Abstract
A novel floating mandrel mainly comprises a novel floating mandrel body, a seamless steel tube to be drawn, a cylinder, a novel floating mandrel sizing area, a top end chamfering area and a concave-surface belt. The novel floating mandrel is characterized in that a cylindrical portion, which closely contacts with the inner wall of the seamless steel tube to be drawn, of the front end of the novel floating mandrel body, namely a portion between the novel floating mandrel sizing area and the top end chamfering area forms the concave-surface belt by means of processing and removing partial materials on the outer surface of the cylinder, and the concave-surface belt does not contact with the inner wall of the seamless steel tube to be drawn. Due to the structure, friction area produced when the outer surface of the cylinder of the novel floating mandrel contacts with the inner surface of the seamless steel tube to be drawn is reduced, and a wall thinning sizing function of the novel floating mandrel is unaffected.
Description
Affiliated technical field
The utility model relates to a kind of novel floating core rod, belongs to metal rolled technical field.
Background technology
At present its periphery of floating core rod of adopting of seamless steel tube production cold-drawn device float plug tube drawing be the smooth face of cylinder mostly, and the frictional force that produces during the drawing operation between the smooth face of cylinder of this integral body and steel pipe inwall is big, and consumption of power is big, the production cost height.
Summary of the invention
In order to solve the above-mentioned drawback of smooth face of cylinder floating core rod, the utility model provides a kind of novel floating core rod of the non-smooth face of cylinder.
The utility model solves the technical scheme that its technical problem adopted: at the leading section and the cylinder position of treating that the drawing seamless steel tubes inwall closely contacts of novel floating core rod; Be the position between novel floating core rod sizing area and the break corner district, cylindrical outer surface processing removing part material form one section not with the concave surface endless belt of treating that the drawing seamless steel tubes inwall contacts.Adopt this structure both to reduce the cylindrical outer surface of novel floating core rod and contact the rubbing surface that produces with treating the drawing seamless steel tubes inner surface, what do not influence novel floating core rod again subtracts wall sizing function,
The beneficial effect of the utility model is: adopt this novel floating core rod tube drawing with concave surface endless belt, draw power reduces, and energy resource consumption reduces, and production efficiency improves.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

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.
Fig. 5 is the front view of the novel floating core rod of the utility model.
1. novel floating core rod push rods are 2. treated drawing seamless steel tubes among the figure, 3. novel floating core rod, 4. support, 5. withdrawing pattern; 6. puller gripper, 7. drawbench, 8. diameter reducing area, 9. sizing area; 10. novel floating core rod sizing area, 11. concave surface endless belt, 12. break corner districts, 13. cylinders.
The specific embodiment
In Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5; Withdrawing pattern 5 is inlayed and is fixed on the support 4; Treat that the diameter reducing area 8 that drawing seamless steel tubes 2 its ends of taking the lead pass withdrawing pattern 5 endoporus clamped by the puller gripper on the drawbench 76 with sizing area 9 backs, then novel floating core rod 3 gets into the diameter reducing area 8 and sizing area 9 positions of withdrawing pattern 5 endoporus under the thrust of novel floating core rod push rod 1; The structure of novel floating core rod 3 is: at the leading section and cylinder 13 positions of treating that drawing seamless steel tubes 2 inwalls closely contact of novel floating core rod 3; It is the position between novel floating core rod sizing area 10 and the break corner district 12; The outer surface of cylinder 13 processing removing part material form one section not with the concave surface endless belt 11 of treating that drawing seamless steel tubes 2 inwalls contact; The outer surface that adopts this structure both to reduce the leading section cylinder 13 of novel floating core rod 3 contacts the rubbing surface that produces with treating drawing seamless steel tubes 2 inner surfaces, and what do not influence novel floating core rod 3 again subtracts wall sizing function.
