Screw Press with direct electric Drive has the shortest transmission chain and very high efficiency. At present, Switched Reluctance Motor is developing popularly in CNC electric Screw Press

 

2. Characteristics of J*8K series electric Screw Press

 

a) Screw Press with direct electric Drive has the Characteristics of big starting torque, small starting curren, small electrical network impact. Because of stop-and-go driving, starting and stopping velocity can be set according to the technological requirement.

 

b) Because the angular speed of electrical motor can be regulated in a of stepless speed way, both the slide stroke number of times and the blow energy can be numerically controlled ,set and Controlled in program according to the technological requirement. So the deformation uniformity of  workpiece can be Guaranteed, mechanical stress and hot contact time of die can be reduced , die life can be prolong. Also adjustment and test of die is convenient, productive capacity has been increased.

 

c) It is guaranteed that the slide stops in designated position when this machine is normally stopped because the position transducer can feed back the position signal so that the motor decelerates before this machine is stopped, and the brake is applied when the slide is in preset position in oder that the slide stops in designated position. So we can adjust the stroke height conveniently. Also the backward position is accurate.

 

d) The security is high because the slide can stops in optional position under the brake action of the motor and the brake

 

e) In most cases, the press works in the non -rated condition. Switched Reluctance  Motor have lower energy consumption than other motors. When this press is In a low running velocity, the energy conservation is more obvious. Without idle operation of frication wheels such as  Frication Screw Press, Screw Press with direct electric Drive reduces the system energy consumption above *0%. So it saves energy.

 

f) Because of Switched Reluctance Motor have simple structure, high mechanical strength, they are suitable for the strong impact and the strong vibration environment.Thus operational reliability of Screw Press with direct electric Drive is high.

 

Screw Press with direct electric Drive has the advantages such as high forging  precision, high production efficiency, easy to realize the automation, low  worker's operative technique level, slight noise , etc. It is a kind of advanced product  which  adapts to modern forging industry.
