Embodiment Construction
[0033] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.
[0034] Such as figure 1 As shown, it shows that the present invention relates to a first preferred embodiment of a punching knife 100, the punching knife 100 has a blade portion 1 and a blade portion 2 for punching a honeycomb sandwich panel, The blade portion 2 is formed with a plurality of serrations, which are specifically large teeth 21 and small teeth 22 arranged in a staggered manner. The specific staggered arrangement can be seen in the figure: it is provided between two adjacent large teeth 21 A small tooth 22, and a large tooth 21 is also arranged between two adjacent small teeth 22; both sides of the large tooth 21 and the small tooth 22 are provided with blade lines, and the blade lines of the large teeth 21 are adjacent to each other. The blade line of the small tooth 22 is an intersecting line, an...

Abstract
The invention discloses a punching cutter which is provided with a cutter body part and a cutting edge part capable of punching a honeycombed battenboard. The cutting edge part is provided with a plurality of saw teeth. The saw teeth are big teeth and small teeth, which are arranged in a stagger mode. Both sides of the big teeth and the small teeth are provided with cutting edge lines. The cutting edge lines of the big teeth and the cutting edge lines of the small teeth are intersecting lines and cutter polishing spaces are formed at the crosspoints along the direction of the cutting edge lines of the big teeth towards the cutter body part of the small teeth in a sunken mode. When the cutting edge part is polished, an enough placement position can be provided for a polishing tool so that the part of the cutting edge part, which is close to the bottom, can also be sufficiently polished, thereby ensuring that the whole punching cutter has permanent machining quality.
Description
technical field [0001] The invention relates to the field of knives, and more specifically relates to a punching knife specially used for punching honeycomb sandwich panels made of paper plastic and metal foil. Background technique [0002] The honeycomb sandwich panel is generally composed of three layers of materials, the two end layers are made of paper plastic or metal foil material, and the middle layer is honeycomb paper core. The honeycomb paper core has the characteristics of a hexagonal honeycomb structure. Specifically, a continuous hexagonal paper honeycomb structure is produced by ordinary paper through a special processing procedure. Honeycomb paper core has the characteristics of light weight, high strength and high rigidity. It is a kind of packaging material with anti-buffering, heat preservation, heat insulation and sound insulation. Under the same thickness of raw paper, honeycomb paper core has higher compression resistance than ordinary corrugated paper,...
