Abstract
The utility model discloses a connecting piece punching die which comprises an upper die base, a lower die base, a concave die and a convex die, wherein the convex die is connected at the lower side of the upper die base, and the concave die is connected at the upper side of the lower die base; a stripper plate is arranged under the upper die base; a rubber block is arranged between the stripper plate and the upper die base; a stripper bolt sequentially passes through the upper die base and the rubber block; a screw cap of the stripper bolt is arranged in the upper die base; the lower end of the stripper bolt is firmly fixed on the stripper plate; the lower end of the convex die passes through the stripper plate and extends outside from the lower side of the stripper plate; a groove is formed at the upper side of the concave die; the bottom surface of the groove is an inclined plane; the concave die has a concave die hole on the bottom surface; the lower side of the stripper plate is an inclined plane jointed with the bottom surface of the grove. The connecting piece punching die is stable in location, does not need a maintenance positioning element, and is high in product quality, simple in structure and low in production cost.
Description
Technical field
The utility model relates to stamping technology field, relates in particular to a kind of brace blanking die.
Background technology
As shown in Figure 3, be part common in a kind of toy, brace is rectangular, one end of brace is connected with part, remainder is separated with part, and the right side structure of brace and part is in an acute angle, and this part adopts blanking die that brace is pressed out from plate upper punch conventionally.It is unstable that the blanking die of prior art easily produces location in process of production, affects product quality, needs often maintenance setting element, and production cost is high.
Utility model content
Problem to be solved in the utility model is, the above-mentioned defect for prior art, provides a kind of positioning stablity, does not need to keep in repair setting element, and product quality is high, simple in structure, the brace blanking die that production cost is low.
The purpose of this utility model is achieved through the following technical solutions.Brace blanking die, comprise upper bolster, die shoe, die and punch, punch is connected to the downside of upper bolster, die is connected to the upper side of die shoe, the below of described upper bolster is provided with stripper, between stripper and upper bolster, be provided with block rubber, unloading bolt is successively through upper bolster, block rubber, the head of a nail of unloading bolt is positioned at upper bolster, the lower end of unloading bolt is fastened on stripper, stretch out from its downside through stripper the lower end of punch, the upper side of described die is provided with groove, the bottom surface of groove is inclined-plane, the die hole of die is located at bottom surface, the downside of described stripper is the inclined-plane fitting with groove floor.The blank of product is put into groove, and the descending stripper of patrix is pushed down blank, and patrix continues descending, the die-cut blank of punch, brace is gone out, and patrix is up, and stripper is pushed down product, and punch is extracted from product, patrix continues up, and stripper leaves product, takes out product, die-cut completing.The blanking die of prior art is aborning because product and mould all can be subject to the thrust of a horizontal direction, so product location is unstable, and the both sides of the utility model groove play the role of positioning, make setting element and die integrated, setting element is position stability in use, and product location is also stable, can not affect the quality of product, therefore there is not the problem of the setting element that needs repairing yet, reduced product cost.
As preferably, the lower end of described punch is oblique bladed.
As preferably, described die shoe is provided with through hole, and through hole is through to downside from the upper side of die shoe, through hole be positioned at die hole under.
The beneficial effects of the utility model are, positioning stablity, does not need to keep in repair setting element, and product quality is high, simple in structure, and production cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of die.
Fig. 3 is the structural representation of product.
The specific embodiment
Below the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
Embodiment, is the structural representation of product as shown in Figure 3, and basic configuration is rectangular, downside has a connecting piece, and brace is also rectangular, and brace is gone out from product, so there is the through hole of a rectangle centre of product, the right side angle of brace and product is 75 °.As shown in Figure 1 to Figure 2, it is brace blanking die, comprise upper bolster 5, die shoe 10, die 1 and punch 6, punch is fixedly connected on the downside of upper bolster by screw, die is connected to the upper side of die shoe by four screws 9 and two alignment pins 8, the below of upper bolster is provided with stripper 7, between stripper and upper bolster, be provided with four block rubbers 3, upper bolster, block rubber is provided with through hole, four unloading bolts 4 are successively through upper bolster, through hole on block rubber, the big up and small down step of through hole in upper bolster, the head of a nail of unloading bolt is positioned at the through hole that upper bolster is large, the lower end of unloading bolt is fastened on stripper, unloading bolt and upper bolster and block rubber matched in clearance, stretch out from its downside through stripper the lower end of punch, the upper side of die is provided with groove 11, groove basic configuration takes the shape of the letter U, groove starts to extend to rear side from the leading flank of die, the distance of extending equals the front and back length of product, groove rear side is the equal of the positioning baffle of product, the left and right width of groove equals the left and right width of product, the bottom surface of groove is inclined-plane, the right side of bottom surface is downward-sloping, the angle tilting is 15 °, the die hole 12 of die is located at bottom surface, the downside of stripper is the inclined-plane fitting with groove floor.The lower end of punch is oblique bladed, and tiltedly sword rolls to left down from upper right side tiltedly, and tiltedly sword is horizontal by 30 °, and tiltedly the upper right side of sword and the smooth circular arc in the right side of punch are connected.Die shoe is provided with through hole, and through hole is through to downside from the upper side of die shoe, through hole be positioned at die hole under.The blank of product 2 is put into groove, and the left and right sides of groove and rear side are by the blank location of product, and patrix is descending, stripper is pushed down blank, and patrix continues descending, the die-cut blank of punch, brace is gone out, patrix is up, and stripper is pushed down product, and punch is extracted from product, patrix continues up, stripper leaves product, takes out product, die-cut completing.Both sides and the rear side of groove play the role of positioning, and make setting element and die integrated, and setting element is position stability in use, can not affect the quality of product, therefore also do not have the problem of the setting element that needs repairing, and have reduced product cost.
The above is the preferably specific embodiment of the utility model, not with this, limits practical range of the present utility model.The utility model can also have other embodiment, only otherwise deviate from spirit of the present utility model, and within no matter in form what kind of conversion all drops on protection domain of the present utility model.
