Problems solved by technology

Improper control of the welding temperature will cause strength damage to the tissue in the blade and the blade body: the blade is heated without pressure during welding, which is very different from the high-pressure heating during blade molding and sintering, which will cause strength damage to the blade tissue and even cracks; After the cutter body is reheated, its hardness and strength also decrease significantly

Abstract

The invention relates to a blade-detachable steel plate drill, which includes a blade and a cutter body. Several blades are combined into a cutting edge system. The cutter body is provided with several chip removal grooves. Each chip removal groove corresponds to a blade. The mounting part matches the positioning structure on the cutter body, and the blade is detachably installed on the cutter body. There are two kinds of positioning structures, and there are two corresponding types of blades. One of the positioning structures is a cuboid positioning groove, and the corresponding blade mounting part is placed in the positioning groove and fixed on the cutter body with screws; the other positioning structure includes Positioning elastic groove, matching elastic groove, nut, the upper part of the positioning elastic groove is symmetrical ∑ shape and cooperates with the corresponding blade fixing part, the lower part of the positioning elastic groove is connected with the upper part, the nut is placed in the matching elastic groove, and the blade fixing part snaps into the positioning elastic The upper section of the groove is fixed on the cutter body. The invention is reasonable in design, concise and practical. Through the replaceable blade structure, different blades can be installed, which is flexible and diverse, saves time and improves efficiency.

Description

technical field [0001] The invention relates to a blade detachable steel plate drill, which belongs to a ring-shaped cutting drill bit. Background technique [0002] The structural design of the currently commonly used steel plate drills is not reasonable enough, the firmness is poor, the processing is difficult, the processing cost is high, the processing efficiency is low, and the resources are difficult to be rationally and fully utilized. Most similar products on the market now use brazing to connect the blade with the cutter body. Improper control of the welding temperature will cause strength damage to the tissue in the blade and the blade body: the blade is heated without pressure during welding, which is very different from the high-pressure heating during blade molding and sintering, which will cause strength damage to the blade tissue and even cracks; After the cutter body is reheated, its hardness and strength also decrease significantly.
