Description
Technical field
The invention belongs to casting technology field, and in particular to for sandbox clamp device and its application method.
Background technology
Sand casting is current the most widely used casting technique, main reason is that：Than other casting methods, sand
Mold casting cost is low, simple production process, single-piece production with short production cycle, to casting, produces by batch and largely produces equal energy
Adapt to.In the world, in whole castings productions, 60~70% casting is produced with sand casting.
In actual production, the sandbox fastening means of sand casting is varied, and plurality enterprise uses square iron frame set
To be hung above and below sandbox upper, timber wedge is knocked between iron frame and is fastened, this method can not only produce vibration in fastener cycle,
So that residual sand increases inside cavity, the possibility that burning into sand defect occurs in casting is added, and operation is also very cumbersome, and fastening is not
Enough safety, easily occurs badly bleeding accident.
It can be seen from the above that existing sandbox clamp device and method there are it is larger the defects of, be easy to cause the missing of casting quality,
Make useless part occurrence rate higher, meanwhile, complicated, there are larger security risk.The present invention provides a kind of sandbox clamp device
And its application method can solve above-mentioned technical problem.
The content of the invention
In view of above-mentioned technical problem exists in the prior art, the present invention provides a kind of easy to use, safe laborsaving and can be with
The dual-purpose sandbox clamp device adjusted freely according to the distance between upper drag box, and a kind of easy to operate, safety labor-saving is provided
Dual-purpose sandbox clamp device application method.
The concrete technical scheme of dual-purpose sandbox clamp device of the present invention is：The dual-purpose sandbox clamp device, bag
Include lower draw-bar, upper and lower fastening face, torsion circle, thread cap, threaded rod, guide rod, fastening iron, the lower fastening of lower draw-bar connection
Face, lower fastening face are fixed on guide rod.The epimere of the guide rod is threaded rod.The upper fastening face of upper hook connection, threaded rod can be from
Upper fastening face center passes freely through.Torsion circle is integral with thread cap, is connected through a screw thread between thread cap and threaded rod.It is described
Fastening iron may be inserted into torsion circle.
Packing ring is equipped between the thread cap and lower fastening face.
In the present invention, the epimere of the guide rod is threaded rod, both are integral, it is ensured that the entirety of device is strong
Degree.
The upper hook is symmetrically placed with lower draw-bar, and there is barb disconnecting prevention structure in end, can prevent sandbox from hanging tight
Come off during Gu.
The upper fastening face is parallel with lower fastening face, and flat shape is consistent, and is bonded when being fastened to sandbox U-type groove
It is even closer, firm.
The threaded rod can be freely up and down movable among upper fastening face, so as to adjust upper fastening face and lower fastening freely
The distance between face, suitable for being fastened between the sandbox of various sizes specification.
The fastening iron, which may be inserted into torsion circle, to be rotated, and is driven thread cap to be connected with threaded rod, is rotated through
Journey make use of lever principle, so fastener cycle is very laborsaving.
It can be seen from the above that dual-purpose sandbox clamp device of the present invention has easy to operate, safety labor-saving simultaneously can basis
The distance between sandbox regulatory function freely.
Based on sandbox clamp device of the present invention, present invention also offers the application method of the clamp device, it has
Body technique scheme is：A kind of application method of dual-purpose sandbox clamp device, comprises the following steps：
The first step, four sets of sandbox clamp devices has been respectively combined spare；
Second step, selects sandbox to hang handle or the upper and lower U-type groove alternative one of sandbox up and down as sandbox fastening structure；
3rd step, two people station is in sandbox both sides diagonal position, each using a set of sandbox clamp device, if on selection sandbox
Under hang being used as sandbox fastening structure, the upper sandbox that hangs over is hung oneself a upside, lower draw-bar is hung over a downside is hung under sandbox,
Lower draw-bar hangs a center on a vertical curve up and down with sandbox in holding；If selecting sandbox, U-type groove is fastened as sandbox up and down
Structure, by threaded rod through U-type groove on sandbox, makes fastening face with being close on the upside of U-type groove on sandbox, while guide rod is passed through sand
U-type groove under case, makes lower fastening face with being close on the downside of U-type groove under sandbox；
4th step, manual rotation torsion circle, makes thread cap gradually be screwed with screw rod, is tentatively fastened；
5th step, by fastening iron insertion torsion circle, using lever principle, two people while rotational fastener iron, drive torsion circle
Rotate, be finally completed fastener cycle；
6th step, repeats above-mentioned 3rd step to the 5th step, complete another it is diagonal on two sets of clamp devices use.
After the application method of invention, since the mating connection between thread cap and threaded rod is driven by fastening iron
Torsion circle rotation is promoted, therefore fastener cycle is very laborsaving；Whole fastener cycle need not beat, and will not cause vibrations, reduce
To bringing the possibility of residual sand in cavity in sandbox fastener cycle, so as to reduce the generation of casting defect；It is equal to link up with end
There is barb disconnecting prevention structure, can prevent sandbox from hanging handle and coming off in fastener cycle；Fastener cycle diagonally while is completed by two people, is subtracted
The risk of sandbox mould shift is lacked, four sets of clamp devices use at the same time, and sandbox fastening is safer, avoids the hair of badly bleeding accident
It is raw.
The present invention has the advantages that：1st, the dual-purpose sandbox clamp device is simple in structure, easy to operate, can be quick
Effectively tighten sandbox；2nd, when using the sandbox clamp device, without beaing, vibrations will not be caused, reduce casting hair
The probability of raw defect；3rd, the clamp device, which can use, hangs using or uses fastening structure of the U-type groove as sandbox, its
Hook end is equipped with barb disconnecting prevention structure；4th, when using the clamp device, the risk of sandbox mould shift, four sets of fastenings are reduced
Device uses at the same time, and sandbox fastening is safer, avoids the generation of badly bleeding accident.
