Description

Technical Field

[0001] The utility model relates to the technical field of die-casting, in particular to an oil pressure manual stamping integrated machine. Background Art

[0002] The manual stamping machine uses a hammer to hit the mold to add force to the blank, and then uses the impact force to create a pattern on the surface of the blank; this stamping machine originally came from foreign coin exhibitions, mainly to attract customers' attention and traffic. The disadvantage of the early stamping machine was that after the hammer hit the mold, the mold or mold parts would bounce out, which could cause damage to the surrounding onlookers or the ground.

[0003] The hydraulic stamping machine uses a hydraulic cylinder or hydraulic jack to add force to the mold. In the past, this hydraulic system and the entire machine frame were relatively large, ranging from tens of tons to thousands of tons, and the total weight of the machine also ranged from hundreds of kilograms to tens of tons. It was mainly used in professional commemorative coin stamps and jewelry factories. This type of equipment is professionally called a hydraulic press or a hydraulic press. It is driven by three-phase electricity, has high power, high noise, high weight, and is not easy to move. For handicraft workshops, stores, or home DIY scenes, this large-scale equipment that requires three-phase power is almost impossible to use.

[0004] The existing hand stamping machine only uses manual hammering to hit the printing mold and has no hydraulic function. Therefore, a new stamping machine that effectively combines hand stamping and hydraulic pressure is needed. Utility Model Content
