PRESS FOR DEEP PULLING SHEET DETAILS Russian patent published in 2017 - IPC B30B1/34 B21D22/20 

FIELD: machine engineering.

SUBSTANCE: press for deep drawing of hollow sheet parts contains a bed and a traverse connected by columns. On the traverse there is a punch equipped with a hydraulic drive for its movement. On the columns with the ability to move from the hydraulic drive the slider is installed. Provided clamp, which has the ability to swing motion. The clamping movement of the clamping unit is made in the form of at least four hydraulic cylinders arranged on the upper surface of the slide, the drive plate and the central hub. The plate has a spherical surface and is connected by means of ball bearings to the rods of the hydraulic cylinders. The central bushing has a spherical abutment surface responsive to the spherical surface of the drive plate, and is mounted on the lower surface of the slider. The clamp is attached to the drive plate. Hydraulic cylinders are located at an equal distance from the axis of the press with the possibility of providing swing motion of the drive plate.

EFFECT: expanding the technological capabilities of the press and increasing the reliability of its work.
