Description

Novel inverted compound die
Technical field
The present invention relates to mould applications, in particular to the novel inverted compound die of one.
Background technology
Diel is the requisite technological equipment of punching production, is technology-intensive product, and it can carry out the processing and forming such as punching, blanking, bending and drawing.The quality of stamping parts, production efficiency and production cost etc., have direct relation with Design of Dies and manufacture.
Cup shell is a kind of conventional instrument in daily life, the shaping comparatively complexity of cup shell, need accurately to control punch forming, the cup shell specification heterogeneity that mould of the prior art processes, simultaneously easily there is slight crack when bending raw material, be therefore badly in need of a kind of mould that crudy is homogeneous that can ensure.
Summary of the invention
The invention provides a kind of novel inverted compound die, be intended to improve above-mentioned technical problem.
The present invention is achieved in that
Novel inverted compound die, comprise controlling organization, drift, upper bolster, workbench and die shoe, described upper bolster is fixed on described drift, described die shoe is fixed on described workbench, described upper bolster arranges punch, die shoe arranges concave-convex mold, described concave-convex mold is provided with vertical nib, the upper end of described concave-convex mold forms the platform for placing raw material, and described die hole location is corresponding with described punch, and described controlling organization connects described drift and drives described drift to move up and down.
Cup shell mould provided by the invention, operationally, is placed on platform by former material steel material, drift moves downward under the drive of controlling organization, upper bolster undershoot, and punch is by downward for part corresponding with nib for raw material punching press, former material steel material bends, and forms cup shell downwards in nib.Whole process completes automatically, after punching press completes, above carries drift, and the punch on upper bolster and former material steel material depart from, and cup shell is stayed in nib, can be reentered into former material steel material and work on after being taken out.
Controlling organization is controlled to carry out work by PLC control system, is completed by plug-in, so just can ensure that the parameters such as the time of each punching press, drawing velocity are consistent, makes the cup shell that stamps out homogeneous.
Further, also comprise shedding mechanism, described shedding mechanism comprises stripper and connecting rod, and described stripper connects described connecting rod, and described connecting rod stretches out described die shoe, and described stripper is arranged in described nib and also can slides along described nib.
The effect of shedding mechanism is upwards ejected by the cup shell stayed in nib after upper bolster and die shoe depart from mutually.
Specifically, after upper bolster upwards departs from, moved upward by operator link and drive stripper to move upward and the cup shell stayed in nib upwards can be ejected.Connecting rod can carry out being connected with some hydraulic cylinder equal power devices and uses automation mechanized operation.
Further, described shedding mechanism also comprises stroke pull bar, and described stroke pull bar one end connects described upper bolster, and the other end connects described connecting plate through described die shoe, described connecting plate is fixedly connected with described connecting rod, drives described stroke pull bar vertical motion during described upper bolster motion.
By arranging the stroke pull bar be connected with upper bolster, complete the action of downward punching press at upper bolster after, drift drives on upper bolster and carries, now stroke pull bar moves upward accordingly, the upwardly connecting rod corresponding to the connecting plate that stroke pull bar connects, cup shell is released nib by final stripper, completes automatic discharging, do not need again extra to arrange actuating unit, and make the operating process of compound die more coherent quick.
Further, described stripper is provided with rubber blanket, described rubber blanket tiling is fixed on described stripper.
Stripper is when promoting cup shell and deviating from nib, due to the speed that upper bolster upwards promotes, under the drive of upper bolster, cup shell also upwards can be released nib by stripper fast accordingly, effectively can prevent stripper from upwards course of action, causing the local deformation of cup shell by arranging rubber blanket, playing the effect of damping, buffering.
Further, described platform is provided with the keeper for locating raw material.
In order to ensure the cup shell uniform specification produced, punch, concave-convex mold and former material steel material answer precise positioning before stamping, by arranging keeper, former material steel material when putting into platform and punch precise positioning, ensures that the cup shell that stamps out precisely and uniform specification.
Keeper can be arranged to various ways, as long as can realize the precise positioning of former material steel material.Such as: the fixture block that some cooperatively interact can be arranged, when platform put into by former material steel material, former material steel material is fixed to same position by fixture block.
Further, described keeper is the locating piece of ring-type, and described locating piece is arranged along the circumference of described concave-convex mold.
First the former material steel material manufacturing cup shell is cut into discoid, and during compound die work, discoid former material steel material is put into the locating piece of ring-type, locating piece is blocked, and realizes the precise positioning of former material steel material.
Further, described workbench is fixedly installed die shoe pallet, described die shoe is fixedly installed on die shoe pallet.
When punching operation, die shoe will bear the huge impulsive force from upper bolster, therefore ensure its arrange stablize extremely important.Die shoe is fixedly installed on workbench by die shoe pallet, the stability that die shoe is arranged can be strengthened.
Further, described drift is fixedly installed upper bolster pallet, described upper bolster is fixedly installed on upper bolster pallet.
Same, when punching operation, upper bolster will bear the huge anti-force from bed die, therefore ensure its arrange stablize extremely important.Upper bolster is fixedly installed on drift by upper bolster pallet, the stability that upper bolster is arranged can be strengthened.
Further, described punch adopts GCr15 steel to make.
Further, described concave-convex mold adopts GCr15 steel to make.
GCr15 steel be a kind of alloy content less, there is superperformance, most widely used high-carbon-chromium bearing steel.There is higher hardness, uniform tissue, good wearability, high contact fatigue property after quenching adds tempering, be very suitable as mould manufacturing field.
The invention has the beneficial effects as follows: upside-down mounting compound die provided by the invention can realize cup shell accurately and produce, and the cup shell uniform specification produced, quality high-quality, and can also continuous automatic production be realized after being provided with the shedding mechanism of automation, the processing in enormous quantities of cup shell can be realized, be beneficial to popularization.
