Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
As shown in fig. 1 and 2, the present invention provides an upward-punching and downward-waste-discharging punching die which comprises an upper die holder 1 and a lower die holder 12 (divided up and down in the vertical direction shown in fig. 1).
The lower die holder 12 is sequentially and fixedly provided with a lower backing plate 11 and a lower fixing plate 10 through countersunk head screws. A lower mounting hole (not shown) is formed in the lower fixing plate 10, and a punch holder 20 is disposed in the lower mounting hole. A screw 24 penetrating through the lower shim plate 11 is screwed into the end face below the punch holder 20 to fixedly set the punch holder 20 to the lower shim plate 11. A stripper 7 is sleeved on the punch fixing seat 20, and the stripper 7 is connected with the lower die seat 12 through a discharge mandril 8 and a nitrogen spring 21 which are arranged on the lower die seat 12. The discharging ejector rod 8 is movably arranged on the lower die holder 12 through a bearing sleeve 9.
An upper backing plate 2 is fixedly arranged on the upper die base 1 through a countersunk head screw 25, and an upper fixing plate 3 is fixedly arranged on the upper backing plate 2 through a countersunk head screw. A die backing plate 4 is fixedly arranged on the upper fixing plate 3, a die plate 5 is fixedly arranged on the die backing plate 4, and die mounting holes (not shown) for accommodating the punching dies 14 are formed in the die backing plate 4 and the die plate 5. The punch die 14 has a central aperture 26. Punch retainer 20 is provided with a punch 16 that extends through central bore 26.
The edge of the punching female die 14 is provided with a guide seat 18 and a pressing block 6 for fixing the guide seat 18, and the pressing block 6 is fixedly arranged on the female die plate 5. The guide seat 18 fixes the punching die 14. A second spring ejector rod 17 penetrating through a guide seat 18 is arranged in the punching concave die 14.
With the above structure, a structure of punching upward has been realized. And the discharging ejector rod 8 and the nitrogen spring 21 drive the discharging plate 7 to eject the product upwards to realize the discharging action. The second spring ejector rod 17 is matched with a downward ejection product 19 to assist in discharging.
Further, an upper mounting hole (not shown) is formed at the bottom of the center hole 26 in the upper fixing plate 3, and a drawing punch 13 is screwed to the upper mat 2 by a screw 27 to fixedly mount the drawing punch 13 to the upper mat 2. The lower die holder 12 is provided with a waste discharge hole 28 therethrough, and the punch holder 20 and the punch 16 are provided with through holes 29 communicating with the waste discharge hole 28. The product is driven upwards by the punching punch 16, and is cut off along the inner side edge of the concave template 5, so that the punching operation is realized. The punch 16 carries the punched scrap 15 (shown in the figure, where no plate-shaped scrap is actually present) to continue moving upward until it passes over the drawing punch 13, so that the scrap 15 is drawn by the drawing punch 13 and forms a cup-shaped scrap 23 downward, so that it can be discharged downward along the through-hole 29 and the waste discharge hole 28.
Further, a mounting hole 30 is formed in the lower end face of the drawing male die 13, and a first spring top rod 22 extending out of the drawing male die 13 is arranged in the mounting hole 30. The first spring ejector 22 pushes the cup-shaped waste 23 downward, assisting the waste to separate from the drawing punch 13.
Further, an inwardly projecting collar 31 is provided on the inner side wall of the punch 16. The retainer ring 31 is used for preventing the cup-shaped waste 23 from wrapping the stretching male die 13 and rising along with the cup-shaped waste when the stretching male die 13 returns upwards.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
