The structure design of Tandem Press Brake is as follows:
The tandem press brake machine consists of two press brakes, the 1st and the 2nd press brake, both of which are designed with a worktable. The worktable is fixed with a lower die, and each end of the press brake is equipped with a side plate.
On the 1st press brake, the worktable and the lower die are extended out on one side-plate and then stretched to the inside side-plate of the 2nd press brake, where they are spliced together with the worktable and the lower die of the 2nd press brake.
The joint seams at the splicing point between the worktable and low die of the 1st and 2nd press brake are very small, measuring under 1mm. This is due to the fine finishing surface of the worktable and the end of the low die.
When operating the tandem press brake, the joint seams position exhibits high bending accuracy without any special-shaped transition zone.
The tandem press brake model is particularly suitable for sheet materials with a bending length that exceeds the width of a single press brake.
