Fixed Die and Fly Die on Roll Forming Machine

In the process of roll forming machine, die cutting is often used. According to the installation structure and working mode, the die can be divided into fixed die and flying die.

The fixed die is fixed, and the flying die can slide in a section of slide rail. It can move according to the way the profile moves, tracking the profile for punching. The flying die is generally used on more expensive equipment, and the efficiency is very high.

1. Fixed die of roll forming machine

In the auxiliary processing technology of punching and cutting of the profile, the stamping mechanism adopted is similar. However, when designing a fixed die, the subsequent roll forming and other processing procedures must be considered.

Other factors to consider are: the direction of the profile burr, the distance from the punching point to the forming line, how to cut and where to cut the strip locally, the connectivity of the profile, and the effect of warpage at the punching point.

In most cases, the die used in the fixed operation is similar to the die used in the stamping workshop, except that the die mechanism used in the production line of the roll forming machine has a cycle of feed-stop-execute and other processes. These institutions are very common structures, and some factors need to be specially considered when designing. as follows:

1. Product direction.

2. Requirements for subsequent processing of profiles.

3. The final product may be very long.

4. Different length styles.

5. The combination of the initial fixed die and the subsequent flying die.

2. Flying die of roll forming machine

The function of flying die and fixed die is the same, but their structure and installation method are different. The fixed die is on the fixed machine and is used in the production of some specific profiles or on the production line of a roll forming machine with relatively low efficiency.

The flying die can slide on the track, and there is no need to stop the machine during punching, so that the production efficiency of the equipment can be greatly improved.

When the flying die of the roll forming machine is working, it follows the profile. It accelerates from the initial position to the maximum speed, then decelerates, stops, accelerates and decelerates in the opposite direction, and finally stops at the initial position for the entire stroke. The time required is generally between 0.15 seconds and 1.5 seconds.

The acceleration mechanism of the die is generally installed on the fixed plate of the lower die. When accelerating or decelerating, the impact effect produced by the weight of the upper mechanism and the die. Therefore, the flying die of the roll forming machine has stronger support columns and guide rails than the fixed die.
