Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts production, in particular to a cold extrusion device for processing a blank of an automobile pressure-limiting valve body. Background Art

[0002] In the automobile manufacturing process, the pressure-limiting valve body is one of the key components, and its quality and production efficiency directly affect the performance and manufacturing cost of the whole vehicle. The traditional pressure-limiting valve body blank processing method mostly adopts the forging process. However, although the forging processing method has a long history and is widely used, its inherent problems are gradually emerging. First of all, forging processing has limitations in the precision of raw material forming. Since the fluidity and deformation characteristics of metal raw materials are difficult to accurately control during the forging process, subsequent mechanical processing is often required to achieve the precision required by the design, which not only increases the processing cost and time, but also may lead to material waste. Therefore, we propose a cold extrusion device for automobile pressure-limiting valve body blank processing to solve the above problems. Utility Model Content

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

The auxiliary mechanism includes an air guide pipe, which is movably installed between the forming block and the workbench, and the upper end of the air guide pipe is located in the forming groove. A fan is installed at one end of the lower surface of the workbench, and the fan is connected to the air guide pipe. A connecting frame is clamped and installed on the rear side of the output end of the hydraulic cylinder, and the lower end of the connecting frame is connected to the air guide pipe.

[0006] Preferably, a sealing groove is provided at the inner lower end of the molding groove, a sealing plate is mounted in the inner part of the sealing groove, and the upper end of the air guide tube is connected to the sealing plate.

[0007] Preferably, a through hole is penetrated through the inner lower end of the sealing groove, and the air guide tube is movably installed in the through hole.

[0008] Preferably, a hose is installed at the air outlet of the fan, and the upper end of the hose is installed through the inner lower end of the air duct.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) In the utility model, the user places the raw material inside the molding groove, and then uses the hydraulic cylinder to push the extrusion block to cooperate with the molding groove to extrude the raw material, thereby improving the molding accuracy of the raw material and directly extruding the approximate shape of the finished product, reducing material damage, and facilitating the direct processing of the extruded finished product in the later stage, thereby improving the overall processing efficiency.
