Four, aluminium alloy whirlwind frying pan liquid die-forging die basic functional principle
Below abbreviate aluminium alloy whirlwind frying pan as product.
The course of work basic principle of aluminium alloy whirlwind frying pan liquid die-forging die: upper bolster (15) is installed on the vertical hydraulic press crossbeam of 315T together with right baffle-plate (8) and right baffle plate (14), material cylinder seat (1) is fixed on the press bed surface, die shoe (16) is connected with upper bolster (15) by the removable link plate (6) on both sides, and between the material cylinder seat (1) certain space is arranged, at first with aluminium liquid cast pan feeding cylinder (3), the press crossbeam falls to making die shoe (16) to combine with material cylinder seat (1), liftout drift (2) upwards pressurization forges, and crossbeam master cylinder pressurization downwards makes patrix (5) invariant position guarantee that product forms enough pressure, and work pressurize 15 seconds, removable link plate (6) is linked together die shoe (16) and material cylinder seat (1), the press crossbeam moves upward and drives upper bolster (15) and die shoe (16) is upwards broken clout head (19) together, after removing clout head (19), the press original position that falls back, changing removable link plate (6) again makes it connect die shoe (16) and material cylinder seat (1), press makes progress again, upper bolster (15) separates with die shoe (16), product is stayed on the patrix (5), take blame for others at this moment press continues upwards (11) start, promote die pad (10) and ejector beam (12) product is released from patrix (5), finish a working cycles.
The utility model can make liquid forging break from watering aluminium liquid → forging molding → stub bar → the whole process of the product demoulding once finishes, wherein removable link plate (6) has been brought into play considerable effect.
From the process of liquid forging moulding, under the condition that does not begin as yet to solidify at molten metal: the extruding force that metal liquid stream is subjected to more slowly is abundant more, and then internal flaw is few more; The extruding force deficiency that metal liquid stream is subjected to more soon, then internal flaw is just many more.The utility model has been because adopted direct-connected big cast gate, and promptly take blame for others the down liquid forging technology of low speed roof pressure of big flow, low flow velocity has successfully solved the inadequate problem of extruding force that the too fast product of molten metal flow velocity is subjected to.From mould structure, shown in Figure 1, the suffered extruding force of product is that liftout drift (2) directly acts on the power on the alloy aluminum liquid, directly pass on the product by running channel, the liquid flow path direction is consistent with liquid forging force direction, because there is not cross gate to have only vertical running channel, product directly links to each other with clout head (19), the thrust that makes product can directly be subjected to liftout drift (2) in process of setting is pushed fully, in the forming process of product, because the heavy caliber of running channel, make running channel and clout head (19) final set always, this has just guaranteed that typing molten metal liquid stream is stable, help solidifying smoothly and feeding under pressure of product, this is the key that forms the compactness tissue, because liquid forging requires aluminium liquid to flow at a slow speed, is generally 50 mm/second, therefore easily produce surface quality defects such as cold shut, in order to prevent these generation of defects, when starting working, mould must be preheated to 150 ℃, and the cast temperature of aluminium liquid need guarantee at 680～730 ℃.
In order to make product be subjected to sufficient extruding in process of setting, the dwell time also is to guarantee that product obtains the essential condition of fine and close small grains tissue.The length of dwell time depends on the material of product, the wall thickness of product, and the cast temperature of aluminium liquid, factors such as the temperature of mould, the dwell time of the utility model liquid die-forging die is 15 seconds.
Because the cast gate of liquid forging is different with general die casting cast gate, therefore clout head (19) to break complexity also different, traditional die casting gate diameter is little, the clout head is thin, be easy to break, only depend on clout head (19) just much of that with the friction of material cylinder (3), so liftout drift (2) is made simple socket cap, and the liquid forging gate diameter increases the rough disconnected difficulty of clout head (19).Except grasping the opportunity of breaking, promptly must be in and partly solidify strong attitude and carry out withdrawing pattern clout head (19) is broken at cast gate.Also require clout head (19) in material cylinder (3), enough clamping forces must be arranged, it is not enough depending merely on that friction, the utility model is designed to dove-tail form with liftout drift (2) for this reason, and shown in part among Fig. 12, clout head (19) axial resistance strengthens when withdrawing pattern like this.Littler than material cylinder (3) interior diameter because of the cast gate place again, clout head (19) is very easy to be broken at the cast gate place, because the elder generation of the product above cast gate cooled and solidified has enough intensity, therefore also can not make product produce distortion when breaking clout head (19).
The utility model utilizes the gap exhaust of double-deck contact-making surface, and one deck is patrix (5) and counterdie (4) contact-making surface, has increased one deck contact-making surface at product bending change larger part in addition, becomes the liquid forging die of double-deck contact-making surface gas extraction system, as shown in Figure 1.Increased exhaust effect like this, can upwards be full of in the die cavity process at aluminium liquid and promptly intracavity gas be got rid of, because exhaust is to utilize contact gap, the quality that like this can exhaust influence the product surface does not again influence the extruding force that product bears yet and reduces, and air drains in the chamber, there is not air to be involved in product inside, thereby product organize fine and closely woven, no bubble, functional.
Characteristics of the present utility model are to adopt the liquid forging new technology, adopt big cast gate exactly, big flow, low flow velocity, the liquid forging method of following pushing tow pressurization.This compares with traditional casting or pressure casting method, can obtain no bubble, and crystallization is fine and closely woven, the articles made of aluminium alloy of function admirable.
The utility model is simple in structure easy to operate, distinctive feature:
The first: designed double-deck aspect contact gap gas extraction system at following impression, the characteristics of this structure are, all exhausts but whole product week makes a circle, and capacity is big, but does not influence the surface quality of workpiece.This be since when aluminium liquid is subjected to the effect of roof pressure power slowly flow to arrive place, contact slit from bottom to top intracavity gas drain, can not enter the slit owing to the resistance in slit and the tension force aluminium liquid on aluminium liquid surface when aluminium liquid contacts with the slit, and the slit is sealed.Therefore the extruding force that is subjected to of product can not descend yet, thereby can obtain the product of dense structure.Through test repeatedly, the roughness of contact gap gas extraction system two contact-making surfaces that we design is Ra6.3～12.5 optimums, sees shown in Figure 1.
It two is: in order to reach big cast gate, big flow, low flow velocity, we in the forging die bottom, will expect that cylinder (3), cast gate, product die cavity directly link to each other the shortest (see figure 1) in path to the design of forging die cast gate, gate diameter is 45 millimeters, it is 50 mm/second that speed is sent on the top of following cylinder liftout drift (2), and the impression preheat temperature is 150 ℃, and pouring into the aluminium temperature is 680～730 ℃.
It three is: the design of the nose shape of liftout drift (2), because gate diameter is big, cooling back clout head (19) is difficult for breaking, must product be in liquid and solid-state between the time break, need to increase the resistance of clout head (19) in material cylinder (3) like this, to improve its contact strength, liftout drift (2) is designed to swallow-tail form for this reason, see No. 2 part liftout drifts (2) among Fig. 1, liftout drift (2) diameter is 120 millimeters, and dovetail is wide 70 millimeters, 25 millimeters of height, the dovetail angle is 55 °, and roughness is Ra12.5.
