Abstract
The utility model discloses a suppression device of powder forming spare with cross bore, including last die, down die, bed die and horizontal plug, go up die and die down respectively from the top of bed die and die cavity matched together that can reciprocate and the bed die down, go up die and die down with form the suppression cavity of powder forming spare between the die cavity, horizontal plug is followed one side cross -under of bed die and is run through along the horizontal direction the suppression cavity is pegged graft at the opposite side of bed die. The mode of setting up the stamping has also been evaded to its mode of avoiding follow -up machining cross bore, can realize that it takes shape to accomplish the cross bore simultaneously among powder compacting forming process, can realize the serialization production operation, the effectual production efficiency that has improved.
Description
Technical field
The utility model relates to powder compacting apparatus technical field, especially relates to the pressure setting of the powder forming part with cross-drilled hole.
Background technology
Powder pressing is shaped also referred to as stamping of powder, and be a large amount of manufacturing process adopted during powder metallurgy is produced, its importance is only second to sintering.Namely die forming is metal dust or powder mixture are loaded in former, and pressurizeed to powder by stamping, after release, pressed compact is deviate from former, completes forming process, and technical process comprises dress powder, swaging, the demoulding and reset.At present, this adopts moulding technology to produce when having the powder forming part of cross-drilled hole, and normally after sintering goods into, then carry out machining and obtain cross-drilled hole, but sintered article has hole, machining property is poor, and working (machining) efficiency is low, and production cost waste greatly.Also there is the method adopting horizontally set stamping, but easily cause compressing product to be out of shape and the phenomenon of cracking, and air pressure or oil gear need be increased, additionally increase considerably manufacturing cost and intelligence makes difficulty.
Utility model content
The utility model is for the deficiencies in the prior art, technical problem to be solved is to provide a kind of pressure setting with the powder forming part of cross-drilled hole, it avoids subsequent mechanical to process the mode of cross-drilled hole, also the mode of setting up stamping has been evaded, can realize in a powder pressing process, completing cross-drilled hole to be shaped simultaneously, continuous prodution operation can be realized, effectively raise production efficiency.
The utility model makes above-mentioned technical problem be solved by the following technical programs.
There is the pressure setting of the powder forming part of cross-drilled hole, comprise upper trimming die, lower punch die, former and horizontal plug, upper trimming die and lower punch die be the die cavity matched together with former moving up and down above and below former respectively, upper trimming die and form the compacting cavity of powder forming part between lower punch die and described die cavity, horizontal plug runs through from the side cross-under of former the opposite side that described compacting cavity is plugged on former in the horizontal direction.By setting up horizontal plug, after powder is filled, upper and lower mould is rushed in capable compressing, and after then extracting horizontal plug, the powder compaction part that the demoulding goes out just has cross-drilled hole, and this manufacturing process is easy and simple to handle, and producting process difficulty is little, is easy to realize.Be convenient to continuous prodution operation, production efficiency is high.
As preferably, the vertical section ovalize of horizontal plug or Long Circle.Carry out in the process sintered after compressing, easily cause cross-drilled hole extensional in the horizontal direction, and in vertical direction contraction distortion, in order to prevent being out of shape the scale error that the impact brought causes cross-drilled hole, preferably the vertical section of horizontal plug is arranged to ellipse or the Long Circle of predetermined value, in sintering warpage, cross-drilled hole reverts to high-precision circle voluntarily afterwards.
As preferably, horizontal plug comprises inserting section, cross-drilled hole shaped segment and section of excessively interting, and cross-drilled hole shaped segment runs through described compacting cavity.As improvement, the side of former arranges the via hole with excessively interspersed section matched in clearance, and the opposite side of former arranges the blind hole with inserting section matched in clearance.
As preferably, the die cavity of former is step-like, and described die cavity comprises the tubular die cavity of the tubular die cavity on top, middle compacting cavity and bottom.As improvement, the diameter of the tubular die cavity of bottom is less than the diameter of the tubular die cavity on top.
The beneficial effects of the utility model:
1. optimize structure, by setting up horizontal plug, simple achieving in a powder pressing process completes the action that cross-drilled hole is shaped simultaneously, can carry out continuous prodution operation, improve production efficiency and product qualified rate.
2. simple and compact for structure, be easy to make, technology difficulty is low, and the quality of production is reliable and stable, reduces production cost, for enterprise adds economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-upper trimming die, punch die under 2-, 3-former, the horizontal plug of 4-, 5-inserting section, 6-cross-drilled hole shaped segment, the excessively interspersed section of 7-.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in detail below by embodiment.
The utility model as shown in Figure 1 has the pressure setting of the powder forming part of cross-drilled hole, comprises upper trimming die 1, lower punch die 2, former 3 and horizontal plug 4.Upper trimming die 1 and lower punch die 2 be the die cavity matched together with former 3 moving up and down above and below former 3 respectively, upper trimming die 1 and form the compacting cavity of powder forming part between lower punch die 2 and described die cavity.Horizontal plug 4 runs through from the side cross-under of former 3 opposite side that described compacting cavity is plugged on former 3 in the horizontal direction.
As a kind of embodiment, horizontal plug 4 comprises inserting section 5, cross-drilled hole shaped segment 6 and section 7 of excessively interting, and cross-drilled hole shaped segment 6 runs through described compacting cavity.Arrange the via hole with excessively interspersed section 7 matched in clearance in the side of former 3, the opposite side of former 3 arranges the blind hole with inserting section 5 matched in clearance.In order to prevent being out of shape the scale error that the impact brought causes cross-drilled hole, ellipse or the Long Circle of the vertical section of horizontal plug 4 being arranged to predetermined value can be selected.
As a kind of embodiment, the die cavity of former 3 is step-like, and described die cavity comprises the tubular die cavity of the tubular die cavity on top, middle compacting cavity and bottom.Eject powder forming part for the ease of lower punch die 2 moves, the diameter of the tubular die cavity being arranged to the diameter of the tubular die cavity of bottom to be less than top can be selected.
The utility model is not limited to above-described embodiment; the embodiment of other malformation that equivalence is replaced in the middle of the known technology that the contour structures of upper trimming die, lower punch die, former and horizontal plug and connected mode each other also can adopt those skilled in the art to obtain or prior art; as long as belong to technical conceive of the present utility model or spirit; by setting up horizontal plug, realizing completing in a powder pressing process embodiment that cross-drilled hole is configured as object simultaneously and all dropping in protection domain of the present utility model.
