Description

Technical Field

[0001] The invention relates to the technical field of mechanical engineering, in particular to a two-stage quick-release blanking device for a punching machine. Background Art

[0002] A punch press, also known as a stamping machine or a press machine, is a mechanical processing equipment that applies pressure to a material to cause it to plastically deform or separate, thereby obtaining a desired shape and size. Two hoppers are generally provided below the punch press. The workpiece can fall directly into the hopper after being dropped through the hopper at the bottom of the punch press. Since the hopper is directly below the punch press, the workpiece can quickly fall into it after being dropped. However, the funnel in the prior art is an integrated non-detachable structure. After long-term use, impurities such as dust, oil, and metal debris are very likely to accumulate inside the funnel. These impurities will not only affect the patency of the funnel, but may also cause pollution to the workpiece. In addition, when the hopper is full, it is necessary to manually switch the hopper, and when the hopper is full, it is also necessary to manually close the hopper to stop feeding. In this way, personnel must be specially arranged to always pay attention to the status of the hopper in order to perform manual switching and closing operations, which undoubtedly increases the demand for labor and thus increases labor costs.
