table 1. A second moving wheel 202 is disposed above the first moving wheel 201. The first moving wheel 201 and the second moving wheel 202 rotate in opposite directions. By providing the moving component 2 on the top of the pusher table 1, and by simultaneously driving the first moving wheel 201 and the second moving wheel 202 on the moving component 2 to rotate in opposite directions, the wire can be driven to move towards the cold rolling mechanism at a uniform speed for processing, thereby improving the stability and efficiency of its processing.
[0027] The top of the pusher platform 1 is provided with a connecting frame 207, and the second moving wheel 202 is rotatably connected to the inner wall of the connecting frame 207. The side walls of the pusher platform 1 and the connecting frame 207 are provided with two sets of motor drivers, and the output shafts of the motors are fixedly connected to the first shaft 2011 and the second moving wheel 202 respectively. The motor can drive the second moving wheel 202 to rotate clockwise.
[0028] Specifically, such as Figure 3As shown, the first moving wheel 201 is fixedly connected to the two sides of the first shaft 2011. The first shaft 2011 is rotatably connected to the inner wall of the pusher table 1. The inner wall of the pusher table 1 is rotatably connected to the passive rod 2031. The outer wall of the passive rod 2031 is fixedly connected to the drive wheel 203. The first shaft 2011 and the first moving wheel 201 can be driven to rotate counterclockwise by another set of motors.
[0029] A drive wheel 204 is fixedly connected to the outer peripheral wall of the first shaft 2011, and a driven wheel 205 is fixedly connected to the outer peripheral wall of the driven shaft 2031. A belt 206 is rotatably connected to the outer walls of the drive wheel 204 and the driven wheel 205. The drive wheel 204 can be driven to rotate through the inner wall of the first shaft 2011. At the same time, the rotation of the drive wheel 204 can drive the driven wheel 205 and the drive wheel 203 to rotate through the belt 206, which facilitates further movement and conveying of the wire.
[0030] The side wall of the pusher table 1 is threaded with a lead screw 208. The end of the lead screw 208 is rotatably connected to a limit member 2082. The side wall of the limit member 2082 is fixedly connected with a stabilizing rod 2081. The stabilizing rod 2081 passes through both sides of the pusher table 1.

[0034] The specific solution is as follows: First, based on the thickness of the wire, the hydraulic cylinder 303 drives the movable plate 302 to move upward. At this time, the movable plate 302 can drive the four sets of connecting rods 301 and connecting frame 207 to move upward and adjust until the distance between the second moving wheel 202 and the first moving wheel 201 is suitable for the thickness of the wire. At the same time, it drives two sets of motors. Through the drive of the motors, the second moving wheel 202 and the first moving wheel 201 can be driven to rotate in opposite directions.
