Description

Technical Field

[0001] The utility model relates to the technical field of bushing production, in particular to a double-cylinder shaping machine. Background Art

[0002] The bushing is a matching part used outside the mechanical parts to achieve the functions of sealing and wear protection. It refers to a ring sleeve that acts as a gasket. In the field of valve applications, the bushing is inside the valve cover and is generally made of corrosion-resistant materials such as polytetrafluoroethylene or graphite for sealing. The copper bushing is generally made by rolling a rectangular copper blank. After the bushing is formed by stamping and rolling, it is necessary to use a shaping machine to shape the inner circle of the bushing to improve the cylindrical accuracy of the bushing. During the shaping process, the bushing is fixed in the shaping mold, and the shaping shaft of the shaping machine reciprocates along the axis of the bushing. The shaping shaft is inserted into the bushing, and the outer circumference of the shaping shaft abuts against the inner circumference of the bushing. Under the expansion action of the shaping shaft, the outer circumference of the bushing abuts against the shaping mold, thereby completing the shaping process of the bushing.

[0003] After the existing shaping machine completes the shaping of the bushing, it is necessary to release the bushing, replace the new bushing and fix the new bushing before the next shaping operation can be carried out. The time interval between the two shaping operations is long, which will lead to relatively low work efficiency and needs to be improved. Utility Model Content
