The specific embodiment
Below in conjunction with embodiment the utility model is described in further detail, but protection domain of the present utility model is not limited to this.
As Figure 1-3, the utility model relates to a kind of secondary powder device for filling that valve retainer is made that is used for, comprise mould bases 1, operating desk 2, feeding device, die 3 and the upper punch 4 that matches with die 3, described operating desk 2 is located on the mould bases 1, described die 3 is installed on the operating desk 2, described feeding device comprises the first material boots 5, the described first material boots 5 are installed on the mould bases 1, described upper punch 4 is located at directly over the die 3, also be provided with low punch 12 in the described die 3, described feeding device also comprises the second material boots 6 and is used to promote first cylinder 7 of the second material boots 6, the described first material boots, 5 feeding face sides are provided with second cylinder 8 that is used for the valve retainer ejection operation platform 2 that will complete, the described second material boots 6 are installed on the operating desk 2, the described first material boots 5, die 3, the second material boots 6 and first cylinder 7 are in turn in line.
Described secondary powder device for filling comprises also and is used to guarantee that the second material boots 6 press the 3rd cylinder 9 of operating desk 2 that described the 3rd cylinder 9 is located at two sides of the second material boots 6.
Be provided with the gas-liquid conversion equipment 10 that is used to guarantee the second material boots, 6 feeding stabilities in described first cylinder 7.
The bottom of the described first material boots 5 and the second material boots 6 is provided with polytetrafluoroethylene floor.
The described first material boots, 5 front end sidepieces are provided with and are used for and will be continued to push to the scraping wings 11 of a direction by the valve retainer of second cylinder, 8 ejection operation platforms 2.
The utility model specific embodiment is as follows:
At first, die 3 rises, low punch 12 also rises simultaneously, because the stroke that the stroke that low punch 12 rises rises less than die 3, so the time form a space that can be used for feeding in raw material between die 3 and the low punch 12, the first material boots 5 are pushed into the workspace of operating desk 2, carry out first time and feed in raw material, all the other mechanisms stop, and so far the powder in die 3 chambeies is the ground floor powder; When the first material boots 5 withdrawed from the workspace of operating desk 2, die 3 was motionless, and low punch 12 descends, again form the space that can be used for feed in raw material between die 3 and the low punch 12 this moment, this is reinforced for the second time space, and the second material boots 6 begin to enter the workspace of operating desk 2, carries out the second time and feeds in raw material.
After secondary charging finished, finishes the filling of second layer powder, upper punch 4 descended and begins compacted products; After compacting finished, die 3 dropped to demoulding position, product stripping.
Because in twice reinforced process, upper punch 4 keeps motion always, so the time between feeding in raw material for twice is compact, the reinforced for the second time time is also shorter, so in debug process, need adjust the feeding angle according to the pressing speed of upper punch 4.
The utility model has installed second cylinder 8 additional on the first material boots 5, when the demoulding, before the first material boots 5 were pushed into die 3, second cylinder 8 ejected product, and simultaneously, the scraping wings 11 that is contained on the first material boots 5 is released product; When product is released, the filling of beginning ground floor powder, so far, another beginning that circulates.
When the powder feeding of material boots, material boots bottom margin leaks powder easily, so all increased polytetrafluoroethylene floor in the bottom of the first material boots 5 and the second material boots 6;
In the process of the second material boots, 6 feedings, need the assurance second material boots 6 to be close to operating surface and product is met the requirements, so need compress to the second material boots 6 to strike off unnecessary powder.As use spring, because spring is tired easily, pulling force can descend gradually, and fracture easily, so adopted 9 pairs second material boots 6 of symmetrically arranged two the 3rd cylinders to compress;
Stability when improving 6 feedings of the second material boots is gas for 7 one sections so increased a cover gas-liquid conversion equipment 10, the first cylinders, one section is liquid, the flow of this end of liquid is adjustable, controls the speed of the second material boots 6 with this, and makes the operation of the second material boots 6 more steady;
Owing to can wear and tear in material boots bottom, first cylinder 5 has certain angle of oscillation when motion, though this angle is very small, but also can influence the service life of first cylinder 5, so designed the structure that first cylinder 5 can be swung, damaging can not appear because small angle of oscillation is arranged in the piston of guaranteeing first cylinder 5, influences its service life.
The scraping wings 11 of the described first material boots, 5 front end sidepieces can be released continuing after being turned to 90 ° by the valve retainer of second cylinder, 8 ejection operation platforms 2.
The valve retainer diameter that is made via the utility model is identical with the diameter of low punch 12, and valve retainer is divided into fit tightly two-layer up and down, two-layer material is inequality, part time job partly uses powder preferably, but not working portion then uses common powder, under the prerequisite that does not reduce part quality, reduced cost of parts to greatest extent.
