Problems solved by technology

[0003] Ultrasonic cutters are made of titanium alloy with high hardness. Traditional ultrasonic cutters are manufactured by machining, which has a large amount of wear on the cutters, long working hours, high cost, and surface defects are prone to occur during machining, which reduces the service life of the cutters.
[0004] A set of ultrasonic cutters is expensive, and a single ultrasonic cutter costs tens of thousands. In daily use, it is inevitable that there will be small bumps, and even a very small amount of impurities in the rubber will cause the ultrasonic cutter to fail during work. The broken knife is scrapped, and the broken knife can only be discarded, resulting in a great waste of resources. At present, there is no way to repair the ultrasonic knife on the market.

Embodiment 1

[0055] as attached Figure 1-3 Shown, the ultrasonic cutter of this embodiment includes:

[0056] Knife holder 10, comprises the cutter holder body 11 of cuboid, and the two end surfaces perpendicular to its length direction on the cutter holder body 11 are respectively extended with protrusions 12, and the width of protrusions 12 gradually decreases along the direction away from said knife holder body. Small, screw holes 13 are set at the bottom of the knife seat 10;

[0057] The knife body 20 is arranged above the knife seat 10 and includes a concave arc-shaped transition area 21 close to the knife seat 10 and a middle part 22 above the arc-shaped transition area. Two vertical strips are symmetrically arranged on the knife body 20. Through hole 23;

[0058] The cutting portion 30 is located above the knife body 20 , and the blade thickness D of the cutting portion 30 is 0.3mm. In other embodiments, the cutting portion 30 can be any value of 0.2-0.4mm.

[0059] In this emb...

Embodiment 2

[0063] The present invention also provides the 3D printing preparation method of the ultrasonic cutter of the above-mentioned embodiment 1, comprising the following steps:

[0064] S1. Raw material treatment: Carry out vacuum drying treatment on spherical TC4 particles, and cover with a protective film that can prevent impurities in the air from falling after the treatment. In this embodiment, fresh-keeping film is used; and it is found through experiments that TC4 raw material particles must be fresh and placed for 3 Ultrasonic cutters printed by TC4 powder for more than one month cannot be used;

[0065] In this embodiment, TC4 particles with a particle size of 17-20 μm are selected to prevent the internal structure from being affected by too large a span when the particles are sintered, so that they cannot be used; use a thickness of 20 layers to ensure that the printed stack is as small as possible;

[0066] S2. 3D printer preparation: clean the inner cavity of the 3D prin...

Embodiment 3

[0077] The 3D printing preparation method of ultrasonic cutter comprises the following steps:

[0078] S1. Raw material processing: the spherical TC4 particles are vacuum-dried, and covered with a protective film that can prevent impurities in the air from falling into them after processing. In this embodiment, preservative film is selected; TC4 raw material particles must be fresh;

[0079] In this embodiment, TC4 particles with a particle size of 20-30 μm are selected to prevent the internal structure from being too large to be affected when the particles are sintered, so that they cannot be used; use a thickness of 30 layers to ensure that the printed stack is as small as possible;

[0080] S2. 3D printer preparation: clean the inner cavity of the 3D printer so that the molding cavity and powder cavity do not contain dust, floating objects and other impurities. pipeline with filter;

[0081] And every time the 3D printer prints, it needs to replace with a new scraper to pr...

Abstract

The invention relates to the technical field of ultrasonic cutting tools, in particular to an ultrasonic cut-off knife and a 3D printing preparation method and repairing method thereof.The ultrasonic cut-off knife comprises a knife holder comprising a knife holder body, and the two end faces, perpendicular to the length direction, of the knife holder body extend outwards to form protruding parts correspondingly; the width of the protruding part is gradually reduced in the direction away from the tool apron body. The cutter body comprises a concave arc-shaped transition area close to the cutter holder and a middle part located above the arc-shaped transition area, and two vertical strip-shaped through holes are symmetrically formed in the cutter body; the ultrasonic cut-off knife is reasonable in structural design, the problems that the ultrasonic cut-off knife is prone to cracking and notches are prone to being generated in the cutting use process are greatly solved, the quality of the cut-off knife is improved, and the service life of the cut-off knife is prolonged; a traditional machining mode is broken through, the ultrasonic cutter is manufactured through the 3D printer technology, and the ultrasonic cutter is normally used on a forming machine. The ultrasonic cutter is repaired through a 3D printing grafting technology preferentially, and waste is turned into wealth.

Description

technical field [0001] The invention relates to the technical field of ultrasonic cutting tools, in particular to an ultrasonic cutting tool and its 3D printing preparation method and repair method. Background technique [0002] In rubber tire processing, rubber material cutting according to lamination process and production specifications is an essential process. The existing more advanced cutting technology is to use ultrasonic cutter to vibrate and break the molecular chain of rubber material by ultrasonic high-frequency oscillation. [0003] Ultrasonic cutters are titanium alloys with high hardness. Traditional ultrasonic cutters are manufactured by machining, which has a large amount of wear on the cutters, long working hours, and high costs. In addition, surface defects are prone to occur during machining, which reduces the service life of the cutters. [0004] A set of ultrasonic cutters is expensive, and a single ultrasonic cutter costs tens of thousands. In daily u...
