Abstract
A multistation rotating powder automatic press is a powder forming equipment used in the field of powder metallurgy technology, which aims at the problems that the current multistation rotating powder automatic press only can realize single press, the density uniformity of casting dies is bad and the compatibility is bad, the utility model adds a precompression wheel pair and a powder charge height setting device, thereby realizing the compound compression function to complex elements, the utility model has simple structure and high efficiency, every portion of the powder tablet has uniform density, the compatibility is good and the utility model can compress complex structures with steps and can be used in automatic forming of powders as magnetic materials, ceramic materials, carbide alloy and powder metallurgy.
Description
Technical field: the utility model is a kind of powder compacting apparatus, is used for powder metallurgical technology.
Background technology: the working method of multistation (8-9 the station) rotation that the existing rotary dry powder shaping of the multistation mo(u)ldenpress that is used for fields such as magnetic material, ceramic material, carbide alloy, powder metallurgy is the upper and lower two-way compacting of employing, once be pressed into.This press has only a pair of compacting wheel right, and powder is only through once compacting, thereby the uniformity and the uniformity of the powder compact density that extrudes are good inadequately.The kind of the briquetting of producing also is subjected to certain restriction.
Summary of the invention: in view of the problem that prior art exists, the purpose of this utility model is to provide a kind of multiple compression functions that has, make each position density of powder compact evenly, the rotary powder mo(u)ldenpress of multistation of high conformity.The utility model is the improvement to the existing rotary powder mo(u)ldenpress of multistation structure, on original design basis, has increased that a pair of multiple pressing roller---pre-pinch roller is right, makes powder pre-stamped to being subjected to before once through main pinch roller.When compacting has the rolled-up stock of inside and outside step, make the powder in the die cavity flow the die cavity of the good step part of filling in advance.When carrying out the secondary roof pressure, each position has formed the isodensity flow of powder and has distributed in the die cavity at main pinch roller.The utility model by support, drive train, main shaft, track, feed appliance, pre-pinch roller to, main pinch roller to, go up mould, former dish, mould and governor motion are formed down.Support is positioned at the bottom of complete machine, and drive train is equipped with in the support the inside, and main shaft vertically is contained on the support, on descending certainly track, following mould, former dish and last mould is being housed respectively on the main shaft.On last mould, former dish and following mould, patrix, former and counterdie are housed respectively.Feed appliance is housed above complete machine, and powder is sent in the negative impression on the former dish by flexible pipe, pre-pinch roller to main pinch roller to being loaded on respectively on the support that is fixed on support.Track is pressed the design of powder forming process curve, realizes the motion of pressing process mould by it.The powder filling height adjustment mechanism of being made up of a pair of worm and gear and rising screw rod is equipped with in bottom at following pre-pinch roller and following main pinch roller.Use the utility model, at first powder, is driven three moulds (go up mould, former dish, mould) down by the drive train of this machine and rotates synchronously around main shaft by setting speed in delivery hose is sent to the die cavity of former dish by feed appliance.Powder in negative impression through pre-pinch roller to main pinch roller to twice compacting after, be pressed into powder mass (blank), and deviate from negative impression, finish the pressing process of a product.The utlity model has multiple compression functions, is a kind of mo(u)ldenpress simple in structure, sinuous.The revolving structure of multistation has determined it to have very high productivity ratio, and per minute can be produced 100-200 spare product; Since the utlity model has and press work again, thus the structural member that has step can be suppressed, and guarantee that each position density of powder compact is even, high conformity.It can be used in the fields such as automatic forming of briquettings such as magnetic material, ceramic material, carbide alloy, powder metallurgy.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.Among the figure: 1, feed appliance; 2, go up pre-pinch roller; 3, go up main pinch roller; 4, patrix; 5, go up mould; 6, former; 7, former dish; 8, counterdie; 9, following mould; 10, following pre-pinch roller; 11, following main pinch roller; 12, flywheel; 13, support; 14, motor; 15, track; 16, governor motion; 17, flexible pipe; 18, main shaft.
The specific embodiment:
As shown in drawings: support 13 is positioned at the below of complete machine, and the drive train of being made up of motor 14, flywheel 12 and belt etc. is housed in support 13; Main shaft 18 vertically is contained on the support 13, is being fixed with track 15, following mould 9, former dish 7 and last mould 5 respectively on the main shaft 18 on descending certainly; On last mould 5, patrix 4 is housed, former 6 is housed on former dish 7, on the mould 9 counterdie 8 is being housed down; Feed appliance 1 is housed above complete machine, and feed appliance 1 contacts with former dish 7 by flexible pipe 17; It is right with the pre-pinch roller of down pre-pinch roller 10 compositions to go up pre-pinch roller 2, it is right with the main pinch roller of down main pinch roller 11 compositions to go up main pinch roller 3, wherein main pinch roller is to being that to form the final compacting wheel of powder compact right, and pre-pinch roller is to being to precompression of powder in the negative impression before main the pressure, make powder produce one and flow in advance, guarantee the density uniformity and the uniformity of the final compacting of powder compact.Go up pre-pinch roller 2, down pre-pinch roller 10 and go up main pinch roller 3, main pinch roller 11 is separately fixed on the support down; Powder filling height adjustment mechanism 16 is equipped with, the threaded adjusting mechanism that this height adjustment mechanism is made up of a pair of worm and gear and rising screw rod in bottom at down pre-pinch roller 10 and following main pinch roller 11.
Claims (2)
1, a kind of comprise support, drive train, main shaft, feed appliance, main pinch roller to, go up mould, former dish, mould is at the rotary powder mo(u)ldenpress of interior multistation down, it is right to it is characterized in that this press also is equipped with a pre-pinch roller, in the bottom of following pre-pinch roller and following main pinch roller height adjustment mechanism is housed also.
2, the rotary powder mo(u)ldenpress of multistation according to claim 1 is characterized in that said height adjustment mechanism is the threaded adjusting mechanism that is made of worm and gear and rising screw rod.
