Abstract
The utility model discloses a microchannel aluminum flat tube extrusion die, include die down, lower die comprises a plurality of die units, is equipped with nib and locating hole on the die unit. The utility model discloses simple structure replaces die under original full wafer through using the synthetic die down of a plurality of die unique tuples, and when the nib of having solved current microchannel aluminum flat tube extrusion die damaged, the whole die down that needs to be changed caused problem extravagant and the complementary modulus cycle length.
Description
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of microchannel aluminium flat conduit extrusion die.
Background technology
In aluminium extrusion processing industry, microchannel aluminium flat conduit extruding difficulty is higher.For microchannel aluminium flat conduit extrusion die, because the cross section of microchannel aluminium flat conduit is all very little, therefore often only can not squeeze a hole, need crowded four holes or six holes (having at most 10 holes).For the mould that upper and lower mould splits, multiple nib is arranged on the lower matrix of counterdie.The upper and lower mould used at present is separated the microchannel aluminium flat conduit extrusion die coordinated and has a lower matrix, lower matrix has six nibs.Find after deliberation, existing lower diaphragm is as a whole, when wherein there being a nib to damage, just needing to change whole lower matrix, not only causing waste but also make the cycle of complementary modulus there occurs larger prolongation.
Summary of the invention
When nib for existing microchannel aluminium flat conduit extrusion die damages, need to change whole lower matrix, cause waste and the problem of complementary modulus cycle length, the utility model proposes a kind of microchannel aluminium flat conduit extrusion die.
The technical scheme that the utility model adopts specifically is achieved in that
The utility model provides a kind of microchannel aluminium flat conduit extrusion die, comprises lower matrix, and lower matrix is made up of multiple matrix unit, and matrix unit is provided with nib and locating hole.
In order to better fixed die blade unit, matrix unit alignment pin is fixed.
Further, nib is round rectangle.
Further, lower matrix is circular.
Further, the quantity of matrix unit is 6.
The utility model structure is simple, lower matrix is become to replace matrix under original full wafer by using multiple matrix unit combination, when solving the nib damage of existing microchannel aluminium flat conduit extrusion die, need to change whole lower matrix, cause waste and the problem of complementary modulus cycle length.
Accompanying drawing explanation
Fig. 1 is the structure chart of lower matrix.
Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail detailed description of the invention of the present utility model below in conjunction with accompanying drawing, make above-mentioned and other object of the present utility model, Characteristics and advantages will be more clear.Deliberately do not draw accompanying drawing in proportion, focus on purport of the present utility model is shown.
As shown in Figure 1, a kind of microchannel aluminium flat conduit extrusion die, comprises multiple matrix unit 1, and each matrix unit 1 is provided with nib 2 and locating hole 3, and multiple matrix unit combination forms a lower matrix for extrusion die.The quantity of the locating hole of each matrix unit is 2, alignment pin can be used to pass locating hole 3 and be fixed, for convenience detach.The shape of lower matrix can be circular, and nib is round rectangle, and each lower matrix is formed by 6 matrix unit combination.
The utility model structure is simple, lower matrix is become to replace matrix under original full wafer by using multiple matrix unit combination, when solving the nib damage of existing microchannel aluminium flat conduit extrusion die, need to change whole lower matrix, cause waste and the problem of complementary modulus cycle length.
