Abstract
The invention discloses a punch die. The punch die comprises an upper die (1) and a lower die (2) which are arranged correspondingly. The upper die (1) sequentially comprises an upper die base (3), an upper backing plate (4) and a stripper plate (7). The lower die sequentially comprises a lower die plate (8), a lower backing plate (9) and a lower die base (10), and a material groove (12) is formed in the surface of the lower die plate (8). The punch die is characterized in that a vacuum material sucking opening (14) is formed along the sidewall of the material groove (12) and connected with a vacuum pump through a pipeline. According to the punch die, chippings generated in the punch process can be cleaned away in time.
Description
Technical field
The present invention relates to a kind of mould, particularly relate to a kind of die cutting die.
Background technology
At present, die cutting die is generally made up of a punch and a die, multiple punch and multiple die also can be had to form, but can only complete a kind of blank operation in punch press one stroke.When External Shape is more complicated, just need to be made up of many secondary above single engineering die cutting dies, just can get a qualified product.This mould not only stability is not enough, and waste of manpower cost and machine cost.
Chinese patent Authorization Notice No. is CN203900258U, authorized announcement date is that the utility model patent on October 29th, 2014 discloses a kind of connection gasket cover continuous mould, comprise upper bolster, die shoe, and be arranged at upper bolster, the first punching die between die shoe, second punching die, three groups of cupping tools, punching die and rush salient point mould, described each group of mould comprises the patrix being connected to upper bolster and the counterdie being connected to die shoe respectively, patrix is corresponding with counterdie, patrix along with upper bolster to die shoe motion coordinate counterdie on die shoe respectively the material strip of paired pulses formula walking between each group of mould carry out operation.Although this utility model can with the connection gasket of speed of production production faster cover, can effectively reduce human cost and machine cost as seen, reduce the percent defective of product, visible have higher stability, but find in Long-Time Service, the tiny chip that this mould produces when die-cut cannot be got rid of usually timely, not only can reduce the precision of mould when chip overstocks more, also can accelerate the wearing and tearing of mould.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of die cutting die can getting rid of chip in time.
For solving the problem, the invention provides a kind of die cutting die, comprising the corresponding upper die and lower die arranged; Described patrix comprises upper bolster, upper padding plate and stripper plate successively; Described counterdie comprises lower bolster, lower bolster and die shoe successively, and the surface of described lower bolster is provided with hopper, and the sidewall along described hopper offers vacuum intake mouth, and described vacuum intake mouth is connected with vavuum pump by pipeline.
Also train wheel bridge is provided with between described upper padding plate and described stripper plate.
Stop plate is also provided with between described train wheel bridge and described stripper plate.
Run through in described upper padding plate and described train wheel bridge and be provided with flexible member, the top of described flexible member and the bottom connection of described upper bolster touch, and the other end of described flexible member contacts with the top of described stop plate.
Described flexible member is helical spring.
The bottom even interval of described die shoe be provided with three bottom seat pads.
Compared with prior art, beneficial effect of the present invention is: because die cutting die of the present invention offers vacuum intake mouth along hopper along the sidewall of described hopper, this vacuum intake mouth is connected with vavuum pump by pipeline, in using, after producing chip in hopper, chip is siphoned away by vacuum intake mouth by vavuum pump work timely, and the precision that causes because talus accumulation causes material strip to be in exact position so just can be avoided bad, can reduce the wearing and tearing of punching pin simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: patrix 1, counterdie 2, upper bolster 3, upper padding plate 4, train wheel bridge 5, stop plate 6, stripper plate 7, lower bolster 8, lower bolster 9, die shoe 10, hopper 12, vacuum intake mouth 14, flexible member 16, bottom seat pad 18.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with drawings and embodiments, the present invention is described in further details.At this, exemplary embodiment of the present invention and illustrating for explaining the present invention, but not as a limitation of the invention.
Shown in Figure 1, a kind of die cutting die of the present invention, comprises patrix 1 and the counterdie 2 of corresponding setting, wherein patrix 1 comprises upper bolster 3, upper padding plate 4, train wheel bridge 5, stop plate 6 and stripper plate 7 successively, counterdie 2 comprises lower bolster 8 successively, lower bolster 9 and die shoe 10, the bottom even interval of this die shoe 10 be provided with three bottom seat pads 18, the surface of lower bolster 8 is provided with the hopper 12 that feed strip is passed, special feature of the present invention is: the sidewall along hopper 12 offers vacuum intake mouth 14, this vacuum intake mouth 14 is connected with vavuum pump (not shown) by pipeline, based on this structural design, after producing chip in hopper 12, chip is siphoned away by vacuum intake mouth 14 by vavuum pump work, the precision that causes because talus accumulation causes material strip to be in exact position so just can be avoided bad, the wearing and tearing of punching pin can be reduced simultaneously.
In actual use, run through in upper padding plate 4 and train wheel bridge 5 and be provided with preferably helical spring flexible member 16, the top of this flexible member 16 and the bottom connection of upper bolster 3 touch, the other end of flexible member 16 contacts with the top of stop plate 6, the effect of flexible member 16 drives stripper plate 7 to move straight down timely when die cutting die is opened by stop plate 6, thus play the effect of de-material.
