Description

Technical Field

[0001] This utility model relates to the field of forming milling cutter technology, specifically a milling cutter with chip removal function. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. 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. With the widespread use of milling cutters in machining, the demand for milling cutters with chip removal functions is increasing.

[0003] However, it still has some drawbacks. For example, when traditional milling cutters are used for machining, the chips they cut tend to stick to the milling cutter. This is partly due to excessive wear of the cutting edge, which causes the chips to curl and stick to the milling cutter. On the other hand, during the chip removal process, the chips accumulate around the milling groove, making effective chip removal impossible. At the same time, excessive chip accumulation will also affect the machining efficiency of the milling cutter. Furthermore, when the milling cutter is fixed and clamped to the machine tool, it is inserted into the fixture and then fixed with a nut, which is relatively inconvenient to operate.

[0004] To address the aforementioned problems, this application proposes a milling cutter with chip removal function. Utility Model Content

[0005] The purpose of this utility model is to provide a milling cutter with chip removal function to solve the problems mentioned in the background art. In the prior art, the chips cut by the milling cutter are easy to get stuck on the milling cutter. On the one hand, excessive wear of the cutting edge causes the chips to curl and get stuck on the milling cutter. On the other hand, during the chip removal process, the chips accumulate around the milling groove, making effective chip removal impossible. At the same time, excessive chip accumulation will also affect the processing efficiency of the milling cutter. Furthermore, when the milling cutter is fixed and clamped to the machine tool, it is inserted into the fixture and then fixed with a nut, which is inconvenient to operate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a milling cutter with chip removal function, comprising a milling cutter body, the outer wall of the milling cutter body being provided with six sets of milling cutter cutting edges, each set of milling cutter cutting edges being provided with an equidistant spacing, the spacing formed by the milling cutter cutting edges being a milling cutter chip removal groove, the front end outer surface of the milling cutter body being provided with heat dissipation holes, the outer wall of the milling cutter body being provided with an arc-shaped chip breaking groove, and the milling cutter chip removal groove and the arc-shaped chip breaking groove being interconnected.

[0007] Preferably, a baffle is fixedly connected to the rear outer surface of the milling cutter body, and a positioning rod is fixedly connected to the rear outer surface of the baffle.

[0008] Preferably, the chip removal direction of the milling cutter chip removal groove is clockwise, and the chip removal direction of the arc-shaped chip breaking groove is counterclockwise.

[0009] Preferably, the upper and lower outer surfaces of the positioning rod are movably connected to semi-circular movable blocks.

[0010] Preferably, the upper and lower outer surfaces of the positioning rod are provided with fixing grooves, and a sleeve and a telescopic rod are fixedly connected in the inner cavity of the fixing groove. The sleeve is located on the lower outer surface of the telescopic rod, and the sleeve and the telescopic rod are movably connected.

The spacing formed by the milling cutter cutting edges 2 is a milling cutter chip removal groove 3. A heat dissipation hole 4 is opened on the outer surface of the front end of the milling cutter body 1, and an arc-shaped chip breaking groove 5 is opened on the outer wall of the milling cutter body 1. The milling cutter chip removal groove 3 and the arc-shaped chip breaking groove 5 are connected. Its overall structure is simple and easy to install and operate.

[0021] In this embodiment, as Figures 2-3 As shown, a baffle 6 is fixedly connected to the outer rear end of the end mill body 1, and a positioning rod 7 is fixedly connected to the outer rear end of the baffle 6. The chip removal direction of the chip removal groove 3 is clockwise, and the chip removal direction of the arc-shaped chip breaking groove 5 is counterclockwise.

[0022] Working principle:

[0023] A milling cutter with chip removal function, during machining, firstly, when the milling cutter body 1 rotates at high speed to mill grooves, the workpiece is quickly cut by the milling cutter cutting edge 2. After cutting, the waste chips are discharged from the milling groove through the milling cutter chip removal groove 3 provided on the milling cutter body 1. At the same time, during the chip removal process, the waste chips can be quickly broken by the provided arc-shaped chip breaking groove 5, which effectively prevents the waste chips from sticking on the milling cutter body 1, reduces the occurrence of waste chips rolling and accumulating on the milling cutter body 1, and affects the milling efficiency. In addition, the provided semi-circular movable block 8 can quickly install the milling cutter body 1 when it is installed on the machine tool fixture, making the operation simple and quick.
