Description

Technical Field

[0001] The utility model relates to a milling cutter, in particular to a straight groove round nose cutter capable of quickly removing chips, belonging to the technical field of straight groove round nose cutters. Background Art

[0002] In the mechanical manufacturing and metal processing industries, milling cutters are common cutting tools used to remove material from workpieces to form the desired shape and size. As a special type of milling cutter, straight groove round nose cutters have their own unique cutting characteristics and application scenarios.

[0003] During the cutting process, the existing straight groove round nose cutters often cause increased cutting temperature, increased tool wear, and reduced processing accuracy due to chip accumulation and blockage. For example, in the processing of high-strength or high-viscosity materials, chips are easily accumulated and blocked in the cutting groove, resulting in increased cutting force and increased cutting temperature, which in turn affects the tool life and processing quality.

[0004] A round nose cutter with announcement number CN219402478U includes a shank and a cutting part; the cutting part is arranged at one end of the shank. When there are a lot of waste chips in one of the chip grooves, the pressure of the waste chips in the chip groove connected to the chip groove entering the chip groove will increase, and the waste chips can be discharged from other chip grooves and chip grooves to avoid a large amount of waste chips accumulating or even clogging in the chip groove.

[0005] In the above technical solution, when there are more waste chips in one of the chip grooves, the pressure of the waste chips in the chip groove connected to the chip groove entering the chip groove will increase, and the waste chips can be discharged from other chip grooves and chip grooves. However, a fixed integrated structure is adopted between the cutting part and the shank. After long-term use, when the cutting part is worn, the cutting part and the shank need to be replaced together, which increases the cost for the user. For this reason, we provide a straight groove round nose cutter that can quickly evacuate chips. Utility Model Content

[0006] In order to solve the problem that a fixed integrated structure is adopted between the cutting part and the handle, which means that after long-term use, when the cutting part is worn, the cutting part and the handle need to be replaced together, thereby increasing the cost for the user, the utility model provides a straight groove round nose cutter that can quickly remove chips.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a straight groove round nose knife capable of rapid chip removal, comprising a first knife handle, a first knife rod fixedly connected to the top of the first knife handle, a chip removal groove evenly opened on the outer periphery of the first knife rod, a knife block mounting groove opened on the top of the chip removal groove, and a cutting knife block fixedly installed outside the knife block mounting groove;

[0008] The outer wall of the cutting block is provided with a block limiting hole, the inner thread of the block limiting hole is provided with a first fixing screw, one side of the outer wall of the block mounting groove is provided with a block fixing hole, and the upper outer wall of the cutting block is provided with a chip removal groove.

[0009] As a further solution of the utility model: a cutting edge is fixedly provided on the top of the chip groove.

[0010] As a further solution of the utility model: a first knife root is fixedly installed below the first knife handle, and a clamping end is provided on the outer periphery of the first knife root.

[0011] As a further solution of the utility model: a connection block fixing hole is opened above the outer wall of the first knife root, and a knife handle connecting block is fixedly connected to the connection between the first knife root and the first knife handle.

[0012] As a further solution of the utility model: the handle connecting block is fixed to the lower end of the first handle, and a spring limiting groove is provided in the center of the handle connecting block.

[0013] As a further solution of the utility model: a blade root fixing hole is provided on the outer wall of the blade handle connecting block, and a second fixing screw is installed on the internal threads of the connecting block fixing hole and the blade root fixing hole.

[0014] As a further solution of the utility model: a spring installation groove is provided at the connection between the first blade root and the first blade handle, the spring installation groove is provided in the center of the first blade root, and a first spring is installed in the spring installation groove.

[0015] The beneficial effects of the utility model are:

[0016] 1. The utility model installs the cutting block in the cutting block installation groove by the first fixing screw, so that the cutting block can be disassembled and replaced. When the cutting block is worn due to long-term use, the user can only replace the cutting block without replacing the entire tool. Since the cutting block is detachable, the user can easily disassemble and replace these parts, which greatly simplifies the maintenance and maintenance process of the tool, thereby significantly reducing the use cost;

[0017] 2. The utility model forms an efficient chip removal function through the evenly arranged chip grooves and the chip withdrawal grooves above the cutting tool block, which can quickly remove the chips generated in the cutting process from the cutting area, reduce the impact of chip accumulation on the cutting process, and improve cutting efficiency and quality. The tool holder connecting block is fixed between the first tool root and the first tool holder by the second fixing screw, and the first spring is installed in the spring mounting groove, which provides additional fixing and shock absorbing effects, making the entire tool structure more solid and able to cope with various forces in the cutting process.
