Abstract

PURPOSE:To make polishing operation for a projecting part in a metal mold or the like ever so easy as well as to aim at improvements in operation efficiency, by pressing a polishing body, having elasticity and holding abrasives on its outer surface, forcibly to a work after being turned round its axis. CONSTITUTION:Both ends of a rotary shaft 2 are rotatably pivotted on each of bearing parts 1a and 1b of a handle 1, while a polishing body 10 to rotate solidly with the shaft 2 is locked to a central part of the shaft 2. And the body 10 consists of a shell body 11 at the inner side, a polishing member 12 at the outer side and air 13 being hermetically sealed in an inside empty space, and the polishing member 12 is stuck with a granular something by means of a bonding agent. In addition, a bevel gear 3 is locked to one end of the shaft 2 and usually engages another bevel gear 5 locked to the end part of a rotary shaft 4 of a motor M. Next, the motor M is rotated, and in a state that the rorary shaft 2 and the polishing body 10 are solidly rotated as one body, an operator grips and end part 1c of the handle 1, and reciprocates it in a longitudinal direction while pressing a projecting part of a metal mold W to be machined whereby the mold W is easily polishable into a uniformly smooth surface.

板が破れる等の不都合が生じる。For J5 press molds for press-forming copper plates, such as automobile bodies, it is necessary to smooth the protrusions of the mold that come into contact with the steel plate. If the protrusion cap is insufficiently polished, there will be friction between the protrusion of the mold and the copper plate to be press-formed, causing problems such as the steel plate being torn during press-forming.

A J space may be formed inside the abrasive object, or an elastic material such as a sponge may be placed in place of the space. If a space is formed, the space must be filled with a constant fluid or a fluid with a variable D, since the ω11 polishing material needs to have elasticity as a whole. Air is preferable as the fluid.If the cough fluid is the same or constant, the pressure in the space will be constant, but for example, if the valve and drainage pipe are
Adjust the fluid claw as the 4i15 configuration connected to (]0i
If the construction is such that the pressure in the space can be adjusted freely, it can be immediately adapted to the shape and size of the convex portion (or concave portion) of the mold that is the workpiece.
