The length extension direction of the screw rod 2 is parallel to the length extension direction of the metal pipe 5 and is parallel to the feeding direction of the metal pipe 5. The nut connecting piece 4 moves linearly along the length extending direction of the screw rod 2 along with the rotation of the screw rod 2.
The conveying mechanism further comprises a jaw assembly 6 which is arranged on the nut connecting piece 4 and can rotate around the self axial lead direction and is used for clamping the metal pipe 5, and a second driving motor 7 which is arranged on the nut connecting piece 4 and is used for driving the jaw assembly 6 to rotate around the self axial lead direction. The jaw assembly 6 extends coaxially with the metal pipe 5, and the second driving motor 7 is a servo motor and is used for driving the metal pipe 5 to intermittently rotate through a set angle at a set angular speed.
The claw assembly 6 is provided with a sleeve 8 for sleeving the metal pipe 5, the sleeve 8 is provided with a gap along the axial direction, the gap is used for disconnecting the sleeve 8 along the radial direction of the sleeve 8, and the sleeve 8 disconnected along the gap is rectangular after being flattened. Through setting up this sleeve pipe 8, make 5 surfaces of metal tubular product be difficult for being pressed from both sides by the chuck subassembly 6 and hinder, through setting up the sleeve pipe 8 that has this clearance, make metal tubular product 5 can be more easy penetrate this sleeve pipe 8 in. Meanwhile, for the metal pipes 5 with different diameters, the sleeve 8 can be sleeved, and the difference is that the width of the gap is different after the metal pipes 5 with different diameters are sleeved. Obviously, the sleeve 8 should have a certain elasticity.
The nut connecting member 4 includes a connecting base plate 41, a nut sleeve (not shown) disposed on a lower surface of the connecting base plate 41 for receiving the lead screw 2, a connecting riser 42 disposed on an upper surface of the connecting base plate 41 for connecting the jaw assembly 6, and a second driving motor 7 disposed on an upper surface of the connecting base plate 41.
