Description
Technical field
The present invention relates to a kind of mould structure lubricated hot forming steel plate drift, especially a kind of mould carrying out punching for 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 object of the invention is to overcome the deficiencies in the prior art, a kind of mould structure lubricated hot forming steel plate drift is provided, do not increasing under the prerequisite that extra cost do not lose production efficiency yet, effectively lubricating drift.
According to technical scheme provided by the invention, the described mould structure lubricated hot forming steel plate drift, comprises quiet separation insert and is separated insert with dynamic, quiet separation insert arranges punching concave die cover, dynamic separation insert arranges drift and binder block, and drift matches with punching concave die cover; It is characterized in that: at the sheathed lubricating sleeve of the root of described drift, lubricating sleeve is circular, and lubricating sleeve inside has circular inner chamber, arranges some oil leaking holes at the inner surface of lubricating sleeve; The torus shaped cavity of described lubricating sleeve is connected with lubrication source by lubricating oil/lubricating fluid pipeline.
Further, the installation site of described lubricating sleeve is positioned at the region of drift distance upper end mount pad 5 ~ 80mm.
Further, the material of described lubricating sleeve is plastics, resin, iron or copper.
Further, described dynamic separation insert upper connects fluid power system.
The present invention has following technique effect: after (1) the present invention can omit hot forming, the oiling technique before punching; (2) the present invention is specially adapted to the project improved existing separator, does not substantially need to do any change to original separator, the pipeline of connection lubrication source of need only having arranged, avoids interfering with existing separator, changes cost lower.

Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Fig. 1 ~ Fig. 2: as described in mould structure that hot forming steel plate drift is lubricated comprise quiet separation insert 1, punching concave die cover 2, drift 3, binder block 4, be dynamicly separated insert 5, fluid power system 6, workpiece 7, lubricating sleeve 8, oil leaking hole 9, lubricating oil/lubricating fluid pipeline 10, lubrication source 11 etc.
As shown in Figure 1, the present invention includes quiet separation insert 1 and be separated insert 5 with dynamic, dynamic insert 5 top that is separated connects fluid power system 6, and quiet separation insert 1 arranges punching concave die cover 2, dynamic separation insert 5 arranges drift 3 and binder block 4, and drift 3 and punching concave die are overlapped 2 and are matched; At root (namely close to the position of drift 3 mount pad) the sheathed lubricating sleeve 8 of described drift 3, the installation site of lubricating sleeve 8 is positioned at the region of drift 3 apart from upper end mount pad 5 ~ 80mm; The material of described lubricating sleeve 8 is the organic composite material such as plastics or resin or is the metal material such as iron, copper, lubricating sleeve 8 is circular, lubricating sleeve 8 inside has circular inner chamber, at the inner surface of lubricating sleeve 8, some oil leaking holes 9 are set, can ensure that lubricating oil/lubricating fluid is flowed out by the oil leaking hole 9 of lubricating sleeve 8 inner surface, and infiltrate drift 3 along the circumferencial direction of drift 3;
The torus shaped cavity of described lubricating sleeve 8 is connected with lubrication source 11 by lubricating oil/lubricating fluid pipeline 10.
Operation principle of the present invention: before producing, lubricating oil/lubricating fluid pipeline 10 is connected with lubrication source 11, lubricating oil/lubricating fluid is delivered in the inner chamber of lubricating sleeve 8, flowed out by the inwall of lubricating sleeve 8 again, circumferencial direction along drift 3 infiltrates drift 3, finally under gravity, infiltrate the working portion that drift contacts with workpiece 7 foremost, thus complete the lubrication to drift cutting edge; After each punching press, workpiece, quiet separation insert and die case thereof take away parts of lubricating oil/lubricating fluid, lubrication source sustainable supply lubricating oil/lubricating fluid, thus reach lubrication output and the balance consumed.
