Description

The mould structure that hot forming steel plate drift is lubricated
Technical field
The present invention relates to a kind of mould structure that hot forming steel plate drift is lubricated, especially one kind is for through overheated Shaping process after high intensity and the mould that is punched out of ultrahigh-strength steel plates, 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 punching technology of hot forming steel plate, because steel plate intensity itself and hardness are very high, drift abrasion is very tight Weight, finally produces punching burr, affects workpiece quality.For this reason, conventional method is the sintered steel using high rigidity, or even Increase the process for treating surface such as TD, PVD coating on the basis of sintered steel, the cost of cutting edge thus becomes very expensive.
Another solution is the lubricating condition of drift when improving punching, 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 punching technology quality and cost.
Content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, provides and a kind of hot forming steel plate drift is moistened Sliding mould structure, is not increasing on the premise of extra cost also do not lose production efficiency, effectively lubricating drift.
The technical scheme providing according to the present invention, the described mould structure that hot forming steel plate drift is lubricated, including Quiet separate insert and dynamic separate insert, in quiet separation, punching concave die set is arranged on insert, dynamic separate in insert setting drift and Binder block, drift is matched with punching concave die set;It is characterized in that:In the sheathed lubricating sleeve of the root of described drift, lubricating sleeve is circle Ring-type, has circular inner chamber inside lubricating sleeve, in some oil leaking holes of the inner surface setting of lubricating sleeve;The circle of described lubricating sleeve The inner chamber of ring-type is connected with lubrication source by lubricating oil pipeline.
Further, the installation site of described lubricating sleeve is located at drift in the region of upper end mounting seat 5 ~ 80mm.
Further, the material of described lubricating sleeve is plastics, resin, ferrum or copper.
Further, the described dynamic insert upper that separates connects fluid power system.
The present invention has following technique effect:(1)Oiling technique after the present invention can omit hot forming, before punching;(2) The present invention is especially suitable for the project that existing segregation apparatuss are improved, substantially do not need to do any changing to original segregation apparatuss Dynamic, the good pipeline connecting lubrication source of need only arranging, it is to avoid interfere with existing segregation apparatuss, change cost lower.
Brief description
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the I enlarged drawing of Fig. 1.
Fig. 3 is the sectional view of lubricating sleeve.
Specific embodiment
With reference to concrete accompanying drawing, the invention will be further described.
As shown in Fig. 1~Fig. 2:The described mould structure that hot forming steel plate drift is lubricated include quiet separate insert 1, Punching concave die set 2, drift 3, binder block 4, dynamic separation insert 5, fluid power system 6, workpiece 7, lubricating sleeve 8, oil leaking hole 9, profit Lube pipe 10, lubrication source 11 etc..
As shown in figure 1, the present invention includes the quiet insert 1 that separates separates insert 5 with dynamic, move and separate insert 5 top connection hydraulic pressure Drive system 6, separates setting punching concave die set 2 in insert 1 quiet, separates setting drift 3 and binder block 4 in insert 5, punching dynamic 3 are matched with punching concave die set 2;Root in described drift 3(I.e. close to the position of drift 3 mounting seat)Sheathed lubricating sleeve 8, The installation site of lubricating sleeve 8 is located at drift 3 in the region of upper end mounting seat 5 ~ 80mm;The material of described lubricating sleeve 8 is to mould Material or the organic composite material such as resin or be the metal material such as ferrum, copper, lubricating sleeve 8 is circular, has inside lubricating sleeve 8 Circular inner chamber, in some oil leaking holes of the inner surface setting of lubricating sleeve 89 it is ensured that lubricating oil is by lubricating sleeve 8 inner surface Oil leaking hole 9 flows out, and the circumferencial direction along drift 3 infiltrates drift 3;
The circular inner chamber of described lubricating sleeve 8 is connected with lubrication source 11 by lubricating oil pipeline 10.
The operation principle of the present invention:Before producing, lubricating oil pipeline 10 is connected with lubrication source 11, lubricating oil is delivered to lubrication In the inner chamber of set 8, then flowed out by the inwall of lubricating sleeve 8, the circumferencial direction along drift 3 infiltrates drift 3, finally in the effect of gravity Under, the working portion that infiltration drift is contacted with workpiece 7 foremost, thus complete the lubrication to drift cutting edge;Every time after punching press, Workpiece, quiet separation insert and its die case take away parts of lubricating oil, lubrication source sustainable supply lubricating oil, thus reaching lubrication output With the balance consuming.
