Abstract
The invention relates to a long core rod composite die pipe drawing device, which comprises a composite die, a drawing machine base, a seamless steel pipe to be drawn, a drawing machine, a drawing holder and a cylindrical long core rod; and is characterized in that the composite die is fixed on the drawing machine base, a drive head of the seamless steel pipe to be drawn passes through an inner aperture of the composite die, and is clamped by the drawing holder on the drawing machine and passes through the cylindrical long core rod to the end part of the drive head of the seamless steel pipe to be drawn; the seamless steel pipe to be drawn is synchronously proceed with the cylindrical long core rod which passes through the inner wall of the seamless steel pipe under the traction action of the drawing machine, and the diameter reduction and wall reduction are carried out under the coaction of the composite die and the cylindrical long core rod in the proceeding process of the seamless steel pipe to be drawn.
Description
Affiliated technical field
The present invention relates to a kind of long plug compound die pipe drawing device, belong to metal rolled technical field.
Background technology
Seamless steel tube production cold-drawn device adopts long plug single mode tube drawing mostly at present, and the single mode tube drawing needs the multi-pass tube drawing just can obtain the qualified production tube of size, and the production cycle is long, and energy resource consumption is big, and production cost is high.
Summary of the invention
In order to solve the above-mentioned drawback of the long plug single mode pipe drawing device of tradition, the present invention provides a kind of long plug compound die pipe drawing device, adopts this device to reduce about 10% than its draw power of single mode tube drawing, and power consumption can be practiced thrift about 10%, and production efficiency improves about 80%.
The technical solution adopted for the present invention to solve the technical problems is: compound die is fixed on the drawbench bed; Treat that its end of taking the lead of drawing seamless steel tubes at first passes the compound die endoporus; Then clamped and penetrate cylindrical long plug simultaneously to the end of taking the lead of treating drawing seamless steel tubes by the puller gripper on the drawbench; Treat under the action of traction of drawbench that then drawing seamless steel tubes and the cylindrical long plug that penetrates its inwall move ahead synchronously, treat that drawing seamless steel tubes implements tube reducing and subtract wall in the process that moves ahead under the acting in conjunction of compound die and cylindrical long plug.
The invention has the beneficial effects as follows: adopt long plug compound die tube drawing to become the tube drawing of the tube drawing of two passages of original single mode, shortened the production cycle, practiced thrift the energy, improved production efficiency into a passage of present compound die.

1. treat drawing seamless steel tubes among the figure, 2. drawbench bed, 3. compound die, 4. puller gripper, 5. drawbench, 6. cylindrical long plug, 7. large scale tube reducing sizing endless belt, 8 small size tube reducing sizing endless belt.
The specific embodiment
In Fig. 1, Fig. 2, Fig. 3, Fig. 4; Compound die 3 is fixed on the drawbench bed 2; Treat that drawing seamless steel tubes 1 its end of taking the lead at first passes compound die 3 endoporus; Then clamped and penetrate cylindrical long plug 6 simultaneously to the end of taking the lead of treating drawing seamless steel tubes 1 by the puller gripper on the drawbench 54; Treat under the action of traction of drawbench 5 that then drawing seamless steel tubes 1 and the cylindrical long plug 6 that penetrates its inwall move ahead synchronously, treat that drawing seamless steel tubes 1 implements tube reducing down and subtract wall in the acting in conjunction of compound die 3 and cylindrical long plug 6 in the process that moves ahead.The concrete structure of compound die 3 is: keep traditional single withdrawing pattern thickness constant, its effect is the crop loss that does not increase in the steel pipe drawing process; The withdrawing pattern inner hole structure re-designs; Design and produce the large scale tube reducing sizing endless belt 7 and small size tube reducing sizing endless belt 8 of two groups of descending arrangements of diameter dimension side by side at the axis direction of compound die 3 endoporus; During the drawing operation; Treat that drawing seamless steel tubes 1 at first carries out the tube reducing sizing first time through large scale tube reducing sizing endless belt 7, then carries out the tube reducing sizing second time through small size tube reducing sizing endless belt 8 again; The concrete structure of cylindrical long plug 6 is: profile is an elongated cylinder; Cone structure is processed in a termination portion that penetrates in the steel pipe; The other end is connected with the plug coaster, and its length and diameter are confirmed by length and the diameter of treating drawing seamless steel tubes 1 and finished product seamless steel pipe.
