The detachable box belt consists of a short box belt and box belt edges arranged at two ends of the short box belt, and the two box belt edges are respectively provided with bolt holes; the detachable box belts are respectively distributed and supported between every two long box belts, a plurality of bolt holes are arranged on the long box belts at intervals, and the bolt holes of the detachable box belts are in butt joint with the bolt holes of the long box belts and penetrate through the connecting bolts for fixing. The invention can effectively avoid the accessory interference position of the water-cooling iron casting, does not need to cut the box belt, does not need to weld the box belt again, can reserve the extending positions of the cooling pipe and the dead head, improves the production efficiency and prolongs the service life of the sand box, and has simple and flexible operation.
Description
Technical Field
The invention relates to metallurgical casting, in particular to a manufacturing method of a detachable box belt type sand box.
Background
There are many large water-cooled iron castings in the metallurgical industry, and the casting of such water-cooled castings requires the use of large rectangular steel-structured sand boxes of 2.5 × 1.5m, 3.0 × 2.0m and above, which are composed of box frames and box bands, and are generally welded by steel structures. 2-8 cooling pipes are cast in the large water-cooling iron castings, and the pipe orifices of the cooling pipes extend out of the castings and extend out of the sand box; in addition, fittings such as risers can touch the strap, which requires cutting the strap. The extending positions of water pipes and risers of different castings are different, and the cutting positions of the box belt are also different, so that the box belt of the sand box is always in the cycle process of cutting, welding and repairing and cutting, and a large amount of labor cost and material cost are consumed; meanwhile, the cutting of the box belt is more, the strength and the rigidity of the sand box can be influenced, the sand box is easy to deform, and the service life is reduced; smoke dust is generated in the cutting and welding process, so that the cutting and welding operations of the box belt are reduced, and the method is of great significance to casting enterprises.
Conventional fixed box-belt sand box casting enterprises cannot meet the requirements of large-scale water-cooling iron castings and the requirements of cost reduction, environmental protection and the like which are continuously improved by the enterprises, so that a steel structure sand box which can reduce or avoid cutting and welding of a box belt is designed, so that the extending positions of a cooling pipe and a riser can be reserved, the production efficiency can be improved, the service life of the sand box can be prolonged, and the aim of pursuing by technicians in the field is fulfilled.
Disclosure of Invention
The invention aims to provide a manufacturing method of a detachable box belt type sand box, which can effectively avoid the accessory interference position of a water-cooling iron casting, does not need to cut a box belt and weld the box belt again, meets the requirement of a casting enterprise for producing large-scale water-cooling iron castings, and solves the problems that the casting is loosened due to insufficient rigidity of the casting sand box used by the prior casting manufacturer during sand casting, and the casting is scrapped seriously.
The technical solution of the invention is as follows:
a manufacturing method of a detachable box belt type sand box is characterized in that a plurality of long box belts are arranged in the length X direction of a steel structure sand box and are arranged on a general casting side by side for fixing, and a plurality of short box belts are arranged in the Y direction of the steel structure sand box and are detachable box belts;
the detachable box belt consists of a short box belt and box belt edges arranged at two ends of the short box belt, and the two box belt edges are respectively provided with a bolt hole; the detachable box belts are respectively distributed and supported between every two long box belts, a plurality of bolt holes are arranged on the long box belts at intervals, and the bolt holes of the detachable box belts are in butt joint with the bolt holes of the long box belts and penetrate through the connecting bolts for fixing.
The hole diameter of the bolt hole of the long box belt is 20 mm.
The bolt hole aperture of the detachable box belt is 20 mm.
According to the manufacturing method of the detachable box belt type sand box, the position of interference of accessories of the water-cooling iron casting can be effectively avoided, the box belt does not need to be cut, the box belt does not need to be welded again, and the requirement of a casting enterprise for producing large-scale water-cooling iron castings is met.
By adopting the manufacturing method of the detachable box belt type sand box, the steel structure sand box with the box belt cut and welded can be reduced or avoided, so that the extending positions of the cooling pipe and the riser can be reserved, the production efficiency and the service life of the sand box are improved, the operation is simple and flexible, the smoke dust caused by cutting and welding is reduced, and the on-site environmental protection requirements of casting enterprises are met.
