Punching die for removing bur of tubular product

Abstract

The invention relates to a punching die for removing bur of a tubular product. The punching die comprises a lower die seat and an upper die seat, the upper end of the lower die seat is horizontally provided with a guide groove, and a lower die push plate is slidably installed in the guide groove; a first inclined face is arranged on one side of the upper end of the lower die push plate, an upper die push plate is arranged on the position, on one side, of the lower end of the upper die seat, and a second inclined face matched with the first inclined face is arranged on one side of the lower endof the upper die push plate; the upper end of the lower die seat is provided with a guide block, a reset device is arranged between the lower die push plate and the guide block, the middle of the guide block is transversely provided with a sliding side cutting edge, and one end of the side cutting edge is fixed to the side surface of the lower die push plate; and a product positioning seat is arranged on the position, on one side of the guide block, of the upper end of the lower die seat, the product positioning seat and a product unloading plate arranged at the upper end of the product positioning seat are combined to form a cavity, and one end of the side cutting edge extends into the cavity. The punching die has the characteristics that operation is accurate, the product qualificationrate is increased, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a punching die for removing the separators of tubular products. Background technique [0002] The quality and precision of the punched parts mainly depend on the quality and precision of the punching die. Whether the punching die structure is reasonable and advanced directly affects the production efficiency and the service life of the punching die itself. [0003] Because the product is a tubular product, it is easy to produce a partition in the pipeline. In order to ensure the function of the product, the partition in the tubular product needs to be punched. However, the tubular product has slag bags and flow channels at both ends, and the overflow port of the slag bag is connected The inner wall of the product is flush. If the product is directly punched, it will easily lead to the product being scrapped. Therefore, it is necessary to optimize a punching die for removing the se...

Problems solved by technology

[0003] Because the product is tubular, it is easy to produce a partition in the pipeline. In order to ensure the function of the product, the partition in the tubular product needs to be punched. The inner wall of the product is flat. If the product is directly punched, it will easily lead to product scrapping. Therefore, it is necessary to optimize a punching die that removes the skin of the tubular product.
