Abstract
The utility model relates to a stamping die technical field, in particular to drift structure, including location portion, blade bar portion, transition portion and sword head portion, location portion, blade bar portion, transition portion and sword head portion are fixed connection in proper order from top to bottom, the cross section of location portion is the quincunx, transition portion is used for making blade bar portion and sword head portion fixed connection, the bottom face of sword head portion is the inclined plane, and the angle of inclination of the bottom face of sword head portion is 2. Through setting up the bottom face of drift to the setting of slope, can play when the drift is die-cut downwards with the area of contact of die-cut material increase gradually, die-cut girth increases gradually, the effect that makes holistic die-cut power among the punching press reduce.
Description
Technical Field
The utility model relates to a stamping die technical field, in particular to drift structure.
Background
In recent years, with the development of cold stamping technology, the stamping precision is higher and higher, the quality of stamping products is better and better, the types and materials of punches are changed continuously, and the service life of the punches is prolonged.
At present, chinese patent No. CN203917564U discloses a punch structure, which includes a flange portion, a punch and a cutting edge portion, the flange portion and the cutting edge portion are respectively disposed at two ends of the punch, and the punch structure is characterized in that a boss is disposed at the top end of the flange portion, and the diameter of the boss is slightly smaller than the straightness of the punch.
The above prior art solutions have the following drawbacks: the required blanking force is large, resulting in some dies not matching large presses.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a drift structure to solve the problem that above-mentioned prior art exists.
The above technical purpose of the present invention can be achieved by the following technical solutions:
the utility model provides a punch structure, includes location portion, sword pole portion, transition portion and sword head portion, location portion, sword pole portion, transition portion and sword head portion are fixed connection in proper order from top to bottom, the cross section of location portion is the quincunx, transition portion is used for making sword pole portion and sword head portion fixed connection, the bottom face of sword head portion is the inclined plane, and the angle of inclination of the bottom face of sword head portion is 2.
Through adopting above-mentioned technical scheme, make the die-cut area of drift increase gradually, required punching force when reducing the drift die-cut.
In a further embodiment, the surface of the tool head is provided with a layer of degree Cr of 3um to 5 um.
To sum up, the utility model discloses following beneficial effect has:
1. through setting up the bottom face of drift to the setting of slope, can play when the drift is die-cut downwards with the area of contact of die-cut material increase gradually, die-cut girth increases gradually, the effect that makes holistic die-cut power among the punching press reduce.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
In the figure, 1, a positioning part; 2. a blade bar part; 3. a transition section; 4. a knife head part.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
In which like parts are designated by like reference numerals. It should be noted that the terms "front", "back", "left", "right", "upper" and "lower" used in the following description refer to directions in fig. 1, the terms "bottom" and "top", "inner" and "outer" refer to directions toward and away from a particular component geometry, respectively, and the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present specification, "plurality" means two or more unless the direction of the center is specifically defined otherwise.
Example (b):
as shown in fig. 1, a punch structure comprises a positioning part 1, a cutter rod part 2, a transition part 3 and a cutter head part 4, wherein the positioning part 1, the cutter rod part 2, the transition part 3 and the cutter head part 4 are sequentially and fixedly connected from top to bottom, the cross section of the positioning part 1 is quincunx, the positioning part 1 with the end surface in the quincunx shape can prevent the positioning part 1 from rotating in a mounting hole, the transition part 3 is used for fixedly connecting the cutter rod part 2 and the cutter head part 4, the bottom end surface of the cutter head part 4 is an inclined surface, the inclination angle of the bottom end surface of the cutter head part 4 is 2 degrees, the contact area of the bottom end of the nose portion 4 with the die-cut material gradually increases during the downward die-cutting of the nose portion 4, so that the punching perimeter is synchronously and gradually increased, the whole punching force in the punching process is reduced, in order to make the service life of the cutter head part 4 longer, the surface of the cutter head part 4 is provided with a degree Cr layer of 3um-5 um.
In the embodiments of the present disclosure, the terms "mounting," "connecting," "fixing," and the like are used in a broad sense, for example, "connecting" may be a fixed connection, a detachable connection, or an integral connection; "coupled" may be direct or indirect through an intermediary. The specific meanings of the above terms in the embodiments disclosed in the present invention can be understood by those skilled in the art according to specific situations.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
