Abstract

A novel staving knife comprises a knife handle and a knife body. The knife body is inserted into a knife handle structure through a fixed connecting base, an active face is arranged at the front end of the knife body, two symmetric triangular chisel teeth projecting forwards are arranged on the front end face of the active face, 120-degree oblique angles are formed on active faces on two sides of a chisel tooth structure, a section of the whole active face is transited backwards from the chisel teeth to form a symmetric arc surface, the height of the symmetric arc surface is 8-10mm, the active face is continuously transited to the knife body through a smooth surface, a hard tungsten alloy layer is punched on the whole symmetric arc surface of the knife body and tooth surfaces of the chisel teeth, and the thickness of the hard tungsten alloy layer is 100-300 micrometers. The novel staving knife is simple in structure and convenient to machine, and specific cross sections and hole structures can be directly and efficiently machined.

Description

A kind of novel cutter of punchinging

Technical field

The utility model relates to engraving tool, is specially a kind of novel cutter of punchinging that can process at stone matter material surface wooden and that hardness is lower.

Background technology

In engraving tool, the cutter of punchinging is used for as chisel a kind of the special cutter of one that carries out hole processing at material surfaces such as wooden, beautiful matter, Shi Zhi.Traditional cutter of punchinging generally includes handle of a knife and blade, and its handle of a knife is wooden strip structure, and front end is by the fixing blade of plug-in mounting mode, and blade is the rectangular flat structure of cross section, and cutting edge is the straight or basil that slightly inclines laterally.The cutting edge of the chisel structure of this structure is owing to being horizontal straight structure, other cutting edge is not driven in both sides, thereby in grooving process, can not damage groove both sides, thereby can only processing plane, and in the process of punchinging, can only process several times with chisel, the shape processing is also difficult to meet normal requirement; Processing time consuming effort, and can not carry out deep hole machining, technique creator has been caused to very large puzzlement.

Utility model content

The technical problem that the utility model solves is to provide a kind of novel cutter of punchinging, this cutter of punchinging not only can be used for processing the chamfering of right angle, arc, plane groove, arc groove and various shapes, also be suitable for carrying out deep hole machining at stone matter material surface wooden and that hardness is lower, to solve the shortcoming in above-mentioned background technology.

The technical problem that the utility model solves realizes by the following technical solutions:

A kind of novel cutter of punchinging, comprise handle of a knife and blade, wherein, blade is inserted on Knife handle structure by fixed connecting base, blade front end arranges sword face, in face of described sword, end face goes forward to dash forward two symmetrical triangles cutter teeth, on two side edge faces of cutter toothing, be provided with the oblique angle of 120 °, and after cutter teeth directional, be transited into a symmetrical arcwall face in a tangent plane part of whole sword face, the height of symmetrical arcwall face is 8 ~ 10mm, be shiny surface continuous transition from sword towards blade part, simultaneously, the whole cambered surface of symmetrical arcwall face and the flank of tooth part upper punch of cutter tooth at described blade are pressed with one deck tungsten hard alloy layer, the thickness of this tungsten hard alloy layer is 100 ~ 300 μ m.

In the utility model, the addendum angle of described two triangles cutter tooth is 120 ° ~ 150 °.

In the utility model, the thickness of the tungsten hard alloy layer in the flank of tooth part of described cutter tooth is preferably 200 ~ 300 μ m.

In the utility model, in the blade part on described sword face top, be processed with file face.

Beneficial effect: the cutter top of punchinging of the present utility model is provided with the bidentate shape machined surface that high-abrasive material is made, can cut a hole to add at chisel and treat machined surface man-hour and destroy in advance, make machined surface be more prone to processed, simultaneously, utilize bidentate shape machined surface to coordinate the symmetrical arcwall face at sword face rear portion, can carry out quickly and easily the hole processing of material surface; In addition, this cutter of punchinging can also use as common plane chisel, makes the craftsman can be by the processing that is used to material surface to carry out the chamfering of right angle, arc, plane groove, arc groove and various shapes to two tooth-shape structure sword faces.

Brief description of the drawings

Fig. 1 is the schematic diagram of the utility model preferred embodiment.

Wherein: 1-handle of a knife, 2-fixed connecting base, 3-blade, 4-file face, 5-sword face.

Detailed description of the invention

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to the preferred embodiment of a kind of novel cutter of punchinging of Fig. 1, in the present embodiment, comprise handle of a knife 1 and blade 3, blade 3 is inserted on handle of a knife 1 by fixed connecting base 2, and comprises sword face 5 and file face 4 in described blade 3 parts.

In the present embodiment, sword face 5 front ends are extruded with two triangle cutter teeth, two cutter teeth are symmetrical, on two side edge faces of cutter tooth, be provided with the oblique angle of 120 °, and after cutter teeth directional, be transited into a symmetrical arcwall face in a tangent plane part of whole sword face, the height of this symmetrical arcwall face is 8mm, is shiny surface continuous transition from sword towards blade part, and is pressed with in its cambered surface upper punch the tungsten hard alloy layer that a layer thickness is 100 μ m.

In the present embodiment, the addendum angle of described two triangles cutter tooth is 120 °, and on the sword face of cutter tooth tooth top, to be processed with a layer thickness be 200 μ m tungsten hard alloy layers.

More than show and described general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
