Abstract

The utility model discloses a PCD cutter for high brightness, comprising a carbide cutting rod and a PCD tip welded on the head end of the carbide cutting rod, the PCD tip is provided with an upper rake face and a lateral flank, the joining point of the rake face and the flank is provided with a cutting edge, wherein a main sleeking edge and an assist sleeking edge are arranged between the cutting edge and the rake face in order, the angle between the main sleeking edge and the assist sleeking edge is between -2 and 1 degree, the width of the miner first flank is from 0.02 to 0.15 mm, the angle between the assist sleeking edge and the rake face is between 15 to 25 degree, the width of the miner first flank is from 0.01 to 0.15mm, the utility model can turn out the qualified high brightness through two extrusions and produce the high brightness which traditional cemented carbides and ordinary PCD aluminium alloy cutters can not reach, which shortens the processing line and improve the producing efficiency and the surface roughness is lower than 32 micrometers.

Description

High brightness processing PCD cutter

Technical field:

The utility model relates to a kind of process tool of aluminium alloy decorative cover, the PCD cutter that particularly a kind of brightness processing request is high.

Background technology:

The processing of conventional aluminum alloy is to use hard alloy cutter to process, be all not ideal enough from surface roughness or brightness and service life, production efficiency, middle nineteen nineties is brought into use the processing of PCD (glomerocryst diamond) cutter, durability, roughness and the production efficiency of processing Al alloy parts improve greatly, but workpiece can produce piebald in the process of turning, and impurely in the Al alloy parts can produce pin hole more for a long time, these all can influence the brightness of machined surface greatly; The product that some outward appearance brightness is had relatively high expectations, as: the processing of car, electric motor car, motorcycle, beach buggy high brightness aluminum wheel hub; The aluminum substrate processing of hard grinding wheel; Natural gas gas-cooker high brightness cast aluminium kitchen range processing etc. all will have good smoothing effect.Notification number is that the Chinese patent of CN2761321Y discloses a kind of " turning insert of band wiper edges ", position in the major-minor drift angle is provided with wiper edges, played certain smoothing effect, but because the position of alloy cutter hub that this scheme adopts and wiper edges is provided with the brightness effect that all limits its processing work.

The utility model content:

Technical problem to be solved in the utility model is exactly to provide a kind of high brightness processing PCD lathe tool at the workpiece processing that aluminium alloy decorative cover brightness is had relatively high expectations, this lathe tool can process traditional carbide alloy and the general inaccessible brightness of PCD aluminium alloy cutter, shorten process route, and improved production efficiency.

Technical solution adopted in the utility model is:

A kind of high brightness processing PCD cutter, comprise carbide alloy knife bar and the PCD cutter head that is welded on the carbide cutter tool rod head end, the PCD cutter head has the rake face on top and the back knife face of sidepiece, rake face has cutting edge with knife face junction, back, wherein, set gradually main wiper edges and secondary wiper edges between cutting edge and the rake face.

Described main wiper edges is-2 °～1 ° angle with the back knife face.

The margin width of described main wiper edges is 0.02～0.15 millimeter.

Described secondary wiper edges and rake face are 15 °～25 ° angle.

The margin width of described secondary wiper edges is 0.01～0.15 millimeter.

Described cutting edge is 3 °～8 ° angle with the back knife face.

The technique effect that the utility model can reach is: the utility model goes out satisfactory high brightness by twice extruding, one train, can process traditional carbide alloy and the general inaccessible brightness of PCD aluminium alloy cutter, shortened process route and improved production efficiency, surface roughness is lower than 32 microns.

Fig. 3 looks enlarged drawing for the left side of Fig. 1.

The specific embodiment:

Further describe below in conjunction with 1,2,3 pairs of the utility model of accompanying drawing:

Embodiment 1: this high brightness processing PCD cutter, constitute by carbide alloy knife bar 10 and the PCD cutter head 20 that is welded on carbide alloy knife bar 10 head ends, has knife face 25 behind top rake face 21 and the sidepiece on the PCD cutter head 20, rake face 21 has cutting edge 24 with knife face 25 junctions, back, sets gradually main wiper edges 23 and secondary wiper edges 22 between cutting edge 24 and the rake face 21.Wherein main wiper edges 23 is-2 ° angle with back knife face 25, and margin width is 0.1 millimeter; Secondary wiper edges 22 is 20 ° angle with rake face, and margin width is 0.05 millimeter; Cutting edge 24 is 3 ° with the angle of back knife face 25.

Embodiment 2: the structure that the PCD cutter is used in this high brightness processing is with embodiment 1, and wherein main wiper edges 23 is 0 ° angle with back knife face 25, and margin width is 0.15 millimeter; Secondary wiper edges 22 is 15 ° angle with rake face 21, and margin width is 0.1 millimeter; Cutting edge 24 is 5 ° with the angle of back knife face 25.

Embodiment 3: the structure that the PCD cutter is used in this high brightness processing is with embodiment 1, and wherein main wiper edges 23 is 0.5 ° angle with back knife face 25, and margin width is 0.12 millimeter; Secondary wiper edges 22 is 25 ° angle with rake face 21, and margin width is 0.15 millimeter; Cutting edge 24 is 8 ° with the angle of back knife face 25.
