In the forging industry, the servo forging press has become an indispensable equipment, which can solve the problem of insufficient strike energy and improve the quality of forging. This paper will deeply discuss the role of servo forging press in ensuring the quality of forgings.

First, the role of servo forging press

The servo forging press is an advanced forging equipment, which uses a servo motor drive system to precisely control the strike energy, speed and position. Compared with traditional hydraulic forging presses, servo forging presses have higher energy utilization and faster response speed, enabling efficient striking and precise control.

During the forging process, the servo forging press can generate up to thousands of tons of pressure, allowing the forging to complete the deformation process in a short time. At the same time, through the feedback control of high-precision displacement sensor and pressure sensor, the energy and speed of each strike can be accurately controlled to ensure that the forging is fully deformed. In this way, quality problems caused by insufficient strike energy can be avoided, and the quality and performance of forgings can be improved.

Second, the causes and effects of insufficient strike energy

Insufficient strike energy is one of the common problems in forging process. It is usually caused by:

Equipment failure: such as leakage of hydraulic system, insufficient pressure of oil pump, etc. Improper setting of process parameters: such as the impact, speed and time parameters are set unreasonable.

Improper operation: such as insufficient skill level of the operator, non-standard operation, etc. Insufficient strike energy will have an adverse impact on forging, mainly in the following aspects:

Insufficient forging deformation: resulting in uneven internal organization and mechanical properties, affecting product quality.

Residual stress: In the subsequent processing and use process, residual stress may lead to cracks, deformation and other problems.

Increase scrap rate: Due to insufficient strike energy, forgings may have cracks, deformation, etc., resulting in an increase in scrap rate and increased production costs.

Third, servo forging press solutions

The servo forging press solves the problem of insufficient strike energy by the following measures to ensure the quality of the forging:

Improve equipment maintenance: regularly maintain the equipment, check whether the hydraulic system leaks, oil pump pressure is sufficient, etc., to ensure the normal operation of the equipment.

Optimize process parameters: According to different forging process and forging requirements, reasonably set parameters such as striking force, speed and time to ensure sufficient striking energy.

Improve operation skills: Train operators to improve their skill level and ensure standard operation.

4. Practical application cases

An automobile manufacturing enterprise uses the traditional hydraulic forging press to produce engine block, which often has the problem of insufficient striking energy, resulting in unstable cylinder quality. To solve this problem, the company introduced a servo forging press. By improving equipment maintenance, optimizing process parameters and improving operating skills, the quality of the cylinder block has been significantly improved, the specific data is as follows:

Improved product pass rate: After using the servo forging press, the product pass rate increased to 98%, compared to 70% before a significant increase. Scrap rate reduction: After using the servo forging press, the scrap rate of the cylinder block is reduced by 20%, reducing the production cost of the enterprise.

Improved production efficiency: After using the servo forging press, the production efficiency of the cylinder block is increased by 15%, which improves the production capacity of the enterprise.

The servo forging press has significant advantages in solving the problem of insufficient striking energy and guaranteeing the quality of forging parts. By improving equipment maintenance, optimizing process parameters and improving operation skills, the potential of servo forging press can be fully brought into play, and the quality and performance of forging parts can be improved. For the forging industry, the use of servo forging presses has become a necessary choice, helping to improve the production efficiency of enterprises and reduce production costs.
