Specifications for the use of press brake dies

Turn on the power of the press brake, turn the key switch, press the oil pump to start, and the press brake oil pump starts to rotate. At this time, the machine has not started working.

Stroke adjustment. A test run is required when the press brake die is officially used for bending work. When the upper die of the press brake descends to the bottom, a gap of the plate thickness must be ensured. Otherwise, the die and the machine will be damaged. The stroke adjustment also has electric quick adjustment and manual fine adjustment.

Selection of the notch of the press brake die. Generally, a notch with a width of 8 times the plate thickness should be selected. If you bend a 4mm sheet, you need to choose a notch of about 32.

Check the overlap and firmness of the upper and lower dies of the press brake; check whether each positioning device meets the requirements of the processing. Frequently check the overlap of the upper and lower dies; whether the indication of the pressure gauge meets the regulations.

The sheet must be compacted when bending to prevent the sheet from tilting up and injuring the operator during bending.


When adjusting the sheet die, the power must be cut off and the operation must be stopped.

When changing the opening of the lower die of the variable press brake, no material is allowed to contact the lower die.

It is forbidden to use the press brake die to bend super thick iron plates or quenched steel plates, high-grade alloy steel, square steel and plates that exceed the performance of the sheet press brake to avoid damaging the machine tool.

To turn off the press brake, place wooden blocks on the lower die under the oil cylinders on both sides to lower the upper slide onto the wooden blocks. Exit the control system program first, then cut off the power supply.

Why Choose Lio-nel

Precision Design and Customization

Our press brake toolings are precisely designed through advanced computer-aided design (CAD) technology to ensure that each tooling can meet the specific needs of customers. We also provide customized services to design the most suitable tooling solutions according to the specific requirements and application scenarios of customers to ensure the efficiency and accuracy of the products during use.

Selection of high-quality materials

Our press brake toolings are made of high-performance alloy steel materials to ensure that the toolings have excellent wear resistance and strength. Alloy steel significantly improves the hardness, wear resistance, and fatigue resistance of the material by adding alloy elements. We conduct strict chemical composition and mechanical property tests on the selected materials to ensure that their quality meets or even exceeds international standards, thereby ensuring the stability and reliability of the toolings in long-term and high-intensity use.

Advanced processing technology

In the manufacturing process of our press brake toolings, we use the latest processing technology and advanced process flow, including high-precision CNC machine tool processing, laser cutting, precision wire cutting, etc. These advanced technologies can not only ensure the high precision and complex shape processing of the tooling but also effectively improve processing efficiency and product quality. These technical advantages enable our toolings to provide higher performance and stability in actual use.

Strict tolerance control

Our press brake tooling manufacturing process uses high-precision CNC processing equipment and technology to ensure that the size and shape of each tooling meet precise requirements. We strictly control tolerances during processing to ensure that the toolings can still maintain a high degree of consistency and accuracy during high-pressure bending, thereby improving the quality of the finished product.

Efficient heat treatment process

We use advanced heat treatment processes on the tooling, such as vacuum quenching and tempering, to further improve the hardness and toughness of the material. This not only improves the durability of the tooling but also greatly extends the service life of the tooling, reducing the maintenance and replacement costs of customers during use.

Strict quality control and testing

We implement a comprehensive quality control system, from the entry of raw materials to the delivery of products, every link is strictly inspected and tested. We use advanced testing equipment to ensure that every product shipped meets the high standards of customers.


As a testament to our dedication to quality, our products have successfully passed various certifications and industry assessments. When you choose our products, you are investing in a reliable and proven solution that stands up to the most demanding applications.
