5) piston mechanism promotes to have contact with and stretches out, have contact with catch on the drawing jaw after, the jaw of drawing jaw opens (tube head disengaging jaw), the piston mechanism withdrawal will be had contact with the drawing jaw and be retracted initial position;
6) last, drawing leader mechanism removes in advance, the closed metal pipe material of having been pulled out by the drawing jaw that clamps of the first drawing chain and the second drawing chain, and pre-drawing process is finished.
After pre-drawing was finished, sprocket rotation drove the first drawing chain and the operation of the second drawing chain and by frictional force pulling metal pipe material.Need not that one section linear material of termination prolongs material before material, whole pre-drawing process has realized automatically and the continuous drawing course of work without manual operation.
As a further improvement on the present invention, the jaw place of described drawing jaw is provided with the first pincers portion and the second pincers portion, all is provided with the cylinder that drives them and move in the described first pincers portion and the second pincers portion.When being in above-mentioned pre-drawing process the 3rd) during step, they move the air cylinder driven in the first pincers portion and the second pincers portion towards the other side, thus make the closed tube head that clamps of jaw; When being in above-mentioned pre-drawing process the 5th) during step, they deviate from the air cylinder driven in the first pincers portion and the second pincers portion the other side and move, and make jaw open, and tube head breaks away from jaw.
Generally speaking, compared with prior art, continuous draw-off gear for metal linear material of the present invention, set up a pre-drawing leader mechanism, need not that one section linear material of termination prolongs material before material, whole pre-drawing process has realized automatic continuous drawing work without manual operation.
