Description
Technical field
The utility model relates to a kind of high-strength steel sheet hot forming tool, relates in particular to the cooling pipe structure of this hot forming tool.
Background technology
In recent years, along with the light-weighted proposition of automobile and people to the pay attention to day by day of security by bus, the thermoforming part of high-strength steel sheet more and more receives automaker's favor.High-strength steel sheet is after thermoforming, and its interior tissue all is converted into martensitic structure, on the macro property; The yield strength of part is greater than 1000MPa; Tensile strength has promoted the collision performance and the fatigue strength of vehicle body, simultaneously greatly greater than 1500Mpa; The high-strength steel sheet that is used for thermoforming does not need too thick thickness yet, thereby has alleviated pts wt.
Chinese patent document CN10128889 discloses a kind of " ultra-high strength steel hot stamping forming die ", and this mould comprises upper bolster and is fixed on punch, the die shoe on the upper bolster and is fixed on the die on the die shoe, is provided with cooling-water duct in the die.
Chinese patent document CN101972814A discloses a kind of " a kind of super-high strength steel door anti-collision joist hot stamping die ", and this mould comprises combination punch-die, cooling system, coolant seal circle.Cooling system adopts boring, and the boring back is processing the racetrack tank in sealed at both ends near the piecemeal mould apart from both ends of the surface 10-50mm position; Cooling water gets into from a tank, is flowed out by another tank.The place is provided with seal groove at bosh, built-in sealing ring, and external cooling water pipe.
Chinese patent document CN1829813 discloses a kind of " hot-forming method and thermoforming member "; For the steel plate of special component be heated to austenitic temperature (Ac3) above and keep after; Carry out the shaping of end article shape, in the cooling of the forming temperature in shaping or after be shaped, the cooling velocity of martensite shop temperature (Ms point) that arrives formed parts is more than critical cooling rate; And, be that Quenching Treatment is carried out in 25-150 ℃/s cooling with average cooling rate from Ms o'clock to 200 ℃.
In order to realize being converted into martensitic cooling velocity, the cooling line design in the die cavity is most important.Method for designing of the prior art is that a plurality of tandems of inserting connect, cooling water through first insert flow to mould after, insert through other successively and from last outflow of inserting; The defective of this method for designing is: one; Along with the trend of cooling water channel, cooling water temperature is raising gradually, and its heat that can take away reduces gradually; Cause the part cooling velocity inconsistent, and finally influence the mechanical performance of part; Two, take away more heat in order to make cooling water, necessary enlargement discharge, and, can cause water flow pressure to raise because the pipeline in the die cavity is complicated, and need could satisfy by the powerful water circulating pump of configuration, increased quenching difficulty and input cost; Three, owing to there is higher hydraulic pressure, be difficult to handle the current leakage problems completely, cause the mould corrosion, increased maintenance cost, reduced die life.
Summary of the invention
The utility model technical issues that need to address have provided a kind of high-strength steel sheet hot forming tool, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
The utility model comprises: the press top shoe; On described press top shoe, install die holder; Die shoe is installed on the press following table; Patrix is installed on upper bolster to be inserted; Described patrix is inserted and is comprised that go up being shaped more than at least 2 insert; Counterdie is installed on described die shoe to be inserted; Described counterdie is inserted and is comprised that go up being shaped more than at least 2 insert; It is identical with the number of descending to be shaped to insert that described last shaping is inserted; Also comprise: water inlet row and upper water-out row on the upper bolster, and following water inlet row and following water outlet on die shoe are arranged; Described each water inlet of going up among the water inlet row links to each other with each delivery port during described upper water-out is arranged through being arranged in first cooling-water duct that is shaped each on inserting; Each water inlet among the described down water inlet row links to each other with each delivery port among the described row of water outlet down through being arranged in each second cooling-water duct that is shaped down on inserting.
Compared with prior art, the beneficial effect of the utility model is: practiced thrift material cost, reduced difficulty of processing, realized better cooling effect, improved the part quality.
