FIELD: metallurgy.
SUBSTANCE: invention relates to bending machines intended for bending and deforming metal tapes, sheets and profiled sections to produce semi-products or end products. Disclosed is a bending machine for bending sheet metal, comprising piercing means (2), which includes upper crossbar (3), configured to support a plurality of upper bending tools (BT) (40, 41, 42); matrix means (4), including lower crossbar (5) configured to support a plurality of lower BT (30–35); at least one rear thrust assembly (6) configured to thrust against the workpiece and position it relative to female die (4). Rear thrust assembly (6) comprises hook element (7) configured to engage at least one lower BT (30–35). Plurality of lower BTs (30–35) comprises at least one of side lower BT (30) of group (G), which can be engaged with engaging element (7) of rear thrust assembly (6). Side lower BT (30) are made with possibility of reversible connection with each other to form group (G) of side lower BT (30).
EFFECT: technical result is shorter time for performing installation and/or disconnection of tools.
