Description
Technical field
The invention belongs to compressing field, be specially a kind of die device and using method thereof.
Background technology
In order to ensure die device forming accuracy in forming process and position accuracy, generally use blank holder that workpiece blank is carried out maintenance.
And after the press process of this mould, it usually needs workpiece is carried out next step process, such as surface quality and SHAPE DETECTION, heat treatment (Ageing Treatment), shape partial trim etc..After this being disposed, need from mould, open (molding) workpiece.
If blank holder is directly removed with upper mold, then when causing process after forming, the positional precision to workpiece impacts (relative to lower mold).And blank holder is stayed in lower mold, then the molding (the most automatically performing molding) to workpiece impacts.
Summary of the invention
It is an object of the invention to provide a kind of die device and using method thereof, it can overcome drawbacks described above.
nullDie device according to an aspect of the present invention，For pressing component，Including pedestal、Upper mold and lower mold，Described lower mold is supported on described pedestal，Described upper mold can be moved towards described lower mold thus by compressing for the workpiece that is positioned between described lower mold and upper mold by the pressure down of compacting drive mechanism，Blank holder it is provided with against ring portion at the outer circumference of described lower mold，At least two root posts it are further fixedly arranged on described pedestal，The circumferential edges of workpiece is folded in therebetween in order to cooperate with blank holder by described blank holder against ring portion，Described blank holder and described at least two root posts are slidably matched and can compression springs on the limiting section fixed by being resisted against place, described column upper end、And the blank holder pressing member that couples with described compacting drive mechanism and slide downward be pressed on the circumferential edges of described workpiece，It is provided with cavity portion between the base plate of described lower mold and described pedestal，Described cavity portion is provided with workpiece die lifter，Described workpiece die lifter includes the driving motor being fixedly installed on the described base plate of described pedestal，Described driving motor couples with output shaft，Output shaft is by bonded and be slidably matched with sliding sleeve，It is provided with external splines on the lateral surface of described sliding sleeve，The end driving motor is provided with radially inner extended loop，Extended loop be provided centrally with internal splined hole，It is rotatably mounted with also by bearing on described pedestal in the middle part of workpiece and ejects driving screw rod，Eject in the middle part of described workpiece and drive the lower end of screw rod to be provided with radially enlarged splined head，Described splined head is positioned in the internal cavities of described sliding sleeve，Eject in the middle part of described workpiece and drive screw rod by the screw-internal thread fit of ejection piece in the middle part of external screw thread and workpiece，In the middle part of described workpiece ejection piece by the guide frame that is fixedly installed and with described lower mold in the middle part of in pilot hole be slidably matched，In the middle part of described workpiece, the top of ejection piece is that lower mold embeds head，Described lower mold embeds a part for the profiled surface of the upper side described lower mold of composition of head，
Wherein, when described sliding sleeve slides into upper position, thread barrel can be ejected with the blank holder being rotatably mounted on described pedestal to engage and be driven, described blank holder ejects the external screw thread of thread barrel and the internal thread hole threaded engagement of blank holder ejection piece, described blank holder ejection piece is provided with upwardly extending blank holder knock-pin portion and is ejected in order to engage the downside of blank holder, and described blank holder ejection piece is also slidably matched with the bar that is vertically directed on the base plate being fixedly arranged on described pedestal；
When described sliding sleeve slides into lower position, its internal splined hole engages with described splined head and can drive and eject driving screw rod in the middle part of described workpiece.
According on the other hand, the using method of die device described above, first with described blank holder knock-pin portion, blank holder is backed down, workpiece blank is placed in position, then utilize compression spring that blank holder is pushed down the peripheral edge of workpiece blank, afterwards, upper mold and blank holder pressing member are descending, and workpiece blank is press-forming into workpiece；Afterwards, upper mold and blank holder pressing member are up, then the profile parts of the most compressing workpiece is detected and heat treatment, afterwards, first with described blank holder knock-pin portion, blank holder is backed down, recycle ejection piece in the middle part of described workpiece and act on the middle part of workpiece, thus workpiece is opened from lower mold.
By such scheme, first removing owing to have employed upper mold, blank holder is retained in the setting in lower mold, and it ensure that the positional precision of the subsequent treatment after compressing.And utilizing the operation that workpiece middle die device and blank holder die lifter be performed separately, it ensure that the automatic sequence of workpiece molding performs, and can be easy to workpiece and be loaded in die device.By being arranged on the flush bonding module in lower mold molded surface, it is possible to shape after workpiece carry out the effective demoulding rise from.And whole device uses same molding motor, it is possible to save the cost of manufacture of mould, reduce equipment complexity.By having the setting of the device of the compacting blank holders such as spring, it is possible to ensure still can blank holder be had certain desirable pressure after upper mold rises out, thus ensure the workpiece positional precision relative to lower mold.
