In the invention, a structure that an installing ring of a heating furnace is additionally installed between an installing plate of an upper heating furnace and an upper mold heating furnace is adopted, so that a forging stock is arranged between molds, and in the overall process of completing isothermal forging, the heating furnace is kept closed and the mold heating furnace can provide continuous heating for the forging stock in the isothermal forging process, thereby reducing heat loss, preventing temperature reduction in the forging process of the forging stock, and realizing consistence of temperature in a slow isothermal forging process of the forging stock; and the heating device of the dynamic isothermal forging mold has simple manufacturing, strong universality and convenient operation in the process.
Description
Technical field
The invention belongs to technical field of hot working, relate to a kind of heater that is applicable to dynamic isothermal forging mold.
Background technology
Isothermal forging is meant forging stock is heated to uniform temperature, simultaneously the temperature of forging die is controlled at the roughly the same scope of blank heating-up temperature in, make blank under the constant substantially condition of temperature, finish the Forging Technology of forging deformation at a slow speed, the mold heated temperature is generally 95～105% of forging stock heating-up temperature during isothermal forging, pressure hold time general a few minutes even reach 1h sometimes to dozens of minutes during forging.Therefore, isothermal forging process requires to equip independently mold heating device, keeps constant to guarantee forging stock forging process mold temperature and blank temperature.Present isothermal forging mold heating device generally is that two heating furnaces are separately fixed on press lower and upper cross-member or the mould, upper and lower mould is heated respectively, mould and heating furnace move with the press entablature, heating furnace also is in closure state when mould is closed, mould and heating furnace were opened simultaneously when entablature was up, after forging stock was inserted between the mould, the mold heated stove just can't be closed.This mold heating device is simple in structure, forging stock is come in and gone out Mould operation conveniently during forging, but have following problem: (1) forging stock is inserted in the isothermal forging process that reaches between the upper and lower mould subsequently, the patrix heating furnace rises with mold, upper and lower mold heated stove can't be closed, causes a large amount of thermal loss; (2) blank can't continue heating at forging process, and the blank surface temperature reduces rapidly, even can cause forging crack.(3) can not form the enclosure space that continues heating between forging process mould, forging stock, be difficult to realize real isothermal forging.
Summary of the invention
The objective of the invention is: provide a kind of forging stock of realizing from inserting between the mould to the process of finishing isothermal forging the heater of the dynamic isothermal forging mold that upper and lower mold heated stove remains closed.
Technical scheme of the present invention is: the press entablature is fixedlyed connected with last mold mounting plate by connecting bolt; Last mold mounting plate is fixedlyed connected with last heating furnace installing plate, upper die plate and last forging die successively by connecting bolt; Upper die plate and last forging die place in the patrix heating furnace heating interval; The press sill is fixedlyed connected with following mold mounting plate by connecting bolt; Following mold mounting plate is fixedlyed connected with following heating furnace installing plate, counterdie backing plate, anvil tool successively by connecting bolt; Anvil tool and counterdie backing plate place in the counterdie heating furnace heating interval; The counterdie heating furnace is fixed on down on the heating furnace installing plate by connecting bolt, the diameter of last heating furnace installing plate is greater than the diameter of last forging die and upper die plate, and internal diameter greater than last heating furnace, the outer rim of last heating furnace installing plate has through hole, insert sliding screw in the through hole, sliding screw lower end and patrix heating furnace are fixed, the upper end of sliding screw and cross section are fixed for an end of the heating furnace installing ring of " Z " type, and the cross section is that the other end of the heating furnace installing ring of " Z " type is fixedlyed connected with the patrix heating furnace by connecting bolt.
The thickness of described upper die plate and counterdie backing plate can be regulated.
Advantage that the present invention has and beneficial effect: first, the present invention adopts the structure that installs the heating furnace installing ring between last heating furnace installing plate and last heating furnace additional, make forging stock placing between the mould and finishing the overall process of isothermal forging, can keep the heating furnace closure, reduced heat loss; Second, isothermal forging process mold heated stove can give forging stock and continue heating, prevented the blank temperature reduction, realized being out of shape at a slow speed under the isothermal forging condition, the uniformity of forging stock temperature, avoided deformation temperature sensitive material forging crack, and helped superplastic material realization superplastic deformation; The 3rd, by regulating the thickness of upper die plate or counterdie backing plate, realize keeping under the condition of heating furnace closure, the automatic adjustment of mould openings height can be selected suitable plate thickness according to the thickness of institute's forger part; The 4th, the heater manufacturing of isothermal forging mould of the present invention is simple, highly versatile, and process operation is convenient.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below the present invention will be further described, its concrete processing step is as follows: at first, manufacture and design isothermal forging mould and mold heated stove by universal process, employing patrix heating furnace 17,18 pairs in counterdie heating furnace are gone up forging die 5, anvil tool 7 heats respectively, and its mounting means is as follows:
A, press entablature 1 are fixedlyed connected with last mold mounting plate 2 by connecting bolt 12, and last mold mounting plate 2 is fixedlyed connected with last heating furnace installing plate 3, upper die plate 4 and last forging die 5 successively by connecting bolt 16; Upper die plate 4 places in patrix heating furnace 17 heating intervals with last forging die 5.
B, press sill 11 are fixedlyed connected with following mold mounting plate 10 by connecting bolt 21; Following mold mounting plate 10 is fixedlyed connected with following heating furnace installing plate 9, counterdie backing plate 8, anvil tool 7 successively by connecting bolt 19; Anvil tool 7 places in counterdie heating furnace 18 heating intervals with counterdie backing plate 8; Counterdie heating furnace 18 is fixed on down on the heating furnace installing plate 9 by connecting bolt 20.
Be further to optimize technology, can be by touching the thickness of backing plate 4 and counterdie backing plate 8 on adjusting, adjust patrix heating furnace 17, counterdie heating furnace 18 when closed, the minimum constructive height between last forging die 5, the anvil tool 7, forging stock 6 minimum constructive heights that just can allow.
