introduction： one、Construction machinery industry forecast （one）Industry demand analysis Construction machinery estimated in the future3The compound growth rate of annual sales revenue reached35%。Domestic demand，The market is concerned that macro-control will significantly affect the growth rate of fixed asset investment and construction machinery sales，Cicc believes that the impact of macro-control will be lower than market expectations，Industry profit growth will be better than market expectations。External demand，Affected by the subprime credit crisis，The US economy will slow significantly，Chinese exports will slow significantly，Cicc believes that the slowdown in the US economy will have a limited impact on Chinas construction machinery exports，Exports will continue to grow at a high rate。retard

introduction：one、Integrated temperature transmitter The integrated temperature transmitter generally consists of a temperature probe（Thermocouple or thermal resistance sensor）And a two-wire solid state electronic unit。The temperature measuring probe is installed directly in the junction box in the form of a solid module，Thus forming an integrated transmitter。Integrated temperature transmitters are generally divided into two types: thermal resistance and thermocouple。 Thermal resistance temperature transmitter is made by reference unit、R/VConversion unit、Linear circuit、Reverse protection、Current limiting protection、V/IConversion unit, etc。After the signal conversion and amplification，Then the nonlinear relationship between temperature and resistance is carried out by a linear circuit

introduction：The stamping process can be roughly divided into separation process and forming process（Secondary bending、Deep drawing、shaping）Two broad categories。The separation process is to separate the stamping part and the blank along a certain contour line during the stamping process，At the same time, the quality of the separate section of the stamping parts should also meet certain requirements；The forming process is to make the stamping blank plastic deformation under the condition of no damage，And transformed into the desired finished shape，At the same time, it should also meet the requirements of dimensional tolerance。 According to the temperature at the time of stamping, there are two ways of cold stamping and hot stamping。It depends on the strength of the material、plasticity、thickness、Deformation degree and equipment capacity, etc，Lumber should also be considered
