1. Segmental Die
The segmental die consists of the main body of the mold and the inserts, which can create an increase or decrease in segmental gaps. The segmental bending is achieved by reducing it forward.
The inserts, whose thickness can be adjusted, are fixed to the main body of the part using bolts. By changing the thickness of the inserts or altering their angles, the segmental gaps can be modified.
2. Specifications:
1) Suitable for a maximum plate thickness of SPCC-2.3t.
2) Segmental gap range: H=1~10mm.
2.1) The segmental gaps in the mold are determined by the assembly of the inserts and the angles of the parts. Regarding the segmental gaps in the mold, it depends on the assembly of the inserts. However, the segmental gaps in the product are equal to those in the mold. How much is the segmental gap in the mold? It is determined by trial bending various products, and there may be variations in the accuracy.
2.2) If the segmental gap H is smaller, the angle θ will increase.
2.3) The inner bending radius R is generally around R2 or below. When the segmental gap H is smaller, the R angle becomes smaller as well.
3) The inserts belong to the third category of accessories, with 2 pieces each of 1.4t, 2.9t, and 4.9t, combined with chamfered parts.
3. Method of installing the calibration die
1) First, install the upper die; then place the lower die on the lower die installation seat and calibrate it using the calibration die.
2) If the segmental gap is small (around H=1~2mm), the mold can also be aligned directly by matching the upper and lower dies.
3) Adjustment method for the calibration scale: (1) When adjusting dimension A, the segmental gap may vary due to different plate thicknesses or bending shapes. It cannot be generalized; this is just a rough adjustment range: A=V/3+0.245t; (2) Measure the vertical distance between points a and b, and the vertical distance between the ends of the mold should be equal.
4) Precautions for using the calibration tool:
a. First, combine chamfered parts and shims according to the height of the segmental gap and install the upper and lower dies. Do not fix the lower die first.
b. The adjustment amount of the calibration tool should be consistent with (0.245Xt) and the corresponding plate thickness. After adjusting to the corresponding scale, tighten all screws.
c. Place the calibration tool symmetrically on the lower die, align it with the upper die, apply pressure of approximately 1TOM or below, fix the lower die, and then remove the tool.
d. The dimension A shown theoretically changes due to the segmental gap and plate thickness. Since this tool automatically sets the segmental gap, adjusting A according to A=0.245t is possible. There are theoretical data as well as data obtained through actual trial bending. It is necessary to achieve the best angle (especially for bending with different plate thicknesses or obtuse angles).
Warning: Do not exceed the specified pressure resistance of the mold. If any part of the mold is found to be damaged, stop using it immediately. The mold should be operated strictly according to the operating procedures.
