Abstract
The invention provides a short mandrel composite die tube drawing apparatus which mainly comprises a composite die, a drawbench frame, a seamless steel tube to be drawn, a drawbench, a drawing holder and a cylindrical short mandrel. The apparatus is characterized in that the composite die is fixed on the drawbench frame, the head end of the seamless steel tube to be drawn passes through an inner bore of the composite die at first, then the seamless steel tube to be drawn is clamped by the drawing holder on the drawbench and simultaneously passes into the cylindrical short mandrel to a position where a small-size tube-reducing sizing annulus of the inner bore of the composite die is located, the seamless steel tube to be drawn moves forward under drawing action of the drawbench, and tube reduction and wall reduction of the seamless steel tube to be drawn are realized during the forward movement under co-action of the inner bore of the composite die and the cylindrical short mandrel.
Description
Affiliated technical field
The present invention relates to a kind of short plug compound die pipe drawing device, belong to metal rolled technical field.
Background technology
Seamless steel tube production cold-drawn device adopts short 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 short plug single mode of tradition pipe drawing device, the present invention provides a kind of short 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 the small size tube reducing sizing endless belt position that penetrates cylindrical short core print to compound die endoporus simultaneously by the puller gripper on the drawbench; Treat under the action of traction of drawbench that then drawing seamless steel tubes moves ahead, 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 endoporus and cylindrical short core print.
The invention has the beneficial effects as follows: adopt short 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.

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 small size tube reducing sizing endless belt 9 positions that penetrate cylindrical short core print 6 to compound die 3 endoporus simultaneously by the puller gripper on the drawbench 54; Treat under the action of traction of drawbench 5 that then drawing seamless steel tubes 1 moves ahead, treat that drawing seamless steel tubes 1 implements tube reducing and subtract wall in the process that moves ahead under the acting in conjunction of compound die 3 endoporus and cylindrical short core print 6.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 8 and small size tube reducing sizing endless belt 9 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 8, then carries out the tube reducing sizing second time through small size tube reducing sizing endless belt 9 again; The concrete structure of short plug is: be made up of core bar 7 and cylindrical short core print 6 two parts, core bar 7 is elongated cylindrical, 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; Cylindrical short core print 6 is a short cylinder, and its diameter is confirmed by the diameter of finished product seamless steel pipe.
Claims (1)
1. one kind short plug compound die pipe drawing device; Mainly by compound die, drawbench bed, treat that drawing seamless steel tubes, drawbench, puller gripper, cylindrical short core print, small size tube reducing sizing endless belt form; It is characterized in that: 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 the small size tube reducing sizing endless belt position that penetrates cylindrical short core print to compound die endoporus simultaneously by the puller gripper on the drawbench.
