A bidirectional lead screw module 4 is provided under each slotted hole 3. A movable frame 5 is slidably connected to both sides of each bidirectional lead screw module 4. The upper side of each movable frame 5 passes through the slotted hole 3 and extends to the upper side of the frame 1. A limiting roller 6 is provided on the upper side of the movable frame 5. A 1 / 2-shaped limiting roller mounting frame is provided on the upper side of the movable frame 5. Specifically, the openings of the limiting roller mounting frames on both sides of the slotted hole 3 are arranged opposite to each other. The limiting roller 6 is rotatably mounted on the limiting roller mounting frame.

Electric push rods 11 are provided on the upper horizontal plates of the portal frame 7 on both sides of the hydraulic push rod 8. The output end of the electric push rod 11 passes through the portal frame 7 and is connected to a circular frame 12. Clamping components are provided on both the front and rear sides of the circular frame 12. A knife hole 13 corresponding to the cutting scissors 10 is opened on the upper side of the frame 1.

[0020] The clamping assembly includes a vertical plate 14 connected to the front or rear side of the clip 12. A pressure block 15 is provided on the lower side of the vertical plate 14. L-shaped adjusting brackets 16 are inserted into both sides of the pressure block 15, and the L-shaped adjusting brackets on both sides are inserted into each other. A connecting bolt 17 is provided at the insertion point between the L-shaped adjusting bracket 16 and the pressure block 15. The cutting shears 10 pass through the middle hole of the clip 12.

[0021] After the cold-rolled strip steel is processed, it needs to be cut. The operator can connect the strip steel to the feeding device 2. The feeding device 2 mainly consists of a frame, two feeding rollers, two gears and a motor. The connection method between the above parts is well known to those in the art and will not be described in detail. When the motor is running, it can drive the two feeding rollers to rotate in opposite directions, thereby feeding the cold-rolled strip steel.
