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 a kind of mould wide-line processing special holder.
Background technology：
At present the cutter used in the processing of car large-scale covering mostly is to the mirror surface type rose cutter of single centre of sphere, this
Plant cutter and belong to a contact narrow row processing in process, cause working (machining) efficiency reduction, machined surface quality uncontrollable, and mesh
Knife bar used by front mold industry is also all to contact the mated knife bar of narrow row processing with this point, and knife bar used is in positioning mode
Above adopt one side positioning, the trip bolt that is connected by between knife bar and blade is connected more.For car panel die, its mould
Tool material mostly is the mould steel such as Cr12MoV and 7CrSiMnMoV, and after quenching, hardness reaches HRC50-65, belongs to typical case high
Intensity, high hardness material.Cutting vibration is obvious in process for this high hardness material, and cutting force is larger, rose cutter knife
Piece and knife bar are only passed through one side and are positioned with screw, in process, larger cutting vibration and cutting force, and lead to trip bolt normal
Occur loosening and disrepair phenomenon, lead to blade and knife bar connectivity poor, cause mould processing type face and scale error.
Content of the invention：
It is an object of the invention to provide a kind of mould wide-line processing special holder.
The object of the present invention is achieved like this：
A kind of mould wide-line processing special holder, its composition includes：Front knife bar, described front knife bar is connected with rear knife bar,
Described front knife bar has screw hole, and described front knife bar is fixedly connected by screw with cutter blade, and described front knife bar has
Curved groove A and curved groove B, after described curved groove A and cutter blade, knife face and cutter blade upper surface intersection coordinate, described
Curved groove B and cutter blade after knife face coordinate with cutter blade lower surface intersection；Described front knife bar is by rear knife face mating surface
Knife face cooperation after A and rear knife face mating surface B and described cutter blade, cutting edge groove is coordinated with cutter blade Circular Nose Cutting Edge and straight sword,
Rake face mating surface A and rake face mating surface B are coordinated with described cutter blade rake face；Described front knife bar passes through cooperation
Inclined-plane A and cooperation inclined-plane B is coordinated with described cutter blade intermediate incline, and knife bar cooperation inclined-plane A and cooperation inclined-plane B and cutter blade
Intermediate incline angle is consistent, limits axial rotation in knife bar during clamping for the blade, described front knife bar rake face mating surface A
Adopt transition circle cambered surface A with cooperation inclined-plane A transition portion, rake face mating surface B adopts transition with cooperation inclined-plane B transition portion
Arc surface B, described mould wide-line processing special holder blade outer surface mating surface A and the mould indexable bulb of wide-line processing
The upper surface cooperation of cutting plate for milling cutters, described mould wide-line processing special holder blade outer surface mating surface B and mould wide row
Process the lower surface cooperation of indexable rose cutter blade, described mould wide-line processing special holder has tangent plane A and tangent plane
B, described mould wide-line processing special holder has straight trough A and straight trough B, and described knife bar passes through on straight trough A and cutting plate for milling cutters
Surface and the cooperation of cooperation inclined-plane A intersection, described knife bar is passed through straight trough B and is intersected with cooperation inclined-plane B with cutting plate for milling cutters lower surface
Place's cooperation, described mould wide-line processing special holder has point of a knife groove A and point of a knife groove B, prevents from producing during blade positioning
Positioning, described rear knife bar is connected with machine tool chief axis handle of a knife system.
Beneficial effect：
1. provide mould wide-line processing indexable rose cutter special holder, and this knife bar is except adopting screw
Hole and one side positioning is outer, increased knife face mating surface after knife face and knife bar after cutter, cutting plate for milling cutters intermediate incline and knife bar cooperation
The positioning on inclined-plane, reduces the possibility of the screw loosening causing in mould processing due to cutting vibration and larger cutting force.
