Manufacturing method for grooved vertical milling blade

Abstract

The invention discloses a manufacturing method for a grooved vertical milling blade, belongs to the technical field of machining, and aims to solve the problems of a non-standard blade hole pattern, high machining difficulty and low product percent of pass when the vertical milling blade is machined in the prior art. Groove profiles of a blade are designed on the two sides of a die, and the groove profiles are controlled by the stroke of a bidirectional press in combination with an inclined block and a reset spring to achieve entering and exiting of the groove profiles. In this way, one-time forming of a groove type and a hole type can be achieved on a common two-way press, and the manufacturing cost is greatly reduced. According to the technology, the influence of the core rod on powder filling is avoided, meanwhile, due to the fact that additional short-distance movement is added to the forming groove part, the density of the cutting edge part can be improved, the pressed blank is small in deformation, and the cutting edge quality is high. The manufacturing method is suitable for the vertical milling cutter blade with the groove.

Description

technical field [0001] The invention belongs to the technical field of machining, and in particular relates to a method for manufacturing vertically mounted milling inserts with grooves. Background technique [0002] With the development of mechanical processing, the requirements for cutting tools are getting higher and higher. Vertically mounted blades with grooves, good installation rigidity, and stable cutting are the development direction of modern processing. [0003] The feature of the slotted vertical blade is that the blade mounting hole and the cutting edge are not on the same plane, so it cannot be formed at one time on an ordinary two-way press. The current usual practice is to: [0004] 1. On the electric press with side pressure function, use a high-precision mold with side core pulling to realize one-time compression molding of the blank. The disadvantage of this method is that the requirements for the press and the mold are very high. Since the lateral mandr...
