Abstract

FIELD: foundry.

SUBSTANCE: apparatus includes base, housing with drive unit, lower and upper traverse bars rigidly joined one with other through columns, part feeding mechanism with drive unit. Columns are mounted with possibility of vertical motion inside struts. Each strut supports lever. Levers may engage with rollers mounted on upper traverse bar. Tool for working opening in bottom portion of part is mounted on lower traverse bar. Parts are placed onto fixing members and they are moved to working zone by means of tool. Bearing plate moved by means of drive unit and fixed by means of levers is provided for fastening part. By moving upwards lower traverse bar with tool, bottom openings of part are pressed through.

EFFECT: enhanced operational reliability of apparatus.

Description

The invention relates to foundry and can be used in the processing of cast parts.

A device for processing foundry bays for AS No. 680810 of 05/10/77, containing a base, a housing with a drive and a tool for processing holes in the bottom of the part, a feed mechanism for parts with a drive and with clamps, a vertical displacement drive.

A disadvantage of the known device is that the drive for vertical movement of the tool for punching holes in the bottom of the part is located at the bottom of the device, under the tool, due to which a large amount of waste gets into the drive during processing of the part, this leads to failure of the drive, but A known device can be taken as a prototype.

An object of the invention is to increase the durability and reliability of the device.

The technical result is achieved by the fact that the device for processing casting bays is provided with a base, a housing with a drive, a mechanism for feeding the part with a drive and with clamps, a tool for processing holes in the bottom of the part, traverses rigidly connected to each other by means of columns, at least one drive vertical movement with a thrust plate mounted on the upper crosshead, uprights with levers placed on them, while the tool for processing holes in the bottom of the part is placed on the bottom her traverse. Columns are arranged with the possibility of vertical movement inside the racks, and the levers have the ability to interact with the rollers.

Placing the tool drive for processing holes in the bottom of the part in the upper part of the device increases the durability and reliability of the entire device.

Figure 1 shows a General view of the device, figure 2 - section aa in figure 1.

A device for processing casting bays contains a base 1, a housing 2 with a drive 3 and with a tool 4, a mechanism 5 for supplying the part 6 with clamps 7, a lower beam 8, an upper beam 9. A tool 10 is placed on the lower beam 8 for forcing holes in the bottom of the component 6. To the rods 11 of the actuator 12 (actuators 12 in the device can be from 1 to n pieces) vertical movement is attached to the upper beam 9 with two rollers 13. The lower beam 8 and the upper beam 9 are rigidly fastened to each other by means of two columns 14. Based on the cases privo An axial plate 15 is installed for the vertical movement disks 12. Both columns 14 have the ability to move inside two racks 16, each of which is located on the lever 17.

The device operates as follows.

Part 8 is installed on the latches 7, turn on the mechanism 5 for supplying the part 6 and move it to the processing zone with the tool 10. The bases of the bodies of the vertical movement drives 12, with the thrust plate 15 installed on them, go down to the stop on the part 6. At this time, when moving the rods 11 of the actuators 12 of vertical movement, both levers 17 are released from contact with the rollers 13 attached to the upper traverse 9. Each lever 17 under the action of a spring (not shown) is rotated on its axis (not indicated), the position of the unit is fixed polar plate 15, whereby the position is fixed and held by the part 6.

Together with the upper traverse 9, the upward movement is performed by both columns 14, the lower traverse 8 with the tool 10, at a distance equal to the stroke length of the rods 11. During the upward movement, the tool 10 pushes the bottom holes of the part 6.

After completion of the movement of the rods 11 they return in the opposite direction, i.e. down, reporting a downward movement of the upper traverse 9, columns 14, lower traverse 8 with the tool 10. All returns to its original position, while the levers 17 come in contact with the rollers 13, turn on their axes (not indicated), are removed from contact with the persistent plate 15, which during the final movement of the rods 11 rises up, the casting is released.

The pedal mechanism of part 6 moves it into the body 2, into the processing zone by tool 4. By means of the drive 3, tool 4 processes the side holes of part 8, then, by mechanism 5, it is removed from the processing zone, the processing cycle is completed and can be repeated with another part.
