The bending machine mold is a tool used by the bending machine to shape and process sheet materials. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the shape of the object through changes in the physical state of the molded material. A tool used to turn blanks into parts of specific shapes and sizes under the pressure of a bending machine.
Bending machine molds can be divided into two major categories in structure: upper mold and lower mold.
The materials of bending machine molds generally include 42CrMo, T80, 9Crsi, H13 (suitable for shearing machines, the material is harder), gcr15
p.s. Prices are based on specific product scale.

The Process of production
Instructions for use
1. Turn on the power of the bending machine, turn the key switch, and press the oil pump to start. The bending machine oil pump starts to rotate. At this time, the machine has not started working.
2. Stroke adjustment. A test run is required when the bending work is officially started with the bending machine mold. There must be a gap of plate thickness when the upper mold of the bending machine moves down to the bottom. Otherwise it will cause damage to the mold and machine. The stroke adjustment also includes electric quick adjustment and manual fine adjustment.
3. When selecting the notch of the bending machine mold, generally choose a notch with a width that is 8 times the thickness of the plate. If you want to bend a 4mm sheet, you need to choose a notch of about 32mm.
4. Check the overlap and solidity of the upper and lower dies of the bending machine; check whether each positioning device meets the requirements for processing. Frequently check the overlap of the upper and lower molds; whether the indication of the pressure gauge complies with regulations.
5. The sheet must be compacted when bending to prevent the sheet from lifting up during bending and injuring the operator.
6. When adjusting the sheet metal die, the power supply must be cut off and the operation must be stopped.
7. When changing the opening of the lower mold of the variable bending machine, no material is allowed to come into contact with the lower mold.
8. It is prohibited to use the bending machine mold to bend ultra-thick iron plates or quenched steel plates, high-grade alloy steel, square steel and sheets that exceed the performance of the sheet metal bending machine to avoid damaging the machine tool.
9. Close the bending machine, place wooden blocks on the lower mold under the oil cylinders on both sides, and lower the upper slide plate onto the wooden blocks. Exit the control system program first, and then cut off the power supply.
Installation and adjustments
When installing the bending machine mold, be sure to check the status of the equipment, and then follow the steps to install and debug. Pay attention to personal safety during debugging.
When installing the bending machine mold, you must first understand the machine performance, open the bending machine, patiently adjust and check to see if the machine has dust and iron debris from previous use. To prevent unnecessary trouble for later use.
First check whether the ratio of the thickness of the bending machine mold to the upper and lower modules is normal. The general slider needs to be controlled at the switch point of the stroke line. This must be paid attention to, otherwise the mold will not be used normally, but some people still often make mistakes.
After adjusting the slider stroke standard, the next step is to adjust the upper limit point of the module. Generally speaking, when the module reaches the highest point, the module and switch must be set properly. In this way, the stop position of the module can be flowed out. Through some of the above operations, the production efficiency can be greatly increased. During this process, the module also needs to be slowed down. Because when the module moves down to the bottom dead center, it must decelerate the module, thus protecting the machine and the mold.
The last step is to adjust the gap between the bending machine molds. First measure the gap between the upper module and the lower module. The reasonable gap needs to be determined according to the plate being folded.
Adjusting the bending angle is also the most important step. The selection of the angle must be related to the product requirements. Generally speaking, when bending a 90° mold, the angle must be set. The middle angle must be greater than the angles on both sides. Sometimes it may be tight. You can adjust it by adjusting the bending angle. Process the screws on the machine. After adjustment, do not make any further modifications unless the product needs change. Then when bending, use the pressure gauge to calculate the accurate pressure number and adjust the pressure to avoid causing the mold to collapse.
We can customize the press brake dies that you want if you give us the design drawings. It doesn't matter if you don't have any design drawings, we can draw some based on your requirement.
In order to facilitate the bending of any length, the standard split mold of the mold has two options: A and B
A:
Upper mold 100(Left ear).10.15.20.40.50.200.300.100(right ear)=832mm
Lower mold 10.15.20.40.50.100.200.400=835mm
B:
Upper mold 100(Left ear).10.15.20.40.50.165.300.100(right ear)=800mm
Mold library
2 kinds of ways:
`LCL: covered with plastic film, packed in wooden case.` FCL: covered by plastic film, packed by container.
`Before packaging, the mold will be strictly tested to ensure its stability and high precision.
`After testing, the mold will be packed in a plastic fabric and the mold will be placed securely inside the container.
`Each mold is first packed with plastic film and then placed into a wooden box with foam padding.
`We charge machines for heavy truck cargo at terminal charging ports. For docking, we pack the goods in containers and ship them abroad.
