[0029] Embodiment 2

[0030] The main difference from Embodiment 1 is that:

[0031] A multi-station metal profile punching line. In the positioning mechanism 3, it includes a support frame 31 installed on the top of the punching table 2. A positioning motor 32 is fixedly connected to the top of the support frame 31. The positioning motor 32 is a three-phase asynchronous motor and is connected to the external circuit through wires. One end of the output shaft of the positioning motor 32 is fixedly connected with a control bevel gear 33 through a coupling. The surface of the control bevel gear 33 makes the moving plate 34 slide through the transmission assembly 7. A positioning roller 35 is rotatably connected inside the moving plate 34. The transmission assembly 7 includes a transmission bevel gear 71 rotatably installed on the top of the support frame 31 and a limiting rod 72 installed inside the moving plate 34. The surface of the transmission bevel gear 71 meshes with the surface of the control bevel gear 33. A lead screw 73 is threadedly connected inside the transmission bevel gear 71. The bottom end of the lead screw 73 is rotatably connected to the top of the moving plate 34. The surface of the limiting rod 72 is slidably connected inside the support frame 31. On the left side of the top of the punching table 2, there are symmetrically arranged limiting devices 8. The limiting device 8 includes a cylinder, a limiting frame and a limiting roller. The cylinder drives the limiting frame to move. The limiting roller is rotatably installed inside the limiting frame. The surface of the support frame 31 is provided with a punching device 9. There are three groups of punching devices 9, all of which include a cylinder and a punching head. Side punching structures are arranged on the front side and the rear side of the support frame 31 for punching the two side surfaces of the C-shaped steel plate. A top punching structure is arranged on the top of the support frame 31 for punching the top surface of the C-shaped steel plate. By setting the positioning mechanism 3 and cooperating with the guide rollers installed on the top of the workbench, the clamping and positioning of the workpiece are realized, keeping the workpiece from shifting during the punching operation, improving the stability of the workpiece, and further improving the punching quality. At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0032] During operation, first, one end of the C-shaped steel workpiece to be punched by the craftsman is placed on the top of the bearing plate 414, and the other end is placed on the surface of the guiding rollers installed on the top of the conveying table 1 and the punching table 2. The clamping and fixing of the workpiece are achieved through the clamping assembly inside the conveying plate 413. By starting the driving and positioning motor 32, the control bevel gear 33 is driven to rotate. The rotation of the control bevel gear 33 causes the transmission bevel gear 71 to rotate. The rotation of the transmission bevel gear 71 causes the lead screw 73, the limit rod 72, the moving plate 34, and the positioning roller 35 to slide downward synchronously. The workpiece is positioned by the positioning roller 35. Then, by starting the driving motor 421, the driving rod 422, the arc-shaped block 423, and the driving block are driven to rotate synchronously, so that the driving block slides on the inner surface of the sliding groove 5, thereby driving the rotating disk 415, the rotating rod 411, and the conveyor belt 412 to rotate synchronously. When the driving block slides out of the sliding groove 5, at this time, the outside of the arc-shaped block 423 slides inside the arc-shaped plate 6, and at this time, the conveyor belt 412 remains stationary. Driven continuously by the driving rod 422, the arc-shaped block 423, and the driving block, the conveyor belt 412, the conveying plate 413, and the workpiece fixed on the top of the conveying plate 413 move intermittently to the left synchronously. Then, the punching operation is performed on three surfaces of the C-shaped steel workpiece through the provided punching device 9.
