[0032] In the related art, the existing blade particles are prone to collision during turning, resulting in damage to the machine tool and the workpiece. For example, when threading a screw, the required thread is very close to the screw head, so that during the cutting process, the blade particles are very likely to collide with the screw head, resulting in damage to the machine tool and the workpiece.
[0033] See also Figure 1 and Figure 2 , Figure 1 1 is a schematic diagram of the three-dimensional structure of the blade particle 100 provided in the embodiment of the utility model. Figure 2 yes Figure 1 The schematic diagram of the structure of the knife particle 100 in the front view direction. The embodiment of the utility model provides a knife particle 100 for thread processing, the knife particle 100 includes a main body 11 and a cutting part 12, and the main body 11 is used to connect with the tool body (not shown). The cutting part 12 is connected to the outer peripheral side of the main body 11, and the end face 120 of the cutting part 12 in the feed direction is provided with an air avoidance groove 1200, and the air avoidance groove 1200 is used to avoid the workpiece (not shown) during cutting. It should be noted that the feed direction is the direction in which the knife particle 100 is relatively close to the workpiece, that is, it can be understood as the direction in which the knife particle 100 is facing the workpiece. In some embodiments, the tool (not shown) and the workpiece are both installed on a machine tool (not shown), and the workpiece rotates around its own axis under the drive of the spindle, and the knife particle 100 moves close to the workpiece along the axial direction of the workpiece under the drive of the motion mechanism, and the movement trajectory of the knife particle 100 forms the thread surface of the workpiece. The outer peripheral side of the main body 11 refers to the side of the main body 11 perpendicular to the feed direction. Optionally, the main body 11 may be detachably connected to the tool body, or the main body 11 may be an integral structure with the tool body.
[0034] By providing an avoidance groove 1200 on the end face 120 of the cutting portion 12 in the feed direction, the avoidance groove 1200 can avoid the workpiece during cutting, thereby reducing the risk of machine collision and further reducing the risk of damage to the machine tool and the workpiece.
[0035] In one embodiment of this implementation, please continue to refer to Figure 1 and Figure 2The air avoidance groove 1200 includes a first inclined surface 1201 and a second inclined surface 1202 intersecting each other, and the first inclined surface 1201 is away from the main body 11 relative to the second inclined surface 1202. A first side line 1210 of the first inclined surface 1201 away from the second inclined surface 1202 is connected to the end surface 120, and a second side line 1220 of the second inclined surface 1202 away from the first inclined surface 1201 is connected to the end surface 120. Specifically, an intersection line 1203 formed by the intersection of the first inclined surface 1201 and the second inclined surface 1202 is a straight line and is perpendicular to the axis of the main body 11. By setting the first bevel 1201 and the second bevel 1202, the first bevel 1201 is connected to the end face 120 with a first side line 1210 away from the second bevel 1202, and the second bevel 1202 is connected to the end face 120 with a second side line 1220 away from the first bevel 1201, and the forming difficulty of the air avoidance groove 1200 is relatively low, which is beneficial to reducing the production cost of the knife particle 100.
[0036] In one embodiment of this implementation, please refer to Figure 2 and Figure 3 , Figure 3 yes Figure 1 The schematic diagram of the structure of the blade particle 100 in the top view. The first edge line 1210 and the second edge line 1220 are aligned in a direction perpendicular to the cutting direction. Such a configuration is conducive to ensuring the structural strength of the cutting position of the cutting portion 12 while avoiding the workpiece through the avoidance groove 1200 during cutting.
[0037] In one embodiment of this implementation, please refer to Figure 2 and Figure 3 The cutting portion 12 includes a first cutting edge 121 and a second cutting edge 122, which are arranged on opposite sides of the outer periphery of the main body 11, and each of the first cutting edge 121 and the second cutting edge 122 is provided with an escape groove 1200. Specifically, the first cutting edge 121 and the second cutting edge 122 are centrally symmetrical, and the first cutting edge 121 and the second cutting edge 122 have the same structure. By providing the first cutting edge 121 and the second cutting edge 122, it is convenient to replace the other cutting edge to work after one of the cutting edges is damaged, and the reliability of the knife particle 100 is stronger.
