A hole-enlarging processing device for air-conditioning refrigeration copper pipes

Abstract

The invention discloses a pore-broadening processing device for a refrigerating copper tube of an air conditioner. The pore-broadening processing device comprises a pore-broadening table body and a pore-broadening adjusting column. The pore-broadening adjusting column is movably connected to the pore-broadening table body, a reamer is arranged on the pore-broadening table body in a penetrating manner, an annular groove is formed in the reamer, an annular connecting seat is connected to the annular groove in a sleeving manner, and first springs are fixedly connected to two sides of the annularconnecting seat; when the copper tube is further processed, all needed tools are placed on one device, so that the tools can be directly operated during processing; when the copper tube is processed,a compaction plate clamping the copper tube only can be placed on the ground, and a triangular supporting plate can play a stable supporting role. By elastically connecting the reamer, the reamer is pressed downward only and rotated simultaneously when the copper tube is polished, so that the pore-broadening processing device polishes and operates the copper tube conveniently.

Description

technical field [0001] The invention relates to the technical field of mechanical processing devices, in particular to a hole-expanding processing device for air-conditioning refrigeration copper pipes. Background technique [0002] The air conditioner has two connecting pipes of larger and smaller sizes. The thick one is called the large pipe, and the thin one is called the small pipe. It is used to connect the internal and external units, so that the internal and external units form a closed system. The refrigerant can circulate in the internal and external units. Under normal circumstances, the large pipe uses gaseous refrigerant, and the small pipe carries liquid refrigerant. As for which one goes in and which goes out, it depends on the cooling and heating modes of the air conditioner. In the cooling mode, copper pipes are used to connect the air conditioner. ; In order to achieve the purpose of easy operation, but it still has the following disadvantages in actual use:...

AI Technical Summary

Problems solved by technology

[0003] 1. In the cooling mode, the refrigerant enters the internal unit from the external unit through the small tube, and returns to the external unit through the large tube. For the copper tube connection, the copper tube needs to be further processed. In the existing technology, the copper tube Processing requires multi-step operations, and more tools are required, which can easily cause loss of tools and incomplete tools when used;

[0004] 2. Copper can change its shape, because copper pipes can be bent and deformed, and copper pipes can often be made into elbows and joints. When making joints, copper pipes generally need to be reamed into bell mouths for convenience. The connecting pipe is more tightly connected. During the reaming process, the operator needs to clamp the splint with one hand and rotate the reamer with one hand. If you don’t pay attention, it will easily cause the reaming to be rough or cause the reaming to deviate;

[0005] 3. When reaming the copper pipe, it is necessary to polish the interface of the copper pipe to better ream the hole. In many cases, this step is directly omitted for the sake of simple operation, resulting in the interface of the copper pipe not being smooth enough.
