And, between described cope match-plate pattern 1 and lower bolster 18, be also provided with for the mesopore of square shaped washer draw light hole operation draw light in casement, described cope match-plate pattern 1 lower end of drawing casement in light to comprise to be located at described the first stripper plate 10 1 sides draw light mesopore punch 29, and be located on the first concave template 13 and with draw light mesopore punch 29 corresponding draw light mesopore die 28.
As shown in Figure 5, in the utility model, the angle of the inclination angle X that described pressure angle punch 25 is provided with is 1.5 °, presses the inside, inclination angle of angle punch 25 to be also provided with the fillet R1 consistent with the radius of mesopore to be pressed two sides pressure angle R.Be convenient to so on the one hand the processing of mesopore to be pressed two sides pressure angle R, be convenient on the other hand discharging, blank can conveniently be unloaded, then turn to another side and press pressure angle, mesopore two sides.And the quantity of the square washer product that continuous mould punching press of the present utility model once generates is three.
In order to realize continuous processing, also be provided with material guide device in the 3rd concave template 15 1 sides, described material guide device comprises guide post 19, stock guide 20 and stock guide backing plate 21 and ball outer guiding post 22, described stock guide 20 is installed on stock guide backing plate 21, and described guide post 19 and ball outer guiding post 22 are installed on respectively on stock guide 20.This is because the thickness of washer plate is 3.0mm, belong to thicker material, timber intensity is large, adopt common fixing guide mode to be difficult to washer plate to send into mould mouth, and can not meet instructions for use, therefore adopt the guide mode of rotating guide post more suitable, effectively prevent the phenomenon that gets stuck, reduce the wear extent of stock guide.
When final cutting products of separated after machining, convenient in order to go out part, need on the first concave template 13, be provided with the blowning installation for separating of workpiece, the form that blowning installation can blow afloat for cylinder.
Because mould volume is larger, single amount is also large, and it is inconvenient that a whole set of mould is pulled down maintenance, for larger blanking punch, all adopts screw fixed, conveniently pulls down maintenance.And it is all mold inserts that above-mentioned die is set, and is directly installed on concave template, in the time of maintenance, can directly take off, because sheet material is thicker, die wear amount is large simultaneously, and inlaid piece of mould has all adopted SKD11 processing, hot place amount: HRC60-62 °.And punch die 27 is because need with material strip synchronization action, so punch die part has been made to the structure of floating cavity die, die is fixed on the second stripper plate.Meanwhile, because punch punch 26 and punch die 27 are because often changing part, sharpening, so also adopted mold insert to enter piece form, easy disassembly and maintenance.And in order can material strip to be unloaded and to lift, all install the powerful device for discharging of secondary additional at each punch die 26 and punch punch 27 fixed heads in the time that this step punching press completes, be provided with secondary lastics thimble.
Because the stripper plate of mould in the utility model has played the effect of guiding, discharging, binder, because mould is longer, stripper plate is divided into three sections, be mainly in order to facilitate processing, installation and debugging and maintenance.Also can reduce the imbalance problem of the long generation of stripper plate simultaneously.And on the stripper plate of each section, be equipped with four inner guiding posts, play the accurate guide effect of stripper plate, strengthened the anti-inclined to one side ability of stripper plate; Rush in mesopore operation in essence simultaneously, the guiding that the stripper plate of this section rushes punch to essence seems and is even more important, can make bilateral gap value be not more than 0.01, as excesssive gap, punch guiding is insuperior, essence is rushed mesopore and is produced tomography, can cause mesopore cannot pull out suitable fineness, so there is higher processing request in this workshop section for stripper plate, stripping force is larger herein simultaneously, need calculate stripping force and suitable spring is installed, to facilitate unloading.
Adopting after mould structure of the present utility model, technique is highly stable, and production efficiency obtains greatly higher, and mold repair is convenient.And on washer product HSS040040001220S, promote design application, production production capacity reaches 36000PCS/8 hour/people, and one-shot production production capacity is 8000PCS/8 hour/3 people, and production efficiency has improved 13.5 times.Obtain good economic benefit, greatly reduced workman's working strength simultaneously, improved the security of producing, solved the problem of production bottleneck.
Although described by reference to the accompanying drawings embodiment of the present utility model; but the patent owner can make various distortion or modification within the scope of the appended claims; as long as be no more than the described protection domain of claim of the present utility model, all should be within protection domain of the present utility model.
