Forming and Bending Machine Molds Display
Blank (upper mold) selection mainly coordinates with the workpiece shape during processing. The mold usually uses a V=6t (t being the material thickness) mold. Factors influencing the process include material type, upper mold arc radius, material thickness, lower mold strength, and lower mold mold size. Basic principles of bending processing sequence: 1) Bend from inside to outside; 2) From smaller to larger bending mold; 3) Bend special shapes first, then general shapes; 4) The formation in the previous process will not affect or interfere with the subsequent process.
For structures with an annual production volume exceeding 5,000 pieces and relatively small component dimensions (usually 300x300mm), the use of bending machine forming molds can be considered. Common bending molds and CNC bending machine mold specifications, to extend the mold's lifespan, component design should be as rounded as possible. If the bending height is too small, using bending molds is also不利于 shaping. CNC bending machine molds, the bending mold height is L3t (including wall thickness).
Introduction to Reasons for Aluminum Plate Breakage in Bending Machine Processing
During daily processing, aluminum plate fractures often occur. What causes this situation? Custom CNC bending machine molds and forming bending machine mold manufacturers have analyzed the possible causes, which can generally be divided into several factors: the hardness and thickness of the aluminum plate, the size of the bending angle, and the pattern of the aluminum plate. Below is a detailed introduction to the possible causes.
1. Aluminum plate grain direction
The bending direction must be perpendicular to the grain of the aluminum sheet, not parallel.
2. Aluminum plate hardness
The aluminum plate is too hard and prone to cracking. This necessitates careful selection of the aluminum material, primarily focusing on the brand and condition of the aluminum bending die material. Generally, Series 1, 3, and 5 are commonly used; Series 6 and 7 are too hard and must be annealed to the O state before bending.
3. Aluminum Sheet Thickness
Thick aluminum sheets are not ideal for bending; it's common sense that the thinner the aluminum sheet, the better, so try to use aluminum sheets with thinner bending molds.
4. Bend Radius Size
The larger the radius of the bend, the higher the success rate, so adjust the bending mold to increase the radius of the bend as much as possible.
When bending various materials, you can choose a bending machine mold. The operation of this equipment is relatively simple, and the purpose of use can be achieved through a straightforward operational process. The processing range of the mold is also quite extensive. Both metal and non-metal materials can be processed directly through this mold. Moreover, it can avoid many unnecessary operational items during the processing and effectively reduce the application costs. In recent years, the application of this mold has gained increasing attention.
