Abstract
The utility model relates to a kind of one-mold multiple-member powder metal pressure-equalizing device, comprise the cope match-plate pattern, negative template, the fixed head that set gradually from top to bottom, negative template is provided with former, this former has several powder metal die cavities, cope match-plate pattern is provided with some upper punches corresponding with this powder metal die cavity; Fixed head is arranged some undershoots corresponding with powder metal die cavity; Its innovative point is: be provided with pressure-equalizing device between described fixed head and each undershoot, be specially: fixed head is provided with several hydraulic cylinders, each hydraulic cylinder is provided with the piston rod corresponding with powder metal die cavity, and the upper end of this piston rod is bolted and is fixed with undershoot; And the cavity of resorption mutual conduction of each hydraulic cylinder.The utility model has the advantage of: when suppressing, utilizing the hydraulic cylinder of mutual conduction to carry out the automatic adjustment of hydraulic oil liquid, making the pressure balance of each undershoot, density area when guaranteeing each product shaping is consistent, greatly improves product percent of pass.
Description
Technical field
The utility model relates to a kind of powder metal mould bases, particularly a kind of one-mold multiple-member powder metal pressure-equalizing device.
Background technology
Along with the develop rapidly of domestic powder technology, many metal materials all adopt powder compacting technology, namely by powder shaping press, metal dust are pressed into pie, then by the obtained metallic article of sintering.
Pulverulent product, when compressing, for increasing work efficiency, usually adopts the pressing mode of one-mold multiple-member, i.e. the negative template of press arranges several formers, and each former is equipped with a upper punch and undershoot realizes compacting.The shortcoming of this kind of structure is: because each powder box is to adding powder amount and cannot accomplish completely the same in former, and upper and lower punching synchronously drives by a top shoe, sliding block when suppressing, therefore the product density otherness after compacting is larger, therefore, when the pulverulent product compacting higher for density requirements, qualification rate is very low.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of one-mold multiple-member powder metal pressure-equalizing device, can improve product density uniformity, rate of reducing the number of rejects and seconds.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of one-mold multiple-member powder metal pressure-equalizing device, comprise the cope match-plate pattern, negative template, the fixed head that set gradually from top to bottom, negative template is provided with former, this former has several powder metal die cavities, cope match-plate pattern is provided with some upper punches corresponding with this powder metal die cavity; Fixed head is arranged some undershoots corresponding with powder metal die cavity; Its innovative point is: be provided with pressure-equalizing device between described fixed head and each undershoot, be specially: described fixed head is provided with several hydraulic cylinders, each hydraulic cylinder is provided with the piston rod corresponding with powder metal die cavity, and the upper end of this piston rod is bolted and is fixed with undershoot; And the cavity of resorption mutual conduction of described each hydraulic cylinder.
Preferably, the public cylinder body of described each hydraulic cylinder, cylinder body has the hydraulic cavities corresponding with powder metal die cavity, and the piston rod of each hydraulic cylinder is arranged in hydraulic cavities by cylinder mouth flange, and the bottom of cylinder body is drilled with the runner with the conducting of each hydraulic cavities cavity of resorption.
The utility model has the advantage of: when suppressing, utilizing the hydraulic cylinder of mutual conduction to carry out the automatic adjustment of hydraulic oil liquid, making the pressure balance of each undershoot, density area when guaranteeing each product shaping is consistent, greatly improves product percent of pass.
