Description

one

The invention relates to the processing of solid materials, such as facing stones, and is intended for use in stone processing plants.

Stone cutting machines are known for processing a block of stone, for sawing a block of stone into slabs, and for processing and edging slabs. They consist of a vertical frame, a cross member moving along it, carrying two calipers, which have a cross slide, an intermediate slide rotating on them and a spindle head of the turntable moving on them and a saw drive.

However, such machines are ineffective in operation and are intended only for certain operations.

The aim of the invention is to increase the efficiency of the machine in operation.

For this purpose, the saw blades are mounted in circular intermediate intermediate rails, which in turn are installed in vertical transverse rails, and the axes of the spindles of the supports are horizontally displaced one against the other.

FIG. 1 shows a machine with the installation of saws. For sawing a block of stone into slabs, front view; in fig. 2 is the same, section A-A in FIG. one.

The machine consists of a frame 1 with a crossbar 3 vertically moving along it with the help of drive 2 3. Two cross supports moving across crossbar 3 from drive 4 consist of a cross slide 5 that can move along them vertically from a drive 6 intermediate slide 7 with a rotatable spindle head 8, on the spindle of which circular saws 9 can be mounted on both sides. The rotary table 10, on which the slabs 9 of the billet or the block of stones are mounted and fed, can be moved along the guides 11 from the drive 12.

For cutting the block, the stones of medium hardness on the slab of the saw 9 are mounted horizontally and vertically by turning the spindle heads 8 and are set relative to each other by moving the intermediate slide 7 or transverse 5. The plate is cut in one pass of the saws 9 that do not change positions one relative to another . The vertical movement of the saw blades 9 is carried out by the cross bar 3 along the base 1, and the horizontal movement of the cross bar 5 by the cross bar 3.

For cutting a block of high hardness stones into slabs of the slab 9, they can move horizontally and vertically independently of each other, since the slab is cut to a certain depth in several saws 9. When the slab is cut, the horizontal saw moves the crossbar 5 along the crossbar 3 and the vertical ones The saws are moved by an intermediate slide 7 along the cross slide 5. For sawing up the block of stone, the wide workpieces of the saw blades 9 of both supports are placed horizontally and strictly in the same plane.

The block of stone passes between the saws 9, which cut its upper part to a predetermined plate thickness. Vertically, the saws 9 are moved only by the crossbar 3 along the frame.

Vertical, the plane of the block stone process as follows. Initially, the saws are made by a horizontally set saw, and then the same saw, installed vertically, is cut to the required

the height of the layer of the desired thickness. The processing and edging of the slab is done in the same way as on known machines.
