Problems solved by technology

[0007] Although the above-mentioned structure is simple, it also has defects. For example, molten iron flows directly from the molten iron insulation tank into the molten iron drainage tank 21, then quickly flows into the front end 24 of the drainage tank, and flows out of the casting through the opening 23 at the bottom of the tank. It is always in a flowing state, so the molten iron is measured more difficult
The molten iron enters the back end 22 of the drainage tank from the incubator and then enters the front end 24 of the drainage tank. Manual inspection cannot be realized, and the oxidation slag in the molten iron cannot be removed, which affects the casting quality

Embodiment 1

[0025] The structure of this embodiment is suitable for casting the gray cast iron friction layer on the inner wall of the rotating brake drum shell during centrifugal casting of the bimetallic brake drum.

[0026] Such as figure 1 As shown, the basic structure of this embodiment is to set a horizontal sliding device on a suspension rail, the sliding device is provided with a linear reciprocating movement mechanism, a rotary reciprocating swing mechanism is arranged on the linear reciprocating movement mechanism, and an overturning device is arranged on the rotary reciprocating swing mechanism. Set the molten iron ladle on the turning device. Therefore, the molten iron ladle can be overturned, rotated and reciprocated, and can also be reciprocated in a straight line to realize the multi-dimensional movement of the molten iron ladle. At the same time, a metering device is also installed on the above-mentioned device to measure the weight of molten iron to realize positioning,...

Embodiment 2

[0040] Such as Figure 4 As shown, this embodiment is basically the same as Embodiment 1, and the different parts of the structure no longer use the suspension rail structure, but the ground rail structure. That is, the ground rail is set on the ground or the platform, the sliding track 1 is arranged on the ground rail, the sliding drive motor 4 and the sliding deceleration device 3 are arranged on the sliding chassis 2, the metering box 7 is arranged on the sliding chassis 2, and the tension pressure sensor is arranged in the metering box 7 8. The upper end of metering 7 is provided with turning over cabinet 14 again. That is to say, the present embodiment removes the rotary reciprocating swing mechanism of the first embodiment, and other structures and positions are just opposite to those of the first embodiment, and the turning case 14 is arranged at the top of the device. The upper side of the molten iron ladle 15 can be directly docked with the molten iron heat preserva...

Embodiment 3

[0043] This embodiment is also a structural change on the basis of Embodiment 1. This embodiment also adopts the suspension rail structure, removes the rotary reciprocating swing mechanism, and directly connects to the flipping cabinet 14 through the metering box 7 at the lower end of the sliding cabinet 2 . Setting the overturning shaft 16 to a sufficient axial length can avoid the space position conflict between the suspension rail and the molten iron insulation bag, but due to the extension of the overturning shaft 16, a corresponding counterweight body needs to be equipped at the same time.

Description

technical field [0001] The invention relates to a feeding device for centrifugal casting, in particular to a feeding device for molten iron suitable for centrifugal casting of bimetallic brake drums. Background technique [0002] During centrifugal casting, the molten iron needs to be transported to the casting area of ​​the centrifuge for casting. Since the casting area of ​​the centrifuge is located in a high-speed rotating annular space, the molten iron conveying device needs to have a moving function. For example, during centrifugal casting of bimetallic brake drums, the steel brake drum shell needs to be locked on the centrifuge, and the molten iron is centrifugally cast in a horizontal state. The centrifugal force of the rotation distributes the molten iron evenly. Therefore, the molten iron ladle used for centrifugal casting should extend into the inside of the bimetallic brake drum shell before casting. [0003] In order to transport molten iron into the horizontal...
