Comb-like blade structure and using method thereof

Abstract

The invention discloses a comb-like blade structure and a using method thereof. The comb-like blade structure comprises a blade body. The blade body comprises a tool toothed plate, and a plurality of tool teeth are arranged on one side of the tool toothed plate. A tool tooth gap is reserved between every two adjacent tool teeth, and the bottom of each tool tooth gap is provided with a cutting edge face. The section of the tool teeth is trapezoidal, and the bottom edge of each trapezoidal tool tooth is a cutting edge face. The interval of the tool tooth gaps is gradually decreased from outside to inside. By means of the comb-like blade structure and the using method thereof, the shear force can be effectively reduced, the blade cutting efficiency is improved, stability of the internal structure of the blade can also be ensured after long-term operation, the situation that the operation quality is affected due to looseness of a blade can be effectively prevented, the failure rate in use is effectively reduced, and accordingly the whole equipment is long in service life, low in maintenance frequency and high in cutting quality. The comb-like blade structure is reasonable and simple, convenient to operate, high in practicability and low in production cost, the appliance range of the tool is effectively extended, and the comb-like blade structure can be widely applied to various fields; and the portion, from the tooth end to the tooth root, of each tool blade is gradually thickened.

Description

technical field [0001] The invention relates to a blade, in particular to a comb-shaped blade structure and a use method. Background technique [0002] The blade is a flaky object clamped on the cutter body, and it forms the cutting part of the cutter. Applied discipline: first-level discipline of mechanical engineering; second-level discipline of cutting tool; third-level discipline of cutting tool element. Processing tools, also known as cutting tools, most of the knives are used by machines, but there are also hand-used ones. Since the knives used in mechanical manufacturing are basically used to cut metal materials, the term knives is generally understood as metal Cutting tools, the tools used for cutting wood are called woodworking tools, and there is also a special type of tool used for geological exploration, well drilling, and mine drilling, called mining tools, in order to produce a back angle and see the tool and not regrind. Affects the tooth shape of the process...

AI Technical Summary

Problems solved by technology

[0003] In order to ensure the sharpness of pruning, general knives are designed with very narrow teeth, which are easy to break during long-term use. Frequent replacement of knives not only causes troubles for pruning, but also wastes resources. In order to save labor, some props are horizontal when making knives. The cross-sections are all flat, which saves labor, but in the process of use, when combing hair, the flat surface will cause more contact area than the curved surface, and the friction will increase, which is not conducive to hair trimming and is comfortable for the trimmed. In addition, under the technical conditions of the existing blade structure, there are still many defects and ignorance. The unreasonable design of some blades leads to the need for a large shearing force during the use of the blade, which reduces the blade. At the same time, when the blade is working for a long time, it is easy to cause the inside of the blade to loosen, and stable cutting cannot be achieved, resulting in uneven cutting strength, reduced cutting quality, and insufficient strength, which is very inconvenient; and the existing blade When the structure is cutting hair, the sharpness is not enough, and it is not easy to remove chips; when the blade is in use, the contact between the moving knife and the fixed knife will increase the friction, which increases the heat generation during work, which is not conducive to improving the blade's performance. life; and when the existing blade is in use, it will hurt the skin surface and hair, which is very inconvenient; the contact area between the moving knife and the fixed knife is reduced, the friction is reduced, thereby reducing the calorific value during work
