Abstract
The utility model relates to an air conditioner preparation field, more specifically says, an aluminum pipe heat exchanger horn mouth shaping sleeve that the aluminum pipe heat exchanger that relates to an air conditioner used in manufacturing process. Including horn mouth formed part that is located the front end and the axle sleeve that is located the rear end, the horn mouth formed part includes the guidance part, the guidance part is connected with the tip of toper flaring portion, and the guidance part front end is equipped with tip toper spigot surface forward. The beneficial effects of the utility model are that: among the aluminum pipe heat exchanger horn mouth shaping sleeve, the front end is the guidance part in the horn mouth formed part, and the guidance part front end is equipped with tip toper spigot surface forward, ensures that the horn mouth is not eccentric, with the guidance part be connected for toper flaring portion to the tip of toper flaring portion is connected with the guidance part, is connected column portion with toper flaring portion main aspects, and it is bad to solve the flaring shaping.
Description
Technical field
The utility model relates to air-conditioning preparation field, more particularly, relates to a kind of aluminum pipe heat exchanger horn mouth forming sleeve that a kind of aluminum pipe heat exchanger of air-conditioning is used in manufacturing process.
Background technology
At present, in production overhead automobile air conditioning system enterprise, major part is all adopt copper screwed tube heat exchanger, according to the needs of the light-weighted development of car air-conditioner, adopts aluminium heater to replace original copper screwed tube heat exchanger.
Air-conditioning aluminum pipe heat exchanger is carrying out in the process of producing, there is one enlarging operation, so-called enlarging operation is exactly process horn mouth in the end of air-conditioning aluminum pipe heat exchanger aluminum pipe, the horn mouth at mouth of pipe place mainly plays in follow-up welding sequence holds solder, avoids the effect that solder runs off when welding.The welding quality of aluminium heater depends on the one-time formed quality of horn mouth after expand tube, and the bell-mouthed quality of aluminium heater depends on horn mouth mould, it is shaping that original copper heat exchanger horn mouth mould is used for aluminium heater horn mouth, produce larger eccentric force in horn mouth forming process, horn mouth compact dimensions, horn mouth centre-to-centre spacing uniformity are poor.
Summary of the invention
Easy to be partially swollen in order to overcome aluminium heater horn mouth, and horn mouth Forming Quality difference etc. defect, the utility model provides a kind of aluminum pipe heat exchanger horn mouth forming sleeve, effectively can ensure aluminium heater horn mouth Forming Quality.
For achieving the above object, the utility model provides following technical scheme: a kind of aluminum pipe heat exchanger horn mouth forming sleeve, comprise the horn mouth profiled member being positioned at front end and the axle sleeve being positioned at rear end, described horn mouth profiled member comprises guidance part, described guidance part is connected with the small end of taper expansion mouth, and guidance part front end is provided with small end tapered guide surface forward.
The large end of described taper expansion mouth is connected with columnar part.
Also comprise and be arranged at inner suit hole, described suit hole is through hole.
The beneficial effects of the utility model are: in aluminum pipe heat exchanger horn mouth forming sleeve, and in horn mouth profiled member, front end is guidance part, and guidance part front end is provided with small end tapered guide surface forward, guarantee that horn mouth is not eccentric; What be connected with guidance part is taper expansion mouth, and the small end of taper expansion mouth is connected with guidance part, is connected columnar part with the large end of taper expansion mouth, solves flare formation bad.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, horn mouth profiled member; 2, suit hole; 3, tapered guide surface; 4, guidance part; 5, taper expansion mouth; 6, columnar part; 7, axle sleeve.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of aluminum pipe heat exchanger horn mouth forming sleeve, comprise the horn mouth profiled member 1 being positioned at front end, the axle sleeve 7 being positioned at rear end, described horn mouth profiled member comprises guidance part 4, described guidance part 4 is connected with the small end of taper expansion mouth 5, and guidance part 4 front end is provided with small end tapered guide surface 3 forward.
Described taper expansion mouth 5 greatly end is connected with columnar part 6.
Also comprise and be arranged at inner suit hole 2, described suit hole 2 is through hole.
In aluminum pipe heat exchanger horn mouth forming sleeve, in horn mouth profiled member 1, front end is guidance part 4, and guidance part 4 front end is provided with small end tapered guide surface 3 forward, guarantees that horn mouth is not eccentric; What be connected with guidance part 4 is taper expansion mouth 5, and the small end of taper expansion mouth 5 is connected with guidance part 4, is connected columnar part 6 with the large end of taper expansion mouth 5, solves flare formation bad, and suit hole 2 and the diametric fit of expander roll, be lowered into mould offset distance.
