Perforating method for perforating one row of holes in hose

Abstract

The invention relates to a perforating method for perforating one row of holes in a hose. The perforating method includes the following steps that 1, a hose to be perforated is obtained, the diameterof the hose is 6-25 mm, and the two ends of the hose to be perforated are blocked after the hose to be perforated is filled with water; 2, the hose filled with water is placed in a liquid nitrogen cooling device to be cooled until the water in the hose is frozen to ice; 3, a to-be-perforated section of the hose is placed in a front-face perforating device to be perforated; 4, the perforated hose is moved forwards into a hose collecting device to wait for ice melting, and meanwhile, the next to-be-perforated section is placed in the front-face perforating device; and 5, the step 4 is repeated until the whole hose is perforated. A core mold is no longer needed for the front-face perforating device for the hose, the structure is simple, the perforating quality is good, the roundness of the holes can be guaranteed, and it is guaranteed that the hose cannot be broken through.

Description

technical field [0001] The invention relates to a drilling method for drilling a single row of holes in a hose. Background technique [0002] Hoses used in medical treatment and hoses used in refrigeration protective clothing need to be punched with a single row of holes on the hose, and hoses for drip irrigation also need to be punched on the non-opposite pipe wall. For the punching process of the hose, on the existing hose punching equipment (mainly punching machine) used in production, the punching die installed on the hose punching equipment is pressed down relative to the hose. movement to finish punching the hose. It is relatively simple to punch through the two pipe walls at one time, just squeeze the hose under the action of the punching machine, and get through the pipe walls on both sides at one time. [0003] When punching holes on the front side of the hose, the shape of the hole formed is regular, but a mandrel must be used. If the mandrel is not used, it is e...

Problems solved by technology

[0003] When punching holes on the front side of the hose, the shape of the hole formed is regular, but a mandrel must be used. If the mandrel is not used, it is easy to punch through the opposite pipe wall, and it is difficult to form a single row of holes; if the mandrel is used, the mold structure is more complicated. , and the washed down waste is difficult to remove

[0004] Another method is to flatten the hose, punch a semicircular hole on its side, and form a round hole after opening. The formed round hole is irregular, and the aperture is difficult to control, and the quality cannot meet the requirements.
