Abstract

The invention relates to the processing of materials by cutting and can be used for crushing chips in turning operations. The aim of the invention is to increase the reliability of the crushing process. For this, the device is equipped with a crank mechanism, on the slider 1 of which the body 2 is fixed with the L-shaped lever 4 hinged in it, the cutting element 9 is placed on the smaller arm, and the larger arm has the ability to interact with the limiter 7. In the process, the body 2 performs reciprocating movements, as a result of which the chips fall into the gap between the housing and the cutting element 9 and are either cut or detached from the workpiece. 1 il.

The invention relates to the field of machining materials by cutting and can be used for crushing chips in turning operations.

The aim of the invention is to increase the reliability of the crushing process,

The drawing shows a diagram of the proposed device.

The chip crushing device consists of 1 case 2 fixed on the slider with a stand 3 placed on its inner surface, on which the L-shaped lever 4 is rotated, the larger arm 5 of which is spring-loaded relative to the case by the elastic element 6 and has the ability interacting with the limiter 7 fixed on the housing of the angular rotation of the lever, and the smaller arm 8 is provided with a cutting element 9. In this case, the slider 1 is installed in the fixed guides 10 and is kinematically connected by means of the connecting rod 11 to the crank 12, placing nnym rotatably from autonomous drive (not shown) on a rack 13,

The device is located in the cutting area of the lathe in the immediate vicinity of the cutting tool 14,

The device works as follows.

8, the process of rotating the crank 12 of the slider 1 with the housing 2 installed on it makes reciprocating movements, periodically approaching the root zone formed during the processing of the workpiece 15, the chips 16.

when the body 2 moves to the workpiece 15, the chips 16, acting on a smaller p-in. 8 G-squeeze lever 4, rotates it within the amount of deformation of the elastic element 6 and passes into the gap formed between the cutting element 9 and the surface of the body 2. and at the reverse movement of the slider 1 at a speed exceeding the speed of chip flow, the latter is gripped by the lever 4, which, turning under the action of the elastic element 6 and the friction forces between the surfaces of the chip and the cutting element 9, is last affected by the chip, or cuts or opens it. In this case, limiter 7 prevents further rotation of the lever 4 and splintering of the chips.

The cycle of operation of the device is repeated in the sequence indicated.

Claims (1)

Claims A chip breaking device including a cutting element mounted in a housing that is movable, characterized in that, in order to increase the reliability of the crushing process, the device is equipped with a crank-pinion mechanism, the housing being fixed on the slider of said mechanism, and the cutting the element is placed on the smaller arm of an L-shaped spring-loaded lever inserted into the device, the larger arm of which has the ability to interact with the device fixed to the body of the restrictor inserted into the device its cornering teleme.
