Description

Technical Field

[0001] The invention belongs to the technical field of profile stamping, and provides a profile stamping die which can adapt to aluminum profiles of different specifications, has a punch that can be quickly disassembled and assembled, and has precise guidance, and in particular relates to an adaptive stamping die for aluminum profiles. Background Art

[0002] In modern industrial production, aluminum profiles are widely used in many fields such as construction, automobiles, aerospace, electronic equipment, etc. due to their many excellent properties such as light weight, high strength, corrosion resistance, and recyclability. Stamping is one of the important processes for aluminum profile processing, and the performance of its mold directly affects the quality and production efficiency of aluminum profile products.

[0003] At present, there are many shortcomings in the existing aluminum profile stamping dies. On the one hand, traditional aluminum profile stamping dies lack effective adaptive adjustment capabilities when facing aluminum profiles of different specifications and shapes. For aluminum profiles of different widths, thicknesses or cross-sectional shapes, existing dies often need to replace the entire set of dies or perform complex adjustment operations to meet the stamping requirements, which not only increases production costs and time costs, but also reduces production efficiency. During the stamping process, since the mold cannot accurately adapt to the characteristics of the aluminum profile, it is easy to cause quality problems such as deformation and cracks in the aluminum profile, affecting the performance and appearance of the product.

[0004] On the other hand, the existing aluminum profile stamping dies have the problems of cumbersome operation and long time consumption in the installation and disassembly of the punch. As a key component of the mold, the punch is prone to wear after long-term use and needs to be replaced in time. However, traditional punch installation structures mostly use bolt fastening or pin positioning methods. These methods require tightening the bolts or inserting the pins one by one during installation. The operation process is complicated and time-consuming. It also takes a lot of time to loosen the bolts or pull out the pins during disassembly. After multiple disassembly and assembly, the bolt holes or pin holes are prone to wear, affecting the installation accuracy and stability of the punch.

[0005] In addition, the existing aluminum profile stamping dies also have shortcomings in profile guiding. During the stamping process, accurate guiding of the aluminum profile is crucial to ensuring the stamping quality. However, the existing die guiding mechanism often has a simple structure and cannot be flexibly adjusted according to the specifications and shape of the aluminum profile, causing the aluminum profile to easily shift or shake during the stamping process, affecting the stamping accuracy and product quality.

[0006] In summary, a punching machine capable of adapting to aluminum profiles of different specifications and shapes is developed. Summary of the invention
