A batch type forming device for coke oven door bolt

Abstract

The invention relates to the field of metal casting processing, in particular to a coke oven door bolt batch forming device, comprising a base and a die table, a controller, an extrusion mechanism and three lower dies, wherein the extrusion mechanism is arranged on the bottom of the base. The top is used for die-casting the door bolt, and the extrusion mechanism includes a first pressing plate, a second pressing plate, a pressing component, two sliding components, two pulling components and three upper dies, and the three lower dies are arranged on the die at equal intervals. The inside of the table is used to hold the molten metal, and two baffles are fitted between each two lower molds, and the bottom of each baffle is fixedly connected with the inner bottom of the mold table. The components are electrically connected with the controller. The present invention relates to a batch molding device and method for coke oven door bolts, which has better extrusion effect, stronger sealing performance, easy molding of products, and less bubbles on the surface after molding. The material process is simple, and the material retrieval saves time and effort.

Description

technical field [0001] The invention relates to the field of metal casting processing, in particular to a batch type forming device for coke oven door bolts. Background technique [0002] The auxiliary equipment of the coke oven that opens and closes the two ends of the coke oven carbonization chamber. When the furnace door is closed, the carbonization chamber is isolated from the atmosphere; when it is opened, the coke pusher rod can push out the coke. The coke oven door is divided into organic side door and coke side door. The upper end of the furnace door on the side of the machine is provided with a small furnace door for the flat coal rod to extend into the carbonization chamber for flat coal. The furnace door is composed of shell, lining brick, knife edge, horizontal iron and other parts. Modern coke ovens mostly use self-sealing knife edge furnace doors, that is, the knife edge made of flat steel is pressed against the processing surface of the furnace door frame t...

AI Technical Summary

Problems solved by technology

[0006] 1. Extruding only through the first mold and the second mold, the extrusion force is small, and the sealing performance is poor, so the molten metal cannot be effectively cast. After the casting is formed, the surface is prone to bubbles, and the practicability needs to be improved.

[0007] 2. Only one cavity is designed, so batch processing and molding of castings cannot be realized, which is not conducive to improving corporate income

[0008] 3. After the metal casting is formed, the first mold and the second mold need to be separated, and then the casting is taken out from the mold, which is time-consuming and laborious, and is very inconvenient
