Description
Technical field
The present invention relates to a kind of inclined-plane lubricated dies structure for reducing the abrasion of hot forming steel plate trimming edge, especially a kind of
For the mould of deburring is carried out to the high intensity and ultrahigh-strength steel plates after hot forming is processed, belong to dividing for hot forming steel plate
From technical field.
Background technology
High-strength steel sheet intensity is high, particularly has higher comprehensive mechanical property in normalizing or normalizing tempered condition, high
The application of strength steel sheet is while guarantee the effective means of lightweight and crashworthiness, therefore in large ship, bridge, power station
It is widely used in the construction industry fields such as equipment, middle high-pressure boiler, high-pressure bottle, rolling stock, hoisting machinery.And hot forming
Used as a kind of Newly Sprouted Things, its production technology is different from common high-strength steel sheet to steel plate, and the production technology of hot forming steel plate is led to
Often include shaping and quench two stages of cooling, wherein, shaping stage needs once stamping by mould at high temperature, quenching
Cooling stage needs to be cooled down by controlling certain rate of cooling rapidly, so that steel plate occurs from austenite microstructure to horse
The transformation of family name's body microstructure, thus obtains high intensity and hardness, by taking common boron steel as an example, its intensity after hot forming process
Reach 1500MPa or so.The tensile strength of general high-strength steel sheet is in 400MPa～450MPa or so, and hot forming steel add
Before hot, tensile strength has reached 500 MPa～800MPa, can then improve to 1300～1600 MPa, its intensity after thermoforming
For 3～4 times of rolled products of ordinary high-strength steel, its hardness is only second to ceramics, but the toughness with steel, with common hot forming boron steel
As a example by steel plate, intensity reaches 1500MPa, and elongation percentage is 5% or so, and considerably beyond the high-strength steel of general significance, which separates work
Skill difficulty is significantly larger than general steel plate and common high-strength steel steel plate.
For the edge-neatening craftwork of hot forming steel plate, as steel plate intensity itself and hardness are very high, trimming edge abrasion is non-
Chang Yanchong, finally produces punching burr, affects workpiece quality.For this purpose, conventional method is the sintered steel using high rigidity,
Even increase the process for treating surface such as TD, PVD coating on the basis of sintered steel, thus the cost of cutting edge becomes to hold high very much
It is expensive.
Another solution is the lubricating condition of cutting edge when improving deburring, and common method is in part hot forming
Later through oiling technique, piece surface is allowed to cover lubricating oil or lubricating fluid.But in batch production process：（1）Increase by one
Sequence oiling technique, increased production cost；（2）Consider from the safety inventory of production, be often required to standby storehouse, even if ensure that advanced elder generation
The logistics principle for going out, also usually appearance production is interval time long, and the lubricating oil/lubricating fluid being covered in above workpiece volatilizees, water clock,
Entirety or certain regional area lack of lubrication are caused even without lubrication.
If it is possible to invent a kind of lubrication operation, both workpiece can be lubricated, and not increase production process,
The uniform, stable of lubrication is also ensured that, the lifting to hot forming edge-neatening craftwork quality and cost is had into very big using value.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided a kind of to reduce hot forming steel plate trimming edge
The inclined-plane lubricated dies structure of abrasion, is not increasing on the premise of extra cost also do not lose production efficiency, effectively lubricating deburring
Cutting edge.
According to the technical scheme that the present invention is provided, the inclined-plane lubricated dies of the reduction hot forming steel plate trimming edge abrasion
Structure, including upper die and lower die seat, holding pad, the upper die repair insert in insert and lower die repair, holding pad are arranged on mould, pressure
Flitch and the contact of upper die repair side insert；It is characterized in that：The upper end of the upper die repair side insert is installation bottom surface, upper die repair side insert
Lower end be trimming edge, between the installation bottom surface of upper die repair side insert and trimming edge, oil groove is set, oil groove is arranged at
On the one side that die repair side insert is contacted with holding pad；The oil groove includes the first facade and the second facade, and the first facade is remote
Facade and the first facade from mold center is intersected with the installation plane perpendicular of upper die repair side insert upper end, and the second facade is
Perpendicular to the trimming edge face of workpiece, positioned near the upper end of the side of mold center, the lower end of the first facade and the second facade
Between by fillet surface connect.
Further, the vertical dimension between the lower end of first facade and the upper end of the second facade is 2～15mm.
Further, the angle between the trimming edge place horizontal plane of the fillet surface and upper die repair side insert be 0～
65°。
Further, the fillet surface is located at the middle part of the one side that upper die repair side insert is contacted with holding pad.
Further, trimming edge 15～50mm of the fillet surface apart from upper die repair side insert lower end.
Further, the upper end of die repair side insert arranges a fuel feed hole on described, and the lower end of fuel feed hole is stood with first
Face chamfered transition.
The present invention has following technique effect：（1）Oiling technique after the present invention can omit hot forming, before deburring；（2）
The present invention needs to arrange after oil circuit according to cutting edge lubrication in advance, easy to implement, will not at aspects such as material cost, manufacturing complexity
Additional workload is produced, significant impact is not done to mould structure, die manufacturing cost is not changed in substantially.
