Abrasive belt shaping and grinding apparatus

Abstract

The invention relates to an abrasive belt shaping and grinding apparatus, in particular to an abrasive belt shaping and grinding apparatus in a knife-scissors mechanical belt sander. The invention discloses an abrasive belt shaping and grinding apparatus that comprises a frame on which a lateral feeding device and a support base are disposed. A reciprocating device is disposed on the support base.A lifting feeding device is disposed on the lateral feeding device. A rotary feeding device is disposed on the lifting feeding device and is provided with a rotary grinding head. An abrasive belt moves in lateral, lifting and rotating axial directions, and can grind a workpiece with an arc at the tangent point of the arc. The left side, the top side and the right side of the workpiece can be machined simultaneously by being clamped once.

Problems solved by technology

[0002] At present, many hardware parts are punched out by punching machines. In the workpieces punched out by punching machines, the outer contours have many burrs, unevenness, and roughness. They are all very rough. The back shaping of the knife and scissors is divided into mechanical shaping and manual shaping. There are many problems in mechanical shaping, especially small knives with relatively small arcs. It is even more difficult to process, so most of them use manual shaping. Now There is a kind of backing machine whose grinding head moves in the lifting direction, the workpiece can rotate in the vertical direction, but cannot rotate in the horizontal direction, that is, the grinding head and the worktable can be linked, but its disadvantages are It has high performance requirements for the system, difficult programming, high cost, and difficult to promote. There is also a backing machine whose grinding head is fixed to move up and down, and the workpiece is placed flat on the workbench. When processing workpieces with arcs, At the beginning, the cutting point on the cutting wheel is on the quadrant point. When cutting to a place with an arc, there will be problems at the tangent point of the arc. Gradually, the cutting point on the cutting wheel begins to deviate from the quadrant point. At this time, some arcs of the processed workpieces are small, some are high, and some are low. How to program and operate is a difficult problem.
