Technical Field

The invention is applied to the field of metal processing, and particularly relates to an automatic chip removing method for metal processing.

Background

A lot of scrap irons can be generated in the metal processing process, the scrap irons are cleaned by adopting the traditional method at present, namely, the scrap irons are continuously accumulated, the machine is stopped for cleaning every time of processing, and the production efficiency is greatly influenced. Meanwhile, in the process of machining the lathe, the iron chips are too long and always wound on the workpiece and the cutter, so that the size precision and the finish degree of the workpiece are affected, the service life of the cutter is also shortened, the condition of one hour of machining and half an hour of cutter cleaning can often occur, the machining efficiency is seriously affected, even the product is slightly assembled and is easy to fly, and the injury to personnel and equipment is caused. And when the lathe operator is at the piece filth of clearance part surface, adopt high-pressure air gun to blow usually, this can make the piece filth fly around in disorder, both cause the pollution of ground, lathe and have the potential safety hazard again, and the piece flies into operator's eyes easily and causes the injury.

Therefore, the existing scrap iron cleaning mode can seriously affect the sanitary condition inside the lathe, so that the clean production cannot be realized, meanwhile, the scrap iron is continuously accumulated, the production safety and the production efficiency can be affected, and because machine tool operators belong to high-grade technicians, the time value is high, and a large amount of time is taken out every class to clean the scrap iron, so that the waste is also great.

Detailed Description

As further described in the following, the automatic chip removing method for metal processing includes the following steps: a high-pressure nozzle facing the workpiece machining position is arranged, the high-pressure nozzle is controlled to blow chips during machining, the chips are blown to the machining position side by the high-pressure nozzle, and the chip blowing water pressure of the high-pressure nozzle is preferably 25-30 kilograms; the high-pressure spray head is adjustable in angle so as to have at least two chip blowing angles, so that chips can be better aligned and washed; the machining revolution and the feeding amount are set and controlled according to the workpiece, so that chip breaking is realized, the size (namely the thickness and the length of chips) and the chip removal direction are adjusted, and the chips can be effectively cleaned in real time by matching with the blowing of a high-pressure nozzle;

arranging a chip hooking cutter for removing chips on the surface of the workpiece, wherein the chip hooking cutter travels along the same path of the machining cutter after the machining cutter finishes operation; the path of the machining tool is simulated through a chip hooking cutter, and chips wound on a workpiece are hooked; meanwhile, the selection of the cutter is optimized on the original basis, for example, the external groove rough turning cutter selects the R-direction cutter as much as possible, the cutting chips are easier to directly drop, and the problem of workpiece winding and cutting is effectively solved;

after the workpiece is machined, a cleaning program is started, the workpiece and the tool clamp are washed by spraying water above the main shaft, the cleanliness of the surface of the workpiece and the tool clamp is guaranteed, impurities affecting clamping precision are removed, and the quality of a product is guaranteed stably for a long time. The cleaning action is debugged and optimized by writing a cleaning program, and the water pressure of water sprayed above the main shaft is in the range of 50-100Bar, preferably 70 Bar.

Blowing chips through a high-pressure nozzle during machining, and controlling the machining revolution and the feeding amount so as to adjust the size and the chip discharging direction of the chips; meanwhile, the chip hooking cutter for removing chips on the surface of the workpiece is further arranged, the chip hooking cutter advances along the same path of the machining cutter after the machining cutter finishes operation and hooks the chips wound on the workpiece, so that automatic chip removal inside a machine tool is realized, manual cleaning during stopping is not needed, and the chip hooking cutter is convenient, efficient and safe.
