The front end and the rear end of the second upper guide rod 51 are respectively fixedly connected with the upper connecting plate 121 and the vertical beam 11.

The front and rear ends of the second lower guide rod 52 are respectively fixedly connected to the lower connecting plate 131 and the vertical beam 11.
As shown in fig. 9, 13 and 14, an upper push rod 61 is disposed between the upper slide block 213 and the upper connecting shaft 613, one end of the upper push rod 61 is hinged to the lower side surface of the upper slide block 213 through an upper hinge shaft 612, and an ear plate for accommodating the upper hinge shaft 612 is disposed on the lower side surface of the upper slide block 213; the other end of the upper push rod 61 is hinged to the upper connecting shaft 613. As a specific embodiment, the first limiting rod 611 is fixedly connected with the upper push rod 61 in a welding manner in the embodiment, wherein the first limiting rod 611 is fixedly arranged on the upper push rod 61, and the first limiting rod 611 is perpendicular to the upper push rod 61.

A second limit rod 63 is arranged between the free end of the lower push rod 62 and the first limit rod 611, a first sliding hole extending along the axial direction is formed in one end of the second limit rod 63, the free end of the first limit rod 611 is inserted into the first sliding hole, a second sliding hole penetrating through the second limit rod 63 along the radial direction is formed in the other end of the second limit rod 63, and the free end of the lower push rod 62 is inserted into the second sliding hole. Preferably, the first slide hole is a blind hole.
The reason for this is that the upper push rod 61 and the lower push rod 62 can twist the torsion plate 4, but cannot achieve centering twisting. Because when twisting the processing to strip shaped plate material, strip shaped plate material will pass the centre of a circle of twisting disk 4, consequently can't set up the axis of rotation in the centre of a circle department of twisting disk 4, in order to realize the centering of twisting disk and twist reverse, traditional twist reverse device generally can set up round gyro wheel in the outside of twisting disk 4 or set up the circular cavity that is used for holding twisting disk in a mounting to realize the centering of twisting disk and twist reverse (the rotation promptly). Although the rotation of the torsion disc 4 can be realized by the traditional structure, the structure is complex, the volume is large, and the torsion disc is not suitable for the design.
The device enables the upper push rod 61 and the lower push rod 62 to be in a parallel state all the time by arranging the first limiting rod 611 and the second limiting rod 63. Since the upper and lower nuts 211 and 311 move toward each other or away from each other at the same speed during use, the midpoint of the line connecting the upper and lower hinge shafts 612 and 621 is absolutely fixed. Since the upper push rod 61 and the lower push rod 62 are always in a parallel state, as can be seen from fig. 9, the figure obtained by sequentially connecting the upper hinge shaft 612, the upper connecting shaft 613, the lower hinge shaft 621, and the lower connecting shaft 622 is a parallelogram. According to the parallelogram diagonal rule, the diagonals are bisected by each other, i.e., the midpoint of the line connecting the upper connecting shaft 613 and the lower connecting shaft 622 coincides with the midpoint of the line connecting the upper hinge shaft 612 and the lower hinge shaft 621. Since the midpoint of the line connecting the upper hinge shaft 612 and the lower hinge shaft 621 is absolutely fixed, the midpoint of the line connecting the upper connecting shaft 613 and the lower connecting shaft 622 is also absolutely fixed, and the midpoint of the line connecting the upper connecting shaft 613 and the lower connecting shaft 622 is the center of the torsion plate 4. Therefore, the center of the torsion disc 4 is fixed under the action of the first limiting rod 611 and the second limiting rod 63, and the torsion disc performs centering torsion.
As shown in fig. 9, the rear ends of the upper screw rod 2 and the lower screw rod 3 extend to the rear side of the vertical beam 11 through the vertical beam 11, a transmission mechanism is arranged between the upper screw rod 2 and the lower screw rod 3 and at the rear side of the vertical beam 11, and under the action of the transmission mechanism, the upper nut 211 and the lower nut 311 move in opposite directions or move in opposite directions.
As a specific embodiment, the transmission mechanism in this embodiment includes a driving pulley 71 fixedly disposed at the rear end of the screw 2, and the driving pulley 71 is connected to a driven pulley 72 fixedly disposed at the rear end of the lower screw 3 through a timing belt 73. The rotating directions of the upper screw rod 2 and the lower screw rod 3 are opposite. The front end of the upper screw rod 2 passes through the upper connecting plate 121 and extends to the front side of the upper connecting plate 121, and the front end of the upper screw rod 2 is provided with a handle 91 for driving the upper screw rod 2 to rotate. As a specific implementation manner, in this embodiment, an insertion hole having a hexagonal cross section is disposed on the front end surface of the upper screw 2, and an insertion block matched with the insertion hole is disposed on the handle 91.
As shown in fig. 3, a fixing plate 8 is disposed on the right side of the main frame, and the fixing plate 8 is slidably connected to the main frame, and the fixing plate 8 can slide left and right relative to the main frame. The front side of the fixing plate 8 is provided with a second notch 82, and in an initial state, the projections of the second notch 82 and the first notch 41 in the longitudinal vertical plane are completely overlapped.
As a specific embodiment, as shown in fig. 3, two guide posts 81 extending to the left are respectively disposed at the upper and lower ends of the fixing plate 8, and the upper cross beam 12 and the lower cross beam 13 are respectively provided with through holes matching with the guide posts 81.
For the design of the driving assembly, it is easy for the designer to articulate the upper push rod 61 directly with the upper nut 211 and the lower push rod 62 directly with the lower nut 311. However, for the present solution, the upper screw 2 is connected to the lower screw 3 through the transmission mechanism, and although theoretically, the upper screw 2 and the lower screw 3 rotate synchronously, due to the machining error of the transmission mechanism and the machining error of the screw itself, the problem that the upper screw 2 and the lower screw 3 do not start to rotate at the same time often occurs. For example, the upper screw 2 rotates first, and the rotation of the lower screw 3 lags behind the upper screw 2 for a certain time due to the existence of the transmission gap of the transmission mechanism. However, when the upper screw 2 rotates, the upper push rod 61 drives the torsion disc 4 to rotate, the torsion disc 4 rotates to drive the lower push rod 62 to move, and the lower push rod 62 moves to drive the lower nut 311 to move in the front-back direction. Due to the self-locking effect of the threads, the lower screw nut 311 cannot drive the lower screw rod 3 to rotate, and therefore the problem of blocking can occur. The solution to this problem is to improve the machining accuracy so as to ensure strict synchronization between the upper screw 2 and the lower screw 3, but this is not only difficult to ensure, but also increases the machining cost. By arranging the slider on one side of the nut and arranging the spring 92 between the slider and the nut, even if the rotation of the lower screw rod 3 is delayed to a certain extent relative to the upper screw rod 2, the upper screw rod 211 cannot be locked, and the distance moved first can be absorbed by the spring 92.
