Punching Machines Explanation

We are a professional punch press manufacturer with over 10 years of industry experience. Today, we would like to introduce the steps of stamping press mold installation and debugging to you:

Mechanical press is a commonly used processing equipment in the manufacturing industry, and the installation and debugging of the mold directly affects the quality and productivity of the stamped parts. Correct installation and debugging can not only ensure the processing accuracy, but also extend the service life of the mold and press. The following are the basic steps and precautions for mold installation and debugging.

1、Preparation

(1)Check the equipment and mold

Before installing the mold, you need to make sure the punch press is in the stop state and turn off the power. Check whether the key parts of the press, such as table, slider and guideway, are clean and have no wear or damage. At the same time, check whether the model and size of the mold match with the punch press, and make sure that the mold is free from cracks, deformation and other defects.

(2)Preparation of tools and auxiliary equipment

Installation of the mold usually requires the use of wrenches, screwdrivers, jacks, pads, vernier calipers and other tools. If necessary, lifting equipment (such as forklifts or trucks) can be used to assist in the handling of large molds to ensure operational safety.

2、Mold installation

(1)Adjust the stroke of the press

According to the height of the mold, adjust the stroke of the press slider to ensure that the slider can close with the mold correctly at the lower dead center. The position of the slider can be adjusted manually or in pointing mode to avoid interference when the mold is installed.

(3)Installation of the lower mold

Place the lower mold on the working table and make sure its corresponding position with the upper mold is accurate. Observe the match between the upper and lower molds by trying to close the mold (manual coiling).

When fixing the lower mold, tighten the bolts symmetrically from the center to all sides to avoid the mold shifting due to uneven force.

3、Mold debugging

(1)Adjust the closing height

The closing height (i.e. the position of the slide when the mold is closed) directly affects the stamping effect. Gradually adjust the closing height through the adjusting device of the press to ensure that the upper and lower molds are neither too tight (which may damage the molds) nor too loose (which may affect the molding accuracy) when they are closed.

(2)Test run

Test run in manual or single press mode, observe whether the movement of the mold is smooth and whether there is any abnormal noise or vibration.

Check whether the size and burrs of the stamped parts meet the requirements. If deviation occurs, fine-tune the mold position or closing height.

(3)Checking safety devices

Ensure that the safety devices such as the grating and emergency stop button of the punch press work properly to avoid accidents during commissioning.

4、Cautions

(1)Operation specification

It is strictly prohibited to adjust the mold while the press is running.

Debugging needs to be operated by a special person, avoiding simultaneous intervention by many people.

(2)Lubrication and maintenance

After the installation is completed, it is necessary to add appropriate amount of lubricant to the guiding parts of the mold (such as guide pillar and guide sleeve) to reduce wear and tear.

(3) Record parameters

After the debugging is completed, record the key parameters such as closing height, stamping speed, etc., for easy reference in subsequent production or replacement of the mold.

Abnormal noise: stop the machine immediately to check and exclude loose molds or press failure.

The installation and commissioning of the mold is an important part of stamping production, need to strictly follow the steps of operation, pay attention to details and safety. Standardized installation and debugging can not only improve production efficiency, but also reduce equipment loss and ensure stable product quality. In actual operation, the operator should combine the equipment with the specific conditions of the mold flexible adjustment, accumulate experience to enhance proficiency.
