Abstract

FIELD: forging press equipment, namely designs of powered presses.

SUBSTANCE: press includes arranged in housing: slide, flywheel with drive, crank, connecting rods, clutch and brake. Axis of flywheel is parallel relative to motion direction of slide. Crank is jointly coupled with connecting rods and it is mounted in opening of flywheel in parallel and eccentrically relative to flywheel axis with possibility of translation motion. Connecting rods are arranged at both sides from flywheel and they are jointly coupled with slide and with housing. Jointly articulated links of connecting rods are mounted in axle parallel to flywheel axis with eccentricity value relative to it equal to eccentricity value of crank axis. Crank is joined with flywheel through cylinder pair and it is joined with connecting rods through rotation pairs whose axes are normal to crank axis and cross it. Connecting rods are joined with housing and with slide through step bearing assemblies. Such bearing assemblies have common rotation axle parallel to flywheel axis in slide and in housing and they are joined with slides through rotation pairs whose axes are normal relative to axis of flywheel and cross it.

EFFECT: enlarged manufacturing possibilities of press.

Description

The invention relates to forging equipment, in particular to the design of mechanical presses.

Known mechanical press containing located in the frame drive, slider, flywheel. In the groove of the flywheel with the possibility of translational movement parallel to its axis, a crank is mounted pivotally connected by spherical pairs with connecting rods, one of which is pivotally connected by a spherical pair to a slider, and the other to the bed [1].

A disadvantage of the known technical solution is that the slider press has the ability only reciprocating movement.

The invention is aimed at expanding the technological capabilities of the press.

This is achieved by the fact that the press contains a slider located in the bed, a flywheel, the axis of which is parallel to the direction of movement of the slider, in the hole of the flywheel with the possibility of translational movement in parallel and eccentric to its axis, a crank is mounted pivotally connected to the rods located on both sides of the flywheel, the connecting rods respectively with the slider and the bed have hinged connections located on an axis parallel to the axis of the flywheel and eccentric to it by an amount equal to the eccentricity of the axis of the crank, as well as the flywheel, the clutch and the brake, the crank is connected to the flywheel by a cylindrical pair, and to the connecting rods by rotational pairs, the axes of which are perpendicular and intersect with the axis of the crank, the connecting rods are connected to the bed and the slider by means of thrust bearings, while the thrust bearings in the slider and the bed have a common axis of rotation parallel to the axis of the flywheel, and are connected to the connecting rods by rotational pairs whose axes are perpendicular and intersect with the latter.

The drawing shows a frontal section of the press in the extreme upper position of the slider.

The press contains a drive located on the frame 1, a clutch, a brake (not shown). A flywheel 2 connected to the drive is installed in the bed, in a cylindrical hole which is mounted to rotate and move parallel to the axis of the flywheel, the crank 3. The crank is pivotally connected by rotational pairs to the connecting rods 4 and 5. The connecting rod 4 is pivotally connected by a rotary pair to a thrust bearing 6 mounted for rotation in the slider 7. The connecting rod 5 is pivotally connected by a rotary pair with a thrust bearing 8, mounted in the frame with the possibility of rotation.

The thrust bearing in the slider and the thrust bearing in the bed have a common axis of rotation parallel to the direction of movement of the slider and passing through the rotational pairs of connecting rods with thrust bearings, the hinge axes are perpendicular to it, and the axis of rotation of the flywheel is parallel to it and the axis passing through the rotational pairs of connecting rods and crank, and is located equal distance relative to them.

When the rotation of the flywheel 2, the movement of the crank 3 is transmitted to the connecting rods 4 and 5 and then to the slider 7. In this case, the crank 3 is rotated in the hole of the flywheel 2 and moves parallel to its axis of rotation, the thrust bearing 6 rotates relative to the slider, and the thrust bearing 8 rotates relative to the bed. In the extreme lower position of the slider, the axis of the crank coincides with the general axis of rotation of the thrust bearings.
