The main assemblies of the horizontal horizontal press are the base 1, the drive shaft 2, the crank shaft 3, the working slide 4 with the pressure supports 5, the support slide 6 with the pressure supports 7 and the support rollers 8.

The drive of the working slide 4 contains an electric motor 9, a pulley Yu, a V-belt 11, a flywheel 12, a gear 13 connected to the drive shaft 2, and a gear wheel 14 interacting with the crank shaft 3 and the connecting rod 15. The crank 15 is connected through an axis 16 and piston 17 with a gear half coupling 18 and an axis 19.

The pressure supports 5 and 7 of the working 4 and supporting 6 sliders, respectively, have driving rack mechanisms with power pneumatic cylinders 20. The piston 21 of each pneumatic cylinder 20 has a rail 22 coupled to gear 23, which is engaged with gear 24 and rail 25, and gear 24 is in engagement with the rail 26.

A cavity 27 is inserted in the support slider, in which a connecting nut is installed in the shape of a finger 28. An aperture 29 is made perpendicular to the finger axis, and the drive screw 30 of the support slider drive mechanism 6 is passed through it. Hole 29 can either be threaded or contain threaded crackers. The connecting finger 28 is made lightweight in the form of two hollow mutually perpendicular (vertical and horizontal) cylindrical elements, through one of which (horizontal) screw 30 is passed, and in the other (vertical) in the grooves 31 and 32, the axis 3 of the roller bearing 34 is fixed, made on bearings with seals across the entire width of the internal cavity of the finger 28, which

The torus rests on the guide ZZ of the frame 1. In screw 30, an internal cavity 36 is made, serving as a reservoir for the oil. The screw contains a cover 37.1, a plug 38, a closing hole for filling the oil, an oil indicator 39 for determining the oil level and radial lubrication channels 40. In the pin 28 for lubricating the thread of the screw 30 there is a sealed chamber limited to rubber in the seals 41 and 42 placed on the screw 30 and rigidly connected with the finger 28.

The drive of the supporting slide 6 consists of an electric motor 43, a gearbox 44, an open gear train 45 and a lead screw 30.

Horizontal right press works as follows.

From the electric motor 9, the pulley 10, the V-belt transmission 11, the flywheel 12, the drive shaft 2, the gear 13, the gear wheel 14 and the crank shaft 3 5 are transmitted to the connecting rod 15. When the connecting rod 15 is pressed, the shaft 16 and the piston 17 are turned on the gear half coupling 18 around the axis 19 in such a way that in one position its cams (not shown) are located with the piston cams 17, and another between the cams of the piston 17. When the cams of the coupling half 18 are located above the cams of the piston 17, the press turns on and the slider 4 is set in motion .

The movement of the pressure supports 5 and 7 along the axis of the rolled products is carried out by the movement of the piston 21 and associated with it by means of gears 23 and 24 of the rails 25 and 26.

The movement of the support slider 6 is carried out from the electric motor 43. Its rotation is transmitted through the reducer 45, the open gear 45 to the lead screw 30, which passes through the finger 28. The lead screw 30 rotates and interacts with the thread of the finger 28 and moves the latter together with the supporting slide 6 along the bed frame guide 1 In doing so, the support 34 rolls along the guide 35.

During the operation of the press, the slide 6 has the ability to vertically move along the axis of the finger 28 and perform swing movements around it. For example, when increasing the clearance in the direction of

slider 6 has the ability to rotate in a horizontal plane and lower relative to a pair of spindle screw 30 - a connecting pin 28 in a vertical plane without re-installing the drive of the reference slider 6 without creating transverse forces at the joints.

From reservoir 36, made in screw 30, the lubricant through radial channels 40 enters a sealed chamber in finger 28, bounded by threaded seals 41 and 42, placed on screw 30 and connected

with a finger 28. The oil is poured into the cavity of the screw 30 (tank 36) through a hole closed by a plug 38, the oil level is monitored by the oil indicator 39.

The relief of the connecting pin 28 and the lead screw 30, as well as the implementation of the screw in the form of a reservoir for lubricating and sealing the lubricated threaded sections of the screw and the finger, improve the working conditions of the horizontal press.
