Description
Technical field
The present invention relates to the hot press-formed technology field of high strength steel more particularly to a kind of heating system and prepares subregion and add
The method of hot high strength steel plate.
Background technique
With the fast development of Global Auto industry, energy shortages and environmental pollution phenomenon are increasingly severe.How energy is improved
Source utilization rate reduces environmental pollution and pays close attention to by all circles, and reasonable, effective body lightening measure is for energy-saving and emission-reduction to pass
It is important.In order to guarantee that occupant safety, various high strength steels are widely used in vehicle body crashworthiness while realizing body lightening
The design and producing of part.However, plasticity at room temperature is substantially reduced, forming property as armor plate strength is gradually increased
Deteriorate, when being formed using conventional ones technique, it may appear that shaping load is excessive, die wear is serious, plate creases easily, opens
A series of problems, such as splitting.To solve the above problems, high strength steel heat forming technology comes into being, principle are as follows: by microstructure
A is heated to for ferrite+pearlite high strength steel platec3The above a certain temperature, it is equal to obtain that resistance of deformation is small, elongation percentage is big
Plate is then transferred quickly to Quick-forming in the stamping die with cooling system by even austenite structure, and pressure maintaining, is quenched
Fire makes it thoroughly be converted into full martensitic structure, significantly improves the integral strength of part after forming.
Since body of a motor car is the labyrinth for needing to bear a variety of different form load, blindly increase its structure
Whole intensity can not obtain optimal crashworthiness effect.Currently, for certain hot forming bodywork parts, such as: hot forming B column knot
Structure often needs its top that there is high intensity to invade with Collision-free, and bottom moulding with higher deforms energy-absorbing, i.e., entirely
There are soft or hard subregions for B-pillar structure.
Currently, there are two types of common methods can realize the soft or hard subregions of thermoformed parts, it may be assumed that the cooling heat forming technology of subregion and
Partition heating heat forming technology.Refering to fig. 1 and Fig. 2, the former refers to the complete austenitizing before forming of entire plate, by changing
The cooling rate for becoming hardening phase plate different zones realizes soft or hard subregion, and the latter refers to different by plate before changing hot forming
The heating condition in region obtains different austenitizing states, and soft or hard subregion is realized after rapid quenching.It is cold relative to subregion
But for heat forming technology, partition heating heat forming technology has a clear superiority:
1. the soft or hard subregion of part can be realized under the premise of not changing traditional hot-forming die；
2. can avoid in the cooling heat forming technology of subregion, cooling rate is reduced to generate soft phase, influences production week
The problem of phase；
3. avoiding energy loss caused by cooling compensation by appropriate heating, improving efficiency.
Relative to the cooling heat forming technology of subregion, partition heating heat forming technology is still in the early stage of development, technology Shang Bucheng
It is ripe.Currently, there are mainly two types of the heating methods with development potentiality: shunt resistance heating method and induction-contact heating method.
Refering to Fig. 3, in shunt resistance heating method, since copper billet has biggish cross section and lesser resistivity,
Thus electric current can flow primarily through copper billet, and less flow through the plate region being in contact with it, and cause the region plate heat production less,
To realize the partition heating of plate.
Refering to Fig. 4, in induction-contact heating method, passed using contact plate contact between plate of induction heating
Heat heats plate.By controlling the temperature of two pairs of contact plates, the partition heating of Lai Shixian plate.
However, above two partition heating mode at present still in the laboratory study stage, is only used for simple, small lot
Experimental study.Only by arranging that shunt resistance heating or induction-contact heating equipment are difficult to match practical punching press beat on a small quantity,
It is unable to satisfy the demand industrially produced in batches；And shunt resistance heating or induction-contact heating equipment are arranged on a large scale not only
Need individually to control each equipment, it is also necessary to occupy huge space, while be unfavorable for heating after plate in the production line
Rapid transport.Therefore, it is necessary to design a kind of heating system of high strength steel partition heating heat forming technology, which can be mentioned
For partition heating high strength steel plate needed for partition heating heat forming technology, while practical punching press beat can be matched, met
