Embodiment

[0033] The processing method steps of insert type cemented carbide drill bit, comprise,

[0034] One, the selection of blade, because drill bit belongs to rough machining tool, so should select strength and impact resistance material when selecting blade material, the present invention determines to select blade material by Co content 10% standard; Determine the proportional relation of blade thickness and drill bit diameter The following table: (unit: mm)

[0035] Specification Φ12 Φ13 Φ14~Φ15 Φ16 Φ17~Φ18 Φ19 Φ20~Φ21 Φ22 Φ23~Φ24 Φ25 Blade Thickness 4mm 4.5mm 5mm 5.5mm 6mm 6.5mm 7mm 7.5mm 8mm 8.5mm

[0036] 2. For the grinding of chip volume and chip breaker of the cutter segment, according to the technical standard for processing steel drill bit chip breaker, use a five-axis tool grinder (model DECKEL S22), set: if the hole depth of the workpiece reaches 3 times The diameter of the drill bit, the edge inclination angl...

Abstract

The invention relates to an imbedded carbide drill for a steel piece and a processing method, wherein the imbedded carbide drill for the steel piece is structurally a cutter body which is connected between a carbide blade and a shank; the front end part of the cutter body is connected with the carbide blade, a cuttings reeling slot is arranged between the tool nose of the cutter body and an auxiliary chamfered edge of a peripheral blade, the rear part of the cuttings reeling slot is connected with a cuttings-breaking groove, the center of the carbide blade is provided with a blade drilling core, a cutter slot is formed in the top of the cutter body, and a cutter body core is arranged at the center of the cutter slot. The processing method comprises of 1, selecting the blade; 2, cuttings reeling of a blade section and grinding of the cuttings-breaking groove; 3, grooving a steel body; 4, preparing a tool section for the carbide blade; 5, cutting the tool section through wire-electrode cutting; 6, lathing the cutter body through a lathe; 7, milling the cutter body through a milling machine; 8, milling the cutter slot through the milling machine; 9, heat treating; 10, welding; 11, grinding the carbide blade through a tool; and 12, coating TiAlN. The imbedded carbide drill has the advantages that steel piece processing and cuttings are automatically reeled, broken and removed, the material consumption is 1 / 20 of the existing material consumption, the cost performance is greatly increased, and the imbedded carbide drill has great economic and social benefits.

Description

technical field [0001] The invention relates to an insert type cemented carbide drill for steel parts and a processing method thereof. Background technique [0002] Inserted carbide drills are usually used in processing aluminum alloys and cast iron materials in China. This technology has been used for decades, the technology is mature, and relevant standards have been formed. But this type of tool has not been used in processing steel materials so far. At present, the drill bits for processing steel materials in the same industry at home and abroad, one is a high-speed steel drill bit for low-speed cutting of ordinary machine tools, and the other is a solid carbide drill bit for high-speed cutting in CNC machine tools. Especially when drilling holes with solid carbide drill bits, the cost of materials is high and the waste of resources is serious. [0003] my country's insert cemented carbide drills can only process general easy-cut materials such as aluminum alloy and ca...
