Example Embodiment

[0015] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] See Figure 1 to Figure 3 , A metal pipe bell mouth processing equipment, used for processing the bell mouth of the connecting pipe of the air conditioner inner and outer machine, especially suitable for the connecting pipe of copper alloy material. It includes a fixing device 1, a necking punch 2 and a flaring punch 3.

[0017] See figure 1 The fixing device 1 is composed of two parts, with a clamping space 11 for clamping the metal tube in the middle. After the two parts of the fixing device 1 are combined, the front part of the fixing device 1 has a tapered groove 12 exposing the front end of the metal tube. In order to facilitate manual operation of the metal tube and adjust the exposed length of the front end of the metal tube, the rear part of the fixing device 1 has a tapered groove 13 exposing the rear end of the metal tube.

Abstract

The invention provides processing equipment for a horn mouth of a metal tube. The processing equipment comprises a fixing device used for clamping and fixing a metal tube, a throat punch used for necking certain end part of the metal tube, a flaring punch used for flaring and forming another end of the metal tube, wherein the front part of the fixed device is provided with a tapered slot which is exposed at the front end of the metal tube; the throat punch is provided with an arc slot, the diameter of the arc slot is not less than the outer diameter of the metal tube, the front end of the flaring punch is coaxially provided with a flanging section and a flaring section from front to back, the flanging section is a forwards protruding tip, and the flaring section is a conical platform matched with the tapered slot. Compared with the prior art, according to the processing equipment provided by the invention, the parts can be greatly reduced, the process of flanging and flaring and forming can be completed by the flaring punch, the processing procedures can be shortened, the production efficiency can be greatly improved, and the reject ratio can be reduced.

Description

technical field [0001] The invention relates to a processing device for bell mouths of metal pipes, in particular to a processing equipment for processing bell mouths of connecting pipes of internal and external units of air conditioners. Background technique [0002] In the prior art, the processing equipment for processing the bell mouth of the connecting pipe of the internal and external units of the air conditioner has a complex structure, many parts, and many processing steps, resulting in low processing efficiency. For example, Chinese patent CN203973193U discloses a processing equipment for processing bell mouths of copper-aluminum composite pipes, which includes a base, a forming device, a flaring device and a power device, and the forming device includes a forming clamp, an end face cutting tool, a grinder, Cutter, necker, flanger and extruder, flaring device includes flaring clamp, flaring punch. When processing bell mouths for copper-aluminum composite pipes, the...
