SC bending follower support system is a mechanical system used to support a follower during the bending process, particularly in operations like press brake bending, sheet metal forming, or die bending. The system helps control the movement and positioning of the follower, ensuring that the bending operation is performed accurately and efficiently.
Sheet metal press brake machine is a widely used bending equipment. With the development of science and technology, bending machines have entered CNC. People have higher and higher requirements for bending accuracy, and the functional components of bending machines are becoming more and more diverse. We pay more attention to the development of various functional components with characteristics, and strive to improve the automation of machine tools. The bending follower support system is one of the more complex functional components.
During the bending process, the sheet metal is subjected to a local impact force. If there is no support rack at the bottom of the sheet metal, the impact force on the sheet metal will radiate outward when the sheet metal is bent, causing a large deformation of the sheet metal and affecting the bending quality of the sheet metal.
The motion trajectory of the support plate must be completely consistent with the motion trajectory of the workpiece during the bending process, and the motion speed must be kept consistent so that the sheet metal is always subjected to a supporting force and does not deform.
Except the motion trajectory and speed of the two must be consistent, when bending different thickness sheets, the height of the press brake tool and the opening width of the press brake tool are different, this causes the starting point and the rotation bending fulcrum of the sheet to change when it turns up. All these uncertain factors put forward higher requirements for the motion trajectory, speed control and position adjustment of the follow-up support mechanism.
At present, most factories use manual material support. For ordinary small materials, only one person is needed to operate a bending machine, but when bending large sheet metal, it often takes 4 to 6 people to operate a bending machine. It is extremely labor-intensive, and the instability of manual support can easily cause product quality problems and is not conducive to production control.
When bending plates manually, workers need to lift the plates up every time when bending. This process is very laborious, labor-intensive, and low production efficiency. In addition, the movement trajectory of the lifting cannot track the movement of the plates well, the bending effect is difficult to guarantee. Robots are very good at repetitive work. After the bending path is completed, the robots move according to instructions to achieve automated unmanned operations, which can improve production efficiency.
The robot bending needs to move synchronously with the plate according to the movement of the bending tool, avoid plate deformation and poor bending quality caused by gravity during the bending process. In this process, the bending robot needs to accurately follow the bending feed speed and trajectory of the bending machine in real time, otherwise a very small following error will greatly reduce the bending accuracy and even cause the bending workpiece to deform, affecting the bending quality and efficiency. Therefore, the real-time following technology of robot bending is a key technology.
The bending follower support system is a device that assists the press brake machine in bending large workpieces, turns the sheet material upward, keeps a high degree of consistency with the working speed of the bending machine, and can complete the bending process well, replacing the manual support. The application of this equipment in bending work can not only save manpower, but also ensure the accuracy and quality of the workpiece.
The follower support is an independent auxiliary equipment with a separate CNC system and can be operated independently. In terms of design, the height of the follower support is customized according to the height of the bending machine worktable, which is convenient for lifting and ensuring the height synchronization of the work. In addition, according to the size of the workpiece to be processed, the load-bearing capacity of the follower support can also be customized as needed, striving to maximize the lifting assistance and make the production process easier, faster and more efficient.
The main body of the follow-up support is an independent structure. It can be used with any type of bending machine without changing the internal structure of the bending machine. The base is designed with a roller structure, which can be moved and used flexibly at any time, making processing convenient. The appearance design is even more diversified, and can also be customized according to the color of the bending machine.
The servo bending follower trolley is a semi-automatic tool that assists bending workers in turning over during the bending process. The servo bending follower trolley has no requirements for the bending machine system. The floor-standing follower front support device has an independent control system and can be moved to cooperate with any bending equipment on the production site.
The bending follower support system of CNC press brake is an auxiliary equipment, which is usually used to work with large bending machines to help lift and move workpieces, especially when processing large or heavy metal plates. Its main functions are:
The follow-up support trolley can help lift larger plates and reduce the physical burden of operators, especially when bending large or heavy metal plates.
