The flywheel revolution is sequentially controlled in a servomotor direct driven system without clutch transmission.
SPECIFICATIONS MODEL : ‘ESR’
During work process like vertical compression of heated bar material, the energy is consumed for plastic deformation of the material mostly and the jsi bears very small amount of load shown low value on the load gauge. Therefore, the press needs to have emergency stop mechanism if the overload happened.
We don’t use the torque limiter approach attached to the flywheel discharging overload energy. Emergency stopwatch would be provided in the control panel.
Home Products Profile Brochure Contact. Squirrel Cage Electric Motor. Also, these are proportional to 642 descending speed, too.
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. Naturally, if you form product under the same condition, the slide speed adjustment is proportional to the load gauge display.
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. The frames are stress relieved before machining. You may recognize from the above discussion that the load gauge display quite differs when smash iis a test piece jia strike die against die even if the forming energy is the same. Using the allowable capacity is disputable from the point of fair business transaction.
It’s hardly recognizable to the operator if the torque limiter functions under the overload condition. Evaluation of the screw press capacity is made with testing a work piece in cold compression.
Standard bolster with T-slots. The slide speed adjustment takes the method that controls to have same speed every cycle based on encoder signal detected the slide descending speed. Brake is automatically applied when the clutch is released.
Dual Sensing Solenoid valve. Acceleration and speed reduction are combined automatically to apply power with the Minimum time for one cycle.
Hydraulic Overload safety device. The load that can be allowable becomes reducing when it becomes far from the center. The capacity of screw press should be used with the nominal capacity. It becomes quite expensive machine though we could manufacture it.
The machine is made operational by pushing the reset 64002. We are taking the method that the machine gives warning signal to operator through LED lamp when the machine is in overload emergency stop status from electric signal of the load gauge.
Web Design City Dubai. If the preset value is small, the slide is clutched off right after acceleration and it descends evenly with inertia. The required speed is previously set on touch panel or by setting dial. That means that there exists a risk that the machine is 642 under overload situation without knowing.
Kaushico Machine Tools Pvt. Ltd.
Since the screw press has 6420 mechanical lower-dead-point, the machine never stops caused from overload stick like the crank press machine. The load gauge simply displays the result of how many kN loaded to the frame.
In the screw press, generally, the forming energy is adjusted with slide speed control just before stamping. Ejector bar in slide.
Rotary 3 position Cam Limit Switch. Die Cushion capacity at 7. The load should be placed on the center fundamentally. Brake motor drives the worn shaft and wheel made of P.
JIS B – Mechanical power presses — Testing of the accuracy (FOREIGN STANDARD)
G are always risks that the load surpasses the allowable load. Frame is stretched by three times This three time figure shows the maximum applied load of the press. Pneumatic balancer for slide 2 nos.
Here a problem occurs how much the allowable applied load of a press being set witch coming from rigidity design of machine. Attention is required that there is no relationship or relativity between the forming energy and the load display.
