Rolls are compartments The main part of the board equipment, the design of the rolls often have to pass this part. The following is a brief introduction to the characteristics of the design of the roll plate equipment using the roll.

The main part of the car board equipment is the roll. The design of the roll is very important, and its design features are as follows:

1. The average force principle of each lane of the car board equipment, the average force of the roller, the wear level is balanced, and the service life of the roll is increased.

2, the material used in the roll is to use its wear resistance, but the specific strength and hardness are contradictory. When heat treatment, the red hardness of C12MoV should be utilized. After quenching, the hardness can be achieved by tempering twice to three times. .

3, the orbital arc part is the main part of the car panel equipment, the arc position after the first few press forming, in the subsequent pass rolling up the vertical edge, the upper arc should be formed, through the upper and lower Roller or crossbar to protect the bundle. Otherwise, the arc position of the material changes during the stretching process, and R becomes smaller and becomes a triangle. When the shape R becomes larger, the rail is swayed, the force is uneven, the rail is deformed, and the service life is reduced.

4, rolling stability problem, the production often encounters the problem of material yaw in the raceway, in fact, the single set of rollers is asymmetrical, the left side is stressed, the material is yawed to the right The right side is stressed and the material is yawed to the left.

Welding technology uses laser welding and automatic welding of circumferential seams. The following is a small series to tell you about the advantages of welding machining of four compartment panels.

The advantages of welding processing are reflected in the following four aspects:

1. Ultrasonic welding: advantages, controllable solder joints, smooth welding surface, cheaper equipment, cheaper parts ;

2, laser welding: advantages, solder joints can be controlled high, energy is large and concentrated, combined with firm;

3, precision resistance welding machine: advantages, solder joint controllability Strong, cheaper equipment, smooth welding surface, simple operation, low environmental requirements;

4, micro arc spot welding: advantages, cheap accessories, smooth welding surface, solid combination, wide welding range, accessories Cheaper;
