Description
Technical Field
The invention relates to an alloy turning blade, in particular to a microstructure hard alloy turning blade for cutting AISI 201.
Background
Cutting machining is the most main product machining means in the manufacturing industry, and along with continuous progress of cutting technology, in product machining such as AISI201 alloy material, the cutting machining precision is gradually higher and higher, the quality of machined products and service life are continuously improved, and even the phenomenon that grinding is replaced by cutting occurs. In cutting, the cutting edge is the main part for removing material, and the working environment of the cutting edge and the rake face area near the cutting edge is the most severe, and the temperature of the tool is rapidly increased mainly in cutting, which not only reduces the durability of the tool, but also reduces the quality of cutting.
The structure of the blade is directly related to the durability of the cutter, the processing efficiency and the processing quality, so that reasonable cutting edge and the design of the cutting edge near-field structure are particularly important to improving the performance of the turning tool.
Similar patents filed by this group, such as a micro-structured cemented carbide turning insert (CN 106493396B) for cutting 304 stainless steel, disclose an alloy insert that has the effect of reducing cutting temperature and improving insert durability by providing a stick-ball-shaped micro-groove near the cutting edge of the insert.
Although the present team achieves the aims of reducing cutting temperature and improving durability by designing the micro-groove with a shape like a stick and the like in the near-cutting edge area, the prior micro-groove structural design still has the defects. The main point is that the micro-groove structure is critical to the distribution of the temperature field near the cutting edge, and the distribution of the temperature field is a key factor affecting the local temperature rise and the service life of the cutting edge, so that the effect of different micro-groove structures on the reduction of the cutting temperature of the cutting edge and the extension of the service life is different, and how to design a micro-groove structure capable of further reducing the cutting temperature and prolonging the service life is necessary.
Disclosure of Invention
The invention aims to provide a microstructure cemented carbide turning insert for cutting AISI 201. The invention has the characteristics of better cutting temperature reduction effect in the near-field of the cutting edge, higher durability of the blade and longer service life.
The technical scheme of the invention is as follows: a microstructure hard alloy turning blade for cutting AISI201 comprises a rake face, wherein the sharp angle of the rake face is a cutting edge, one side of the cutting edge is a main cutting edge, the other side of the cutting edge is a minor cutting edge, and the inner side of the cutting edge is a cutting edge near region; the cutting edge is provided with micro grooves at the near region, and the micro grooves are in an asymmetric shoe-shaped structure with unequal widths and unequal depths.
In the microstructure hard alloy turning blade for cutting AISI201, the section of the micro groove on the front cutter surface is of an asymmetric curve type, and the bottom surface of the micro groove is of a smooth transition curve surface; the maximum depth of the micro groove is 0.25-0.50 mm; the distance between the edge of the micro groove and the edge of the main cutting edge is 0.1-0.18 mm; the length of the micro groove on the side close to the main cutting edge is 2.5-3.7 mm, and the length of the micro groove on the side close to the auxiliary cutting edge is 2.0-2.8 mm; the maximum width of the micro-groove is 0.8-1.2 mm.
The micro-structure hard alloy turning blade for cutting AISI201 has the maximum depth of 0.35mm; the distance between the edge of the micro groove and the edge of the main cutting edge is 0.15mm; the length of the micro groove on the side close to the main cutting edge is 3.5mm, and the length of the micro groove on the side close to the auxiliary cutting edge is 2.5mm; the maximum width of the micro-groove is 1mm.
The microstructure cemented carbide turning blade for cutting AISI201 is characterized in that the connection form of the outer edge of the micro groove and the main cutting edge is equal-height type and unequal-height type.
The microstructure hard alloy turning blade for cutting AISI201 is observed along the direction vertical to the main rear cutter surface, and the main cutting edge is in a linear or arc shape.
