• What are the types of press brake tooling （bending machine molds ）

  Oct 13, 2025

  Classification of commonly used press brake tooling: There are several types of bending tools, including L-shaped, R-shaped, U-shaped, Z-shaped, etc. The upper punch mainly has different angles such as 90 °, 88 °, 45 °, 30 °, 20 °, and 15 °. There are double and single slots with different slot widths of 4-18V in the lower dies, as well as R lower mold, acute angle lower mold, flattening tool set, etc. press brake tooling punch and die are divided into sections and whole parts: the upper punch is generally divided into sections of 300mm, 200mm, 100mm, 100mm, 50mm, 40mm, 20mm, 15mm, 10mm, and the whole is 835mm. The lower die is generally divided into sections of 400mm, 200mm, 100mm, 50mm, 40mm, 20mm, 15mm, and 10mm, and the whole is 835mm. ① Bending tools are made o...

• Maintenance and upkeep of the press brake

  Oct 11, 2025

  Before performing machine maintenance or cleaning, the upper punch should be aligned with the lower dies and the machine should be lowered and turned off until the work is completed. If startup or other operations are required, the mode should be selected as manual and safety should be ensured. The maintenance content is as follows:   1. Hydraulic oil circuit 1) Check the oil level in the fuel tank every week, and also check it after hydraulic system maintenance. If the oil level is below the oil window, add hydraulic oil; 2) The hydraulic oil used in this machine is ISO HM46 or MOBIL DTE25; 3) The new machine should have its oil changed after 2000 hours of operation, and every 4000-6000 hours of operation thereafter. After each oil change, the oil tank should be cleaned; 4) The syste...

• 4 Flattening Bending Solutions For Press Brake Tooling -Hemming Die

  Oct 02, 2025

  The following 4 flattening bending solutions. 1. The traditional way is to change the press brake hemming dies.         2. The Spring Hemming die is used. There is no need to change the mold during the whole process. The top notch is folded and the sharp corner is bent, and the second side bounces the part to flatten the edge in one go.   3. Pneumatic hemming die, it cancels the second spring design and uses a pneumatic device instead. It can be opened when it needs to be flattened, which is more scientific.   4. The U-shaped lower die cooperates with the integrated upper punch for bending and flattening, adjusting the bending stroke to complete job   Jaminnar Press brake hemming dies with spring for flatten, we can change the v opening according...
