Said main cylinder assembly installed at upper part of main body consists of main cylinder, and nested cylinder fixed to the top of piston rod of main cylinder. Its advantages are less tensional deformation, high rigidity, and high machining accuracy. It is suitable for shaping the workpiece with complex shape and central hole.
Description
Technical field
The present invention relates to a kind of powder compaction equipment, particularly a kind of pretension frame-type precision form powder press.
Background technology
Powder metallurgy is to make metal dust and be raw material with metal dust (comprise and sneak into non-metal powder), the technology of usefulness shaping-sintering process manufactured materials and goods; Powder press is a powder pressing equipment, is used for metal dust (perhaps sneaking into non-metal powder) is pressed into required part product.Present domestic powder press, the three beam four-column type structures that adopt more, the rigidity of this structure is poor, being easy to generate tension in process of production makes equipment produce distortion, particularly equipment will produce bigger distortion when the compacting tonnage is big slightly, its machining accuracy can not be guaranteed, thereby can not satisfy the technological requirement of making high-precision part; The shortcoming that exists for the powder press that overcomes this structure, the powder press that adopts tower structure is also arranged in the prior art, but this powder press only is to convert with universal frame type hydraulic press simply, on framework, respectively establishing down an oil cylinder comes the mould of centre exerted pressure and makes wherein powder forming, the powder press of this repacking is not considered the compacting characteristics of powder part, its compacting pattern is identical with the pattern of common hydraulic press, can only be applicable to the individual layer mould preferably, be used for the better simply powder part of shaping form, and for many table tops powder part of shape more complicated, the as above part of two times three table tops, adopt the mould of individual layer to adorn powder according to the final shaping position of part, can not produce different filling amounts according to the difference of each several part structure and exert pressure according to actual pine dress beguine, the parts density of being suppressed is even inadequately, poor-performing can not satisfy requirements of actual production.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, but provide a kind of rational in infrastructure, rigidity is big, stretcher strain is little, the pretension frame-type precision form powder press of many table tops part of the high shaping form complexity of machining accuracy.
Purpose of the present invention is achieved through the following technical solutions: this pretension frame-type precision form powder press comprises closed frame fuselage, master cylinder assembly, end cylinder component, master cylinder assembly is installed in the top of closed frame fuselage, the cylinder component relative bottom that is installed in the closed frame fuselage in the end with master cylinder assembly, it is characterized in that described master cylinder assembly comprises master cylinder, nested oil cylinder, nested oil cylinder is fixedly connected on the piston rod end of master cylinder.
Described master cylinder is fixedly installed on the closed frame fuselage, and described nested oil cylinder is fixedly installed on the slide block that is connected with the closed frame sliding machine body.
Described nested oil cylinder also can comprise the nested oil cylinder of next stage, and the nested oil cylinder of next stage is fixedly connected on the piston rod end of nested oil cylinder.
Cylinder component of the described end comprises end oil cylinder, the nested oil cylinder in bottom, and the nested oil cylinder in bottom is fixedly connected on the piston rod end of end oil cylinder; The nested oil cylinder in bottom is mainly used in the powder part of processing belt centre bore.
Described closed frame fuselage comprises entablature, column, base, and entablature is fixedly connected on the column upper end, and base is fixedly connected on column lower end.
Described closed frame fuselage also includes pull bar, and pull bar passes column, and the two ends attaching nut comes the whole closed frame fuselage of pretension.
Action principle of the present invention is: the master cylinder assembly on this pretension frame-type precision form powder press is provided with multistage compacting oil cylinder, can distinguish drive multilayer template, table top to the differing heights of powder part is suppressed respectively, thereby the present invention can only rely on equipment just to suppress the complex parts with two or more table tops and guarantee that the density of each several part is even, and is functional; Simultaneously, cooperate multilayer mould bases, just can suppress the complicated precision powder part that density goes up many table tops (as above two times three table tops) uniformly for different part otherwise designed; The nested oil cylinder in bottom of this powder press end cylinder setting is mainly used in the centre bore that drives the core bar formation of parts in the mould bases, forms the powder part of centre bore; The closed frame fuselage of this powder press adopts the general frame structure, use the pull bar pretension, its objective is by pull bar general frame imposed load in advance, make it in working order down, the fuselage uprights divides suffered tension corresponding reduction, the rigidity of fuselage is increased, and strain reduces, for the high-precision requirement of compacted part is given security.
The present invention has following advantage and effect with respect to prior art: but this pretension frame-type precision form powder press is rational in infrastructure, rigidity is big, stretcher strain is little, many table tops part of the high shaping form complexity of machining accuracy and the part that reaches the band centre bore, widely applicable; This pretension frame-type precision form powder press can be according to the processing request of the different piece of different parts and compacting respectively, and institute's processed powders part each several part density is even, and is functional.
