Description

Technical Field

[0001] The utility model relates to the technical field of electrodes, in particular to an arc milling electrode which provides dynamic rotational power through flushing liquid. Background Art

[0002] At present, the structure of arc milling machine tools is similar to that of mechanical milling machines. The power source is an electric motor, which drives the spindle to rotate through a belt or directly connected to the spindle. However, the principle of arc milling is different from that of mechanical milling. The principle of mechanical milling is to use the rotation of the spindle to drive the tool to rotate to cut the workpiece. During the cutting process, the motor needs to provide sufficient rotational torque to generate sufficient cutting force. The principle of arc milling is to use the high temperature generated by the discharge between the tool electrode and the workpiece to instantly liquefy or vaporize the material to be cut in the discharge gap, and randomly be carried away from the discharge gap by the high-pressure cutting medium to achieve the cutting purpose.

[0003] It can be seen from the principle of arc milling that no cutting force is required during the arc milling process. The purpose of the electrode rotation during the arc milling process is to improve the arc breaking effect of the arc machining through rotational motion, to make the arc machining electrode wear evenly during the machining process, and to assist in throwing out the gasified or liquefied metal through centrifugal force. During the arc milling process, the spindle only needs to provide a small rotational power for the electrode, and there is no need to provide a large torque. In order to reduce the manufacturing cost of the arc milling machine tool and simplify the structure of the arc milling machine tool, an arc milling electrode that provides dynamic rotational power through flushing liquid is proposed. Utility Model Content

[0006] Therefore, the utility model provides an arc milling machining electrode that provides dynamic rotational power through flushing liquid, including an electrode body, the electrode body is arranged in a columnar shape and has an opening inside, a plurality of rows of horizontal through holes are arranged on the surface of the electrode body, each row of through holes is composed of a plurality of through holes, the upper part of the electrode body is open and only one vertical through hole is opened at the bottom of the electrode body.

[0007] As a further improvement of the technical solution, the horizontal through holes are evenly distributed in a circular array around the electrode body.

[0008] As a further improvement of the technical solution, the horizontal through hole is perpendicular to the axial direction of the electrode body, and the axial direction of the horizontal through hole is parallel to the tangent line of the surface of the electrode body.

[0021] It can be seen from the principle of arc milling that no cutting force is required during the arc milling process. The purpose of the electrode rotation during the arc milling process is to improve the arc breaking effect of the arc machining through rotational motion, to make the arc machining electrode wear evenly during the machining process, and to assist in throwing out the gasified or liquefied metal through centrifugal force. During the arc milling process, the spindle only needs to provide a small rotational power for the electrode, and there is no need to provide a large torque. In order to reduce the manufacturing cost of the arc milling machine tool and simplify the structure of the arc milling machine tool, an arc milling electrode that provides dynamic rotational power through flushing liquid is proposed.

[0022] like Figure 1-Figure 5 As shown, this embodiment provides an arc milling electrode that provides dynamic rotational power through flushing liquid, including an electrode body 1, the electrode body 1 is 100 mm long, the outer diameter is 20 mm, the inner diameter is 16 mm, the thickness of the bottom of the electrode body 1 is 5 mm, the electrode body 1 is arranged in a columnar shape and has an opening inside, a plurality of rows of horizontal through holes 2 are arranged on the surface of the electrode body 1, the number of rows of the plurality of horizontal through holes 2 is 6 rows, each row of through holes is composed of a plurality of through holes, the number of the plurality of horizontal through holes 2 in each row is 10, the spacing between the plurality of horizontal through holes 2 in each row is 5 mm, the upper part of the electrode body 1 is open and only one vertical through hole 3 is opened at the bottom of the electrode body 1, and the diameters of the horizontal through holes 2 and the vertical through holes 3 are 2 mm.

[0023] The improvement of this embodiment lies in that: by arranging a plurality of rows of horizontal through holes 2 on the electrode body 1, the electrode body 1 can be used to process the side wall as well as the groove, and better surface quality and higher material removal rate can be obtained when processing the side wall and the bottom surface; when there is cutting fluid, the electrode body 1 can rotate without the need for an electric motor to drive it, thereby simplifying the structure of the arc milling machine tool and reducing the cost of the arc milling machine tool; the manufacturing process is simple and the processing cost is low, and processing can be performed on an ordinary milling machine.

[0024] Considering the specific introduction of the horizontal through hole 2 and the vertical through hole 3, the second embodiment of the present utility model is shown.

[0025] Six rows of horizontal through holes 2 are evenly distributed in a circular array around the electrode body 1, each row of horizontal through holes 2 is perpendicular to the axial direction of the electrode body 1, the axial direction of the horizontal through hole 2 is parallel to the tangent of the surface of the electrode body 1, the bottom vertical through hole 3 has the same aperture as the horizontal through hole 2, the vertical through hole 3 and the central axis of the vertical through hole 3 coincide with the central axis of the electrode body 1. When the electrode body 1 is processed, the cutting fluid enters from the opening on the upper part of the electrode body 1 and rushes out through the horizontal through hole 2 and the vertical through hole 3 of the electrode body 1. The cutting fluid rushed out through each horizontal through hole 2 can provide a tangential reaction force to the electrode body 1, and the cutting fluid flushing pressure needs to reach above 2MPa.

[0026] In summary, the working principle of this solution is as follows:

[0027] When the electrode body 1 is processed, the cutting fluid enters from the opening on the upper part of the electrode body 1 and rushes out through the horizontal through hole 2 and the vertical through hole 3 of the electrode body 1. The cutting fluid rushing out through each horizontal through hole 2 can provide a tangential reaction force to the electrode. The electrode body 1 rotates under the reaction force of the flushing fluid without the need for the drive of the spindle motor, which simplifies the structure of the arc milling machine tool and reduces the cost of the arc milling machine tool. The rotating electrode body 1 can process both the side wall and the groove.

[0028] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
