The structural feature is as follows:I. Brief introduction of structure1,The frame is welding with whole steel platewhich has high rigidity, reasonable structure and beautiful design.2,The press adopts the vertical crankshaft structure. The distance of fulcrum is short and the crank is rigid.Driving gear is installed into the frameand gear is immersed in oil reservoir. Customer could choose Electromagnetic governor(Wannan motor factory), which is stepless speed regulation within a certain range and enlarge the area of craft.3,The press adoptsItaly low inertia combined wetfriction clutch and brake made in Shanghai OMPI,which has little passive inertia, low energy consumption, reliable interlock of clutch and brake and long longevity.4,The slide is a whole cast form construction which adopts hydraulic overload protector made in Showa, Japanwith agile and reliable action. After overload, it can reset automatically to reduce the down time and improve the availability of press. High pressure oil seal which is imported from German is installed in slide high pressure cylinder.5,The shut height adopts electric adjustment, which has digital display. Its display is 0.10mm. The press adopts hexahedral rectangle lengthen gib, which has high guiding precision and steady precision.The press has pneumatic balancer, which reduce the second stroke. It runs smoothly to improve the dynamic precision of press.6,The control part adopts PLC from Mitsubishi, which is efficient to guarantee the reliability of control part.7,The press adopts dual valve from TACO, Japan, which can guarantee the safety and reliability of clutch.8,The press adopts cam controller which be combined with proximity switch. It can send signal exactly within the range of 360°and control the criterion of various actions and the harmony of assist machine to improve the reliability of press.Besides, the press has two-hand operating button and foot pedal switch, which can realize Continuous, Single and Inch mode. II.Guideline of Technical performanceThe model JH21-315 press is manufactured according with accuracy of open press (JB/T 6580-93) and technical requirement of open press (JB/T 6580.1-1998). The security is according with the security and technical terms standard of forging machinery (GB17120-1997) and the security and technical requirement standard of mechanical press (JB3350-93).
