Description
Technical Field
The invention relates to the field of metal cutting machining, in particular to a milling blade with a chip control function.
Background
Turning and milling are two common machining modes in the field of metal cutting machining at present. In view of the characteristics of the tool, the turning process is usually continuous, whereas the milling process is usually intermittent, since a plurality of cutting units are distributed on the milling tool, and each cutting unit is repeatedly involved in cutting the part in the actual process. Because the milling cutter cuts continuously in the processing, the iron filings processed are naturally not too long, and the iron filings processed are forced to separate and break under the action of centrifugal force due to the centrifugal force generated by the high-speed rotation of the milling cutter, the structural design in the aspect of chip control is not excessively considered in the structural design of the milling cutter based on the cutting principle.
For example, the data published in international patent WO2015/115379 shows that the structural design of the blade can fully ensure the strength of the tip and reduce the cutting resistance, thereby prolonging the service life of the cutter, however, the upper top surface of the blade has no control structure for scrap iron, the influence of the scrap iron on the main cutting edge is ignored, and the blade of the type has certain defects. Through a plurality of practical verifications, when soft material parts are machined, particularly when machining parameters with larger cutting depth are used, the machined scrap iron can naturally curl along the front cutter surface of the blade without any external intervention, and continuously curl and extend upwards perpendicular to the surface of the machined part. The iron filings can have great probability of continuously rubbing against the unused front cutter surface in the curling growth process, and the surface protective coating of the blade can be damaged or peeled off along with the aggravation of friction force and friction heat; secondly, the scrap iron can have great probability of continuously contacting and colliding with the unused main cutting edge in the process of curling and growing, and as the cutting process is carried out, the contact and the collision can finally lead the main cutting edge to generate tiny gaps, and the continuous expansion is possible, and the adverse effects can lead the unused blade structural part to be damaged without any reason or to be in danger of damage, thereby leading the blade to fail in advance, and the service life to be seriously influenced

Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
The present invention is directed to the problem of the prior art by referring to fig. 1-7, and provides a milling insert with chip control, comprising an insert body 1 and an insert body 40, wherein the insert body 1 comprises an insert body 1, which is approximately cuboid, surrounded by an upper top surface 2, a lower bottom surface 3 and end surfaces 5 and side surfaces 4 connected to said upper top surface 2, said lower bottom surface 3, the insert body 1 being provided with a central hole 6 at its axisymmetric centre O. The cutter body 40 includes a cutter pocket 28 for mounting the cutter body 1. The preparation of the blade main body 1 belongs to one-time compression molding of a precision die, and then the blade main body is formed by sintering and shrinking in a vacuum high-temperature sintering furnace, and finally a physical finished product is formed through subsequent treatment.
The upper top surface 2 is mainly a surface that participates in actual cutting. The upper top surface 2 and the side surface 4 extend according to respective curvatures to form main cutting edges 8, 8', the upper top surface 2 and the end surface 5 extend according to respective curvatures to form secondary cutting edges 7, 7' and transition edges 9, 9', the main cutting edges 7, 8' and the secondary cutting edges 7, 7 'are smoothly connected by convex curves to form main cutting angles 10, 10', the main cutting edges 8, 8 'and the transition edges 9, 9' are smoothly connected by convex curves to form secondary cutting angles 11, 11', and the secondary cutting edges 7, 7' and the transition edges 9, 9 'are smoothly connected by concave curves to form clearance grooves 12, 12'.
In fig. 1,2,3 and 4, the plane of the secondary cutting edge 7, 7' is parallel to the lower bottom surface 3, the clearance grooves 12, 12' and the secondary cutting edge 7, 7' are in the same plane, and the transition edge 9, 9' is close to one side of the secondary cutting corner 11, 11' in the direction. In view 2, the minor cutting edges 7, 7 'are at an angle of approximately 90 degrees to the major cutting edges 8, 8'. The secondary cutting edges 7, 7' have a relatively low probability of machining breakage and do not directly participate in the removal of the large margin, but rather a finishing treatment of the machined surface for improving the quality of the machined surface. The main cutting edge 8, 8 'is formed by five spatial sub-curves joined end to end smoothly, in fig. 5 the main cutting edge 8, 8' comprises a first sub-curve 81, a third sub-curve 83 and a fifth sub-curve 85 having distinct straight-line segment characteristics, and the third sub-curve 83 has distinct characteristics of being inclined from the main cutting corner 10, 10 'to the auxiliary cutting corner 11, 11'. The first and fifth sub-curves 81, 85 are substantially parallel to the lower bottom surface 3. A second sub-curve 82 is formed by the first sub-curve 81 and the third sub-curve 83 which are in smooth contact with each other from the beginning to the end through a convex curve section, and a fourth sub-curve 84 is formed by the third sub-curve 83 and the fifth sub-curve 85 which are in smooth contact with each other from the beginning to the end through a concave curve section; the vertical height H of the first sub-curve 81 relative to the lower floor 3 is significantly greater than the vertical height H of the fifth sub-curve 85 relative to the lower floor 3, preferably h=3.5 mm, h=2.5 mm. The main cutting edges 8 and 8' are important participation structures for removing the allowance of metal parts in cutting processing, and directly influence the cutting effect and the service life of the blade, so that the abrasion probability of the main cutting edges 8 and 8' is reduced, the collision risk of the main cutting edges 8 and 8' and external factors is reduced, the life cycle of the blade main body 1 can be improved, and meanwhile, the inclination angle formed by the third sub-curve 83 and the lower bottom surface 3 is smaller than 90 degrees, and the inclination structure is more favorable for discharging scrap iron and can prevent the scrap iron from scratching the processed surface.
