Abstract
The invention relates to a special cutter bar for wide-line processing of a mold. Most cutter bars used in the current mold industry are matched with point-contact narrow-line processing cutting tools, adopt a single-surface positioning mode and are connected with blades by fastening screws, the connection between the cutter bars and the blades is poor, and the phenomena of looseness and damage of the screws occur frequently. The special cutter bar comprises a front cutter bar (21) which is connected with a rear cutter bar (22), is provided with a screw hole (9) and is fixedly connected with a milling insert (24) through a screw (23). The special cutter bar is used for wide-line processing of the mold.
Description
technical field:
the present invention relates to the wide row processing of a kind of mould special holder.
background technology:
for the cutter using in the processing of car large-scale covering, mostly be at present the mirror surface type rose cutter of single centre of sphere, this cutter belongs to a contact narrow row processing in process, cause that working (machining) efficiency reduces, machined surface quality is uncontrollable, and die industry knife bar used is all also the knife bar that contacts narrow row machining coupling with this point at present, knife bar used is the one side location that adopt in locate mode more, and knife bar connects with the employing trip bolt that is connected between blade.For car panel die, its mold materials mostly is the mould steel such as Cr12MoV and 7CrSiMnMoV, and after quenching, hardness reaches HRC50-65, belongs to typical high strength, high hardness material.The cutting vibration in process of this high hardness material is obvious, cutting force is larger, rose cutter blade and knife bar are only located by one side and screw, in process, larger cutting vibration and cutting force, cause the normal appearance of trip bolt to be become flexible and disrepair phenomenon, cause blade and knife bar connectivity poor, cause Mould Machining profile and scale error.
summary of the invention:
the object of the present invention is to provide the wide row processing of a kind of mould special holder.
the object of the present invention is achieved like this:
the wide row processing of a mould special holder, its composition comprises: front knife bar, described front knife bar is connected with rear knife bar, and described front knife bar has screw hole, and described front knife bar is fixedly connected with by screw with cutter blade.
the wide row processing of described mould special holder, described front knife bar has curved groove A, curved groove B, and described curved groove A, described curved groove B coordinate with the upper and lower surperficial intersection of knife face after cutter blade and cutter blade respectively, described front knife bar coordinates with knife face after described cutter blade by rear knife face mating surface A, rear knife face mating surface B, and cutting edge groove coordinates with cutter blade Circular Nose Cutting Edge, straight sword, and rake face mating surface A and rake face mating surface B coordinate with described cutter blade rake face, described front knife bar is by coordinating inclined-plane A and coordinating inclined-plane B to coordinate with described cutter blade transition inclined-plane, and knife bar coordinates inclined-plane consistent with cutter blade transition bevel angle, limited blade axial rotation during clamping in knife bar, described front knife bar rake face mating surface A adopts transition circle cambered surface A with coordinating inclined-plane A transition portion, rake face mating surface B adopts transition circle cambered surface A with coordinating inclined-plane B transition portion, the wide row processing of described mould special holder blade outer surface mating surface A, blade outer surface mating surface B processes the upper of indexable rose cutter blade with mould with wide row respectively, lower surface coordinates, the wide row processing of described mould special holder has tangent plane A and tangent plane B, the wide row processing of described mould special holder has straight trough A and straight trough B, described knife bar is by straight trough and cutting plate for milling cutters, lower surface coordinates with intersection, inclined-plane, the wide row processing of described mould special holder has point of a knife groove A and point of a knife groove B, while preventing blade location, produced location.
the wide row processing of described mould special holder, described rear knife bar is connected with machine tool chief axis handle of a knife system.
beneficial effect:
1. provide mould to process indexable rose cutter special holder with wide row, and this knife bar is except adopting screw hole and one side location, increase knife face after cutter and coordinated the location on inclined-plane with knife face mating surface, cutting plate for milling cutters transition inclined-plane and knife bar after knife bar, reduced in Mould Machining the possibility due to cutting vibration and the screw loosening that causes compared with large cutting force.
