J58 series electric screw press is a kind of forging equipment with excellent technology applicability. This press is not only used in hot forging but also used in finish forge and finishing；not only used in stainless steel double bottom pan welding technology, but also used in the finish forging of titanium alloy lamina and other laminas. Owning the simple structure, small volume, short transmission chain, convenient operation, safe run, and small quantity of maintenance, the press can set precise strike energy, show the strike power, reduce machine stress and heat-touch time of the mould and prolong its life span.
This press has been applied for state patent product, the patent number is ZL 2005 2 0012542.7
In the case of the screw press with direct drive, the rotor of the drive motor is directly connected to the fly-wheel and the screw.
Special features:
*Precision forging unit with high energy consistence and without kinematical fixed bottom dead centre
*High working capacity
*Press frame combined of several cast parts prestressed by four tie rods.
*Screw made from high-alloy CrNi steel, nut from special bronze
*Optimum thread shape.
*Memory-programmable control system with operator guidance, product data administration and modern for remote diagnosis.
*The optional frequency converter increases the repeatability of the blow energy and the efficienc.
