Abstract
The utility model relates to a push-pull-type seamless tapered pipe, which is manufactured in the way that a standard seamless pipe is pressed into a tapered die with a pressing machine. The thickness of the shell of the seamless steel pipe ranges from 1 to 20 mm; the tapered pipe is 0.5 to 3 meters long; the caliber of the tapered pipe is 159 to 630 mm. The utility model has the advantages of standard conicity, simplicity to be pushed and pulled, is operated safely; the density of the tapered pipe is increased; the cost is low; the conicity is large; the production efficiency is high; the cost is reduced by 5 times by comparing the utility model with the mechanical processing method.
Description
Technical field
The utility model relates to the seamless conical steel pipe that a kind of smelter is used.
Background technique
Traditional taper seamless steel pipe all adopts machining process to finish, and the conical pipe of its processing is nonstandard, and operates dangerous; The expense of taking a lot of work material, cost is higher.
Summary of the invention
The purpose of this utility model provides and a kind ofly pushes away the seamless conical pipe of the formula of pulling out with what tube drawing technology was made, and its mechanical property is better than the taper seamless steel pipe that processes with mechanical process, and its cost is low, and tapering is big, the manufacturing efficiency height.
For achieving the above object, the utility model is achieved through the following technical solutions:
Push away the seamless conical pipe of the formula of pulling out, it is characterized in that: this taper seamless steel pipe is with press machine the standard weldless tube to be compressed into the cone mould to make, this seamless steel pipe wall thickness 1-20mm; Taper Pipe length 0.5-3m; Bore Φ 159-630mm.
For long tapering pipe, the described seamless conical pipe of the formula of pulling out that pushes away is to be welded together by several sections Taper Pipes to constitute.
The utility model has the advantages that the tapering standard, pushing is simple, handling safety, increases conical pipe density; Cost is low, and tapering is big, the manufacturing efficiency height; Can reduce cost 5 times than machining process.
Description of drawings
Fig. 1 is the structural representation that pushes away the seamless conical pipe of the formula of pulling out.
Embodiment
Seeing Fig. 1, push away the seamless conical pipe of the formula of pulling out, is after coating lubriation material in the taper die 1 seamless steel pipe 2 usefulness press machinees or horizontal pushing machine to be compressed into the cone mould to the standard weldless tube earlier, makes weldless tube become the taper seamless steel pipe, this seamless steel pipe wall thickness 1-20mm; Taper Pipe length 0.5-3m; Bore Φ 159-630mm.
Surpass 1.5 meters long taper reducing seamless steel pipe for making, as make 6 meters long tapering pipe, several sections 1.5 meters long Taper Pipes are welded together.
Claims (2)
1. push away the seamless conical pipe of the formula of pulling out, it is characterized in that: this taper seamless steel pipe is with press machine the standard weldless tube to be compressed into the cone mould to make, this seamless steel pipe wall thickness 1-20mm; Taper Pipe length 0.5-3m; Bore Φ 159-630mm.
2. the seamless conical pipe of the formula of pulling out that pushes away according to claim 1 is characterized in that: this pushes away the seamless conical pipe of the formula of pulling out is to be welded together by several sections Taper Pipes to constitute.
