Abstract

The invention relates to a process head of a cold-drawing steel tube. The process head comprises an integrated dolly clamping part (1) and a connecting part (2); wherein the maximum radial dimension of the clamping part (1) is less than or equal to the radial dimension of the connecting part (2); and the maximum radial dimension of the connecting part (2) is less than or equal to the external diameter of the steel tube blank. In service, the end terminal of the connecting part (2) is welded at one end of the steel tube blank; the cold-drawing dolly of the drawbench clamps the clamping part (1)of the process head of the cold-drawing steel tube in order to perform the cold-drawing of the steel tube; and after the steel tube cold-drawing process is finished, cut off the process head of the cold-drawing steel tube, which is reusable. The process head has the advantages of greatly increasing the work efficiency, reducing the labor intensity, saving a great deal of steel tube, and greatly increasing the rate of finished product and the economic benefit of enterprise.

Description

The technique head of cold drawing steel tube

Technical field

The present invention relates to a kind of technique head of cold drawing steel tube.

Background technology

In the production of drawn tube in order to make the nib that can be passed the drawbench drawing die by the steel pipe pipe of draw, generally all need carry out " tup " operation, need to be about to the certain-length of the steel pipe pipe of cold-drawn processing to adopt mechanical means with flat, the toe of its hammer, the steel pipe head that " hammer " crossed can extend through the nib of the drawing die of cold group of machine, clamp and carry out draw by the cold-drawn dolly, make the steel pipe of drawing forming meet needed caliber and wall thickness.But with this " tup " mode, metal loss is big, the labour intensity height.Particularly during the bigbore steel pipe of draw, spillage of material is bigger; When draw stainless steel tube or other coloured noble metal, the economic loss that spillage of material causes is more obvious.

Summary of the invention

The technical problem to be solved in the present invention is: solve in the existing drawn tube production and adopt " tup " operation, the technical problem that spillage of material is big, the utility model provides a kind of technique head of cold drawing steel tube, it is welded on steel pipe pipe end, and cooling pulls out and carries out the steel pipe draw after dolly clamps, after steel pipe drawing is shaped, the technique head of cold drawing steel tube is reusable, reduce spillage of material, reduced the production cost of drawn tube, improved economic benefit.。

The technical solution adopted for the present invention to solve the technical problems is: a kind of technique head of cold drawing steel tube, retained part and coupling part with integrative-structure, the radial dimension of retained part is smaller or equal to the radial dimension of coupling part, the coupling part radially full-size smaller or equal to steel pipe pipe external diameter.During use, the coupling part is terminal to be welded to connect with steel pipe pipe one end, and the cold-drawn dolly of drawbench is clamped the retained part of the technique head of cold drawing steel tube, carry out the steel pipe draw, after steel pipe drawing is shaped, the technique head of cold drawing steel tube is cut off, the technique head of this cold drawing steel tube is reusable

Be the retained part of the technique head that makes the clamping cold drawing steel tube that the cold-drawn dolly can be convenient and reliable, avoid the nib of technique head damage drawbench drawing die simultaneously, described retained part is shaped as cubic cylindricality, coupling part.For circular cone or cylindrical tube, improved tensile strength, between retained part and the coupling part transition portion is arranged, transition portion is a cone, transition portion and retained part and coupling part be rounding off respectively.

Coupling part and the welding of steel pipe pipe for the technique head that makes things convenient for cold drawing steel tube have groove on the tube wall of described coupling part vertically, described groove circumference uniform distribution, and quantity is more than two.

Described retained part, coupling part and transition portion are the integrative-structure that monoblock cast forms.Adopt forging type to make the technique head of cold drawing steel tube, cost of manufacture is low, can adopt the waste material in the steel pipe's production to cast, and the technique head of the cold drawing steel tube after the repeated use for several times also can melt down the technique head that is used to cast new cold drawing steel tube.

The invention has the beneficial effects as follows that the technique head of this cold drawing steel tube is not only easy to use, can improve work efficiency, reduce labour intensity and cost, and can save a large amount of stainless steel tubes, improve product lumber recovery and economic benefit.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present invention.

The specific embodiment

As Fig. 1, Fig. 2 and most preferred embodiment of the present utility model shown in Figure 3, the technique head of cold drawing steel tube, retained part 1, transition portion 3 and coupling part 2 with integrative-structure of monoblock cast one-tenth, retained part 1 is shaped as cubic cylindricality, transition portion 3 is a cone, coupling part 2 is a tapered tube shape, and transition portion 3 is arranged between retained part 1 and the coupling part 2, retained part 1 and transition portion 3, transition portion 3 and coupling part 2 difference rounding ofves.The radially full-size of retained part 1 equals transition portion 3 small end external diameters, transition portion 3 big end external diameters equal the small end external diameter of coupling part 2, coupling part 2 big end external diameters equal steel pipe pipe external diameter, offer five cone tanks 4 of circumference uniform distribution on 2 tube walls of coupling part vertically.

During use, the big end of the coupling part 2 of the technique head of cold drawing steel tube steel pipe pipe one end with the drawing of wanting is welded to connect, the cold-drawn dolly of drawbench is clamped the retained part 1 of the technique head of cold drawing steel tube, carry out the steel pipe draw, after steel pipe drawing is shaped, the technique head of cold drawing steel tube is cut off, and the cold-drawing technology head under the cutting is reusable, certainly, when using for the second time, the pipe external diameter still will adapt with the big end external diameter in coupling part, that is to say to be used for drawing pipe external diameter than the little steel pipe of pipe external diameter last time, use certain number of times after, because wearing and tearing, the cold-drawing technology head can not use, can melt down casting again, makes material obtain recycling.Adopt the technique head of this cold drawing steel tube to carry out the cold-drawn processing of stainless steel tube, not only improved work efficiency, reduced labour intensity, and saved a large amount of steel pipes, improved the lumber recovery and the economic benefit of enterprises of product greatly.