The beneficial effects of the invention are that
Compared with the prior art, the invention has the advantages that the gold ingot type micro-groove structure is arranged at the near region of the cutting edge of the front cutter surface, so that the actual contact area of the cutter and the scraps is reduced when the cutter cuts the high-temperature alloy AISI201, and the cutting temperature is reduced, thereby effectively improving the durability of the cutter. In the cutting process of the cutter, the cutter-chip contact area can generate severe friction and deformation, local high temperature and high pressure are generated, a large amount of cutting heat is generated, meanwhile, shearing sliding occurs in the first deformation area in the cutting process, the shearing deformation resistance of the shearing area is almost completely converted into the cutting heat, and the cutting temperature of the cutter can be increased through heat transfer. According to the invention, through a great amount of experimental analysis on the cutting AISI201, the applicant finds that when a 'shoe-shaped gold ingot' micro groove structure is arranged on a rake face at a distance of 0.1-0.18 mm (optimally 0.15 mm) from a main cutting edge, the maximum depth of the micro groove is between 0.25-0.50 mm, the lengths of the micro groove, which is close to the main cutting edge and a minor cutting edge, are respectively 2.5-3.7 mm and 2.0-2.8 mm, and the maximum width is 0.8-1.2 mm, the new structure of the near domain of the cutting edge has a relatively obvious cooling effect; mainly because: 1) The existence of the micro grooves increases the contact area of the cutting chip and the front cutter surface of the cutter, reduces the normal stress of the cutter at the cutter-chip contact position, gradually reduces the normal stress to a certain critical value, reduces the possibility of internal friction in the metal of the bottom layer of the cutting chip, and converts the internal friction area of the original cutter-chip contact area into an external friction area, namely a bonding friction area into a sliding friction area, and reduces the temperature of the cutter due to the fact that the internal friction area is a main source area of heat of the cutter; 2) The existence of the micro grooves changes the thermal coupling effect of the cutting process of the cutter, changes the stress strain state of the first deformation zone, improves the shearing slip of the first deformation zone, and reduces the generation of cutting heat. The comprehensive effect effectively reduces the cutting temperature of the cutter, thereby effectively ensuring the durability of the turning cutter and prolonging the service life.
When the cutting tool is used, the micro groove has the function of breaking chips, the chips flow along the surface of the micro groove in the cutting process, the curved surface has a certain blocking effect on the flow of the chips so as to curl the chips, when the chips flow through the outer edge of the micro groove, the chips are subjected to the high stress action at the place, and when the strain of the chips due to the local stress action reaches the limit strain value, the chips are broken. Compared with the common chip breaker and antifriction groove, the micro groove is different in that except for the design principle, the micro groove is mainly positioned in a cutter-chip contact area near the cutting edge of the front cutter surface, is generally smaller than the chip breaker and antifriction groove in scale, and is positioned in a range relatively far away from the main cutting edge; in the cutting process, the contact between the micro-groove cutter and the bottom layer of the cutting chip is in a semi-contact state, so that the contact between the micro-groove cutter and the cutter in the flowing process of the cutting chip is further reduced.
In order to better prove the beneficial effects of the invention, the applicant makes the following simulation experiments: the cutting AISI201 simulation comparison was performed using a common cemented carbide turning tool (hereinafter referred to as a comparison turning tool) with the present invention.
The above comparative turning tool and each comparative experiment set of the present invention were performed under the same cutting conditions (cutting amount, tool geometry, tool and workpiece material, etc.), and the simulation comparative experiment scheme and results of the cutting AISI201 are shown in table 1.

As shown in Table 1, the invention can effectively reduce the highest temperature of the cutter, the temperature reduction range reaches 21.62-26.96%, and the temperature reduction effect is obvious.

from the above cutting simulation process, it can be derived that when h=0.35 mm, l 1 ＝3.5mm，L 2 The main dimensions of the micro pits were determined by the values of =2.5 mm, w=1.0 mm, cutting force and cutting temperature being the smallest.

