Sheet follower of the press brake is a widely used bending equipment. With the development of technology, press brakes have entered the era of numerical control. People’s requirements for bending accuracy are getting higher and higher, and the functional components of bending machines are getting richer and more diverse. Powerful companies are paying more and more attention to the development of various functional components with special features and striving to improve the automation of machine tools. One of the more complex functional components is the accompanying pallet mechanism.
At present, most factories are manually palletized and only one person is needed to operate a press brake for small materials, but when it comes to large sheet metal, it often takes four to six people to operate a press brake. It is extremely labor-intensive, and the instability of the manual pallet is likely to cause product quality problems and is not conducive to production control.
There are also press brake manufacturers with their own pallets, but they are often unable to synchronize their operation with the sheet material. In the bending process, there is often a period of time when the plate material and the pallets do not fit closely together, resulting in jittering of the material plate during the bending process, poor stability, and easy damage;
Secondly, when bending different plate materials, in order to make the pallets and the plate material fit closely together, it is often necessary to make appropriate adjustments to the position of the pallets, but nowadays the pallets are driven by chains of oil cylinders, and the distance of adjustment cannot be judged, resulting in lower adjustment accuracy. However, the current pallets are driven by chains of oil cylinders and the adjustment distance cannot be judged, resulting in lower adjustment accuracy, and the whole adjustment structure is complex and impractical.
A sheet follower is a device used in press brake machines to ensure that the sheet metal being bent maintains its position and does not move during the bending process. The sheet follower is usually a movable plate that follows the movement of the bending punch and applies pressure to the sheet metal that is bent, holding it in place against the back gauge.
By using a sheet follower, the press brake operator can ensure accurate bending angles and prevent the sheet metal from shifting or sliding during the bending process. This results in higher-quality bent parts and reduced material waste.
Sheet followers are available in various designs and configurations to suit different types of press brakes and sheet metal bending applications. Some sheet followers are manually adjusted while others are automated and controlled by the press brake’s CNC system.
Application Characteristics of The Servo Bending Sheet Follower
1. High Compatibility
Servo bending with the car is a semi-automatic tool to assist bending workers in the bending process to do upward turning action, servo bending with the car is different from the market with the device, servo bending with the car on the bending machine system, pressure spindle are no requirements, with the car has an independent control system, can be moved to the production site with anyone bending equipment, in the second installation of the bending machine interface with the car parameters debugging, the next time you connect only manually adjust the car.
The next time it is connected, it is only necessary to manually adjust the height of the car, and call out the current bending machine with the parameters, you can use. There is no need to purchase a bending machine with a follower mechanism in order to improve the process, reducing factory production investment.
The standard pallet size of the servo bending follower is 900mm x 600mm, with a brushboard as the main part, which can avoid scratches caused by the sheet metal bending process, and the pallet width can be expanded by adding profile support according to the requirements of the processed workpiece and can also be individually modified according to customer requirements.
Rotating pallets can be added to reduce the difficulty of rotating large-size workpieces in the direction of bending, and 1 to 2 operators can easily and steadily complete the bending process of large-size panels.
Universal bearings can be added around the pallet to reduce the difficulty of loading and unloading large-size workpieces.
3. High Stability
The servo bending sheet follower car adopts a single-axis mechanical linkage, which simplifies the control procedure on the one hand and improves the stability of the machine on the other. At the same time, the simple operation and anti-dumbing settings allow the operator to get up to speed quickly.
The servo bending trolley and the bending and forming machine can be combined to form a semi-automatic machine, which saves labor and allows for fast and flexible prototyping and mass production, with good economic benefits.
How to Choose A Sheet Follower
1. The factory already has a press brake, at this time, as long as the accompanying move before the material trolley, in the existing press brake add a set of magnetic scales to get the positioning signal on the line, simple and easy to operate.
Bending with the car is a semi-automatic tool to assist bending workers in the bending process to do upward turning action, servo bending with the car and the market with the device is different, servo bending with the car on the bending machine system, pressure spindle are no requirements, with the car has an independent control system, can move with the production site with any bending equipment, in the first installation of the press brake interface and with the car parameters debugging, the next connection only need to manually adjust the car. The next time you connect only need to manually adjust the height of the car and call out the current press brake with the parameters, you can use.
2. Newly bought presse plieuse, press brake equipped with a follow-me mechanism, press brake follow-me before the rest of the material device is fixed in the bending machine, easy and fast operation, high processing accuracy. Reduce work intensity and improve efficiency. CNC press brake front bracket device can be made according to customer requirements optional, to facilitate high-quality bending processing.
Servo bending with press brake trolley and bending forming machine can be quickly composed of semi-automatic, saving labor at the same time can be fast and flexible proofing and mass production, with good economic benefits.
Classification of Sheet Follower
There are different types of sheet followers that can be used with press brakes, including:
- Pneumatic sheet followers: These are operated using compressed air and can be adjusted for different sheet thicknesses.
- Hydraulic sheet followers: These use hydraulic pressure to adjust the follower position and are ideal for use with heavier sheets.
- Roller sheet followers: These use rollers to support the sheet metal and help guide it through the bending process.
- Magnetic sheet followers: These use magnets to hold the sheet metal in place during bending.
The type of sheet follower that is most appropriate for a given application will depend on factors such as the thickness of the material being bent, the size of the press brake being used, and the desired degree of precision and control.
