In this context, hydraulic pressing tools play a crucial and undeniable role in the maintenance and repair processes, especially in industrial sectors. With the ability to provide pressure and robust force, hydraulic pressing tools contribute to improving work efficiency and optimize maintenance and repair processes.
This makes maintenance tasks quicker and more effective, reducing working time and optimizing human resources. Recognizing these important roles and with the permission and enthusiastic support of Ms Dương Thị Vân Anh and CODIA Industrial Solutions Company, we decided to explore and research the graduation project of our group with the topic: "Design, manufacture hydraulic press tool to support maintenance and repair for CODIA Industrial Solutions Company" to serve the production and maintenance needs of the company. The tasks our group has undertaken in the project include: - Studying the principles of hydraulic pressing. - Surveying the types of hydraulic presses currently on the market.
- Research punch and die - Designing and calculate finalizing the drawings. - Machining and ordering parts to proceed with assembly. - Testing, evaluating the product to record results and improve quality. TABLE OF CONTENTS Page MISSION OF THE GRADUATION PROJECT.
