Abstract

The invention relates to the automation of technological processes in mechanical engineering, in particular, to the orientation of rectangular or square section blanks when supplying them to an induction heater or when loading blanks in the lines of punching and machining. The aim of the invention is the expansion of technological capabilities by providing orientation of rectangular or square section blanks. For this purpose, the orientation disk 3 in the device is made in the form of a truncated cone. At the point of conjugation of the disk with the outer orienting ring 4, the workpieces, oriented along the axis of movement due to the loading moment, roll onto the ring 4. Preparations, oriented in another way, continue to remain on the disk, since the projection of their center of gravity lies within the upper the base of the disk 3, and come in when the disk is turned on to re-orientation until they take the appropriate position. 3 il.

The invention relates to the automation of technological processes in mechanical engineering, in particular, to the orientation of rectangular or square section blanks when they are fed into an induction heater or when loading blanks in stamping and machining lines, and is an improvement of the device according to the author. No. 1199580.

The purpose of the invention is to expand the technological capabilities of the device by providing orientation of rectangular or square section blanks.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows the node I in FIG. one.

The device consists of a fixed housing with a rim 2, in the inner part of which an inner orienting disk 3 and an outer orienting ring 4 are installed, receiving rotation from a common drive 5. The planes of the disk 3 and the ring 4 form an angle a between themselves (as well as their axes of rotation) and match at point A.

The angle a of the inner disk 3 to the horizontal is selected from the condition of the blanks sliding (chopped on a shearing press and having sharp burrs) along the upper base of the disk 3 and is not less than 13 °.

Behind the zone of greatest elevation of the outer orienting ring 4 cal is an internal disk 3. on the tangent to the outer ring 4 there is an output tray 6.

The outer ring 4 is the flange portion of the spherical bowl 7, on which gears 8-10 are attached. In case 1, along the axis of the bowl, it is installed with a possibility) (with a turn bone, the supporting shaft II. The immobility of shaft 11 relative to case 1 in any position is provided by a lock 12.

The support shaft 11 can be unlocked and rotated relative to the housing and, therefore, the output tray. In this case, the interface of the inner disk 3 and the outer ring 4 either approaches the output tray 6 or is removed, and this allows the number of oriented (lined along the board) blanks to change, and therefore, the amount of backwater is necessary, which is necessary for reliable operation of the orientation device.

The actuator 5 has an output gear 3, which engages with the gear 8. On the axis of the internal disk 3 there is a shaft-gear 14, which engages with the internal bevel gear 9.

The internal disk 3 is made in the form of a truncated cone. The forming cone in the place of its conjugation with the orienting ring forms an angle with the horizontal 103-135, necessary and sufficient for tilting square billets or mr0

coal section on the orienting disk (Fig. 3).

The excess of the highest point of the orienting disk over the surface of the orienting ring is at least half of the side of the cross section of the oriented workpiece (larger in range) and is 10-100 mm (Fig. 3).

The device works as follows.

Billets are fed in small portions (150-200 kg) (for example, by vibratory flow from the hopper) to the inner disk 3 and turn on the drive 5, which through gears 13 and 8 transfers the rotation to the spherical bowl 7, and through gears 9 and 14 to internal disk 3. When the disk 3 rotates, due to its inclination to the horizontal of the workpiece, the spherical bowl 7 slides down along its upper base along its upper base.

A prism is formed between the spherical surface of Chazz 7 and the conical surface of the disk 3, with which the workpiece that has entered it is pre-oriented along the line of separation of the spherical surface of the thicket 7 and the conical surface of the disk 3. When the bowl 7 and the disk 3 rotate, the workpiece is transferred to the upper point of its trajectory ( the interface of the inner disk 3 with the outer orienting ring 4). At the same time, it forms against the inner lining of the inner surface of the thicket 7. As the workpiece advances, the angle of the prism increases (because the axis of rotation of the disk 3 is at an angle to the axis of the holding of the bowl 7).

In the interface of the disk 3 with the ring 4, the spherical part of the prism passes into the horizontal plane of the ring 4. Thus, in this area, the prism opens with one of its face and continues to direct the workpiece with another face (the conical surface of the disk 3). tilts from the surface dividing line to the horizontal orienting ring 4. Next, the blank guided by the board is transferred by ring 4 to the output tray 6, where the roller feeder is continuously or cyclically pushed through duktor.

Improperly oriented workpieces (for example, oriented transversely to the axis of movement) remain on the inner disk 3 for re-orientation due to the fact that the center of gravity of the workpiece is not shifted beyond the upper stiffening of the disk 3. With the V-shaped junction between the generatrix of the inner disk 3 and the spherical surface The blanks 7 of the workpiece are oriented mainly correctly along the line of separation of the planes.

The center of gravity of a properly oriented workpiece is constantly mixed beyond the upper base of the disk 3.
