Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of milling cutter manufacturing, in particular to a multi-angle milling cutter used for automobiles. Background Art
[0002] There is a Chinese invention patent application with application number CN202010192800.3 and titled "Milling Cutter", which discloses a milling cutter, including a shank, a plunge milling cutter connected to the shank, and a dovetail cutter head connected to the plunge milling cutter part, wherein the plunge milling cutter part is a four-edge plunge milling cutter, and the dovetail cutter head is a two-edge dovetail cutter with staggered edges. However, the milling cutter is not easy to handle the gate position of a two-color plastic mold product, and there is still room for improvement, so the structure of the milling cutter needs to be further improved. Summary of the invention
[0003] The technical problem to be solved by the utility model is to provide a multi-angle milling cutter for automobiles that can cut products at multiple angles, conveniently process product gates, and has good processing effects, in view of the above-mentioned existing technical status.
[0004] The utility model solves the above technical problems by adopting the following technical solution: the multi-angle milling cutter for automobiles comprises a cutter head and a cutter handle, and is characterized in that the cutter head comprises a side cutting portion and a tapered head, the side cutting portion is connected to the cutter handle, and the side cutting portion is smoothly connected to the tapered head.
[0005] As an improvement, the side cutting portion may preferably include a cylinder and cutting sharp strips spaced apart on the outer wall of the cylinder, and a chip guide groove is provided on the side wall of the side cutting portion between any two cutting sharp strips.
[0006] As a further improvement, the cutting tips may preferably be arranged in a spiral shape, and the outer wall of the radial cross section of the cutting tips may be an involute.
[0007] As a further improvement, the cutting tip strips may be preferably arranged axially, and the tips of the cutting tip strips are located on the same virtual circle.
[0008] As a further improvement, the chip guide groove may preferably be an arc-shaped groove.
[0009] As a further improvement, the inner wall of the radial cross section of the chip guide groove may also be an involute curve.
[0010] As an improvement, the top end of the conical head may preferably be a plane.
[0011] As a further improvement, the side wall slope of the conical head may preferably be 30°.
[0012] As an improvement, the ratio of the height of the conical head to the total height of the cutter head may preferably be 0.25 to 0.3.
[0013] As a further improvement, the length ratio of the cutter head to the cutter handle may preferably be 0.28 to 0.32, and the sum of the lengths of the cutter head and the cutter handle is 69 to 90 mm.
[0014] Compared with the prior art, the utility model has the following advantages: by changing the shape of the cutter head, milling in various angles can be achieved; the cutter head is arranged on the cutter handle, and by increasing the length of the cutter handle, products of different heights can be milled; the cutter head includes a side cutting portion and a tapered head; the angle of the cutter head can meet the multi-angle milling of the product, and the tip position can meet the product gate cutting; special tools for milling two-color plastic mold products, shape modeling angles and gate milling, can be used, clean and burr-free; the tapered barrel mainly mills the side wall of the product, and the side cutting portion mills the material head gate.
