Barnaul K0034 cold forging press - description

Knuckle joint cold extrusion press Barnaul K0034 — 250 ton (ID:S78539) is press equipment designed for metal forming under pressure without preheating the workpiece. Cold stamping ensures high dimensional accuracy, surface finish, and increased strength of finished parts due to work hardening. The press is built for substantial loads, since the deformation resistance of cold metal is considerably higher than that of heated metal.

Cold forging press Barnaul - technological processes and operations

Forging The process of plastic deformation of metal, in which the workpiece changes shape under the impact of blows or static pressure. During forging, the metal structure is densified, internal inhomogeneities are eliminated, and the mechanical properties of the material are improved. As a result, forged products are distinguished by high strength and reliability when operating under significant loads. Forging is used both for producing finished parts and for preparing workpieces for subsequent stamping.
Coining Under enormous pressure, the die is pressed into the workpiece, forcing the metal to distribute into the smallest recesses of the tool. As a result, clear reliefs, inscriptions, or patterns are formed on the surface with high accuracy. The metal fills all details of the die, fully reproducing its geometry. Used in the production of coins, medals, and precision parts where relief clarity and dimensional accuracy are essential.
Calibrating A finishing operation that brings the forging to precise dimensions. The workpiece is placed in a calibration die, where under pressure its surface is leveled and the geometry is brought to the specified tolerances. This process eliminates minor shape distortions left after previous operations. As a result, the part receives stable dimensions and a smooth surface without additional machining.
Extrusion Shaping is achieved by forcing metal through the opening of a die (stamp), as a result of which the workpiece acquires the specified cross-section along its entire length. The process ensures high geometric accuracy and surface quality of the resulting products.
