Description
Technical field
The invention belongs to the machine components making apparatus, relate in particular to a kind of device of making helical discharging sedimentation centrifuge helical blade.
Background technology
The extensive use horizontal spiral discharge sedimentation centrifuge carries out Separation of Solid and Liquid in fields such as industries such as food, medicine, chemical industry and wastewater treatment at present.Spiral is one of major part of centrifuge, the production capacity of centrifuge and lead of screw and spiral head number direct ratio, and pitch is big more, and the ability that moves of many promotions material is big more more for spiral head number, and speed is fast more, and production capacity is high more.Therefore, its helical blade broad of the centrifuge that production capacity is big, diameter are big, lead angle is big, thicker its complex manufacturing technology of blade wall thickness.Can adopt the mould compacting, need prefabricated mould, acquire large pressing machine, and need to adopt hot-pressing technique compacting blade, thereby manufacturing cost is very high.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, a kind of device of making helical discharging sedimentation centrifuge helical blade to be provided, and it has the advantages that manufacture craft is simple, easy to operate, processing cost is low.
The present invention for achieving the above object, be achieved through the following technical solutions: a kind of device of making helical discharging sedimentation centrifuge helical blade, it is characterized in that: mainly by base plate, several vertically disposed slideways, the spiral tube, central shaft, leading screw, fork, pressing plate, depression bar and backing plate are formed, described spiral tube lower end and base plate are affixed, spiral tube circumference is provided with some shape elongated slots that rise in the shape of a spiral, central shaft is located at spiral tube center and affixed with base plate, one end of described fork is provided with axle sleeve, axle sleeve and central shaft axle are slidingly connected, the fork other end is bolted with leading screw, leading screw one end and pressing plate touch, described slideway upper edge is axially arranged with the elongated slot of grafting depression bar, described elongated slot height is corresponding with elongated slot on being located at spiral tube circumference, and described backing plate places on the base plate.
Described spiral tube is a hollow shape, and the upper end is provided with mutually perpendicular central shaft supporting gusset in its chamber.

Beneficial effect of the present invention: it has the advantages that manufacture craft is simple, easy to operate, processing cost is low.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2-the 5th, the process schematic diagram of processing helical blade.
The specific embodiment
In conjunction with preferred embodiment, to details are as follows according to the specific embodiment provided by the invention.
See accompanying drawing 1 for details, a kind of device of making helical discharging sedimentation centrifuge helical blade, mainly by base plate 1, four slideways 2 perpendicular to the base plate setting, spiral tube 3, central shaft 4, leading screw 5, fork 6, pressing plate 7, depression bar 9 and backing plate 10 are formed, described spiral tube lower end and base plate are affixed, spiral tube circumference is provided with four shape elongated slots 11 that rise in the shape of a spiral, elongated slot is provided with every 90 degree, central shaft is located at spiral tube center and affixed with base plate, one end of described fork is provided with axle sleeve, axle sleeve and central shaft axle are slidingly connected, for preventing the fork axial float, fastening with nut 12, the fork other end is bolted with leading screw, and leading screw one end and pressing plate touch, it is corresponding with elongated slot on being located at spiral tube circumference to be axially arranged with the described elongated slot height of elongated slot 11-1 of grafting depression bar on the described slideway, and described backing plate places on the base plate.Described spiral tube is a hollow shape, and the upper end is provided with mutually perpendicular central shaft supporting gusset 13 in its chamber.
Operation principle: see Fig. 2-Fig. 5 for details, when making helical blade, in helical blade 8, the prefabricated annular of outside dimension has the helical blade blank of otch, one end that will have the blank flat of otch places on the backing plate, push down and compress depression bar 9 with depression bar 9 with leading screw 5, with several very heavy 14 overheads in the below of blank flat, by spiralling direction, at any time adjust the position of jack, when blank flat progressively being pushed up the position of each slideway fluting with jack, one by one each depression bar is inserted in each slide groove, when the other end of annulus blank flat otch has risen a pitch, pressing plate is inserted elongated slot to be pressed in the upper end of helical blade and to use the leading screw clamping platen, knock helical blade with iron hammer again and make it discharge stress, a helical blade has just been made.After using this device, the manufacturing speed of helical blade and quality have all had large increase.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
