Description
Technical field
The invention belongs to casting technology field, be particularly used for sandbox clamp device and using method thereof.
Background technology
Sand casting is currently used most commonly used casting technique, main reason is that: than other casting method, sand casting cost is low, production technology is simple, with short production cycle, to the single-piece production of foundry goods, produce by batch and produce in a large number and all adapt to. In the world, in whole castings production, the foundry goods of 60～70% sand casting produces.
In actual production, the sandbox fastening means of sand casting is varied, the plurality enterprise square chase of employing is enclosed within sandbox and hangs upper up and down, knocking in timber wedge between chase to fasten, this method not only can produce vibration in fastener cycle so that the internal residual sand of die cavity increases, add foundry goods and the probability of burning into sand defect occurs, and operate also very loaded down with trivial details, fasten safe not, badly bleeding accident easily occurs.
As can be seen here, there is bigger defect in existing sandbox clamp device and method, it is easy to causes the disappearance of casting quality, makes useless part occurrence rate higher, meanwhile, complicated operation, there is bigger potential safety hazard. The invention provides a kind of sandbox clamp device and using method can solve the problem that above-mentioned technical problem.
Summary of the invention
In view of prior art exists above-mentioned technical problem, the present invention provides dual-purpose sandbox clamp device that is a kind of easy to use, safe laborsaving and that freely can regulate according to the distance between upper drag box, and provides the dual-purpose sandbox clamp device using method of a kind of simple to operate, safety labor-saving.
The concrete technical scheme of dual-purpose sandbox clamp device of the present invention is: described dual-purpose sandbox clamp device, including upper lower draw-bar, fasten face, torsion circle, thread cap, threaded rod, guide rod, fastening iron up and down, described lower draw-bar fastens face under connecting, and lower fastening face is fixed on guide rod. The epimere of described guide rod is threaded rod. Upper hook connecting connects fastening face, and threaded rod can pass freely through from center, upper fastening face. Torsion circle and thread cap are an entirety, are threaded connection between thread cap and threaded rod. Described fastening iron may be inserted in torsion circle.
It is provided with packing ring between described thread cap and lower fastening face.
In the present invention, the epimere of described guide rod is threaded rod, and both are an entirety, it is ensured that the bulk strength of device.
Described upper hook is symmetrically placed with lower draw-bar, and end all has barb disconnecting prevention structure, can prevent sandbox from hanging coming off in fastener cycle.
Described upper fastening face is parallel with lower fastening face, and flat shape keeps consistent, and when sandbox U-type groove is fastened, laminating is more closely, firmly.
Described threaded rod can be freely up and down movable in the middle of upper fastening face, thus freely regulating upper distance between fastening face and lower fastening face, it is adaptable to fasten between the sandbox of various sizes specification.
Described fastening iron may be inserted in torsion circle and rotates, and drives thread cap and threaded rod to be connected, and rotary course make use of lever principle, so fastener cycle is very laborsaving.
As can be seen here, dual-purpose sandbox clamp device of the present invention has simple to operate, safety labor-saving can according to the regulatory function freely of the distance between sandbox.
Based on sandbox clamp device of the present invention, present invention also offers the using method of this clamp device, its concrete technical scheme is: the using method of a kind of dual-purpose sandbox clamp device, comprises the following steps:
The first step, overlaps sandbox clamp device by four and has been respectively combined standby;
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 stand in sandbox both sides diagonal position, each use a set of sandbox clamp device, if selecting sandbox to hang as sandbox fastening structure up and down, upper hook hangs over sandbox hang oneself a upside, being hung over by lower draw-bar and hang a downside under sandbox, in maintenance, lower draw-bar and the upper and lower Diao Ba center of sandbox are on a vertical curve; If selecting the upper and lower U-type groove of sandbox as sandbox fastening structure, by threaded rod through U-type groove on sandbox, making to be close on the upside of fastening face and U-type groove on sandbox, simultaneously by guide rod through U-type groove under sandbox, making to be close on the downside of lower fastening face and U-type groove under sandbox;
4th step, manual rotation torsion circle, make thread cap and screw rod screw gradually, tentatively fasten;
5th step, inserts torsion circle by fastening iron, utilizes lever principle, and two people are rotational fastener iron simultaneously, drives torsion circle to rotate, is finally completed fastener cycle;
6th step, repeats above-mentioned 3rd step to the 5th step, completes two on another one diagonal angle and overlap the use of clamp devices.
After adopting the using method of invention, being promoted owing to being connected between thread cap and threaded rod is driven torsion circle to rotate by fastening iron, therefore fastener cycle is very laborsaving; Whole fastener cycle, without beaing, will not cause vibrations, reduces to the probability bringing residual sand in die cavity in sandbox fastener cycle, thus decreasing the generation of casting defect; Hook end all has barb disconnecting prevention structure, can prevent sandbox from hanging coming off in fastener cycle; Fastener cycle is to be simultaneously completed by two people diagonal angles, decrease the risk of sandbox mould shift, and four set clamp devices use simultaneously, and sandbox fastening is safer, it is to avoid the generation of badly bleeding accident.
There is advantages that 1, described dual-purpose sandbox clamp device simple in construction, easy to operate, can fast and effeciently fasten sandbox; 2, when using described sandbox clamp device, it is not necessary to beat, vibrations will not be caused, decrease the probability of foundry goods generation defect; 3, described clamp device both can use and hang using using the U-type groove fastening structure as sandbox, and its hook end is provided with barb disconnecting prevention structure;4, when using described clamp device, decreasing the risk of sandbox mould shift, four set clamp devices use simultaneously, and sandbox fastening is safer, it is to avoid the generation of badly bleeding accident.
