Description
Technical Field
[0001] The utility model relates to a sawtooth milling cutter, in particular to a fixed-distance saw blade milling cutter, belonging to the technical field of saw blade milling cutters. Background Art
[0002] A serrated milling cutter is a cutting tool whose blade is shaped like a saw tooth. It is usually used for high-speed rotation and cutting of part of a workpiece. A more common tooth type of serrated milling cutter in use is a fixed-pitch serrated milling cutter. The fixed-tooth serrated milling cutter has a fixed pitch and equal tooth width. It is suitable for processing metal materials such as cast iron and steel. In addition, serrated milling cutters have the advantages of high cutting efficiency, good cutting quality, and long service life. Compared with traditional flat blades, they are more suitable for cutting objects with irregular shapes and can better meet the needs of some customers.
[0003] In the prior art, a saw blade milling cutter that can be used for micro-groove processing is disclosed in announcement number CN220073374U, which includes a milling cutter disc, mounting holes and cutter teeth. The milling cutter disc, mounting holes and cutter teeth are an integrated structure. By having multiple teeth participating in milling at the same time, it can reduce tool wear and improve milling efficiency.
[0004] However, in actual use, during the use of the above-mentioned saw blade milling cutter for micro-groove processing, the milling cutter disc, mounting holes and teeth are an integrated structure. During the use of the saw blade milling cutter, the outer teeth will continue to wear, but the wear of the inner milling cutter disc will be relatively small. When the teeth are worn to a certain extent, they need to be replaced. However, the integrated structure will also replace the milling cutter disc with less wear when replacing the teeth, which is a waste of materials. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1
[0023] like Figures 1 to 4 As shown, a fixed-distance saw blade milling cutter includes a fixed-distance saw tooth 1, a connecting ring 2 fixedly mounted on the inner side of the fixed-distance saw tooth 1, and a connecting component 3 inside the connecting ring 2. The connecting ring 2 is located at the connecting component 3 and has a mounting opening 4 that matches the connecting component 3. The mounting opening 4 is opened on the connecting ring 2;
[0024] The connecting assembly 3 includes an annular mounting block 301, which is inserted into the interior of the mounting port 4, and a threaded connecting block 302 is fixedly installed in the middle of the annular mounting block 301, and a fixed ring piece 303 is threadedly connected to the bottom of the threaded connecting block 302. The outer side of the threaded connecting block 302 is connected to the inner side of the mounting port 4, and the threaded connecting block 302 and the mounting port 4 are threadedly connected. By placing the annular mounting block 301 inside the mounting port 4 and threading the fixed ring piece 303 on the other side of the annular mounting block 301, the annular mounting block 301 is fixed. The annular mounting block 301 and the fixed ring piece 303 constitute a complete cutter disc structure, thereby fixing the connecting ring 2 and the distance saw teeth 1 outside the connecting ring 2, so that after the distance saw teeth 1 are worn and replaced, the annular mounting block 301 and the fixed ring piece 303 can be recycled to reduce material waste. The threaded connection block 302 and the annular mounting block 301 are fixedly provided with a plug-in interface 5 in the middle. The distance saw teeth 1 and the connecting ring 2 are both made of tungsten steel, and the tooth structures of the distance saw teeth 1 are inclined in the same direction, and the tooth tips of the distance saw teeth 1 are trapezoidal structures. Example 2
[0025] In addition to all the technical features of the first embodiment, this embodiment also includes:
[0026] The surface of the annular mounting block 301 is provided with multiple groups of bolt openings 6, and the connection between the fixed ring piece 303 and the bolt openings 6 is provided with connecting openings matching the bolt openings 6. The internal threads of the bolt openings 6 are installed with screw rods 7. The openings of the bolt openings 6 and the connecting openings make it easy to pass the screw rods 7 through the annular mounting block 301 and the fixed ring piece 303, thereby strengthening the connection between the annular mounting block 301 and the fixed ring piece 303 and preventing the two from detaching during rotation.
[0027] The surface of the fixed-distance sawtooth 1 is coated with a heat-insulating layer 8, the outer side of the heat-insulating layer 8 is coated with a wear-resistant layer 9, and the outer side of the wear-resistant layer 9 is coated with an anti-sticking layer 10. The heat-insulating layer 8, the wear-resistant layer 9 and the anti-sticking layer 10 can increase the service life of the fixed-distance sawtooth 1.
[0028] The heat-insulating layer 8 is a metal heat-insulating coating, which is mainly composed of aluminum foil, silver and other gold-plated materials. The wear-resistant layer 9 is a ceramic wear-resistant coating. The metal heat-insulating coating can effectively reduce the temperature of the fixed-distance saw tooth 1 during processing through aluminum foil, silver and other gold-plated materials. The ceramic wear-resistant coating of the wear-resistant layer 9 has ultra-high density and ultra-strong hardness due to its unique material polymerization principle and ceramic composite function, so it has super wear resistance, which can increase the wear resistance of the fixed-distance saw tooth 1 during use.
[0029] The anti-sticking layer 10 is a polytetrafluoroethylene coating. The polytetrafluoroethylene coating has high sliding properties, reduces friction and wear, and has excellent anti-stick properties. It prevents the adhesion of glue, grease and other substances. At the same time, it has a certain high temperature resistance and can maintain stable performance within a certain temperature range.
[0030] Working principle: First, insert the annular mounting block 301 into the mounting port 4 of the connecting ring 2, then install the fixing ring piece 303 on the mounting port 4 on the other side of the connecting ring 2 through the threaded connecting block 302 on the annular mounting block 301, so that a cutter head for fixing the connecting ring 2 and the fixed-distance sawtooth 1 can be formed through the annular mounting block 301 and the fixing ring piece 303, then install multiple sets of screws 7 on the bolt ports 6, and install the screws 7 through the bolt ports 6 to the connecting port of the fixing ring piece 303, so that the two are connected. The connection is tighter to avoid the two falling off during the processing of the fixed-distance saw tooth 1, and then the fixing component can be installed at the plug-in interface 5 to fix the overall structure for use. During use, the anti-sticking layer 10 coated on the surface of the fixed-distance saw tooth 1 can reduce the adhesion of processing waste to the outside of the fixed-distance saw tooth 1, thereby increasing the precision of the fixed-distance saw tooth 1 in processing and the generation of heat, while the wear-resistant layer 9 and the heat-insulating layer 8 on the inside can increase the wear resistance and heat-insulating effect of the fixed-distance saw tooth 1 during use, thereby increasing the service life of the fixed-distance saw tooth 1.
