Continuous stamping method without landing edge

Abstract

The invention discloses a continuous stamping method without a landing edge. The continuous stamping method includes the following steps of: S1, completing punching required by a part on a blank according to design requirements of the part; S2, cutting off the blank according to a designed width; S3, cutting a round corner on the blank according to the design requirements of the part; S4, bending and ribbing the blank according to design requirements of the part; and S5, conducting discharging. According to the continuous stamping method disclosed by the invention, stock layout and components of a mold are optimized, and the key point is how to well feed materials under the condition of being separated from a carrier, how to cut fillets at the two ends after separation and how to feed materials in place.

Description

technical field [0001] The invention relates to the technical field of stamping, in particular to a continuous stamping method without overlapping. Background technique [0002] Such as figure 1 and figure 2 As shown, the L-shaped bracket product is a commonly used product with a wide range of applications, especially in the automotive industry. Generally, the precision grade of L-shaped bracket products is at T12 level, which belongs to parts with low precision requirements, and its size technical requirements are not high. The product has to be plasticized and painted. [0003] Such as image 3 As shown, at the same time, in the prior art, after the rounded corners of the product are cut, because the rounded corners are small, there will be sharp corners near the cut, which poses a safety hazard. [0004] Such as Figure 4 and Figure 5 As shown, the existing layout is to stagger the square holes and round holes of adjacent parts, and the arrangement distance betwe...
