Manual emery wire cutting machine

Abstract

The invention provides a manual emery wire cutting machine. The manual emery wire cutting machine comprises a machine body, a gear transmission device, a crank slide block guide rod mechanism, wire winding and unwinding devices, a fixed supporting and float pressing device, a wire carrying mechanism and a fixed worktable. The whole working process is as follows: a motor drives a driving gear to rotate to enable two working gears, engaged with the driving gear up and down and with the same geometric sizes, to rotate; crank shafts with a phase difference of 180 degrees and the same eccentric distance are respectively mounted on the working gears; through connection of rolling bearings and slide block guide rods, the rotating motion of the working gears is converted to the linear reciprocating motion of the upper and lower slide block guide rods; meanwhile, the slide block guide rods are provided with the wire winding and unwinding devices for fixing, replacing and changing working sections of emery wires; and nonmetal plates are pressed by the float pressing and fixed supporting device, so that the instant advancing motion distance and speed of the emery wires mounted on the upper and lower slide block guide rods are equal to the instant retreating motion distance and speed, and the reciprocating cutting of nonmetal workpieces is finished.

Description

technical field [0001] The invention is a novel manual diamond wire cutting machine aimed at cutting non-metal plates, especially composite material plates, and belongs to the field of processing non-metal plates, especially composite material plates. Background technique [0002] Nowadays, cutting machines for non-metallic plates, especially composite material plates, are very rare in the market, and cutting machines for cutting non-metallic plates into various shapes are even rarer. At present, most of them are cut with manual toothless saws. This cutting method has low efficiency, large processing errors, poor cutting stability, and relatively low quality; the application number is CN201610804880.7 A kind of diamond wire cutting machine for composite material plates, its wire feeding mechanism is relatively complicated, processing and debugging are difficult, and uneconomical When working, it is easy to form a pile of wires at the incision and the tension of the sanding l...
