摘要:
A surface finishing apparatus for in-line outer surface polishing of elongate cylindrical metal stock to apply a long scratch finish, including a stock feeder for feeding a length of stock through the finishing apparatus from an infeed downstream to an outfeed position while rotating the stock about its longitudinal axis and a polishing assembly for finish-treating the outer surface of the stock as the stock is fed through the apparatus to apply a long scratch finish thereto. The polishing assembly includes a rotatable finishing wheel having a finish-treating peripheral surface for being applied in an in-line orientation against the outer surface of the stock as the stock is simultaneously fed and rotated through the finishing apparatus. The finishing wheel is mounted on an axis of rotation which is perpendicular to the longitudinal axis of the stock, and is rotated at a speed sufficiently great in comparison to the speed of rotation of the stock that the scratch finish applied to the stock is linear and extends substantially along the longitudinal axis of the stock.

An abrading apparatus for cleaning an outer surface of an elongate member, such as a wire. An endless abrasive sanding belt is rotated about a plurality of rollers and orbited about the elongate member. Drive components for both rotating the belt about the rollers as well as orbiting the belt about the elongate member are isolated in an enclosed drive casing containing lubricating fluid, such as oil. A first roller which mounts the endless sanding belt is fixed in a rotatable eccentric support. This eccentric support allows the tension of the endless belt to be adjusted by rotating the eccentric support in one of two directions. One of the rollers includes a mounting portion and a belt supporting portion, with the mounting portion being axially offset or eccentric with respect to the belt supporting portion. A belt engagement and disengagement mechanism is connected to the eccentric mounting portion of the idler roller to allow rotation of the eccentric mounting portion in two directions.

A vertically adjustable support frame (10) with chain clamps (12) supports a mold (14) containing an ingot (16) in alignment with a ram cylinder (18). Rolls (34) receive the ingot and transfer it to rolling rolls (38). A belt grinder (46) traverses the length of the rotating ingot to grind the circumference.

An inline-ready method of finishing the surface of a long material (W) capable of preventing any environmental problem from occurring and the mechanical properties of the long material from deteriorating, comprising the steps of holding the long material (W) by two or more elastic endless belts (1) with a specified force, rotating the elastic endless belts (1) in the same direction as or in the reverse direction to the moving direction of the long material by moving the long material (W) and increasing or decreasing the rotating speed of the elastic endless belts (1) more than or less than the moving speed of the long material, and loading powder and granular grinding material (S) between the elastic endless belts (1), characterized in that the grinding material (S) is moved relative to the long material (W) to rub the grinding material (S) against the long material (W) so as to finish the surface of the long material (W).

In a power grinder (1) with a motor (6) and a gear (7) that drive an oscillating drive means (2), which moves a grinding belt (3) secured to it to reciprocate, a simple change of the grinding belt (3) is made possible by providing that the grinding belt (3) has a hook-and-loop closure (4), or the grinding belt (3) is disposed with its first end (11) on the drive means (2), and its second end (12) is connected to a handle (13).
摘要:
This invention relates to a cylindrical workpiece sanding machine which includes a plurality of workpiece driving heads for advancing a piece to be sanded through a sanding operation. Each of the workpiece driving heads includes a pair of shaped rollers biased into engagement with the workpiece, a drive train for rotating the rollers about a respective roller axis to advance the workpiece along its axis and for simultaneously rotating the rollers about the workpiece axis thereby spirally advancing the workpiece. A plurality of abrading belts are located on the sanding machine with means for driving an abrading surface on each of the belts adjacent the workpiece advancing axis.
