    A cutting pick for a mining machine is described in which a plate 2 is formed on an end of a cylindrical shank 1 and a socket 8 carrying a cutting insert 3 is formed on the plate 2. The socket 8 can be generally ellipsoidal and its axis 5, which is inclined at an obtuse angle to the shank axis 4, passes through a free edge 11 of the plate 2. The cutting insert 3 may be soldered or glued in the socket, or it may be mounted in a separate bush. <IMAGE>

    专利说明:

    The invention relates to the mining industry, namely to the rock cutting tool of mining machines.
    The purpose of the invention is to increase the wear resistance of the cutters for mining machines.
    FIG. 1 shows a cutter, side view; in fig. 2 is a section A-A in FIG. one; in fig. 3 - working cutter head with rezhushey insert, longitudinal section; in fig. 4 - cutter, front view; in fig. 5 is a section BB in FIG. one.
    The cutter consists of a cylindrical holder 1, which transforms into a flat working head 2 with a cutting insert 3. The axis 4 of symmetry of the cutting insert 3 is located in the plane of symmetry of the working head 2 at an obtuse angle оС to the axis 5 of symmetry of the holder 1. The cutting insert is made of sintered carbide and has a tapered tip 6. The insert is placed in the slot 7 of the element 8 of the extension with which it is connected or stationary, for example, by soldering, gluing, etc., or with the possibility of replacement. In the second embodiment, it is possible to place the cutting insert 3 in the sleeve 9, which
    After installation in slot 7, the rue is fixed with a fuse 10, for example, a flexible pin. The broadening element 8 is made in the form of a part of the body vra, under the cutting insert 3, while the projection of the part of the body of rotation on a plane parallel to the longitudinal plane of symmetry of the working head has the form of an ellipse truncated along the major axis from the side of the cutting insert and the larger axis of the ellipse coincides with the insertion axis 4 and directed to the back face 11 of the flat head 2 cutter. To improve the attachment of the cutter in the tool holder 12, the rear face 11 can be equipped with a step 13, oriented in the direction towards the cylindrical holder 1.
    Cutting insert 3 may have another shape, for example prismatic or pyramidal.
    The forming part of the rotation body can be truncated by two mutually parallel planes 14 and 15 or planes 16 and 17 parallel to the side surfaces 18 and 19 of the flat working head 2.
