Description

A kind of cutter

Technical field

The present invention relates to cutter field, particularly relate to a kind of cutter.

Background technology

Along with improving constantly of Machining Technology, the requirement of process tool used also improves constantly therewith, do not require nothing more than cutting knife sharp, cutting speed, cutting degree, also require that cutting is neat, quality to cutting, improving constantly of required precision, to improving production efficiency, reduce production cost, the requirement of the surface trimming function with high-intelligentization is also promoting, at present, some large-scale automatic rulecutter structures are complicated, production cost is high, it is not appropriate for promoting the use of on a large scale, and some small-sized cutter machine automaticities are low, production efficiency is low, so when producing product, need bigger labour force.

In mechanical processing process, cutting usual way has the cutting of hand cut, semi auto cutting machine and numerical control cutting machine cutting, hand cut is flexible, but hand cut is of poor quality, scale error is big, waste of material is big, following process workload big, labor condition is severe simultaneously, and production efficiency is low, copying cutting machine in semi auto cutting machine, the quality of cutting workpiece is better, owing to it uses cutting die, is not suitable for single-piece, small lot and big work piece cut.Although other type semi auto cutting machine reduces labor strength, but its function is simple, is only suitable for the part cutting of some relatively regular shapes.

Use hand cut and semi-automatic cutting mode also comparatively general in some medium-sized and small enterprises of China are even at some large enterprises, such as, the commonly used sawtooth of workman cuts trees or green stem, sawtooth cuts through every time all can remove some little chips, need blade repeatedly to cut through and could cut off stem, extend clipping time.In addition, instrument must be exerted oneself by operator, compress stem, to keep cutting, this hands that can make operator and/or arm are tired, simultaneously, there is the little easy deflection of stem of weak support or be booked between sawtooth, therefore can not effectively be cut, therefore cutting efficiency is effectively improved, cut quality, alleviate operator ground labor intensity and seem particularly necessary, but, it is irregular that hand cut and the such cutting of semi-automatic cutting mode easily cause cutting, facet out-of-flatness, cause and tear, cut material has shredding or residue, cutting effect cannot be fine, cut material needs cutting tool is firmly waited to be stranded.

In sum, for the shortcoming of above-mentioned cutting knife, present configuration is simple, with low cost, cuts convenience and high-efficiency, and time saving and energy saving, cut quality is good, it is possible to the obstinate object of cutting.
