Abstract

Use: cleaning of bur during thermal cutting. In the lower disk of the copier block there are grooves in which there are copier rollers with a diameter greater than the depth of the slots. The impacting head rotates relative to the body with cutting elements that are installed with the possibility of fixed movement relative to it by 1 Cpfly 4 sludge.

Description

The invention relates to mechanical engineering, in particular to the debridement of the edges of flat blanks (products), for example, obtained from a sheet by thermal cutting.

The purpose of the invention is to increase reliability by increasing the durability of the copy elements while reducing the size of the device.

The goal is achieved by the fact that the lower disk of the copier block is made with grooves, the copier elements are made in the form of rollers with a diameter exceeding the depth of the grooves and are installed in these grooves and the cutting elements are installed with a possibility of a fixed movement in height relative to the impacting head.

Owing to the cylindrical rollers freely suspended in the slots of the lower disk on the horizontal axes of the copier, it becomes possible to roll over it (rather than abutting) when meeting with burrs on the edge of the sheet, also due to the height adjustment of the cutting elements, relative to the impact axis head, providing a gap between the surface of the workpiece, sufficient to remove burr, but excluding touching the entire plane of the workpiece, in general, the reliability of the device.

Fig, 1 shows the proposed device, the cut; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2 in FIG. 4 shows a section B-B in FIG. 3

The deburring device contains a copier block 1 and a striking head 2. The copier block 1 consists of a shell 3, an upper support disc 4 with stops 5. a lower disc 6, in the slots of which copiers are placed in the form of rollers 7, freely suspended on horizontal axes 8, eliminating the falling out of the rollers 7 of the copier unit 1 whose diameter exceeds the depth of the groove

The impact head 2 consists of a body 9. in which circumferentially, using screws 10, sleeves 11 and nuts 12, fasten the cutting elements Oyuka 13 in height) 13. made in the form of disk plates with cutting edges.

The copier block 1 is attached to the flange 14 of the housing 15 of the processing head 16. And the shock head 2 is mounted on the spindle 17 of the processing head 16.

The device works as follows.

In the course of work, a workpiece is fed under the processing head 16 with a rotating impact head 2, from which it is necessary to remove the burr. When meeting with the workpiece, the copier rollers 7 of the copier block 1 overlap grata and then, rolling over the workpiece surface, through the stops 5 of the upper bearing disc 4, as it were, determine the constancy of the working gap between the workpiece surface and the cutting elements (strikers) 13 of the shock a head 9 sufficient to cleave burrs from the surface of the workpiece without touching it.

The lowering of the cutting elements (dies) 13 below the surface of the workpiece is excluded, since the shock head 2 is surrounded by the copier rollers 7 of the copier block 1.

The proposed deburring device reliably and qualitatively removes the bur.
