Technical field
The present invention relates to field of powder metallurgy, prepared by the powder metallurgy of especially a kind of cylindrical parts.
Background technology
Powder metallurgy is a kind of preparation method being highly useful and commonly using in part manufacture. Powder metallurgy is to produce metal or with metal dust as raw material, through shaping and sintering, manufactures the Technology of metal material, composite and all kinds goods. Due to the advantage of PM technique, it becomes the key solving new material problem, plays very important effect in the development of new material.
But, the feature that the sintering process in powdered metal parts preparation process has time length, power consumption is high. Therefore, the preparation of powdered metal parts had restriction. Prepared by the part particularly with straight-lined manufacturing, the preparation of the part that volume is little and quantity is many, and its restriction is particularly evident.
If adopting multiple parts batch to sinter, a large amount of part buildup and follow-up equipment can be made to leave unused; The number of parts easily causing online production increases, and increases carrying cost.
Summary of the invention
It is an object of the invention to provide powder metallurgy preparation system, it can carry out continuous-flow type production for the column class part of production line balance, it is to avoid a large amount of part buildup on a production line, reduce the online circulation time of part as far as possible. And make part blanks steady in the process entering sintering furnace and leave sintering furnace.
The technical solution used in the present invention is as follows:

Described feed zone includes rewinding mouth from top to bottom successively, cofferdam on first, cofferdam on cofferdam and the 3rd on second.
Described discharging section includes first time cofferdam, second time cofferdam, the 3rd time cofferdam and rewinding mouth from top to bottom successively.
Described blank forming device includes cope match-plate pattern and lower bolster, is provided with mould molding body, is provided with die cavity in the middle of mould molding body between cope match-plate pattern and lower bolster; The centre of cope match-plate pattern is provided with the through hole connected with described die cavity, pressure plunger can stretch in described die cavity by described through hole, the pressurization head of pressure plunger is corner ends, described corner ends has the angle angle equal to described base substrate passage with horizontal direction of clinoplain, described clinoplain and vertical direction; The clinoplain of described corner ends also coordinates matchingly and removedly with the clinoplain of upper dihedral cushion block, and the upper side of described upper dihedral cushion block is its clinoplain, and downside is horizontal plane; The inside bottom of described die cavity is further fixedly arranged on non-movable piston, the downside of described non-movable piston is fixing with described lower bolster to be connected, upper side is clinoplain, and the angle of the clinoplain of described non-movable piston and vertical direction is equal to the angle of described base substrate passage with horizontal direction; The clinoplain of described non-movable piston also coordinates matchingly and removedly with the clinoplain of lower dihedral cushion block, and the downside of described lower dihedral cushion block is its clinoplain, and upper side is horizontal plane; Thereby, it is possible to form blank forming chamber on described between downside and the upper side of lower dihedral cushion block of dihedral cushion block.
The base substrate formed in the described blank forming chamber of described blank forming device one by one can be entered by cofferdam on described in the sintering stage of described sintering equipment and be sintered, and one by one can leave described sintering equipment by described lower cofferdam after sintering completes.
Pass through such scheme, due to while sintered part(s), the powdered metal parts base substrate of upstream subsequent production can step into sintering furnace by entrance passage, while not affecting the part sintered, enable to the up-to-date base substrate produced entrance sintering furnace and proceed by sintering, therefore, decrease the holdup time of base substrate to greatest extent, decrease the carrying cost of production line. And, continuously, speed produce sintered part(s) equably, also make follow-up downstream produce equipment and decrease the vacant time as far as possible, improve the utilization ratio of equipment, fully employ the depreciable cost of equipment. The sintering stage at center is entered and by the eccentric sintering stage of cabin section one by one, it is possible to do not affect to greatest extent and burning part by cabin section one by one.
And, by the blank forming device of the present invention, which form the parallel inclined ramp at two ends, it is possible to coordinate with the ground of cabin section, thus when entering sintering furnace and leaving sintering furnace with cabin section smooth co-operation, reduce friction and scratch.
