What is the material of hydraulic cone rolling machine

As a key equipment used in the field of metal sheet processing to manufacture conical cylinders,the performance and service life of hydraulic cone rolling machines largely depend on the materials used in each component.Different components carry different functions and have different requirements for materials.Below,we will delve into the material situation of the main components of the hydraulic cone rolling machine.

The frame is the supporting body of the hydraulic cone rolling machine,which needs to withstand huge loads,vibrations,and possible impact forces during equipment operation.Therefore,it must have high strength,high rigidity,and excellent stability.In some hydraulic cone rolling machines with relatively low load-bearing requirements and small equipment scales,the frame is often made of Q235B ordinary carbon structural steel.This type of steel has good plasticity and weldability,making it easy to perform cutting,bending,and welding operations,and can meet basic structural support requirements.Moreover,Q235B steel has a lower cost,which helps to reduce the overall manufacturing cost of the equipment.However,its strength and hardness are relatively limited,and there may be some degree of deformation under high load and high strength working environments.

The rolling roller is the core working component of the hydraulic cone rolling machine,which directly contacts the metal sheet and achieves the rolling of the conical cylinder through rotation and extrusion.Therefore,the rolling roller needs to have high hardness,high wear resistance,good surface quality,and fatigue resistance.

For some hydraulic cone rolling machines that process ordinary carbon steel and low-alloy steel plates,9CrSi alloy tool steel is often used as the rolling roller.This type of steel contains a high carbon content and a certain amount of alloying elements such as chromium and silicon,and has high hardness and wear resistance.After appropriate heat treatment,the hardness of 9CrSi steel can reach HRC58-62,which can effectively resist the friction and wear generated during the rolling process of metal sheets.Meanwhile,9CrSi steel also has certain toughness and fatigue resistance,which can maintain good performance stability during long-term use.

The hydraulic system is the power source of the hydraulic cone rolling machine,providing pressure and power for various actions of the equipment.The material of hydraulic system components needs to have good pressure resistance,corrosion resistance,and sealing performance.

The transmission components are responsible for transmitting the power of the hydraulic system to the executing components such as the rolling roller,achieving the movement and rolling action of the equipment.The material of the transmission components needs to have good wear resistance,fatigue resistance,and transmission accuracy.
Chain is also a type of transmission component,commonly used in hydraulic cone rollers that require long-distance transmission.The material of the chain is generally made of 40Mn alloy steel.40Mn steel has high strength and toughness,and after heat treatment,it can achieve good wear resistance and fatigue resistance.When manufacturing a chain,it is necessary to perform stamping,stretching,heat treatment and other processes on the steel to process it into various parts of the chain.Then,through assembly and riveting processes,the various parts are connected into a complete chain.The 40Mn steel chain can withstand significant tensile and impact forces,ensuring the stability and reliability of transmission.
The material selection of hydraulic cone rolling machine is a complex process that comprehensively considers various factors such as equipment performance,usage environment,processing requirements,and cost.Reasonably selecting materials and adopting advanced manufacturing processes and heat treatment technologies can ensure the performance and quality of various components of the hydraulic cone rolling machine,thereby improving the overall performance and service life of the equipment and meeting the constantly developing needs of the metal processing industry.
