Abstract
The invention discloses a high-precision continuous punching die. The high-precision continuous punching die comprises an upper die (1) and a lower die (2) which are correspondingly arranged, wherein the upper die (1) comprises an upper die seat (3), an upper cushion board (4) and a discharging plate (7) which are sequentially arranged; the lower die comprises a lower die plate (8), a lower cushion board (9) and a lower die seat (10) which are sequentially arranged. The high-precision continuous punching die is characterized in that a plurality of air channels (12) are uniformly arranged at intervals in the lower die plate (8) in the length direction and connected with an air blower (14) through air pipes (13). According to the high-precision continuous punching die, the lower die plate can be quickly radiated through circulating air, so that the circumference of deformation caused by raised temperature can be avoided, and the die can remain high temperature after continuous punching.
Description
Technical field
The present invention relates to a kind of die cutting die, particularly relate to the continuous cutting mould that a kind of precision is higher.
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, there is higher stability as seen, but, find in Long-Time Service, above-mentioned mould after long-time continuous operation, due to continuous mechanical stamping operation, the temperature of template can change to some extent, after the temperature rising of template, can there is certain extension distortion in it, thus die cutting accuracy can be caused to reduce.
Summary of the invention
Technical problem to be solved by this invention is to provide the higher continuous cutting mould of a kind of die cutting accuracy.
For solving the problem, the invention provides the continuous cutting mould that a kind of precision is higher, 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, is provided with multiple air channel along its uniform length interval in described lower bolster, and described air channel is connected with blower fan by airduct.
The vertical section in described air channel is triangle, and on the inwall in described air channel, be provided with multiple heat transfer sheet.
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 lower bolster of the present invention can be dispelled the heat fast by circulated air, thus avoid Yin Wendu to raise and produce the situation of being out of shape, even if such mould still can keep higher precision after continuous cutting.
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, air channel 12, airduct 13, blower fan 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, the continuous cutting mould that a kind of precision of the present invention is higher, 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, special feature of the present invention is: be provided with multiple air channel 12 along its uniform length interval in lower bolster 8, this air channel 12 is connected with blower fan 14 by airduct 13, and the vertical section in air channel 12 is triangle, on the inwall in each air channel 12, be provided with multiple heat transfer sheet simultaneously, based on this structural design, lower bolster 8 can be dispelled the heat fast by circulated air, thus avoid Yin Wendu to raise and produce the situation of being out of shape, even if such mould still can keep higher precision after continuous cutting.
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.
