ACCESSORIES FOR FORGING

ACCESSORIES FOR FORGING
GEVA  with itas 40 years experience has developed solutions usable and integrated for the hot forging of metal.

Infrared detectors

Detectors developed by GEVA permits checking of the pieces for loading and unloading in a hot forging press. 
Each detector has a metal casing that allows waterproofing from oil splashes.

Mod. SI-101 - Loading detector for brass.
The loading sensor GEVA SI-101 detects an infrared rays emission from hot workpieces having a temperature higher than 500°C.
When the workpiece enters the optical cone of the detector, the latter sends an electric impulse to the PLC, which records the workpiece presence and allows the automation to load the press dies. A potentiometer allows to set the sensor sensitivity (quantity of infrared radiation absorbed) depending on the workpiece temperature. When the knob is turned in a clockwise direction it increases the sensitivity of the sensor for detecting  low temperatures.

Mod. SI-200 - Loading detector for steel.
The loading sensor GEVA SI-200 detects an infrared rays emission from hot workpieces having a temperature higher than 700°C.
When the workpiece enters the optical cone of the detector, the latter sends an electric impulse to the PLC, which records the workpiece presence and allows the automation to load the press dies.

Mod. SI-500 - Unloading detector for brass/steel.
The unloading sensor GEVA SI-500 detects an infrared rays emission from hot workpieces having a temperature higher than 450°C.
Unlike the load sensor, the unload sensor records an instantaneous emission of infrared rays within its optical cone. This characteristic makes it particularly suitable for detecting the presence of the part on the unloading arm during rapid rotation.
The electric impulse sent to the PLC lasts about one second.
The structure of the sensor and the arrangement of the electric components inside it are similar to those of the load detector.
It differs in the presence on the casing of a small trimmer in place of the potentiometer, which allows regulation of the sensor sensitivity depending on the part temperature. To increase its sensitivity, turn the trimmer in a clockwise direction.
