What is the impact of bending molds on machining accuracy?

The influence of bending mold on the machining accuracy of bend sheet metal is mainly reflected in the following aspects:

1.Design of mold fillet radius

• Impact angle accuracy: If mold fillet radius is too small, it will produce cracks in the plate at the crease. If the radius is too large, the theoretical bending angle may change (for example, the actual bending angle of a 90° mould may become 88 °-89 °).
• Rebound compensation: The mold needs to design a pre-bending angle (e.g. add 2-3° to compensate for rebound of aluminum plates) based on the ductility of the material.

2.Matching mold gaps

• Too small gap: Causing too much friction between the plate and mold, causing scratches or surface indentations, affecting the appearance quality.
• Excessive clearance: Results in plate sliding bias, resulting in bending angle deviation (error up to ± 1°-2°).

3.Mold surface roughness

• High precision mold: Surface roughness  Ra≤ 0.8μm, can reduce plate scratching and improve surface smoothness.
• Rough: When Ra> 1.6μm, it is easy to cause metal debris to adhere to the surface of the plate, affecting subsequent spraying or welding processes.

4.Mold materials and heat treatment

• Mold hardness: Cr12MoV mold steel (HRC58-62) has a service life more than three times that of normal 45# mold steel and is not easily deformed after long use.
• Heat treatment defects: Mold quenching inhomogeneity will accelerate local wear and affect bending consistency.

5.Mould wear and maintenance

• Wear threshold: When the mold blade wears more than 0.1mm, the stability of the bending angle decreases significantly (e.g. from ±0.5° to ±2°).
• Maintenance cycle: It is recommended that mold size be checked every 5,000 processing cycles and repair or replaced in a timely manner.

6.Match of mold thickness and plate thickness

• Thin plate mold (≤ 1mm): Alloy inserts are required to prevent breakage of the mold due to excessive punching force.
• Thick plate mold ≥ 3mm: It is necessary to add a gasket design to the bottom of the mold to disperse pressure and avoid plate layering.

How to choose the material thickness of sheet metal parts?

The selection of sheet metal part material thickness requires comprehensive consideration of function requirements, process limitations and economy. Sheet metal gauge chart is the core tool to guide selection. Here are the key steps and highlights:

1.Clarify application scenarios and load requirements

• Static loads (such as brackets and shells): The yield strength of a sheet metal gauge chart, select the minimum thickness that can withstand the expected load.
• Dynamic load (e.g. car chassis): Fatigue strength needs to be calculated, usually 20% to 30% more than static load.
• For example, if the electrical casing is subjected to a concentrated load of 50kg, according to the gauge chart, SPC steel 1.5mm thick meets the bending strength requirements.

2.Matching thickness range of manufacturing process

The sheet metal gauge chart will indicate the recommended thickness range for different processes, such as 0.8mm-3mm for aluminum sheet metal (1060) bending.

3.Balance cost and material utilization

• Thin plates (≤1mm): Low cost but easily deformed, suitable for large quantity of load bearing components (e.g. computer chassis).
• Thick plates (≥4mm): Material costs and processing difficulty are high and require optimal selection through gauge chart (e.g. replacement of 4mm plates with 3mm plates and reinforcement).
• Economic Thickness: Refer to industry-standard sheet metal specifications, such as the commonly used 1.0mm-1.5mm galvanized sheet metal in the automotive industry, to balance strength and cost.

4.Consider the impact of connectivity technology

• Welding: When plate thickness difference is more than 30%, step welding or groove treatment is required (e.g. cross-welding between 2mm and 1.5mm plates).
• Riveting: The total thickness of the plate ≤3 times the riveting diameter (e.g. M5 riveting for aluminum plates ≤1.5mm in thickness).
