Description

Technical Field

[0001] The utility model relates to the technical field of integrated molds for bending, forming and punching automotive anti-collision beams, and specifically relates to a structure of an integrated mold for bending, forming and punching automotive anti-collision beams. Background Technique

[0002] During the normal driving of a vehicle, when it collides with a vehicle or an obstacle in the forward direction and receives a local impact, the front anti-collision beam needs to ensure sufficient strength and stiffness to prevent the front anti-collision beam from breaking due to a strong impact and hurting the passengers in the vehicle and important components inside the vehicle.

[0003] When the existing integrated mold for bending, forming and punching automotive anti-collision beams is used for production and manufacturing, the anti-collision beam material is bent and formed through a pre-prepared mold. For example, an integrated mold structure for bending, forming and punching automotive anti-collision beams with the application number "202322077285.6" includes a mold base, an upper mold, a mold cavity plate, a lower mold, an oil cylinder seat, a bending drive seat and a bending rod. The upper mold is fixedly installed at the front of the mold base, and two mold cavity plates are fixedly installed on the upper and lower sides of the mold base. The lower mold is fixedly installed inside the two mold cavity plates. A bending mold cavity is formed between the two lower molds and the upper mold. The bending rod is fixedly installed on the bending drive seat. During the bending process of the profile, there is a sliding friction displacement between the profile and the lower mold. After the lower mold is worn, it can be separately disassembled and replaced to reduce the maintenance and replacement cost. At the same time, by replacing the upper mold, the mold cavity plate and the lower mold with different arcs together, it can meet the bending and forming processing requirements of anti-collision beams with different bending arcs. When the processed and formed anti-collision beam is fixed on the mold without being removed, a stamping positioning hole operation is performed on it.

[0004] However, the existing integrated mold for bending, forming and punching automotive anti-collision beams can only bend and form limited anti-collision beam materials. When anti-collision beam materials of different specifications and models appear, a set of molds needs to be replaced to process the materials, which reflects the singularity of the mold.
