2023年2月24日 · Blanking and cutting of tubes is highly productive with small burrs in the cut. However, in order to prevent the tube wall from being flattened, a normal blanking die or shear cannot be used, but a convex die with a plate tip should be used. For mass production, the double blanking method is used.

In order to prepare a carbon-fiber-reinforced polymer composite (CFRP) with ideal microstructure and properties, a new vacuum pressure infiltration CFRP method is proposed based on an analysis of...

Based on the analysis of the grid distortion, the range of deformation zones and relative velocity distribution in the outlet region, the best convex die geometry in comparison with others has...

2024年11月15日 · Five methods to reduce the unevenness of stamping parts： 1. Inspection and correction of drawing die: The drawing die needs regular inspection and maintenance to reduce the occurrence of convex and concave and maintain a stable state.

Covex Dies feature very domed convex faces. Although in some aspects similar to the fuller and drawing dies, the convex die differs from the fuller by having a more convex face, and differs from drawing die by having more surface area. Although less aggressive then a drawing die, the convex die is suited to drawing amo

2024年10月4日 · Deep drawing is a stamping and forming process in which a flat sheet is formed into an open hollow part through a concave die under pressure of a convex die. In all types of sheet metal components, deep drawing is often used for the processing of various cylindrical parts, hemispheres and parabolic heads of larger size or thicker material.

2020年1月9日 · When punching, the convex and concave dies must be in friction with the blanking part of the waste. As an Auto Stamping Parts Exporter, the following principles need to be considered when determining the die edge size and its manufacturing tolerances: 1.

Sketch of hydroforming: (a) concave die, (b) convex die. Fuel cell constitutes from different components, among which bipolar plates are the important and expensive part. Nowadays, the...

2022年8月8日 · The convex die wears too fast (1) The clearance of the die is small, generally, the total clearance of die stamping mold is 20%, 25% of the material plate thickness. (2) Bad alignment of the convex and concave die, including the mold seat and mold guiding components and turret inserts are not accurate enough and other reasons cause bad ...
