Description

Technical Field

[0001] This utility model relates to the field of milling cutter technology, specifically a high-hardness, high-temperature alloy milling cutter with an indexable insert. Background Technology

[0002] Some special products require the production of high-temperature alloy materials, such as turbine blades used in automobiles. During the processing of high-temperature alloy materials, the temperature generated by cutting accumulates on the machined surface and at the cutting edge, causing the temperature to rise. Furthermore, due to the high strength of high-temperature alloy materials, the cutting edge of the milling cutter used to process high-temperature alloy materials is prone to breakage, which greatly reduces the service life of the milling cutter.

[0003] A search revealed a high-hardness alloy end mill with authorization publication number CN215786991U for rapid cutting of high-temperature alloy materials. The end mill includes a cutter body, a cutter shaft that mates with the cutter body and the equipment, and a cooling structure for cooling the cutter surface. The cutter body is spherically shaped, and a condensate tank is provided inside the cutter body corresponding to the chip removal groove. A screw is integrally provided at the mounting end of the cutter body, and a threaded groove is provided on the cutter shaft corresponding to the screw. The cutter body is helically mounted to the screw and the threaded groove. The cooling structure includes a telescopic branch pipe and a sponge head for discharging cutting fluid. The mounting end of the sponge head is connected to the end of the telescopic branch pipe via a mounting base. This high-hardness alloy end mill for rapid cutting of high-temperature alloy materials, with its spherical cutting edge, facilitates cutting of high-temperature alloy materials while reducing the cutting resistance of the cutting edge and cooling the cutting operation of the cutter body.

[0004] The high-hardness alloy end mill in the above-mentioned technical solution for rapid cutting of high-temperature alloy materials uses a spherical cutting edge to cut the high-temperature alloy material according to the curvature of the spherical cutting edge. This facilitates the machining and cutting of high-temperature alloy materials while reducing the resistance of the cutting edge to the material and cooling the cutting operation of the end mill body. However, this method does not take into account the impact of vibration generated during the end mill's operation on the machining process, which leads to a decrease in machining quality and a shortened tool life. Therefore, we provide an indexable insert type high-hardness alloy end mill. Utility Model Content

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1

[0029] Please see Figures 1 to 3 This is the first embodiment of the present invention. This embodiment provides an indexable insert type high-temperature alloy high-hardness end mill, including: an end mill body 1, a base assembly 2 at the upper end of the end mill body 1, the base assembly 2 including a base side shell 21 detachably mounted on the side of the end mill body 1, a limiting groove 26 is formed inside the base side shell 21, a shock absorption assembly 3 is provided inside the limiting groove 26, and the shock absorption assembly 3 includes a second fixing seat 34 detachably mounted at the end of the end mill body 1;

[0030] Several dampers 32 are detachably mounted on the surface of the second fixed seat 34. The end of the damper 32 is detachably mounted on the first fixed seat 31. Springs 33 are fixedly connected to the surfaces of the first fixed seat 31 and the second fixed seat 34 on the outside of each damper 32.

[0031] Specifically, a base body 22 is fixedly installed above the first fixed seat 31. A fixing bolt 23 is installed through the surface of the base body 22. A fixing groove 25 is provided inside the side shell 21 of the base. A fixing protrusion 24 is fixedly installed inside the fixing groove 25 on the upper side of the milling cutter body 1.

[0032] Furthermore, the engagement between the fixing protrusion 24 and the fixing groove 25 can prevent the milling cutter body 1 from falling off the base side shell 21.

[0033] When the milling cutter vibrates during operation, the vibration is transmitted along the milling cutter body 1 to the base assembly 2. The vibration is mitigated by the damping component 3 provided on the inner side of the base assembly 2. When the vibration is transmitted, the dampers 32 on the surface of the first fixed seat 31 and the second fixed seat 34 work together with the spring 33 to mitigate the vibration. At the same time, the fixing protrusion 24 provided on the side of the milling cutter body 1 moves inside the fixing groove 25 provided on the side shell 21 of the base. The base body 22 and the side shell 21 of the base can be detached and installed by fixing bolts 23.

[0034] In summary, by setting up the vibration damping component 3, the impact of vibration generated during the milling cutter's operation on the milling cutter's machining can be reduced, thereby preventing problems such as decreased machining quality and shortened tool life caused by vibration. Example 2

[0035] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 This is the second embodiment of the present invention, which provides an improved design for an indexable insert type high-hardness alloy end mill.

[0036] Specifically, a milling cutter head 4 is fixedly installed at the bottom of the milling cutter body 1, and a movable insert 5 is detachably installed on the side of the milling cutter head 4. A fixing component 6 is installed on both the surface and the interior of the milling cutter head 4. The fixing component 6 includes a square fixing groove 64 formed on the surface of the milling cutter head 4. A square fixing element 63 is detachably installed inside the square fixing groove 64. A fixing screw groove 62 is provided inside the milling cutter head 4, and a fixing screw 61 is installed through the surface of the movable insert 5.

[0037] Furthermore, the engagement between the fixing component 6 and the milling head 4 allows the movable insert 5 to be fixed on the surface of the milling head 4, and the position of the movable insert 5 can be moved for better machining.

[0038] Specifically, a cooling assembly 7 is installed inside the milling cutter body 1, the base body 22, the limiting groove 26, and the milling cutter head 4. The cooling assembly 7 includes a cooling pipe 71 fixedly installed inside the base body 22, the limiting groove 26, and the milling cutter body 1. A diversion groove 72 is opened below the cooling pipe 71 inside the milling cutter head 4. A conveying groove 73 is opened around the diversion groove 72 inside the milling cutter head 4. Cooling holes 74 are opened around the conveying groove 73 inside the milling cutter head 4 and the movable insert 5.

[0039] Furthermore, the cooling component 7 can spray coolant onto the surface of the milling cutter during milling to cool it down, preventing excessive temperature from reducing machining accuracy and increasing milling cutter wear.

[0040] In use, a movable insert 5 is detachably mounted on the surface of the milling cutter head 4, which is fixedly installed at the end of the milling cutter body 1. The movable insert 5 is fixed to the surface of the milling cutter head 4 by a fixing component 6. The surface of the milling cutter head 4 is provided with a square fixing groove 64, and a square fixing element 63 is detachably installed inside the square fixing groove 64. The fixing screw 61 passes through the fixing screw groove 62 and the square fixing element 63 to fix the movable insert 5 to the surface of the milling cutter head 4. The square fixing element 63 is fixed inside the square fixing groove 64. When it is necessary to move the movable insert 5, the square fixing element 63 is fixed inside the square fixing groove 64. The fixed element 63 moves inside the square fixed groove 64, and at the same time moves the movable blade 5 and the fixed screw 61, so that the moved movable blade 5 is fixed again on the surface of the milling head 4. When cooling is required, the external coolant enters the diversion groove 72 located inside the milling head 4 through the cooling pipe 71. The diversion groove 72 is surrounded by a conveying groove 73. After passing through the diversion groove 72, the external coolant passes through the conveying groove 73 and sprays the movable blade 5 on the surface of the milling head 4 through the cooling hole 74 to reduce the temperature of the movable blade 5.

[0041] In summary, through the cooperation between the fixing component 6 and the milling head 4, the movable insert 5 can be fixed on the surface of the milling head 4, and the position of the movable insert 5 can be moved for better machining. Through the cooling component 7, coolant can be sprayed on the surface of the milling insert during milling to cool it down, preventing the problem of reduced machining accuracy and increased milling cutter wear caused by excessive temperature.
