Abstract
The utility model relates to a large-size sand box turning over device, which comprises a sand box, wherein ear shafts are respectively arranged at both sides of the sand box, and the ear shafts arranged at both sides are respectively arranged in U-shaped openings of U-shaped support seats. During the turning over of the large-size sand box, the requirement on the capability of a crane is greatly reduced, in addition, the sand box is prevented from any impact in the turning over process, the large-size sand box turning over device is favorable for safety production and sand mold quality protection, the operation is very stable in the turning over process, and the sand mold is effectively protected.
Description
Technical field
The utility model belongs to casting technology field, and relating to a kind ofly provides stable support and help the large-scale sandbox mould rollover unit of its steady turning operation for large-scale sandbox.
Background technology
The sandbox turning operation is very crucial, must protect sand mold, has direct impact can cause the sand mold cracking, be out of shape even cave in as switching process to sandbox.
When adopting hand moulding to carry out Foundry Production, sandbox will will carry out once inside out through upset for several times after the under casing molding, will carry out twice upset when the face case is minimum.When hand moulding is produced, general aerial upset or the place mat upset dual mode of adopting of the upset of sandbox, though can slow down the impact that sandbox is subjected to a certain extent, but be that aerial upset or place mat upset all have higher requirements to the bearing capacity of workshop crane, because when sandbox climbs over 90 °, can under the gravity effect, quicken rotation, suspender is caused very big impulsive force, the bearing capacity of crane must be greater than the summation of sandbox (containing sand mold) net weight with the upset impulsive force, and whole switching process is very big threat to trouble free service.
Foundry Works often will constantly break through the single products weight limit according to the variation in market, and it is more and more heavier that product is done by institute.For large-scale sandbox, itself be very heavy, the bearing capacity that improve the workshop crane is not easy again, spend substantial contribution to buy more large-scale crane, even the workshop that also needs reinforcement.
Adopt the traditional approach large-scale sandbox that overturns seriously restricted by two aspects: the one, the weight capacity in crane and workshop will have the safe enough coefficient, the 2nd, traditional upset mode can only be slowed down impact, can not avoid impacting, large-scale sand mold is easy more to cause damage in switching process.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art; the utility model provides a kind of and stable support is provided and helps its steady turning operation for large-scale sandbox; the impact of having avoided traditional-handwork moulding mould turnover to be produced; significantly reduced workshop and crane demands for bearing capacity, can protect the large-scale sandbox mould rollover unit of sand-mould quality simultaneously again.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of large-scale sandbox mould rollover unit, comprise sandbox, and be respectively equipped with gudgeon in the both sides of sandbox, the gudgeon of both sides places respectively in the U-shaped mouth of U-shaped supporting seat.
Described U-shaped supporting seat is provided with base or the support platform that is used.
The gudgeon of described sandbox both sides is arranged near the center line of sandbox.
The shape of described gudgeon matches with the U-shaped mouth of U-shaped supporting seat.
The beneficial effects of the utility model are: when large-scale sandbox overturns; reduce requirement greatly to hoisting power; and can avoid the suffered any impact of sandbox in switching process; help keeping the safety in production and the protection of sand-mould quality; in switching process; move very steadily, sand mold is effectively protected.
Description of drawings
Fig. 1 is the structural representation of the utility model when using on ground.
Fig. 2 is the structural representation of U-shaped supporting seat described in the utility model when melt pit uses.
Among the figure: 1-U shape supporting seat, 2-U shape mouth, 3-sandbox, 4-gudgeon, 5-base, 6-support platform.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1, a kind of large-scale sandbox mould rollover unit, comprise sandbox 3, be respectively equipped with gudgeon 4 in the both sides of sandbox 3, the gudgeon 4 of sandbox 3 both sides places respectively in the U-shaped mouth 2 of U-shaped supporting seat 1, when using on ground, the a pair of gudgeon 4 of sandbox 3 is arranged on sandbox 3 center lines or omits disalignment, the shape of gudgeon 4 matches with the U-shaped mouth of U-shaped supporting seat, the base 5 of as shown in Figure 1 U-shaped supporting seat 1 is placed on the ground, make U-shaped supporting seat 1 segment distance above ground level, and make the sandbox 3 can be unsettled fully.As shown in Figure 2, when the utility model uses in melt pit,, make U-shaped supporting seat 1 exceed melt pit ground one segment distance, and make the sandbox 3 can be unsettled fully placing on the support platform 6 of U-shaped supporting seat 1.
Operation of the present utility model is very convenient, and its operating procedure is as follows: after the moulding molding, earlier that sandbox 3 handlings are on the throne to repaking mechanism institute; Then sandbox 3 a pair of gudgeons 4 are aimed at the U-shaped mouth 2 of U-shaped supporting seat 1, slowly descended and be inserted in, put steady; Adopt crane slowly to spur sandbox 1 one sides again, sandbox 1 is slowly rotated; After at last sandbox 3 being turn to horizontal level, sandbox 3 is steadily left under order.
In experimentation, the applicant has made a covering device, is installed in the medium casting workshop.This workshop weight capacity and the specified bearing capacity of crane all are 30 tons; adopt the utility model successfully to carry out the upset of the large-scale sandbox of 6300mm * 3300mm, sandbox adds the sand mold gross weight near 30 tons, in switching process; move very steadily, sand mold is effectively protected.
