Classification of turret punch dies

Let’s take the Amada puncture as an example:

AMADA CNC punching molds can be divided into two categories: original molds (metal return plate) (Fig. 1) and domestic molds (rubber return plate) (Fig. 2).

Based on the shape of the mold, they are classified as round mold, waist round mold, rectangular mold, square mold, special shape mold, forming mold (specimen punch, bump, recess, rotating hole, shutter and crimping die) .

The size of the matrix determines the corresponding stations, which are divided as follows:

Station X

Generally round mold (φ1.6 ~ φ12.7) and front sample die.

Corresponding to 10 machine tool stations;

Station B

This includes round matrices (φ13 φ27), square matrices (SQ4 SQ16), partial rectangular dies, partial waist round dies, and special-shaped partial dies (such as keyhole, cross, trapezoidal, hexagonal, and single-D dies). In addition, there are forming dies (reverse sample punch, bump, countersink, hole turning die, etc.) that correspond to the 16 stations of the machine tool.

Station C

Revised version:

Available die types include round dies (φ30~φ37), square dies (SQ20), partial rectangular dies, partial waist round dies and special-shaped partial dies (double ear dies). These correspond to the 6 stations of the machine tool.

D Station

This product includes round dies (φ40-φ50), square dies (SQ35), partial rectangular dies and partial waist round dies. These are designed to correspond to the 4 stations of a machine tool.

Station E F

The main components of the machine are the milling cutter (RE60x4, RE60x5), the square die (SQ50) and the special-shaped die (nine-hole die). These correspond to the two stations of the machine tool.

S tation G , H

Cutter (RE80x6), special shaped die (shutter).

Corresponding to 2 machine tool stations;

Station I

Indexing rotation station, is used to install the mold to be rotated.

Corresponds to 4 machine tool stations.

Lower matrix selection

The general rule is to select the bottom die gap according to the material thickness of the workpiece to be processed, as shown in Table 1.

Table 1 Die Bottom Gap Selection

Material thickness (mm) 0.5-1.0 1.2 1.5 2.0-3.0 4.0
Clearance (mm) 0.1-0.15 0.15-0.2 0.3-0.40 0.4-0.6 0.6-0.8

It should be noted that normally the lower die specified for the upper die has a gap of only 0.1mm to 0.4mm.

However, when processing boards thicker than 3 mm, flexibility in selection is required. For example, when working with a 4mm copper plate, the maximum bottom die gap of φ6.5 is only 0.4mm. In this case, a lower die of φ7.1 (0.15 mm) can be used.

Installation of lower die

Open the turret cover → rotate the machine tool to the station where the lower die will be installed → remove the lower die base with the specified tool → place the lower die in the corresponding empty station → check the height (the height of the lower die it may be 1mm ~ 2mm higher than the die base. If the height of the die itself is not enough, add shims to adjust it to reach the standard height) → tighten the screws → install the lower die base onto the die base. tower → fix the lower die. base on the tower with the specified tool → installation of the lower die is complete.

The lower die installation sequence is shown in Figure 3.
