When purchasing press equipment, it is necessary to identify the quality of the equipment from multiple angles to ensure that high-precision and high-durability equipment is purchased to avoid quality and maintenance problems encountered in future production.
The following are detailed identification steps:
1. Product accuracy identification
Testing and testing: During the test stage, observe whether the accuracy of the product meets the requirements of the drawing. If the product accuracy does not meet the standard, it is necessary to find out the reasons, such as whether the roller design is reasonable or whether the equipment debugging is in place. Unqualified accuracy will lead to subsequent production of scrap products, causing huge losses.
Stability test: By continuously running the equipment, observe the molding consistency and stability of the product. Any slight deviation may lead to a decline in product quality.
2. Judgment of the quality of shafts and rollers
Material and process requirements: The materials and processing technology of shafts and rollers determine their wear resistance and fracture resistance. High-quality equipment usually uses high-strength alloy steel and is heat-treated to increase durability.
Wear resistance after long-term use: Even if the accuracy requirements can be met in the early stage, shafts and rollers with unqualified quality will wear after long-term use, affecting the accuracy of the finished product. To avoid this situation, confirm whether the equipment is made of high-quality wear-resistant materials, and consult the equipment manufacturer about the service life and warranty period of the parts.
Preventive maintenance measures: Find out whether the manufacturer provides replacement parts and installation and commissioning services for shafts and rollers to reduce the difficulty of repair when the equipment is worn later.
3. Quality identification of transmission mechanism
Material and brand of parts: The transmission mechanism of the press includes gears, chains and bearings. These parts need to be durable and of guaranteed quality. Bearings of big brands and specially treated gears are often used in the transmission system to increase the overall life.
Wear inspection: Since the transmission mechanism is the most severely worn part of the press, you can ask the manufacturer whether it provides reinforcement measures or additional lubrication guarantees to ensure that it can still work stably under high-load operation.
Replacement and maintenance convenience: Once the transmission mechanism is damaged, it may need to be replaced as a set. Ask and confirm in advance whether it is easy to replace and debug to ensure that it can be easily operated if maintenance is required in the future.
4. Stability and automatic control of the whole machine
Stability and durability: Whether the equipment is stable and vibrates little during operation. A good cold roll forming machine can still operate stably under long-term high load, which can effectively avoid problems such as project shutdown.
Automation and humanized operation: Many high-end presses are now equipped with PLC control systems and automated configurations, such as one-button start and automatic adjustment functions, which can reduce human operating errors and improve production efficiency.
After-sales service and warranty support: Whether the equipment manufacturer provides comprehensive after-sales service, including emergency repairs, regular maintenance and professional technical support. This is crucial for the long-term normal operation of the press, avoiding production stoppages due to technical or parts problems in the later stage.
5. Detailed technical parameters and product design
Volume diagram and equipment drawings of finished products: Make sure that the equipment drawings provided by the manufacturer are consistent with your product design drawings. If necessary, the finished product drawings can be sent to the supplier to prevent the production equipment from not matching the actual needs.
Rationality of equipment design: A reasonable design not only helps the machine to run smoothly, but also facilitates subsequent maintenance. Ensure that the structural design is reasonable and the parts are easy to disassemble and maintain.
When choosing a cold roll forming machine, be sure to visit the manufacturer for a field visit to observe the actual operation of the equipment, and consult other users for feedback on their use, so as to fully understand whether the equipment quality is good enough, thereby reducing various hidden dangers in subsequent production.
