Abstract

The invention relates to an indexable ball end mill for molds. In the working process of high-hardness materials, the cutter is severely abraded and damaged; and since the mirror-face ball end mill used in the existing plant is non-indexing, after one blade loses effect, part of the ball end mill needs to be reground, and the rest of the ball end mill completely loses effect and can not continue in service, thereby lowering the production efficiency and increasing the use cost of the cutter. The ball end mill comprises a cutter holder (24), wherein a blade upper surface (5) is matched with a blade external surface matching surface A (29), a blade lower surface (19) is matched with a blade external surface matching surface B (32), the middle of the cutter holder is provided with a fastening screw hole, and the blade is connected with the cutter holder through a fastening screw (25). The indexable ball end mill for molds is used for cutters in the field of machining.

Description

The indexable rose cutter of mould
technical field:
the present invention relates to the indexable rose cutter of a kind of mould.
background technology:
automobile large-scale covering mould has that physical dimension is large, complex-shaped, dimensional accuracy and surface accuracy require high feature.Its mold materials mostly is the mould steel such as Cr12MoV and 7CrSiMnMoV, after quenching, hardness reaches HRC50-65, belongs to typical high strength, high hardness material, and this high hardness material is in process, the wearing and tearing of cutter and damaged situation are very serious, the minute surface rose cutter using in factory is at present non-transposition, and after a blades fail, a part is used after need to refacing, a part is entirely ineffective, can not continue to use, reduce production efficiency, increase the use cost of cutter.And because place, rose cutter summit in the past linear velocity is zero, work in-process point of a knife place easily produces wearing and tearing, even produces tipping.Especially when processing automobile mould median-plane location, this because point of a knife linear velocity is that the zero machined surface quality variation causing, cutter life situation about reducing is particularly serious.
summary of the invention:
the object of the present invention is to provide the indexable rose cutter of a kind of mould.
the object of the present invention is achieved like this:
the indexable rose cutter of a kind of mould, its composition comprises: knife bar, blade upper surface coordinates with blade outer surface mating surface A, blade lower surface coordinates with blade outer surface mating surface B, after blade Circular Nose Cutting Edge, knife face coordinates with knife face mating surface B after knife face mating surface A and Circular Nose Cutting Edge after Circular Nose Cutting Edge, blade bevel coordinates with coordinating inclined-plane A and cooperation inclined-plane B, and described knife bar middle has trip bolt hole, and described blade is connected with described knife bar by trip bolt.
the indexable rose cutter of described mould, described blade has four arc edges and four straight swords, the rake face A that is respectively arc edge A and is adjacent, rear knife face A, straight sword A, arc edge B and the rake face B being adjacent, rear knife face B, straight sword B, arc edge C and the rake face C being adjacent, rear knife face C, straight sword C, arc edge D and the rake face D being adjacent, rear knife face D, straight sword D, after Circular Nose Cutting Edge knife face respectively with the Circular Nose Cutting Edge of knife bar after knife face mating surface A, after Circular Nose Cutting Edge, knife face mating surface B coordinates, after straight sword knife face respectively with the straight sword of knife bar after knife face mating surface A, after straight sword, knife face mating surface B coordinates, blade upper surface and rake face C transition portion are inclined-plane C, inclined-plane C coordinates with the inclined-plane B that coordinates of knife bar, blade lower surface and rake face B transition portion are inclined-plane B, inclined-plane B coordinates with the inclined-plane A that coordinates of knife bar, two of knife bars coordinate inclined-plane to prevent from producing axial rotation in cutter blade clamping, blade upper surface and rake face A transition portion are inclined-plane A, blade lower surface and rake face D transition portion are inclined-plane D.
the indexable rose cutter of described mould, mould all adopts blunt circle to process with the Circular Nose Cutting Edge described in each and the straight sword described in each in indexable rose cutter cutting edge.
beneficial effect:
1. the present invention has 4 cutting edges, compares with 2 cutting edges of current used minute surface rose cutter, and cutting edge quantity is the twice of the current ball head knife using, and doubled the service life of cutter, and working (machining) efficiency and cost have obtained and increased exponentially.
2. ball head knife cutting edge Front-end Design of the present invention has straight sword, makes in process because place, ball head knife summit speed is that zero corner wear, the damaging problem causing and the crudy variation problem causing thus improve.
