Description
Technical field
The utility model relates to the automatic press-moulding die of a kind of sintered metal product, the double hole mould of particularly a kind of novel, high accuracy, the automatic compression moulding of high efficiency sintered metal product.
Background technology
When the automatic compression moulding of sintered metal product,, developed a kind of automatic compacting double hole mould in recent years in order to improve compacting efficient.Double hole mould can be suppressed two products each time, its production efficiency is the twice of common die, but because the compression moulding of two products is to finish in a period of motion of forcing press, in order to guarantee each part dimensional accuracy of products, the substance that necessarily requires each part product of suppressing out is with highly consistent, this just requires the height unanimity of one group of low punch in the double hole mould, to guarantee the weight unanimity of product; Also require the height of one group of upper punch in the double hole mould also consistent simultaneously, to guarantee the dimensional accuracy of products unanimity.Now the double hole mould that uses up and down in two groups of drifts in every group the structure of two drifts be all-in-one-piece, the contour of two drifts requires can only the pattern tool to process and guarantees in every group, can not carry out the Height Adjustment of drift in the use.And the difficulty of processing of this monoblock type drift is big, and the more difficult processing of monoblock type drift of complex geometry goods is so influenced applying of double hole mould.In producing use, if having a drift to damage in certain group in this monoblock type drift, in order to guarantee the height unanimity of two drifts, drift that will hold, bad is repaired together during repairing, causes the increase of mould repair cost again.
The utility model content
The purpose of this utility model is exactly the technical problem that exists for the monoblock type drift double hole mould that solves above-mentioned prior art, provide a kind of novel powder automatic compression moulding double hole mould, it is a kind of split type drift double hole mould with wedge block, it can once suppress two products, and the substance Deviation Control that guarantees two products is at ± 0.06g (gram), dimensional discrepancy is controlled at ± 0.04mm (millimeter) scope in, can be widely used in automatic compression moulding various powders metallurgical product.
For realizing that the technical scheme that the purpose of this utility model adopts is:
The automatic compression moulding of powder of the present utility model is adopted the split type punch structure of band wedge block with double hole mould, comprises the upper punch clamper, low punch clamper, and the mould of being made up of two upper punch, two low punches and former.The upper punch clamper comprises that left and right symmetrically is installed in two drift installing plates on its base, adjust wedge blocks for coincide to center plane of symmetry inclined ramp two that are provided with on upper end and the base, pass and be locked in behind the fixing hole on the drift installing plate sidewall of upper punch clamper and adjust the two rhizoid bars that wedge block is threaded, all be provided with a screw that is used for fixing upper punch on the every drift installing plate.The low punch clamper comprises that left and right symmetrically is installed in two travellers on its base, upper end and traveller lower end are provided with, and two of coincideing to center plane of symmetry inclined ramp adjust wedge blocks, pass and are locked in behind the fixing hole on the base side wall of low punch clamper and adjust the two rhizoid bars that wedge block is threaded.Two upper punch pass respectively to be close to adjust on the wedge block lower surface and by screw behind the installing hole corresponding on the drift installing plate and are fixed in the drift installing plate, two low punches are respectively by two half-round clamping rings be enclosed within an outer annulus of two half-round clamping rings and be fixedly connected on the corresponding traveller upper end mount pad, and the working portion of two upper punch and two low punches inserts respectively on the former in symmetrical two die cavities.
The utility model has the advantages that two low punches are connected to two and adjust on the traveller, adjusting traveller for two is connected respectively on two interior adjustment wedge blocks of base again, change the height of low punch by the position of leading screw and nut mechanism adjustment wedge block, can guarantee that two low punches height and position in vertical direction is accurately consistent, thereby guarantee the substance unanimity of two blank products.Two upper punch are assembled to upper punch respectively and adjust on the wedge block lower surface, adjust the wedge block position by leading screw and nut mechanism, can guarantee that also two upper punch height and position in vertical direction is accurately consistent, thereby guarantee the consistent size of two blank products.Simultaneously, each low punch of mould adopts two half-round clamping rings and a form of annular rings to be connected on the corresponding adjustment traveller, each upper punch clamping is on the drift installing plate of correspondence, each drift can be distinguished independently and installs, dismantles, keeps in repair and adjust, operate, process more convenient, can save maintenance, the processing charges of drift, enlarge the range of application of mould.
