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

[0041] 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 acco...

Embodiment 2

[0066] The processing method of a mechanical quick-change aluminum ingot double-milling combined tool holder of this embodiment is basically the same as that of embodiment 1, the difference is that: this embodiment designs the installation slope 13 of the cutter head relative to the tool holder plane 12. The inclination angle β is 50°, and 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 8...

Abstract

The invention discloses a machining method of a mechanical quick-changing aluminum ingot dual-milling combined tool apron and belongs to the technical field of metal cutting. The machining method comprises the steps of 1, tool apron raw materials preparation, 2, annealing treatment, namely increasing the temperature to the range of 740-760 DEG C, preserving heat for 4-6 hours, cooling at a rate within the range of 5-10 DEG / h, cooling until the temperature is below 600 DEG C, and then discharging for cooling in air, 3, rough machining of forging blank, 4, thermal treatment, namely heating to the quenching temperature range of 840-860 DEG C in 20-25 minutes, and tempering by oil cooling within a tempering temperature range of 650-660 DEG C, and 5, deep processing, tilting a fine-milling tool bit mounting inclined surface at the angle of 51 degrees relatively to the plane of the tool apron and a fine milling escape surface gamma at the angle of 9 degrees relatively to the horizontal plane. According to the machining method of the mechanical quick-changing aluminum ingot dual-milling combined tool apron, the machining method of the dual-milling combined cutting tool is improved and quick cutting to the metal aluminum ingot is finished by increasing the tilt angle of the tool bit, and therefore, the tool bit and the tool apron of the cutting tool are enabled to have good toughness, wear resistance and tensile strength, and the service life of the cutting tool is prolonged.
