Automatic locking device for core roller of ring rolling machine

Abstract

The invention relates to the technical field of mechanical equipment, in particular to an automatic locking device for a core roller of a ring rolling machine. Through automatically locking and fixingthe core roller, the physical strength and the time spent when a bolt is adopted for fastening can be effectively saved, the locking mode of the core roller is simplified, the installation time of the core roller is shortened, quick disassembly and assembly of the core roller are facilitated, the working efficiency is improved, meanwhile, the firmness of the core roller is improved, the occurrence of the phenomenon that the core roller falls off due to the fact that the bolt is loosened when the bolt is fastened is avoided, the safety of the equipment is improved, and practicability and reliability are improved. The automatic locking device for the core roller of the ring rolling machine comprises a fixing column, three sets of first push plates and three sets of second push plates, wherein the top of the fixing column is installed on an external ring rolling machine; an inserting hole is formed in the middle of the bottom end of the fixing column in a communicating mode; the lower side of the inner wall of the inserting hole is a conical surface; three sets of installing grooves are annularly and evenly formed in the lower side of the outer wall of the fixing column in a communicating mode; the inner sides of the three sets of installation grooves communicate with the inner part of the inserting hole; and the upper sides of the three sets of first push plates are respectivelypositioned in the three sets of installation grooves.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to an automatic locking device for ring rolling core rolls. Background technique [0002] As we all know, the ring rolling machine is mainly to squeeze the ring-shaped workpiece and make it plastically deformed, so as to obtain the product of the required specification. The core roller on the ring rolling machine is mainly to position and squeeze the workpiece. The existing core roll During assembly, multiple sets of bolts are usually used for fastening. However, when this method is used, the fastening method of the core roll is more cumbersome, the physical strength of the workers is greater, the time required for fastening is longer, the work efficiency is low, and it is not easy to fix The core roll is replaced quickly, and the core roll is fastened by bolts, which has poor firmness, and the bolts are prone to loosening and the core roll falls off when the time comes...
