Reasons for choosing copper pipes and treatment methods for flaring and cracking
Copper tube is a non-ferrous metal with a close relationship with human beings. It is widely used in electrical, light industry, machinery manufacturing, construction industry, defense industry and other fields. It is second only to aluminum in the consumption of non-ferrous metal materials in China.
Copper tubes are widely used and used in the electrical and electronic industries, accounting for more than half of the total consumption. For various cables and wires, windings of motors and transformers, switches and printed circuit boards, etc .; in the manufacture of machinery and transportation vehicles, it is used to manufacture industrial valves and accessories, meters, plain bearings, molds, heat exchangers and pumps In the refrigeration industry, it is widely used in refrigerant circulation pipes, air-conditioning connection pipes for indoor and outdoor air-conditioning units; in the chemical industry, it is widely used in the manufacture of vacuum appliances, retorts, and brewing pots; in the defense industry, it is used to make bullets and artillery , Gun parts, etc., for every 1 million rounds produced, 13-14 tons of copper are required; in the construction industry, it is used for various copper water pipes, pipe fittings, decorative devices, etc.
There are many types of copper pipes, and there are many consumers who choose copper pipes among many copper pipes. So how attractive is it to be so popular? Here are some reasons to choose it. First of all, practicality is a reason for consumers to choose. Its installation process is very convenient, it does not need to occupy a lot of places and does not need to perform complex welding. The important thing is that it can meet different requirements, so it is practical, which is a feature of it. Secondly, it's cheap. This is the reason why consumers choose copper pipes. It is cheaper than other pipes with the same purpose, and because its installation process is relatively simple, this process has saved a lot of costs. The price is very cheap.
The copper pipe connection is very rugged, making it of practical value. Due to the variety of pipes on the market, the interface fittings are copper pipes. Even if some pipe fittings cannot use copper fittings, they are also connected to the faucet or have copper fittings. However, if the thermal expansion and contraction of the physical and mechanical properties of pipes and fittings such as copper pipe fittings are very different due to different materials, the natural connection will naturally be subject to additional challenges. Therefore, the connection of brass and copper accessories will greatly improve the robustness.
Definition of copper pipe flaring: a stamping process that expands the opening of hollow copper pipe outwards. Copper pipe flaring belongs to the shrinking procedure in the processing of copper pipes. The copper pipe flaring includes the copper pipe flaring equipment, operation and technical requirements. Copper tube flaring is also flawed, for example, copper tube flaring is cracked. The cause of the copper tube flaring can be attributed to two points, which will be mentioned in the following introduction. Since the copper pipe flaring has cracked, it should be found a solution. The following section introduces the "flared copper pipe flaring and cracked copper pipe flaring".
Equipment and operating requirements for copper pipe flaring?
1. Open the air source to ensure that the air pressure is (0.3 ~ 0.7) MPa.
2. According to the requirements of the drawing, select the appropriate expansion die, clamping block, and adjust the stroke of the punch to meet the requirements of the drawing. Install the expansion and contraction die and clamping block on the expansion and contraction machine, adjust the tooling and punch positions so that their centers are in a straight line.
3. The copper pipe is dipped in volatile oil before the flaring or shrinking.
