Plate Bending Machine
EZHONGis located in the ancient city of Wudu - Ezhou City, Hubei Province. It is one of the heavy forging and shaping equipment enterprises designated by the former First Machinery Department to produce plate bending rolling machines and plate straightening machines. It is a manufacturing company with an independent legal personality established after reform, reorganization and restructuring.
As one of the plate bending machine suppliers, the plate bending machine in chinais forging equipment used to bend metal plates. It is dedicated to the forming and bending work of metal plates. This machine can pre-bend and roll various cylindrical and arc-shaped parts with the help of auxiliary equipment. Rolling of cone-shaped cylinders can be carried out. It is one of the key equipment in the boiler, shipbuilding, petrochemical, metal structure, cement machinery, chemical machinery, machinery manufacturing, and maintenance departments.
As one of the plate rolling machine suppliersand plate rolling machine manufacturers, EZHONG has accumulated rich experience in manufacturing heavy-duty three-roller bending machines, full hydraulic three-roller bending machines, CNC four-roller bending machines, and other bending processing equipment; China's largest bending machine EZW11X-300*3500 hydraulic three-roller bending machine is manufactured by EZHONG. The maximum pressing force of the bending machine is 7800T, which is second to the roll plate bending machinewith a pressing force of 8000T from Switzerland HAEUSLER.
How does a plate rolling machine work?
The purpose of the cnc plate rolling machineis to bend the plates with different characteristics according to the production capacity.
The production process of the cnc plate bending machineis to operate the machine from the control panel (equipped with all control equipment and indicator lights) under the control of the operator.
The working cycle controlled by bending machine factory chinais adjusted by limit switches, position sensors and other display sensors. These adjustments ensure the accuracy of the work and eliminate the possibility of program errors. Through the interface on the control panel, several manual operations can be concentrated into simple guided actions.
The variable center distance hydraulic horizontal three-roller plate bending machine is a machine with medium/large thickness plate pre-bending and rolling products of different shapes.
This model is different from the traditional model, because each of its lower rollers can move independently horizontally to produce any desired pitch, and the upper roller with a motor can move vertically.
The possibility of increasing the distance between the lower rollers determines that the same force and power as multiple pre-bending machines can be used in only one machine. The controlled horizontal movement of the lower roll makes the pre-bending operation very easy. The reduction of the center distance of the lower roller can better drag the steel plate, which facilitates the subsequent bending of products with smaller diameters and thickness, and facilitates the measurement of the curved plate that must be welded.
Increasing the center distance of the lower rollers makes it easier to bend thick plates and increases the rounding ability.
Due to the upper profiled roller operating system, the machine can be used as a traditional press to perform pressing and measure the finished product.
In the same way, very thick cone plates and curved plates can also be produced through different pressing operations.
How to choose the right bending machine system?
Choosing the right steel plate folding machinewill help you to handle your business easily:
First of all, the system must be practical and easy to use. The current CNC bending machine is easy to produce. If the system is complex, it will waste time.
The system must be stable. If something happens to the machine, a big problem will occur after a few days, so how to choose a stable system? You need to check the product history and customer evaluation, and also need to see the production experience of its manufacturer, if there are technical elites.
The material and processing technology of work rolls require quenching and tempering to increase the surface hardness; structural parts need to eliminate stress, and high-precision processing equipment can ensure assembly accuracy; bearings are also crucial.
The maximum working capacity of the three-roll bending machine depends on the four main parameters of the maximum coil thickness (pre-bending thickness), the maximum coil width, the coil material, and the minimum diameter of the coil in the largest specification. These four-parameter variables influence each other in work. The conversion relationship between the equipment, that is, the conversion relationship of the machine's working capacity, is provided to the user in the random manual so that the user can use and select the equipment more reasonably.
How do you use a rolling bend machine?
Machine operation: standard use process.
This machine is a three-roller bend machine with pre-bending and variable center distance. This model is different from the traditional model. Because the two lower rollers can move horizontally at the same time or completely independently, adjust the pitch between the rollers; the upper roller can move up and down. Due to the above characteristics, the rolling bend machine and campus capabilities have been greatly improved, and the coiling thickness has also been greatly increased.
Since the two lower rollers can obtain the same force and processing capacity, increasing the distance between the two lower rollers can greatly improve the machine's board rolling and campus capabilities.
The shortening of the distance between the lower rolls can make it easier to drag the steel plate, and it can form better when rolling small diameter and thick steel plates and is helpful for the measurement of the welded cylinder. Increasing the distance between the lower rollers makes it easier to roll thick steel plates.
When the lower roller moves horizontally, the left and right cylinders of the upper roller cannot be pressurized. Before all the lower rollers move horizontally, it must be ensured that the upper roller is raised to an appropriate height on the line before the lower roller can move; otherwise, it must not move horizontally.
The reverse movement of the upper and lower rollers should be braked first and then reverse operation.
The rebound is more pronounced during cold rolling, and a certain amount of overwinding must be applied. After the required amount of overwinding is reached, it should be rolled back down to this curvature several times. High-strength steel has a large rebound. In order to reduce the rebound, it is best to perform an annealing treatment before the final forming.
After the rolling bending machine workpiece is rolled, the upper roller should be raised to more than 300mm on the line and the upper roller is in a horizontal state before unloading the workpiece.
