Abstract
The utility model relates to a long-core-rod and compound-die pipe drawing device. The pipe drawing device mainly comprises a compound die, a drawing machine seat, a seamless steel pipe to be drawn, a drawing machine, a drawing clamping device and a cylindrical long-core rod. The long-core-rod and compound-die pipe drawing device is characterized in that the compound die is fixed on the drawing machine seat; the headed end of the seamless steel pipe to be drawn penetrates through an inner hole of the compound die, then is clamped by the drawing clamping device on the drawing machine, and simultaneously penetrates into the cylindrical long-core rod till the headed end part of the seamless steel pipe to be drawn; and under the traction action of the drawing machine, the seamless steel pipe to be drawn and the cylindrical long-core rod penetrating into the inner wall thereof move forwards in a synchronous manner, and in the process of moving forwards of the seamless steel pipe to be drawn, the diameter reduction and the wall reduction are implemented under the common action of the compound die and the cylindrical long-core rod.
Description
Affiliated technical field
The utility model relates to a kind of long plug compound die pipe drawing device, belongs 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 utility model provides a kind of long plug compound die pipe drawing device; Adopt this device to reduce about 10% than its draw power of single mode tube drawing, power consumption can be practiced thrift about 10%, and production efficiency improves about 80%.
The utility model solves the technical scheme that its technical problem adopted: 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 beneficial effect of the utility model is: adopt long plug compound die tube drawing to become the tube drawing of the tube drawing of two passages of original single mode into a passage of present compound die, shortened the production cycle, practiced thrift the energy, improved production efficiency.

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.
