Abstract

The utility model discloses a trimming cutter for a trimming die. A material pressing core and an upper trimming cutter are arranged on an upper die base of the trimming die, a lower trimming cutter is arranged on a lower die of the trimming die, and a blade, used for vertically trimming, of the upper trimming cutter is an inclined face forming an included angle with the horizontal plane. According to the trimming cutter for the trimming die, a blade face of the upper trimming cutter is the inclined face, the blade base is in contact with the face of the lower trimming cutter and sheet metal in the trimming process, and therefore impact and abrasion between the cutters can be reduced. On one hand, replacing frequency of the cutter can be reduced, on the other hand, micro-deformation caused by impact on the die in the punching process can be reduced, so that the use effect of the die is improved, and the service life of the die is prolonged.

Description

A kind of knife tool for Trimming Die

Technical field

The utility model relates to the Press Tools for Automobiles field, is specifically related to the knife tool on Trimming Die.

Background technology

In today of manufacturing industry high speed development, the client is also more and more higher to the requirement of product quality.For mould manufacturing enterprise, need to provide the more mould of high-efficiency and economic.Yet, in resource scarcity, under the current conditions that Master Cost and wage for workmen are gone up, need enterprise to improve the technology content of single mold, exploitation and the more efficient mechanism of use, reduce the design and development cost.

For Trimming Die, the situation that usually there will be knife tool serious wear, tipping to scrap, not only affect the mould result of use, also can increase die cost.As shown in Figures 3 and 4, knife tool on Trimming Die commonly used, lower knife tool is arranged on die shoe, and upper knife tool and material pressing core all are arranged on upper bolster, during matched moulds, material pressing core carries out binder, then goes up knife tool and has contacted the waste material excision with lower knife tool.

For the zone of vertical trimming, this kind of knife tool is in the deburring process, and cutting edge roundness and plate be at first to contact, and remains to deburring always and finish, and the tool damage phenomenon is even more serious.

In producing in reality, often by the method that increases tool mechanical intensity, reduce the cutter changing frequency, this mode can be resisted the power of cutting out that cutter is subject to a certain extent; But due to the mutual percussion between cutter, still can in the high-frequency stamping press process of plate, occur that cutter is broken or the problem of tipping, also can increase the suffered impulsive force of mould simultaneously, cause the micro-distortion of mould, affect the result of use of mould.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of percussion effectively reduced between cutter is provided, reduce the cutter changing frequency, reduce that mould is hit in punching course and micro-distortion of producing, thereby improve the knife tool on mould result of use and the Trimming Die in life-span.

To achieve these goals, the technical solution adopted in the utility model is:

Should be for the knife tool of Trimming Die, the Trimming Die upper bolster is provided with material pressing core and upper knife tool, on the counterdie of Trimming Die, sets knife tool, and described upper knife tool is the inclined-plane horizontal by angle for the blade of vertical trimming.

Described upper knife tool is less than 90 degree for inclined-plane and the horizontal plane angle of vertical trimming.

The utility model has the advantage of: should be for the knife tool of Trimming Die, the cutting edge face of upper knife tool vertical trimming is inclined-plane, can guarantee like this in the deburring process with plate and counterdie knife tool between in the mode of face, contact; Along with the carrying out of deburring operation, the cutting edge face of upper knife tool starts all to drop into deburring work, thereby has slowed down the impact wear between cutter; And the counterdie knife tool is not made change; Can guarantee that like this trimming line in vertical trimming technique can not change, the deburring operation effectiveness of mould can not be affected, and mould structure is not change also, and cost is lower; After impact wear between cutter reduces, on the one hand can reduce the cutter changing frequency, can reduce on the other hand that mould is hit in punching course and micro-distortion of producing, thereby improve mould result of use and life-span.

The accompanying drawing explanation

The content of below each width accompanying drawing of the utility model specification being expressed and the mark in figure are briefly described:

Fig. 1 is the structural representation of the utility model for the knife tool of Trimming Die;

Fig. 2 is the use state reference map of Fig. 1 for the knife tool of Trimming Die;

Fig. 3 is for the structural representation of the knife tool of Trimming Die in prior art;

Fig. 4 is the use state reference map of Fig. 3 for the knife tool of Trimming Die;

Mark in above-mentioned figure is:

1, upper knife tool, 2, material pressing core, 3, counterdie, 4, lower knife tool.

The specific embodiment

Below contrast accompanying drawing, by the description to optimum embodiment, the specific embodiment of the present utility model is described in further detail.

As shown in Figure 1, should be for the knife tool of Trimming Die, the Trimming Die upper bolster is provided with material pressing core 2 and upper knife tool 1, on the counterdie 3 of Trimming Die, sets knife tool 4, and upper knife tool 1 is the inclined-plane horizontal by angle for the blade of vertical trimming.

Upper knife tool 1 is for inclined-plane and the visual concrete condition adjustment of horizontal plane angle of vertical trimming, and upper knife tool 1 is less than 90 degree for inclined-plane and the horizontal plane angle of vertical trimming, is preferably 85～87 degree.

As shown in Figure 2, when Trimming Die carries out the deburring operation, material pressing core 2 at first with counterdie 3 closures, complete binder, lower knife tool 4 is arranged on counterdie 3; Along with patrix moves downward, upper knife tool 1 contacts gradually with plate and lower knife tool 4; Upper knife tool 1 cutting edge minimum point contacts with plate at first, and due to cutting edge, with certain angle, along with the carrying out of deburring, the cutting edge face slowly contacts plate and is no longer that the mode of putting is carried out the deburring operation; After the complete closure of mould, upper knife tool 1 and lower knife tool 4 arrive dead point, and the deburring operation completes.

From the above-mentioned course of work, can find out, the deburring operation of Trimming Die from start to end, between the cutting edge of upper knife tool 1 and lower knife tool 4, be that the mode with face contacts, thereby it is stressed to avoid cutter to concentrate, and cutter and mould are stressed comparatively even.Impact wear between cutter reduces, and the cutter changing frequency reduces, and improve the service life of cutter; Simultaneously Trimming Die service life, design and develop into instinct and effectively reduce.

Should be for the knife tool of Trimming Die, do not increase the mould complexity, be applicable to vertical trimming technique by it, not only can reduce impact wear between knife tool, prevent tipping, reduce the frequency of cutter changing in using, can also prevent that larger distortion from appearring in mould, thereby improve die life.

The above is exemplarily described the utility model; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out, all within protection domain of the present utility model.
