A hand-held spray gun copper pipe welding device for air-conditioning production

Abstract

One or more embodiments of this specification provide a hand-held spray gun copper pipe welding device for air-conditioning production, including: a holding handle, a rear positioning sleeve at the rear end, and a front guide groove at the front end. The front side is provided with a front-end fixing frame; the vertical sliding seat is fitted and slidably arranged in the middle of the vertical chute, the rear side of the vertical sliding seat is provided with a linkage rack, and the front of the vertical sliding seat A C-shaped snap-fit ​​frame is arranged on the side; the pressing handle is arranged below the gripping handle. In the present invention, when the C-shaped fastening frames can be fastened together by holding the pressing handle tightly, the copper pipe joint can be snapped into it, and it can be heated and welded through the flame spraying of the outer ring of flame spraying head, and the heating is more uniform. At the same time, the clamping structure is symmetrically arranged on both sides of the C-type buckle frame, and the copper tube can be clamped and pushed to the connection while the pressing handle is held tightly, so that the connection of the copper tube is more stable during welding, and the use is more convenient. flexible.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of air-conditioning production, and in particular to a hand-held spray gun copper pipe welding device for air-conditioning production. Background technique [0002] Air conditioning refers to equipment that uses manual means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure, generally including cold source / heat source equipment, cold and hot medium transmission and distribution systems, and terminal devices. And other auxiliary equipment, mainly including refrigeration main engine, water pump, fan and pipeline system, and the internal and external heat exchange structure is generally connected through copper tubes. The main refrigeration components such as heat exchangers, valves, and compressors are connected through the process. In the production of air conditioners, copper pipes such as compressors a...

Problems solved by technology

[0003] The applicant found that in the production and processing of air conditioners, when the copper pipes inside are welded, the joints of the copper pipes are generally heated at high temperature and the solder is melted to weld the copper pipes together, while an ordinary flame gun is used to heat the copper pipes During welding, the flame gun can only heat the copper tube in one direction, and it is necessary to constantly adjust the position and direction of the spray flame to ensure uniform heating of the copper tube. Before the pipe is welded, it is necessary to insert the joint of one copper pipe into the joint of another copper pipe to temporarily fix it by friction force. However, when welding and heating, due to the thermal expansion of the copper pipe, the joint of the copper pipe is easy to fall off, which affects the quality of welding. and efficiency
