Abstract
The controlled combination of variable temperature of high strength steel plate many drifts building mortion is equipment high-strength steel sheet material being carried out to plastic working, belongs to mechanical engineering field.High-strength plate many drifts building mortion is by combining controllable temperature drift group up and down, guiding mechanism, and load maintainer and frame form.It combines controllable temperature drift up and down and is made up of multiple drift that can regulate, and drift temperature-controllable, can move freely vertically, and can locate at an arbitrary position.During shaping, first drift is heated up by electrical heating according to the temperature requirement of processing technology, to the pre-forming zone temperature also corresponding rising of punch. contact, when being raised to predetermined temperature, control system stops heating, and completes the loading and shaping to high strength steel plate by load maintainer.
Description
Technical field
The controlled combination of variable temperature of high strength steel plate many drifts building mortion is equipment high-strength steel sheet material being carried out to plastic working, belongs to mechanical engineering field.
Background technology
Sheet material forming is the important component part of plastic working, has important application in Aero-Space, Automobile Transportation and field of petrochemical industry.
Sheet material forming needs shaping dies mostly, and wherein to account for the proportion of production cost very high for die cost.For small lot single batch and trial production of new products, the design and manufacture cost of mould, far above material cost, is therefore explored the flexible universal mould being extensively suitable for small lot single batch of sheet material forming and is just seemed particularly important.
Adopt multipart punch can the profile surface of matching mould complexity, the adjustment of single and mini-batch production product structure can be realized by the combination adjusting multipart punch very easily, save production cycle and production cost in a large number.
But along with automobile industry energy-saving and emission-reduction and light-weighted development, in current punching production, use the high strength steel plate such as TRIP steel and dual phase steel in a large number.Under high-strength steel sheet normal temperature, resistance of deformation is high, and the required load that is shaped is apparently higher than conventional steel plates, and deformation at room temperature resilience is serious, therefore often needs hot forming.
For the production of single and mini-batch production high strength steel plate stamping parts, not only need can quick-adjustsing multipart punch with according to different part adjustment shaping Die curved surface, and need to realize drift heating to carry out hot forming, even part peculiar part is also needed to the temperature gradient distribution of the feature forming shaped curved surface in mould according to material and part, therefore controllable temperature multipart punch just seems particularly important.It has important value to the processing of the field high-strength steel sheet single-pieces such as Hyundai Motor, aviation and chemical industry, small lot stamping parts.
Summary of the invention
For the problems referred to above, the present invention proposes the controlled combination of variable temperature of high strength steel plate many drifts building mortion.High-strength plate many drifts building mortion is by upper and lower basic control unit group, and built-in heater, guiding mechanism, load maintainer and frame form.Its upper and lower basic control unit is made up of multiple regularly arranged drift that can regulate and flange fixing installation.Basic drift can move freely vertically, and can locate at an arbitrary position.In addition, the operating temperature of drift is controlled, and there is the resistance wire as calandria drift inside, can be heated to temperature required arbitrarily, simultaneously when temperature is raised to setting value, automatically can stop heating.
Temperature control part is wound around resistance wire as electric heating element in each drift inside, and the thickness of resistance wire, the number of turn and the sparse of winding are determined by required heating-up temperature.Adopt aluminium oxide powder to add glue mixing, be evenly applied to pipe in resistance wire and drift, delay resistance wire oxidation with protective resistance silk, play the effect of fixed resistance silk simultaneously.
While the basic drift of heating, also heat up with the preformed region of punch. contact, on this basis by automatically controlling adjustment forcer position matching profile surface, and load maintainer completes the loading and shaping to high strength steel plate thereupon.

Detailed description of the invention this patent above-mentioned purpose is achieved in that accompanying drawings is as follows.
Consult Fig. 1: the controlled combination of variable temperature of high strength steel plate many drifts building mortion, by upper and lower basic control unit group, guiding mechanism, load maintainer and frame composition.On it, basic control unit is made up of multiple regularly arranged drift 5 of temperature and position that can regulate.Lower basic control unit is made up of blank holder 1, fixture 6, drift 5, backing plate 7 and frame 8.
Forming step is: first fixed by high strength steel plate (TRIP steel) 2 fixture 6, in forming process, occur that in order to prevent sheet material the defect such as wrinkling applies pressure-pad-force by blank holder 1 pair of sheet material, then lubrication is played at surface of steel plate graphitization, to reduce the wearing and tearing of multipart punch in forming process.Before being shaped to high strength steel plate, first multipart punch is heated to preset temperature according to technique, this work has been come by resistance wire 4.Namely the forming temperature reaching setting when temperature stops heating, and adjust forcer position, matching profile surface (see Fig. 2), then by load maintainer loading and shaping simultaneously.
