Description
Technical field
The present invention relates to a kind of mould structure of lubrication hot forming steel plate trimming edge, especially one kind is for through overheated
Shaping process after high intensity and ultrahigh-strength steel plates carry out the mould of deburring, belong to the separation technology field of hot forming steel plate.
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 the effective means simultaneously guaranteeing 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
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 quenching two stages of cooling, wherein, shaping stage needs once stamping by mould at high temperature, quenching
Cooling stage needs to cool down rapidly by controlling certain rate of cooling, so that steel plate occurs from austenite microstructure to horse
The transformation of family name's body microstructure, thus obtains high intensity and hardness, taking common boron steel as a example, its intensity after hot forming process
Reach 1500MPa.The tensile strength of general high-strength steel sheet is in 400MPa～450MPa, and hot forming steel add
Before heat, tensile strength has reached 500 MPa～800MPa, then can 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 pottery, but has the toughness of steel, with common hot forming boron steel
As a example steel plate, intensity reaches 1500MPa, and elongation percentage is 5% about, and considerably beyond the high-strength steel of general significance, it 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, because 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 reason, conventional method is the sintered steel using high rigidity,
On the basis of sintered steel, even increase the process for treating surface such as TD, PVD coating, the cost of cutting edge thus becomes to hold high very much
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）Considering from the safety inventory producing, being often required to standby storehouse, even if ensure that advanced elder generation
The logistics principle going out, also usually appearance production is long for interval time, and covering lubricating oil/lubricating fluid on workpiece volatilizees, water clock,
Cause entirety or certain regional area lack of lubrication even without lubrication.
If it is possible to a kind of invention lubrication operation, both workpiece can be lubricated, and not increase production process,
Also ensure that the uniform, stable of lubrication, will have very big using value to the lifting of hot forming edge-neatening craftwork quality and cost.
Content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, provides a kind of lubrication hot forming steel plate trimming edge
Mould structure, do not increasing on the premise of extra cost also do not lose production efficiency, effectively lubricating trimming edge.
According to the present invention provide technical scheme, the mould structure of described lubrication hot forming steel plate trimming edge, including on
Mould, die shoe, holding pad, the upper die repair insert in insert and lower die repair, holding pad is arranged on mould, holding pad and upper die repair
Side insert contact；It is characterized in that：The upper end of described upper die repair side insert is to install bottom surface, and the lower end of upper die repair side insert is deburring
Cutting edge, is evenly arranged multiple oil grooves straight down in installing of upper die repair side insert between bottom surface and trimming edge, oil groove sets
It is placed on the one side that die repair side insert is contacted with holding pad；The upper end of described oil groove extends to die repair side insert upper end
Bottom surface, arc transition between the side of the lower end of oil groove and upper die repair side insert are installed.
Further, the bottom of described oil groove is apart from the trimming edge 0～15mm of upper die repair side insert lower end.
The present invention has following technique effect：（1）Oiling technique after the present invention can omit hot forming, before deburring；（2）
Although present invention processing oil groove is more, it is particularly suited for the project that existing mould is improved, one-tenth present aspect only need to be former
There is insert correspondence position to add oil groove, change cost lower.
