Abstract

The invention discloses a die protection device for cold forming of short-rod parts, and relates to the technical field of cold upsetting. The die protection device comprises a dismounting ring, a mounting structure is arranged at one side of the dismounting ring, four sleeves are mounted at the periphery of the other side of the dismounting ring, oil storage boxes are mounted at the top ends of the sleeves, oil injection structures are arranged in the oil storage boxes, fixing rings are arranged at one sides of the sleeves, a plurality of grooves are formed in the inner walls of the fixing rings, guide blocks are slidably connected into the grooves, locking wheels are installed at one sides of the guide blocks, and one ends of the locking wheels extend to one sides of the fixing rings. Tension springs are lengthened through guide plates, the tension springs provide a recovery force, equivalently, the counter-acting force of a part on a die is increased, the situation that a short-rod bolt adheres to the die is greatly reduced, efficiency is guaranteed, and the problem that the short-rod bolt adheres to the die easily is solved.

Description

technical field [0001] The invention relates to the technical field of cold heading, in particular to a mold protection device for cold forming of short rod parts. Background technique [0002] The cold heading process is a processing method that uses the plastic deformation of metal under the action of external force and forms the required parts with the help of a mold. It does not generate cutting metal pressure and is very suitable for short rod parts such as bolts and screws. However, after these parts are formed, due to their own light weight, they are easy to stick to the mold, which affects production efficiency and production quality. In view of this, in-depth research aimed at the above problems led to this case. Contents of the invention [0003] The purpose of the present invention is to provide a mold protection device for cold forming of short rod parts, so as to solve the problem of adhesion between the parts and the mold mentioned in the above background tec...
