Description
Technical field
The utility model belongs to superhigh intensity part hot forming manufacturing technology field, relates to a kind of superhigh intensity part hot-forming die and inserts.
Background technology
At present, tensile strength exceedes the hot formed process program of the many employings of shaping of the part of the steel plate of 980MPa, and this process program has two kinds of concrete technologies:
The outer quenching technical of production line: formation of parts under steel plate room temperature---part heating after being shaped---is pressed and is quenched.
Mould internal shaping+quenching technical: steel plate heating---Quick-forming in mould---is quenched in mould.
The outer quenching technical of line need to heat the part being shaped, and then presses and quench, technical process relative complex, and element precision is not easy to guarantee.
Mould internal shaping+quenching technical is the main flow technique of current ultrahigh-strength steel plates part forming, and its technical process is as follows:
The heating of special high strength boron alloyed steel is made it to austenitizing, make, after its complete austenitizing, to move quickly into mould, punching press fast, needs pressurize a period of time that part shape size is tended towards stability after stamping.In shaping and pressure maintaining period, in order to prevent plate strength decreased, carry out Quenching Treatment to obtain the superhigh intensity part at room temperature with even martensitic structure simultaneously.
Hot forming technology not only has high-intensity advantage, and material plasticity under high temperature, formability are good, stamping parts that can once-forming complexity; Under high temperature, be shaped and can eliminate springback influence, element precision is high, and forming quality is good.Heat forming technology is broken the normal procedure, novel, is the cutting edge technology in stamping field, can be widely used in the production of the members such as the forward and backward bumper of automobile, A post, B post, C post, roof framework, car bottom framework and inner plate of car door, door anti-collision joist.
In order to realize mould, the part after being shaped is pressed and quenched, mould must carry out cooling, the method extensively adopting is at present to output a rule water channel in the mould inner side of pressing close to die face, utilize constantly mobile cooling water to carry out cooling to mould, make the temperature fast-descending of the formation of parts that is attached to die surface, realize the transformation of metallographic structure.These water channels need to be processed on five axle machining centers, or by complicated three-dimensional grips, adjust position and the angle of die insert, recycling drilling machine processes, a lot of holes need to tilt to process, and hole depth, footpath is little, quantity is many, in process, hole whole die insert that goes wrong is scrapped, and Mould Machining difficulty is large, expense is high.At present, the domestic producer that can carry out this hot-forming die processing is very few.This has had a strong impact on applying of ultrahigh-strength steel plates part heat forming technology.
Summary of the invention
The technical problems to be solved in the utility model is that a kind of manufacturing process is simple, cost is low, current are unimpeded, the good superhigh intensity part hot-forming die of plate quenching effect is inserted.
In order to solve the problems of the technologies described above, high strength part hot-forming die of the present utility model is inserted and is comprised punch base plate, punch insert body, die plate insert body, die base plate; The opposite face of described punch insert body and die plate insert body is die face, and another side is processed with water channel, isolated, and the surrounding of water channel is sealed by sidewall sections between each water channel by partition wall; Surface and punch base plate that punch insert body is processed with water channel are connected and fixed, surface and die base plate that die plate insert body is processed with water channel are connected and fixed, and the joint face of punch insert body and punch base plate is sealed by all sealing rings in upper edge, the joint face of die plate insert body and die base plate is sealed by all sealing rings in lower edge.
After part is at high temperature stamping by die insert, in the water channel of punch insert body and die plate insert body, pass into cooling medium, utilize constantly mobile cooling medium to carry out cooling to die insert, make the temperature fast-descending of the formation of parts that is attached to punch insert body and die plate insert body die face, realize the transformation of metallographic structure.
Described water channel is four prism type or semicircle cylindricality.
Because water channel is machined in the surface of punch insert body and die plate insert body, can adopt Milling Process, technique is simple, and processing cost is low; The utility model has the advantages that die insert manufacturing process is simple, cost is low, the inner lead suface processing quality of inserting is high, current are unimpeded, good to plate quenching effect.
The Surface Machining being connected with punch insert body of described punch base plate has along all grooves, and all sealing ring parts in upper edge are embedded in this along in all grooves.
The Surface Machining being connected with die plate insert body of described die base plate has along all grooves, and all sealing ring parts in lower edge are embedded in this along in all grooves.
Described punch insert body is processed with the surface of water channel and punch base plate and by alignment pin, locates and pass through screw fastening.
Described die plate insert body is processed with the surface of water channel and die base plate and by alignment pin, locates and pass through screw fastening.
Sealing by "O"-ring along week of described alignment pin and screw.
