Acceleration and speed reduction are combined automatically to apply power with the Minimum time for one cycle. Jus centralized Motorised Lubrication Pump.

Standard Equipments with each machine.

During work process like vertical compression of heated bar material, the energy is consumed for plastic deformation of the material mostly and the jos bears very small amount of load shown low value on the load gauge. The capacity of screw press should be used with the nominal capacity. The slide speed adjustment takes the method that controls to have same speed every cycle based on encoder signal detected the slide descending speed.

It’s hardly recognizable to the operator if the torque limiter functions under the overload condition. At the time of overload, by exceeding the rating capacity tonnage, the sensitive Hydraulic Overload Protection device senses the overload with a millisecond and immediately stops the machine.

Basically, eccentric load out of the screw diameter should be avoided. In case of the operation, hard-on-hard, in which striking die against die with the same condition as the above item?


Using the allowable capacity is disputable from the point of fair business transaction. You can adjust the slide speed freely adjustable forming energy freelyhowever, you can’t control how many kN to strike. 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. Die Cushion capacity at 7.

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. Home Products Profile Brochure Contact. Also, these are proportional to slide descending speed, too.

Air Filter, Jia and Lubrication unit. Naturally, if you form product under the same condition, the slide speed adjustment is proportional to the load gauge display.


The load gauge simply 66402 the result of how many kN loaded to the frame. We don’t use the torque limiter approach attached to the flywheel discharging overload energy.

We are taking the method that the machine gives warning signal to operator through LED lamp when the n is in overload emergency stop status from electric signal of the load gauge. The frames are stress relieved before machining. Especially, in those large edge burrs and cold working, it could become out of the allowable load even if the forming energy value is still a half of it.

There are always risks that the load surpasses the jix load. Web Design City Dubai. The required speed is previously set on touch panel or by setting dial. The screw press of kN; Set the load gauge that shows figures of when the testing work piece is compressed with the equivalent of kN. Hydraulic Overload safety device. Therefore, the press needs to have emergency stop mechanism if the overload happened. Hydraulic Overload Protection The machine is equipped with a standard pneumatically operated hydraulic overload safety device.

Crank Shaft The Crank shaft would be of forged and normalized medium carbon steel to ensure toughness and shock resistance. On the contrary, cold 640 stamping or stamping of steel plate with many edge burrs indicates large figures on the load gauge even if energy adjustment is relatively small. In the screw press, generally, the forming energy is adjusted with slide speed control just before stamping.

The load that can be allowable becomes reducing when it becomes far from the center. Evaluation of the screw press capacity is made with testing a work piece in cold compression. Brake motor drives the worn shaft and wheel made of P. Since the screw press has no mechanical lower-dead-point, the machine never stops caused from mis stick like the crank press machine.
