| What are the main characteristics of stainless steel elbow machine?
Stainless steel elbow machine has very lively chemical properties at high temperature, small thermal conductivity, heat capacity is big, in the production of stainless steel elbow, when welding the pipe weld appear easily oxidation and the problems such as air pollution, the serious influence welding quality, therefore, must be used when welding the stainless steel elbow pipe internal charge gas to solve the problem of internal weld of high temperature oxidation.
At present, the domestic steel elbow forming manufacturing commonly used processing methods are: casting method, stamping stamping method, welding method, cold and hot pushing method. Stamping stamping stamping method ---- the method of bending the heated tube billet with the die on the elbow machine. This method was first used in the bending process of tube elbow, and has been widely used in the production of elbow. However, the wall thickness of the elbow produced by this method is uneven and the appearance quality is poor. When processing large elbow, the mold manufacturing cost is higher.
Process specification of stainless steel elbow: this process is suitable for the manufacture of carbon steel butt welded long radius and short radius elbow made of hot push.
Stainless steel elbow machine from the bottom to the finished product process matters needing attention: adjust the center height of the mandrels. And keep consistent with the center of the push head of the push machine. Adjust the front and back stroke limits of the push machine. Adjust the working pressure and propulsion speed of the direct push machine. Check whether the hydraulic, electrical and cooling systems work normally and whether the action is sensitive. For lubrication, a thin and uniform layer of graphite powder is applied to the inner wall of the pipe. Start the pump, intermediate frequency power supply, adjustment of intermediate frequency power, and match the advancing speed, push the machine before the mandrel rod fixture on the tube billet slowly forward, tube billet by induction heating ring, the pipe under the action of thrust and under high temperature condition began expanding, bending forming and take off the plug, to complete a bending forming process.
In addition to the production of elbow machine, our company also produces tee machine, medium frequency pipe bending machine, pipe bending machine, elbow machine and other pipe fitting equipment.
