Drawing is one of the main production modes of pipes, profiles, bars and wires. Before the drawing machine draws, the steel tube 4 needs to be shrunk, as shown in fig. 1, firstly, the steel tube 4 at one end without shrinking is led into the traction mechanism 3, then the steel tube 4 on the traction mechanism 3 is pushed into the die 5 by the first conveying device 2 in the base 1, one end of the shrinking head of the steel tube 4 passes through the die and moves into the clamping seat 6, the clamping seat 6 is used for clamping and fixing the steel tube 4, and finally the second conveying device 7 is used for moving the clamping seat 6, so that the part of the steel tube 4 without shrinking head is extruded with the die 5, and the preset shape (outer diameter, inner diameter and wall thickness) which is the same as the steel tube 4 after shrinking head is obtained, thereby realizing drawing.
In the prior art, in order to improve the drawing efficiency, a manner of improving the moving speed of the clamping seat 6 is generally adopted to perform quick drawing, in this process, the length of the steel pipe to be shrunk is limited, the contact area between the clamping seat 6 and the steel pipe 4 after shrinking is also limited, so that the higher the drawing speed is, the larger the transverse force between the clamping seat 6 and the steel pipe 4 is, and the steel pipe 4 is extremely easy to wear. If the mode of lengthening the length of the shrinking head is adopted, on one hand, the shrinking head equipment does not support the long shrinking head stroke, and on the other hand, the shrinking head working efficiency of the shrinking head equipment is low and is far lower than that of the drawing working efficiency of the conventional speed.

In the technical scheme, in the embodiment of the invention, the telescopic device is started after the head shrinking part of the steel pipe is propped against the propping piece, the telescopic rod pulls the rotary drum to drive the rotary drum to slide, the corner piece is stressed to rotate, and the clamping piece is pushed to clamp the steel pipe. And secondly, when the telescopic rod pulls the rotary drum, the connecting piece on the telescopic rod applies force to slide in the annular groove in the rotary drum, so that the top piece on the rotary drum rotatably jacks up the rack. And then the rack drives the stirring assembly to rotate, and the stirring unit stirs the auxiliary clamping piece, so that the auxiliary clamping piece slowly moves towards the surface of the steel pipe. Then when the auxiliary clamping piece slowly moves towards the surface of the steel pipe, the drawing machine starts the second conveying device to drive the drawing clamping seat to move so as to draw the steel pipe. Finally, when the drawing clamp seat moves, the connecting piece on the telescopic rod continuously applies force to slide in the annular groove in the rotary drum, the top piece continuously rotates to jack up the rack, the stirring unit continuously stirs the auxiliary clamping piece, and the auxiliary clamping piece clamps the steel pipe (the steel pipe drawing part becomes longer in the steel pipe drawing process before the speed of the second conveying device is increased), so that a clamping space is provided for the auxiliary clamping piece to clamp the steel pipe).

a storage space accommodating the telescopic rod;
the annular groove is connected with the connecting piece;
a top piece connected with the outer diameter of the rotary drum,
a rack in an opposite direction to the top piece;
the stirring assembly is meshed with the rack;
the auxiliary clamping piece is connected with the stirring unit;
the toggle assembly includes:
a gear unit engaged with the rack;
the force application unit is connected with the gear unit;
the stirring unit is connected with the force application unit;
the drawing holder further comprises a half ring groove, and the auxiliary clamping piece comprises:
and the semi-ring member is placed in the semi-ring groove.
2. The drawing machine cartridge of claim 1, wherein the drawing cartridge further comprises:
and the clamping piece is positioned in the sliding groove.
3. The drawing machine holder of claim 1, wherein the end of the corner piece connected to the elongated slot is spherical.
4. The extractor holder of claim 1, wherein the opposed end surfaces of the clamping member have abutments.
5. The drawing machine cartridge of claim 1, wherein the drum and the slider are connected with bearings.
6. The extractor holder of claim 1, wherein the annular groove is sloped.
7. The drawing machine holder of claim 1, wherein the top piece is conical, the apexes of the top piece face away from each other, and the apexes of the top piece are in the same horizontal direction.
8. A clamping method of a clamping seat, which is applied to the clamping seat of a drawing machine according to any one of the claims 1 to 7, and comprises the following steps:
after the shrinkage head part of the steel pipe abuts against the abutting piece, the telescopic device is started, the telescopic rod pulls the rotary drum to drive the rotary drum to slide, the corner piece is stressed to rotate, and the clamping piece is pushed to clamp the steel pipe;
the telescopic rod pulls the rotary drum, meanwhile, the connecting piece on the telescopic rod applies force to slide in the annular groove in the rotary drum, and the aim of rotating the rotary drum is achieved under the condition that the clamping force of the clamping piece is ensured to be maintained, so that the top piece on the rotary drum jacks up the rack;
the gear unit drives the force application unit to apply force to the stirring unit, and then the stirring unit stirs the semi-ring component of the auxiliary clamping piece, and the semi-ring component moves along the semi-ring groove, so that the auxiliary clamping piece slowly moves towards the surface of the steel pipe;
drawing displacement, when the auxiliary clamping piece slowly moves towards the surface of the steel pipe, the drawing machine starts the second conveying device to drive the drawing clamping seat to move so as to draw the steel pipe;
auxiliary clamping, when drawing the holder and removing, connecting piece on the telescopic link is in continuous application of force slip in the ring channel in the rotary drum, conical top piece continuously jack-up the rack, stir the unit and continuously stir auxiliary clamping piece, make before second conveyer speed improves auxiliary clamping piece grips the steel pipe.
