Abstract
The invention discloses a punching die with a preheating function. The punching die comprises an upper die (1) and a lower die (2) corresponding to the upper die (1). The upper die (1) sequentially comprises an upper die seat (3), an upper cushion plate (4) and a stripper plate (7). The lower die sequentially comprises a lower die plate (8), a lower cushion plate (9) and a lower die seat (10). The punching die with the preheating function is characterized in that a heating block (11) is arranged at the feeding end of the lower die plate (8), the heating block (11) is provided with a hole (12) for a material belt to penetrate through, a plurality of heating rods (13) are evenly arranged in the heating block (11) at intervals, and the outer surface of the heating block (11) is provided with a heat insulating layer. According to the punching die with the preheating function, the defective rate can be reduced when a complex structure is machined.
Description
Technical field
The present invention relates to a kind of die cutting die, particularly relate to a kind of die cutting die with preheat function.
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, this mould does not have preheat function before die-cut, like this when some special constructions of punching press, will be bad because of the ductility of material strip, the defect causing defect rate higher and problem.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of have preheat function die cutting die.
For solving the problem, the invention provides a kind of die cutting die with preheat function, 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, the feed end of described lower bolster is provided with heat block, described heat block is provided with the hole that feed strip is passed, evenly spacedly in described heat block is provided with multiple heating rod, the outer surface of described heat block has thermal insulation layer.
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 has heat block, during use, when material strip passing hole is through heat block, under the effect of heating rod, heat block is generated heat, thus heat is passed to material strip, after making material strip preheating, there is good ductility, thus be convenient to process more complicated structure, reduction in the numbers of seconds.
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, heat block 11, hole 12, heating rod 13, 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 with preheat function 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, special feature of the present invention is: the feed end of lower bolster 8 is provided with heat block 11, this heat block 11 is provided with the hole 12 that feed strip is passed, evenly spacedly in heat block 11 be provided with multiple heating rod 13, the outer surface of heat block 11 has thermal insulation layer (not shown), the existence of thermal insulation layer can prevent operator to be burned, based on this structural design, when material strip passing hole 12 is through heat block 11, under the effect of heating rod 13, make heat block 11 generate heat, thus heat is passed to material strip, after making material strip preheating, there is good ductility, thus be convenient to process more complicated structure, reduction in the numbers of seconds.
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.
