Abstract

Provided is a coating film cutting rotary tool in which high efficiency and low cost are given top priority. SOLUTION: Since the edge as a blade portion is formed in an arc shape with a plurality of cutting tips installed on the outer peripheral edge portion of the base metal, it is possible to cut by biting with less resistance to a thick coating film, The ability to far exceed the conventional work and the physical fatigue due to noise and vibration generated from the machine to the worker are also extremely reduced. In addition to operability, the finishing accuracy is high, and the cost can be fully met. [Selection] Figure 1

Description

  The present invention relates to a coating film cutting rotary tool used for removing a coating film on the surface of an iron part.

  In the renovation work of iron building structures, thick coatings by repainting can be done manually with a scraper, chiseling with a chiseling machine, etc., or with a grindstone attached to an electric rotating machine (grinder). Since it is conducted in the mainstream, labor costs are high with low efficiency.

Problems that the device tries to solve

  The present invention is a coating film cutting rotary tool devised for the purpose of giving high efficiency and low cost the highest priority in view of the above circumstances.

Means for solving the problem

  In the present invention, since the plurality of cutting tips installed at the outer peripheral edge of the base metal have arcuate edges, the thick coating can be cut with little resistance.

  It is preferable that a wear-resistant layer having higher wear resistance than the chip body is provided on the front surface of the cutting tip. The wear-resistant layer is preferably composed of a diamond sintered body. The wear-resistant layer is preferably composed of an ultra-low grain layer in which ultra-low grains are fixed with a pound material. If it does in this way, the lifetime improvement of the coating-film cutting rotary tool is achieved.

  It is preferable that the coating film cutting rotary tool includes a chip discharging portion formed by cutting out a base metal in front of the cutting tip. If it does in this way, the chip | tip shaved with the cutting tip will be discharged | emitted back through a cutting tip from a chip | tip discharge part. Thereby, the chip is promoted and clogging of the cutting tip can be eliminated.

Form of device

  Hereinafter, the form of the coating film cutting rotary tool of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front sectional view of (1) an electric rotating machine (grinder) attached with a (2) coating film cutting rotary tool of the present invention. 2 is a bottom view of the coating film cutting rotary tool (2) in FIG. FIG. 3 is a top view of FIG. FIG. 4 is a perspective view of FIG. FIG. 5 is an enlarged view of (3) the cutting tip of FIG.

Example of device

Hereinafter, embodiments of the coating film cutting rotary tool of the present invention will be described with reference to the accompanying drawings. FIG. 6 is a view of cutting an iron coating film by attaching a coating film cutting rotary tool of the present invention to (1) an electric rotating machine (grinder). FIG. 7 is an enlarged view after cutting the coating film of FIG. It is the figure which is cutting so that the coating film of an iron part may be cut as shown in FIG. 6 and FIG.

Effect of device

  As described above, the coating film cutting rotary tool of the present invention has a far greater ability than the conventional work and the physical fatigue due to noise and vibration generated from the machine to the worker. Is. Moreover, not only the operability but also the finishing accuracy is high, and the cost can be sufficiently met.
