Abstract

The utility model discloses a shutter die which comprises a convex die and a concave die. A forming die is arranged on the concave die, and at least one tool is arranged on the convex die. The tool is used for punching plate materials. A cutting edge is arranged on the tool, and height difference exists between a first end portion and a second end portion of the cutting edge. The shutter die can achieve point-by-point punching to the plate materials in a short period in microscopic view, and reduces blanking force, noise and vibration.

Description

Louvering die

Technical field

The utility model relates to mould applications, particularly relates to a kind of louvering die.

Background technology

At present, the machine-shaping of the shutter on the market need be adopted two procedures, and for example the shutter on the process window air conditioner device shell is blurted out first, side flanging is finished the production to shutter again, die-cut mode is that line is die-cut, and cutter for same uses when producing that this kind mode blanking pressure is large, noise large, vibrations are large as shown in Figure 1 to Figure 3, it is the produce difficult point of metal plate punching, as one 40 be the shutter of unit, just need about 150 tons blanking pressure, noise is more than 110 decibels; And a window machine outer cover part, the shutter that 14 unit are arranged at most so adds up to nearly 2100 tons of blanking pressures, therefore, the equipment that relates to is a lot of and the 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, and be unrenewable in shutter production, so the predatoriness of punch press is used, huge on the impact that punch press causes, cause processing cost high, working (machining) efficiency is low.

The utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a kind of louvering die simple in structure, reasonable in design, and it has reduced blanking pressure, noise and vibrations, and the utility model realizes that the technical scheme that above-mentioned purpose adopts 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 used 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 a plurality of, and a plurality of described cutters are spaced, and first end and the second end of the blade of two adjacent described cutters are interspersed.

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

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

The beneficial effects of the utility model are: louvering die of the present utility model has reduced blanking pressure, noise and vibrations.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples louvering die of the present utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

With reference to Fig. 4 to Figure 10, louvering die one embodiment of the present utility model comprises punch 2 and die 3, punch 2 is packed on the upper bolster (not shown), described upper bolster connects the slide block of punch press, move up and down with described slide block, die 3 is packed on the 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 used for blanking plate 5, and described cutter 1 can be changed, and 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, h1＜h2 or h1＞h2 at the height of its second end.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 a plurality of, a plurality of described cutters 1 are spaced, first end and the second end of the blade 11 of two adjacent described cutters 1 are interspersed, namely the h1 of a blade 11 highly holds the h2 with another blade 11 highly to hold adjacent, adopt the formula that the interleaves layout of blade 11, interleave punching press about cutter 1 and offset plate 5 original side blow power, the louvering die of present embodiment is finished a punching press at stamping machine, can process shutter, and then realize that automated production provides sufficient preparation for shutter processing.

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

This louvering die is by oblique sword (first end and the second end of blade have height fall) cutter punching press, realize die-cut to the pointwise of plate in short time from microcosmic, 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 simultaneously the formula that the interleaves layout of a plurality of cutters, interleave punching press about cutter and offset the original side blow power of plate, thereby realize reducing the purpose of blanking pressure and side blow power, contrast by the shutter processing to the window-mounted air conditioner device, use louvering die of the present utility model front and back and contrast such as following table:

As can be seen from the table, use the louvering die of present embodiment, reduced by 2/3 blanking pressure, noise and vibrations all obviously improve, and the outward appearance of the shutter that processes 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 the 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 utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
