Description
Technical field
The utility model is related to steel wire manufacture field, especially a kind of rectangular mould structure.
Background technology
In recent years, the marine petroleum development technology of China is developed rapidly, and offshore oil pipeline requirement is greatly increased.
Flexible duct is due to that can bear larger deformation, therefore, more have the advantage promoted the use of than traditional steel pipe.It is soft
Property pipe be to be manufactured using the composite of multilayer, mainly by the thermoplastic polymer material of guarantee liquid-tight, and spiral shell
Revolve the rectangular wire composition of the guarantee tubing intensity of structure winding.
This flexible pipe is higher to the surface quality requirements of reelable rectangular wire, it is desirable to which its surface must not have longitudinal direction to draw
Hinder the defects such as cut, burr and raw edges.Current rectangular wire is generally drawn using single pass stent hubbing, rolling and roller die
The production of the methods such as method is pulled out, the surface for the rectangular wire that rolling and roller die drawing method are produced easily is scratched, dimensional tolerance variations
Greatly, dimensional accuracy and surface quality can not meet the flexible pipe quality requirement higher to rectangular wire size and surface, so that
The quality of flexible pipe is set also to be affected.Single pass fix the rectangular wire produced of modulus method have surface smoothness it is good,
The advantages of dimensional tolerance is small, poker is good, but be due to single pass production, its low production efficiency, the production cycle is long.
Therefore some manufacturers are improved for its technology, and rectangular wire, but mesh are made by the way of continuous drawing
It is preceding still without a kind of mould suitable for rectangular wire drawing.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art to be applied to continuous drawing work there is provided one kind
Skill, surface smoothness is good, a kind of rectangular mould structure of high yield rate.
The utility model is adopted the technical scheme that：
A kind of rectangular mould structure, including a mould, the mould outer rim are used to be fixedly mounted with die sleeve, it is characterised in that：
The die inside makes inlet region and outlet area respectively along its axial direction both side ends, by the inlet region between outlet area
The workspace and sizing area being connected sequentially are formed with, the section inner edge of the workspace and sizing area along mould radial direction is square
Shape, is progressively reduced, institute by workspace with end to the sizing area of inlet region homonymy with the rectangular dimension of the end of outlet area homonymy
The inner dimensions that end inner dimensions of the inlet region on the outside of mould are more than workspace and the end of inlet region homonymy are stated, this goes out
The end inner dimensions that mouth region is located on the outside of mould are more than the inner dimensions of sizing area and the end of outlet area homonymy.
Moreover, end to the end with workspace homonymy that the interior cause of the inlet region is located on the outside of mould is formed with surface
Smooth curved surface, the size of the inlet region inner edge progressively reduces.
Moreover, the relative inwall in the outlet area inner edge every two, the relative inwall in the outlet area inner edge every two, prolong along it
It is 55 ° to 65 ° to stretch the angular range that direction formed.
Moreover, described two groups of relative inwalls in workspace are along respective bearing of trend, the angle model of the working cone angle formed
Enclose for 16 ° to 24 °.
Moreover, the sizing area is fillet with the end inner edge corner of outlet area homonymy, the radius of corner scope is 1 millimeter
To 3.5 millimeters.
Advantage of the present utility model and good effect are：
In the utility model, inlet region is used for steel wire and feeds and lubricate, and workspace is by its length and working cone angle to steel
Silk plastic deformation, sizing area obtains being adapted to the steel wire of size finish by its inside dimension, and outlet area is used to distribute drawing steel
The deformation heat of silk；Make curved surface and be easy to lubricant to enter workspace in inlet region inner edge, it is ensured that it is not abraded by the edge of nib；Go out
Mouth region opposite sides end face institute shape is angled 60 °, it is ensured that the opening of outlet area, distributes the deformation heat of drawn steel wire, protection
Sizing area will not burst apart, and when shutting down, wire rod is abraded because of reversing；By suitable working cone angle cause upper pressure and
The minimum of making a concerted effort of frictional force；Make fillet in sizing area end inner edge, it is ensured that steel wire is deformed in mould and can filled, it is to avoid excessively squeeze
Wound.
