The forged piece with flash is composed of a body and flash, and is shown in figure 1.
After forging, the flash is usually removed by mechanical cutting or trimming by a trimming die, and after the forging is mechanically cut into the flash, the forging is often required to be returned to the die forging process for heating to carry out the correction process, so that the deformation caused by cooling or other reasons of the forging is eliminated. Therefore, the more common method is that the forged piece is preheated after being forged, the hot trimming of the forged piece is carried out by adopting the trimming die, and the trimming die directly returns to the die cavity for correction, so that the production and manufacturing process and period can be shortened to the maximum extent, the production and manufacturing efficiency is improved, and the manufacturing cost is reduced.
The trimming die is usually installed on an oil press or a friction press in a trimming die holder mode, the traditional design method of the trimming die holder is designed according to the size of the trimming die, the traditional design method of the trimming die holder is integral casting, and the material range ZG257 comprises a base, a support body and a pressure-bearing face, which is specifically shown in fig. 2.
The size of traditional side cut die holder pressure-bearing surface can't be adjusted according to the size of trimming die, therefore different trimming die need match different side cut die holders and use. Therefore, as long as the sizes of the trimming dies are different, a new trimming die holder needs to be added to meet the use requirement. The method brings great investment and waste and also brings great challenge to the field occupation of the manufacturing site.
