Description
Technical Field
The utility model relates to a panel punching press technical field, in particular to a be used for reaming terrace die of panel.
Background
The punch is a metal part on a stamping die in a mechanical tool, is called a stamping rod, a stamping needle or a punch, is arranged on the stamping die to perform continuous punching, stamping and breaking operation, and leads the processed material to be separated or plastically deformed, thereby obtaining the required finished product or semi-finished product.
The reaming is as common characteristic on the automobile parts, and present reaming mould design is comparatively single, can adopt the drift to carry out the reaming test. The punches required are different for the requirements of the hole expansion ratio of the material. However, in the prior art, the punch and the base are integrally formed, and when the requirements of different hole expansion rates of materials are met, the punch and the base need to be replaced together, so that the cost is high, and the operation is inconvenient.
SUMMERY OF THE UTILITY MODEL
The utility model provides a be used for reaming terrace die of panel has solved or partly has solved drift and base integrated into one piece among the prior art, when facing the requirement of the different reaming rates of material, needs to change drift and base together, leads to with high costs, the inconvenient technical problem of operation.
In order to solve the technical problem, the utility model provides a be used for reaming terrace die of panel includes: a base and a reaming head; the reaming head comprises: a punch and a connecting portion; the punch is fixedly connected with the connecting part; the end part of the connecting part, which is far away from the punch, is detachably connected with the base; the connecting part is provided with a first hole, and the base is provided with a second hole.
Further, a stud is fixedly arranged on the end part, away from the punch, of the connecting part; the end surface of the base facing the connecting part is provided with a threaded hole; the stud is disposed within the threaded bore.
Further, the punch is conical in shape.
Further, the punch is cylindrical in shape.
Further, the shape of the punch is hemispherical.
Further, the shape of the end face of the connecting part facing the base is matched with the shape of the end face of the base facing the connecting part.
Further, the size of the end face of the connecting part facing the base is matched with the size of the end face of the base facing the connecting part.
Further, the shape of the punch toward the end face of the connecting portion matches the shape of the end face of the connecting portion toward the punch.
Further, the dimension of the punch toward the end face of the connecting portion matches the dimension of the connecting portion toward the end face of the punch.
One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:
because drift and connecting portion fixed connection, connecting portion deviate from the tip of drift and are connected with the base detachablely, so, when the requirement of the different reaming ratio of face to the material, dismantle connecting portion from the base, it accords with the drift that the reaming ratio required to change, therefore, the cost is saved, because the first hole has been seted up on the connecting portion, the second hole has been seted up on the base, so, when will changing the drift, insert first hole and second downthehole respectively with two connecting rods, utilize lever principle, the connecting portion of being convenient for carries out the dismouting on the base, and convenient operation.

Detailed Description
Referring to fig. 1, an embodiment of the present invention provides a male die for reaming a plate, including: base 1 and reaming head 2.
The reaming head 2 comprises: a punch 2-1 and a connecting part 2-2.
The punch 2-1 is fixedly connected with the connecting part 2-2.
The end of the connecting part 2-2 facing away from the punch 2-1 is detachably connected with the base 1.
The connecting part 2-2 is provided with a first hole 3, and the base 1 is provided with a second hole 4.
According to the specific embodiment of the application, the punch 2-1 is fixedly connected with the connecting part 2-2, and the end part of the connecting part 2-2, which is far away from the punch 2-1, is detachably connected with the base 1, so that when the punch meets the requirements of different hole expansion rates of materials, the connecting part 2-2 is detached from the base 1, the punch 2-2 meeting the requirements of the hole expansion rate is replaced, and the cost is saved.
Specifically, a stud 5 is fixedly arranged on the end part of the connecting part 2-2 departing from the punch 2-1;
the end surface of the base 1 facing the connecting part 2-2 is provided with a threaded hole 6;
the stud 5 is disposed within the threaded hole 6.
When the punch 2-1 needs to be replaced, the stud 5 is rotated in the threaded hole 6, the connecting part 2-2 is separated from the base 1, then the stud 5 on the connecting part 2-2 to be replaced is inserted into the threaded hole 6 to rotate, and the punch 2-1 to be replaced is installed on the base 1.
Referring to fig. 2, the punch 2-1 is conical in shape.
Referring to fig. 3, the punch 2-1 is cylindrical in shape.
Referring to fig. 4, the punch 2-1 is shaped as a hemisphere.
The conical punch 2-1 has the highest hole expansion ratio, the hemispherical punch 2-1 has the medium hole expansion ratio, and the cylindrical punch 2-1 has the lowest hole expansion ratio.
Specifically, the shape of the end face of the connecting part 2-2 facing the base 1 matches the shape of the end face of the base 1 facing the connecting part 2-2. The size of the end face of the connecting part 2-2 facing the base 1 is matched with the size of the end face of the base 1 facing the connecting part 2-2, so that smooth reaming is ensured.
The shape of the end face of the punch 2-1 facing the connecting part 2-2 matches the shape of the end face of the connecting part 2-2 facing the punch 2-1. The size of the punch 2-1 facing the end face of the connecting part 2-2 is matched with the size of the connecting part 2-2 facing the end face of the punch 2-1, so that smooth reaming is ensured.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
