Description

Technical Field

[0001] This utility model relates to the field of integrated stamping and bending tooling technology, and in particular to a novel integrated stamping and bending tooling. Background Technology

[0002] In modern manufacturing, the processing technology of metal parts plays a crucial role in product quality, production efficiency, and cost control. Stamping and bending, as two common metal processing techniques, are widely used in many fields such as automobile manufacturing, electronic equipment, home appliances, and aerospace to produce metal parts of various shapes and specifications.

[0003] Traditionally, stamping and bending processes are usually performed separately, requiring different tooling and equipment. In the stamping process, a punch press and corresponding stamping dies are used to punch and blank sheet metal according to a predetermined shape, resulting in a preliminary part blank. Subsequently, a bending machine and bending dies are used to bend the stamped part to achieve the final design shape and dimensional accuracy requirements. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This utility model provides a novel integrated stamping and bending tooling, which has the following beneficial effects:

[0016] 1. This novel stamping and bending integrated tooling, through the setting of the bending mechanism, allows the connecting plate to move downwards during stamping, driving the two upper protrusions at the bottom to slide on the lower protrusion surface of the worktable. The lower protrusions slide on the positioning rod surface under force and compress the support spring on the positioning rod surface. When the sliding plate moves relative to the workpiece, it will drive the bending plate on one side to move on the lower die surface, thereby achieving the effect of bending the side of the workpiece during the stamping process. It can perform stamping and bending steps on the workpiece simultaneously without separate operations, thus improving the efficiency of workpiece processing.

[0017] 2. This new type of stamping and bending integrated tooling, through the setting of the demolding mechanism, when the workpiece is stamped and squeezed, several demolding modules at the bottom are pressed. When the workpiece surface loses the pressure of the upper die, the demolding modules are subjected to the reverse force provided by the torsion springs on both sides, and drive the demolding modules to rotate, lifting the processed parts on the surface of the demolding modules, thereby achieving the effect of rapid demolding, making it convenient for workers to pick up the workpiece and operate.

[0031] In this invention, the working steps of the device are as follows:

[0032] First step: During the stamping process, the connecting plate 1001 moves downward and drives the two upper protrusions 503 at the bottom to slide on the surface of the lower protrusion 502 on the surface of the worktable 1.
