Description
Technical field
The present invention relates to a kind of polytetrafluoroethylene (PTFE) profiled piece when powder is shaping, how to carry out trace add control device, especially relate to 4mm with the suspension powder polytetrafluoroethylene (PTFE) of lower impressions the opposite sex part shaping time micro-adding device.
Background technology
Polytetrafluoroethylene (PTFE) profiled piece compressing, within a very long time, complete by hand, main difficulty is that the cavity positions being less than 4mm when volumetric method adds powder not easily adds powder, because the feature of polytetrafluoroethylene (PTFE) not easily flows, be easy to occur to block arch camber when adding powder by hand and be commonly called as " arch bridge " phenomenon; Some the powder forming machines occurred on the market now; the cavity positions only larger to position when reality uses; the effect had; and for being less than the cavity positions of 4mm; or during the darker die cavity in position; then often there is powder " arch bridge " phenomenon, thus cause compressing product density uneven. these powder forming machines have significant limitation in use, can not meet the needs that enterprise scale is produced.
Summary of the invention
In order to overcome the above-mentioned defect of existing powder forming machine; the invention provides a kind of suspension powder polytetrafluoroethylene (PTFE) profiled piece shaping time micro-adding device; the difficult problem that during to solve polytetrafluoroethylene (PTFE) profiled piece compressing, product density is uneven, meets the needs that enterprise scale is produced.
For solving its technical problem, the technical solution used in the present invention is: design shaping for polytetrafluoroethylene (PTFE) profiled piece time adding set, comprise the B of fixing core rod, C, E tri-fixed heads, its feature is: with B, C, E tri-templates fix core bar, on intermediate die plate C, fix the cylinder D of two pieces range-adjustable simultaneously, these three templates, two rhizoid bars connect together, spring supporting is used between template. screw mandrel and intermediate die plate nut maintain static, two-piece template can be movable, and with clamp nut control activity height, isolate with spring between three plates, and be connected with screw rod.Like this, just can regulate die cavity according to the apparent density of powder, and fix with nut. during dress powder, moved up and down, pull a fixed head by cylinder, the die cavity position that the core bar that the solid public plate of another two pieces just can be made to fix controls repeatedly fully adds powder.
Wherein, middle C plate is crucial, and it can have core bar to fix, also can be empty, and its main purpose is moving up and down by the control C plate that moves up and down of cylinder D;
If profiled piece product does not require that C plate controls die core rod, then can with the little solid public plate transition of fixing core bar, can the stability of assurance device, the little solid public plate controlling core bar matches with the circular hole of device, and fixes from the side with screw;
If the core bar thickness that mold cavity requires or diameter are less than 4mm, then the little solid guide pillar of public plate 8mm coordinates with the solid public plate of upper level, ensures its stability;
The little solid public plate of each core bar is fixed, and little solid public plate is outer through matching with the circular hole position of device, and each little solid public plate will divide two-stage, and one-level coordinates, and another level will play step, puts and only loosen;
In order to the speed of assurance device, must link closely with extension spring and G plate in E plate both sides, made this device returning quickly after the material returned;
This powder device that adds in reality manufactures, also to consider powder pressing shaping after material returned problem. so be provided with push pedal push rod in a device, and two follow block screws;
This device only relates to micro-adding portion, does not relate to and how to suppress and how to manufacture complete machine structure.
Compared with prior art, the beneficial effect of the technical program is: narrow die cavity position repeatedly can add powder from the bottom up, with the adding powder amount and can not have any different of other spacious positions. ensure that the powder apparent density at each position of die cavity is the same, thus ensure the uniformity of product density.Actual effect clearly.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further described:
Fig. 1 is overall structure schematic diagram of the present invention:
In figure, each label declaration: A is the fixed head of fixing die, B, C, E are the fixed head of fixing core bar, D is increased stroke-adjustable gas cylinder, and F, K are the base of the adjustment height of working in coordination, and G is device pedestal, M is two equally long optical axises, H is the push pedal of de-material, and I is that cylinder core bar and B plate are fixedly connected nut, and J is spring (altogether 6), L is four isometric optical axises, and N is for tightening up screw mandrel.
Detailed description of the invention
Design shaping for polytetrafluoroethylene (PTFE) profiled piece time adding set, comprise the B of fixing core rod, C, E tri-fixed heads, its feature is: fix core bar with these three template B, C and E, on intermediate die plate C, fix the cylinder D of two pieces range-adjustable simultaneously, these three templates two rhizoid bar N connect together, support between template with spring J. and screw mandrel and intermediate die plate C nut maintain static, two-piece template B, E can be movable, and with clamp nut control activity height, B, C, with spring J isolation between E tri-plates, and be connected with screw rod.Like this, just can regulate die cavity according to the apparent density of powder, and fix with nut. during dress powder, moved up and down, pull B fixed head by cylinder, like this, the die cavity position that the core bar that solid public plate C, E just can be made to fix controls repeatedly fully adds powder;
Wherein, middle C plate is crucial, and it can have core bar to fix, also can be empty, and its main purpose is moving up and down by the control C plate that moves up and down of cylinder D;
If profiled piece product does not require that C plate controls die core rod, then can with the little solid public plate transition of fixing core bar, can the stability of assurance device, the little solid public plate controlling core bar matches with the circular hole of device, and fixes from the side with screw.
During use, if the core bar thickness of mold cavity requirement or diameter are less than 4mm, then the little solid guide pillar of public plate 8mm coordinates with the solid public plate of upper level, ensures its stability; The little solid public plate of each core bar is fixed, and little solid public plate is outer through matching with the circular hole position of device, and each little solid public plate will divide two-stage, and one-level coordinates, and another level will play step; This powder device that adds in reality manufactures, also to consider powder pressing shaping after material returned problem. so be provided with push pedal push rod H in a device, and two follow block screws.
As the preferred concrete structure of one, the device that trace when suspension powder polytetrafluoroethylene profiled piece is shaping adds, comprises and how to build different die cavities, and how accurately control repeatedly adds powder two parts; Build different die cavities, the main two pieces cylinder leaning on the floating of spring and range-adjustable, also has the pedestal of adjustment height, is tightened up after mixing up by nut, and each solid public plate is fixed by the screw of side; Before adding powder, cylinder D locks, and after adding first time powder, cylinder D loosens, and adds the 2nd powder; If after second time adds powder, find that some position adds powder inadequate, can above-mentioned action be remake once,
Whole device is controlled by mechanical part and PLC two parts and is coordinated.
