Description

Technical Field

[0001] This utility model belongs to the field of casting technology, and in particular relates to a casting tooling for the bottom of cast steel wheels for railway freight cars. Background Technology

[0002] During the casting process of cast steel wheels, the bottom ladle is prone to shaking due to the pressure of the bottom ladle during casting. When casting is carried out in this state, the molten steel flowing out of the bottom ladle also shakes, resulting in extremely unstable filling of the mold with molten steel. This not only wastes time and effort but also affects product quality and production efficiency.

[0003] Therefore, given that the bottom injection ladle is prone to shaking, which seriously affects product quality and production efficiency, there is a need to provide a tooling for casting bottom injection ladles for railway freight car cast steel wheels to solve the above technical problems. Utility Model Content

[0004] To address some or all of the technical problems existing in the prior art, this utility model provides a casting tooling for the bottom injection ladle of a railway freight car cast steel wheel, comprising a hand-held component, a bottom injection ladle fixing buckle, and a connecting component, wherein: the bottom injection ladle fixing buckle is disposed on the top of the hand-held component for fixing the bottom injection ladle, and the connecting component is disposed between the hand-held component and the bottom injection ladle fixing buckle for non-destructive assembly and disassembly of the hand-held component and the bottom injection ladle fixing buckle.

[0005] Furthermore, in the aforementioned casting tooling for the bottom injection ladle of cast steel railway freight car wheels, the bottom injection ladle fixing buckle is arranged in an arc shape.

[0006] Furthermore, in the aforementioned casting tooling for the bottom injection ladle of cast steel railway freight car wheels, the bottom injection ladle fixing buckle is made of heat-resistant steel bars with a diameter of 30mm-45mm bent.

[0007] Furthermore, in the above-mentioned casting tooling for the bottom injection ladle of cast steel railway freight car wheels, the connecting assembly includes a connecting body and a limiting platform. The connecting body is welded to the middle of the bottom injection ladle fixing buckle, and the limiting platform is fixedly connected to the handheld assembly. A limiting groove is provided on the connecting body, and the limiting groove matches the limiting platform. The connecting body and the limiting platform are connected through the limiting groove.

[0008] Furthermore, in the aforementioned casting tooling for the bottom of cast steel wheels of railway freight cars, the limiting platform is equipped with a press-type spring locking tongue structure.

[0009] The casting tooling for the bottom slurry of the cast steel railway freight car wheel of this utility model has the following advantages and beneficial effects:

[0010] This utility model has a simple overall structure and can effectively fix various types of bottom injection ladles by replacing the bottom injection ladle fixing buckle, thereby effectively stabilizing the molten steel flow and effectively improving the quality and production efficiency of wheel products. Attached Figure Description

[0011] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only for further understanding of the embodiments of the present invention and constitute a part of the present invention.

[0015] 3: Connecting component, 31: Connecting body, 311: Limiting groove, 32: Limiting platform. Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] like Figure 1 As shown, the casting tooling for the bottom injection pot of the cast steel wheel of the railway freight car of this utility model includes a hand-held component 1, a bottom injection pot fixing buckle 2, and a connecting component 3. The bottom injection pot fixing buckle 2 is set on the top of the hand-held component 1 for fixing the bottom injection pot. The connecting component 3 is set between the hand-held component 1 and the bottom injection pot fixing buckle 2 for non-destructive assembly and disassembly of the hand-held component 1 and the bottom injection pot fixing buckle 2.

[0018] Preferably, the handheld part of the handheld component 1 is covered with rubber, which effectively improves the friction.

[0019] Furthermore, in the casting tooling for the bottom injection pot of the cast steel wheel of the railway freight car of this utility model, the bottom injection pot fixing buckle 2 is set in an arc shape, so that it can fit tightly with the bottom injection pot and effectively ensure the bottom injection pot is fixed.

[0020] Furthermore, in the casting tooling for the bottom injection ladle of the cast steel wheel of the railway freight car of this utility model, the bottom injection ladle fixing buckle 2 is made of heat-resistant steel bar with a diameter of 30mm-45mm bent, thereby effectively preventing the bottom injection ladle from overheating and causing the bottom injection ladle fixing buckle 2 to soften.

[0021] Furthermore, in the casting tooling for the bottom injection jar of the cast steel wheel of the railway freight car of this utility model, the connecting component 3 includes a connecting body 31 and a limiting platform 32. The connecting body 31 is welded to the middle of the bottom injection jar fixing buckle 2, and the limiting platform 32 is fixedly connected to the hand-held component 1. A limiting groove 311 is provided on the connecting body 31, and the limiting groove 311 matches the limiting platform 32. The connecting body 31 and the limiting platform 32 are connected through the limiting groove 311, which facilitates the replacement of the bottom injection jar fixing buckle 2 so as to be applicable to the fixing of various models of bottom injection jars.

[0022] Furthermore, in the casting tooling for the bottom of the cast steel wheel of the railway freight car of this utility model, the limiting platform 32 adopts a pressing spring locking tongue structure to achieve quick disassembly.

[0023] Specifically, during the pouring process, a bottom pouring pot fixing clip 2 with a curvature close to that of the bottom pouring pot is first selected. At this time, the top of the handheld component 1 is inserted into the connecting body 31, and the limiting platform 32 is aligned with the limiting groove 311. Since the limiting platform 32 adopts a press-type spring locking tongue structure, it will not interfere with the connecting body 31 when inserting or removing it, thus facilitating the installation and removal of the bottom pouring pot fixing clip 2. At this time, pressing the limiting platform 32 limits the limiting platform 32 and the limiting groove 311, which not only effectively improves the installation efficiency but also effectively avoids the danger of the bottom pouring pot fixing clip 2 coming off during use. At this time, the handheld component 1 drives the bottom pouring pot fixing clip 2 to fit the bottom pouring pot, thus effectively preventing the bottom pouring pot from shaking during the pouring process.

[0024] In summary, compared with the prior art, the casting ladle tooling for the bottom of the cast steel railway freight car wheel of this utility model has the following advantages and beneficial effects:

[0025] This utility model has a simple overall structure and can effectively fix various types of bottom injection ladles by replacing the bottom injection ladle fixing buckle, thereby effectively stabilizing the molten steel flow and effectively improving the quality and production efficiency of wheel products.
