Abstract

The invention provides a cooling pipeline aluminum branch pipe and a manufacturing method of the cooling pipeline aluminum branch pipe, and belongs to cooling system pipelines. An existing cooling pipeline branch pipe produced through stamping is poor in compressive strength and high in leakage rate. According to the method, a multi-way joint substrate is made of aluminum alloy profile produced through extrusion forming or aluminum alloy castings produced through pressure casting. When an output hole is machined, drilling is conducted through a drilling machine and a drill bit to machine out a basic hole firstly, then the drilling machine and a vertical milling cutter counter sinking are adopted to machine out a faucet part without replacing a clamping. When an input hole is machined, the lathe dog clamping drives a workpiece to rotate, drilling is conducted through the drill bit to machine out a basic hole, then the lathe and the vertical milling cutter counter sinking are adopted to machine out the faucet part without replacing the clamping. Counter sinking machining is conducted on the basic hole through a vertical milling cutter with the same diameter with the basic hole instead, the bottom of the basic hole is machined to be a flat bottom, boring processing is conducted on the input hole through a boring cutter, and medium circulation obstacle is removed. An input pipe and an output pipe are inserted into the input hole and the output hole and are fixed in a welding mode. According to the method, the multi-way joint substrate is high in strength and good in welding firmness, and the cutting machining hole is high in accuracy.

Description

technical field

[0001] The invention belongs to the technical field of refrigeration system pipelines, and in particular relates to a refrigeration pipeline aluminum branch pipe and a manufacturing method thereof. Background technique

[0002] The branch pipe of the refrigeration pipeline is a connection pipeline used to divide one medium input into two or more medium outputs in the refrigeration pipeline. Its structure is mainly to use three-way or multi-way connectors to connect round pipes. The multi-way joint of the existing branch pipe is made of copper pipe stamping. The manufacturing process is mainly to use a round pipe with a large diameter. The cylindrical die is inserted into the inner cavity of the circular tube at intervals and then punched with a punching machine, so that the pipe walls on both sides of the multiple cylindrical dies are sunken and then connected together to form multiple holes with the same diameter as the cylindrical die as the output ...

Embodiment Construction

[0017] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] like Figure 1~5 As shown, the present invention comprises an input pipe 1, two output pipes 3 and a multi-way joint 2 connecting the input pipe and the output pipe, the input pipe and the output pipe are respectively welded to the input hole and the output hole of the multi-way joint, and multiple The base body of the multi-way joint is made of extruded aluminum alloy profiles or die-cast aluminum alloy castings according to the length and size of the multi-way joint. The shape of the multi-way joint base is a drum-shaped cylinder with two parallel cylinders. On the plane, the input hole and the output hole are cut and formed on the base of the multi-way joint. Both the input hole and the output hole are provided with a section of socket, and the input pipe and the output pipe are inserted and welded to the corresponding socket.
