Description
Technical field
The present invention relates to a kind of inclined-plane lubricated dies structure reducing the wearing and tearing of hot forming steel plate trimming edge, especially a kind of mould for carrying out deburring 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 deburring technique of hot forming steel plate, due to the intensity of steel plate own and hardness very high, trimming edge 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 cutting edge when improving deburring, 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 deburring processing quality and cost.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of inclined-plane lubricated dies structure reducing the wearing and tearing of hot forming steel plate trimming edge is provided, do not increasing under the prerequisite that extra cost do not lose production efficiency yet, effectively lubricating trimming edge.
According to technical scheme provided by the invention, the inclined-plane lubricated dies structure of described reduction hot forming steel plate trimming edge wearing and tearing, comprise upper die and lower die seat, holding pad, patrix deburring insert and counterdie deburring insert, holding pad is arranged on patrix, and holding pad contacts with patrix deburring insert; It is characterized in that: the upper end of described patrix deburring insert is for installing bottom surface, the lower end of patrix deburring insert is trimming edge, between the installation bottom surface and trimming edge of patrix deburring insert, arrange oil groove, oil groove is arranged on the side that patrix deburring insert contacts with holding pad; Described oil groove comprises the first facade and the second facade, first facade is facade away from mold center and the first facade is crossing with the installation plane perpendicular of patrix deburring insert upper end, second facade be perpendicular to workpiece trimming edge face, be positioned at side near mold center, connected by fillet surface between the lower end of the first facade and the upper end of the second facade.
Further, the vertical range between the lower end of described first facade and the upper end of the second facade is 2 ~ 15mm.
Further, the angle between the trimming edge place horizontal plane of described fillet surface and patrix deburring insert is 0 ~ 65 °.
Further, described fillet surface is positioned at the middle part of the side that patrix deburring insert contacts with holding pad.
Further, the trimming edge 15 ~ 50mm of described fillet surface distance patrix deburring insert lower end.
Further, a fuel feed hole is set in the upper end of described patrix deburring insert, the lower end of fuel feed hole and the first facade chamfered transition.
The present invention has following technique effect: after (1) the present invention can omit hot forming, the oiling technique before deburring; (2), after the present invention needs to arrange oil circuit according to cutting edge lubrication in advance, it is convenient to implement, and can not produce additional workload in material cost, manufacturing complexity etc., not do significant impact to mould structure, die manufacturing cost does not change substantially.
