Description

Technical Field

[0001] The utility model relates to the technical field of mechanical surface engineering, in particular to a plane knurling processing device. Background Art

[0002] The knurling process is a mechanical processing process. By using a knurling tool to roll specific patterns on the surface of the material to be processed, it can enhance the anti-slip property, improve the appearance, and the fine knurled surface can also achieve surface hydrophobicity, preventing water droplets from splashing, scattering and aggregating together, reducing the residence time of water droplets on the surface. Applying this process to industrial materials can improve the rust prevention, anti-corrosion, anti-freezing and other properties of the material to be processed, increase the durability of industrial materials, and save the product maintenance cost.

[0003] There are usually three methods to achieve surface hydrophobicity in the prior art: First, using the femtosecond laser method to prepare the hydrophobic properties of the material surface. Although this method is efficient, it is relatively dangerous, especially with certain radiation, which is harmful to the human eye and skin, and it is not suitable for operators to be exposed to the processing environment for a long time; Second, using the electrical discharge machining method to prepare the hydrophobic properties of the engineering material surface. This method has low efficiency and long working hours, is not suitable for the preparation of large-area hydrophobic surfaces, and it is difficult to achieve mass production, which is not conducive to promotion; Third, using the etching method to prepare the hydrophobic properties of the engineering material surface. The waste liquid will pollute the environment and is not suitable for mass production. Moreover, most of the existing knurling technology processes and equipment are for processing cylindrical metals. Therefore, it is necessary to develop a device for knurling plane metals to achieve the surface hydrophobicity of plane metals. Summary of the Utility Model

Operate the first Z-axis moving mechanism 23 and the second Z-axis moving mechanism 24 to adjust the upper surface height of the workpiece to be processed 1 mm higher than the inclined surface of the knurling wheel, then operate the vise to clamp. Operate the Y-axis moving mechanism to align the knurling wheel with the front side of the upper surface of the workpiece to be processed. Then operate the X-axis moving mechanism to reciprocate horizontally, so that the workpiece to be processed passes through the knurling wheel forward and then passes through the knurling wheel backward. Operate the Y-axis moving mechanism to move forward a certain distance, which is the same as the thickness of the knurling wheel. In this way, until the rear side of the upper surface of the workpiece to be processed passes through the knurling wheel, the processing is completed.
