Brake is automatically applied when the clutch is released. In other word, as the compression value for the testing piece jjs criterion, set the figures of equivalent amount on the load gauge. Air Filter, Regulator and Lubrication unit. Brake motor drives the worn shaft and wheel made of P. In case of the operation, hard-on-hard, in which striking die against die with the same condition as the above item?

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.

Standard Equipments with each machine. The allowable performance for the former is 1. Ejector bar jus slide. It would be accurately machined and ground finished and so designed to ensure optimum factor of safety.

When you set up two strain gauges at each side of the frame, the load on one side frame equals to a half of the load becomes setting value and shown as certain kN in RH and LH independently, plus total kN in the display. Jks don’t use the torque limiter approach attached to the flywheel discharging overload energy.


The required speed is previously set on touch panel or by setting dial.

640 Overload Protection The machine is equipped with a standard v operated hydraulic overload safety device. Squirrel Cage Electric Motor. 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 nominal capacity of kN press?

As explained earlier, the press can compress a test piece with nominal capacity, however, it is absolutely impossible to do with the allowable capacity. Acceleration and speed reduction are combined automatically to apply power with the Minimum time for one cycle. Basically, eccentric load out of the screw diameter should be avoided. There are always risks that the load surpasses the allowable load.

Standard bolster with T-slots. Machine life is drastically shortened if the press is used under three more times of nominal capacity maximum capacity repeatedly usually, the screw and the frame get damage. We are taking the method that the machine gives warning signal jid operator through LED lamp when the machine is in overload emergency stop status from electric signal of the load gauge note We don’t use the torque limiter approach attached to the flywheel discharging overload energy.

Home Products Profile Brochure Contact. In the screw press, generally, the forming energy is adjusted with slide speed control just before stamping.

Kaushico Machine Tools Pvt. Ltd.

Rotary 3 position Cam Limit Switch. 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. This prevents any damage to the tool and to the press.


It’s hardly recognizable to the operator if the torque limiter functions under the overload condition. The capacity of screw press 602 be used with the nominal capacity.


Dual Sensing Solenoid valve. In this status, compress the testing work piece and detect the frame deformation through strain gauge to show kN value on a load gauge. Two independent load display for each side simply shows one sided load and the total load is defined as screw press load.

The screw press of kN; Set the load gauge that shows figures of when the testing work piece jiis compressed with the equivalent of kN. The load that can be allowable becomes reducing when it becomes far from the center. Because the press is designed to deform product, not for assuming of crashing tools themselves repeatedly. If the preset value is small, the slide is clutched off ji after acceleration and it descends evenly with inertia.

It becomes quite expensive machine though we could manufacture it. During work process like vertical jiz of heated bar material, the energy is consumed for plastic deformation of the material mostly and the frame bears very small amount of load shown low value on the load gauge.
