In WILA efficient solution of bending medium and thick plates -  (part I), we introduce the tonnage of press brake bending machine and heavy hydraulic clamp. In this article, we will continue to introduce other factors.


Heavy machinery compensation workbench

For the bending of medium and thick plates, WILA's new-level version of the heavy-duty mechanical compensation table can not only easily meet the load requirements, but also compensate for the deflection and deformation of the bending machine. The mechanical compensation workbench adopts hydraulic clamping, the surface accuracy can reach ±0.01mm, the rockwell hardness is 56~60HRC, and the hardening depth is up to 4mm. The mechanical compensation workbench adopts the universal UPB installation interface of WILA, which is easy to install and has higher accuracy. It also has its own Tx and Ty direction adjustments, which can ensure that the workbench and the backgauge remain parallel in the front and rear directions, and can perform local angular deviation correction.

Heavy bending die/tooling 

Due to the thickness of the plate, the lower mold with larger opening size (V24~V300) and the mold with larger bearing capacity are generally selected for the bending of medium and thick plates. The overall dimensions of the mold are generally large, and the weight of the mold has exceeded the normal handling capacity of the operator. With the help of roller bearings, WILA's patented technology E2M (Easy to Move) allows operators to move heavy bending molds conveniently, safely, and quickly, greatly saving mold replacement and machine adjustment time.

Bending molds with various knife shapes and lower mold openings that meet customer needs can be provided, such as straight knives, gooseneck scimitars, fillet molds, and multi-V molds. Through precise grinding of key parts, the dimensional accuracy of the mold is as high as ±0.01mm. Through the processing of CNC deep quenching and hardening technology, the mold hardness can reach 56~60HRC, and the depth of the hardened layer can reach 4mm.

Heavy bending tooling


For the bending of medium and thick plates with different plate thicknesses, WILA also provides Multi-V molds, which are available in two forms: automatic adjustable V port and manual adjustable V port, as shown in Figure 6. Through the numerical control motor or the adjustment block, the V opening size of the lower mold can be adjusted arbitrarily according to the characteristics of the plate, which is especially suitable for bending medium and thick plates with high rebound and high strength. At the same time, the Multi-V mold comes with hardened rollers with a low friction coefficient, which can greatly reduce the external creases of the bending parts, and at the same time, it can reduce bending by 10%~30% compared with the traditional lower mold.
