Description

Technical Field

[0001] The invention relates to the technical field of section steel processing equipment, and in particular to a synchronous chamfering and milling device for eight edges and corners of an H-section steel. Background Art

[0002] In the construction process of offshore oil platforms, H-beam is an important structural material, and its surface quality has a significant impact on coating adhesion and structural durability.

[0003] As an important material in the fields of construction and machinery manufacturing, steel sections have complex and diverse specifications, including different sizes, shapes and materials. This requires companies to frequently adjust equipment parameters to adapt to different specifications of steel sections when using synchronous milling equipment. Manual parameter adjustment is not only inefficient, but also prone to errors, because the processing parameters required for each specification of steel section may be different. Once the parameter setting is inaccurate, it will lead to a decline in processing quality and even damage to the equipment or steel section. This not only affects the production schedule, but also increases costs and quality risks.

[0004] In the traditional synchronous milling process, manual turning of steel sections and monitoring of the synchronous milling process are essential links. This not only requires a lot of labor, but may also lead to human errors and safety hazards. Manual turning of steel sections requires a lot of physical strength and time, increasing labor costs. At the same time, due to the uncontrollability of manual operation, operational errors are prone to occur, such as incomplete turning and inaccurate chamfering depth, which affects product quality. In addition, long-term manual operation may also cause worker fatigue, further increasing safety hazards.

[0005] Since the steel needs to be turned over multiple times for simultaneous milling and double-sided chamfering, the conditions for each chamfer (such as tool wear, machine adjustment, etc.) may be slightly different. This makes it difficult to maintain consistent quality of double-sided chamfering, resulting in dimensional deviation, uneven surface roughness and other problems. This not only affects the aesthetics and performance of the product, but may also reduce customer satisfaction and trust. In order to solve this problem, companies need to invest more time and energy in quality inspection and repair, which increases costs and time costs.

[0006] Traditional synchronous milling has limited functions and cannot complete double-sided chamfering in one go. This means that companies need to use two devices or perform multiple processing to complete a complete double-sided chamfering process. This not only limits the automation and intelligence level of the production line, but also increases the floor space and cost of the equipment. At the same time, multiple processing is also prone to the accumulation of errors and the decline of quality.

[0007] Frequent manual operation and equipment adjustment may increase safety hazards. Especially in the process of handling and turning heavy H-beams, workers need to bear greater physical and mental pressure, which is prone to safety accidents caused by operating errors or fatigue. In addition, the equipment itself may also have design defects or improper maintenance leading to safety hazards. These safety hazards not only threaten the lives of workers, but may also cause significant economic losses and legal risks to the company.

[0008] Therefore, in order to solve the above problems, it is urgent to design a synchronous chamfering milling device for eight edges and corners of H-beam. Summary of the invention
