Abstract
The utility model discloses a long core rod steel pipe drawing device which mainly comprises a cylindrical long core rod, a seamless steel pipe to be drawn, a drawing machine and a drawing die and is characterized in that the cylindrical long core rod with a cone angle at an end is processed and manufactured according to the material quality and size required by the drawing technology, and the end with the cone angle of the cylindrical long core rod is penetrated into the inner wall of the seamless steel pipe to be drawn with a flattened end and moves forward to the flattened end. The process of the drawing work is that the seamless steel pipe to be drawn and the cylindrical long core rod penetrated into the inner wall of the seamless steel pipe to be drawn move forward synchronously under the drawing effect of the drawing machine, and diameter reduction and wall reduction are carried out under the combined effect of the drawing die and the cylindrical long core rod in the moving forward process of the seamless steel pipe to be drawn.
Description
Affiliated technical field
The utility model relates to a kind of long plug pipe drawing device, belongs 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 utility model 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 utility model solves the technical scheme that its technical problem adopted: 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 beneficial effect of the utility model is: adopt long plug tube drawing draw power to reduce, adapt to the draw of wall tube material as thin as a wafer.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the front view of the utility model.
Fig. 2 is the front view of the utility model withdrawing pattern.
Fig. 3 is the left view of the utility model withdrawing pattern.
Fig. 4 is the A-A profile of the utility model withdrawing pattern.
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.
