Problems solved by technology

In the prior art, aluminum ingots are usually cut by double-milling combination cutters, but the traditional double-milling combination cutters for aluminum ingots have the following two problems: first, the toughness and wear resistance of the cutters are poor, and the process of cutting aluminum ingots In the middle, high heat will be generated due to friction, and the tensile strength of the tool head and tool seat is also poor. Often, the tool head will be pulled or the cutting edge will be cracked during the cutting process, resulting in a short service life of the tool; secondly, due to The overall mass of the tool after welding is relatively large. After the cutting edge of the cutting edge is cracked, when the cutting edge is sharpened and repaired, the impact force of the cutting edge on the grinding wheel is relatively large, which is prone to danger and the operation of edge grinding is not easy to control. The above defects are seriously limited. The application of double milling combination cutter
This application uses fasteners to detachably fix the cutting insert on the cutting tool, but the application has a complex structure and is inconvenient to install and disassemble the insert

Embodiment 1

[0047] see image 3, a mechanical quick-change aluminum ingot double-milling combination cutter in this embodiment is mainly used for cutting metal aluminum ingots. The double-milling combination cutter includes 2 symmetrically arranged milling cutters. The shape and structure of the 2 milling cutters are similar. It mainly includes a cutter seat 1, a cutter head 2 and a quick change structure of the cutter head. see figure 2 In the present embodiment, the inclination angle β of the cutter head installation slope 13 of the cutter holder 1 relative to the cutter holder plane 12 is 51° (that is, the angle between the cutter head installation slope 13 and the cutter holder plane 12 is 51°). This inclination design is an innovation of the present embodiment. The inventor pointed out that at the beginning of the design of the tool seat 1 of the double milling combination cutter, it designed the inclination angle of the cutter head installation inclined surface 13 as follows accor...

Embodiment 2

[0072] A mechanical quick-change aluminum ingot double-milling combined cutter in this embodiment is basically the same as in Embodiment 1, except that the inclination β of the cutter head installation slope 13 relative to the tool seat plane 12 is designed to be 50° in this embodiment. °, the arc surface radius of the arc groove 11 is 15mm. In the tool seat processing technology of this embodiment: the components of the forged blank in step 1 are calculated by weight percentage: C: 0.44, Si: 0.37, Mn: 0.80, S: 0.035, P: 0.035, Cr: 1.1, Ni: 0.030 , Cu: 0.030, the rest is Fe. The annealing process of step 2 is as follows: first, the temperature is raised to 760°C, held for 6 hours, then cooled at a rate of 5°C / h, the temperature is lowered to below 600°C, and the furnace is air-cooled. After annealing, the hardness of the forged blank is 163HBS. The heat treatment process of step 4 is: heating to the quenching temperature of 860°C within 25 minutes, oil cooling; then tempering...

Embodiment 3

[0074] A mechanical quick-change aluminum ingot double-milling combination cutter in this embodiment is basically the same as in Embodiment 1, except that the inclination β of the cutter head installation slope 13 relative to the tool seat plane 12 is designed to be 55° in this embodiment. °, the arc surface radius of the arc groove 11 is 13mm. In the tool seat processing technology of this embodiment: the components of the forged blank in step 1 are calculated by weight percentage: C: 0.37, Si: 0.17, Mn: 0.50, S: 0.032, P: 0.034, Cr: 0.80, Ni: 0.028 , Cu: 0.030, the rest is Fe. The annealing process of step 2 is as follows: firstly, the temperature is raised to 740°C, held for 4 hours, then cooled at a rate of 7°C / h, the temperature is lowered to below 600°C, and the furnace is air-cooled. After annealing, the hardness of the forged blank is 160HBS. The heat treatment process of step 4 is: heating to the quenching temperature of 840°C within 25 minutes, oil cooling; then tem...

Abstract

The invention discloses a quick-replaceable mechanical aluminium ingot double-milling combined knife, belongs to the technical field of metal cutting. The combined knife comprises a knife holder, a knife head and a knife head quick-replacing structure, wherein the inclination beta of the mounting inclined plane of the knife head of the knife holder relative to the knife holder plane is 50-55 degrees; a transitional arc-shaped groove is formed between the knife holder plane and the knife head mounting inclined plane; a knife head mounting groove is formed in the upper part of the mounting inclined plane of the knife head; the knife head is inserted into the knife head mounting groove and is fixed by the knife head quick-replacing structure; the knife head adopts a parallel hexahedron structure and comprises cutting edges which are arranged in a diagonal manner. The quick-replaceable mechanical aluminium ingot double-milling combined knife can finish quick cutting metal aluminium ingots by adopting the enlarged knife head cutting inclination, multiple knife edges in a single knife and quick replacement, and meanwhile, the processing method of the double milling combined knife is further improved, so that the knife head and the knife holder of the knife are both good in toughness, abrasive resistance and tensile strength, and the service life of the knife is prolonged.

Description

technical field [0001] The invention relates to the technical field of metal cutting, and more specifically relates to a mechanical quick-change aluminum ingot double-milling combination cutter. Background technique [0002] Aluminum is a non-ferrous metal that is second only to steel in terms of output and consumption in the world. It is widely used in industry. When aluminum is used as a raw material in daily industry, it is usually called aluminum ingot. In the prior art, aluminum ingots are usually cut by double-milling combination cutters, but the traditional double-milling combination cutters for aluminum ingots have the following two problems: first, the toughness and wear resistance of the cutters are poor, and the process of cutting aluminum ingots In the middle, high heat will be generated due to friction, and the tensile strength of the tool head and tool seat is also poor. Often, the tool head will be pulled or the cutting edge will be cracked during the cutting ...
