Embodiment Construction

[0027] A laser continuous cutting device and cutting method, based on numerical control motion synthesis, can realize high-precision laser sawtooth continuous cutting, such as figure 1 and 3 As shown, the specific cutting process is as follows:

[0028] 1) During the whole working process, the bimetal strip feeds in one direction at a constant speed;

[0029] 2), the code detector is fixed as a machine tool coordinate ( x 3 ,y 3 ), used to detect the feed length of the saw band, the starting cutting position of the laser head is A ( x 1 ,y 1 ), the position of the laser head after each cutting is B ( x 2 ,y 2 );

[0030] 3) The position where laser cutting is completed is the tooth tip position. After cutting a group of teeth (or groups of teeth), the laser head quickly returns to the starting point A(x1, y1);

[0031] 4) After the laser head returns to the cutting start point A(x1, y1), prepare for a new round of cutting;

[0032] 5) At this time, the displacem...

Abstract

The invention discloses a laser continuous cutting device used for cutting a saw belt and a cutting method. The laser continuous cutting device aims to solve the problems that continuous cutting and forming of sawteeth can not be achieved, tool auxiliary time accounts for a high percentage, and cutting efficiency is low in the prior art. The laser continuous cutting device comprises a base which is sequentially provided with a driving friction roller used for regulating feeding speed of the saw belt, a pressing wheel set used for pressing the saw belt, a work platform and a driving wheel set driven by a driving device; a laser head which is arranged on a Z shaft for cutting the saw belt is arranged above the work platform; the work platform is provided with a feeler block and a transverse locating mechanism used for locating the saw belt; during cutting work, the speed of a sliding platform X1 is the same as the feeding speed of the saw belt. The laser cutting sawtooth continuous forming technique does not need a milling cutter, and the sawteeth in any two-dimensional shapes can be correspondingly manufactured very rapidly.

Description

technical field [0001] The invention relates to a laser continuous cutting device and a cutting method for cutting saw bands, which are mainly applied to the formation of saw teeth of bimetallic band saw blades. Background technique [0002] As the main method of metal cutting, band saw cutting has been widely used in various industries of metal processing. As for the sawtooth forming method of the band saw, the method of forming and milling is generally used. Among them, the cost of milling teeth mainly comes from the depreciation of milling machines and milling cutters; secondly, the sawtooth shape formed by milling teeth is limited and the cutting edge of milling cutter and its space trajectory make it difficult to form some irregular special-shaped teeth; In the current market, the response cycle of the milling process is too long; the production and manufacturing cycle of milling cutters is generally more than 2 months, and each milling cutter generally needs to be pro...
