Abstract
The utility model relates to an upper beating device of a large-size hub isothermal forging hydropress. The upper beating device comprises a slider, an upper backing plate and a beating cylinder arranged between the upper backing plate and the slider, and is characterized in that a heat insulation plate and a heating plate are sequentially fixed at the bottom of the upper backing plate through fasteners, the heating plate is provided with a guide sleeve, the lower end of the beating cylinder is connected with an ejector rod through a fastener, and the ejector rod penetrates through the guide sleeve. The upper beating device has the advantages that by the aid of the heating plate and the heat insulation plate, the hydropress can complete hot die forging forming of magnesium alloy hubs at the low-speed work pressure of isothermal forging after an automatic-heating die is disposed and the pressure maintaining time of the hydropress is set. During forging, the temperature of the heating plate is tested through thermocouple of the heating plate, heat loss of the heating plate can be prevented by the heat insulation plate, deep and shallow cracks of workpieces are avoided, and accordingly, the shape of the workpieces pressed is uniform with the requirement of the die, and die forging effect and yield of the workpieces are guaranteed.
Description
Technical field
The utility model belongs to hydraulic machinery manufacturing technology field, particularly relates to a kind of last filling device of large-scale wheel hub isothermal forging hydraulic press.
Background technology
At present, along with developing rapidly of China's automobile industry, the automobile demand amount is relatively very high; The quality of automotive performance depends on the performance of wheel hub, and the wheel hub material property is good, can not only obtain higher safety performance and shockproof properties; But also can save automobile energy consumption, energy savings significantly, the protection environment.The most of raw material of automotive hub are main with aluminium alloy and magnesium alloy, and particularly present magnadure is that the wheel hub manufacturing industry of main flow is also developing rapidly.The heavy automobile of identical ton can be saved 20% the energy in same road conditions and the mileage after using aluminium alloy wheel hub, tire improves 25% service life, and improve 20% the service life of wheel hub itself; And magnesium alloy hub can improve 15%-20% on the basis of aluminium alloy wheel hub, and improve 15% the service life of wheel hub itself.
Adopt at present 6000 ton large-scale isothermal forging hydraulic presses to come the processing magnesium alloy wheel hub, with the narrow and characteristics of difficult deformation of the temperature range of the yield deformation that satisfies magnesium alloy hub.But in common die forging process; Because the press forging temperature keeps stablizing inadequately, pressing speed is very fast; Temperature transition speed is lower than workpiece temperature is passed to the mould lost speed of temperature afterwards, and then has influence on the die forging effect and the yield rate of workpiece, the deep mixed slight crack of workpiece can occur; Cause the yield rate of final rolled-up stock low, maybe can't suppress the shape of mould requirement.
Summary of the invention
The utility model provides a kind of compact conformation for solving the technical problem that exists in the known technology, prevent too fast loss of heat and press in forging process, play good insulation effect large-scale wheel hub isothermal forging hydraulic press on filling device.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The last filling device of large-scale wheel hub isothermal forging hydraulic press; Comprise slide block, upper padding plate and be arranged on upper padding plate and slide block between the dnockout cylinder; It is characterized in that: said upper padding plate bottom is fixed with thermal insulation board and heating plate successively through securing member; Said heating plate is provided with guide pin bushing, and said dnockout cylinder lower end connects the push rod that passes guide pin bushing through securing member.
The utility model can also adopt following technical scheme:
Said slide block is through positioning key and upper padding plate location.
Said upper padding plate is located through positioning key and thermal insulation board, heating plate.
Be provided with the adjusting pad that is used to adjust its gap between said upper padding plate and the dnockout cylinder bottom portion.
Be shaped on the bottoming hole that is used to place heater on the said heating plate.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; Promptly make press lay behind heating mould through heating plate and thermal insulation board; Press is after being provided with the dwell time; When being in the tick-over pressure of isothermal forging, can accomplish the hot forging moulding of magnesium alloy hub.In the whole forging process, come the temperature of test heater plate, and prevent the heating plate thermal loss through thermal insulation board through the thermocouple of heating plate.Avoid occurring the deep mixed slight crack of workpiece, the shape that the workpiece that suppresses and mould are required is consistent, and then has guaranteed the die forging effect and the yield rate of workpiece.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, slide block; 2, dnockout cylinder; 3, upper padding plate; 4, adjusting pad; 5, push rod; 6, guide pin bushing; 7, positioning key; 8, thermal insulation board; 9, connecting bolt; 10, heating plate; 11, bottoming hole.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, the last filling device of large-scale wheel hub isothermal forging hydraulic press, comprise slide block 1, upper padding plate 3 and be arranged on upper padding plate and slide block between dnockout cylinder 2.Said upper padding plate 3 bottoms are fixed with thermal insulation board 8 and heating plate 10 successively through securing member, and in the present embodiment, said securing member is preferably connecting bolt 9.Said heating plate 10 is provided with guide pin bushing 6, and said dnockout cylinder lower end connects the push rod 5 that passes guide pin bushing 6 through securing member, and said guide pin bushing can play guide effect in its dnockout motion process.Said slide block 1 is through positioning key 7 and upper padding plate 3 location, and said upper padding plate is through positioning key 7 and thermal insulation board, heating plate location.Between upper padding plate and dnockout cylinder bottom portion, be provided with the adjusting pad 4 that is used to adjust its gap.Be shaped on the bottoming hole 11 that is used to place heater on the said heating plate 10, to guarantee keeping forging temperature in the press forging process.Said thermal insulation board can play good insulation effect, prevents the too fast loss of heat, can guarantee also that simultaneously heat does not pass on the press main body, and then protect the press main body.
This device makes press lay after heating mould through heating plate and thermal insulation board, when the tick-over pressure of isothermal forging, and is provided with after the dwell time, can accomplish the hot forging moulding of magnesium alloy hub.The about respectively 50KW of the heating power of heating plate, the preheating heating plate came the temperature of test heater plate through the thermocouple of heating plate, and through thermal insulation board is set, prevented the heating plate thermal loss before this.
