Presses are designed for the manufacture of parts from sheet and strip products by bending.
In the universal V-shaped stamp supplied with the press, a large number of different parts can be bent. In special dies, delivered for a fee, it is possible to bend complex parts in one transition, bend along the radius, stamp and cut the sheet blanks.
The work of the presses is provided by a hydraulic system containing one or two main cylinders, a pumping unit and a hydraulic control panel. The hydraulic drive for the working stroke provides a quick supply of the slider to the workpiece, a slow stroke during bending and an accelerated retraction to its original position. Adjustment of the position of the slider depending on the thickness of the bent sheet material is carried out by means of a mechanism for adjusting the interstamp space.
Presses with a large table length (ИП 1426В, ИГ 1428) are equipped with a mechanism for compensating for the deflection of the table and slider, which provides high-quality bending with respect to long sheets, significant thickness at nominal force.
Two front stops are installed on the presses, which makes it possible to use them as a receiving table for small batches of workpieces, and a back stop with an indicator of the stop position relative to the bending line, designed for precise positioning of the sheet. On the presses of the models ИП 1426В, ИГ 1428 the back stop is mechanized.
Electrical circuit ensures the operation of presses in single strokes and in adjustment mode.
Press’s control is push-button two-handed and pedal.
Lubrication of the presses is manual.
