[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A screw rolling machine blade comprises a blade body, wherein the blade body adopts an equilateral triangle structure, the three corners of the blade body are cutting blades, the three sides of the blade body are arranged with outward arc protrusions, and a mounting hole is arranged at the center of the blade body.

[0007] Preferably, a cutter head is provided on the outside of the blade body, a mounting groove for inserting the blade body is opened on the surface of the cutter head, a mounting screw threadedly connected to the mounting groove is inserted into the inside of the mounting hole, and a cutter rod is fixedly provided on the side wall of the cutter head.

[0008] Preferably, the mounting groove is in the shape of an equilateral triangle, and one side of the mounting groove passes through the side wall of the cutter head, and a cutting edge of the blade body extends to the outside of the cutter head.

[0009] Preferably, the back side of the blade body is arranged in a plane.

[0010] Furthermore, three sides of the front surface of the blade body are provided with chip removal grooves.

[0011] Preferably, the cutting edge of the blade body has a back angle of 5°.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0013] 1. The utility model adopts an equilateral triangle structure for the blade body, and the three corners of the blade body are cutting blades, the cutting blades adopt a 5° back angle, the three sides of the blade body are arranged with outward arc protrusions, and there are three cutting blades, which not only prolongs the service life of the blade body, but also makes the cutting sharper and the cutting processing efficiency high.

[0014] 2. The utility model provides a mounting hole at the center of the blade body. After the mounting screw is inserted into the mounting hole, the blade body is pressed by the nut, so that the blade body can be firmly mounted inside the mounting groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] The utility model embodiment discloses a screw rod rolling machine blade.

[0023] The utility model provides Figure 1The screw rolling machine blade shown includes a blade body 1. The blade body 1 adopts an equilateral triangle structure. The three corners of the blade body 1 are cutting blades. The cutting blade of the blade body 1 adopts a back angle of 5°. The three sides of the blade body 1 are arranged with outward arc protrusions. There are three cutting blades, which not only extend the service life of the blade body 1, but also make the cutting sharper and the cutting processing efficiency high. A mounting hole 2 is provided at the center of the blade body 1, and chip discharge grooves 6 are provided on the three front sides of the blade body 1, which can ensure that the debris of the blade body 1 is discharged to both sides during the cutting process.

[0024] Finally, in order to be able to firmly install the blade body 1, as Figure 2-3 As shown, a cutter head 3 is provided on the outside of the blade body 1, and a mounting groove 4 for placing the blade body 1 is opened on the surface of the cutter head 3. The back side of the blade body 1 is set in a flat surface so that the back side of the blade body 1 is fitted with the bottom of the mounting groove 4, and a mounting screw 5 threadedly connected to the mounting groove 4 is inserted into the inside of the mounting hole 2. After the mounting screw 5 is inserted into the inside of the mounting hole 2, the blade body 1 is pressed by a nut so that the blade body 1 can be firmly installed in the inside of the mounting groove 4; a cutter rod 7 is fixedly provided on the side wall of the cutter head 3, and the mounting groove 4 is set in an equilateral triangle groove, and one side of the mounting groove 4 passes through the side wall of the cutter head 3, a cutting edge of the blade body 1 extends to the outside of the cutter head 3, and a cutting edge extending from the blade body 1 is the cutting part. When one of the cutting edges is worn out, the other two cutting edges can be switched for use.

[0025] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
