Description

Technical Field

[0001] The utility model relates to the technical field of fixed - table presses, and particularly relates to a bending device for an open - type fixed - table press. Background Technique

[0002] A press (including a punching press and a hydraulic press) is a general - purpose press with a delicate structure. It has the characteristics of wide application and high production efficiency. The press can be widely used in processes such as cutting, punching, blanking, bending, riveting, and forming. By applying a strong pressure to a metal blank, the metal undergoes plastic deformation and fracture to be processed into parts. When the mechanical press works, the motor drives the large pulley (usually also serving as a flywheel) through a V - belt, and then drives the crank - slider mechanism through a gear pair and a clutch, so that the slider and the punch move linearly downward. After the forging work of the mechanical press is completed, the slider moves upward, the clutch is automatically disengaged, and at the same time, the brake on the crankshaft is engaged, so that the slider stops near the top dead center.

[0003] The patent network publication number CN 217141840 U discloses a bending device for an open - type fixed - table press, which includes a bottom bracket, a mounting frame fixed on the top of the bottom bracket, a cylinder fixedly installed on the top of the mounting frame, and a pressing die fixed on the output end of the cylinder. A workbench is fixedly connected to the bottom bracket, and two symmetrically arranged support dies are fixedly connected to the workbench. In the utility model, a middle support member, a guide bar, a connecting rod, and a return spring are adopted. The steel bar is arranged in the two support dies, and then the cylinder is started to drive the pressing die to abut against the steel bar to achieve the bending purpose. At this time, the middle support member is pressed and descends. When the bending work is completed, the external force of the cylinder is removed, the guide spring releases elastic force, drives the guide bar to move upward on the two guide rods, drives the middle support member to reset, and at the same time makes the two ends of the steel bar connecting piece separate from the support die, realizing rapid demoulding work and improving the processing efficiency.

[0004] The applicant believes that it has the following disadvantages: When the steel bar connecting piece is placed on the surfaces of the support die and the middle support member for bending, the support die does not have a structure for positioning the steel bar connecting piece. This leads to the phenomenon that the steel bar connecting piece is easily detached during the bending process of the steel bar connecting piece, thus affecting the bending effect of the steel bar connecting piece.
