Description

Technical Field

[0001] The invention relates to the technical field of stamping and forging equipment, and in particular to a stamping and forging equipment for flange production based on hydraulic pressure. Background Art

[0002] Hydraulic-based stamping and forging equipment is commonly used to process metal materials, especially for stamping, forging and forming processes. These equipment can meet the needs of various industrial fields for metal forming, processing and manufacturing through the high pressure and precise control provided by the hydraulic system, while improving production efficiency and product quality. The selection of suitable hydraulic equipment usually depends on the specific process requirements, the size and shape of the workpiece, and the production batch.

[0003] Flange is a common engineering part, widely used in pipeline connection, mechanical equipment and containers. It is usually used to connect the ends of two pipes, valves, pumps or other equipment and fasten them together by bolts. Its types are: Welding flange: used for welding to pipes or equipment, suitable for high pressure or high temperature conditions.

[0004] Wafer flange: used to be clamped at the end of the pipe and clamped with bolts.

[0005] Blind flange: used to close the end of a pipe or container, without a center hole, often used to test piping systems or where closure is required.

[0006] Slip-on flange: Usually used for lower pressure or lower temperature conditions, it is slipped into the pipe and welded to the pipe.

[0007] Threaded flange: has internal and external threads and is used to connect threaded pipes or valves.

[0008] Socket welding flange: welded on the pipe and used in conjunction with the flange.

[0009] Hydraulic flange stamping and forging equipment is used to produce various types of flanges, usually covering product requirements from small to large, different shapes and specifications. These equipment combine the high pressure and precise control of the hydraulic system to effectively process and form metal materials, ensuring the production of flange products that meet standards and quality requirements.

[0010] When traditional hydraulic flange stamping and forging equipment performs high-temperature flange stamping and forging, the high temperature may cause oxidation on the surface of the flange blank, resulting in an oxide layer. During the stamping and forging process, especially at the contact part of the die, the surface oxide layer may be peeled off due to contact pressure or shear force. At this time, since traditional hydraulic flange stamping and forging equipment is not convenient for timely cleaning of the oxide layer, metal chips and shavings may adhere to the flange surface or between the workpieces, affecting the surface quality and dimensional accuracy of the flange. If metal chips and shavings enter the hydraulic system or other key parts, it may cause unstable operation of the equipment or even damage key components of the equipment.

[0011] In summary, the prior art lacks a technology for automatically treating oxides for a certain hydraulic flange stamping and forging equipment. Summary of the invention
