The specific embodiment
The structural representation of full-vertical extrusion casting apparatus of the present invention as shown in Figure 1 as seen, this equipment comprises: clamping (I); Tiltable cast and vertical extruding, but and the injection mechanism (II) of total travel stepless speed regulation high energy injection; Two worker's rotation mechanisms (III); And closed loop circuit control system (IV) is formed.Wherein, clamping (I) has: toggle expands power formula, four and expands power cylinder formula, direct three kinds of forms of cylinder type.
As shown in Figure 2, for a kind of toggle of the present invention expands power formula matched moulds structure, comprise solid plate (I-1), moving platen (I-2), closing cylinder seat (deserving to be called crossbeam, tailgate again) (I-3), four big thick sticks (claiming brother woods post again) are (2-4), die cylinder (2-5), mode transfer parts (2-5), toggle parts (2-7) and thimble oil cylinder (2-8) etc.
As shown in Figure 4, for the present invention another kind of four expands power cylinder formula (or claiming that bimodulus is board-like) matched moulds structure, comprise solid plate (I-1), moving platen (claiming ejector half seat board, moved cross beam, middle plate again) (I-2) expands power cylinder (3-3), folding latch (3-4), four big thick sticks (claiming brother woods post again) (3-5), oil cylinder seat board (3-6) drives oil cylinder (3-7), thimble oil cylinder (3-8).This clamping is three basic company proprietary technologies, applies for a patent.
As shown in Figure 6; be another direct cylinder type clamping of the present invention; comprise solid plate (I-1); moving platen (claiming ejector half seat board, moved cross beam, middle plate again) (I-2); closing cylinder seat (deserving to be called crossbeam, tailgate again) (4-3), four big thick sticks (claiming brother woods post again) (4-4), fuel tank (4-5); die cylinder (4-6), push rod (4-7) etc.
Injection mechanism (II) need of work for ease of inclined casting and vertical extruding; guarantee the structural strength and the rigidity of frame again, the squeezing through-hole on the solid plate (I-1) is designed to towards extruding barrel off-centre, and thereunder opens half groove (referring to Fig. 2; Fig. 4, Fig. 6).
This pushes clamping (I), and it has matched moulds, die sinking and secondary extrusion function concurrently.Triformed clamping: the one, toggle expands power formula structure (Fig. 2), promptly drives the scheme that toggle (2-7) push-and-pull ejector half seat board (I-2) carries out work by the die cylinder (2-5) that is fixed on the closing cylinder seat (I-3).Two is two template types (four expand the power cylinder formula) structures (Fig. 4), drive oil cylinder (3-7) during matched moulds and drive moving platen (I-2), when mould is about to fit, the driving cylinder stop motion, folding latch (3-4) inserts, it is oil-filled to expand power cylinder (3-3) cavity of resorption, and moving platen (I-2) continues matched moulds under four large-area expansion power cylinders (3-3) effect, until reaching required mold clamping force.During die sinking, it is oil-filled to expand power cylinder (3-3) epicoele, moving platen (I-2) is at four large-area expansion power cylinders (3-3) effect lower open die, after expansion power cylinder (I-3) full stroke is opened foot, folding latch (3-4) is extracted out, drive oil cylinder (3-7) and drive moving platen (I-2) continuation die sinking, put in place until die sinking.The 3rd, direct cylinder type matched moulds structure (Fig. 6), it is the scheme of carrying out work by the direct push-and-pull moving platen (I-2) of oil cylinder (4-6) that is fixed on the closing cylinder seat (4-3).Above-mentioned three schemes all can realize matched moulds, and directly extruding is accurately located locked mode and carried out function such as secondary extrusion.
The toggle of this clamping expands power formula structure (Fig. 2); its oil piping system (as shown in Figure 3) is by die cylinder (5-6); the pinpoint travel switch of control valve (I-1-2) (I-1-2) is formed; can realize the accurate location of a certain desired location (toggle does not stretch) of matched moulds process; and can hold to a certain degree clamp force; after obtaining the instruction of closed loop circuit control system, can push matched moulds (toggle stretches) rapidly, to realize the foundry goods in the mould is implemented the function of directly extruding or dual extruding.
