Abstract

A core sawing machine containing a guide in the form of a hollow pipe with a slot (5) for a cutting tool (6) and a pusher (9) installed in the end of the guide. The diameter of the guide is made slightly larger than the diameter of the core (4). The machine is additionally equipped with a device (12) for sawing large core samples. The implementation of the guide in the form of a pipe with d is slightly larger than the core being sawn, provides reliable fastening of the latter, and does not require an additional mechanism for fixing the core during sawing. 1 n.p. f-ly, and 2 z.p. f-ly, 2 ill.

Description

The utility model relates to mining equipment and, in particular, to cutting rock samples by the wet method.

A known machine for cutting stone containing a bed, the mechanism for securing the workpiece, made in the form of a carriage, a device for attaching a tool and a tank with coolant. (RF Patent No. 2024396, M. Pk B28D 1/04, Publish 12/15/1994)

The disadvantage of the design is the complexity and narrow design range of workpieces.

The closest is a machine for longitudinal sawing core "RASPIL-1M." Designed for core cutting up to 110 mm in diameter with an adjustable feed rate of the cutting tool. It is also possible to machine the rock samples and other types of sawing at a cutting angle of 90 °.

The machine contains a bed, a movable carriage with a handle, guides of a movable carriage, a cutting tool, a mechanism for adjusting the depth of cut, a protective casing, spray protection aprons, a work table, a movable tool tray for core material, an abutment angle, and a cutting tool cooling system (Prospect ZAO NPF TENACON , Tver, ul.2-ya Lukina, 6).

The disadvantage of this machine is the laborious installation of the core, the complexity of its fastening (it is necessary to fix 8 screws), the unreliability of fastening in the carriage, low productivity, due to the very low feed. The engine stops unable to withstand core resistance.

The objective of the utility model is to create a design that provides reliable and accurate core fastening, uniform core feeding for sawing, accuracy and uniformity of cut, complete core cutting.

The problem is solved in that in the core sawing machine, including the bed, guides, cutting tool, cutting tool cooling system, the guide is made in the form of a hollow pipe, in the body of which there is a through slot for the cutting tool, a pusher for core feeding is installed in the end of the guide or in the form of devices for sawing large core samples.

- d guide made more than the diameter of the core.

The technical result is achieved by the fact that the implementation of the guide in the form of a hollow tube with a through slot in the housing under the cutting tool provides complete cutting of the core, due to the free passage of the cutting tool into the slot to the entire core depth.

The technical result is also achieved by the fact that the execution of the guide in the form of a pipe with d slightly larger than the core being sawn ensures reliable fastening of the latter and does not require an additional mechanism for fixing the core during sawing.

The technical result is also achieved by the fact that an additional device for sawing large core samples provides reliable fastening of the latter and their full cutting.

The inventive utility model is illustrated in the drawing, where:

Figure 1 - shows a General view of the machine in section along aa.

Figure 2 is an additional device.

The core sawing machine comprises a body 1 mounted on a frame 2, a guide 3 is fixed in the body 1, in the form of a hollow pipe, with d slightly larger than the core to be sawn. In the guide body 3, a through slot 5 is made under the cutting diamond disk 6. The disk 6 is mounted on the engine drive with a fixing nut 7. The disk 6 is provided with an inlet 8 for coolant to enter the cutting disk. Core 4 serve

in the guide for cutting using the pusher 9. At the bottom of the frame 2 mounted tank 10 to drain the water. A collector for sludge is fixed at the end of the guide 11. The machine is additionally equipped with a device 12 for sawing large samples 13, containing clamping planes 14 and a latch 15.

The machine operates as follows.

A core sample 4 is placed in the guide 3, with d slightly larger than the core being sawn, which contributes to its reliable fixation in the guide, and the cut line and depth are established. Connect the supply of coolant 8 to the cutting disk 6 and turn on the drive motor of the cutting tool. The pusher 9 advance the core 4 in the guide 3 to the disk 6 and sawing. Water supplied to the disk 6 enters the drain tank 10, and the resulting sludge enters the sludge collector 11.

In the case of sawing large samples, the machine is equipped with a device 12. A large sample 13 is placed between the clamping planes 14 and secured with a latch 15. The device is brought under the cutting tool 6 and the sample is cut. When sawing, guide 3 is replaced by special tool 12.

The execution of the guide in the form of a hollow pipe with d is slightly larger than the core being sawn, provides reliable fastening of the latter, and does not require an additional mechanism for fixing the core during sawing.

The pusher provides uniform and smooth core feed for sawing.

An additional device for sawing large samples provides reliable fastening of the latter and their full cutting.
