Description
Technical field
The invention belongs to mechanical engineering field, be specially a kind of sheet material non-isothermal forming die device, be mainly used in the non-isothermal punching forming of plate accessory, material can comprise difficult molding metallic material under the normal temperature such as magnesium alloy, aluminium alloy, titanium alloy.
Background technology
The drawing of plate accessory is shape and size of utilizing punch, die and blank holder that sheet metal deformation is become to need.This forming technology is because of its high production rate, and low cost and good quality production quality have obtained using widely in industrial production.Yet, a large amount of punching production behavior at present is to carry out at normal temperatures, cause the high specific strength material of people's pay attention to day by day because of environmental protection and energy saving for some, as magnesium alloy, aluminium alloy and titanium alloy etc., because their relatively poor at normal temperatures plasticity has seriously limited these materials as the application of stamping products in industry.A large amount of experiments is verified, and under heating condition, these materials all show the plastic deformation ability that significantly improves.Therefore, can effectively improve difficult moulding material under these normal temperature forming property the temperature or hot press-formed technology will certainly be widely used.
In the past temperature or hot press-formed device can be divided into isothermal drawing and non-isothermal punching forming.A large amount of experiments and theoretical proof non-isothermal punching forming can effectively improve the crystallized ability of material.Yet Bao Dao non-isothermal punching forming device all adopts heating element heater that die and blank holder are heated simultaneously in the literature, and some adopts water or other liquid that punch is cooled off simultaneously.This press molding equipment can form the temperature field that is beneficial to drawing effectively in blank inside, yet the die entrance of high-temperature conducts near the heat of crushed element owing to have very, cause this part blank to have too high temperature, the low-intensity that blank shows under too high temperature has increased the possibility of its fracture significantly.
Be further to improve the deformability of difficult moulding material in non-isothermal punching forming under the normal temperature, the present invention proposes a kind of non-isothermal punching forming device that has improved.
Summary of the invention
The object of the present invention is to provide a kind of sheet material non-isothermal punching forming device,, further improved the deformability of difficult moulding material in non-isothermal punching forming under the normal temperature by improvement to traditional non-isothermal punching forming die device.
Technical scheme of the present invention is:
A kind of sheet material non-isothermal punching forming device has punch, die, blank holder, and the blank corresponding with the punch pressing direction places between die, the blank holder, and the blank holder top is provided with heating system, and the die bottom is provided with cooling system.
Described heating system is the heating plate of built-in heater coil or other heating element heater.
Described cooling system is the coldplate of built-in circulating fluid.
Described sheet material non-isothermal punching forming device is fixed on the punch and the built-in isothermal liquid circulatory system of convex mould base on the convex mould base.
Described place in punch and the convex mould base the constant temperature circulatory system by circulating fluid, be located at convex mould base or punch the circulating fluid input, be located at the circulating fluid output of punch or convex mould base and be arranged in punch and the mozzle of convex mould base constitutes.
Described sheet material non-isothermal punching forming device also is provided with the thermocouple that is used to test blank holder and die temperature, and the controller that is used to regulate heating system power.
Typical press forming die device is by punch, and die and blank holder are formed.For difficult moulding material such as magnesium alloy under some normal temperature and part aluminium alloy, for improving the forming property of sheet material, press forming die also needs supporting heating-cooling device.Non-isothermal punching forming die device of the present invention, only blank holder is heated, the die proper site adopts the circulating fluid cooling, very fast to guarantee after putting into the blank matched moulds at blank holder, formation temperature gradient in blank and the die, guaranteed that the blank flange position that will be out of shape has sufficiently high temperature, low simultaneously die temperature, particularly the low temperature in die entrance place can effectively avoid being out of shape the fracture that blank causes undercapacity to take place owing to temperature is too high, and the circulating fluid that adopts constant temperature in the punch is to guarantee that punch keeps a metastable temperature in forming process.To the blank holder heating, the die lower surface is adopted the circulating fluid cooling by this, in punch, use the method for constant temperature circulating fluid simultaneously, can obtain the stable formation process conditions, improve the forming property of sheet material simultaneously.
Advantage of the present invention is as follows:
1, the present invention compares with existing non-isothermal punching forming device, only blank holder is heated, simultaneously the die proper site is adopted the circulating fluid cooling, to guarantee after putting into blank, blank holder and die matched moulds, in blank holder, blank and die, form a rational temperature gradient very soon, so both guaranteed the high temperature in blank flange position that to be out of shape, simultaneously the die entrance position has a low temperature, avoided near the die entrance blank crushed element because the fracture that too high die temperature causes.
2, the isothermal liquid circulatory system of punch of the present invention inside guarantees that punch keeps a stationary temperature in forming process, helps formulating stable forming parameters.
3, the present invention has saved the needed energy owing to only heat blank holder.
