The invention relates to metallurgy and can be used on abrasive grinding machines for machining square billets.

The purpose of the invention is to increase productivity by allowing the cleaning of the edges and edges of square blanks from a single installation, reducing the size of the device, JQ as well as turning and fixing several blanks simultaneously.

FIG. 1 shows the installation of tilters on the table of the abrasive-grinding machine in FIG. 2, section 2 —AA | in fig. 1 in FIG. 3 shows a section BB in FIG. one; figure 4 - section bb In fig. one . Tilter square blanks for kolovki long blanks (6-12

1, mounted on the table 2 abrasive-grinding machine 3 with hydraulic actuator 4. Each tilter 1 has one or more tilting and clamping mechanisms 5, Tilter 1 consists of a stand 6, made in the form of a plate beam with two channels, which installed mechanisms kantovka and clamping the workpiece. The stand is equipped with rectangular grooves 7, inclined to the horizon at an angle of 10-20. Under the elevated parts of the inclined grooves 7, axles 8 are equipped with two arms short levers 9, the lower ends of which are connected to the hydraulic cylinders 10, and the upper arms are made in the form of wedges. Levers 9 installed so that when they are turned, the wedge-shaped part can enter into the section of inclined grooves 7 or be installed under them, i.e. under the slopes of the inclined grooves, under the understated portions of the inclined grooves 7 (fig. 4), rails-clamps 13 are installed in the rails 1 and 1 racks on the rollers 12, the lower part of these clamps is connected to the hydraulic cylinders 14, a grinder with the possibility of overlapping a part of the cross section of the slots 7 to a height equal to (0.1-0.3) the size of the face of the workpiece, or leaving the cross section of the slots 7.

Tilter works as follows.

The workpiece 15 to be stripped around the edges and edges fit into the grooves 7, while the clamp 13 is located outside the cross section of the grooves 7, the hydraulic cylinders 14 are turned on, the workpiece 15 moves to an elevated wall

groove 7 and clamped. After processing one face and the edge of the workpiece 15, the clamps 13 are retracted from the workpiece by a small stroke.

The hydraulic cylinders 10 are turned on. Turning, the levers 9 with their pointed ends rotate the workpiece 15, the latter then abutting with its face into the projecting part of the clamp 13, and with further rotation of the levers 9 it is turned over and laid on their upper plane. Hydraulic cylinders included

14, the clips 13 extend beyond the cross-section of the grooves 7, the workpiece 15, resting against the understated wall (edge) of the groove 7 and turning at a small angle, fits its lower edge on the bottom of the grooves 7, the hydraulic cylinders

Move and clamp the workpiece. In the subsequent cycles, the turning and clamping of the workpiece are repeated.

Making slots inclined at 10-20 ° to the horizon provides ease of installation and clamping the workpiece for machining one face and edge of a square billet with an abrasive grinding machine. The inclination of the grooves also contributes to improving the condition of turning the workpiece with the lever 9 on the upper plane of the clamps,

The protruding part of the clips of the supremely low inclined grooves C is (0.1-0.3) a, where a is the size of the billet face. This size allows the blank to be easily skanted onto the upper plane of the clamps and, when they exit from under the blank, eliminate its reverse rotation, even when the position of the levers 9 is retracted from the blank, and the height of the part of the clamps that protrudes above the bottom of the grooves is recommended. .

The wedge-shaped shape of the upper parts of the levers 9 allows them to be removed from the cross section of grooves inclined to the horizon in cramped / conditions, at small distances from the axes of the levers to the bottom of the grooves and to the axes of the hydraulic cylinders, i.e. contributes to the compactness of the device.

Making canting racks in the form of plate beams with two channels for accommodating tilting and clamping mechanisms, making grooves inclined to the horizon in them, installing short double-arm levers and sliders of clamps 7 and 7 to be clamped under them. After processing one face and the edge of the workpiece 15, the clamps 13 are retracted from the workpiece by a small stroke.

The hydraulic cylinders 10 are turned on. Turning, the levers 9 with their pointed ends rotate the workpiece 15, the latter at the same time abutting its face on the projecting part of the clamp 13, and with further rotation of the levers 9 it is turned over and laid on their upper plane. Hydraulic cylinders included

14, the clips 13 extend beyond the cross section of the grooves 7, the workpiece 15, resting against the understated wall (edge) of the groove 7 and turning at a small angle, fits with its lower edge on the bottom of the grooves 7, the hydraulic cylinders are activated

Move and clamp the workpiece. In the subsequent cycles, the turning and clamping of the workpiece are repeated.

Making slots oblique at an angle of 10-20 ° to the horizon provides ease of installation and clamping the workpiece for machining one face and the edge of a square billet with an abrasive disc grinding machine. The inclination of the grooves also contributes to improving the conditions for turning the workpiece with the lever 9 to the upper plane of the clamps

The protruding part of the clips of the supremely low inclined grooves C is (0.1-0.3) a, where a is the size of the face of the blank. This size makes it easy to skim the workpiece onto the upper plane of the clamps and, when they exit from under the workpiece, eliminate its reverse rotation, even with the position of the levers 9 retracted from the workpiece, and the height of the part of the clamps that protrudes above the bottom of the grooves is recommended to clamp the workpiece.

The wedge-shaped form of the upper parts of the levers 9 allows them to be removed from the cross section of grooves inclined to the horizon in cramped / conditions, at small distances from the axes of the arms to the bottom of the grooves and to the axes of the hydraulic cylinders, i.e. contributes to the compactness of the device.

Making canting posts in the form of lamellar beams with two channels for accommodating tilting and clamping mechanisms in them, making grooves inclined to the horizon in them, installing short double-arm levers and slide blocks with them

The protruding portions above the groove and the combination of the function of the movable stop and clamp provide the ability to clean the edges and edges of square blanks on abrasive-grinding machines, increase the compactness of the mechanisms and provide the ability to process one, two or more blanks, which increases productivity. When processing one blank, you can skantovat and clamp another blank. The condition of the compactness of the device also contributes to the one-sided, to the center of the axis of the machine table, the placement of hydraulic cylinders.
