Description

TECHNICAL FIELD

[0001] The utility model relates to frame polishing technical field, specifically, relate to a plate frame polishing equipment. BACKGROUND

[0002] Frame workpiece is the important component of many products, such as furniture, door and window frame and the panel inside of some industrial equipment also needs plate frame to support and fix. Frame is the workpiece that is spliced by multiple square tubes. In the processing of frame workpiece, polishing is a crucial link, which directly influences the surface quality, precision of workpiece and the smooth progress of subsequent assembly. However, traditional manual polishing mode has many problems, which seriously restricts production efficiency and product quality.

[0003] In the processing of frame workpiece, traditional manual polishing mode has many significant problems. First, manual polishing is inefficient. Polishing workers need to spend a lot of time to process each part of frame workpiece one by one, which greatly prolongs the production cycle and makes it difficult to meet the requirements of modern industry for efficient production. Second, the quality of manual polishing is unstable. Due to the differences in technical level, working state and other factors of polishing workers, the polishing quality of different batches or even the same batch of frame workpieces is uneven. For example, it is difficult to achieve complete consistency in polishing intensity and precision, and some workpieces may be over-polished, damaging the surface of the workpiece, while the other workpieces may be under-polished, with high surface roughness. Third, manual polishing is labor-intensive. A large amount of dust and noise is generated during the polishing process, which seriously harms the health of workers. At the same time, long-term repetitive work is easy to make workers tired, increasing the safety risk in work. Finally, the labor cost is high. With the development of economy, the labor cost is rising, which makes the investment of enterprises in manual polishing larger and larger, seriously affecting the economic benefits of enterprises.
