Abstract

The invention discloses a reverse punching die with a spiral scraper, and belongs to the technical field of stamping dies. The reverse punching die comprises a lower die mechanism, wherein the lower die mechanism comprises a lower die base, a lower base plate and a lower die plate, the lower base plate is fixed on the lower die base, and the lower die plate is fixed on the lower base plate; a plurality of sliding guide sleeves are arranged on the lower die plate, a cylindrical clearance groove is formed in the lower die plate, a lower punch penetrates through the clearance groove, and the exterior of the lower punch is provided with a discharging mechanism in a sleeved mode; and a plurality of wedge-shaped blocks are arranged on the lower die plate. According to the reverse punching die with the spiral scraper, the lower punch is inserted into an upper punch male die, so that reverse punching of a workpiece from the lower portion of the workpiece is achieved, so that waste generated by punching is discharged from a waste outlet in the upper punch male die; and die operation is stable, burrs are reduced, when a stop ring makes contact with the lower die plate, a scraper mechanism is triggered to operate, so that the flanging burrs are thoroughly scraped away, the machining effect is good, burr reworking operation is not needed, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of stamping dies, in particular to a reverse punching die with a spiral scraper. Background technique [0002] The stamping die is a special process equipment for processing metal or non-metal into parts or semi-finished products in the cold stamping process. Some products will form flanging burrs on the edge of the punching area after the punching process of the stamping die. , affecting the processing quality of the product. [0003] At present, the stamping die is designed as a reverse stamping structure to remove burrs, but the effect of burr removal is not obvious, and it is still necessary to perform secondary cleaning of burrs after processing, which wastes manpower and material resources. Contents of the invention [0004] The purpose of the present invention is to propose a reverse punching die with a spiral scraper in order to solve the problem that the reverse punching die cannot completely rem...
