Description

Technical Field

[0001] This utility model relates to the field of refrigerant distributor processing technology, and in particular to a hot-stamped copper profile for manufacturing refrigerant distributors. Background Technology

[0002] A refrigerant distributor is a crucial device in a refrigeration system. Its main function is to distribute refrigerant from the evaporator to the condenser and evaporator to achieve balanced operation of the refrigeration cycle. Figure 1 As shown, there is a refrigerant distributor 1, which includes a main body 11 and a branch pipe 12. The main body 11 is directly machined by cutting a copper rod, which results in serious material waste and low processing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a hot-stamped copper profile for manufacturing refrigerant distributors, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A hot-stamped copper profile for manufacturing a refrigerant distributor includes a flow divider and a flow merger integrally formed and connected; the flow divider includes an annular inclined portion, a clamping cylindrical portion and a frustum flow divider portion, one end of the clamping cylindrical portion is connected to the annular inclined portion and the other end is connected to the frustum flow divider portion; the flow merger portion is cylindrical and one end is connected to the frustum flow divider portion.

[0006] Preferably, the angle between the inclined surface of the annular bevel and the top surface of the clamping cylindrical part is 5°-15°, which facilitates the subsequent drilling and installation of the diversion pipe.

[0007] Preferably, the thickness of the clamping cylindrical part is not less than 2cm, which facilitates clamping and subsequent rotary turning.

[0008] Preferably, an annular platform is provided at the connection between the frustum-shaped flow divider and the clamping cylindrical part to allow for machining allowance and facilitate subsequent clamping and machining.

[0009] Compared with the prior art, the hot-stamped copper profile of this application for manufacturing refrigerant distributors has the following advantages:

[0010] This invention features a novel hot-stamped copper profile semi-finished blank designed based on the structure of the refrigerant distributor, solving the problems of excessive material waste and low efficiency associated with direct cutting of copper rods. The invention includes an annular beveled section matching the distribution pipe, a clamping cylindrical section for easy chuck and worktable mounting, and a confluence section for convenient subsequent machining. The clamping cylindrical section can be held in place by the chuck, allowing for rotary turning of other parts with significantly less cutting material than in existing technologies using direct copper alloy rods, thus greatly saving material and improving processing efficiency.

[0016] The following detailed description illustrates the specific implementation method:

[0017] Example 1

[0018] like Figure 2-4 As shown in the figure, this embodiment demonstrates a hot-stamped copper profile for manufacturing a refrigerant distributor, comprising a shunt section 2 and a manifold section 3 integrally formed and connected. Specifically, this product is a semi-finished blank of a refrigerant distributor, which is formed from a continuously cast copper alloy rod through rolling and hot forging, and subsequently requires rotary turning and drilling processes for finishing. The shunt section 2 includes an annular inclined section 21, a clamping cylindrical section 22, and a frustum-shaped shunt section 23. One end of the clamping cylindrical section 22 is connected to the annular inclined section 21, and the other end is connected to the frustum-shaped shunt section 23. Specifically, the annular inclined section 21 is connected to the shunt pipe 12 after subsequent clamping processing. The manifold section 3 is cylindrical, with one end connected to the frustum-shaped shunt section 23. In actual processing, the cylindrical section 22 can be clamped by a chuck, and other parts can be rotary turned. The cutting amount is much smaller than that of the cutting process using copper alloy rods directly in the prior art, improving processing efficiency and greatly saving materials.
