Abstract
The utility model relates to a kind of aluminium flat conduit end necking die, comprises die ontology, and described die ontology middle part low side has little triangle through hole, and the top of described little triangle through hole is formed with the second fillet; The top that is positioned at little triangle through hole is also provided with large triangle through hole, and the top of described large triangle through hole is formed with the first fillet, and two large triangle through holes are symmetrically distributed in the rear and front end of die ontology; And being formed with the 3rd fillet being oppositely arranged in the bottom of die ontology, the outer end of described the 3rd fillet is extended with reducing working face.The utility model compact conformation, reasonable, easy to make, by reducing working face being set in die ontology bottom, pushes its port to aluminium flat conduit, completes required reducing size, and operating efficiency is high, and cost is low.
Description
Technical field
The utility model relates to necking die field, especially a kind of aluminium flat conduit end necking die.
Background technology
At present, the condenser of air conditioning for automobiles, domestic air conditioning is all that condenser is completed by many flat tubes and header erection welding with aluminium flat conduit, and air-conditioning producer, for optimizing product, raises the efficiency, and has done very large improvement in production technology.This just needs aluminium flat conduit end to carry out reducing processing, and using the position of reducing as reference for assembling, the production efficiency of condenser product and product quality all can improve a lot, and product quality is guaranteed.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of aluminium flat conduit end necking die rational in infrastructure, thereby can complete easily the reducing of aluminium flat conduit end, meets instructions for use, and operating efficiency is high.
The technical scheme that the utility model adopts is as follows:
A kind of aluminium flat conduit end necking die, comprises die ontology, and described die ontology middle part low side has little triangle through hole, and the top of described little triangle through hole is formed with the second fillet; The top that is positioned at little triangle through hole is also provided with large triangle through hole, and the top of described large triangle through hole is formed with the first fillet, and two large triangle through holes are symmetrically distributed in the rear and front end of die ontology; And being formed with the 3rd fillet being oppositely arranged in the bottom of die ontology, the outer end of described the 3rd fillet is extended with reducing working face.
Further improvement as technique scheme:
The radius of described the second fillet is R0.5-R1.5;
The radius of described the second fillet is R0.9;
The radius of described the second fillet is R1.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, reasonable, easy to make, by reducing working face being set in die ontology bottom, pushes its port to aluminium flat conduit, completes required reducing size, and operating efficiency is high, and cost is low.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is the full sectional view along A-A cross section in Fig. 1.
Fig. 3 is the top view of Fig. 1.
Wherein: 1, die ontology; 2, the first fillet; 3, large triangle through hole; 4, the second fillet; 5, little triangle through hole; 6, the 3rd fillet; 7, reducing working face.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1, Figure 2 and Figure 3, the aluminium flat conduit end necking die of the present embodiment, comprises die ontology 1, and die ontology 1 middle part low side has little triangle through hole 5, and the top of little triangle through hole 5 is formed with the second fillet 4; The top that is positioned at little triangle through hole 5 is also provided with large triangle through hole 3, and the top of large triangle through hole 3 is formed with 2, two large triangle through holes 3 of the first fillet and is symmetrically distributed in the rear and front end of die ontology 1; And the outer end that is formed with the 3rd fillet 6, the three fillets 6 that are oppositely arranged in the bottom of die ontology 1 is extended with reducing working face 7.
The radius of the second fillet 4 is R0.5-R1.5.
The radius of the second fillet 4 is R0.9.
The radius of the second fillet 4 is R1.
Operation principle:
Flat tube is pushed the width of flat tube by the reducing working face 7 of necking die before cutting, thereby makes flat tube end that deformation occur, and meets corresponding reducing dimensional requirement, and ensures that, in the time that flat tube is broken in cutting, the incision of flat tube does not have burr.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of amendment.
