Description
Technical field
The utility model relates to a kind of for reducing hot forming steel plate drift dull die structure, and especially a kind of mould for carrying out punching to the high strength after hot forming process and ultrahigh-strength steel plates, belongs to the separation technology field of hot forming steel plate.
Background technology
High-strength steel sheet intensity is high, particularly there is higher comprehensive mechanical property in normalizing or normalizing tempered condition, the application of high-strength steel sheet is the effective means simultaneously guaranteeing lightweight and crashworthiness, is therefore widely used in the construction industry fields such as large ship, bridge, power station equipment, middle high-pressure boiler, high-pressure bottle, rolling stock, hoisting machinery.And hot forming steel plate is as a kind of Newly Sprouted Things, its production technology is different from common high-strength steel sheet, the production technology of hot forming steel plate generally includes shaping and two stages of quench cooled, wherein, shaping stage needs at high temperature once stamping by mould, quench cooled stage needs cool rapidly by controlling certain cooling velocity, thus steel plate is occurred from austenite microstructure to the transformation of martensite microstructure, obtain high intensity and hardness thus, for common boron steel, after hot forming process, its intensity reaches about 1500Mpa.The tensile strength of general high-strength steel sheet is at about 400MPa ~ 450MPa, and namely tensile strength reached 500 MPa ~ 800MPa before hot forming heat steel, heating then can be increased to 1300 ~ 1600 MPa after being shaped, its intensity is 3 ~ 4 times of rolled products of ordinary high-strength steel, its hardness is only second to pottery, but there is the toughness of steel, for common hot forming boron steel steel plate, intensity reaches 1500MPa, percentage elongation is about 5%, considerably beyond the high-strength steel of general significance, its separating technology difficulty is far away higher than general steel plate and common high-strength steel steel plate.
For the punching technology of hot forming steel plate, due to the intensity of steel plate own and hardness very high, drift wearing and tearing are very serious, finally produce punching burr, affect workpiece quality.For this reason, conventional method is the sintered steel using high rigidity, and even on the basis of sintered steel, increase the process for treating surface such as TD, PVD coating, the cost of cutting edge becomes very expensive thus.
Another solution is the lubricating condition of drift when improving punching, common method be after part hot forming through oiling technique, allow piece surface cover lubricating oil or lubricating fluid.But in batch production process: (1) increases by a sequence oiling technique, adds production cost; (2) consider from the safety inventory produced, usually for storehouse, even if ensure that the logistics principle of first in first out, also to usually occur producing interval time long, cover the lubricating oil/lubricating fluid volatilization above workpiece, water clock, cause entirety or certain regional area lack of lubrication even not to lubricate.
Therefore, if a kind of lubrication operation can be invented, both can lubricate workpiece, not increase production process again, the even, stable of lubrication can also be ensured, have very large using value by the lifting of hot forming punching technology quality and cost.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of for reducing hot forming steel plate drift dull die structure, do not increasing under the prerequisite that extra cost do not lose production efficiency yet, effectively lubricating drift.
According to the technical scheme that the utility model provides, described for reducing hot forming steel plate drift dull die structure, comprise upper die and lower die seat, patrix is arranged holding pad and patrix drift, die shoe is arranged counterdie punching die case, patrix drift and counterdie punching die case match; It is characterized in that: winding screw shape lubrication wire on described patrix drift, this lubrication wire is solid shape wire, and material adopts swab stick or toughened filter paper; Be equipped with lubricating oil/lubricating fluid pipeline in each first side of the upper punch of lubrication that needs, one end of lubricating oil/lubricating fluid pipeline is fixed on the floor installation face of patrix drift upper end, and the other end of lubricating oil/lubricating fluid pipeline is fixed on patrix; All lubricating oil/lubricating fluid pipeline converges forms main line, and main line is connected with lubrication source; One end of described lubricating oil/lubricating fluid pipeline adopts clamp connection with one end of lubrication wire, and the other end lubricating wire twines along the circumferencial direction of patrix drift and is attached on patrix drift.
Further, described lubrication wire is not less than a girth along the circumferencial direction winding of patrix drift.
Further, described lubrication wire is wrapped in the upper end of patrix drift, and the installation site of lubrication wire is positioned at patrix drift distance 5 ~ 80mm region, floor installation face, upper end.
Further, described lubricating oil/lubricating fluid pipeline arranges flow control valve.
The utility model has following technique effect: after (1) the utility model can omit hot forming, the oiling technique before punching; (2) the utility model is specially adapted to the project improved existing mould, does not substantially need to do any change to original mould structure, the pipeline of connection lubrication source of need only having arranged, avoids and existing mold constructive interference, changes cost lower; (3) the utility model needs the lubrication amount regulating each punching press, steady quality according to cutting edge lubrication.
