Abstract
The utility model discloses a casting system of a C-class steel wheel center casting for a rail transit. The casting system comprises a feeding blind feeder (1), a chiller (2) and an edge pressing feeding head (3); the casting system is characterized in that the feeding blind feeder (1) is arranged at the position of a wheel center shaft hole, the edge pressing feeding head (3) is arranged at the position of a wheel center flange, and the chiller (2) is arranged at the positions of the wheel center shaft hole and the wheel center flange. The casting system solves the technical problems that a partial feeder head pad or a whole pad is arranged at the position of the shaft hole of the casting and is removed through machining turning.
Description
Technical field
The utility model relates to a kind of casting system, and more particularly, the utility model relates to a kind of casting system of track traffic C level steel wheel heart foundry goods.
Background technology
Very strict for the specification requirement of C level steel wheel heart foundry goods in railway/track traffic, do not allow product to have shrinkage cavity, loose and defects i.e.cracks, and product need be checked through ultrasonic examination.The weak point that traditional technique exists is because product is low-alloy steel (C level steel) material, and there is no chill, in foundry production than being easier to crack defect and qualification rate is low.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of casting system of track traffic C level steel wheel heart foundry goods is provided.
For realizing above object, the technical solution adopted in the utility model is: a kind of casting system of track traffic C level steel wheel heart foundry goods, it comprises feeding blind riser (1), chill (2), flanging feeding head (3), it is characterized in that, described feeding blind riser (1) is arranged on core wheel axis hole position; Described flanging feeding head (3) is arranged on core wheel wheel rim position; Described chill (2) is arranged in core wheel axis hole position and core wheel wheel rim position.
The beneficial effects of the utility model are simple in structure, easy operatings; Eliminated product and had shrinkage cavity, loose and defects i.e.cracks, product qualified rate is high.

The specific embodiment
In order to make those skilled in the art understand better the technical solution of the utility model; below in conjunction with accompanying drawing, the utility model is described in detail; the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
Referring to Fig. 1,2,3,4, a kind of casting system of track traffic C level steel wheel heart foundry goods, it comprises feeding blind riser 1, chill 2, flanging feeding head 3, it is characterized in that, described feeding blind riser 1 is arranged on core wheel axis hole position; Described flanging feeding head 3 is arranged on core wheel wheel rim position; Described chill 2 is arranged in core wheel axis hole part, core wheel wheel rim position.
Referring to Fig. 5,6,7, a kind of casting system of track traffic C level steel wheel heart foundry goods, it comprises feeding blind riser 1, chill 2, flanging feeding head 3, it is characterized in that, described feeding blind riser 1 is arranged on core wheel axis hole position; Described flanging feeding head 3 is arranged on core wheel wheel rim position; Described chill 2 is arranged in the whole position of core wheel axis hole, core wheel wheel rim position.
The operation principle of embodiment 1, embodiment 2: shrinkage porosite is easily caused at the core wheel axis hole position of foundry goods, because this position is final set position, when casting solidification, molten metal has been mended and had previously been solidified position and formed shrinkage porosite, add feeding blind riser so herein, be in order to ensure enough and to guarantee that the molten metal of its mobility carrys out feeding, thereby eliminate defect.
It should be noted that, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thereby which key element the process, method, article or the equipment that make to comprise a series of key elements not only comprise, but also comprise other key elements of clearly not listing, or be also included as the intrinsic key element of this process, method, article or equipment.The in the situation that of more restrictions not, the key element being limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment that comprises key element and also have other identical element.
Applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof.The above is only preferred embodiment of the present utility model, should be understood that, finiteness due to literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvement, retouching or variation, also above-mentioned technical characterictic can be combined by rights; These improve retouching, change or combination, or without improving, the design of utility model and technical scheme are directly applied to other occasion, all should be considered as protection domain of the present utility model.
