The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Consult shown in Fig. 1, Fig. 2, the mould material guide structure of a kind of square washer that the utility model provides, comprise the stock guide 3 that is installed on mould feeding mouth one end, the many groups of rotating outer guide posts 4 that are oppositely arranged are also installed on described stock guide 3, rotating guide column sleeve 5 is also installed on the circumferencial direction of every group of described outer guide post 4.
Concrete, the structure of above-mentioned outer guide post 4 is T shape structure, it comprises outer guide column end 10 and the outer guide necking portion 11 of integral type, in described outer guide column end 10, be also provided with outer guide post head 12, described guide column sleeve 5 is located at outer guide necking portion 11, its two ends respectively with the inner side of outer guide column end 10 and the Surface Contact of stock guide 3, like this, washer plate owing to being subject to the rotary action of guide column sleeve 5 and outer guide post 4, can reach very easily mould feeding mouth in the time of pan feeding.Above-mentioned stock guide 3 is specifically installed on the counterdie 1 of mould feeding mouth one end by a stock guide backing plate 2, is very beneficial for the saving in space.
Concrete, one group of rotating interior guide post 9 is also installed on above-mentioned stock guide 3, this interior guide post 9 is located at outer guide post 4 inner sides of described mould feeding mouth side, and the setting of interior guide post 9 is more convenient for the importing of washer plate.
Can also be provided with the slab feeder 8 corresponding with stock guide 3 in a side of described stock guide 3, realize the automatic feeding of washer plate in whole Mould Machining process.
Generally after pan feeding, can carry out punch process to washer plate by mould, owing to being subject to the impact of square washer structure, washer plate step is divided into following some: blank (being washer plate) is cut to the step of step pitch, is produced coarse positioning and eliminate the inconsistent of itemize coiled strip width; Blank is carried out to pre-punching for accurately locating the step of the bullport of material strip; The step that blank is carried out essence and rushes mesopore; Blank is carried out to the step at mesopore precompressed angle; Blank is pressed to the step at pressure angle, mesopore two sides; Blank is carried out to the step of punch; Blank is drawn to the step of light mesopore; Blank is carried out to the step of trimming, generate square washer product; The step that square shaped washer product separates, wherein key is pressure angle, mesopore two sides, and mesopore draws the operation of light and plane punch, so, in the time that mould structure is introduced, article draw the structure of light and plane punch for pressure angle, mesopore two sides, mesopore.
Consult shown in Fig. 3, material guide structure of the present utility model is arranged on mould, the structure of this mould comprises cope match-plate pattern 31 and lower bolster 1, described cope match-plate pattern 31 is provided with upper padding plate from top to bottom successively, fixed head, de-backboard and stripper plate, on lower bolster 1, be provided with successively lower bolster and concave template, cope match-plate pattern 31 by guide pillar successively with upper padding plate, fixed head, de-backboard is connected with stripper plate, between fixed head and de-backboard, be provided with gap, between cope match-plate pattern 31 and lower bolster 1, be also provided with successively the mesopore stamping die that carries out punching press for the mesopore of square shaped washer, the pressure angle stamping die that carries out punching press for the pressure angle, mesopore two sides of square shaped washer, and the punch mould that carries out punching press for the punch of square shaped washer, wherein, mesopore stamping die comprises that the essence of being located at cope match-plate pattern 31 lower ends rushes mesopore punch 23, and is located at and on concave template, rushes with essence the essence that mesopore punch 23 is corresponding and rush mesopore die 24, pressing angle stamping die is the pressure angle punch 25 of being located on concave template, presses angle punch 25 to be provided with inclination angle (generally selecting 1.5 °), punch mould comprises the punch die 27 of being located at stripper plate lower end, and is located at punch punch 26 corresponding with punch die 27 on concave template.
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.
And the stripper plate in above-mentioned mould has played the effect of guiding, discharging, binder, because mould is longer, stripper plate has been divided into three sections, is 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.
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.
