Cutting tool for cutting the center piece

The device according to the invention cuts the detrimental center piece resulting from the cutting-5 turning, which remains at the end of the detachable part when the part is cut from the rod by turning with a plug blade. Traditionally, the lump has been removed, for example, by grinding with a bench or belt grinder. The work is then relatively slow because grinding 10 is not a very efficient method compared to cutting.

The relatively small diameter of the piece causes a large point surface pressure in the grinder, whereby the abrasive wears out quickly. When sanding, it is difficult to judge the departure of a piece, so it is difficult to get a quality result. The method is also slow, noisy and dusty.

British Patent Application Publication No. 2,002,669 discloses a rod or pipe cutting device in which the removal of trimmers such as a nipple is taken into account. In the device in question, this cleaning work is carried out in a device separate from the cutting device, which is installed in connection with the cutting device. The functions of the device are automated so that the transfer of the cut part to the post-processing device 25 takes place automatically. However, no more detailed description of the structure of the after-treatment device has been provided.

. ·; ·. The essential features of the cutting device 30 which is the subject of the invention appear from the appended claim.

The device according to the invention removes the pieces very quickly: “and accurately with modest professionalism. If the surface quality requirement for the 35 cutting points in question is very high: it is preferable to remove the piece with the device in question. after that, surface finishing can be performed in a manner that requires quality. A counter indicating the number of 2 100095 pieces can also be connected to the device. The device can be used to machine rotating parts of different shapes and sizes.

In the following, the invention will be described in more detail with reference to the accompanying drawing.

A blade 3 is embedded in the slide 2 of the device according to the invention. It is advantageous to use a carbide turning blade as the blade.

The chest angle of the blade should be relatively large and play) the edge of the formula sharp without a protective chamfer when the piece needs to be removed very carefully. As the blade material, any blade material can be selected according to the requirement of the material to be processed. For the slide 2, the movement is obtained from the power source 7. The movement should be relatively fast, because then a better result is obtained. For example, a pneumatic, electric, hydraulic or muscle-based solution can be used as the power source. The movement of the slider can be either rectilinear or circular. The part rests on the slide during cutting. The impulse required to start the movement of the slider is obtained, for example, by pressing the impulse valve 6 on the body. The starting can also take place with a foot or manual switch. The front of the skate should have a narrow groove in front of the cutting direction of the 8 blades. The piece 25 in the body is placed in a groove from which it can be cut after cutting: from below. An adjustment can be made to the mounting of the response or power source. In this case, a wide::: movement can cover a wide diameter area. It is clear that the drawing and the description have arrived at a simplified operating model. Various variations of the device can be constructed in terms of different slides, stops, body blades, device size, power sources and piece input, taking into account the description and the claim.
