Abstract

The invention discloses a bell-mouth expansion clamping mold for pipe fittings, which comprises a movable mold with a first installation part and a fixed mold with a second installation part, a positioning guide device is arranged between the movable mold and the fixed mold, and One end of the mold cavity formed by the movable mold and the fixed mold is provided with a first bell mouth, and the other end of the mold cavity is provided with a second bell mouth. With such arrangement, the pipe fitting bell mouth clamping mold provided by the present invention can effectively solve the problem of cost waste and low replacement efficiency caused by the clamping mold in the prior art.

Description

technical field [0001] The invention relates to the technical field of pipe fitting processing, and more specifically relates to a pipe fitting flare expansion clamping die. Background technique [0002] In order to meet the needs of installation or use, some industrial pipe fittings usually need to expand their nozzles into a bell-shaped mouth. For example, in the production process of air conditioners, copper pipes or copper-aluminum pipes are used as the connecting pipes of air conditioners. Before the copper pipes or copper-aluminum pipes are installed in the air conditioner, they need to be expanded with a bell mouth. [0003] At present, in the mass production process of air-conditioning connecting pipes, the expansion of the bell mouth of the connecting pipe is usually clamped by the bell mouth clamping mold. Clamped in the mold cavity by the clamping film. Then, the nozzle part of the connecting pipe is stamped with a tapered punch, so that the nozzle part of the c...
