BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for post-treatment of metal products, and more particularly, to an chamfering device for removing burrs of a circular product for easily and quickly cutting burrs generated when forging a circular metal product. .

When forging or casting metal materials or injection molding synthetic resin materials, especially when processing circular products by the die forging method, burrs are formed around the outermost edge of the product. You are done.

Post-processing to remove burrs as described above is usually performed by a worker using a file to manually remove the product, or by vibrating, grinding, or sand blasting the product from the abrasive. Is done.

Burrs may also be removed by rinsing the product with a variety of materials or by flushing the product with high-pressure abrasive additives.

When removing burrs, for example, if the surface of the product has to be cleaned beforehand or after the post-treatment has to be carried out, abrasives etc. are not only slow but also have a problem in that the surfaces collide with each other during post-treatment. There was.

On the other hand, the burr may be removed by chamfering using a machine tool such as a lathe, and this chamfering is performed by rotating one end of the product 2 into the chuck 4 of the lathe spindle as shown in FIG. 1. The cutting tool 6 is used to allow the beveling and deburring operations to be applied to the product 2 simultaneously.

However, in the chamfering operation using the lathe as described above, it is not easy to manufacture a chuck suitable for various products, and the work for attaching the chuck to the lathe spindle, in particular, the work for snapping the product to the chuck is not simple. In addition, work time is also long, so workability is poor, work efficiency is low, and productivity is also reduced.

In addition, the removal of the product burr located as the part where the bite tip part of the cutting tool cannot reach is inherently impossible, and if the product is chucked in reverse, the cutting plane standard is changed so that the part that should not be cut is cut. Will make the product defective.

The present invention is to solve the problems of the prior art at one time to produce a high quality product, the object of the present invention is to ultimately improve the productivity, and also to remove the burr of the prototype product to build a mass production system It is to provide a chamfering device for.

Another object of the present invention is to remove the limitation of the removal of the burr by operating the bite tip of the cutting tool in a direction perpendicular to the direction of the rotation axis, and also eliminates the problem that the cutting plane reference is different because there is no need to chuck the product in reverse The present invention is to provide a chamfering device for removing burrs of a circular product that can simultaneously solve the problem of product defects caused by cutting to the part not to be cut.
