Chiho Hebei Industry GB stamping elbow cold stamping and hot stamping points two, is usually cold stamping or hot stamping equipment according to the material properties and the ability to cold extrusion process is to use a dedicated elbow elbow forming machine, the tube into the outer mold, after the upper and lower mold clamping, push in the push rod, tube along the inner and outer dies reserved space movement forming process is completed. stamping elbow was first used in mass production without elbow joints forming process, at present, has been hot extrapolation or replaced by other forming process in the production of common specifications elbow, but in some of elbow due to a small number of production, the thickness is too thick or products still using special requirements. elbow and elbow using stamping outer diameter equal to the tube, using a press in a mold direct compression molded Before stamping, tube placed on the lower mold, the inner core and the end die stamping elbow tube into the plant, the downward movement of the upper mold starts pressing, bound by the outer mold and the inner mold supporting role so hot compared with the elbow shaped push technology, visual quality not as good as the former stamping; Stamping When outer arc shaped bend in tension, no other parts to compensate excess metal stamping elbow 180, so the wall thickness of the outer arc of about 10% thinner. However, due to the production of a single piece and is suitable for low-cost features, it is used for stamping elbow craft small batch manufacturing thick-walled elbow elbow GB stamping Features: 1, temperature and pressure, good flexibility, heat resistance, and its performance is higher than other thermal plastic pipe installation easy Good suitable for floor heating systems, recyclability .2, P GB stamping elbow pipe has its excellent impact strength, melt welding and mechanical connections, better than PB-PP-R thermal conductivity of stainless steel stamping bends elbow pipe head is in a stamping elbow, with different angles and content of the elbow, full of a certain competitive advantage, buy stainless steel elbow went to Hebei to Chiho Industry. Stainless steel stamping elbow has excellent corrosion resistance. Rugged stainless steel thin oxide film so that all water quality in stainless steel has excellent corrosion resistance, even underground also has excellent corrosion resistance. So it is suitable for all kinds of water quality, in addition to sterilization, no control of water quality, but also no corrosion and excessive exudate, can keep the water clean health, to prevent secondary pollution, can withstand up to 30 meters per second The high water shock. High strength stainless steel elbow connector, anti-vibration, the joints do a one-time strong, to avoid the "union" of the possibility of stamping elbow loose, fast and convenient construction, avoiding site welding operations and threading operations, stainless steel elbow long service life. Field corrosion test data indicate, the service life of up to 100 years of stainless steel elbow, stainless steel elbow virtually no maintenance, and therefore its cost performance is very good, low cost operating life, significant economic benefits. Stainless steel elbow-site installation is very convenient. Installation takes only welded pipe or wire sets 1/3, shorten the duration and cost, to avoid water leakage from happening. In connection elbow in a certain way and conducted in accordance with the principle of control and use, with good installation features and values, the need to constantly use certain way to use.
