Abstract
The invention relates to an isostatic pressing machine, in particular to a full-automatic isostatic pressing machine for a multi-station vertical-type rotary table. A rotary table and a servo decelerator are mounted on a base of the isostatic pressing machine; the rotary table is provided with three or more working holes, and a lower die body and a die are mounted in each of the working hole; the rotary table is connected with the servo decelerator through a central bearing, the servo decelerator drives the rotary table to intermittently and oppositely rotate with an angle of 90 degrees, and enables die cavities of the lower die bodies on three working holes on the rotary table to always communicate with a distributing device unit, a compression forming unit and an automatic ejection unit when the rotary table is out of rotation. By using the structure in the invention, the isostatic pressing machine can work at a distributing station, a compression pressing station and an automatic ejection station simultaneously; and therefore, the production efficiency is greatly improved, the manpower and cost are saved.
Description
Technical field
The present invention relates to a kind of isostatic compaction machine.
Background technology
The powder compacting of known complicated shape part all adopts the isostatic compaction mode.Isostatic pressing technology is that a kind of interior goods of closed pressure vessel that utilize are in each ultrahigh-pressure hydraulic advanced technology to the super-pressure pressure state compacted under of equalization.Deng the static pressure operation principle is Pascal's law: " medium in closed container (liquid or gas) pressure can transmit equably to all directions." history in existing more than 70 year of isostatic pressing technology, the initial stage is mainly used in the powder moulding of powder metallurgy; Because the transmission of power is an isotropism in the liquid medium, the shape of product high conformity of isostatic compaction, density is even, over nearly 20 years, isostatic pressing technology has been widely used in fields such as ceramic casting, atomic energy, instrument manufacturing, plastics, super high pressure food sterilization and graphite, pottery, permanent magnet, high pressure electromagnetism porcelain vase, bio-pharmaceutical preparation, food fresh keeping, high performance material, military project.
At present, isostatic compaction machine on the market is various, but substantially all is to adopt static pressure dual modes such as static pressure such as wet bag method and dry bag method.Static pressure such as wet bag method are with the powder plasticity bag of packing into, and directly hit the person liquid pressure medium and liquid contact. therefore claim wet bag method.This method can change the shape and size of plasticity jacket arbitrarily. and the goods flexibility is very big. be applicable to small-scale production.All to pack at every turn, bleed operation, production efficiency is not high, can not carry out large-scale production continuously.Static pressure rubber bulbs such as dry bag method at first are placed in the cylinder. do not take out during work, behind the moulding plasticity bag that powder is packed into other. and put in the pressurization rubber bulb, do not contact with liquid. therefore be called thousand bags of methods.But this method continued operation is promptly opened loam cake. from loading hopper. and build loam cake then and add to be pressed into and be subjected to. during discharging. loam cake to be opened. the top rod by the bottom ejects pressed compact from the top.This method operation cycle is shorter, is applicable to and produces by batch, but because cloth, isostatic compaction and ejection are not to carry out simultaneously, influenced production efficiency.
Summary of the invention
The invention provides the full-automatic isostatic compaction machine of the vertical revolution of a kind of multistation double-workbench, make product in isostatic compaction, carry out automatic charge, automatic demoulding at other stations.
For solving above technical problem, comprise the enclosed framework of forming by die cylinder, column, base at existing isostatic compaction machine composition, on the basis of compression moulding unit that moved cross beam, template, upper die body, lower mold body, mould, pressurized cylinder unit are formed and distributing device unit, automatic ejection unit, position detection unit and hydraulic control unit, the present invention has installed the revolution equipment on base, this revolution equipment comprises two rotary tables and two servo deceleration machines of installing along the base symmetry; Have the working hole of three symmetrical distributions on each rotary table, lower mold body and mould are installed in the working hole; Rotary table links to each other with the servo deceleration machine by centre bearing, the servo deceleration machine can drive intermittently revolution in opposite directions of rotary table, and makes wherein three working holes of rotary table always place distributing device unit and compression moulding unit and automatic ejection unit respectively when rotation stops.
The course of work of the present invention is: quantitatively distributing device is evenly sent into powder in the counterdie, two servo deceleration machines drive two rotary table half-twists respectively, two groups of counterdies of having feeded enter the compression moulding unit, closing cylinder descends and makes patrix sealing counterdie and form certain mold clamping force, hydraulic control system control compression moulding unit action this moment, by forming pressure medium in the mould cylinder body rubber pattern is pressurizeed, and by the final pressurization that realizes powder of the distortion of rubber pattern, after reaching requirement pressure, release, a forming process is finished in the closing cylinder backhaul.In the pressurization pressing process, quantitatively distributing device carries out cloth to the last station of compression moulding station.After the die cylinder backhaul put in place, two servo deceleration machines drove two rotary table rotations respectively, enter next forming process.The product of compression moulding this moment station moulding enters automatic ejection unit, and vertical cylinder drives sucker product is taken out from mould, and horizontal air cylinder is delivered to product on the conveyer belt.The product that belt feeder will drop on belt is transported.So circulation forms continuously and produces automatically.
A kind of embodiment of the present invention opens four working holes on rotary table, two servo deceleration machines drive intermittently 90 ° of revolutions in opposite directions of rotary table, and make wherein three working holes of rotary table always place distributing device unit and compression moulding unit and automatic ejection unit respectively when rotation stops.It is more reasonable compact just to make the miscellaneous part of this make-up machine install with such structure, than the make-up machine of opening three working holes production efficiency is arranged more.
Another kind of examples of implementation of the present invention are that rotary table is a round platform.
Adopt above technical scheme to solve the problem that the isostatic compaction machine is worked simultaneously in cloth, compression moulding, automatic three unit of ejection, improved production efficiency, saved manpower, reduced cost.
