Abstract
The utility model relates to a low -cost high rigidity aluminium alloy extrusion tooling, its structure includes mould and lower mould, is equipped with the section bar shaping and extrudes the passageway in last mould, is equipped with section bar forming die core and distributes at the peripheral feedstock channel of section bar forming die core in the lower mould, characterized by division has a communicating annular of interior circle of extruding the passageway with the section bar shaping in the interior port department that the passageway was extruded in the section bar shaping of last mould the scarf joint has alloy steel to inlay the ring in the annular, the interior circle of ring and the interior round coplane that the passageway was extruded in the section bar shaping are inlayed to alloy steel, the ring was inlayed to alloy steel outer terminal surface with go up the inner facial features parallel and level of mould. The utility model discloses make ordinary extrusion tooling reach alloy steel mold's hardness effect and result of use, the mould need not carry out the nitrogenize stiffened to be handled for the turnover of mould, practiced thrift mould nitrogenize cost, can improve the yield and the finish of aluminium alloy greatly in the use, improve the mould utility life -span.
Description
Technical field
This utility model relates to a kind of aluminium section bar extrusion die, specifically a kind of low cost high hardness aluminium section bar extruding mould.
Background technology
Along with quickly propelling of the large-scale capital expenditure of China and process of industrialization, aluminium section bar is as application material important in building field and mechanical industry field, yield and the consumption figure of its whole industry rapidly increase, and China also suddenly becomes aluminium section bar production base the biggest in the world and consumption market.Through the rapid growth up to last decade, China's aluminum profile industry has stepped into new developmental stage and has shown many new development trends.Along with the raising to product quality requirement of national industrial policies, industry restructuring and consumer, the present situation that aluminum processing industry is extensive, added value is low is altered in steps, cross over and increase the primary developmental stage being characterized with quantity, initially entered to improve product inherent quality, enrich product category, the new stage relying on comprehensive strength to participate in market competition.
The production of existing aluminium section bar is substantially the production and processing mode using mould extrusion, and wherein the hardness of mould is a key factor of yield rate and the surface smoothness concerning aluminium section bar, is also the key factor concerning mould service life itself.Owing to the hardness of the special steel material of China's production is the most relatively low, making aluminium section bar extrusion die with it, die hardness can not meet use requirement.And using the steel alloy of import to make aluminium section bar extrusion die, its hardness can reach HRA89, although meeting mold use requirement, but owing to the price of import steel alloy is sufficiently expensive, thus can have a strong impact on the profit margin of aluminium profile product.So, the mould mode of production of compromise is after the domestic H13# special steel of employing is fabricated to die blank at present, then carries out nitrogenizing stiffened process, to meet the hardness requirement of mould.
But, the weak point that this mould mode of production exists, is first that the manufacturing process of mould is many, and the cycle is long, affects the turnover of mould；Secondly, the hardness after H13# special steel via nitride stiffened processes technique can only achieve HRA60, and the yield rate of the aluminium section bar extruded and surface smoothness etc. are still had certain adverse effect.
Utility model content
The purpose of this utility model is just to provide a kind of low cost high hardness aluminium section bar extruding mould, and the manufacturing process multicycle length existed to solve the mould of existing nitrogen treatment affects the hardness of mould turnover and nitridation stiffened process and is still difficult to meet use the problem required.
This utility model is achieved in that a kind of low cost high hardness aluminium section bar extruding mould, product moulding extrusion passage it is provided with in upper mold, in lower mold, it is provided with product moulding core rod and is distributed in the feeding-passage of product moulding core rod periphery, it is characterized in that, product moulding in upper mold is extruded and is had the annular groove that the inner circle with product moulding extrusion passage communicates at the inner port of passage, in described annular groove, interlocking has steel alloy to inlay ring, the inner circle of described steel alloy edge ring is coplanar with the inner circle of product moulding extrusion passage, the outer face of described steel alloy edge ring and the inner face flush of described upper mold.
Utility model is provided with steel alloy male in the front end of the product moulding core rod of lower mold, and the front end of described steel alloy male is stretched in the front port of described product moulding extrusion passage of upper mold.
This utility model arranges steel alloy edge ring and steel alloy male by the key position in mould molding extrusion channel, the extruded place on mould is made to be the alloy steel material of high rigidity, common extrusion die thus can be made to have reached stiffening effect and the using effect of Alloy-steel mold, the hardness at its extruded place is up to HRA89, therefore, this mould is not required to carry out nitrogenizing stiffened and processes, Step for Die & Mold Nitridation can be saved and process technique, accelerate the turnover of mould, save Step for Die & Mold Nitridation cost, and in use it is greatly improved yield rate and the surface smoothness of aluminium section bar, improve the mold use life-span.
This utility model structure arranges rationally, charging smoothness, and the Surface of profile of extrusion is smooth, and work efficiency is high, and mould volume is little, convenient for installation and maintenance.

Detailed description of the invention
As it is shown in figure 1, this utility model includes the upper mold 3 of cylinder and cylindrical 4 two ingredients of lower mold, upper die and lower die all use H13# special steel to make molding.
The product moulding extrusion passage 7 that axial circular is poroid is had in the center of upper mold 3, the annular groove that the inner circle with product moulding extrusion passage communicates is had at the inner port of product moulding extrusion passage 7, in annular groove, interlocking has steel alloy to inlay ring 1, the inner circle of described steel alloy edge ring 1 is coplanar with the inner circle of product moulding extrusion passage 7, the outer face of steel alloy edge ring 1 and the inner face flush of upper mold 3.
As shown in Figure 1 and Figure 2, being connected by three cross structures being uniformly distributed along the circumference and have product moulding core rod 5 in lower mold 4, the neutral between three cross structures constitutes the feeding-passage 6 around section bar formation die core.Be provided with steel alloy male 2 in the front end of product moulding core rod 5, steel alloy male 2 is fixed by screws in the front end of product moulding core rod 5.The front end of steel alloy male 5 is stretched in the front port of product moulding extrusion passage 7 of upper mold 3, and coordinates with the steel alloy edge ring 1 in upper mold 3, the crucial force part of the extrusion molding in composition mould molding extrusion channel.Owing to the hardness of steel alloy male 2 with steel alloy edge ring 1 can reach HRA89, thus, mould entirety is not required to carry out nitrogenizing stiffened and processes, and has saved Step for Die & Mold Nitridation cost, and in use it is remarkably improved yield rate and the surface smoothness of aluminium section bar, improves the mold use life-span.
