Problems solved by technology

In the prior art, 90° flare and sharp-angle bending are formed by adopting structures such as starting line, springback, and slider forming. The starting line must not only be confirmed by the customer, but it is also prone to cracking during bending; It is necessary to adjust the shaping station, which increases the mold station and processing cost; the slider method is complicated to process, the cost is high, and the maintenance cost after the slider breaks is high; High, the production is not stable enough

Abstract

The invention relates to a progressive die 90-degree outward-opening adjustment and acute-angle bending structure which comprises a fixing insert. A counter bored hole is formed in one end of the fixing insert, an ejection pin is installed at the lower portion of the counter bored hole, and a set screw is arranged at the top end of the counter bored hole and is connected with the ejection pin through a spring. A swing punch is installed under the fixing insert and is structurally that an outwards-protruding puncher pin is arranged in the middle of the upper top face of the swing punch, the upper top faces on two sides of the swing punch are oblique planes, a right-angle gap is formed in the right side of the lower end of the swing punch, and a transition circular arc is arranged at the position of the right-angle gap. The progressive die 90-degree outward-opening adjustment and acute-angle bending structure further comprises a lower die insert core, wherein a bending structure matched with the right-angle gap of the swing punch is arranged at the left end of the lower die insert core. The progressive die 90-degree outward-opening adjustment and acute-angle bending structure is low in machining difficulty and cost, simple and convenient to assemble, good in forming stability and high in forming accuracy and facilitates die repair.

Description

technical field [0001] The invention relates to the technical field of bending dies, in particular to a 90° external tension adjustment and acute angle bending structure applied to continuous dies. Background technique [0002] The continuous die refers to the cold stamping die that the press uses several different stations to complete multiple stamping processes at the same time in one stamping stroke. Every time the stamping is completed, the material belt moves once at a fixed distance to the product. Finish. The continuous mold is widely used, covering many fields, with high forming precision, high production efficiency, safety and stability. In the prior art, 90° flare and sharp-angle bending are formed by adopting structures such as starting line, springback, and slider forming. The starting line must not only be confirmed by the customer, but it is also prone to cracking during bending; It is necessary to adjust the shaping station, which increases the mold station ...
