CNC Reeling Steel Plate Parts
There Are Three Main Types Of Steel Plate Bending Service, Which You Can Perform On a Pressure Brake:
Steel Plate Bending Is Used To Create u-Shaped, v-Shaped Or Groove-Shaped Along The Horizontal Axis In Ductile Materials Such As Sheets. Common Equipment Used In This Manufacturing Process Includes Brake Presses, Box And Disc Brakes And Other Professional Presses.
In The Forming Process Of The Pressing Brake, a Workpiece Is Placed On The Pressing Die, Which Presses The Sheet Metal Into The Desired Shape. When The Bending Is Completed, The Material Will Attempt To Rebound Its Initial Position; Therefore, The Workpiece Must Be Over-Bended To Achieve The Desired Angle. Springback Depends Entirely On The Workpiece Material And Bending Type.
Air Bending – The Principle Of This Process Is To Press The Punch Onto The Workpiece And Then Press It Into The v-Shaped Die At The Bottom. The Die Is Mounted On The Press. The Punch Creates Bending So That The Space Between The v-Shaped Side Wall And The Punch Is Larger Than The Thickness Of The Workpiece. Because This Process Requires Less Bending Force, It Tends To Use Smaller Tools Than Other Technologies. Air Bending Is Very Flexible, Allowing Many Different Materials And Thickness To Bend At Different Angles. Compared With Other Methods, This Process Requires Fewer Tool Changes, Which Means Higher Productivity.
Bottoming – In This Technique, The Sheet Metal Is Pressed On The v-Shaped Opening Of The Bottom Tool. There Is a Certain Space Between The Bottom Of The v-Shaped Opening And The Workpiece. This Method Provides Higher Accuracy And Less Springback, But Different Materials, Bending Angles And Thicknesses Require Different Toolsets.
Die-Pressing – In The Process Of Die-Pressing, The Upper Tool Press Material Down Into The Lower Die With 5-30 Times The Bending Power Of Air. This Results In Permanent Deformation Of The Workpiece And Almost No Rebound (If Any). This Method Has High Accuracy.
