Abstract
The invention relates to a floating core rod pipe-drawing device, which mainly consists of a floating core rod ejector pin, a seamless steel pipe to be drawn, a floating core rod, a drawing die, a diameter-reducing area and a diameter-sizing area, and is characterized in that: the floating core rod is arranged in an inner hole of the seamless steel pipe to be drawn; the floating core rod is conveyed to a diameter-reducing area part and a diameter-sizing area part of an inner hole of the drawing die through the floating core rod ejector pin; and then, the floating core rod ejector pin withdraws to reset, and the floating core rod can always be kept at the diameter-reducing area part and the diameter-sizing area part of the inner hole of the drawing die in a drawing process through the friction generated by the contacting between the outside surface of the floating core rod and the inside surface of the seamless steel pipe to be drawn in the drawing process.
Description
Affiliated technical field
The present invention relates to a kind of floating core rod pipe drawing device, belong to metal rolled technical field.
Background technology
Seamless steel tube production cold-drawn device adopts the plug pipe drawing device of band pull bar mostly at present, and the defective of this pipe drawing device is in process of tube plug drawing mill, to shake at steel pipe internal-surface generation jutter because of pull bar, influences steel tube surface quality.
Summary of the invention
In order to solve the above-mentioned drawback of traditional pull bar plug pipe drawing device, the present invention provides a kind of floating core rod pipe drawing device, adopts this device to reduce than its draw power of pull bar plug tube drawing, and deflection increases, and production efficiency improves.
The technical solution adopted for the present invention to solve the technical problems is: make the pull bar plug pipe drawing device in traditional seamless steel tube production process into push rod floating core rod pipe drawing device; This pipe drawing device adopts the floating core rod that does not have pull bar; Floating core rod is placed in the seamless steel pipe inner bore of treating drawing; The seamless steel pipe of treating drawing is placed in the endoporus of withdrawing pattern; The operating position of floating core rod is at the diameter reducing area and the sizing area position of withdrawing pattern endoporus; The course of work is: through the floating core rod push rod floating core rod is delivered to the diameter reducing area and the sizing area position of withdrawing pattern endoporus, then the floating core rod push rod is return and is resetted, and contacts between the outer surface that in process of tube plug drawing mill, leans on floating core rod and the seamless steel pipe inner surface of treating drawing and the frictional force that produces remains at floating core rod to pull out the film endoporus in process of tube plug drawing mill diameter reducing area and sizing area position.
The invention has the beneficial effects as follows: adopt the floating core rod tube drawing to eliminate the jutter that traditional pull bar plug tube drawing produces at steel pipe internal-surface because of the pull bar shake, this device reduces than its draw power of pull bar plug tube drawing, and deflection increases, and production efficiency improves.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a front view of the present invention.
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.
1. floating core rod push rods among the figure are 2. treated the seamless steel pipe of drawing, 3. floating core rod, 4. support, 5. withdrawing pattern, 6. puller gripper, 7. diameter reducing area, 8 sizing areas.
The specific embodiment
In Fig. 1, Fig. 2, Fig. 3; Withdrawing pattern 5 is inlayed and is fixed on the support 4; Seamless steel pipe 2 its ends of taking the lead of treating drawing pass the diameter reducing area 7 of withdrawing pattern 5 endoporus and are clamped by the puller gripper on the drawbench 6 with sizing area 8 backs; Then floating core rod 3 gets into the diameter reducing area 7 and sizing area 8 positions of withdrawing pattern 5 endoporus under the thrust of floating core rod push rod 1, treats that then the seamless steel pipe 2 of drawing moves ahead under the action of traction of drawbench through puller gripper 6, under the diameter reducing area 7 and the sizing area 8 of withdrawing pattern 5 endoporus act on; Treat that the seamless steel pipe 2 of drawing at first passes through diameter reducing area 7 tube reducings of withdrawing pattern 5 endoporus; Then through sizing area 8 sizings, in the process of tube reducing and sizing, the inwall of treating the seamless steel pipe 2 of drawing contacts generation frictional force remains at floating core rod 3 to pull out film 5 in process of tube plug drawing mill diameter reducing area 7 and sizing area 8 positions with the outer wall of floating core rod 3; Then floating core rod push rod 1 is return and is resetted, and treats that the seamless steel pipe 2 of drawing is realized tube reducing and sizing under the acting in conjunction of withdrawing pattern 5 and floating core rod 3.
