Abstract
The utility model discloses a stamping die capable of reducing forming stress, and the stamping die comprises an upper die seat, an upper die base plate, an upper die plate, a fixing plate and a compound punch. The fixing plate, the upper die plate and the upper die base plate are sequentially fixed on the upper die seat from bottom to top. The compound punch is formed by sequential attachment of a first punch, a second punch and a third punch, wherein the upper portion of the compound punch is fixed in the upper die plate, and oil filling ports are arranged between the first punch and the second punch and between the second punch and the third punch. Due to the fact that the oil filling ports are arranged between the first punch and the second punch and between the second punch and the third punch, lubrication oil can automatically flow into a position between the punches and a cold stamping sheet material through the oil filling ports, manual oil coating procedures are reduced, labor intensity is thereby reduced, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of diel, particularly relates to the diel of a kind of minimizing moulding stress.
Background technology
Diel is the requisite technological equipment of punching production, is technology-intensive product.Diel mainly is made of upper die and lower die, drift, die etc., the molding mode of stamping parts is mainly finished with cooperating of die by drift, for the ease of the stamping parts moulding, reduce burr, the frictional force when reducing moulding increases the mold use life-span, can oiling on cold stamping sheet material before the punching press, oiling mode commonly used mostly adopts manual operations, and labour intensity is large, and production efficiency is low.
The utility model content
The minimizing moulding stress diel that provides a kind of production efficiency high is provided the purpose of this utility model.
For achieving the above object, technical solution of the present utility model is:
The utility model is the diel of a kind of minimizing moulding stress, and it comprises upper bolster, upper die plate, cope match-plate pattern, fixed head, compound punch; Described fixed head, cope match-plate pattern, upper die plate are fixed on the upper bolster from bottom to top successively; Described compound punch is fitted successively by the first drift, the second drift, the 3rd drift and is consisted of, and the top of compound punch is fixed in the cope match-plate pattern, between the first drift and the second drift, be respectively equipped with pouring orifice between the second drift and the 3rd drift.
The pipeline that communicates with pouring orifice passes respectively the first drift and the 3rd drift, upper die plate, passes upper bolster after joining in upper bolster.
After adopting such scheme, because be provided with pouring orifice between the utility model the first drift, the second drift, the 3rd drift, lubricating oil can flow between drift and the cold stamping sheet material automatically by pouring orifice, has saved artificial inunction process, thereby reduced labour intensity, improved production efficiency.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is the diel of a kind of minimizing moulding stress, and it comprises upper bolster 1, upper die plate 2, cope match-plate pattern 3, fixed head 4, compound punch 5.
Described fixed head 4, cope match-plate pattern 3, upper die plate 2 are fixed on the upper bolster 1 from bottom to top successively.
Described compound punch 5 is fitted successively by the first drift 51, the second drift 52, the 3rd drift 53 and is consisted of, the top of compound punch 5 is fixed in the cope match-plate pattern 3, between the first drift 51 and the second drift 52, be respectively equipped with pouring orifice 6 between the second drift 52 and the 3rd drift 53, this pouring orifice 6 links to each other with oiling machine by pipeline 61.The described pipeline 61 that communicates with pouring orifice 6 passes respectively the first drift 51 and the 3rd drift 53, upper die plate 2, passes upper bolster 1 after upper bolster 1 interior junction.
Emphasis of the present utility model just is: set up pouring orifice at drift.
The above, it only is the utility model preferred embodiment, therefore can not limit the scope that the utility model is implemented with this, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
Claims (2)
1. one kind is reduced the moulding stress diel, and it is characterized in that: it comprises upper bolster, upper die plate, cope match-plate pattern, fixed head, compound punch; Described fixed head, cope match-plate pattern, upper die plate are fixed on the upper bolster from bottom to top successively; Described compound punch is fitted successively by the first drift, the second drift, the 3rd drift and is consisted of, and the top of compound punch is fixed in the cope match-plate pattern, between the first drift and the second drift, be respectively equipped with pouring orifice between the second drift and the 3rd drift.
