Abstract
A safe 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 (2) sequentially comprises a lower die plate (8), a lower backing plate (9) and a lower die base (10). The safe punch die is characterized in that screw rods (11) capable of rotating are horizontally arranged on the two sides of the lower die plate (8) respectively, each screw rod (11) is in transmission connection with a motor (12), each screw rod (11) is sleeved with an L-shaped movable block (13), and each movable block (13) is in threaded fit with the corresponding screw rod (11). The safe punch die has high use safety.
Description
Technical field
The present invention relates to a kind of die cutting die, particularly relate to a kind of safety-type 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, mould due to said structure is not provided with any release mechanism, after die sinking, if patrix falls suddenly because of mechanical breakdown, easily cause potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention is to provide the higher die cutting die of a kind of security.
For solving the problem, the invention provides a kind of safety-type 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, the both sides of lower bolster described in it are horizontally disposed with the screw mandrel that can rotate respectively, described screw mandrel is connected with motor-driven, described screw mandrel is set with L-type movable block, and described movable block coordinates with described wire rod thread.
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 the present invention is when after die sinking, motor drives screw mandrel to rotate, make movable block part translation on lower bolster, even if patrix falls suddenly because of mechanical breakdown like this, because the isolation of movable block still has reliable safety clearance between patrix and counterdie, thus can eliminate safe hidden trouble.
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, screw mandrel 11, motor 12, movable block 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 safety-type 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, special feature of the present invention is: be horizontally disposed with the screw mandrel 11 that can rotate respectively in the both sides of lower bolster 8, this screw mandrel 11 is in transmission connection with motor 12, screw mandrel 11 is set with L-type movable block 13, this movable block 13 and screw mandrel 11 threaded engagement, based on this structural design, in use, when after die sinking, motor 12 drives screw mandrel 11 to rotate, make movable block 13 part translation on lower bolster 8, even if patrix 1 falls suddenly because of mechanical breakdown like this, because the isolation of movable block 13 still has reliable safety clearance between patrix 1 and counterdie 2, thus can eliminate safe hidden trouble.
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.
