Description

Sand roller cylinder with four-head pitch auger guiding rib

Technical field

It the utility model is related to sand roller, especially a kind of sand roller cylinder with four-head pitch auger guiding rib.

Background technology

Sand roller be casting automatic continuous production during the casting in the casting mold poured and molding sand are divided From equipment, supporting sand roller inner barrel is relatively simple for structure in common sand preparing system, before barrel inside Endfeed mouth has the inner bag of a taper with leakage sand hole, and inner bag is welded with continuous conveyor screw with barrel inwall interlayer Piece, after casting mold enters cylinder, the part sand of roller cast(ing) surface when rotated enters conveyor screw by the leakage sand hole on inner bag It is interior, promoted backward by conveyor screw, casting is slipped into rear class cylinder by the inner bag of taper, and casting is in cylinder by continuous Anti- rolling, casting and the mutual downthrust of casting, to take off the core for being bonded in cast(ing) surface and inner chamber, in pushing away for conveyor screw Roller is skidded off under entering.

Its shortcoming is：When cylinder rotates, casting and sand fully rely on the conveyor screw that is welded on barrel front end inwall to After promote, easily cause casting and sand wash in the middle part of cylinder, collided between roll procedure medium casting than more serious, cause casting Surface is damaged, and has a strong impact on the visual quality of casting, or even causes casting to scrap, and according to statistics, casting damage ratio is up to 30%, in order to keep away Exempt to lose, the casting for having more than half kind can not enter roller, can only take out halfway, waste largely manually, cause molding sand Waste.

Utility model content

The technical problems to be solved in the utility model is：Serious scrap is damaged in order to solve to exist in common casting sand fallout A kind of the problem of more, there is provided sand roller cylinder with four-head pitch auger guiding rib.

Technical scheme is used by the utility model solves its technical problem：It is a kind of with four-head pitch auger guiding rib Sand roller cylinder, has a cylinder, and the front portion in the cylinder has inner bag, and the inwall of the cylinder and the outer wall of inner bag have Interlayer, conveyor screw piece is installed with interlayer, the outside of the cylinder has roller-way, the cylinder inboard wall at the inner bag rear portion On be provided with equidistantly circumferentially continuous rib, at least one of surrounding is provided with the cylinder inboard wall at the rib rear portion and is intermittently welded Four-head pitch guiding rib, the rear portion of the four-head pitch guiding rib is provided with exit cone section.

As preferable, the four-head pitch guiding rib is twist uniformly distributed.

As preferable, it is 8 ° that the four-head pitch guiding rib, which has level inclination α,.

The beneficial effects of the utility model are that the utility model changes on the basis of original sand roller inner barrel structure Make, in the rib that cylinder inner bag rear inner wall surrounding weld horizontal is placed, be uniformly distributed by certain spacing, behind rib Cylinder inboard wall surrounding is intermittently welded four short four-head pitch guiding ribs, prolongs always in certain level inclination along the hand of spiral Exit cone section is extended, the effect of rib drives casting rolling, takes off the core inside casting die cavity, four-head when being cylinder rotation Pitch guiding rib plays a part of shunting, accelerates the gait of march of molding sand and casting, avoids inner barrel molding sand and casting from accumulating, Reduce casting to roll in cylinder the time, and casting is arranged in an orderly manner, slowly skidded off under the propulsion of front end conveyor screw piece Cylinder, so as to reduce mutually collide between casting caused by cast(ing) surface damage, greatly reduce the casting during casting falling sand Part surface is damaged, and avoids waste product caused by damaging；To be transformed by roller, more than 95% kind casting can enter roller knockout, The human cost of midway pickup and the waste of molding sand are saved；Apparatus of load is alleviated, saves power cost；This practicality simultaneously is new Type also has the characteristics of transformation is simple, improvement cost is low, brings notable results, be practical.

Brief description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is sectional view figure of the present utility model.

Fig. 2 is the enlarged drawing at A in the utility model Fig. 1

In figure:1. cylinder, 2. inner bags, 3. conveyor screw pieces, 4. roller-ways, 5. ribs, 6. four-head pitch guiding ribs, 7. outlets Conical section.

Embodiment

The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram, Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.

The sand roller cylinder with four-head pitch auger guiding rib shown in Fig. 1 and Fig. 2, there is cylinder 1, the cylinder 1 Interior front portion has inner bag 2, and the inwall of the cylinder 1 has interlayer with the outer wall of inner bag 2, conveying spiral shell is installed with interlayer Blade 3, the outside of the cylinder 1 have roller-way 4, the rib of the inwall surrounding weld horizontal of cylinder 1 placement at the rear portion of inner bag 2 5, it is uniformly distributed by certain spacing, this spacing is determined according to casting size, and the inwall surrounding of cylinder 1 behind rib 5 is broken Four short four-head pitch guiding ribs 6 of continuous welding, exit cone is extended to along the hand of spiral in certain level inclination Section 7, the level inclination in figure is octave.The effect of rib 5 is that casting rolling is driven when cylinder 1 rotates, and is taken off in casting die cavity The core in portion.Four-head pitch guiding rib 6 plays a part of shunting, accelerates the gait of march of molding sand and casting, avoids inside cylinder 1 Molding sand and casting accumulation, casting rolling time in cylinder 1 is reduced, and casting is arranged in an orderly manner, the conveyor screw piece 3 in front end Propulsion under slowly skid off cylinder 1, so as to reduce mutually collide between casting caused by cast(ing) surface damage.

Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real The content being not limited to new technical scope on specification, it is necessary to which its technology is determined according to right Property scope.
