Continuous machining device for necking and flaring connecting parts of automotive air conditioner metal fittings

Abstract

The invention discloses a continuous machining device for necking and flaring connecting parts of automotive air conditioner metal fittings. The continuous machining device comprises a rack, a working table located on the rack, a fixture fixed to the working table and used for fixing the automotive air conditioner metal fittings to be machined and a vibration feed table used for conveying the automotive air conditioner metal fittings to be machined. A feeding mechanism located on one side of the fixture is arranged on the working table. Compared with the prior art, the continuous machining device shrinks the ends of the barrel-shaped automotive air conditioner metal fittings into necking structures through the cold pressing method and conducts direct punching on the necking parts into flared connecting parts. The traditional welding forming method is changed. The machining process is shortened. The flared connecting parts facilitate mounting of branch pipes. Meanwhile, the branch pipes can be fixed by necking the connecting part. The product quality and machining efficiency are improved. Continuous machining can be realized.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of processing equipment for automobile air-conditioning metal fittings, in particular to a continuous processing device for shrinking and expanding joints of automobile air-conditioning metal fittings. [0003] 【Background technique】 [0004] In the process of processing metal parts of automobile air conditioners, in order to form a constriction on the cylindrical metal element and form a connection part at the constriction, the connection part is used to match the branch pipe with a smaller diameter. [0005] In the prior art, its processing such as figure 1 As shown, a cylindrical metal fitting is welded with an outer cover a, and a columnar connecting part b for connection is welded on the outer cover a. This kind of processing method cannot be formed in one step, which includes cutting and connecting the outer cover. Hole cutting and connection part welding are extremely complicated, resulting i...

Problems solved by technology

[0005] In the prior art, its processing such as figure 1 As shown, a cylindrical metal fitting is welded with an outer cover a, and a columnar connecting part b for connection is welded on the outer cover a. This kind of processing method cannot be formed in one step, which includes cutting and connecting the outer cover. Hole cutting and connecting part welding are extremely complicated, resulting in low work efficiency, and this kind of columnar connecting part needs to be welded and fixed after the branch pipe c is installed, and it is impossible to use the connecting part to shrink the mouth to fix the branch pipe. purpose, and when the diameter of the columnar joint is relatively close to the diameter of the branch pipe, the installation of the branch pipe is extremely inconvenient
