Description

Technical Field

[0001] The present invention relates to the technical field of flange production, and specifically provides a high-strength large flange production device and a production method thereof. Background Art

[0002] Flange production is a systematic and complex process. Starting from raw material selection, materials such as carbon steel, stainless steel, and alloy steel are usually used. The quality of these materials directly affects the performance and service life of the flange. Through surface grinding treatment, not only can the aesthetics of the flange be improved, but its corrosion resistance can also be further enhanced. After completing the entire production process, the produced flanges are widely used in many fields such as pipeline connection and mechanical equipment.

[0003] In the traditional flange production, the drilling step is to, after completing preliminary processes such as forging and preliminary machining, according to the design requirements, use a drill press and a suitable drill bit to perform precise drilling operations on the formed flange blank. First, determine the position and diameter of the holes, and then, according to a specific drilling process, control parameters such as the drilling speed and feed rate to drill holes for installing bolts, connecting pipelines, etc. However, when using the above-mentioned device, it is difficult to drill multiple apertures of the flange simultaneously, resulting in a significant reduction in production efficiency. Because each hole needs to be drilled one by one, a large amount of time is consumed in operations such as hole position adjustment and drill bit replacement. It is difficult to guarantee the drilling accuracy. Multiple positioning and operations are prone to cumulative errors, affecting the overall quality of the flange. It also increases labor costs and labor intensity. Workers need to operate the equipment frequently and pay attention to the drilling process at all times. At the same time, it also reduces the equipment utilization rate, making it unable to fully exert its efficiency during the process of drilling each hole one by one, leading to an increase in production costs, which is not conducive to the enterprise to achieve efficient and low-cost large-scale production.

Place the flange to be drilled in the receiving groove, and remove the plug-in of the rotating seat (53) by using the plug-in assembly, so that the flange can fit with the limiting arc plate (6); S2, the flange is limited in the receiving groove by the rotating plate (51), and then the flange can be more stable during the drilling process by the cooperation of a plurality of anti-slip sleeves and the limiting arc plate (6); S3, driving the drilling machine (24) downward by means of the telescopic assembly so that the drilling machine (24) contacts the flange, and by means of multiple drilling machines (24) working synchronously, multiple apertures can be processed on the flange at the same time; S4, taking out the flange after drilling, and clamping the flange by a clamping assembly; S5. Finally, the clamped flange is rotated by the driving assembly so that the aperture at the bottom of the flange corresponds to the grinder. Through continuous rotation, the bottom of the flange can be effectively grinded, thereby improving the accuracy of the flange.
