Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation.
As shown in Fig. 8 to Figure 16, this is used for the mould structure of U-shaped part punching press, including cavity plate 1 and punch-pin 4, cavity plate 1 are located at
Upper mold is divided into two parts, cavity plate 1 and upper binder block 9 in U-shaped opening side, the lower die of binder block in correspondence by the top of punch-pin 4
No blank holder only has punch-pin, i.e., the U-shaped part open end of punch-pin is corresponded on cavity plate equipped with movable upper binder block, punch-pin 4 is far from U-shaped part
Open end side is equipped with movable lower die blank holder 2.
Instantly molding flange 2 jacks up, and after blank is put on lower die blank holder, cavity plate 1 and upper binder block are with lathe sliding block 16
Downlink cavity plate contact blank and compresses blank with lower die blank holder therewith, blank be stretched after a trip upper binder block with it is convex
It is molded tight blank, to reach the flowing for controlling U-shaped part open side blank.This new process distinguishes traditional technique side of getting out of a predicament or an embarrassing situation
Case is effectively reduced waste material after molding.
Punch-pin 4 is located on lower die holder 3, and lower die holder is equipped with the mandril 11 of support driving lower die blank holder, and mandril 11 passes through
Link block 12 is connected with 2 lower part of lower die blank holder, and guide plate II 10 is equipped between lower die blank holder and punch-pin side, guarantees lower molding
Flange is reliable and stable when moving up and down.
Cavity plate 1 is equipped with groove, and the top movable of upper binder block 9 sets in a groove, the top of cavity plate and upper binder block it
Between be equipped with elastic element；Preferably, elastic element is nitrogen gas spring 7.It is equipped between the side of upper binder block and the cell wall of groove
Guide plate I 5, is oriented to by about I 5 guide plate, and guide plate I is mounted on binder block side.
The slot bottom of groove is equipped with the limited block 8 for limiting to upper binder block, and limited block 8 is elastic cushion block, is mounted on recessed
The bottom of slot.Nitrogen gas spring 7 is mounted on cavity plate, and the mandril of nitrogen gas spring is contacted with the transition block 6 being mounted on upper binder block,
Nitrogen gas spring is released stress to be transmitted on upper binder block by transition block, and upper binder block and punch-pin cooperation compress blank, and blank is drawn
It is transformed into required product after prolonging.
The top of upper binder block 9 is equipped with work caging bolt 14, and the bar portion that cavity plate is equipped with work caging bolt passes through
Through-hole.The top of upper binder block is equipped with safe spacing bolt 13, and cavity plate is equipped with the hole that the bar portion of safe spacing bolt passes through,
The length of safe spacing bolt 13 is greater than the length of work caging bolt 14.The upper binder block of control is played with respect to slide fit above and below upper mold
Stroke.
The nut of the work caging bolt 14 of binder block is contacted with cavity plate on upper dead center position, plays position-limiting action, safety
There is a distance between the nut and cavity plate of caging bolt, plays the role of safeguard protection.
Lathe sliding block 16 drives cavity plate downlink, cavity plate and lower die blank holder closure, pushes down blank 15.Since lathe sliding block mentions
The pressure of supply cavity plate is supplied to the pressure of lower die blank holder much larger than mandril, guarantees that cavity plate drives blank holder to continue traveling downwardly, under
Molding flange and cavity plate push down blank, form a distance.
Binder block contacts blank and is closed with punch-pin in upper mold, and molding effect is good.Under lathe sliding block drives cavity plate to continue
It goes, bottom plate open side after U-shaped part, upper binder block compresses blank, and blank material flowing is controlled in drawing process；Nitrogen gas spring quilt
Compression, upper binder block are closed completely with cavity plate, and upper binder block is contacted with limited block, and lower die blank holder, which is molded into bottom drawing, to be terminated.
When because of mold storing, mold has been removed from workbench, and no mandril jacks up blank holder, and blank holder has been fallen, and on
Binder block arrangement is ejected by nitrogen gas spring effect, and upper binder block is arranged only at the side of cavity plate, and upper binder block is ejected, deposits
In upper mold because of upper binder block one-side contact lower die punch-pin, mold unilateral side stress.To solve this problem, four corners of lower die are arranged in
The nitrogen gas spring of arrangement jacks up, and balances upper mold stress.
As shown in Figures 6 and 7, using bottom plate after the molding U-shaped automobile of the mould structure, reduce scrap area, improve material
Expect utilization rate.Floor open side is supplemented without technique afterwards, using the flowing of upper binder control blank, drawing after finally having been formed at this
Part.The blank dimension needed is 1530mm*930mm*0.7mm (material is thick), and the net weight of part is 6.9030Kg, it follows that the part
Stock utilization is 88.29%, relatively tradition get out of a predicament or an embarrassing situation process program promoted material use 5.76%=(88.29%-
82.53%), single vehicle cost is 37.26 yuan, and single-piece saves 1.64 yuan.A situation of selling well vehicle of justing think produces 500000, or the more money per year
Vehicle, the social value of generation are very large.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, if use the improvement for the various unsubstantialities that conception and technical scheme of the invention carry out, or it is not improved will
Conception and technical scheme of the invention directly apply to other occasions, within the scope of the present invention.
