Description
Technical field
The utility model relates to casting technology field, and in particular to a kind of clamping device of massive casting sandbox.
Background technique
Casting is will to be poured into casting mold by the metal liquid of melting, shape and performance needed for obtaining through cooled and solidified
The manufacturing process of part.
Before casting of molten metal, the good corresponding type chamber of moulding is first wanted, it is often necessary to which the casting for manufacturing sand mold is set
It is standby, it will be in loose molding sand filling sandbox；Consolidation molding sand, by ram-jolt, compacting, jolt-squeeze, penetrate pressure etc. distinct methods make in sandbox
Loose molding sand consolidation has necessary strength sand mold during carrying and casting etc.；Using different institutions by apperance from
It is taken out in sand mold after consolidation, to complete moulding.
Heavy castings weight is big, and in molten steel pouring course, due to pouring head height, dynamic pressure and static pressure are big, huge
The fastening means (conventional to make to tense upper box and lower box to install bolt in sandbox side) of expansive force routine is not able to satisfy and wants
It asks, such as occurs sandbox expansion, the problems such as casting generates outer dimension, shape and weight, inside solid degree and fire check, when serious
The excessive scrap of the product of molten iron, there is also security risks.
Summary of the invention
The purpose of the utility model is to provide a kind of clamping devices of massive casting sandbox by spreading that avoids sandbox.
Realize that the technical solution of above-mentioned purpose is as follows:
The clamping device of massive casting sandbox, comprising: sandbox ontology；
Multiple crossbeams along sandbox ontology lateral arrangement, the both ends of crossbeam are equipped with first through hole, the distribution of these crossbeams
In the top and bottom of sandbox ontology；
It is multiple along the longitudinally arranged stringer of sandbox ontology, one end of stringer is placed through the of sandbox bodies top crossbeam
One through-hole, the other end of stringer are placed through the first through hole of sandbox body bottom portion crossbeam, these crossbeams form multiple with stringer
Frame, sandbox ontology are clamped by these frames.
Further, the stringer includes:
Stringer ontology has been longitudinally arranged multiple second through-holes along sandbox ontology on stringer ontology；
Gag lever post, after the end of the stringer ontology passes through the first through hole on crossbeam, it is logical that the gag lever post passes through second
Hole forms crossbeam and limits.
It further, further include several cushion blocks, these cushion blocks are clamped between crossbeam and sandbox ontology, or are clamped
Between stringer and sandbox ontology.
Further, the both ends of the crossbeam are equipped with the opening being connected to first through hole.
The utility model by the combination of crossbeam and stringer, formed the mode of firm " well " glyph framework to sandbox ontology into
Row is fastened up and down, guarantees that sandbox ontology is indeformable.The utility model solves the problems, such as that heavy castings are poured the case that rises,
Guarantee that product outline size precision weight tolerance reaches CT10 grades, dense internal organization zero defect.
Detailed description of the invention
Fig. 1 is the installation diagram of the utility model；
Fig. 2 is the structural schematic diagram of the crossbeam in the utility model；
Fig. 3 is the structural schematic diagram of the stringer in the utility model.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.
As shown in Figure 1 to Figure 3, the clamping device of massive casting sandbox, it is sandbox ontology 1, multiple lateral along sandbox ontology
It is the crossbeam 2 of arrangement, multiple along the longitudinally arranged stringer 3 of sandbox ontology, several cushion block (not shown)s, separately below to each
Part and the relationship between them are described in detail:
The both ends of crossbeam 2 are equipped with first through hole 20, these crossbeams 2 are distributed in the top and bottom of sandbox ontology 1, and first
The shape of through-hole 20 can be circle, be also possible to polygon.The both ends of the crossbeam 2, which are equipped with, to be connected to first through hole 20
Opening 21.As shown in Fig. 2, crossbeam 2 is made of cross-beam body 22 and head 23, the outside of head 23 to cross-beam body 22 is convex
Out, the cross section of cross-beam body 22 is caused to be less than the longitudinal section on head 23, the first through hole 20 and the first opening 21 are respectively positioned on
Head 23, setting first are open after 21, when the sectional area of stringer 3 is slightly larger than the area of first through hole 20, are conducive to make stringer 3
It passes through.
One end of stringer 3 is placed through the first through hole 20 of 1 top cross-bar 2 of sandbox ontology, and the other end of stringer 3 passes through position
In the first through hole of sandbox body bottom portion crossbeam, the section of stringer 3 is formed preferentially to be selected to match with the shape of first through hole 20, example
Such as, when first through hole 20 is round, the cross sectional shape of stringer 3 is also circle, when first through hole 20 is polygon, stringer 3
Cross sectional shape is also polygon, naturally it is also possible to be mismatched, as long as stringer can pass through first through hole 20.These crossbeams 2
Multiple frames are formed with stringer 3, sandbox ontology 1 is clamped by these frames.
The stringer includes: stringer ontology 30 and gag lever post (not shown), along sandbox sheet on stringer ontology 30
Body has been longitudinally arranged multiple second through-holes 31；After the end of the stringer ontology 30 passes through the first through hole 20 on crossbeam 2, institute
It states gag lever post and limit is formed to crossbeam 2 across the second through-hole 31.1 position of crossbeam be limited in sandbox ontology 1 and gag lever post it
Between, so that crossbeam 1 can not move.
For several cushion blocks, these cushion blocks are clamped between crossbeam 2 and sandbox ontology 1, or are clamped at
Between stringer 3 and sandbox ontology 1, by the effect of cushion block, avoid on sandbox ontology it is certain loosening is locally present, therefore, into
Limitation is formd to one step to the position of sandbox ontology.Cushion block is tapered wedges, and tapered wedges facilitate insertion into crossbeam 2 and sandbox ontology
Between 1, and facilitate insertion between stringer 2 and sandbox ontology 1.
