Batch forming method for coke oven bolts

Abstract

The invention relates to the field of metal casting machining, and specifically relates to a batch forming method for coke oven bolts. The batch forming method for the coke oven bolts comprises a base, a die table, a controller, an extrusion mechanism and three lower dies, wherein the extrusion mechanism is arranged at the top of the base and used for carrying out die casting to form the bolts; the extrusion mechanism comprises a first pressing plate, a second pressing plate, an abutting assembly, two sliding assemblies, two traction assemblies and three upper dies; the three lower dies are arranged in the die table at equal intervals and used for containing molten metal, and two baffles are arranged between every two lower dies in an attached mode; the bottom of each baffle is fixedly connected with the bottom of the inner side of the die table; and the abutting assembly is electrically connected with the controller. According to the batch forming method for the coke oven bolts, a better extrusion effect and higher sealing performance are achieved, products are easy to form, bubbles are not likely to be generated on the surfaces after forming, and meanwhile, a simple discharging process, and time-saving and labor-saving material taking are achieved.

Description

technical field [0001] The invention relates to the field of metal casting processing, in particular to a batch forming method of a coke oven door bolt. Background technique [0002] Auxiliary equipment of the coke oven that opens and closes the openings at both 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 can push out the coke. The coke oven door is divided into organic side oven door and coke side oven 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 be inserted into the carbonization chamber for flat coal. The furnace door is composed of shell, lining brick, knife edge, horizontal iron and other components. Modern coke ovens mostly use self-sealing knife-edge furnace doors, that is, the knife edge made of flat steel is pressed tightly on the processing surface of 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
