Description

Technical Field

[0001] The utility model relates to the technical field of single-arm hydraulic presses, in particular to a mold steering mechanism of a single-arm hydraulic press. Background Art

[0002] The single-arm hydraulic press has a C-shaped single-arm structure and is welded by submerged arc welding. After welding, it is vibrated to ensure that the body does not deform. The hydraulic system is located inside the body, with beautiful appearance and convenient operation. It is suitable for the correction of shaft parts and profiles and the press-fitting of shaft sleeve parts. At the same time, it can also complete the bending, embossing, sleeve shaping, and stretching of simple parts of sheet parts. It can also be used to press powder and plastic products with less stringent requirements. This series of products is suitable for use in industries such as machine tools, internal combustion engines, light textile machinery, shafts, bearings, washing machines, automotive motors, air-conditioning motors, electrical appliances, military enterprises, and assembly lines of foreign-invested enterprises.

[0003] At present, most single-arm hydraulic presses adopt the descending stamping operation mode. There are different bending grooves around the lower working model, which can be used for bending angle, depth or radius. During the operation, if multiple processes are to be performed, such as bending angle first and then stamping depth, it is necessary to switch the bending grooves during the work process, which requires rotating the working surface of the mold. The existing methods are mostly manual rotation of the lower mold, but the mold is large in size and heavy in weight, which not only consumes a lot of manpower, but also has low work efficiency. Therefore, we proposed a mold steering mechanism for a single-arm hydraulic press to solve the above problems. Utility Model Content