[0038] In this embodiment, the tip width c of the first cutting edge 121 and the second cutting edge 122 is 0.38mm-0.42mm, which can be 0.38mm, 0.39mm, 0.4mm and 0.42mm, etc., preferably 0.4mm. The tip angle α of the first cutting edge 121 and the second cutting edge 122 is 56°-64°, which can be 56°, 59°, 60°, 63° and 64°, etc., preferably 60°. The tip radius R1 of the first cutting edge 121 and the second cutting edge 122 is 0.03mm-0.07mm, specifically 0.03mm, 0.04mm, 0.05mm, 0.06mm and 0.07mm, etc., preferably 0.05mm. The thickness u of the cutting portion 12 is 3mm-3.3mm, and can be 3mm, 3.1mm, 3.12mm, 3.18mm, 3.25mm and 3.3mm, etc., preferably 3.18mm. Through the above parameter settings, the blade 100 has good structural strength and cutting force, and can better avoid the workpiece during cutting.
[0039] In one embodiment of this implementation, please refer to Figure 2 and Figure 3 , the depth h of the air-avoiding groove 1200 is 0.13mm-0.17mm. Specifically, the depth h of the air-avoiding groove 1200 refers to the dimension of the air-avoiding groove 1200 along the axial direction of the main body 11. The depth h of the air-avoiding groove 1200 can be selected as 0.13mm, 0.135mm, 0.14mm, 0.15mm, 0.16mm, 0.17mm, etc. Preferably, the depth h of the air-avoiding groove 1200 is 0.15mm. It can be understood that when the depth h of the air-avoiding groove 1200 is too small, it is not conducive to avoiding the workpiece through the air-avoiding groove 1200 during cutting, and when the depth h of the air-avoiding groove 1200 is too large, it will lead to insufficient structural strength and too short life of the knife grain 100. By setting the depth h of the air-avoiding groove 1200 between 0.13mm-0.17mm, while ensuring the structural strength of the knife grain 100, it can also better avoid the workpiece during cutting to reduce the risk of collision.
[0040] In one embodiment of this implementation, please refer to Figure 2 and Figure 3, the avoidance groove 1200 is constructed as a through groove that runs through both sides of the cutting part 12, and the width d of the opening 1206 of the through groove on the side of the cutting workpiece is 1.8mm-2.2mm. Specifically, the through groove on one side of the cutting workpiece refers to the side where the cutting part 12 rotates relative to the workpiece during cutting, and the cutting part 12 contacts the workpiece to implement cutting. The width d of the opening 1206 can be selected as 1.8mm, 1.9mm, 1.94mm, 2mm, 2.1mm, 2.2mm, etc. Preferably, the width d of the opening 1206 is 2mm. It can be understood that when the width d of the opening 1206 is too small, it is not conducive to avoiding the workpiece through the avoidance groove 1200 during cutting, and when the width d of the opening 1206 is too large, it will lead to insufficient structural strength and a short life of the knife particle 100. By setting the width d of the opening 1206 in the range of 1.8 mm to 2.2 mm, the structural strength of the blade particle 100 can be ensured while avoiding the workpiece during cutting to reduce the risk of collision.
[0041] In one embodiment of this implementation, please refer to Figure 2 and Figure 3 The outer peripheral side of the cutting part 12 is provided with a chip groove 1205, and the chip groove 1205 is used to discharge the chips generated when the blade 100 cuts the workpiece. Specifically, the chip groove 1205 is provided on the side of the cutting part 12 that cuts the workpiece. The groove surface of the chip groove 1205 is arc-shaped, which is conducive to the chips curling through the chip groove 1205 and being discharged from the chip groove 1205. The provision of the chip groove 1205 is conducive to ensuring the smooth progress of thread processing.
[0042] In one embodiment of this implementation, please refer to Figure 2 and Figure 3 The main body 11 is provided with a mounting hole 101, and the mounting hole 101 is used to connect with the tool body. Specifically, the mounting hole 101 is a stepped hole, so that the tool body can be positioned and mounted through the mounting hole 101 and the blade particle 100.
[0043] The present invention also provides a tool (not shown). Figure 1 The tool includes a tool body (not shown) and a blade particle 100 provided in an embodiment of the utility model, and the main body 11 of the blade particle 100 is connected to the tool body. Specifically, the tool body is used to be installed on a machine tool. By adding the blade particle 100 provided in an embodiment of the utility model to the tool, the risk of the tool colliding with the machine when processing threads can be reduced, thereby reducing the risk of damage to the machine tool and the workpiece.
[0044] The utility model embodiment also provides a machine tool, which includes a machine tool body and a tool provided by the utility model embodiment, and the tool body of the tool is installed on the machine tool. Specifically, the machine tool can be a turning and milling compound machine tool. By setting and adding the tool provided by the utility model embodiment to the machine tool, the risk of the machine tool colliding when processing threads can be reduced, thereby reducing the risk of damage to the machine tool and the workpiece.
[0045] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model.
