At the same time, the first slider 24 and the second slider 25 drive the first clamping plate 12 and the second clamping plate 13 to squeeze the clamping steel ball 14. After extrusion, the clamping steel ball 14 clamps the bar through the annular groove 11.

[0033] Example 3

[0034] Furthermore, on the basis of Example 2, the first transmission mechanism includes a motor mounting frame 15 arranged on one side of the material receiving block 3, a dual-axis motor 16 is arranged on the motor mounting frame 15, the two output shafts of the dual-axis motor 16 are arranged vertically, and a first gear 17 engaged with the first rack 5 is arranged on the downward output shaft.

At the same time, the first bevel gear 19 on the upward output shaft drives the second bevel gear 20, the first rotating shaft 18, the second gear 26, the clamping gear 37 and the second rotating shaft 22 to start rotating. When the second rotating shaft 22 starts to rotate, the screws 23 at both ends of it start to rotate, so the first slider 24 and the second slider 25 threadedly connected to the two screws 23 move toward each other. At the same time, the first slider 24 and the second slider 25 drive the first clamping plate 12 and the second clamping plate 13 to squeeze the clamping steel ball 14. After squeezing, the clamping steel ball 14 clamps the bar through the annular groove 11.

When the material is cut and new material needs to be clamped, the dual-axis motor 16 starts to reverse, and then the first gear 17 rotates to drive the first rack 5 meshing with it to drive the material receiving trough 4 to move in the direction away from the bar clamping mechanism. At the same time, under the action of the first bevel gear 19, the second bevel gear 20, the first rotating shaft 18, the second gear 26, the clamping gear 37 and the second rotating shaft 22, when the second rotating shaft 22 starts to rotate, the screws 23 at both ends rotate in the opposite direction, so the first slider 24 and the second slider 25 threadedly connected to the two screws 23 move away from each other. The first slider 24 and the second slider 25 drive the first clamping plate 12 and the second clamping plate 13 to move away from each other, so that the old bar material is loosened and falls down. At the same time, when the receiving trough 4 moves in the direction away from the bar clamping mechanism, the second rack 8 thereon drives the third gear 30, the fourth gear 32, the fourth rotating shaft 31, the third bevel gear 33, the fourth bevel gear 34 and the support shaft 7 to rotate.
