The flywheel revolution is sequentially controlled in a servomotor direct driven system without clutch transmission.

The allowable performance for the former is 1. The required speed is previously set on touch panel or by setting dial.

In the screw press, generally, the forming energy is adjusted with slide speed control just before stamping. Standard bolster with T-slots. We are taking the method that the machine gives warning signal to operator through LED lamp when the machine is in overload emergency his status from electric signal of the load gauge.

The clutch is engaged through air pressure.

Pneumatic balancer for slide 2 nos. During work process like vertical compression of heated bar material, the energy is consumed for plastic deformation of the material mostly and the frame bears very small amount of 64002 shown low value on the load gauge.

It would be accurately machined and ground finished and so designed to ensure optimum factor of 640. Its control is where the point to clutch off, not kis control like inverter motor. On the contrary, cold working stamping or stamping of steel plate with many edge burrs indicates large figures on the load gauge even if energy adjustment is relatively small.


Set up the press slide speed and the slide stroke as maximum adjust to maximum power. The load should be placed on the center fundamentally. The main frame plates are in one piece re-enforced by ribbing wherever necessary to provide rigidity to the frame and assuring least defection on full load.

That means that there exists a risk that the machine is used under 64022 situation without knowing. Ejector bar in slide. Dual Sensing Solenoid valve.

Kaushico Machine Tools Pvt. Ltd.

Hydraulic Overload Protection The machine is equipped with a standard pneumatically operated hydraulic overload safety device. Hydraulic Overload safety device.

Naturally, if you form product under the same condition, the slide speed adjustment is proportional to the load gauge display. As explained earlier, the press can compress a test piece with nominal capacity, however, it is absolutely impossible to do with the allowable capacity.

Especially, in those 4602 edge burrs and cold working, it could v out of the allowable load even if the forming energy value is still a half of it. The frames are stress relieved before machining.


Here a h occurs how much the allowable applied load of a press being set witch coming from rigidity design of machine. Our company does not employ this method because in case of hardened spring adjustment of the torque limiter by mistake, machine may always running with overload and finally machine may brake.


Home Products Profile Brochure Contact. It becomes quite expensive machine though we could manufacture it.

Die Cushion capacity at 7. Attention is required that there is no relationship or relativity between the forming energy and the load display. The slide speed adjustment takes the method that controls to have same speed every cycle based on jiis signal detected the slide descending speed.

Surely, it is possible, however, can you imagine and would like to have the screw press that has the frame of kN press with flywheel of kN press and is used as n capacity of kN press? Brake motor drives the worn shaft and wheel made 602 P. Because the press is designed to deform product, not for assuming of crashing tools themselves repeatedly. You may recognize from the above discussion that the load gauge display quite differs when smash up a test piece or strike die against die even if the forming energy is the same.

The load that can be allowable becomes reducing when it becomes far from the center.
