How to Create a New Punch in ESA S640

Creating a new punch is the core of the ESA S640 setup process, and it can be done by either designing a custom punch from scratch or modifying pre-set punch types to fit your needs. Follow the step-by-step instructions below to complete the process accurately.

Step 1: Initiate New Punch Creation

1. Open the Tool Library: Press the designated tool library button to bring up the punch list on the interface.

2. Switch to the Punch Section: If the die list is displayed by default, press the tool library button again to toggle to the punch list.

3. Select a Punch Configuration Method: Choose your preferred way to create a punch—either design a fully custom punch from scratch or use one of the four pre-set punch types with fixed default dimensions (the pre-sets can be adjusted to match your specific operational requirements).

> Important Note: Accurate punch drawings are essential for the system’s

workpiece anti-collision checks, and precise punch dimensions are the basis for calculating bending depth. If designing a custom punch from scratch is challenging, select a pre-set type and adjust its parameters to closely match the actual punch shape using the system’s predefined data fields.

4. Select the Corresponding Button:

￮ Press [New Drawing] to design a fully custom punch.

￮ Press [New Type 1]/[New Type 2]/[New Type 3] to use the respective standard pre-set punches.

￮ Press [New Type 4] to access the pre-set round punch.

5. Input Punch Specifications: After selecting a punch type, a parameter entry window will pop up. Enter key dimensional data such as the punch’s total height and working height, ensuring all values align with your fabrication needs.

6. Enter the Drawing Page: Once the basic dimensions are entered, press [Ok] to access the punch drawing page. The page layout will vary based on the punch type selected. Finalize the punch design here to ensure it meets the requirements for the system’s anti-collision checks and bending depth calculations—both critical for operational safety and machining accuracy.

Following these steps carefully ensures your new punch setup is precise and tailored to your specific metalworking operations.

Step 2: Draw the Punch Geometry

After entering the basic punch parameters, the next step is to draw the precise punch geometry using the ESA S640’s integrated drawing tool. This step creates an accurate digital representation of the punch and prevents machining errors caused by mismatched tool geometry. The drawing function is accessed via the system’s dedicated drawing module, with additional details available in the official ESA S640 user manual.

The drawing interface consists of a left-side drawing workspace and four right-side data entry panes, which are used to input polar coordinates, Cartesian coordinates, vertex points, and arc drawing parameters respectively.

Key Drawing Rules & Vertex Entry

Adhere to the following conventions to ensure the accuracy of your punch drawing:

1. Draw Counterclockwise: Always draw the punch geometry in a counterclockwise direction, and keep in mind that the machine’s back-gauges are located on the right side of the punch.

2. Define the Punch Tip (Critical Step): The punch tip is the most important part of the drawing. Start by entering the tip length “lp”, then complete the following steps:

￮ Enter and confirm the tip angle and chamfer dimensions (if required).

￮ Input the tip radius (in the R data field) and press [Ok].

￮ Enter the punch load (maximum tons per meter) and confirm the value. This sequence will draw the punch tip, and the system will apply a default length for the remaining punch sections for further editing.

Detailed Drawing Instructions

Using a standard punch as an example, follow these steps when working in the “lp” data field:

• Input Tip Data Sequentially: Enter the tip’s length and angle values one by one in the designated fields.

• Use the Arc Function for Curves: Press the [Arc] key to create smooth curved sections on the punch; enter the corresponding length and depth values for the arc to generate the shape.