The upper top surface 2 is a core layer for controlling the flow direction and curling of the iron filings. Chip control grooves 30, 30 'are arranged on the upper top surface 2 near the secondary cutting edges 7, 7', the main cutting edges 8, 8', and the chip control grooves 30, 30' are approximately concave on the upper top surface 2 and are in smooth contact with the upper top surface 2. The secondary cutting edge 7, 7', the primary cutting edge 8, 8', the primary cutting corner 10, 10' together with the chip-controlling flute 30, 30' form a complete cutting control system 13, 13'. The chip control flutes 30, 30 'are mainly formed by the main lands 20, 20', the rake surfaces 21, 21 'and the chipbreakers 22, 22'. The main edge strips 20, 20 'are formed by extending the main edge strips 8, 8' inwards, that is, the main edge strips 8, 8 'move a certain distance to the central hole 6 along the direction parallel to the lower bottom surface 3, the width values of the main edge strips 20, 20' are constant, the width preferred value is 0.12mm, and the main edge strips 8, 8 'and the main edge strips 20, 20' are simultaneously responsible for enabling the blade main body 1 to smoothly cut into and cut out parts with smaller cutting resistance, thus completing one-time cutting task, inhibiting cutting vibration, reducing cutting vibration marks and improving surface processing quality. In fig. 3, the angle a formed by the rake surfaces 21, 21' and the lower bottom surface 3 is indicated by an auxiliary line W, which is parallel to the lower bottom surface 3, preferably 15 ° < a < 25 °. When the blade body 1 is mounted on the blade body 40, the blade front blade faces 21, 21 'and the lower bottom surface 3 have to be adjusted within the range according to the actual situation, rather than a fixed value, due to the axial and radial mounting angles of the blade body 40, so that positive combined inclination angles of the front blade faces 21, 21' can be ensured when the blade body 40 is matched for cutting, and the cutting can be smoothly performed.
The chipbreaker 22, 22 'is adjacent to the void-avoidance groove 12, 12' at one end and the central aperture 6 at the other end. The chipbreaker 22, 22' has a length of 0.25 to 0.35 times the total length of the insert L, preferably 0.3 times, preferably l=11.75 mm. In fig. 2, the length direction of the chip breaker 22, 22' forms an angle of not more than 90 degrees, preferably 75 degrees, with the direction from the minor cutting edge 7, 7' to the major cutting corner 10, 10', and in fig. 3, the height T of the highest point of the chip breaker 22, 22' to the lower bottom surface 3 is not higher than the height T of the major cutting edge 8, 8' to the lower bottom surface 3, i.e. t.gtoreq.t. The chip breaker 22, 22' is a meandering portion, the meandering portion comprises at least a section of concave curve and a section of convex curve, the concave curve is connected with the convex curve, the concave curve is close to one side of the main edge belt 20, 20', wherein the concave curve of the chip breaker 22, 22' is lower than the upper top surface 2, the convex curve is higher than the upper top surface 2, and the meandering portion plays a role in guiding iron filings to curl. The chip breaker 22, 22' can effectively flow and curl the scrap iron according to a preset mode, reduces the contact area with the top surface 2 on the blade main body 1, and can be away from the main cutting edges 8, 8', so that the structure of an unused cutting control system 13, 13' can be protected, and the purpose of chip control of the blade main body 1 is achieved.
In the assembly mode of the present invention, as shown in fig. 6 and 7, the blade body 1 is placed in the pocket 28 in the cutter body 40, so that the first rear corner surface 41 of the blade body 1 is bonded to the first positioning base surface 31 in the pocket 28, the second rear corner surface 51 is bonded to the second positioning base surface 38 in the pocket 28, and the lower bottom surface 3 is bonded to the third positioning base surface 32 in the pocket 28. The blade body 1 is pressed into the pocket 28 in the blade body 40 by the pressure of the locking screw 33. The locking screw 33 mates with the threaded bore 29 in the pocket 28. In order to achieve stable cutting, the close fit of the insert body 1 with the insert body 40 is important, and thus, there is a positional deviation between the center hole 6 of the insert body 1 and the screw hole 29 of the insert body 40, and the insert body 1 is tightly locked in the insert pocket 28 by the locking screw 33 in an eccentric manner. In general, the cutter body 40 has at least one cutter slot 28, and when the blade body 1 is all mounted on the cutter slot 28, the cutter body 40 is mounted on a machine tool through a tool system, and a main shaft of the machine tool drives the cutter body 40 to rotate around a rotation center O' at a high speed, so that cutting is realized.
While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the present invention.
