Description

Technical Field

[0001] This utility model relates to the field of milling cutter equipment technology, and in particular to a saw blade alloy milling cutter. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling. During operation, each cutting tooth sequentially and intermittently removes the excess material from the workpiece. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces. There are many types of milling cutters, and each milling cutter is made of different materials. Currently, in the process of working, the shank of a carbide milling cutter drives the milling cutter insert to rotate at high speed. Therefore, the milling cutter inserts are manufactured with a center of symmetry. After the high-speed rotating milling cutter insert comes into contact with the workpiece, it will mill the workpiece.

[0003] The applicant discovered through a search that a Chinese patent discloses "An Alloy End Mill that is Easy to Disassemble and Assemble," with publication (announcement) number "CN222058935U." This patent mainly achieves the disassembly and assembly of the end mill and the connecting shank through a set of mounting components. However, during the cutting process, metal friction and pressure generate a large amount of heat. Especially when performing high-load, high-speed machining, the surface temperature of the end mill is prone to rise, leading to overheating. Excessive temperature will reduce the hardness of the tool, increase tool wear, and thus reduce machining accuracy and surface quality. Therefore, we propose an alloy end mill for saw blades. Utility Model Content

[0004] The purpose of this utility model is to provide a saw blade alloy end mill to solve the problem mentioned in the background art that during the cutting process, metal friction and pressure will generate a lot of heat. Especially when performing high-load and high-speed machining, the surface temperature of the end mill is prone to rise, leading to overheating of the end mill. Excessive temperature will reduce the hardness of the tool, increase tool wear, and thus reduce machining accuracy and surface quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a saw blade alloy milling cutter, comprising a mounting plate, a milling cutter structure, and a mounting structure. The milling cutter structure is mounted on the mounting plate via the mounting structure. The milling cutter structure includes a milling cutter, a cutter holder, a mounting block, a stop, and an auxiliary plate. The mounting block and the stop are respectively fixedly mounted at the junction of the cutter holder and the milling cutter. The auxiliary plate is fixedly mounted on the side wall of the milling cutter. The mounting block has several through holes. The cutter holder has an internal cavity. A sealing cap is threaded onto the top of the cutter holder. A flow groove is provided between the cutter holder and the milling cutter. A miniature solenoid valve is installed in the flow groove near the cavity. The mounting structure includes a frame, a motor, a coupling, and a connecting sleeve. The frame is fixedly mounted on the top of the mounting plate. The motor is fixedly mounted on the bottom of the frame. The connecting sleeve is rotatably mounted in the middle position of the mounting plate.

[0006] As a preferred embodiment, the milling cutter is fixedly mounted at the bottom end of the tool holder, the stop is at the top end of the mounting block, and the auxiliary plate is fixedly connected to the mounting block and the stop respectively.

[0007] As a preferred embodiment, the flow groove is disposed inside the milling cutter and is configured in a spiral shape, the top end of the flow groove is connected to the cavity, and the bottom end of the flow groove extends to the outer side of the bottom of the milling cutter.

[0008] As a preferred embodiment, the motor shaft of the motor is connected by a coupling and a connecting sleeve.

[0009] As a preferred embodiment, a slide rail is fixedly installed inside the connecting sleeve, and bolts are threaded onto the side wall of the connecting sleeve.

[0010] As a preferred embodiment, the side wall of the tool holder is provided with a slide groove that matches the slide rail, and the side wall of the tool holder is provided with a plurality of limiting holes, the limiting holes and bolts cooperating with each other.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the designed milling cutter structure, the coolant in the cavity flows into the flow channel. The coolant flows in a spiral motion in the flow channel, which increases the flow rate and flow path of the coolant, and can more effectively remove the heat generated during the cutting process. When the milling cutter rotates, under the action of the auxiliary plates, it can gather air between two adjacent auxiliary plates. At this time, some air will flow away from the adjacent auxiliary plates, and some air will pass through the through hole and contact the milling cutter, realizing the auxiliary cooling of the milling cutter. This can effectively control the temperature of the milling cutter, reduce thermal deformation and wear, and extend the service life of the tool.

[0013] 2. The mounting structure includes bolts that extend into the limiting holes, allowing the tool holder to be installed into the connecting sleeve, and subsequently, the milling cutter. The presence of multiple limiting holes allows for varying distances the tool holder extends into the connecting sleeve, enabling precise adjustment of the tool holder's extension distance to suit actual machining needs. This adjusts the working length of the milling cutter, simplifying the installation and disassembly process of the tool holder and connecting sleeve.

[0014] The tool holder can be precisely positioned and fixed by rotation, making it easy to operate and suitable for high-efficiency production environments. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0025] Please refer to Appendix 1. Figure 5 A saw blade alloy end mill includes a mounting plate 1, an end mill structure 2, and a mounting structure 3. The end mill structure 2 is mounted on the mounting plate 1 via the mounting structure 3. The mounting plate 1 holds the end mill structure 2 and the mounting structure 3 in the desired positions. The end mill structure 2 includes an end mill 21, a tool holder 22, a mounting block 23, a stop 24, and an auxiliary plate 25. The end mill 21 is fixedly mounted on the bottom end of the tool holder 22. The mounting block 23 and the stop 24 are respectively fixedly mounted at the junction of the tool holder 22 and the end mill 21.

