Description

Technical Field

[0001] The utility model relates to the technical field of inclined wedge dies, in particular to an upward-slope walking inclined wedge mechanism. Background Technique

[0002] Traditional inclined wedge mechanisms are generally divided into three forms. One is the horizontal inclined wedge, another is the suspended inclined wedge, and the other is the so-called stripper plate inclined wedge installed in the stripper plate. These three inclined wedges all have certain limitations. For example, the horizontal inclined wedge is only applicable to products with an angle of 85° - 90°, while the suspended inclined wedge can basically meet the requirements when the product angle is between 0° - 75°. The stripper plate inclined wedge has even greater limitations. It can only be used when the product angle is relatively gentle (such as 5° - 15°), and the stripper plate inclined wedge die occupies a large space, has an unstable structure, and is prone to burrs during production. When encountering special product angles (such as 100° - 150°), the above three inclined wedge mechanism methods are difficult to meet the requirements. Summary of the Invention
