Description
Technical field
This utility model relates to powder hydraulic press field, particularly to a kind of powder compaction presses
Feed box.
Background technology
Powder metallurgy is to produce metal or with metal dust (or metal dust and the mixture of non-metal powder) as former
Material, again by sintering after having pressure or shaping without pressure, manufactures metal material, the compound and technique skill of all kinds goods
Art.
It is a series of excellent that PM technique possesses the most energy-conservation, province's material, excellent performance, Product Precision height and good stability etc.
Point, is very suitable for producing in enormous quantities.At present, PM technique has been widely used in traffic, machinery, electronics, aviation boat
My god, the field such as weapons, biology, new forms of energy, information and nuclear industry, become most development vitality in new material science branch it
One.
Along with developing rapidly of domestic powder technology, many metal materials all use powder compacting technology, i.e. pass through powder
Metal dust is pressed into pie by moulding press, then prepares metallic article by sintering.The feeding device of powder compaction presses
During work, negative template being provided with delivery sheet, feed box is driven movable by the feeding cylinder being arranged on delivery sheet tail end so that
Powder in feed box falls in the former of lower section.At present during the charging of tradition powder feeder, owing to needs are on delivery sheet
Move back and forth, rub for a long time between feed box and delivery sheet, often result in leakage powder, cause the phenomenon that mould feeding quantity is inaccurate, meeting
Have a strong impact on the quality of product；I.e. need the magazine more renewed after leakage powder occurs, not only increase production cost, also have impact on life
Produce efficiency.
Therefore, research and development one can improve product quality and production efficiency, and can reduce raw
The powder compaction presses feed box producing cost is necessary.
Utility model content
The technical problems to be solved in the utility model is to provide one can improve product quality and production efficiency, and can drop
The powder compaction presses feed box of low production cost.
For solving above-mentioned technical problem, the technical solution of the utility model is: a kind of powder forming feeding hydraulic press feeding
Box, including a pair former, the outside of described former is respectively connected with negative template, and connecting in the outer end of a described negative template has a level
Delivery sheet, described delivery sheet is provided with a cylinder driven in the horizontal direction, and there is feed box inner connection of cylinder, its innovation
Point is: described feed box includes that a wool felt backing plate, described wool felt backing plate center have a manhole, at Pilus Caprae seu Ovis felt pan
A centrally disposed square box of plate, described square box is spliced by the riser that four block sizes are identical, and described just
The length of side of cube box is more than the diameter of manhole；Described wool felt backing plate lower surface be symmetrically arranged on two with politef
Bar, connects at the center, lower surface of wool felt backing plate and has a politef pressure ring, and the diameter of described pressure ring is more than manhole
Diameter；The also liner one polyurethane annular protrusion at the center of pressure ring, the diameter of polyurethane annular protrusion is slightly larger than manhole
Diameter.
Further, the height of described politef pressure ring is identical with the height of politef bar.
The utility model has the advantage of: powder forming feeding hydraulic press feed box of the present utility model, at Pilus Caprae seu Ovis felt pan
Politef bar is set up in the both sides of plate lower surface, thus adds the sealing with delivery sheet；Lower end at wool felt backing plate
Center, face connects a politef pressure ring, and the also liner one polyurethane annular protrusion at the center of pressure ring, and annular protrusion is
In order to increase the sealing with pressure ring, annular protrusion uses polyurethane simultaneously, the most wear-resisting；The design of this structure so that send
Magazine will not cause Lou powder and the inaccurate phenomenon of feeding quantity because rubbing for a long time between feed box and delivery sheet, thus improve
The quality of product；Additionally, also without the magazine more renewed, not only reduce production cost, also improve production efficiency.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the front view of this utility model powder forming feeding hydraulic press feed box.
Fig. 2 is the side view of this utility model powder forming feeding hydraulic press feed box.

Fig. 4 is the upward view of this utility model powder forming feeding hydraulic press feed box.
Detailed description of the invention
The following examples can make professional and technical personnel that this utility model is more fully understood, but the most therefore will
This utility model is limited among described scope of embodiments.
The powder forming feeding hydraulic press feed box of the present embodiment, including a pair former, the outside of former is respectively connected with the moon
Template, connects in the outer end of a negative template and has a straight feeding plate, this delivery sheet is provided with the gas driven in the horizontal direction
Cylinder, has feed box inner connection of cylinder.
As shown in Fig. 1,2,3 and 4, it is circular that this feed box includes that a wool felt backing plate 1, wool felt backing plate 1 center have one
Through hole 2, at a centrally disposed square box 3 of wool felt backing plate 1, this square box 3 is by the identical riser of four block sizes
It is spliced, and the length of side of square box 3 is more than the diameter of manhole 2；
Wool felt backing plate 1 lower surface be symmetrically arranged on two with politef bar 4, in the lower surface of wool felt backing plate 1
The heart connects a politef pressure ring 5, and the diameter of this pressure ring 5 is more than the diameter of manhole 2；The center of pressure ring 5 also in
Serving as a contrast a polyurethane annular protrusion 6, the diameter of polyurethane annular protrusion 6 is slightly larger than the diameter of manhole 2.
The powder forming feeding hydraulic press feed box of the present embodiment, sets up polytetrafluoro in the both sides of wool felt backing plate lower surface
Ethylene bar, thus add the sealing with delivery sheet；Connect at the center, lower surface of wool felt backing plate and have a politef
Pressure ring, and the also liner one polyurethane annular protrusion at the center of pressure ring, annular protrusion is to increase the sealing with pressure ring, with
Time annular protrusion use polyurethane, relatively more wear-resisting；The design of this structure so that feed box will not because of feed box and delivery sheet it
Between rub for a long time, cause Lou powder and the inaccurate phenomenon of feeding quantity, thus improve the quality of product；Additionally, also without more
The magazine renewed, not only reduces production cost, also improves production efficiency.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.This
