Abstract

The utility model relates to the field of cutter design, in particular to a plate cutting knife. The plate cutting knife comprises a knife body. A knife edge is arranged on the knife body and of an arc-shaped surface hollowed towards the inside of the knife body. The knife edge is of the arc-shaped surface hollowed towards the inside of the knife body so that when the plate cutting knife is placed horizontally and cuts plates in contacting mode, a certain cut-in angle is always formed between the knife edge and the plates. Meanwhile, both ends of the plate cutting knife can be used to cut the plates, and therefore cutting speed is improved and the plates are stressed uniformly and do not shift.

Description

A kind of plate cutting cutter

Technical field

The utility model relates to the cutting tool design field, relates in particular to a kind of plate cutting cutter.

Background technology

The metallic plate that sheet material refers to forge more, rolling or casting forms, also often finger is made the flattened rectangular constructional material plate of normal size, can be used as the member on wall, ceiling or floor.

For sheet material being processed into the size of standard, usually can use cutting tool, wherein the most frequently used is cutting off machine, the parts that play crucial dissection in the cutting off machine are cutter.Existing cutter side and section and section are all rectangle, cutting knife is a horizontal plane, existing cutting off machine is in cutting thus, need to tilt certain angle and sheet material of cutter is tangent, the cutting stroke is relevant with the sheet material demanding criteria, reduce the cutting speed of every block of sheet material, also wasted a large amount of electric energy simultaneously thus, increased unnecessary cost.Wherein specially be, in the cutting metal plate, because the material of metallic plate itself is different, easily because unilaterally contacting cutting, cutter cause discontinuity in the time of plate cutting, cause thus the adverse consequences of sheet deformation or cutting skew, waste sheet material.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of cutting speed faster, stressed uniform plate cutting cutter.

In order to realize the foregoing invention purpose, the technical solution of the utility model is:

A kind of plate cutting cutter comprises blade, has the edge of a knife at described blade, and the described edge of a knife is shaped as to the arcwall face of blade sunken inside.

The utility model is shaped as to the arcwall face of blade sunken inside by the edge of a knife is set, so that the utility model is horizontal positioned contacts cutting with sheet material when, the edge of a knife has certain cut-in angle with sheet material all the time, the utility model two all can be cut simultaneously simultaneously, when having increased cutting speed, the sheet material stress equalization, be not offset.

Description of drawings

Accompanying drawing described herein is used to provide further understanding of the present utility model, consists of the application's a part, does not consist of to improper restriction of the present utility model, in the accompanying drawings:

A kind of side view that Fig. 1 provides for the utility model;

Fig. 2 is A-A schematic cross-section among Fig. 1.

The specific embodiment

Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.

Embodiment 1:

As shown in Figure 1 and Figure 2, the present embodiment discloses a kind of plate cutting cutter, comprises blade 100, has the edge of a knife 101 at blade 100, and the edge of a knife 101 is shaped as to the arcwall face of blade 100 sunken insides.

The above technical scheme that the utility model embodiment is provided is described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all will change on the specific embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.

Claims

1. a plate cutting cutter comprises blade, it is characterized in that:

Have the edge of a knife at described blade, the described edge of a knife is shaped as to the arcwall face of blade sunken inside.
