Abstract
The invention discloses a large-caliber aluminum alloy extruded tube die which comprises ten shunting holes and a welding room, wherein the depth of the welding room is 10mm-15mm. The large-caliber aluminum alloy extruded tube die with the scheme can ensure the welding quality of aluminum alloy, and the service life of the die is prolonged.
Description
Technical field
The present invention relates to a kind of mould, relate to specifically the aluminium alloy extruded pipe mold of a kind of heavy caliber.
Background technology
When the large pipe of design, need to consider 2 points, the one, mould strength, the 2nd, welding quality.The number in shunting hole, the degree of depth of seam chamber, the empty cutter degree of depth of upper mould core, the structure of two floor seam chambers all can directly have influence on intensity and the welding quality of mould.The aluminium alloy extruded pipe mold design of traditional heavy caliber has following characteristics:
1. in order to increase the intensity of patrix, the number of shunting the hole is few, and the area of shunting the hole is large, and the shunting bridge is wide;
2. in order to guarantee the welding quality of section bar, the degree of depth of seam chamber is darker, generally is designed into 60-70mm;
3. the degree of depth of the lower empty cutter of upper mould core is the 25mm left and right, and this point is also in order to guarantee welding quality;
4. counterdie work band is all consistent, is generally 8-12mm.
There is following problem in said structure:
1. the minimizing of shunting hole number must cause that shunting bridge widens, and causes welding quality poor;
2. the seam chamber is excessively dark, the corresponding lengthening of upper mould core, and core rod intensity is low;
3. the lower empty cutter of upper mould core is excessively dark, and the core rod lifting surface area increases, and core rod intensity is low;
Therefore, welding quality often appears in the pipe that diameter surpasses 500mm in extrusion process bad, the situation that die life is low.
Summary of the invention
The purpose of this invention is to provide the aluminium alloy extruded pipe mold of a kind of heavy caliber, its life and welding quality improve.
In order to realize such scheme, technical solution of the present invention is: the aluminium alloy extruded pipe mold of a kind of heavy caliber, comprise shunting hole, seam chamber, and the number in described shunting hole is 10, the seam chamber degree of depth is 10-15mm.
The aluminium alloy extruded pipe mold of heavy caliber of the present invention, wherein, the work band of described shunting hole corresponding part is provided with and hinders the angle, and hindering the angle is 1.5 °.
The aluminium alloy extruded pipe mold of heavy caliber of the present invention wherein, also comprises two floor seam chambers.
After adopting such scheme, the aluminium alloy extruded pipe mold of heavy caliber of the present invention has guaranteed the welding quality of aluminium alloy, and extends the life-span of mould.
Description of drawings
Fig. 1 is the layout in the aluminium alloy extruded pipe mold shunting of heavy caliber of the present invention hole;
Fig. 2 is the layout of the aluminium alloy extruded pipe mold of heavy caliber of the present invention two floor seam chambers.
The specific embodiment
As shown in Figure 1, 2, the aluminium alloy extruded pipe mold of heavy caliber of the present invention comprises shunting hole, seam chamber, when the pipe of extruding Φ 508, the number of shunting the hole is increased to 10, the shunting bridging is narrow, and seam is easy, shunts hole entrance chamfering to reduce the pressure that brings because of shunting hole number increase; Reduce the degree of depth of seam chamber, increase simultaneously by two floor seam chambers, the seam chamber degree of depth is generally 10-15mm, position corresponding to hole far shunted in the position that bridge location is corresponding, two release chambeies, floor seam chamber, two floor seam chambers from close to a little, general 3-5mm, crossing closely can affect the Surface of profile quality; The empty cutter degree of depth under core rod is reduced to 15mm, does ramped shaped, to reduce the lifting surface area of core rod, guarantee the intensity of core rod; Counterdie work band separately, part corresponding to shunting hole, the work belt length is a little, general 10-15mm, the part ratio shunting short 3-5mm of part corresponding to hole that bridge location is corresponding, if wall thickness is thicker, the seam difficulty, the work band of the part that the shunting hole is corresponding also can do to hinder the angle increases seam, hinders the angle and is generally 1.5 ° of left and right.
Operation principle: pipe patrix intensity is minimum, bridge often occurring splits and causes mould to be scrapped, the present invention has taked two measures for increasing patrix intensity: 1. the degree of depth that has reduced the seam chamber, be equivalent to reduce the height of core rod, core rod stablizes more that under 2. core rods, the empty cutter degree of depth shoals, and the core rod lifting surface area is less.But when these two measures increase mould strength, also reduced welding quality.In order to increase welding quality, also taked two measures: 1. increase by two floor seam chamber 2. counterdie work bands and do and hinder the angle, these two measures have all increased the pressure of counterdie seam chamber, have guaranteed welding quality, therefore the present invention in order to extend the life-span of mould, has transferred to the center of gravity of seam on counterdie.
The above embodiment is described the preferred embodiment of the present invention; be not that scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; various distortion and improvement that the common engineers and technicians in this area make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
Claims (3)
