Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

As can be seen from Fig. 1, Fig. 2, Fig. 3, a kind of processing method of special-shaped emery wheel, it comprises emery wheel blank 4, forming roller 2, the curved surface 23 shape of described forming roller 2 and the curved surface 41 shape after emery wheel blank 4 processing are mirror Like; when the grinding wheel blank 4 axially rotates, the curved surface 23 of the forming roller 2 gradually approaches the curved surface 41 of the grinding wheel blank 4 and squeezes it until the curved surface 41 shape of the grinding wheel blank 4 is extruded into the shape of the forming roller 2 curved surface 23 mirror image.

The rotational speed of the grinding wheel blank 4 in the present invention is 5-50 rpm.

The rotation speed of the grinding wheel blank 4 in the present invention is preferably 15-20 rpm.

In order to improve the extrusion quality and avoid damage to the forming roller 2 during extrusion as much as possible, the forming roller 2 of the present invention includes a body 21, on which there are extruding sheets 22 arranged in a circle, and two adjacent extruding sheets 22 are arranged. Grooves 24 are arranged between the press sheets 22 , and the extrusion surfaces 25 of each extrusion sheet 22 form the curved surface 23 of the forming roller 2 .

A processing device for a special-shaped grinding wheel, which includes a frame 1, an axial sliding platform 11 is arranged on the frame 1, a radial sliding platform 8 is installed on the axial sliding platform 11, and a rotating platform driven by power is installed on the frame 1. The grinding wheel blank 4, the radial sliding platform 8 is provided with a forming roller shaft 10, the forming roller shaft 10 is equipped with a forming roller 2, the curved surface 23 of the forming roller 2 is opposite to the curved surface 41 of the grinding wheel blank 4, the forming roller 2 The shape of the curved surface 23 and the shape of the processed curved surface 41 of the grinding wheel blank 4 are mirror images.

In order to ensure the extrusion effect, the forming roller 2 of the present invention is installed on the forming roller shaft 10 through a damping sleeve 7 .

The rotational speed of the grinding wheel blank 4 in the present invention is 5-50 rpm.

The rotation speed of the grinding wheel blank 4 in the present invention is preferably 15-20 rpm.

In order to improve the extrusion quality and avoid damage to the forming roller 2 during extrusion as much as possible, the forming roller 2 of the present invention includes a body 21 installed on the forming roller shaft 10, and the body 21 is provided with extrusion rollers arranged in a circle. The sheets 22 are provided with grooves 24 between two adjacent extrusion sheets 22 , and the extrusion surfaces 25 of each extrusion sheet 22 form the curved surface 23 of the forming roller 2 .

According to the required shape of the curved surface 41 of the special-shaped emery wheel 4, the present invention first processes the forming roller 2, and on a piece of cylindrical metal, its curved surface shape is processed into a mirror image with the shape of the special-shaped emery wheel 4 curved surface 41, and then, Slots are made from the curved surface toward the center, so that extruded sheets 22 and grooves 24 are staggered.
