Proper selection and setup of a punching die for a CNC angle punching line requires a series of steps to be followed and several factors to be considered.

1. Define punching requirements

First of all, the specific requirements of punching need to be clarified, including the size, shape, precision and number of punched holes.

2. Select the appropriate punching mold

Material of busbar: Select the suitable punching mold according to the material of busbar (angle). Different busbar materials may require different types of punching molds.

Punching size: Make sure the die can punch the required size hole.

Shape Requirements: Select the appropriate die according to the shape of the hole to be punched.

Die Material: High quality material can improve the life and performance of the die.

Precision and Stability: High precision and stability of the mold can ensure the quality of punched holes.

Manufacturer's reputation: choosing the products of famous manufacturers, the quality and after-sales service are more guaranteed.

3. Setting and adjusting the punching mold

Preparation: Clean the working table and punching mold to ensure no debris; fix the punching mold on the punching machine.

Adjust the punching pressure: Adjust the appropriate punching pressure according to the thickness of the punched plate and the size of the holes. Too much punching pressure may lead to deformation of the perforated plate, while too little punching pressure will affect the quality of punching.

Setting the punching program: According to the distance and size of the holes on the punching plate, set the corresponding punching program.

Die clearance: For CNC hydraulic punching machine, the choice of die clearance is crucial. The harder the material and the thicker the material, the larger the selected gap should be. Reasonable clearance values can be determined based on empirical formulas or manufacturers' recommendations.

4. Consider other factors

Cost factor: Consider the cost under the premise of meeting the demand.

Compatibility: Make sure the mold is compatible with the angle punching machine.

After-sales service: understand the after-sales service and technical support provided by the manufacturer.

User evaluation: Refer to the experience and evaluation of other users.

In conclusion, the correct selection and setup of punching molds for angle punching machines requires comprehensive consideration of a number of factors, including punching requirements, mold material, accuracy and stability, cost, compatibility, etc. By following the above steps and considerations, you can ensure that the right punching mold is selected and correctly set up and adjusted to achieve a high quality punching operation.
