[0033] Example 2
[0034] See also Figure 2 , Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that:
[0035] A servo motor 16 is fixedly connected to one end of the first guide rail box 6 and the front end of the second guide rail box 13, and a threaded column 17 is provided in the inner cavity of the first guide rail box 6 and the inner cavity of the second guide rail box 13. One end of the threaded column 17 is fixedly connected to the output end of the servo motor 16, and the threaded column 17 is fixedly connected to the bearing body at one end away from the servo motor 16; a sliding block 18 is fixedly connected to the bottom surface of the moving plate 7 and the top surface of the moving plate 14, and the sliding block 18 is threadedly connected to the outer surface of the threaded column 17, and the top surface of the first guide rail box 6 is fixedly connected to the second guide rail box 13. The bottom surface of the guide rail box 13 is provided with a slide groove that matches the structural size of the sliding block 18; that is, the two threaded columns 17 are movably connected to the first guide rail box 6 and the second guide rail box 13 through the bearing body, respectively, to ensure that under the drive of the two servo motors 16, the two threaded columns 17 can rotate in the inner cavity of the first guide rail box 6 and the second guide rail box 13 respectively. When the servo motor 16 drives the rotation of the threaded column 17, the sliding block 18 is threadedly connected to the outer surface of the threaded column 17, which can drive the movement of the sliding block 18.
[0036] It should be noted that: through the personnel in this field, all the electrical components in this case, the vacuum pump 4, the first reduction motor 8, the clamping electric push rod 9, the second reduction motor 10, the servo motor 16, the upper and lower electric push rods 19 and the left and right electric push rods 20, are connected to their corresponding power supplies through wires, and a suitable controller, such as a PLC controller or a single-chip microcomputer, should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the working order. The detailed connection means are well known in the field. The following mainly introduces the working principle and process, and no longer explains the electrical control.
[0037] The working principle and use process of the utility model are as follows: when in use, after the cold-rolled steel strip is clamped, the servo motor 16 at one end of the first guide rail box 6 is controlled to start, driving the rotation of the threaded column 17 in the inner cavity of the first guide rail box 6. Since the sliding block 18 at the bottom of the moving plate 7 is threadedly connected to the outer surface of the threaded column 17, at this time, as the threaded column 17 rotates, the moving plate 7 assembly moves away from the fixed plate 5 to straighten the cold-rolled steel strip. Further, the extension and contraction of the left and right electric push rods 20 are controlled to adjust the left and right positions of the cutting machine. Fine adjustment is performed, and then the extension of the upper and lower electric push rods 19 is controlled to control the fall of the cutting machine, and then the servo motor 16 at the front end of the second guide rail box 13 is started. At this time, the servo motor 16 drives the threaded column 17 inside the second guide rail box 13 to rotate, and the movable plate 14 and the sliding block 18 move in the direction of the second guide rail box 13 to shear the cold-rolled steel strip. Further, the start of the vacuum pump 4 is controlled. At this time, the dust hood 15 will generate suction to absorb the sheared iron filings and put them into the dust collecting box 2 for storage.