It can automatically adjust with the bending angle or operation pace of the bending machine to ensure the stability of the position of the plate during the bending process, thereby improving the bending accuracy and reducing errors.
When processing thinner or larger metal plates, the follow-up support trolley can prevent the plate from deforming due to weight sagging and ensure the final bending effect.
The follow-up support trolley can be linked with the bending machine to automatically adjust the height and position, reduce manual intervention, and improve production efficiency.
This equipment is usually suitable for large-scale sheet metal processing, especially when bending long plates, thick plates or workpieces that are difficult to operate, which can significantly improve work efficiency and processing quality.
The structure of the bending machine follow-up support trolley usually consists of several key parts that work together to support and move metal sheets. Its main structures include:
The support platform is a flat surface that supports the workpiece, usually made of solid metal material and has sufficient strength to support heavier plates. The surface of the platform is usually smooth or has a roller design so that the plate can slide freely on it.
The support platform is often equipped with moving balls or rollers to reduce friction and allow the plate to move smoothly. Depending on the weight and size of the workpiece, the rollers can be static or dynamic (rotatable). Sometimes they are also designed as rollers with locking functions to fix the position of the plate.
The bending follower trolley is equipped with a lifting system, usually a hydraulic or electric system. The system can automatically adjust the height of the support platform according to the action of the bending machine, so that it keeps in sync with the workbench of the bending machine to prevent the workpiece from displacement or deformation during the bending process.
The linkage control system of the bending follow-up trolley works synchronously with the bending machine. This system is usually implemented through sensors, controllers or PLC (Programmable Logic Controller), which enables the material support trolley to sense the movement and angle changes of the bending machine and make corresponding adjustments to ensure the smooth movement and positioning of the workpiece.
The bottom of the follwer trolley is usually equipped with slides, guides or wheels to enable it to move forward and backward. The moving device can be manually operated or automatically controlled, and the position is adjusted by the control system or the operator's instructions to facilitate the free movement of the plate around the bending machine.
The main structural frame of the follow-up material support trolley is used to support the platform and lifting device, and is usually made of steel or other high-strength materials to ensure stability and durability. The structural frame is usually designed to be adjustable to accommodate different sizes of bending machines and plates.
In order to ensure safe operation, the trolley is usually equipped with safety devices such as limit switches and emergency stop buttons to prevent accidents during lifting or moving.
Through these structures, the follow-up material support trolley of the bending machine can automatically adjust the lifting position to keep the workpiece synchronized with the bending machine, thereby achieving efficient and accurate plate bending operations.
1) It can be equipped with all brands and models of bending machines (up-moving electro-hydraulic servo bending machines, lower-moving torsion shaft bending machines, ordinary bending machines, full-servo electric bending machines).
2) No need to modify the bending machine, only need to install a displacement sensor on the slider of the bending machine, connect to the three-phase 380V power supply of the workshop, and then use it to avoid the failure caused by modifying the bending machine box and taking the signal of the bending machine It also avoids the work-related accident of the bending machine falling off the knife and pressing the operator's hand due to the follower interfering with the signal of the bending machine.
3) Follower: independent movable trolley, standard table size 650mm*1400mm, minimum table height 950mm, length direction can be extended, lifting and bending workpiece angle 30°~ 90°.no programming is required for standard bending, special bending ( Bending and pressing dead edges with composite molds) only need to select the processing technology mode to use.
4) Displacement sensor: The follower senses the position and speed of the bending machine die movement through the displacement sensor, and sends a signal to the control system of the follower in real time to achieve complete synchronization with the bending machine.
5) Independent power supply for the follower.
6) Hydraulic, pneumatic and electric lifting rotary table: when bending larger parts, it is convenient for parts to turn around (option).
The bending follower support system is an essential component in various bending operations, providing support, guidance and load distribution to ensure accurate and consistent results. The role of the SC bending follow-up support in maintaining accuracy, reducing deformation and improving overall efficiency cannot be underestimated!