[0026] At the top of the mounting block 23, an auxiliary plate 25 is fixedly mounted on the side wall of the milling cutter 21, and the auxiliary plate 25 is fixedly connected to the mounting block 23 and the stop 24 respectively. The mounting block 23 has several through holes 26. A cavity 27 is provided inside the tool holder 22. A sealing cap 29 is threaded onto the top of the tool holder 22, sealing the cavity 27. The cavity 27 is filled with coolant. A flow groove 28 is provided between the tool holder 22 and the milling cutter 21. The flow groove 28 is inside the milling cutter 21 and is spiral-shaped. The top of the flow groove 28 communicates with the cavity 27, and the bottom of the flow groove 28 extends to the bottom outer side of the milling cutter 21. A miniature solenoid valve is installed inside the flow groove 28 near the cavity 27. The miniature solenoid valve controls the flow of coolant from the cavity 27 into the flow groove 28. The flow groove 28 is spiral-shaped, increasing the flow between the milling cutter 21 and the cavity 21. This increases the contact area, thereby improving the cooling effect on the milling cutter 21.

[0027] Specifically, in the milling cutter structure 2, the coolant in the cavity 27 flows into the flow groove 28. The coolant flows spirally in the flow groove 28, which increases the flow rate and flow path of the coolant, and can more effectively remove the heat generated during the cutting process. When the milling cutter 21 rotates, under the action of the auxiliary plate 25, the air can be gathered between the two adjacent auxiliary plates 25. At this time, some air will flow away from the adjacent auxiliary plates 25, and some air will pass through the through hole 26 and contact the milling cutter 21, realizing the auxiliary cooling of the milling cutter 21. This can effectively control the temperature of the milling cutter 21, reduce thermal deformation and wear, and extend the service life of the tool. Example 2:

[0028] Please refer to Figures 1-7. Based on Embodiment 1, the mounting structure 3 includes a frame 31, a motor 32, a coupling 33, and a connecting sleeve 34. The frame 31 is fixedly mounted on the top of the mounting plate 1, the motor 32 is fixedly mounted on the bottom of the frame 31, and the connecting sleeve 34 is rotatably mounted in the middle position of the mounting plate 1. The motor shaft of the motor 32 is connected to the connecting sleeve 34 through the coupling 33. The motor shaft of the motor 32 drives the connecting sleeve 34 to rotate in the mounting plate 1 through the coupling 33. A slide rail 35 is fixedly mounted inside the connecting sleeve 34, and bolts 36 are threaded on the side wall of the connecting sleeve 34. The side wall of the tool holder 22 is provided with a sliding groove 37 that matches the slide rail 35. The side wall of the tool holder 22 is provided with a plurality of limiting holes 38, and the limiting holes 38 and bolts 36 cooperate with each other.

[0029] Specifically, through the installation structure 3, the bolt 36 extends into the limiting hole 38, thereby installing the tool holder 22 into the connecting sleeve 34, and then installing the milling cutter 21. By setting several limiting holes 38, the distance from which the tool holder 22 extends into the connecting sleeve 34 can be different. According to the actual processing needs, the extension distance of the tool holder 22 can be precisely adjusted, thereby adjusting the working length of the milling cutter 21. This simplifies the installation and disassembly process of the tool holder 22 and the connecting sleeve 34. The tool holder 22 can be accurately positioned and fixed by rotating the bolt 36. The operation is simple and suitable for high-efficiency production environments.

[0030] The working principle of this utility model is as follows: The mounting plate 1 is installed in the required position. The sealing cap 29 is unscrewed using a tool and removed from the tool holder 22. Coolant is then injected into the cavity 27. The sealing cap 29 is then screwed back on to seal the cavity 27. The slide groove 37 and slide rail 35 on the tool holder 22 are aligned, and the tool holder 22 is inserted into the connecting sleeve 34. The limiting hole 38 and bolt 36 are aligned, and the bolt 36 is tightened. The bolt 36 moves threadedly within the connecting sleeve 34, extending into the limiting hole 38, thus installing the tool holder 22 into the connecting sleeve 34. This, in turn, installs the milling cutter 21. By providing several limiting holes 38, the distance the tool holder 22 extends into the connecting sleeve 34 varies, thereby adjusting the installation distance of the tool holder 22 and, consequently, the extension distance of the milling cutter 21.

[0031] The motor 32 is started, and the motor shaft of the motor 32 drives the coupling 33 to rotate. The coupling 33 drives the connecting sleeve 34 to rotate, and the connecting sleeve 34 drives the milling cutter 21 to rotate through the tool holder 22. The milling cutter 21 performs machining. When the milling cutter 21 is machining, the micro solenoid valve is opened, so that the flow grooves 28 are interconnected. The coolant in the cavity 27 flows into the flow grooves 28. The coolant flows spirally in the flow grooves 28, thereby cooling the milling cutter 21. The flow grooves 28 are set in a spiral shape to increase the contact area between the coolant and the milling cutter 21 and improve the cooling efficiency. When the milling cutter 21 rotates, under the action of the auxiliary plate 25, the air can be gathered between two adjacent auxiliary plates 25. At this time, some air will flow away from the adjacent auxiliary plates 25, and some air will pass through the through hole 26 and contact the milling cutter 21, realizing the auxiliary cooling of the milling cutter 21.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of this utility model and is not intended to be construed as a complete invention.

[0033] To limit the scope of this utility model, although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
