maintenance of stamping dies for press machines

The maintenance work of stamping dies is divided into two levels. The primary maintenance includes maintenance during mold installation, maintenance during production, and maintenance after production. Secondary maintenance is the maintenance of stamping die parts. Good maintenance ensures stamping dies work better and last longer. So, what are the main points of these two levels of maintenance?

First-level maintenance of stamping dies

1. Maintenance during mold installation

Before installing the mold, it is necessary to clean the upper and lower surfaces of the mold. So that the mold installation surface and the press table surface are not crushed. And the parallelism of the upper and lower installation surfaces of the mold in production can be better. After the mold is installed, open the mold, and wipe it carefully. Wipe its surface clean to ensure the quality of the parts. In addition, the parts of the mold need to be lubricated. The parts of the mold need to be checked. The safety parts need more attention, such as: safety side pins, Security screws, side guards, punched waste channels, etc.

2. Maintenance in production

In the production process, it is necessary to regularly oil the corresponding parts of the mold. Such as: the blanking ring, fillet of the drawing die, the edge part of the trimming die, etc. Also regularly clean the small holes for dropping wastes of trimming and punching.

3. Maintenance after production

After the production is over, the mold should be carefully inspected. The mold should be wiped to ensure the cleanliness of the mold. The waste in the mold should be cleaned up in time to ensure that there is no waste in the waste box. Register the working performance and status after use.

Secondary-level maintenance of stamping dies

The maintenance work needs to be carried out by the mold maintenance personnel, and the maintenance situation shall be recorded. Next, we will introduce the requirements and methods of secondary maintenance of different components:

1. Drawing mold: punch and die

The main problems of male and female dies are fluffing and dimples on the forming surface. During maintenance, it is necessary to polish the rounded and brushed parts of the mold. If there is a pressure pit, it needs to be repaired first.

2. Guide parts (guidepost, guide sleeve and guide plate, etc.)

During the working period, there may be scratches and other phenomena in the mold, which are caused by the dirty lubricating oil and the deviation of the guide gap. When there is a pull mark on the guide part, it is maintained by pushing it with a whetstone and then polishing it.

3. Trimming edge

In the process of using the mold, the edge of the blade may be chipped, and the edge is collapsed, which requires us to regularly repair the damaged edge of the mold.

4. Springs and other elastic parts

In the process of use, the spring is one of the easily damaged parts of the mold. It is usually broken and deformed. We need to replace it in time. However, during the replacement process, we need to pay attention to the specification and model of the spring. Color, outer diameter, and length, it can be replaced only when these three parameters are the same.

5. Punch and punch sleeve

On the die, most of the punches and punch sleeves used are standard parts, which are prone to breakage when the die is used. The bending and gnawing can be replaced by parts of the same specification. The main parameters are the size of the working part, installation part size, length, etc.

6. Fastening parts

Check whether the fastening parts are loose or damaged. If damaged, they need to be replaced in time.

The above are the main points of the secondary maintenance of the stamping die shared by the editor. Pay attention to these in the use and maintenance, so that the stamping die can work better. World Machinery is a professional supplier of stamping power press machines in China. The quality of stamping parts will be fine, based on high quality press machines and stamping dies. Good maintenance of dies are as same importance as the maintenance of press machines.
