Selection of bending machine press brake toolss:
Selection of press brake toolss:
1. Determine the required pressure range and working material thickness.
2. Select the press brake tools shape according to the required bending angle and bending radius.
Adjust the press brake tools:
Before installing the press brake tools, the press brake tools needs to be adjusted:
- Adjust the pressing force of the press brake tools so that it fits well with the work piece.
- Adjust the bending angle and bending radius of the press brake tools to meet the requirements of the work piece.
Installation of the press brake tools:
- Firstly, insert the press brake tools base on the table according to the positioning pins.
- The movable press brake tools is then fitted in the press brake tools base.
- Finally, the seat frame of the top press brake tools (position of the theoretical bending line) is fitted to complete the installation of the press brake tools.
Security matters:
- Before installing the press brake tools, switch off the power and wait for the machine to come to a standstill.
- Installation requires attention to the support force to ensure that the installation is stable.
- Strictly follow the operation manual to prevent emergencies.
Use the press brake tools:
After the press brake tools has been installed, bending experiments need to be carried out to determine whether the press brake tools and the machine are stable and whether the press brake tools meets the requirements of the workpiece.
Summary:
Correct installation of the bending machine press brake tools is the key to ensure the normal operation of the machine. Therefore, when installing the press brake tools, you need to take the adjustment and installation steps seriously to ensure that it is installed correctly to ensure operational safety and productivity.
Code of practice for the safe operation of press brake tools:
- The operator must be familiar with the general structure and performance of the equipment.
- The parts of the bending machine to be lubricated should be refuelled regularly.
- Before bending idle run to check the equipment is not abnormal, before operation.
- It is prohibited to operate the bending machine while the bending dies are installed.
- Correctly select the bending press brake tools, the upper and lower die fastening position should be correct, the installation of the upper and lower die operation to prevent trauma.
- It is not allowed to pile up debris and tools between the upper and lower press brake tools when bending.
- When operating with more than one person, identify the main operator and have the main operator control the use of the foots witch, and no other person should use it.
- When bending large work pieces, it is important to prevent injuries to the uplifted surface of the sheet.
- Abnormalities in the bending machine immediately cut off the power supply, stop the operation, and notify the relevant personnel to solve the problem in a timely manner.
- When finished, stop the upper tool to the lower dead centre, cut off the power supply and clean up the work site.
Installation adjustments:
1, the adjustment of the machine, before the installation, first of all, to adjust the machine performance, this process must be patient and serious, to see if the machine is not dust and used iron debris, etc., to carry out the necessary clean-up, in order to reduce the trouble later.
2, the slider stroke adjustment, pay attention to check the thickness of the press brake tools and pay attention to check the ratio of the upper and lower modules is not normal, normally the module should be controlled in the travel line switch point, must pay attention to.
3, the adjustment of the travel module, that is, for the upper limit of the module to adjust the point, in the module up to the highest place, set the switch, and reserved for the slider to stay in place, at the same time in the downstream should also be decelerating the module, better protection of the machine and press brake tools .
4, the adjustment of the gap, mainly by first measuring the distance between the upper module and the lower module, the specific gap setting is based on the folded sheet.
5, the angle of adjustment, this angle of adjustment with the product has a certain relationship, generally speaking, fold 90 ° press brake tools, then the middle angle must be greater than the angle of the two sides, then it can be loosened or tightened according to the adjusting screws, in the bending, you can through the pressure gauge to adjust the pressure, to avoid the press brake tools collapse edge.
Bending machine press brake tools material type:
1, the upper and lower press brake tools material is generally used 7TT8, and then some better 42CrMo material, it requires the main high strength \ high toughness and good abrasion resistance, the selection of cold work press brake tools steel, quenching hardness to reach the upper die 48 ° -45 °, the lower die 42 ° -45 °, the upper die to be more than the lower die hard.
2, carbon steel: carbon steel has excellent strength and toughness, usually can meet the requirements of ordinary bending processing, and the price is relatively low, is a commonly used materials. Alloy steel: compared with carbon steel, alloy steel has higher wear resistance and heat resistance, suitable for processing higher strength or higher temperature plate.
3, stamping CNC CNC bending machine press brake toolss used in the material belongs to the cold processing CNC bending machine press brake tools steel, a wide range of uses, a wide range of types. The main performance requirements are strength, toughness, wear resistance.
4, by T10 (carbon tool steel), Cr5Mo (chromium-molybdenum alloy steel for high-temperature environments), 9CrSi (low alloy tool steel) made of shear blades, suitable for cutting ordinary A3, ordinary low-carbon cold-rolled sheet and scrap; in addition, made of 9CrSi (low alloy tool steel) shear blades, is also suitable for shearing the harder thin steel plate.
5, bending machine press brake tools material is generally T8 or T10, better 42CrMo, the main requirements of high strength, high toughness, good wear resistance. Selection of cold work press brake tools steel. cr12MoV is a very good material. The use of performance can meet, good process performance, the price will be high.
6, commonly used bending machine on the press brake tools material Ordinary carbon steel: ordinary carbon steel is a common bending machine on the press brake tools material. It has a low cost, moderate hardness, can be applied to most of the light, medium-thickness sheet metal processing. Alloy steel: alloy steel compared to ordinary carbon steel, higher hardness, better wear resistance.
