Problems solved by technology

[0002] When the existing air conditioner is installed, the quick connector exposed to the outdoor unit is closed by a stop valve, and the existing stop valve usually adopts two connection methods, one is welded and sealed, and the other is a soft seal plus a hard seal. The performance is far superior to the former, but the existing die is usually installed with a vise, and the die is used to extrude to achieve the hard seal of the joint, and the extruding die is usually easy to produce burrs on the outer wall of the joint, which is easy to scratch Injury to the palm, it is necessary to propose a molding device for the copper-aluminum interface connection of the shut-off valve to solve the above problems

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] The present invention provides such Figure 1-7 The production process and device for the copper-aluminum interface of the stop valve include the following steps: Step S1: forming a copper joint by casting copper liquid; step S2: forming an aluminum joint by casting aluminum liquid; step S3: converting the copper joint obtained in step S1 . The aluminum joints obtained in step S2 are socketed through a socketing device to form a copper-aluminum joint gr...

Abstract

The invention discloses a stop valve copper-aluminum connector manufacturing process and device, and belongs to the field of stop valve production. The stop valve copper-aluminum connector manufacturing process and device comprise the following steps that S1 a copper connector is formed through molten copper casting; S2 an aluminum connector is formed through molten aluminum casting; and S3 the copper connector obtained in the step S1 and the aluminum connector obtained in the step S2 are connected in a sleeving mode through a sleeving device, and a copper-aluminum connector set is formed. Compared with the prior art, the manufacturing process and the device have the advantages that through a high-pressure gas stamping device, an copper-aluminum pipe is automatically pressed and extruded, and hard sealing of the copper-aluminum connector is achieved; when the high-pressure gas stamping device carries out stamping die pressing, airtightness detection is carried out on the interior of the copper-aluminum pipe at the same time, burrs are cut when the copper-aluminum pipe is detected to be qualified, work is stopped when the copper-aluminum pipe is detected to be unqualified, and selection of qualified products and defective products is achieved.

Description

technical field [0001] The invention belongs to the technical field of shut-off valve production, and in particular relates to a production process and a device for a copper-aluminum interface of a shut-off valve. Background technique [0002] When the existing air conditioner is installed, the quick connector exposed to the outdoor unit is closed by a stop valve, and the existing stop valve usually adopts two connection methods, one is welded and sealed, and the other is a soft seal plus a hard seal. The performance is far superior to the former, but the existing die is usually installed with a vise, and the die is used to extrude to achieve the hard seal of the joint, and the extruding die is usually easy to produce burrs on the outer wall of the joint, which is easy to scratch Injury to the palm, it is necessary to propose a molding device for connecting the copper-aluminum interface of the shut-off valve to solve the above problems.
