In recent years, as China's overall economy has advanced by leaps and bounds, business operations are gradually moving towards scale. Scale and localization should be said to be complementary. Only by developing products that are suitable for the local market can companies enter the local market and achieve greater scale. To invest in localization, they must expand their scale to recover their investment. Maybe now many people are not very clear about cold roll forming machines. The Cold Roll Forming Machine Manufacturer will take you to understand, then you will soon find that the help he can bring to all of us is great.
Cold forming machine working principle:
1. Cold Roll Forming Machine average load principle of each pass, the average load of the rollers across the line, wear balanced, and extend the life of the roll.
2. The rolls of the cold roll forming machine use the material to take advantage of its wear resistance, but the specific strength and hardness are contradictory. After quenching, the hardness can be reached by two or even three tempering.
3. The arc part of the track is the core part of the slide rail. The arc positions after the first several passes are formed. When the vertical edges are rolled in the subsequent passes, the formed arc should be protected by the upper and lower rolls or horizontal wheels for effective tube bundle protection. Otherwise, the arc position will definitely change during the stretching process. R becomes smaller to become a triangle, and the steel ball is not at the end. Two-point contact will generate noise. When R becomes larger, the matching track will sway, and the track will be blurred during use. Uneven force, deformation of the slide rail, shortened life.
4. The stability of rolling. The problem of material swaying left and right in the raceway is often encountered in production. In fact, a single set of rollers is subject to asymmetry. Sway to the left.

Precautions when using cold roll forming machine:
1. Be sure to adjust the pressing speed according to the properties of the processing materials and the curvature of the processing to prevent the workpiece from breaking and splashing.
2. The cold bending forming machine must be under the direction of a special person when working with multiple people. The foreman must give instructions to other personnel to cooperate with the close action when the processing part enters and withdraws. Do not place your hand between the roller of the feeding rack and the workpiece.
3. For the selection of the slot of the cold-bending forming machine, a slot with a width of 8 times the plate thickness is generally selected. If you bend a 4mm sheet, you need to choose a notch of about 32.
4. When the top pad needs to be moved according to the curvature of the workpiece, the contact between the top pad and the head is not less than two-thirds. The contact between the beginning and end of the workpiece and the support pad should exceed the center line of the support pad. When bending profiles with large curvatures, people are not allowed to stand at the ends.
The above are the features and applications of the cold roll forming machine introduced by the Steel Door Frame Roll Forming Machine supplier. Hope to help everyone.
