Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of drilling tools, and in particular relates to a cutting tool for drilling plastics. Background Art
[0002] In the prior art, when cutting plastic materials, a spiral drilling tool for metal drilling is often used. This type of tool is mainly used for drilling cuttings of hard materials such as metals. In order to ensure the strength of the tool when processing hard materials, the tool spiral angle is often designed to be 35 degrees and the tool blade width is designed to be 1.4MM. However, when this type of spiral tool is used to process plastic materials such as ABS, PP, and PE, due to the characteristics of plastic material debris that are easy to roll up and difficult to break, it is easy to have insufficient chip removal capacity, and plastic debris blocks the spiral groove, affecting the plastic processing efficiency. This problem is particularly prominent in high-speed cutting, which seriously affects the processing speed and processing quality.
[0003] For this purpose, it is necessary to have cutting tools specifically designed for plastic processing. Utility Model Content
[0004] In order to solve the above problems existing in the prior art, the present invention provides a cutting tool for plastic drilling.
[0005] The technical solution adopted by the utility model is:
[0006] A cutting tool for drilling plastics, comprising a drill shank and a drill body; the drill shank is connected to the front end of the drill body; the drill body is provided with a spiral groove and a spiral blade back, a blade band is arranged on one side of the blade back, and a secondary blade is arranged on the side of the blade band away from the blade back; the helicity of the spiral groove is 20°±1°; the width of the blade back is 1.25mm±0.01mm.
[0007] As an alternative or supplement to the above cutting tool: a drill tip is arranged at the front end of the drill body, a cutting edge is arranged at the drill tip, the back angle of the cutting edge is 13°, and the front angle of the cutting edge is 5°.
[0008] As an alternative or in addition to the above-mentioned cutting tool: the length of the drill body is 10 cm.
[0009] As an alternative or supplement to the above cutting tool: the length of the spiral groove is 13 cm.
[0010] As an alternative or supplement to the above cutting tool: the chisel edge length at the front end of the drill body is 0.06 mm.
[0011] As an alternative or in addition to the above cutting tools: the diameter of the drill shank and the drill body is 3 mm.
[0012] As an alternative or in addition to the above cutting tool: the total length of the cutting tool is 38.5 mm.
[0013] The beneficial effects of the utility model are:
[0014] 1. The material of the cutting tool in this scheme is an alloy material composed of tungsten, cobalt, carbon and other elements; because this material has high hardness, high wear resistance, heat resistance and corrosion resistance, as well as good impact resistance, it can effectively improve the structural strength of the cutting tool;
[0015] 2. The spindle speed of 30,000 rpm and above can achieve high-speed and efficient cutting performance, especially in the processing of plastic products (product materials: ABS, PP, PE, etc.), with extremely high-speed and efficient cutting capabilities and excellent chip removal performance.
