Embodiment Construction

[0030] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] Such as Figure 4 As shown, the device in this embodiment includes an upper sand box 14, a sand core 5, a base and a loosening mechanism. The base includes a base frame 9 and a cold mold 12. The base frame 9 forms an annular groove 9-1, which is loaded into the cold mold. Type 12, the inner side of the cold type 12 forms an unclosed annular water flow channel 12-1 towards the inside, and the inner side of the water flow channel is sealed by the outer wall of the inner cylinder 9-2 of the base frame 9, between the cold type 12 and the base frame 9 Fixedly connected by several bolts 2, the bolts 2 extend upwards from the bottom of the base frame 9 to the bottom edge of the cold type 12. The contact portion between the cold type 12 and the base frame 9 is packed into the sealing ring 3, and the sealing ring 3 can be adorned with two,...

Abstract

The invention discloses a rapid progressive solidification technique device for a high manganese steel rolling mortal wall casting. The rapid progressive solidification technique device comprises a cope box, a core and a base. The core is arranged in the cope box. The bottom of the cope box is fixedly connected with the base. The base comprises a base frame and a cooling device. An annular groove is formed in the base frame. The annular groove is arranged in the cooling device and forms an annular water flow channel. The water flow channel is communicated with a water inlet pipe and a water outlet pipe. In work, the cooling face of the cooling device is tightly attached to the work face of an inner cavity of the casting. By the adoption of the rapid progressive solidification technique device, it is guaranteed that the cast structure of a rolling mortal wall, especially the important work portion of the rolling mortal wall is small in crystal particle size and free of a shrinkage cavity, shrinkage porosity and a slag inclusion defect in the casting process.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment manufacturing, and in particular relates to a technical device for rapid sequential solidification of high manganese steel rolling socket wall castings. [0002] technical background [0003] Cone crusher is a kind of mechanical equipment for metallurgy, chemical industry, building materials, hydropower, mining, transportation construction and other industrial departments to crush and finely crush various ores or rocks with different hardness. It has reliable structure, stable operation, high production efficiency, adjustment Convenience, uniform product size and so on. It works as figure 1 As shown, wherein, part 1' is the wall of the rolling socket, part 2' is the broken wall, part 3' is the bevel gear, and part 4' is the eccentric swinging mechanism. [0004] In the crusher, the rolling mortar wall and the crushing wall are two key components in the operation process of the equipm...
