Furthermore, a detachable connecting structure is arranged between the male die and the male die base.

The utility model has the advantages that: when the hole flanging machine is in actual use, the outer diameter of the male die is gradually reduced from large to small, when a workpiece is subjected to hole flanging processing, the hole flanging processing of the workpiece can be realized at one time along with the downward movement of the male die, a new male die does not need to be replaced, and the processing efficiency is greatly improved. The utility model discloses compare in traditional technology, integrated to a terrace die with the terrace die that a plurality of external diameters are different to optimized the technology of production and processing, realized the effect that the hole flanging was accomplished promptly to one time operation. The utility model discloses be particularly useful for among the ultrahigh strength steel hole flanging processing.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Labeled as: the workpiece comprises a workpiece 1, a female die 2, a male die 3, a first step 31, a second step 32, a third step 33, a gradual transition surface 34, a male die base 4 and a female die base 5.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The ultrahigh-strength steel hole flanging die structure shown in fig. 1 comprises a die base 5 and a die 2 arranged on the die base 5, a convex die base 4 and a convex die 3 arranged on the convex die base 4, wherein the outer diameter of the periphery of the convex die 3 is smaller than the aperture of an inner hole of the die 2, and the outer diameter of the convex die 3 is gradually reduced from large to small along the direction of the convex die base 4 towards the die base 5.

For the hole flanging processing of the ultrahigh-strength steel, due to the limitation of materials, processing standards and the like, the existing hole flanging processing mode is as follows: firstly, a workpiece 1 is arranged on a female die 2, then a first male die with the smallest aperture is selected for carrying out primary pressing hole flanging, after the hole flanging is completed, the first male die is lifted upwards and separated from the workpiece 1, then the first male die is taken down, then a second male die with a slightly larger outer diameter is replaced, the hole flanging is completed again, the hole is enlarged, then the second male die is lifted again, and the like. The mode is low in machining efficiency, and the hole flanging precision is greatly reduced, because the coaxiality of different male dies is difficult to guarantee when the male dies are replaced every time. The utility model discloses ingenious terrace die with above-mentioned each aperture has carried out creative integration, assembles into a terrace die 3, wherein, on along terrace die base 4 towards die base 5 directions, also in the direction of pushing down, terrace die 3's external diameter size is for reducing gradually by big to little. As shown in figure 1, the hole flanging operation which can be finished by pressing down for multiple times originally can be finished by pressing down for one time, the production efficiency is greatly improved, the precision requirement of hole flanging is also ensured, the production efficiency is improved, and the product precision is greatly improved. The utility model discloses think about ingenious, technical advantage is very obvious, and market promotion prospect is wide. Generally, in order to ensure the machining precision, the female die 2 and the male die 3 are preferably arranged coaxially.

As an optimized solution, when only two steps are needed for hole flanging, such a solution can be selected: the outer diameter of the male die 3 is divided into a first step 31 and a second step 32, wherein the outer diameter of the second step 32 is larger than that of the first step 31, and the second step 32 is arranged between the first step 31 and the male die base 4. As shown in fig. 1, the outer diameter of the second step 32 is larger than that of the first step 31, and in actual use, the workpiece 1 is first flanged through the first step 31, and then the workpiece 1 is flanged through the second step 32, so that two steps can be completed in one operation. In order to ensure a smooth transition between the first step 31 and the second step 32, as shown in fig. 1, it is preferable that the first step 31 and the second step 32 are smoothly transitioned by a gradual transition surface 34.

Based on the same concept, when the hole flanging needs three steps, the method can be further optimized on the basis of the scheme: the punch 3 comprises a third step 33, the outer diameter of the third step 33 being greater than the outer diameter of the second step 32, the third step 33 being arranged between the second step 32 and the punch base 4. It may also be preferred that the transition between the third step 33 and the second step 32 is smooth via a gradual transition surface 34.

In order to increase the flexibility of the male die 3 in processing different sizes, a detachable connecting structure is preferably arranged between the male die 3 and the male die base 4. Wherein, terrace die 3 can set up on terrace die base 4 through modes such as threaded connection, draw-in groove joint, when needing to be changed terrace die 3, also can nimble take off and change.
