Abstract

The utility model relates to a circular tubular product lead alloy hot extrusion die, include from preceding after to the last mould and the lower mould that set up of stack in proper order the feeding terminal surface of last mould is followed circumference and is evenly set up the reposition of redundant personnel bridge, arranges the branch discharge orifice between the reposition of redundant personnel bridge, and the ejection of compact terminal surface of going up the mould sets up the mold core, the ejection of compact terminal surface of reposition of redundant personnel bridge sinks to forming to sink the bridge. The feed end of lower mould sinks to forming the seam room, and seam room bottom sets up nib and export, and the mold core and the nib cooperation of going up the mould form the fashioned die cavity of circular tubular product. The entrance point and the exit end edge of nib set up nib entry R angle and nib export R angle respectively. The utility model discloses can the circular tubular product of high -efficient production lead alloy, heavy bridge design through last mould goes out the charge level has effectively increased the seam degree of depth, has increased seam pressure for the density of lead alloy increases. And controlled the tool that causes because of the not firm face of seam inflation well or flatten after the circular tubular product lead alloy welding seam department phenomenon that easily ftractures.

Description

Circular pipe metal hot-extrusion mold
Technical field
The utility model relates to a kind of metal hot-extrusion mold, especially a kind of circular pipe metal hot-extrusion mold, belongs to commercial lead alloy material technical field of mold.
Background technology
Because metal has, density is large, fusing point is low, the corrosion-resistant and protection features such as radiological performance is good, and other metals cannot substitute.In large-scale power, particularly in recent years apply circular pipe lead alloy material more.
But in circular pipe lead alloy material, there is following defect in the metal circular pipe (as shown in Figure 1) produced by hot extrusion.One: rough surface, tissue looseness, affects outward appearance and mechanical strength.This just makes the circular pipe metal produced by hot extrusion can not reach its instructions for use.Its two: commissure is easy to crack, during use through mechanical swelling or flatten after circular pipe metal commissure easy to crack.This just makes the circular pipe metal produced by hot extrusion can not reach its instructions for use.Want it to produce qualified product by hot extrusion and only try every possible means from the design aspect of mould more.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of circular pipe metal hot-extrusion mold, can High-efficient Production circular pipe.
According to the technical scheme that the utility model provides, described circular pipe metal hot-extrusion mold, comprises the upper die and lower die superposing setting from A-P successively; It is characterized in that: circumferentially evenly arrange shunting bridge at the charging end face of described patrix, arrange tap hole between shunting bridge, the discharging end face of patrix arranges core rod; The discharging end face of described shunting bridge sinks to being formed heavy bridge.
Further, sink to forming bonding container at the feed end of described counterdie, nib and outlet are set bottom bonding container, the die cavity that the core rod of patrix and nib coordinate formation circular pipe shaping.
Further, the entrance point of described nib and port of export edge arrange approach R angle and orifice exit R angle respectively.
Further, entrance choked flow angle is provided with joint, described approach R angle.
Further, described upper die and lower die are by screw and pin close-fitting.
Further, described shunting bridge is four, and tap hole is four.
Circular pipe metal hot-extrusion mold described in the utility model, energy High-efficient Production metal circular pipe, is gone out the heavy bridge design of charge level, effectively increases the seam degree of depth, add seam pressure, the density of metal is increased by patrix.Then approach designs a R angle, and design an entrance choked flow angle with joint, R angle, work band exit design one exports R angle.Control well because of seam loosely the tool that causes of face expand or circular pipe metal commissure phenomenon easy to crack after flattening.Also very ideally solve rough surface, tissue looseness, affect the situation of outward appearance and mechanical strength.

Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Fig. 2 ~ Fig. 9: as described in circular pipe metal hot-extrusion mold comprise patrix 1, counterdie 2, shunting bridge 3, tap hole 4, core rod 5, heavy bridge 6, bonding container 7, nib 8, outlet 9, approach R angle 10, orifice exit R angle 11, entrance choked flow angle 12 etc.
As shown in Figure 2 and Figure 3, the utility model comprises the patrix 1 and the counterdie 2 that superpose setting from A-P successively, and patrix 1 and counterdie 2 are by two screws and two pin close-fittings.
As shown in Fig. 4, Fig. 5, Fig. 6, circumferentially evenly arrange four shunting bridges 3 at the charging end face of described patrix 1, arrange four tap holes 4 between shunting bridge 3, the discharging end face of patrix 1 arranges core rod 5; The discharging end face of described shunting bridge 3 sinks to being formed heavy bridge 6, can effectively deepen seam space, increase seam pressure.
As shown in Fig. 7, Fig. 8, Fig. 9, sink to forming bonding container 7, arrange nib 8 and outlet 9 bottom bonding container 7 at the feed end of described counterdie 2, the core rod 5 of patrix 1 and nib 8 cooperation form the shaping die cavity of circular pipe; The entrance point of described nib 8 and port of export edge arrange approach R angle 10 and angle 10, orifice exit R angle 11, approach R respectively can allow metal can flow into nib 8 very smoothly, prevents because nib 8 is rough that lead alloy surface that is that cause is coarse; Be provided with entrance choked flow angle 12 with joint, described approach R angle 10, play choked flow, guide effect, allow metal density increase, seam is tightr, and work strip is flow through more glossily in surface.Orifice exit R angle 11 can allow the metal flowing through work strip not rough because exporting, and causes to glue to hinder lead alloy surface.
The utility model is in extrusion process, metal is after shunting bridge 3 is shunted, through bonding container 7, in bonding container 7, seam becomes one metal again, because patrix 1 discharging end face have employed the design of heavy bridge 6, effectively increase the seam degree of depth, add seam pressure, the density of metal is increased.Then when metal flows into nib, due to its entry design one R angle, allow the inflow nib that metal can be very smooth, prevent the lead alloy surface caused because nib is rough coarse.Design an entrance choked flow angle with joint, R angle, it plays choked flow, guide effect, allows metal, and density increases, and seam is tightr, and work strip is flow through more glossily in surface.Exporting R angle at work band exit design one after combustion, making the metal that flows through work strip not rough because exporting, what cause stickyly hinders the existing picture of lead alloy surface.Control the expansion because seam loosely causes or the circular pipe metal commissure phenomenon easy to crack after flattening well.Also very ideally solve rough surface, tissue looseness, affect the situation of outward appearance and mechanical strength.
