There is technical problem in the current edge rolling frock: at the mould during operation, need place the semi-coil material that the preliminary treatment process formed in the standing groove, then the position of rethread bolt regulation fixed pressing block is fixed with semi-coil material work piece, and the position of fixed pressing block is all adjusted to work piece of every shaping by the manual work, and very consume the manual work, and inefficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a simple rounding tool for a press, which realizes self limiting of an upper module and a lower module by arranging a limiting groove and a limiting block, does not need manual fixing, can be directly extruded and molded by the press, is simple, convenient and quick to manufacture and improves the efficiency.

The technical purpose of the utility model is realized by the following technical scheme: the die comprises an upper die block and a lower die block, wherein the upper die block is arranged on the lower die block, a male die forming groove is formed in the upper die block, and a female die forming groove is formed in the lower die block.

The utility model is further provided with: the male die forming groove is of a concave semicircular structure, and the female die forming groove is provided with a concave plane part.

The utility model is further provided with: the upper die is provided with a first limiting block, the first limiting block is far away from one end of the concave plane portion, the concave die forming groove is provided with a limiting groove, and the limiting groove is used for containing the first limiting block.

The utility model is further provided with: the lower module is provided with a second limiting block, the concave plane part is arranged in the middle of the upper module, a stop block is arranged above the concave plane part, and the stop block and the second limiting block can just accommodate the lower end of the upper module.

The utility model is further provided with: when the upper module is arranged on the lower module, the height of the upper module is higher than the highest position of the lower module.

Compared with the prior art, the utility model has the beneficial effects that: the upper die block and the lower die block can be self-limited, do not need auxiliary fixing limitation, can be directly placed on a press machine for extrusion forming, and are convenient and fast and easy to manufacture. Firstly, the upper module is preliminarily limited by a first limiting block and a limiting groove; then, secondary limiting is carried out on the upper module between the second limiting block and the stop block, and the upper module is installed on the lower module to play a role in guiding. When the upper module is arranged on the lower module, the height of the upper module is higher than the highest position of the lower module, so that the press machine can press the upper module down conveniently.
