rotary cutting machine

Abstract

To provide a peeling machine being able to easily and swiftly conduct production process and preparation work, excellent in durability, and able to certainly prevent movement of a tool holder to a radial inner side by self weight, a peeling machine is provided with a rotation cylinder 1 to which a work W of round rod is inserted, a tool holder 22 attached to the rotation cylinder 1 as to freely slide along a radial direction R of the rotation cylinder 1, and a pressing member 3 attached to the rotation cylinder 1 as to freely slide along an axial direction X of the rotation cylinder 1; and constructed as that a pressing face 32a of the pressing member 3 and a pressure-receiving face 22a of the tool holder 22 are made sliding with inclination on a longitudinal face parallel to a sliding direction Y of the tool holder 22, and the tool holder 22 is made sliding to a radial inner side Rb on the longitudinal face by sliding the pressing member 3 to an axial outer side Xa; and, a hook member 6, hitching the tool holder 22 as to prevent sliding of the tool holder 22 to the radial inner side Rb by self weight, is attached to the pressing member 3.

Description

technical field [0001] The present invention relates to rotary cutters. Background technique [0002] There is a conventional rotary cutting machine as follows: a rotating cylinder through which a round rod-shaped workpiece is inserted, and a tool holder mounted on the rotating cylinder so as to be slidable in the radial direction of the rotating cylinder (for example, Refer to Patent Document 1). [0003] Such as Figure 7 As shown, such a conventional rotary cutting mechanism is provided with a pressing member 93 mounted on the rotating cylinder 90 and slidable in the axial direction X of the rotating cylinder 90, and the pressing surface 93a of the pressing member 93 is aligned with the tool holder 92. The pressing receiving surface 92a of the tool holder 92 is in oblique sliding contact in a longitudinal section parallel to the sliding direction Y of the tool holder 92, and the pressing member 93 slides to the axially outer side Xa, whereby the tool holder 92 moves radi...

Problems solved by technology

[0006] However, a large rotary cutting machine that cuts workpieces with a diameter exceeding 100 mm has a large and heavy tool holder, so a coil spring with strong elasticity is used, and there is a problem in the manufacturing process and preparation work before the cutting operation: it is difficult to confirm the tool holder. Whether it can slide smoothly or not, and it takes time and effort to manufacture due to the complexity of the structure

[0007] In addition, the tool holder is pushed while the pressing member is in sliding contact with the tool holder with a strong force against the elastic force of the coil spring, so there is a problem that the pressing surface of the pressing member and the pressing receiving surface of the tool holder are easily generated. wear problem

[0008] Furthermore, when the tool holder is moved radially outward in order to cut a workpiece with a larger diameter than the previous cutting operation, if the sliding resistance of the tool holder increases due to fine chips, the tool holder cannot move in the spiral direction. The elastic force of the spring moves outward in the radial direction, and if a workpiece with a larger diameter than the previous cutting operation is fed while the tool holder cannot be avoided, the end of the workpiece may come into contact with the tool holder. problems such as deformation and damage
