Technical Field
[0001] This utility model relates to the field of milling technology, specifically to a high-hardness alloy milling cutter with good high-temperature resistance. Background Technology
[0002] Milling is a common machining method. A milling machine fixes the workpiece on a worktable and uses a rotating milling cutter to perform cutting operations. Milling is commonly used for machining materials such as metals and plastics, and can perform various machining operations such as planar, curved, grooving, and hole machining. During milling, operators need to select appropriate tools, machining parameters, and process routes according to the requirements of the workpiece to ensure machining quality and efficiency. Milling is widely used in fields such as machinery manufacturing, aerospace, automotive manufacturing, and mold manufacturing, and is one of the most common machining methods in manufacturing. With the development of CNC technology, CNC milling machines have replaced traditional milling machines as the mainstream, improving machining accuracy and production efficiency, and promoting the development of industrial manufacturing.
[0003] Existing end mills have a large cutting volume during high-speed machining, which increases the cutting load on the end mill and easily leads to overheating, affecting the end mill's service life. To address this, we propose a high-hardness alloy end mill with good high-temperature resistance. Utility Model Content
[0004] The purpose of this invention is to provide a high-hardness alloy end mill with good high-temperature resistance, thereby reducing the machining load on the end mill and solving the problem that existing end mills have a large cutting volume during high-speed machining, which leads to an increased cutting load on the end mill, which in turn easily causes the end mill to heat up and affects its service life.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-hardness alloy end mill with good high-temperature resistance, comprising a taper shank and a cutter head, wherein the taper shank is mounted on the top of the cutter head, and the bottom of the cutter head is provided with a cutting groove near the outer surface. A machining insert is mounted on one side of the cutting groove by a locking screw, and an alloy insert is mounted inside the cutting groove near the machining insert by a clamping groove. A pin discharge groove is provided at the bottom of the cutter head near the cutting groove, and a liquid guiding hole is provided at the top of the taper shank. A flow guiding hole is provided inside the taper shank and the cutter head at the bottom of the liquid guiding hole.
[0006] Preferably, the cutter head has a drain hole located at the guide hole position, and the drain hole is located on one side of the drain groove.
[0007] Preferably, there are four cutting grooves, and the four cutting grooves are respectively located at the bottom of the cutting head near the outer surface.
[0008] Preferably, the liquid guiding hole, the flow guiding hole, and the liquid draining hole are connected, and the diameters of the liquid guiding hole, the flow guiding hole, and the liquid draining hole decrease sequentially.
[0009] Preferably, the top of the cone shank is provided with a connecting hole at the position of the liquid guiding hole, the inner surface of the connecting hole is provided with a sealing groove, and a sealing ring is installed inside the sealing groove.
[0010] Preferably, the drain groove is arc-shaped.
[0011] Preferably, there are a total of twenty-four drainage holes, and the twenty-four drainage holes are equally divided into four groups, with the four groups of drainage holes evenly distributed on one side of the drain groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model reduces the machining load on the milling cutter by setting machining inserts and alloy inserts. This solves the problem that existing milling cutters have a large cutting volume during high-speed machining, which leads to an increased cutting load on the milling cutter and thus easily causes the milling cutter to heat up, affecting its service life. This invention reduces the probability of the milling cutter heating up, thereby improving its service life.
[0014] 2. This utility model achieves efficient cooling of the machining insert by setting guide holes, liquid guide holes and drain holes, thereby solving the problem that in existing milling cutters, the cutting fluid cannot be evenly sprayed onto the machining insert, the machining insert temperature is too high, and the milling cutter is easily damaged. It reduces the milling cutter machining temperature, thereby improving the service life of the milling cutter.
[0015] 3. This utility model achieves the effect of sealing the connection by setting a connecting hole and a sealing ring, thereby solving the problem that the existing cutting fluid is under high pressure during spraying, which makes it easy for the cutting fluid to leak and affect the cooling efficiency of the milling cutter. It ensures normal spraying of cutting fluid and thus reduces the probability of damage to the milling cutter. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] Example 1
[0022] like Figure 1-3 As shown, to achieve the above objectives, this utility model provides the following technical solution: A high-hardness alloy end mill with good high-temperature resistance, comprising a taper shank 1 and a cutter head 2. The taper shank 1 is mounted on the top of the cutter head 2. The bottom of the cutter head 2 is provided with four grooves 3 near the outer surface, and these four grooves 3 are located at the bottom of the cutter head 2 near the outer surface. A pin removal groove 7 is provided on the bottom of the cutter head 2 near the grooves 3. The pin removal groove 7 is arc-shaped to facilitate the removal of iron pins. A liquid guiding hole 10 is provided at the top of the taper shank 1. A flow guiding hole 14 is provided inside the taper shank 1 and the cutter head 2 at the bottom of the liquid guiding hole 10. The cutter head 2 is located at the position of the flow guiding hole 14. There are twenty-four drain holes 6, which are equally divided into four groups. The four groups of drain holes 6 are evenly distributed on one side of the drain groove 7. The drain holes 6 are located on one side of the drain groove 7. The guide hole 10, the flow hole 14 and the drain hole 6 are connected to facilitate the conduction of cutting fluid. The diameters of the guide hole 10, the flow hole 14 and the drain hole 6 decrease in sequence. A machining insert 4 is installed on one side of the tool groove 3 by a locking screw 5. An alloy insert 8 is installed inside the tool groove 3 near the machining insert 4 by a clamping groove 9. The machining insert 4 is used to rough machine the material and the alloy insert 8 is used to finish machine the material.
[0023] The working principle of a high-hardness alloy end mill with good high-temperature resistance based on Embodiment 1 is as follows: After the present invention is installed, it is mounted through the tapered shank 1. During use, the tapered shank 1 is rotated by the equipment, which in turn rotates the cutter head 2, which in turn rotates the machining insert 4 for rough milling. The cutter head 2 then rotates the alloy insert 8 for finish milling. Simultaneously, the cutting fluid is delivered from the guide hole 10 to the guide hole 14, and then from the guide hole 14 to the drain hole 6, and finally discharged through the drain hole 6. This cools the machining insert 4 and the alloy insert 8, thereby extending the service life of the present invention. Thus, the working process of the equipment is completed.
