Description
Technical Field
[0001] The utility model relates to the technical field of stamping limit devices, in particular to a stamping limit device for automobile parts. Background Art
[0002] Auto parts are the components that make up the whole car. They include various functional parts, structural support parts, and exterior decorative parts. The stamping process is the process of processing metal sheets through dies to make them into parts of the required shape. The stamping limit device ensures the positioning accuracy of the parts by limiting and controlling the position of the parts in the die. This is crucial to ensure the consistency of the size, shape, and position of the parts to ensure the assembly accuracy between the parts and the quality of the overall product. Therefore, an auto parts stamping limit device is needed.
[0003] When an existing stamping limit device for automobile parts is used, a metal plate is stamped through a stamping structure. The guide tube and the guide column in the stamping structure play a limiting role to prevent the upper mold and the lower mold from being misaligned during stamping. The metal plate can be limited by a limit block to prevent the metal plate from deviating during work, resulting in poor part forming quality. The stamped parts can be quickly dropped off by a movable rod and a pressure block, and the formed parts can be collected by a collection box. However, this method cannot clamp and fix parts of different sizes when used. When the stamping limit device cannot adapt to parts of different sizes, it cannot provide sufficient clamping force and stability, resulting in the parts moving, shaking or deforming during the stamping process, making it impossible for them to maintain the required accurate position and shape, which easily leads to an increase in the generation rate of product scrap.
