Problems solved by technology
[0007] Aiming at the problems in the prior art, the purpose of the present invention is to provide a high-precision flange production and processing technology to solve the existing problem. In the process of processing and forming the flange, the individual parts are processed and formed. This makes the production efficiency of the flange low, and it is difficult to ensure uniform product quality, and in the existing process of forming a flange with a larger diameter, it is difficult to quickly form a flange with a special-shaped structure on the surface. If half of the flange blank is processed at a time, it will make it difficult to mass-produce, and the technical problem that the quality is difficult to guarantee in the process of mass production

Embodiment Construction
[0048] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific drawings. It should be noted that, in the case of no conflict, the embodiments and Features in the embodiments can be combined with each other.
[0049] see Figure 1-10 , is a schematic diagram of the overall structure of a high-precision flange production process;
[0050] A high-precision flange production and processing technology, including the following steps:
[0051] S1. Blank production: when the metal blank is heated to 1150°C by high temperature, it is placed on a forging machine for forging, and the metal blank is forged into a flange blank with a circular hole in the middle;
[0052] S2. Blank processing: The flange blank obtained in step S1 is extruded at a temperature of 1000°C. By supporting the inner wall of the round hole in the middle of th...

The invention provides a high-precision flange plate production and processing technology, which relates to the technical field of flange plate production and processing, and includes the following steps: S1. Blank production: after heating the metal blank to a high temperature, place it on a forging machine Forging, the metal blank is forged into a flange blank with a circular hole in the middle; S2, blank processing: the flange blank obtained in step S1 is extruded, and the flange blank is formed by forming a circular hole in the middle of the flange blank. The inner wall is supported, and the outer circular surface of the flange is rolled and squeezed by a rotating pinch roller; the second righting grippers on both sides of the present invention are pushed by the corresponding second electric push rod Expanding and contracting, so that the second righting clamp can be retracted adaptively after the inner diameter and outer diameter of the flange blank are gradually increased after being squeezed, so that the second righting splint can be adjusted according to the outer circular surface of the flange For effective straightening and chip removal.
Description
technical field [0001] The invention relates to the technical field of flange plate production and processing, in particular to a high-precision flange plate production and processing process. Background technique [0002] Flanges are referred to as flanges for short, and they are just a general term. They usually refer to opening several holes for fixing on the periphery of a disc-like metal body for connecting other things. This thing is widely used in machinery, so it looks strange, as long as it looks like it is called a flange. [0003] During the production and processing of the flange, the metal blank is often forged, and then the metal blank is hot-pressed. At present, the patent number CN02133268.1 discloses a flange processing and forming process, which is characterized in that it uses 1650-1700 The molten steel smelted at ℃ is subjected to centrifugal casting to produce the prototype of the flange blank. The centrifugal casting temperature is 1520-1550℃. 10-48 h...
