Description

Multi-edge and multi-grinding-surface seal cutting and engraving dual-purpose knife

Technical Field

The utility model relates to the technical field of seal engraving knives, in particular to a multi-edge multi-grinding-surface seal cutting and engraving dual-purpose knife.

Background

The seal is used as stationery to be printed on a document to represent identification or signing, and is generally printed with pigment, is not stained with pigment, and is printed with a plane to form a concave-convex steel seal, and some of the seal is a wax seal printed on wax or fire paint and an envelope.

At present, the manufacturing of the seal still remains traditional manual carving tradition, and when the seal is carved, tool knives with different models are needed to be used, such as carving knives, knife sharpening, auxiliary carving knives and the like, and a carving person needs to frequently replace the tool knives to carry out carving, polishing and other operations, so that the use is inconvenient.

Meanwhile, the seal carving knife for carving stones cannot be used for carving articles such as wood, bones, leather and metals due to the fact that the knife is relatively blunt, and the carving can be performed only by the aid of quite sharp knives, so that the existing seal carving knives and knives used for carving are used separately and are not communicated with each other.

Therefore, the novel multipurpose engraving knife for engraving the seal is designed to be withdrawn, the main engraving knife, the auxiliary engraving knife and the polishing surface are integrated, the dual-purpose engraving knife is realized, the multipurpose engraving knife can be used for engraving other products such as woody products, jade products and leather products, the engraving and polishing tasks can be finished simultaneously only by one engraving knife, the tool knife does not need to be replaced frequently, the use of operators is facilitated, and the engraving efficiency of the seal and the engraving is improved.

Disclosure of Invention

The utility model aims to provide a multi-edge multi-grinding-surface seal cutting and carving dual-purpose knife, which solves the problems in the background technology.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

the utility model provides a many edges angle grinds face seal cutting, sculpture dual-purpose sword, includes that outside edges angle profile is square cutter body, and cutter body upper end is provided with the main knife cutting edge along the diagonal, and the both sides of main knife cutting edge are provided with supplementary blunt knife cutting edge along the diagonal symmetry, and the knife face of main knife cutting edge both sides is the first plane of grinding of symmetry.

As a further preferred embodiment of the present utility model: the lower side of the first grinding surface is provided with a second grinding surface.

As a further preferred embodiment of the present utility model: the second polishing surface is provided with one.

As a further preferred embodiment of the present utility model: the second polishing surface is provided with two.

As a further preferred embodiment of the present utility model: the joint of the first polishing surface and the second polishing surface is provided with a third polishing surface.

As a further preferred embodiment of the present utility model: the outline of the external edge angle of the cutter body is square.

As a further preferred embodiment of the present utility model: the third polishing surface is provided with two.

Compared with the prior art, the utility model has the beneficial effects that:

the diagonal straight line of the square cutter body material section is used as the main cutter edge of the cutter to grind and manufacture, so that the carving grinding knife with multiple edges and multiple grinding surfaces is generated, the material is saved, the weight is light and flexible, and the operation is convenient;

the two sides of the main cutter blade are auxiliary blunt cutter blades, so that the main cutter blade can be replaced for stamping, stamping and scraping the carving part, the service life of the main cutter blade is prolonged, and the service life of the carving cutter is further prolonged;

different from the traditional graver, the left and right edges of the main blade of the graver are sharp edges, so that the construction is facilitated, and the progress of the cutting edge and the surface of a carved object of the seal during construction is conveniently observed, and the sight line obstacle is reduced;

because the left and right sides of the main cutter blade of the engraving cutter are sharp blades, the cutting edge is erected up and down, any sharp blunt cutter blade can be used for carrying out seal cutting in pecking, scribing, screwing and other modes on the stamp, and the single engraving function of the traditional seal cutting cutter is changed;

through the sword face design of main knife cutting edge both sides is polished the face, can play the effect of polishing seal burr, designs the third simultaneously and polishes the face between first face and the second face of polishing, can polish according to the demand of polishing angle and polishing area, selects suitable face of polishing, has improved the flexibility of carving knife.

In conclusion, the seal cutting and engraving dual-purpose knife integrates the seal cutting, engraving, scraping (seal cutting) and polishing (such as wood, bone, copper and the like) functions of a plurality of knives, improves the applicability and flexibility and improves the working efficiency.