The bimodulus of this clamping board-like (four expand the power cylinder formula) structure (Fig. 4); its oil piping system (as Fig. 5) is by driving oil cylinder (6-7); expand power cylinder (6-3), folding latch (6-4), control valve (I-2-1) and pinpoint travel switch (I-2-2) are formed.Equally, can realize the accurate location of certain desired location, locked mode, pressurize, directly extruding and secondary push action again, can implement dual squeeze function.
The direct cylinder type structure (Fig. 6) of described matched moulds system, its oil piping system (as shown in Figure 7) is made up of die cylinder (4-6), control valve and pinpoint travel switch (I-3-2).Equally, can realize the accurate location of certain desired location, locked mode, pressurize, directly extruding and secondary push action again, can implement dual squeeze function.
This injection mechanism (as shown in Figure 8), it is suspended on solid plate (I-1) below by four suspension rods (8-3).When vertical, drive extruding barrel (8-1) by elevating ram (8-4) and do ascending motion, meanwhile the piston rod of injection oil cylinder (8-7) promotes extrusion piston (claiming drift again) and (8-2) does synchronous ascending motion, confirm extruding barrel (8-1) rise put in place prop up mould after the piston rod of injection oil cylinder (8-7) continue to promote extrusion piston (claiming drift again) and (8-2) implement injection.Injection finishes, the piston rod of injection oil cylinder (8-7) retracts extrusion piston (8-2) earlier, when extrusion piston (claiming drift again) (8-2) dropped to its connecting plate (8-5) and contacts with the cover for seat of elevating ram (8-4), cover for seat and the extruding barrel (8-1) with elevating ram (8-4) retracted simultaneously.Drive elevating ram (8-4) injection oil cylinder (8-7) and extruding barrel (8-1) carries out sideshake around lower rotary shaft (8-8) by side direction oil cylinder (8-6), pour into a mould when realizing its inclination.
The oil hydraulic system of this injection mechanism (as shown in Figure 9), it is by oil pump (II-2-1), proportioning valve (servo valve) (II-2-2), at least one accumulator (II-2-3) etc. are formed (Fig. 7).It can realize the ten sections stepless speed regulation of extrusion piston (8-2) and the high-energy injection of terminal location.Realize the speed adjusting of elevating ram (8-4) and side direction oil cylinder (8-6) action.
These two worker's rotation mechanisms (III) (as shown in figure 10), can make mould switch extruding fast between two stations produces, be the quick clamping by mould, reciprocating type (shuttle type) sliding system (10-2) of provision for disengagement (10-1) mould and oil cylinder push-pull system (10-3) are formed.It can realize that two station replacement formulas of two pairs of moulds are produced on an extrusion casting machine.First pair of mould of the place's lateral location of ascending the throne implemented cleaning---spraying process.Second pair of mould of center, place, position, type is filled in the enforcement injection---pressurize---die sinking, pickup operation are to improve the utilization rate of extrusion casting apparatus.
This closed loop circuit control system (IV) is representative by central controller (IV-1) (industrial computer or PC), comprise parameter display screen (IV-2), various sensor (temperature, pressure, displacement) (IV-3), the control system that various magnetic valves and switch (IV-4) etc. are formed, it can be preferably and stores 100 optimal processing parameters of overpaying mould (part), guarantee every pair of mould when extrusion casint is produced, running parameter is stable.When parameter fluctuation exceeded standard, equipment can be reported to the police automatically, so that reject the technology rejected casting, and in time adjusted equipment.This equipment of realization contains automatic casting, and automatic part picking, automatic spraying, warning automatically, the automatic replacement of two station moulds etc. are controlled automatically in interior overall process.
