Problems solved by technology

[0009] However, when the surface to be processed deviates from the center of rotation, depending on the shape of the workpiece and the type of machine used, such as the machining center, there may be a problem that the workpiece cannot be rotated or rolling processing cannot be performed.

Embodiment Construction

[0061] The best mode for carrying out the present invention will be described in detail below with reference to the accompanying drawings.

[0062] 1 is a cross-sectional view showing the structure of a tumbling tool for machining a corner R surface of a cylindrical outer peripheral step portion according to a first embodiment of the present invention.

[0063] As shown in FIG. 1 , the tumbling tool 1 of the present embodiment has a handle 3 for attachment to a processing machine such as a lathe. The shank 3 is composed of, for example, a tapered insertion portion 3a and a cylindrical body portion 3b. The tapered insertion portion 3a is a Morse taper for mounting on a processing machine such as an NC lathe. On the other hand, one end of the main body part 3b is open and the other end is closed in order to accommodate the below-mentioned urging device, the spindle, the positioner 6, etc. in the cylindrical main body part 3b.

[0064] In this embodiment, for example, three rol...

Abstract

The present invention provides a rolling tool capable of processing a corner R surface by turning a tool in addition to turning a workpiece. The rolling tool is characterized in that it includes: a roller (5); a handle (3); a locator (6), which is used to accommodate the roller and enable the roller to rotate freely and in a preset inclination direction move upward; mandrels (12), (14), which hold the locator (6), enable the locator to rotate freely and slide freely in the axial direction, and form a roughly " <"-shaped recess (12a); the first force applying device (10) applies a force towards the front of the tool to the locator (6), and the rolling tool also has a mechanism for adjusting the machining diameter of the tool through the following actions, namely By pressing the roller (5) to the workpiece, the positioner retreats, and the roller (5) moves along the shape of the recess (12a) formed in the mandrel (12).

Description

technical field [0001] The present invention relates to a rolling tool for rolling processing, especially a rolling tool capable of processing corner R surface through tool rotation in addition to workpiece rotation. Background technique [0002] Generally speaking, the surface processed by cutting has a limit in roughness, that is, there are turning lines formed by the so-called peaks and valleys. Therefore, not only will there be problems in performance such as mechanical strength, but also the appearance will be affected. Therefore, the following processing is generally performed: After cutting, rolling processing is performed to greatly improve the surface roughness, so that the surface is as smooth as a mirror. [0003] The principle of rolling processing is: use rollers to roll the metal surface, flatten the "peak part" and make the processed surface smooth, which is a kind of plastic processing method. Unlike grinding, it can improve the surface roughness in a short...
