Abstract
The invention discloses a double-pore stainless steel composite pipe cold-drawing mold core which is characterized in that the traditional central single pore concept is changed, a conventional mold core is uniformly and symmetrically designed to be provided with double mold holes along the diameter direction, the mold core with the double mold holes is arranged in a mold sleeve, the mold sleeve is arranged on a cold-drawing machine template, and during installation, a central line of the double mold holes of the mold core is perpendicular to the ground. Only the width of a clamp in a conventional cold drawing machine needs to be slightly increased, other equipment and facilities do not need to be additionally arranged, the operation is simple, the machining is convenient, increase of the cost is avoided, and the production efficiency is doubled.
Description
Technical field
The present invention relates to stainless steel composite pipe cold-drawn technical field, be specifically related to a kind of diplopore stainless steel composite pipe cold-drawn core rod.
Background technology
As one of bimetal compound pipeline of up-to-date development, stainless steel composite pipe production major part all adopts cold-drawn machine-shaping at present.Cold-drawn not only makes stainless steel and two kinds of pipelines of carbon steel very closely be combined into and be integrated, and appearance and size precision, and tolerance is little, can also improve compound rear mechanics of piping performance simultaneously.
But cold-drawing technology has a critical defect, be exactly that production efficiency is low, 6 meters of long pipelines of every production, light drawing process just needs two minutes.The large size pipeline every workday generally can be produced 10 tons of left and right, small dimension pipeline is such as ￠ 15.8～￠ 25.4 series, every workday generally can only be produced 1～1.5 ton, production efficiency low, strengthen undoubtedly stainless steel composite pipe production cost, also seriously restricted the sound development of stainless steel composite pipe cold-drawing technology.
Summary of the invention
The present invention is directed to the problems referred to above, invent a kind of diplopore stainless steel composite pipe cold-drawn core rod, be exclusively used in 5 specification stainless steel composite pipe cold-drawn processing of ￠ 15.8～￠ 25.4 series, compare original single hole cold-drawn core rod, efficiency just in time can double.
The technical solution adopted in the present invention is as follows:
A kind of diplopore stainless steel composite pipe cold-drawn core rod, it is characterized in that changing traditional center single hole concept, existing core rod is designed symmetrically and is processed into bimodulus hole along diametric(al), core rod is placed in die sleeve, die sleeve is arranged in drawbench template, when installation, keep core rod bimodulus centerline hole vertical with ground.
Lengthen existing drawbench clamp width, make it to be slightly larger than bimodulus hole width.Two stainless steel composite pipes to be processed are worn as bimodulus hole at every turn, started drawbench, drawbench clamp is clamped two stainless steel composite pipes and from nib, is passed simultaneously, completes cold-drawn production process.
The invention has the beneficial effects as follows:
The present invention designs symmetrically and is processed into bimodulus hole along diametric(al) by repacking existing single hole core rod design into core rod, only need to extend a little existing drawbench clamp width, do not need to increase other any installations and facilities, simple to operate, easy to process, without increasing cost, production efficiency but doubles.
Accompanying drawing explanation
Accompanying drawing 1 is existing stainless steel composite pipe single hole cold-drawn mold insert structure schematic diagram.
In accompanying drawing 1,1 is cold-drawn core rod die body, and 2 is single mode hole, cold-drawn core rod center.
Accompanying drawing 2 is stainless steel composite pipe diplopore cold-drawn mold insert structure schematic diagram of the present invention.
In accompanying drawing 2,1 is diplopore cold-drawn core rod die body, and 2,3 is cold-drawn core rod bimodulus hole.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
The existing single hole cold-drawn of accompanying drawing 1 core rod, is just processing single through hole along core rod center line, can only pass a stainless steel composite pipe to be processed at every turn.Accompanying drawing 2 diplopore cold-drawn core rods of the present invention, it is characterized in that changing traditional center single hole concept, core rod is designed symmetrically and is processed into bimodulus hole along diametric(al), be placed in die sleeve with the core rod in bimodulus hole, die sleeve is arranged in drawbench template, when installation, keep core rod bimodulus centerline hole vertical with ground.
Lengthen existing drawbench clamp width, make it to be slightly larger than bimodulus hole width.Two stainless steel composite pipes to be processed are worn as bimodulus hole at every turn, started drawbench, drawbench clamp is clamped two stainless steel composite pipes and from nib, is passed simultaneously, completes cold-drawn production process.
The present invention designs symmetrically and is processed into bimodulus hole along diametric(al) by repacking existing single hole core rod design into core rod, only need to extend a little existing drawbench clamp width, do not need to increase other any installations and facilities, simple to operate, easy to process, without increasing cost, production efficiency but doubles, and has good economic benefit.
More than describing is explanation of the invention, is not limitation of the invention, and limited range of the present invention is referring to claim, and without prejudice to basic structure of the present invention in the situation that, the present invention can do any type of modification.
Claims (2)
1. stainless steel composite pipe cold-drawn diplopore core rod, is characterized in that changing traditional center single hole concept, and existing core rod is designed symmetrically and is processed into bimodulus hole along diametric(al).
2. according to claim 1, described stainless steel composite pipe cold-drawn diplopore core rod, is characterized in that described diplopore core rod is placed in die sleeve, and die sleeve is arranged in drawbench template, when installation, keeps core rod bimodulus centerline hole vertical with ground.
