Automatic core penetrating and pulling device for stretch bending

Abstract

The invention relates to an automatic core penetrating and pulling device for stretch bending. The automatic core penetrating and pulling device comprises a 'U'-shaped clamping base which is formed bya first fixing surface, a second fixing surface and a connection surface, the first fixing surface and the second fixing surface are opposite, and the connection surface is positioned between the first fixing surface and the second fixing surface. The connection surface is provided with a through hole, a guide block with a penetration hole is arranged in the through hole, a driving oil cylinder is arranged on one side opposite to an open face of the clamping base, and a connector is arranged at the end of a cylinder rod of the driving oil cylinder. A static clamping block is arranged betweenthe penetration hole and the first fixing surface, a sectional material clamping plate is arranged between the static clamping block and the connection surface, and a 'U'-shaped sectional material supporting block is arranged on one side, opposite to the penetration hole, of the static clamping block. A movable clamping block is arranged between the penetration hole and the second fixing surface and positioned between the inner side of the connection surface of the clamping base, the second fixing surface is provided with a slot hole, and a driving mechanism for controlling the movable clamping block to move is arranged in the slot hole. The automatic core penetrating and pulling device for stretch bending is structurally simple and reasonable, convenient to use, quick and efficient.

Description

technical field [0001] The invention relates to the technical field of stretch-bending equipment, in particular to a stretch-bending automatic core-piercing and core-pulling device. Background technique [0002] In the production of straight-line skeleton stretch-bending parts, in order to ensure that the section of the straight-line profile does not deform during the stretch-bending process, a flexible material core is usually inserted into the straight-line profile. The traditional core-pulling mechanism is independent of the bending mold, and the movement of the core is driven by the oil cylinder on this independent mechanism, which requires the long straight parts to be manually transported to this mechanism for operation after bending, and then manually connect the head The connection requires workers to reciprocate between the mold and the mechanism, which wastes space, wastes work cycle time and wastes manpower.
