Forging force calculation method of hot die forging machine

Dec 30, 2017

The hot die forging machine has brought great help to many users by virtue of its own superior performance. First of all, the hot die forging machine not only has high efficiency, simple operation, but also convenient for maintenance and maintenance. Therefore, for the users, the hot die forging machine is not only easy to operate, but also can effectively reduce the cost of production. Secondly, the special design of the transmission system of the hot die forging machine can reduce the noise pollution.

In addition to these advantages above, in the process of using hot die forging machine can also be reset in a relatively short period of time, coupled with the double guide path design, this can achieve the anti roll slope is higher, and can be used for multi station forging, forging quality. More importantly, the precision of the product is high, and it has fully reached the CNS inspection standard of the National Central Standard Bureau.

In comparison, the forgings made by the hot die forging machine not only have higher precision, but also have few processing allowance, which can satisfy the temperature and heat forging work. However, in the process of forging, we need to calculate in order to ensure the selection of suitable equipment, make the quality and accuracy of the produced forgings stable, achieve higher productivity, and give full play to the superior performance of the equipment.

At present, there are many ways to calculate the forging force of the hot die forging machine. Most of them are empirical formulas of scholars, experts and technical workers engaged in the production and research of die forging. One of the formulas is the open die forging force formula, that is, P = (50~70) F, where the letter P represents the deformation force, and F represents the projection area of the forgings including the flash bridge.

In practical applications, this formula is mainly used to estimate the deformation force of a certain type of forgings, so as to provide references for selecting a certain type of hot die forging machine. The coefficient in this formula is 50 to 70. When using hot die forging machine, we can choose smaller values when producing some forgings which are simple in shape, larger in transition fillet, larger in external fillet and thicker in wall thickness.
