[0002] Hoses are important components in modern industry and are widely used in air ducts and filtration, material handling, mechanical and power tools, and special medical and dental equipment. In order to facilitate the hose to achieve functions such as infusion and exhaust, it is usually necessary to punch holes in the hose.

[0003] Publication No. CN205735260U discloses a hose punching device, which has a through hole on a pad for the mold blade to pass through, and there is a one-to-one correspondence between the through hole and the punching mold. The hose to be punched is placed on the pad, and the press is started, so that the driving mechanism on the press drives the punching mold to move linearly downward relative to the pad until the end face position of the mold blade on the punching mold is lower than the bottom surface of the pad, and then the punching mold can be used to punch holes on the hose.

[0004] After the punching die in the above patent extends out of the through hole of the pad, holes are punched on both sides of the hose. That is, the existing punching equipment on the market is designed based on punching holes on both sides, and there is a lack of equipment for punching holes on one side of the hose.
