Description

Technical Field

[0002] They are indispensable materials in manufacturing, used in various applications, from construction to automotive manufacturing to electronic devices. Metal sheets are usually made of metals such as aluminum, steel, and stainless steel, and have many advantages, such as high strength, good corrosion resistance, and strong plasticity. During the manufacturing process, metal sheets can be processed in various ways, such as cutting, bending, stamping, and welding, to meet the requirements of different designs and uses. For example, the body parts in automotive manufacturing, the casings in electronic devices, and the structural parts in industrial equipment are usually made of metal sheets. In addition, with the progress of technology, some special metal sheets, such as titanium alloy sheets and nickel-based alloy sheets, have begun to play an important role in high-tech fields such as aerospace, energy, and medical equipment, and are favored for their excellent performance characteristics. In short, metal sheets have an irreplaceable position in modern manufacturing. They not only provide structural support and aesthetic appearance but also provide key support for the functionality and durability of products.

[0003] Some metal sheets need to be leveled before use to prevent them from being unusable due to bending. However, the current leveling machines lack a limiting structure for metal sheets, which may cause the metal sheets to shift during leveling, thus affecting the leveling, and once the leveling structure of the current leveling machine is damaged, it is impossible or inconvenient to replace, thus affecting the service life of the device.

[0004] In view of this, in response to this technical problem, the present application proposes a hydraulic leveling machine. Content of the Utility Model
