Cold rolled pipe mill is an equipment used for producing cold rolled pipes, mainly used for processing various specifications and materials of cold rolled pipe products. It usually consists of multiple components, including a feeding system, a curling system, a cold rolling system, a shaping system, and a cutting system.
The working principle of a cold rolling pipe mill is to roll metal strips through multiple rollers to obtain the desired shape and size without heating. This cold working method can improve the strength and hardness of the metal, while avoiding possible deformation and damage during the hot rolling process.
Cold rolled pipe mills are widely used in fields such as construction, machinery, automotive, aerospace, etc. The cold-rolled pipe products produced have the characteristics of smooth surface, precise size, and stable performance. In modern industrial production, cold rolling tube mills have become one of the indispensable and important equipment.

Equipment Introduction

1. A method of reciprocating motion driven by a chain or oil cylinder, in which the mobile car locks the head of the pipe or bar material to be processed using a fixture with locking and releasing functions, and performs linear drawing motion. The processed pipe or bar material is reduced in outer diameter through a mold, and the pipe material is reduced in wall thickness through an internal mold to meet the process requirements. The chain cold drawing machine consists of a main motor, reducer, trolley bed, drawing trolley, core rod bed, loading rack, unloading rack, lubrication system, electrical control system, etc. The hydraulic cold drawing machine consists of a hydraulic station, hydraulic cylinder, trolley bed, drawing trolley, core rod bed, loading rack, unloading rack, lubrication system, electrical control system, etc. The advantages of the chain cold drawing machine are fast speed and long stroke, and it is usually used in factories with high production requirements and long products. The advantages of the hydraulic cold drawing machine are smooth movement and low noise, and it is usually used for products with high precision requirements.
2. According to the driving mode, cold drawing machines are divided into two types: chain cold drawing machines and hydraulic cold drawing machines. According to their functions, cold drawing machines are further divided into reducing diameter and reducing wall cold drawing machines and expanding hole cold drawing machines. According to their motion trajectory, cold drawing machines are further divided into linear cold drawing machines and disc cold drawing machines.
