The requirement of change increasingly come it is high, while mitigate mold deadweight, reduce mold changing labor intensity it is also most important, traditional Bending Mould one
As using steel make Bending Mould, its cost is high, and reason is big again, it has not been convenient to quick mold changing, meanwhile, processed to sheet metal
Cheng Zhong, easily produce impression and scratch because plate surface is rised sheer from level ground, it is difficult to meet the needs of production.
Utility model content
The purpose of this utility model is to overcome insufficient existing for existing Bending Mould, there is provided a kind of light no scar mould
Tool, realize that simple in construction, with short production cycle, manufacturing cost is low, standard interchangeability is high, the quick renewal for effectively adapting to product is changed
Generation, while improve the presentation quality of sheet metal product, increase economic efficiency and be easy to mold management and maintenance.
The technical scheme that the utility model solves technical problem is as follows：
A kind of light no scar Bending Mould of the utility model, including bending upper die and bending lower die, it is characterized in that：It is described
Bending lower die includes lower mould die ontology and at least one bending V grooves；The side position of notch two of the bending V grooves is respectively provided with circular arc
Groove；The hard alloy plug being adapted with the arc groove is provided with the arc groove；The bending upper die includes upper die mold
Body and the hard alloy mold insert for being arranged on upper die mold body lower end；The folding of the hard alloy mold insert profile and bending lower die
Curved V grooves match.
Further, the material of described upper die mold body and lower mould die ontology is high-strength aluminum alloy.
Further, the intensity of described high-strength aluminum alloy is more than 600N/mm2。
Further, the hardness of described hard alloy plug and hard alloy mold insert is in more than HRC60.
Further, the diameter of described hard alloy plug is more than the distance at each arc groove opening both ends.
Further, two faces that the arc surface of the hard alloy plug is connected with arc groove opening respectively are tangent.
During using the utility model, sheet metal is put on bending lower die, then by bending upper die to sheet metal
Carry out Bending Processing, sheet metal only hard alloy core rod touch with bending lower die, and hard closes in whole bending process
Golden plug can along sheet material moving direction rotate, make sheet metal with after bending lower die contact by traditional static friction
It is changed into present rolling friction, eliminates sheet metal surface due to being squeezed and caused impression and scratch, effectively increase
The presentation quality and precision of workpiece.The utility model, can be according to workpiece sheet material when carrying out Bending Processing to sheet metal
Material, thickness, bending angle and bending length select suitable die ontology section bar, hard alloy plug and hard alloy mold insert
It is assembled into required Bending Mould.
Relative to prior art, the utility model has advantages below：
(1) simple in construction, standardization interchangeability is high, workable；
(2) upper die mold body is made with lower mould die ontology using high-strength alloy, Bending Mould light unit weight
(the 1/3 of ≈ common dies), mold changing labor intensity is greatly reduced, improves operating efficiency；
(3) upper die mold body is made with lower mould die ontology using high-strength alloy, is processed suitable for standardization, is shortened
In the Mold Making cycle, die cost is reduced, precision is high, increases economic efficiency；
(4) hardness of hard alloy plug and hard alloy mold insert has high accuracy, anti abrasive spy in more than HRC60
Property, improve the precision and service life of mould；
(5) presentation quality and precision of improved sheet metal product.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in Figures 1 to 4, a kind of light no scar Bending Mould, including bending upper die and bending lower die, the bending
Lower mould includes lower mould die ontology 3 and at least one bending V grooves 5；The side position of notch two of the bending V grooves 5 is respectively provided with circular arc
Groove 6；The hard alloy plug 4 being adapted with the arc groove 6 is provided with the arc groove 6；The bending upper die includes upper mould
Die ontology 1 and the hard alloy mold insert 2 for being arranged on the lower end of upper die mold body 1；The profile of hard alloy mold insert 2 and bending
The bending V grooves 5 of lower mould match.
The material of described upper die mold body 1 and lower mould die ontology 3 is high-strength aluminum alloy.Here high intensity
Aluminium alloy refers to the superhard high strength alumin ium alloy using aluminium zinc-magnesium albronze as series, makes upper die mold body 1 and lower mould mould
During body 3, integral high-strength aluminum alloy die ontology section bar can be first produced according to design drawing, then carries out bending again
