Description

Technical Field

[0001] The utility model belongs to the field of bending machines, and in particular relates to a single- and double-control plate bending machine. Background Art

[0002] The existing hydraulic sheet metal bending machines mostly use a single foot pedal to control the bending, which brings certain safety hazards to the bending control of large pieces. Generally, large pieces require at least two people to operate at the same time. For example, if one of them makes a mistake or does not coordinate his movements well, it is easy to cause a safety accident. However, for the bending of small pieces, dual control becomes very troublesome and inconvenient to operate. In view of the above situation, we have made special control improvements to the current bending machines. Through a conversion switch, single control and dual control can be easily switched, which can ensure the convenience of single-control bending of small pieces and the safety of bending of large pieces.
