Abstract
The invention discloses a tool bit of a trimming die. The tool bit comprises a tool bit body, wherein the tool bit body is provided with a fixing hole, and a cutting edge is opened at the bottom of the tool bit. The tool bit is characterized in that the cutting edge is of a 90 degree inclined angle formed by the side surface and the bottom surface of the tool bit body. The tool bit has the advantages of simple structure and convenience of use and can prolong the service life of the cutting edge and reduce the punching rejection rate of products.
Description
Technical field
The present invention relates to mould applications, especially a kind of edger cutter head.
Background technology
Edger is the edge that utilizes punch trimming operation part, makes it have the diel of certain altitude, diameter and shape.Edger is mainly used in the edge of finishing drawing part, makes end face smooth attractive in appearance, is convenient to next step assembling.Edger is widely used in fields such as machine-building, auto parts production, beverage bottle processing, securing member mould be supporting.The edger of existing alloy die cast blank dead head machinery removal utilizes cutter head to carry out edger as shown in Figure 1.The problem that prior art exists is: 1. edge of a knife front end is very sharp, and intensity is very low, easily collapses to lack to scrap; 2. in the edge of a knife use, the cutting edge of a knife or a sword mouth is easy to rust, the cutting effect variation; 3. according to physical knowledge, in the time of knife edge cutting, knife back extruding dead head becomes the situation of breaking dead head off with the fingers and thumb down, and section is torn and lacked material as a result, casts aside the wicker that tool marks are arranged just as hand, it is very smooth that tomography begins the place, the inner again rule of just tearing into.
Summary of the invention
The present invention seeks to: provide a kind of simple in structure, easy to usely can prolong edge of a knife service life, reduce the edger cutter head of the die-cut scrappage of product.
Technical scheme of the present invention is: a kind of edger cutter head, comprise the cutter head body, and described cutter head body is provided with fixing hole, and cutting edge is opened the bottom at cutter head, it is characterized in that, and described cutting edge is the cutting edge of the formed 90 degree angles in cutter head body side and bottom surface.
Further, described bottom surface is trapezoidal, the cutting edge of the 90 degree angles that described trapezoidal bottom surface and cutter head body side form.
Further, in the described fixing hole buffer unit is arranged.
Further, described buffer unit is a spring.
Advantage of the present invention is:
1. strengthened the intensity of the edge of a knife greatly;
2. the wearing and tearing of edge of a knife cutting edge have been slowed down;
3. edge of a knife cutting, the power that the knife back is not broken off with the fingers and thumb, integral body are subjected to the vertical dead head of force direction plane, and the edge of a knife and supporter are staggered to be sheared, and section is smooth.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described:
Fig. 1 is the edger cutter head schematic diagram that uses at present.
Fig. 2 is an edger cutter head schematic diagram of the present invention.
Fig. 3 is an edger cutter head schematic diagram of the present invention.
Wherein: 1 cutter head body; 2 processed products; 3 fixing holes; 4 cutting edges.
The specific embodiment
Embodiment 1: a kind of edger cutter head as shown in Figure 2, comprise cutter head body 1, and described cutter head body is provided with fixing hole 3, and cutting edge 4 is the cutting edge of the formed 90 degree angles in cutter head body side and bottom surface.During duty, cutter head is fixed on the cutting equipment by fixing hole, alloy die cast blank to be processed is fixed, cutter head presses down, the edge of a knife carries out edger to alloy die cast blank dead head, owing to cutting edge 4 is the cutting edge of the formed 90 degree angles in cutter head body side and bottom surface, can strengthen the intensity of cutter head, slow down the wearing and tearing of cutting edge, increase the service life.
Embodiment 2: a kind of edger cutter head as shown in Figure 3, comprise cutter head body 1, and described cutter head body is provided with fixing hole 3, cutting edge is opened the bottom at cutter head, cutter head body bottom surface is trapezoidal, and the cutting edge of the 90 degree angles that trapezoidal bottom surface and cutter head body side form has spring in the fixing hole 3.Because trapezoidal design is adopted in the bottom surface, it is convenient to make cutting edge polish under with blunt situation.There is spring to play cushioning effect in the fixing hole 3, makes that the cutter head shearing area is more smooth.
Above embodiment only is the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
Claims (4)
1. an edger cutter head comprises the cutter head body, and described cutter head body is provided with fixing hole, and cutting edge is opened the bottom at cutter head, it is characterized in that, described cutting edge is the cutting edge of the formed 90 degree angles in cutter head body side and bottom surface.
2. edger cutter head according to claim 1 is characterized in that, described bottom surface is trapezoidal, the cutting edge of the 90 degree angles that described trapezoidal bottom surface and cutter head body side form.
