Abstract

The invention discloses a shutter die which comprises a male die and a female die. The female die is provided with a forming die, the male die is provided with at least one cutter which is used for punching plates, the cutter is provided with a blade, and height difference exists between the first end and the second end of the blade. According to the shutter die, from the aspect of microscopic view, point-by-point cutting of the plates is achieved in short time, and the punching force, the noise and the vibration are lowered.

Description

Louvering die

Technical field

The present invention relates to mould applications, particularly relate to a kind of louvering die.

Background technology

At present, the machine-shaping of the shutter on market need adopt two procedures, and for example the shutter on process window air conditioner device shell, first blurts out, side flanging completes the production to shutter again, die-cut mode is that line is die-cut, and as shown in Figure 1 to Figure 3, mode blanking pressure is large, noise large, vibrations are large when producing, to use this kind for cutter for same, it is the produce difficult point of metal plate punching, as one 40 shutters that are unit, just need the blanking pressure of 150 tons of left and right, noise is more than 110 decibels; And a window machine outer cover part, there is at most the shutter of 14 unit, so add up to nearly 2100 tons of blanking pressures, therefore, the equipment that relates to is a lot of and punching press number of times is also a lot, simultaneously large blanking pressure and punching press unbalance loading, easily cause the slide block loss of significance of a lot of punch presses, unrenewablely in shutter, produces, so the predatoriness of punch press is used, the impact that punch press is caused is huge, causes processing cost high, and working (machining) efficiency is low.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides a kind of louvering die simple in structure, reasonable in design, it has reduced blanking pressure, noise and vibrations, and the present invention realizes the technical scheme that above-mentioned purpose adopts and is:

A kind of louvering die, comprises punch and die, and described die is provided with finishing die, described punch is provided with at least one cutter, described cutter is for blanking plate, and described cutter is provided with blade, and first end and the second end of described blade have height fall.

More preferably, the height of described blade between its first end and the second end increases continuously.

More preferably, the quantity of described cutter is multiple, and multiple described cutters are spaced, and described in adjacent two, first end and the second end of the blade of cutter are interspersed.

More preferably, the height of described blade between its first end and the second end first reduces to increase afterwards " V " font that is upright, or the height of described blade between its first end and the second end first increases " V " font that reduces to be afterwards handstand.

More preferably, the triangular in shape or arc of the vertical sectional shape of described blade.

The invention has the beneficial effects as follows: louvering die of the present invention has reduced blanking pressure, noise and vibrations.

The specific embodiment

In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, louvering die of the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.

With reference to Fig. 4 to Figure 10, louvering die one embodiment of the present invention comprises punch 2 and die 3, punch 2 is packed on upper bolster (not shown), described upper bolster connects the slide block of punch press, with described slide block, move up and down, die 3 is packed on die shoe (not shown), described die shoe is packed on the workbench of described punch press, described die 3 is provided with finishing die 4, described punch 2 is provided with at least one cutter 1, described cutter 1 is for blanking plate 5, described cutter 1 can be changed, described cutter 1 is provided with blade 11, first end and the second end of described blade 11 have height fall, be that blade 11 is h1 at the height of its first end, blade 11 is h2 at the height of its second end, h1 < h2 or h1 > h2.Preferably, the height of described blade 11 between its first end and the second end increases continuously.

More preferably, as a kind of embodiment, described blade 11 the triangular in shape or arc of vertical sectional shape.

The quantity of described cutter 1 can be multiple, multiple described cutters 1 are spaced, described in adjacent two, first end and the second end of the blade 11 of cutter 1 are interspersed, the h1 of a blade 11 highly holds and highly holds adjacent with the h2 of another blade 11, adopt the formula that the interleaves layout of blade 11, the left and right of cutter 1 interleaves punching press and has offset the original side blow power of plate 5, the louvering die of the present embodiment completes a punching press on stamping machine, can process shutter, and then provide sufficient preparation for shutter processing realizes automated production.

More preferably, as a kind of embodiment, as shown in Figure 11 and Figure 12, the height of blade 11 between its first end and the second end first reduces to increase afterwards " V " word that is upright; Or as shown in Figure 13 and Figure 14, the height of described blade between its first end and the second end first increases " V " font (zigzag) that reduces to be afterwards handstand.

This louvering die is by oblique sword (first end and the second end of blade have height fall) cutter punching press, within the microcosmic short time, realize die-cut to the pointwise of plate, change the die-cut mode of line of flat sword in the past (first end of blade and the second end are without height fall) cutter punching press, greatly reduced the blanking pressure of blanking plate; Adopted the formula that the interleaves layout of multiple cutters simultaneously, the left and right of cutter interleaves punching press and has offset the original side blow power of plate, thereby realize the object that reduces blanking pressure and side blow power, by the shutter processing to window-mounted air conditioner device, contrast, apply louvering die of the present invention front and back and contrast as following table:

As can be seen from the table, the louvering die of application the present embodiment, has reduced by 2/3 blanking pressure, and noise and vibrations all obviously improve, and the outward appearance of the shutter processing is not affected, and its air quantity performance is also basically identical with existing former part.

The reduction of blanking pressure, has reduced the impact on slider of punch precision; One time punching molded, improved production efficiency, for condition has been created in automated production.

The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It 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.
