Problems solved by technology
The valve seat bushing is the main component of the valve seat. In the current technology, the valve seat bushing is generally made of cylindrical raw materials and formed by lathe turning. This kind of production not only has high manufacturing costs, but also wastes social resources, which is not in line with energy conservation and environmental protection. philosophy
Therefore, there is a need for an energy-saving and environmentally friendly valve seat bush processing technology that does not waste social resources, but there is no processing equipment suitable for this process that can preform the valve seat bush in the prior art

The invention belongs to the technical field of valve seat bush manufacturing devices and in particular relates to a pre-forming device of a high-temperature valve seat bush, which solves the technical problem that the prior art is not reasonable. A driving shaft and a driven shaft are arranged in parallel on a base; the driving shaft is connected with a driving mechanism which is capable of driving the driving shaft to rotate; a transmission mechanism through which the driving shaft can drive the driven shaft to rotate is arranged between the driving shaft and the driven shaft; a first formation wheel body is arranged on the driving shaft; a second formation wheel body is arranged on the driven shaft; the first and second formation wheel bodies are adjacently arranged, and a formation gap for the formation of an outwards turned edge on the end part of a cylindrical blank is formed between the first and second formation wheel bodies. Compared with the prior art, the pre-forming device of the high-temperature valve seat bush has the advantages that (1) the design is reasonable, the structure is simple and the valve seat bush can be preformed; (2) the operation is simple and the device can be used by workers conveniently.
Description
technical field [0001] The invention belongs to the technical field of valve seat bushing manufacturing equipment, and in particular relates to a high-temperature valve seat bushing preforming device. Background technique [0002] The valve seat is a detachable surface part in the valve, which is used to support the fully closed position of the valve core and constitute a sealing pair. Generally, the seat diameter is the maximum flow diameter of the valve. For example, the seat material of the butterfly valve is very wide, and all kinds of rubber, plastic, and metal materials can be used as the seat material, such as: EPDM, NBR, NR, PTFE, PEEK, PFA, SS315, STELLITE and so on. The valve seat bushing is the main component of the valve seat. In the current technology, the valve seat bushing is generally made of cylindrical raw materials and formed by lathe turning. This kind of production not only has high manufacturing costs, but also wastes social resources, which is not in ...
