Abstract
The invention provides a long-core-rod drawing device. The device mainly consists of a cylindrical long core rod, a seamless steel tube to be drawn, a drawing machine and a drawing die, and is characterized in that the cylindrical long core rod with one taper-angle end is processed and manufactured according to the material and size required for a drawing process, and the taper-angle end of the cylindrical long core rod is inserted into the inner wall of the seamless steel tube to be drawn with a driven head end and moves ahead to the driven head end. The drawing process is as follows: the seamless steel tube to be drawn and the cylindrical long core rod which is inserted into the inner wall of the seamless steel tube synchronously move ahead under the drawing action of the drawing machine; and during the advancing process of the seamless steel tube to be drawn, the diameter of the seamless steel tube is reduced and the wall of the tube is thinned under the combined action of the drawing die and the cylindrical long core rod.
Description
Affiliated technical field
The present invention relates to a kind of long plug pipe drawing device, belong to metal rolled technical field.
Background technology
Seamless steel tube production cold-drawn device its plug when carrying out the cold-drawn operation is motionless through diameter reducing area and sizing area position that core bar is positioned at withdrawing pattern at present, and the defective of this device is: the frictional force between pipe and plug is big, the draw of incompatibility light-wall pipe.
Summary of the invention
In order to solve the defective of said fixing plug pipe drawing device, the present invention provides the long plug pipe drawing device of a kind of plug and tube drawing synchronous operation, adopts this device to reduce 80% than its draw power of stationary core rod tube drawing, adapts to the draw of wall tube material as thin as a wafer.
The technical solution adopted for the present invention to solve the technical problems is: the cylindrical long plug that material that requires according to drawing process and dimensioned are made an end band cone angle penetrates an end takes the lead treat the drawing seamless steel tubes inwall and proceed to the end of taking the lead with an end of cylindrical long plug band cone angle.Operation principle and process are: treat that its end of taking the lead of drawing seamless steel tubes at first passes the withdrawing pattern 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 withdrawing pattern and cylindrical long plug.
The invention has the beneficial effects as follows: adopt long plug tube drawing draw power to reduce, adapt to the draw of wall tube material as thin as a wafer.

Fig. 2 is the front view of withdrawing pattern of the present invention.
Fig. 3 is the left view of withdrawing pattern of the present invention.
Fig. 4 is the A-A profile of withdrawing pattern of the present invention.
1. cylindrical long plugs are 2. treated drawing seamless steel tubes among the figure, 3. support, 4. withdrawing pattern, 5. puller gripper, 6. drawbench, 7. diameter reducing area, 8. sizing area.
The specific embodiment
In Fig. 1, Fig. 2, Fig. 3, Fig. 4; The cylindrical long plug 1 that material that requires according to drawing process and dimensioned are made an end band cone angle; Treat drawing seamless steel tubes 2 inwalls and proceed to the end of taking the lead that with what an end of cylindrical long plug 1 band cone angle penetrated that an end takes the lead withdrawing pattern 4 is inlayed and is fixed on the support 3; Operation principle and process are: treat that the diameter reducing area 7 that drawing seamless steel tubes 2 its ends of taking the lead pass withdrawing pattern 4 endoporus clamped by the puller gripper on the drawbench 65 with sizing area 8 backs; Then the end with cylindrical long plug 1 band cone angle penetrates the inwall of treating drawing seamless steel tubes 2 and proceeds to the end of taking the lead of treating drawing seamless steel tubes 2; Treat under the action of traction of drawbench 6 that then drawing seamless steel tubes 2 and the cylindrical long plug 1 that penetrates its inwall move ahead synchronously, treat that drawing seamless steel tubes 2 implements tube reducing down and subtract wall in the acting in conjunction of withdrawing pattern 4 and cylindrical long plug 1 in the process that moves ahead.
Claims (3)
1. one kind long plug pipe drawing device, mainly by cylindrical long plug, treat that drawing seamless steel tubes, drawbench, withdrawing pattern form, it is characterized in that: the cylindrical long plug that material that requires according to drawing process and dimensioned are made an end band cone angle.
2. a kind of long plug pipe drawing device according to claim 1 is characterized in that: an end of cylindrical long plug band cone angle is penetrated an end takes the lead treat the drawing seamless steel tubes inwall and proceed to the end of taking the lead.
3. a kind of long plug pipe drawing device according to claim 1; It is characterized in that: treat that under the action of traction of drawbench 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 withdrawing pattern and cylindrical long plug.
