Extruding drawing mould of the present utility model, the quality of seam is high, and within the pipe out of roundness obtained can reach 0.02mm, surface smoothness is high, need not process in two roads again, just can use.In addition, extruding drawing mould of the present utility model, can increase to 7 tons by the die life of tradition about 2 tons, even more, greatly reduces production cost, the volume production of successful pipe.
Should be understood that within the scope of the utility model, above-mentioned each technical characteristic of the present utility model and can combining mutually between specifically described each technical characteristic in below (eg embodiment), thus form new or preferred technical scheme.As space is limited, tiredly no longer one by one to state at this.
Accompanying drawing explanation
Fig. 1 shows existing structure of extrusion schematic diagram.
Fig. 2 is the structural representation shunting bridge portion in existing extrusion die.
Fig. 3 is extruding drawing mould structural representation of the present utility model.
Fig. 4 is the structural representation shunting bridge portion in mould of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.
Comparative example
As shown in Figure 1, for the structural representation of the extrusion die of existing pipe, comprise male model 1 and master mold 2, wherein, male model 1 is provided with shunting bridge 3 and core rod 4, described master mold 2 is provided with bonding container 8 and nib 5, is work strip 6 between bonding container 8 and nib 5, and bonding container 8 and work strip 6 junction are straight structure.
Described core rod 4 is arranged on described male model 1 center.
Described shunting bridge 3 is arranged on charging place of described male model 1.As shown in Figure 2, be provided with tap hole 7 inside described shunting bridge 3, by tap hole 7, stream be divided into multiply.After each stock material stream converges and carries out seam in bonding container 8, to be extruded by nib 7 through work strip 6 and obtain pipe section bar.
Verified, adopt this existing extrusion die, be difficult to solve seam line strength and out of roundness problem, interior hole circle ovality is very large, and coarse also the failing on surface reaches requirement, and most of pipe product needed relies on CNC to hole further just can reach requirement.
Embodiment
As shown in Figure 2, the extruding drawing mould of pipe of the present utility model, structure is substantially identical with the extrusion die of comparative example, also comprises male model 1 and master mold 2, and wherein, male model 1 is provided with shunting bridge 3 and core rod 4, described master mold 2 is provided with bonding container 8 and nib 5.
Difference is, arranges connected one-level work strip 9 and secondary work band 6 between described bonding container 8 and described nib 5, and the junction between wherein said bonding container 8 and described one-level work strip 9 is set to infundibulate.
As shown in Figure 4, be provided with tap hole 7 inside shunting bridge 3, by tap hole 7, stream be divided into multiply.After each stock material stream converges and carries out seam in bonding container 5, carry out second time seam at funnel place, make the more firm seam of aluminium material together, ensure welding quality.After through one-level work strip 9 preformed, then through secondary work band 6 controlling dimension and surface accuracy, improve fineness, extruded by nib 7 afterwards and obtain pipe section bar.
