Fret saw cutting device

Abstract

The invention discloses a fret saw cutting device which comprises a fret saw frame and a locating clamp. Fret saws are arranged on the fret saw frame side by side, the fret saw frame can be driven by a fret saw frame driving mechanism to drive the fret saws to reciprocate linearly, and the locating clamp is driven by a clamp driving mechanism to move on the horizontal plane. The fret saw cutting device can be used for cutting multi-dimensional products in large scale, and the producing efficiency is greatly improved. When being arranged in the oxygen controlling equipment, the fret saw cutting device can be applied to near-net processing of green compact of special materials especially rare-earth permanent magnetic materials and can prevent the materials from being oxidized in processing.

Description

technical field [0001] The invention relates to a wire saw cutting device, which belongs to the field of processing equipment and is used for cutting and processing various parts and products, especially for processing rare earth permanent magnet materials. Background technique [0002] Existing wire-cutting equipment generally has a single cutting wire reciprocatingly moving for cutting, such as a rotary ultrasonic vibration wire-cutting device disclosed in Chinese patent document CN203957169U, which includes a bed, a longitudinally moving working platform, a laterally moving working platform, Workpiece support, C-shaped wire saw rack, diamond wire saw, up and down ultrasonic vibration device, up and down rotating motor, up and down power transmission device, wire saw preload device, wire saw reciprocating mechanism, ultrasonic generator and electrical control device. The upper and lower ultrasonic vibration devices are respectively fixed on the upper and lower working arms...

AI Technical Summary

Problems solved by technology

[0004] The reciprocating motion of a single cutting line can only meet the processing requirements of a workpiece at one position, and cannot simultaneously process multiple workpieces at multiple positions; moreover, it uses screw drive to control the reciprocating motion mechanism of the wire saw to drive the cutting line. Reciprocating motion, such a driving method is inefficient, so generally speaking, the overall processing efficiency of the reciprocating motion of a single cutting line is low, which cannot meet the processing needs of mass products

[0005] However, the wire net with single-wire reciprocating winding stroke can realize multi-wire cutting, but due to the limitation of its structure, it can generally cut about 10 workpieces at the same time, but the equipment structure is relatively complicated; and if more than 20 workpieces are cut at the same time workpiece, the equipment of which will be very large
