Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a sheet metal processing blanking mechanism. Background Art

[0002] In the prior art, after the sheet metal parts are cut by a cutting mechanism, the processed sheet metal parts and the cutting waste directly fall onto the conveying mechanism together, resulting in the need for workers to separate the scraps from the processed sheet metal parts and collect them, which increases the operating procedures of the workers and brings inconvenience to the workers.

[0003] To solve the above problems, the existing public patent (CN220426606U) discloses a sheet metal processing blanking mechanism, including a conveying mechanism and a bracket. The two brackets are fixedly connected to a side plate on one side of the outside, and a processing cavity is slidably connected between the outsides of the two side plates. A guide hopper is arranged below the outside of the processing cavity, and a screening cavity is arranged below the inner wall of the processing cavity. A baffle is inserted at the groove of the processing cavity, and a collecting box is fixed on one side of the outside of the processing cavity. The processing cavity is driven by a cylinder to reciprocate between the side plates on both sides, so that the screening cavity can screen the workpiece and the scraps, so that the scraps can directly fall into the guide hopper through the screening cavity, while the processed workpiece can still be retained in the processing cavity. The blanking mechanism can directly screen the workpiece and the waste, without the need for the staff to subsequently increase the operation process, which brings convenience to the staff.
