Abstract
The invention relates to the field of machining, in particular to a one-step forming mold and forming method of multi-step powdered metallurgy parts. A first lower punch, a second lower punch and a female mold synchronously ascend for powder containing, after powder containing is finished, a first upper punch and a second upper punch descend and then descend synchronously with the female mold, the first lower punch and the second lower punch stop descending after reaching the forming position, compaction forming is finished after the first upper punch and the second upper punch reach the forming position, and then the female mold, the first lower punch and the second lower punch continue to descend to the upper surface of a third lower punch for compaction demolding. The one-step forming mold and forming method of multi-step powdered metallurgy parts have the advantages that powdered metallurgy parts with large axial height, multiple steps and inner type vertical grooves of a certain depth can be formed in one step, the manufacturing cost is lowered greatly, and production efficiency is improved.
Description
Technical field
The present invention relates to field of machining, relate in particular to many steps powdered metal parts one-time-shaped mould and forming method.
Background technology
PM technique is a kind of novel technique, the features such as it has, and cost is low, efficiency is high, complex-shaped, few cutting.At present, for many steps product as shown in Figure 2, traditional method is to make as shown in Figure 1, so causes: 1, Mold Making difficulty: because former height overall is long, bottom punch height overall is long; 2, product processing capacity is large.Below all will greatly increase manufacturing cost, reduce production efficiency, the advantage of PM technique cannot be given full play to.
Summary of the invention
The object of invention: in order to provide a kind of making rapid, process easy many steps powdered metal parts one-time-shaped mould and forming method, specific purposes are shown in a plurality of essence technique effects of concrete implementation section.
In order to reach as above object, the present invention takes following technical scheme:
Scheme one:
Many steps powdered metal parts one-time-shaped mould, it is characterized in that, comprise upper punch one, upper punch two, bottom punch one, bottom punch two, bottom punch three, former, female mould forming product both-side opening groove with both shoulders, corresponding each step surface of moulding of each stamping, described upper punch two is placed in upper punch one middle part, and upper punch two and upper punch one are placed in the mesopore of former; There is bottom punch one below of the mesopore of described former, and bottom punch one below, middle part has bottom punch two, bottom punch two belows to have bottom punch three.
Scheme two:
Many steps powdered metal parts one-step moulding method, it is characterized in that, utilize mould as above, comprise following steps, bottom punch one, bottom punch two and the former dress powder that synchronously rises, after dress powder, upper punch one and upper punch two decline and then synchronously decline with former, bottom punch one, bottom punch two stop declining after reaching shaping position, upper punch one and upper punch two complete pressed compact moulding after reaching shaping position, and then former, bottom punch one, bottom punch two continue to come downwards to the bottom punch three upper surface position pressed compact demouldings.
Adopt as above the present invention of technical scheme, with respect to prior art, have following beneficial effect: can one-shot forming go out that axial height is large, step many and certain depth in type vertical slot powdered metal parts, greatly reduce manufacturing cost, enhance productivity.
Accompanying drawing explanation
In order to further illustrate the present invention, below in conjunction with accompanying drawing, further describe:
Fig. 1 is the structure that background technology of the present invention is produced;
Fig. 2 is the structure that the present invention produces;
Fig. 3 is the model structure that the present invention produces;
Fig. 4 is the structure of former;
1A upper punch one, 2A upper punch two, 1B bottom punch one, 2B bottom punch two, 3B bottom punch three, 4 formers.
The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described, embodiment is not construed as limiting the invention:
Scheme one:
Many steps powdered metal parts one-time-shaped mould, it is characterized in that, comprise upper punch one 1A, upper punch two 2A, bottom punch one 1B, bottom punch two 2B, bottom punch three 3B, former 4, former 4 shaped article both-side opening grooves with both shoulders, corresponding each step surface of moulding of each stamping, described upper punch two 2A are placed in upper punch one 1A middle part, and upper punch two 2A and upper punch one 1A are placed in the mesopore of former 4; There is bottom punch one 1B the below of the mesopore of described former 4, and bottom punch one below, 1B middle part has bottom punch two 2B, bottom punch two 2B belows to have bottom punch three 3B.
With reference to figure 1, due to the restriction of press function and mould structure, compacting powdered metal parts does not out have step, need to could realize through follow-up machined, wastes time and energy, and is unfavorable for the needs of large-scale production.
With reference to accompanying drawing 2, the part of straight forming of the present invention has open slot and each step.
With reference to accompanying drawing 3, a kind of mould of powder metallurgy, its structure comprises the female mould forming product both-side opening groove with both shoulders, corresponding each step surface of moulding of each stamping.
Use the working method of the metallurgical part of pressed powder of the present invention to be: to utilize mould as above, comprise following steps, bottom punch one, bottom punch two and the former dress powder that synchronously rises, after dress powder, upper punch one and upper punch two decline and then synchronously decline with former, bottom punch one, bottom punch two stop declining after reaching shaping position, upper punch one and upper punch two complete pressed compact moulding after reaching shaping position, and then former, bottom punch one, bottom punch two continue to come downwards to the bottom punch three upper surface position pressed compact demouldings.
With reference to accompanying drawing 2, the part of straight forming of the present invention has open slot and each step.
The present invention makes corresponding former and upper and lower stamping according to the part step of required compacting and open slot, makes part by one-step compressing.
more than show and described basic principle of the present invention, principal character and advantage of the present invention.Those skilled in the art should understand the present invention and not be restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in claimed scope.
