Description

Ultrasonic wire cutting wheel

Technical Field

The utility model relates to a wire-electrode cutting wheel is a cutting wheel of using among the wire-electrode cutting, belongs to buddha's warrior attendant line and molybdenum wire spark-erosion cutting technical field.

Background

At present, diamond wire cutting is often used for cutting silicon carbide, ceramics, and the like. The existing diamond wire cutting has the following defects: because the hardness such as carborundum, pottery is big, cutting speed is slow, and cutting efficiency is low, and buddha's warrior attendant line life is short, and the processing cost is high, and current buddha's warrior attendant line cutting mode cutting plane is not smooth moreover, and the cutting position has stress, easily appears defects such as edge breakage, influences processingquality. The metal precision cutting also adopts an electric spark processing mode mostly, the cutting speed is low, the cutting surface is rough, the workpiece is easy to deform and the like, and the subsequent precision machining difficulty and cost are increased seriously.

Disclosure of Invention

To the above-mentioned defect that exists among the prior art, the utility model provides a can improve line cutting speed, improve cutting quality and can improve line of cut life's ultrasonic wire cut electrical discharge machining wheel.

The utility model discloses a realize through following technical scheme: the utility model provides an ultrasonic wire cut electrical discharge machining wheel, includes the cutting wheel body, characterized by: a plurality of ultrasonic generators are fixedly arranged in the wheel disc of the cutting wheel body along the circumferential direction and are arranged along the radial direction of the cutting wheel body.

The utility model discloses the during operation, supersonic generator act on the line of cut through high-frequency vibration, and the line of cut cuts the work piece in high-frequency vibration, can improve the cutting speed of line of cut, improves cutting efficiency, has prolonged the life of line of cut simultaneously. In addition, the cutting surface of the cutting line with high-frequency vibration is smoother, and meanwhile, the cutting stress can be effectively removed through the high-frequency vibration of the cutting line, so that the conditions that the edge is broken and the cut removal objects are prevented from being attached to the cutting line in the cutting process can be effectively prevented. The principle is as follows: the ultrasonic linear cutting processing is a mode of cutting processing by using a diamond wire or a molybdenum wire as an ultrasonic carrier, vibration is carried out for more than ten thousand times per second, an ultrasonic cavitation effect is generated before a cutting line is contacted with a workpiece to release a large amount of energy, the hardness of the cutting plane is instantly reduced to remove cut objects more easily, chips are not attached to the surface of the cutting line during cutting due to high-frequency vibration cutting, the cutting speed is greatly improved, and meanwhile, synchronous correction is carried out on the cutting plane, and the slow wire cutting effect is achieved.

Preferably, the number of the ultrasonic generators is 6 or 12 which are uniformly arranged.

Preferably, a screw is arranged in the middle of the ultrasonic generator, and the ultrasonic generator is fixedly connected with the cutting wheel body through the screw.

Preferably, a groove is formed in the rim of the cutting wheel body, and a polyurethane rim with a wire groove is arranged in the groove. The polyurethane rim has the advantages of wear resistance and capability of protecting cutting lines, and the wire grooves in the polyurethane rim are used for positioning the cutting lines.

The utility model has the advantages that: the utility model discloses a fixedly set up a plurality of supersonic generator along circumference in the rim plate of cutting wheel body, utilize supersonic generator's high-frequency vibration to act on the line of cut, the line of cut cuts the work piece in high-frequency vibration, can improve the cutting speed of line of cut, has improved cutting efficiency, has also prolonged the life of line of cut simultaneously, is favorable to reducing the processing cost; adopt in addition the utility model discloses the cutting workpiece cutting plane is more smooth, can effectively get rid of cutting stress through the high-frequency vibration of line of cut simultaneously, can prevent effectively that the cutting process from appearing collapsing the limit and stopping the cutting and get rid of the condition on the thing adheres to the line of cut, and the work piece breakage rate can reduce to 1-3%, is far less than and adopts conventional technique to add 27% breakage rate man-hour, can improve processingquality greatly, reduces the processing cost.
