Oil cylinder is separated into two stand-alone assemblies.
16 tons of powder rapid shaping press, demoulding mechanism use demoulding cam and add the machine for assisting pneumatic component
Structure.
Embodiment:
The structure of 16 tons of powder rapid shaping press is broadly divided into 7 parts, and driving mechanism, crankshaft demould cam mechanism, center
Lever apparatus, press supporting mechanism, demoulding lever mechanism, upper beam mechanism, Machine tool box body.
Driving mechanism is by motor (30), small belt pulley (31) big belt pulley (1), driving triangular belt (32), pneumatic clutch
(2) it is formed with single-stage cycloidal pinwheel reducer (3).In control system access failure, brake block (4) under spring force,
Main shaft (6) is braked.Big belt pulley (1) dallies on input shaft；When solenoid valve is connected, compressed air is by pneumatic clutch
(2) it combines, and is pressed on the bonding pad (5) of belt pulley, drive the input shaft of single-stage cycloidal pinwheel reducer (3), it is defeated
Shaft transmits torque to main shaft (6).
Motor (30) is rotated by small belt pulley (31), driving triangular belt (33), big belt pulley (1), transmission main shaft (6),
And drive therewith with the crankshaft of key connection (7) rotation, sliding block (8) swings, and U-shaped take-up housing (9) is driven to move up and down.Simultaneously
Pull rod (10), active pressing plate (11) and upper beam (12) is driven to synchronize and move up and down to form compacting movement.Upper beam (12) is up and down
Reciprocal distance is 110mm.
When active pressing plate (11) is pressed in from dynamic pressure plate (13), drives from dynamic pressure plate (13) and overcome reset cylinder (14)
Thrust move down, while driving center-pole (15) downwards, form synchronous pressure braking and make, until being parked in branch from dynamic pressure plate (13)
Until on spacer block (16).
When using press, (distance of stretching is to press stroke) is stretched out in press adjustment screw (17) in advance will be from dynamic pressure
Plate (13) is pushed into support limit stop (16), and at this moment, shaping position is not yet arrived in upper punching, must continue downwards, and force press oil cylinder (18)
Oil extraction (being detailed in hydraulic schematic diagram) makes to be flushed to up to shaping position to be suppressed to form third time.
Adjustment of the upper punch with respect to machine stationary plane is by gear (28) in upper beam (12), screw thread pair (29) come real
Existing, regulated quantity is 0 ~ 60mm.Upper punch rising is rotated clockwise, otherwise declines (see the preloading action diagram of upper male mould).Often
It circles, distance change amount is 0.16mm.
During upper beam (12) moves downward, first is carried out by the stamping intrusion cavity plate being mounted on cope plate first
The secondary compression to powder then pushes center-pole (15) to move downward, is connected on center-pole (15) by active pressing plate (11)
T-shaped block (19) pull cavity plate move downward, to realize synchronous compacting.Pass through regulation relief valve (20) to 170bar in advance
It is 2.4Ton that (cannot be used above in this setting value), i.e. maximum, which synchronize lower pressure,.It is recessed when this device is used to control press
It mould forced-floating and suppresses three times, no press is not limited to the above when suppressing.Therebetween, to make product reach even density, so
Certain journey sliding block (21) is being designed from dynamic pressure plate (13) lower part.One downward force suffered when can undertake cavity plate with step is (most
Big load 8Ton).Secondly making cavity plate to this stopping.Since upper punch continues traveling downwardly, the interior pressure of press oil cylinder (18) increases, pressure
When power is more than setting value 170bar, oil in press oil cylinder (18) is by overflow valve (20) overflow to cabinet, to realize the
Three parities suppress (press).Hydraulic oil presses oil cylinder (18) by refoulement when to next pressing cycle.
Main shaft (6) rotates, and the demoulding cam (22) on main shaft pushes guide rod (23) to move upwards, and is changed by lever (24)
To, by center-pole (15) pull down to demoulding complete position (shown in upper figure).
Pressing position of the present invention is constant, and de-molding position is the demoulding row needed according to product by being mounted on center-pole (15)
Journey adjusts gear (25) adjustment.Maximum stripping stroke is 40mm.
After stripping action, center-pole (15) together with cavity plate return to charging position during, not as blank at
Constraint during type by various structures, but under the action of reset cylinder (14), milli is unobstructed to return to charging bit
It sets.
Work loading height be it is adjustable, machine maximum work loading height be 70mm(pressing stroke+stripping stroke), can distinguish
Adjustment is realized by two groups of charging gear adjustment mechanisms (26) on center-pole (15).It rotates clockwise, packed height increases, instead
Reduction.
After pressing stroke, before stripping action not yet starts, center-pole (15) is together with cavity plate by reset cylinder
(14) it acts on, it is made to have the tendency that one moves upwards.Especially when part is relatively thin, this phenomenon is more significant, and formation of parts is easy
It is damaged.Equally, the top of flange shape part is also compared with cracky.To prevent this from occurring, cavity plate need to be balanced and reset (filling)
Pressure on the downside of cylinder piston terminates in compacting, before demoulding occurs, reset cylinder (14) epicoele is made to be passed through compressed air, with
This balances reset force.To prevent center-pole (15) and cavity plate from moving upwards, to guarantee moulded blank in concave die cavity not
It is destroyed.This function is referred to as cavity plate and keeps being also known as cavity plate equilibrium.
In the undesirable situation of compatibility of evolution air and powder, when upper punch rises rapidly after pressurization,
It is expanded suddenly always present in compressed air in formed products, product is also easy to produce crackle.To prevent blank after molding from demoulding
Into cracking is generated, present invention employs convex tools to preload demolding structure.There is a pre-add carrier gas cylinder in upper beam (12)
(27), as being not required to pre-loaded function when demoulding, then pre-add carrier gas cylinder (27) cavity of resorption is ventilated always pushes piston to cylinder upper end, this
When upper male mould and upper beam (12) synchronization action.Pre-loaded function is added when such as demoulding, then before upper male mould reaches compacting point,
Because of the upward counter-force for the blank that piston is subject to.Therefore, piston is still pushed back the top of pre-add carrier gas cylinder (27), when upper male mould mistake
When compacting point, the piston just stretching from pre-add carrier gas cylinder (27) is slightly compressed to upper male mould always on blank, until blank is from recessed
Until deviating from mould.Blank stops supplying immediately once abjection, pre-add carrier gas cylinder (27) epicoele, promotion of the piston in cavity of resorption air pressure
Under retract rapidly upward, complete entire movement.Controlling piston action is realized by two two-bit triplet solenoid valves, solenoid valve
On-off can be set in display screen as needed.
The power that upper male mould preloads is stepless changing, it is realized by the pressure reducing valve in pneumatic system.
By the hydraulic device schematic diagram of 16 tons of powder rapid shaping press of Fig. 8 it is found that oil pressure is divided into 3 pressure ratings,
Respectively 5-7.5bar, 0-2.5bar and normal pressure.Supply press oil cylinder (18) first after oil pump goes out oil pump, makes in two oil cylinders
Full of hydraulic oil.More than 5-7.5bar(depending on the pressure that 0-2.5bar overflow valve (20) is set) hydraulic oil provide respectively again
To sliding bearing lubricating and spray lubrication.
16 tons of powder rapid shaping press of the invention, it is characterised in that be to integrate mechanical, electrical, air-liquid full-automatic dry
Powder molding equipment, system the operation is stable is reasonable in design, and low with manufacturing cost in volume production, function is strong, is powder smelting
