Working principle and structural characteristics of roll forging machine

Roll forging machine is an equipment used for pre forging and final forging of forgings, and its working principle and structural characteristics are as follows:
1, Working principle
Roll forging machines use the rotation and extrusion force of the rollers to shape and process metal materials. Under the action of rollers, the metal material undergoes a series of rolling and deformation to ultimately obtain the desired shape and size.
2, Structural characteristics
Double column support mechanism: The overall design of the roll forging machine adopts a double column support mechanism, which uses two frames to support the upper and lower forging rollers for rotational motion. This design gives the equipment greater rigidity and stability, enabling high-precision forgings to be produced.
Multiple fan-shaped roller forging molds: Multiple fan-shaped roller forging molds can be installed between the upper and lower forging rollers to form the workpiece by rolling. The design of these molds depends on the specific shape and size requirements of the workpiece, and can achieve complex forming processing.
Adjustment mechanism for forging roller center distance and forging roller angle: The roll forging machine has a mechanism for adjusting the center distance and forging roller angle of the forging roller, which can adjust the center distance of the upper and lower forging rollers and the misalignment angle of the forging roller mold. This adjustment function can easily align and adjust the mold clearance and angle to meet the processing needs of different workpieces.
3, Equipment specifications
Roll forging machines come in various specifications, with a roll diameter range typically between 250-1250 millimeters and a corresponding roll forging force of 400-4000 kilonewtons. These specifications of equipment can meet the processing needs of workpieces of different sizes and weights.
4, Automation level
Roll forging machines can be used in conjunction with robotic arms or automatic devices to achieve automation in roll forging production. In large-scale roll forging production, mechanical arms are widely used to transport workpieces, improving productivity and reducing labor intensity.
5, Application field
The roll forging machine is suitable for producing various forgings, such as connecting rod, Fried Dough Twists drill, wrench, spike, hoe, pick and turbine blade. Due to its advantages such as simple equipment structure, stable production, low vibration and noise, roll forging machines have been widely used in the field of metal processing.
6, Operation precautions
When operating the roll forging machine, it is necessary to strictly follow the safety operating procedures to ensure the safety of personnel. This includes regular inspection and maintenance of equipment, ensuring that it operates in good working condition, and avoiding improper operations such as overload and overheating.
In summary, a roll forging machine is a device used for pre forging and final forging of forgings, with features such as a double column support mechanism, multiple fan-shaped roll forging molds, and a center distance and angle adjustment mechanism for forging rollers. Roll forging machines can achieve high-precision and high-efficiency forging processing, and have broad application prospects in the field of metal processing.
