Description
Technical field
The utility model relates to a kind of separator that can reduce hot forming steel plate punching wearing and tearing, 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 separator that can reduce hot forming steel plate punching wearing and tearing, 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, the described separator that can reduce hot forming steel plate punching wearing and tearing, comprise quiet separation insert and be separated insert with dynamic, quiet separation insert arranges punching concave die cover, the dynamic insert that is separated is positioned at above quiet separation insert, and dynamic separation in insert arranges binder block and drift; It is characterized in that: on described binder block, arrange through hole, through hole is formed by connecting by the identical first paragraph through hole of diameter and second segment through hole, and first paragraph through hole is positioned at second segment through hole top; Described drift is through through hole, and drift coordinates with via clearance, arranges internal thread at the inner surface of second segment through hole.
Further, the distance between described drift and through hole is 0.2 ~ 0.8mm.
Further, described internal thread adopts coarse thread.
Further, the inner surface of described first paragraph through hole is smooth surface.
The utility model has following technique effect: after (1) the utility model can omit hot forming, the oiling technique before punching; (2) oil groove is arranged on holding pad by the utility model, because holding pad is relatively independent, has designed rear concentrated processing, and manufacturing process is more effectively simple; (3) oil groove is arranged on holding pad by the utility model, and because holding pad is generally foundry goods or Fine Steel Casting iron, hardness is far below cutting edge insert (calculate with HRC, usual difference of hardness is not less than 20 degree), and processing is more efficient, convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the I enlarged drawing of Fig. 1.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1 ~ Fig. 2: as described in comprise quiet separation insert 1, punching concave die cover 2, drift 3, binder block 4 for the separator reducing hot forming steel plate punching wearing and tearing, dynamic be separated insert 5, fluid power system 6, workpiece 7, through hole 8, internal thread 9 etc.
As shown in Figure 1 and Figure 2, the utility model comprises quiet separation insert 1 and is separated insert 5 with dynamic, dynamic insert 5 top that is separated connects fluid power system 6, quiet separation insert 1 is arranged punching concave die cover 2, the dynamic insert 5 that is separated is positioned at above quiet separation insert 1, and dynamic separation in insert 5 arranges binder block 4 and drift 3; Described binder block 4 arranges through hole 8, and through hole 8 is formed by connecting by the identical first paragraph through hole of diameter and second segment through hole, and first paragraph through hole is positioned at second segment through hole top; Described drift 3 passes through hole 8, drift 3 and through hole 8 matched in clearance, and the distance between drift 3 and through hole 8 is 0.2 ~ 0.8mm; Arrange internal thread 9 at the inner surface of described second segment through hole, internal thread 9 is coarse thread preferably; The inner surface of described first paragraph through hole is smooth surface.
Operation principle of the present utility model: produce before by lubricating oil/lubricating fluid by Pipeline transport in through hole 8, and control flow, under gravity, along the surface of the internal thread 9 of second segment through hole, finally be covered with the outline line of this binder plate hole, thus complete the lubrication to punching; After each punching press, parts of lubricating oil/lubricating fluid taken away by workpiece 7, lubrication source sustainable supply lubricating oil/lubricating fluid, thus reaches lubrication output and the balance consumed.
