introduction： A method of forging and forming by using the superplasticity of certain metals under certain conditions。The plasticity of a metal is usually expressed in terms of elongation﹐Its value is generally less than40％。But under certain conditions, metals are superplastic﹐It is characterized by﹕Elongation can be increased by tens to hundreds of times﹐Up to2000％above﹔The flow stress is reduced to one tenth of the original﹔No work hardening。 Tensile specimen in superplastic state The main conditions for a metal to obtain superplasticity are﹕equiaxial﹑

introduction：In the production process，In order to make the medium pressure、The flow rate and other parameters meet the requirements of the process flow，You need to install an adjusting mechanism to adjust the preceding parameters。The main working principle of the regulating mechanism，It depends on changing the flow area between the valve disc and the valve disc and the seat，To achieve the purpose of adjusting the above parameters。Valves belonging to this category are collectively referred to as control valves，It is divided into self-drive control valves such as pressure reducing valves that rely on the power of the medium itself、Pressure regulating valve, etc，Anything thats driven by power ahead（Such as electricity 、Compressed air and hydraulic power）It is called a separate drive control valve，Such as electric regulating valve、Pneumatic control valve and hydraulic control valve, etc。

introduction： Mount the mold on the punch,The process goes like this： 1)Before installation, the cutting edge of the mold should be confirmed，There are no cracks on the edge of the die,The punch has no missing corners。If theres a crack or a missing corner，Please sharpen the edge first。 2)Should be on before closing、A silicon steel sheet is inserted between the lower die，Prevent the knife edge from being hurt during handling。 3)Before the mold is mounted on the press，Use a whetstone to remove burrs from the bottom and top，Clean up the rubbish with strips of cloth。If there are burrs or garbage on the upper and lower surfaces of the mold，Will cause punching burr overshoot。 4)Adjusting slip
