Description
Technical field
The utility model relates generally to light-alloy (aluminium alloy, magnesium alloy) sheet stamping forming field.
Technical background
Safe and environment-friendly is the two main lines of China Automobile Industry.Aluminium alloy has that density is little, specific strength is high, corrosion resistance
By force, the advantages of shock resistance is good, recycling ability is strong, will become the light material most competed in auto industry.Aluminium alloy
At ambient temperature its stamping formabilily is poor, and elongation percentage is low, easy to crack during shaping, limits the application of aluminum alloy plate materials.
Aluminium alloy can obtain at high temperature more preferable plasticity, occurred aluminium under the high temperature such as ausforming, superplastic forming at present and closed
Golden Board Forming process, but forming speed is relatively low, high cost.The utility model proposes a kind of temp auto-controlled hot stamping die, can be real
The high efficiency, low cost shaping of the breadth light alloy plates such as existing aluminium alloy.
The content of the invention
A kind of efficient hot stamping forming die of breadth light alloy plate described in the utility model is in conventional cold punching die base
On plinth, mould heating and temperature-controlling system are increased, realize automatically controlling for mold temperature.Traditional dies are generally by die holder, mould
The structure compositions such as core, blank holder, blank location-plate, flanging guiding, mould guiding.The utility model increased mould heating and control
Warm system, cooled plate, thermal insulation layer, adiabatic periphery etc..
According to a series of bottoming holes of die face arrangements on core rod, heating rod is placed in bottoming hole, on core rod
Point for measuring temperature monitoring core temperature is also set up, the work of heating rod is controlled.The monitoring that heating rod passes through point for measuring temperature, carries out packet control
System, is separately controlled heating to core rod different-thickness region, and thin region first reaches heating rod after the temperature range of setting and enters guarantor
Warm heating mode, the heating rod in thick region still carries out heating, adds also into insulation after it reaches the temperature range of setting
Heat pattern.Packet control, partition heating mode are very beneficial for ensureing the consistent uniformity of core rod bulk temperature, and then are conducive to
The deformation of alloy plate material in warm punching course.
Increased the structures such as cooled plate, thermal insulation layer, completely cut off die holder and core temperature, it is ensured that die holder under normal temperature state,
Avoid press table temperature from raising to cause to damage.Core rod outer wall reduces core rod radiating by one layer of adiabatic periphery parcel.
Thermal insulation layer, cooled plate are arranged on core rod, and core rod is connected on die holder by T-bolt, and blank holder is placed on pressure
In flange support block, with nitrogen spring as pressure-pad-force source, blank location-plate be used for carry out blank positioning.Core rod, mould
Positioned using centered cylinder between seat, water-cooling section etc., set expansion origin, then arrange that four direction key limits thermal expansion side
To, thus be avoided that die swell shift；Using prominent flange flange, with T-bolt the connection of core rod and die holder is carried out.

Specific embodiment
The utility model is described further below according to accompanying drawing.
As shown in figure 1, upper cooled plate, upper thermal insulation layer fix position by center positioning hole and surrounding positioning key and upper mold core
Put, the flange flange in upper mold core has open slot, is connected with upper bolster by T-bolt, at the same compress upper cooled plate and on every
Thermosphere.The adiabatic periphery of upper mould is arranged on the heat transfer for completely cutting off upper mold core and extraneous air outside upper mold core.Lower cooled plate, under it is heat-insulated
Layer fixes good position by center positioning hole and surrounding positioning key with lower mold core, and the flange flange in lower mold core has open slot, leads to
Cross T-bolt to be connected with die shoe, while compressing lower cooled plate and lower thermal insulation layer.The adiabatic periphery of lower mould is arranged on outside lower mold core
Portion, completely cuts off the heat transfer of lower mold core and extraneous air.Blank holder is placed on blank holder cushion block, blank holder blank positioning installed above
Plate, positions to blank.
As shown in Fig. 2 meeting dilatancy after core rod heating, fixed at the centrally disposed center of core rod in order to solve this difficult problem
Position hole, by round pin centralized positioning is completed, and this center also serves as core rod expansion origin；And surrounding positioning key is set on the side of core rod four
Groove, to core rod, all around direction limits.Flange flange on core rod has open slot, is connected with die holder by T-bolt.
As shown in Fig. 2 core rod end face arranges with the shape a series of placement heating rod in bottoming holes, bottoming hole to carry out adding to core rod
Heat, and some temperature monitoring points are set on core rod, core temperature is monitored, each temperature monitoring point monitoring respective area
Core temperature in domain, is controlled to the heating rod in the region, when area's core temperature reaches the temperature value of setting, heating rod
Into heat insulation work state, if area's core temperature is less than the temperature value of setting, heating rod enters heating work state.
The efficient hot stamping forming die sequence of movement of breadth light alloy plate is as follows：First core rod is heated before die holder work,
After the temperature of upper and lower core rod reaches the temperature value of setting, blank holder jack-up in the presence of nitrogen spring subsequently, uses manipulator
The blank for heating is placed on blank holder, centering positioning is carried out by blank location-plate, manipulator is withdrawn from, and press is descending,
Upper mold core is pushed and contacted with blank holder, compresses blank, and subsequently, upper mold core is descending together with blank holder and blank, and matched moulds is completed into
Shape；After pressurize for a period of time, the stamping parts for having shaped is taken out in die sinking, and being placed into semi-finished product area carries out air cooling, completes whole shaping
Process.Subsequently blank holder jack-up in the presence of nitrogen spring, prepares next forming process.
