The technical purpose of the invention is realized by the following technical scheme: the utility model provides a curved knife external mold, is including inside cavity setting and is used for holding the body of establishing the curved knife centre form, the body with curved knife centre form clearance fit, the body lateral wall is equipped with feed inlet and discharge gate, the lateral wall of body is equipped with the cutting out incision of intercommunication discharge gate.

Preferably, the inner bending cutter mold is a bending cutter shaft, the bending cutter shaft is provided with a cutter hole for a cutter material to pass through, and the body is a bending cutter cylinder in clearance fit with the bending cutter shaft.

Preferably, the cutting notch is obliquely arranged from one side far away from the discharge hole to one side close to the discharge hole.

Preferably, the cutting cuts are V-shaped.

Preferably, the cutting slit is trapezoidal.

Preferably, the cutting cuts are triangular.

In conclusion, the invention has the following beneficial effects: when the knife material is bent, the knife material firstly passes through the bent knife inner die through the feeding hole of the body and protrudes out of the discharging hole, at the moment, the cutting notch is positioned at one side of the knife material, and then the bent knife inner die and the body move relatively to make the discharging hole and the bent knife inner die staggered, so that the effect of bending the knife material is achieved;

when the knife material is cut, the cutting opening is positioned below the knife material protruding from the inner curved knife mold through the movable outer curved knife mold, and then the inner curved knife mold and the body move relatively to make the discharge opening and the inner curved knife mold staggered, so that the effect of cutting the knife material is achieved;

the outer die of the bending knife can realize bending of knife materials and cutting of the knife materials, production efficiency is improved, and production cost is reduced.

Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element.

It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, as used herein, refer to an orientation or positional relationship indicated in the drawings that is solely for the purpose of facilitating the description and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and is therefore not to be construed as limiting the invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

The utility model provides a curved knife external mold, refers to fig. 1 to 4, is including inside to be the cavity setting and is used for holding the body 2 of establishing curved knife internal mold 1, body 2 with curved knife internal mold 1 clearance fit, the body 2 lateral wall is equipped with feed inlet 21 and discharge gate 22, the lateral wall of body 2 is equipped with the cutting edge 23 of intercommunication discharge gate 22, cutting edge 23 border is equipped with cuts the sword (not shown in the figure).

When the knife material is bent, the knife material firstly passes through the curved knife inner die 1 through the feeding hole 21 of the body 2 and protrudes out of the discharging hole 22, at the moment, the cutting opening 23 is positioned at one side of the knife material, and then the curved knife inner die 1 and the body 2 move relatively, so that the discharging hole 22 and the curved knife inner die 1 are staggered, and the effect of bending the knife material is achieved;

when cutting the knife material, the cutting cut 23 is positioned below the knife material protruding from the curved knife inner die 1 through the movable curved knife outer die, and then the curved knife inner die 1 and the body 2 move relatively to make the positions of the discharge port 22 and the curved knife inner die 1 staggered, thereby achieving the effect of cutting the knife material;

In this embodiment, the curved knife inner die 1 is a curved knife shaft, the curved knife shaft is provided with a knife hole 11 for a knife material to pass through, and the body 2 is a curved knife cylinder in clearance fit with the curved knife shaft. Specifically, an annular groove is formed in the circumferential direction of the inner wall of the cutter bending barrel, so that a space for bending the cutter material is reserved when the cutter material of the circular die is bent. Certainly, according to actual conditions, an annular groove can be formed in the outer wall of the bending knife shaft, and a knife material bending space can be reserved when the round die knife material is bent.

When the knife material is bent, the knife material firstly passes through the knife hole 11 through the feeding hole 21 of the body 2 and protrudes out of the discharging hole 22, at the moment, the cutting notch 23 is positioned at one side of the knife material, and then the bending knife inner die 1 and the body 2 are relatively rotated, so that the discharging hole 22 and the bending knife inner die 1 are staggered, and the effect of bending the knife material is achieved;

when cutting the sword material, along the axial slip curved knife external mold of curved knife centre form 1 for cut out 23 and be located the below from the convex sword material of curved knife centre form 1, later make curved knife centre form 1 and body 2 relative rotation, make discharge gate 22 and curved knife centre form 1 position phase-to-phase, thereby cut sword butt sword material, reach the effect of cutting the sword material.

Specifically, the cutting notch 23 is obliquely arranged from one side far away from the discharge hole 22 to one side close to the discharge hole 22. In the present embodiment, the cutout 23 has a V-shape. Of course, the cutting edge 23 may also be trapezoidal or triangular, depending on the actual situation.