And when the time is 12min, the pit abrasion area of the original cutter is increased, and the micro-pit cutter is only at the bottom of the pit, so that abrasive abrasion is generated, and the color is lightened. When the original cutter is cut for 16min, pit abrasion of the front cutter surface is very serious, the sliding line of the front cutter surface is very clear, and at the same time, the front cutter surface abrasion of the micro-pit turning tool is very slight, and the pit abrasion is basically not displayed. The micro-pit tool can continue cutting until the cutting time is 82min because the abrasion width of the rear tool face does not reach the specified value, and at this time, the front tool face only generates micro-pits at the position of the auxiliary cutting edge.
Fig. 15 is a graph showing the comparison of the flank face of a primary cutter with the inventive cutter when the cutting amount vc=120 m/min, f=0.15 mm, ap=1.5 mm, and the wear width of the flank face of the cutter reaches 0.15mm as a standard; as can be seen from fig. 15, the wear width of the rear tool face of the micro-pit turning tool is 0-8min in the cutting front section and is slightly smaller than that of the original turning tool. When the cutting time is 12-16min, the abrasion width of the rear cutter surface of the micro-pit turning tool is greatly smaller than that of the original turning tool, when the cutting time is more than 16min, the abrasion width of the micro-pit turning tool is slowly increased, until the cutting time reaches 64min, the cutting width is increased to 142 mu m, and when the cutting time reaches 82min, the abrasion width of the cutter reaches 150 mu m. The service life of the micro-pit turning tool is prolonged by more than 5 times.

as can be seen from fig. 16 and 17, the baseball-shaped dimple cutter was cut for 36 minutes in total. And 4min, the baseball-shaped micro-pit cutter has obvious material peeling at the pit position of the front cutter surface, the abrasion of the rear cutter surface is slight, and the abrasion width reaches 50 mu m. At this time, the front and rear surfaces of the baseball-shaped dimple cutter were hardly changed, and the wear width was 25 μm.8min later, the main cutting edge of the baseball-shaped micro-pit cutter is at a certain position, and micro damage occurs. The rear cutter surface has obvious bonding phenomenon, the abrasion width reaches 68 mu m, the change of the front cutter surface of the gold ingot-shaped micro-pit cutter is very small, only the color of the pit edge becomes shallow due to the sliding friction of chips, the change of the rear cutter surface is very small, and the abrasion width reaches 35 mu m. When the time is 12min, the abrasion of the main cutting edge of the baseball-shaped micro-pit cutter is very obvious, the damaged position is deepened, a groove appears, the auxiliary cutting edge can see obvious abrasion marks, the abrasion width of the rear cutter surface is continuously changed, and the abrasion width reaches 95 mu m. At this time, the gold ingot type cutter only has the color brightening inside the pit, the other main cutting edge and the auxiliary cutting edge are not changed, the rear cutter surface is not obviously changed, and the abrasion width reaches 52 mu m. When the cutting time reaches 36min, the damaged position of the main cutting edge of the baseball-shaped micro-pit cutter is deepened continuously, the area is increased in an emission shape, the bonding phenomenon is very serious, the deformation of the auxiliary cutting edge is serious, and a very obvious dent appears. The abrasion of the rear cutter surface is very serious, the bonding phenomenon is abnormal, the abrasion width reaches 150 mu m, the specified value is reached, and the cutting experiment is finished. At the moment, the gold ingot-shaped micro-pit cutter only has the color of the surface of the cutting edge to lighten, only has tiny abrasion, and the abrasion width of the rear cutter surface is 60 mu m. When the cutting time reaches 82min, the shoe-shaped gold ingot shaped micro-pit cutter has no obvious change of the front cutter surface, and only the abrasion width of the rear cutter surface reaches a specified value. By comparison, compared with a baseball-shaped micro-pit cutter, the gold ingot-shaped micro-pit cutter cuts the same material, and the service life is prolonged by more than 2 times.
