Abstract
The invention discloses a controllable variable-temperature combined multiple-punch forming device for high-strength steel plates and belongs to the field of mechanical engineering. The controllable variable-temperature combined multiple-punch forming device is used for achieving plastic machining on the high-strength steel plates. The multiple-punch forming device for the high-strength steel plates is composed of an upper combined controllable-temperature punch set, a lower combined controllable-temperature punch set, an adjusting mechanism, a load mechanism and a rack. The upper combined controllable-temperature punch set and the lower combined controllable-temperature punch set are respectively composed of a plurality of adjustable punches, the temperature of the punches can be controlled, and the punches can move freely in the axial direction and can be located at any position. In the process of forming, the punches are heated through electrical heating according to temperature requirements of a machining process, the temperature of performing areas making contact with the punches also rises, a system is controlled to stop heating when the temperature rises to a preset value, and load forming of the high-strength steel plates is completed by the load mechanism.
Description
Technical field
It is high-strength steel sheet material to be carried out to the equipment of plastic working that the controlled alternating temperature of high strength steel plate combines many drifts building mortion, belongs to mechanical engineering field.
Background technology
Sheet material forming is the important component part of plastic working, in Aero-Space, Automobile Transportation and field of petrochemical industry, important application is arranged.
Sheet material forming needs shaping dies mostly, and wherein to account for the proportion of production cost very high for die cost.For single batch of small lot and trial production of new products, the design and manufacture cost of mould, far above material cost, is therefore explored the flexible universal mould that extensively is suitable for single batch of sheet material forming of small lot and is just seemed particularly important.
Adopt the profile surface that multipart punch can matching mould complexity, can realize very easily the adjustment of single and mini-batch production product structure by the combination of adjusting multipart punch, save in a large number production cycle and production cost.
But, along with automobile industry energy-saving and emission-reduction and light-weighted development, use in a large number the high-strength steel plates such as TRIP steel and dual phase steel in punching production at present.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 the deformation at room temperature resilience is serious, therefore often needs hot forming.
Production for 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 surfaces, and need to realize that drift heats to carry out hot forming, even for the part peculiar part, also need the temperature gradient distribution according to characteristics forming shaped curved surface in mould of material and part, so the controllable temperature multipart punch just seems particularly important.Its processing to the field high-strength steel sheet single-pieces such as Hyundai Motor, aviation and chemical industry, small lot stamping parts has important value.
Summary of the invention
For the problems referred to above, the present invention proposes the controlled alternating temperature of high strength steel plate and combine many drifts building mortion.Many drifts of High-strength plate building mortion is by upper and lower basic control unit group, built-in heater, and guiding mechanism, load maintainer and frame form.Its upper and lower basic control unit is comprised of a plurality of regularly arranged drift that can regulate and flange fixing installations.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 requiredly arbitrarily, is raised to when setting value when temperature simultaneously, can automatically stop heating.
Temperature control is partly to be wound around resistance wire as electric heating element in each drift inside, and the sparse of the thickness of resistance wire, the number of turn and winding determined by required heating-up temperature.Adopt aluminium oxide powder to add glue to mix, evenly be applied to resistance wire and drift inner tube, with the protective resistance silk, delay the resistance wire oxidation, play the effect of fixed resistance silk simultaneously.
In the basic drift of heating, also heat up in the preformed zone contacted with drift thereupon, and on this basis by automatically controlling and adjust drift position matching profile surface, and load maintainer completes the loading and shaping to high strength steel plate.

In figure: 1. blank holder 2. High-strength plate 3. thermocouple 4. resistance wire 5. drift 6. fixture 7. backing plate 8. frames
Specific embodiment this patent above-mentioned purpose is achieved in that accompanying drawings is as follows.
Consult Fig. 1: the controlled alternating temperature of high strength steel plate combines many drifts building mortion, by upper and lower basic control unit group, and guiding mechanism, load maintainer and frame form.On it, basic control unit is comprised of a plurality of regularly arranged drifts that can regulate temperature and position 5.Lower basic control unit is comprised of blank holder 1, fixture 6, drift 5, backing plate 7 and frame 8.
Forming step is: at first that high strength steel plate (TRIP steel) 2 use fixtures 6 are fixing, in order to prevent that sheet material from occurring that in forming process the defect such as wrinkling applies pressure-pad-force by 1 pair of sheet material of blank holder, then play lubrication at the surface of steel plate graphitization, to reduce the wearing and tearing of multipart punch in forming process.Before high strength steel plate is shaped, first multipart punch is heated to preset temperature according to technique, this work is completed by resistance wire 4.The forming temperature that reaches setting when temperature stops heating, adjusts the drift position simultaneously, and matching profile surface (seeing Fig. 2), then by the load maintainer loading and shaping.
