specific Embodiment approach

[0025] detailed description The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] A high-efficiency forming milling blade for a slewing ring gear tooth profile. According to the shape of the slewing ring gear tooth profile, a heterogeneous tool structure is adopted. According to the distribution of the cutting force on each cutting edge during processing, the The entire cutting edge is reshaped in sections; among them, in order to reduce the cutting force, a sharp edge is used on the side edge of the blade, and proper rounding protection is carried out; a special structure is adopted in the forming arc and chamfering segment edge where the cutting resistance is the largest While the negative chamfer increases the strength, it can effectively separate the chips, avoid chip deformation and extrusion, reduce the cutting temperature, and not damage the cutter head of the parts.

Abstract

Disclosed are a gear milling blade for forming a pivoting support gear profile and a method for manufacturing the pivoting support gear profile. According to the shape of the pivoting support gear type, a special-shaped tool structure is used, and each whole cutting edge is sectioned and shaped according to stress distribution of cutting force on the cutting edge in machining; a side edge of the blade is provided with a sharp cutting edge and properly protected in a rounded manner in order to reduce the cutting force; and formed arcs and chamfer edges with the maximum cutting resistance are provided with chamfers of special structures to enhance strength, cuttings can be effectively distributed and prevented from deformation and extrusion, cutting temperature is reduced, a part cutter is not damaged, cutting is stable, and the performance of the blade is obviously improved to reach that of imported products or exceed that of parts of the imported products.

Description

technical field [0001] The invention relates to a machining cutting tool, in particular to a high-efficiency forming milling blade for gear teeth of slewing bearings in wind power and general machinery industries and a manufacturing method thereof. Background technique [0002] Milling is a very common metal cutting process, which is currently divided into ordinary milling and high-speed milling; especially high-speed milling, due to the high metal removal rate, high processing accuracy and good processing surface Quality, therefore, is generally valued in modern manufacturing and has developed quite rapidly. Compared with the traditional cutting process, the cutting speed and feed rate in high-speed machining have been greatly improved, and the cutting mechanism is also different. With the continuous deepening of research on high-speed machining technology, especially driven by related technologies such as processing machine tools, numerical control systems, tool systems, ...
