Abstract
The utility model belongs to the technical field of forming moulds for super-high strength steel plates and relates to a second-stage drawing forming mould for drawing the double-cap shape of a super-high strength steel plate car door anti-collision beam. The drawing forming mould comprises an upper mould and a lower mould. The lower mould is characterized in that a movable and slim pressing core is installed in the center of a casting lower mould holder, a nitrogen cylinder used for driving the pressing core to move upwards is arranged on the lower side of the pressing core, and female mould inserts are installed on two sides of the pressing core and between retaining walls. The upper mould is characterized in that a male mould insert is arranged in the middle of an upper mould holder. When the mould is closed, two ends of the pressing core is in guide sliding with the lower mould holder through a guide plate, a material-thickness gap is maintained between the female mould inserts of the upper mould and the male mould insert of the lower mould and between the female mould inserts of the upper mould and the pressing core, and the insertion-type guide plate fixed on the upper mould holder is inserted into a guide groove in the lower mould holder to guide the upper mould and the lower mould. The drawing forming mould has the advantages that the structure is compact, cutting block supporting is firm and reliable, resilience adjustment is convenient and fast, and upward drawing work for the double-cap shape of the car door anti-collision beam can be well completed.
Description
Technical field
The utility model belongs to the mould technical field, refers in particular to the second order drawing and moulding mould that a kind of ultrahigh-strength steel plates door anti-collision joist draws two cap shaped.
Background technology
Door anti-collision joist is the web beam that is contained in the car door internal structure, and in order to strengthen the structure of vehicular sideview, when side collision took place, door anti-collision joist absorbed collision energy by producing distortion, reduces the purpose that the occupant comes to harm thereby reach.
At the beginning of last century, mid-term, automobile body covering piece all is to adopt the carbon element mild steel plate to be stamped to form, its tensile strength is about 340MPa, about 30～40 ﹪ of percentage elongation, deep punching steel can reach more than 50 ﹪, forming property is splendid, the requirement to steel plate was forming property at that time.To the sixties in last century, the passive safety of automobile becomes the hot issue of concern, countries in the world promulgated in succession just comprising, side collision, the automotive safety rules of regulations such as top cover collision and rolling, therefore the requirement to steel plate is then required to forward on the requirement of strength by plasticity, and the various high-strength steel sheets that continue arise at the historic moment, studies show that car weight 10 ﹪ that descend, 7～8 ﹪ fall in oil consumption, and 4 ﹪ fall in blowdown, and this meets environmental protection requirement very much.Described high-strength plate comprises that namely yield strength is greater than the common high-strength plate of 210MPa, yield strength is also arranged greater than the strong plate of superelevation of 550MPa with greater than the strong plate of extra-high-speed of 1000～1600MPa, ultrahigh-strength steel plates is the new material that is adopted in a large number the nearly more than ten years, its tensile strength is 4～5 times of normal carbon mild steel, percentage elongation only is about 20 ﹪ of mild steel, distortion difficulty and resilience are very big, and especially distortion resilience in plane is very difficult to repair, and uses conventional process for stamping and experience and loses efficacy substantially.
Summary of the invention
The purpose of this utility model provides a kind of ultrahigh-strength steel plates door anti-collision joist drawing and moulding mould.
The purpose of this utility model is achieved in that
Ultrahigh-strength steel plates door anti-collision joist drawing and moulding mould, include patrix and counterdie, described counterdie is: the center of casting die shoe is equipped with movable and elongated binder core, be provided with below the binder core and drive the nitrogen cylinder that moves on the binder core, the both sides of binder core, die plate insert is installed in the middle of the barricade, described patrix is: be provided with punch insert on the upper bolster between two parties, when mould is closed, the two ends of binder core guide plate and die shoe slide guide, the punch insert of patrix and the die plate insert of counterdie and binder core keep a material thick clearance, are fixed on plug-in type guide plate on the upper bolster and insert in the guide groove of people's die shoe and lead for upper and lower mould.
Be provided with cushion block between above-mentioned nitrogen cylinder and the binder core, the downside of nitrogen cylinder is provided with backing plate.
Above-mentioned binder core binder core, punch insert and die plate insert adopt the manufacturing of SKD11 material, carry out 60HRC quenching and TD processing.
The bearing pressure of above-mentioned patrix and counterdie is more than the 1400T.
The utility model outstanding and beneficial technical effects compared to existing technology is:
1, the utility model adopts the two shape for hat collision prevention girders of drawing die moulding, has not only reduced resilience, has improved quality, and is shaped with launching part, after the shaping without deburring, can meticulous stock layout, prepare the expansion part with the uncoiling blanking die, stock utilization can reach more than 80%; If one is saved the 0.2Kg material, 300,000 of volume productions can be saved 60 tons of materials, if any about the part saving reach 120 tons of materials, this is a considerable saving.
2, employing nitrogen cylinder binder of the present utility model need not be adjusted pressure during use, need not arrange and installation mold by push rod, and is very convenient.
3, plug-in type guide plate structure compactness of the present utility model is conveniently united installation.
4, the utility model compact conformation, cutter piece support firm reliable, and resilience is easy to adjust quick, can finish the work of drawing that the two caps of door anti-collision joist make progress preferably.
