Abstract
The utility model discloses a spherical core-head composite mould pipe drawing device, mainly consisting of a composite mould, a drawing machine seat, a pulling seamless steel pipe, a drawing machine, a drawing clamper, a spherical core head and a small-size diameter-reducing sizing ring belt. The spherical core-head composite mould pipe drawing device is characterized in that the composite mould is fixed on the drawing machine seat, one end of a drive head of the pulling seamless steel pipe passes through an inner hole of the composite mould, is clamped by the drawing clamper on the drawing machine and is also inserted into the small-size diameter-reducing sizing ring belt part of the inner hole of the composite mould through the spherical core head, the pulling seamless steel pipe moves forwards under the drawing action of the drawing machine and carries out diameter reduction and wall reduction under the cooperation of the inner hole of the composite mould and the spherical core head in the moving forward process.
Description
Affiliated technical field
The utility model relates to a kind of spherical core print compound die pipe drawing device, belongs to metal rolled technical field.
Background technology
Seamless steel tube production cold-drawn device adopts cylindrical core print single mode tube drawing mostly at present; The defective of this pipe drawing device is that draw power is bigger; Pass deformation is less, and cylindrical core print 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; Energy resource consumption is big, and production cost is high.
Summary of the invention
In order to solve the above-mentioned drawback of traditional cylindrical core print single mode pipe drawing device, the utility model provides a kind of spherical core print compound die pipe drawing device, adopts this device tube drawing that draw power is reduced, and pass deformation increases, and production efficiency improves.
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 the small size tube reducing sizing endless belt position that penetrates spherical 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 spherical core print.
The beneficial effect of the utility model is: adopt spherical core print compound die tube drawing to become the tube drawing of the tube drawing of two passages of original cylindrical core print single mode into a passage of present spherical core print compound die; Shortened the production cycle; Practiced thrift the energy; Improved production efficiency, and the more cylindrical core print of draw power reduces.

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 spherical 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 spherical core print 6.The concrete structure of compound die 3 is: the large scale tube reducing sizing endless belt 8 and small size tube reducing sizing endless belt 9 that design and produce two groups of descending arrangements of diameter dimension at the axis direction of compound die 3 endoporus side by side; 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 spherical core print 6 is: be made up of core bar 7 and spherical 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; Spherical core print 6 is spherical in shape, and its diameter is confirmed by the diameter of finished product seamless steel pipe.
Claims (1)
