What is the introduction of bending machine?

A metal bending machine forms metal pieces into diverse shapes including plates, strips, rods, tubes, and more. Metal bending machines shape metal for an array of products such as car panels, aircraft parts, cabinets, gutters, architectural features, and more.

Over time, we&#;ve discovered more uses for bent metal. This growing demand has prompted the evolution of metal bending machinery. Read this brief history of metal bending machines to learn more.

Shifting From Iron to Steel

In the past, curved metal structures were usually made from iron. Blacksmiths could curve small pieces of iron through hot forging because of the material&#;s softness. The blacksmith would take the workpiece (usually iron), heat it, and shape it through hammering and pressing.

While trip hammers were used in Imperial China hundreds of years before they appeared in Europe, blacksmiths in medieval Europe began using water-powered hammer forges in the 11th century. With this tool, they were able to create large quantities of steel sheets. This changed the metalworking field, resulting in the formation of specialty metalworking guilds.

The First Sheet Metal Bending Machine

During the 18th century, metal started replacing wood in metalworking equipment. This change in material, combined with a more sophisticated system of levers and controls, made metalworking easier. And just as the introduction of mass-produced sheet metal helped the industry take off, the invention of the reversing rolling mill at the end of the 18th century increased mechanical sheet metal production.

The first metal bending machines were made in the 19th century. With these machines, the locking lever and bending tools were powered by hydraulic cylinders and controlled with a lever valve. Eventually, the shears were also powered hydraulically.

th

Century

The twentieth century saw massive changes in the history of metal bending machines. Starting in the s, bending systems became increasingly electrified. The first control systems operated clamping, bending, and cutting.

Numerical controls (CNC) for machine tools were developed in the s. The operator could pre-set values for clamping, bending, and cutting. In the mid-&#;s, steel bending machines became capable of curving large steel beams accurately and at a much lower cost. This improved process led to an increase in curved steel in construction.

At the end of the s, operators could use graphic control systems on their metal bending machines. Soon thereafter, operators could input values using touchscreens. CNC metal bending machines make the once extremely difficult tasks of metal-bending so much easier, allowing metal fabricators to create precisely bent parts for offices, airport terminals, mega stores, and much more.

1. What are the types of bending machines?

The bending machine is divided into three types: manual bending machine, hydraulic bending machine, and CNC bending machine. Manual bending machine is divided into mechanical manual bending machine and electric manual bending machine. According to the synchronous mode, the hydraulic bending machine can be divided into mechanical synchronous bending machine, torsion axis synchronous bending machine, machine-hydraulic synchronous bending machine, and electro-hydraulic synchronous CNC bending machine.

According to the movement mode, the hydraulic bending machine can be divided into an up-moving type and a down-moving type. The down-moving type is when the workbench and the workpiece on the workbench move upward together, and the slider does not move. At present, it is relatively rare in the domestic market, and most of them are up-moving. The workpiece does not move, and the slider moves downward. According to the control mode, it can be divided into ordinary hydraulic sheet metal bending machine, economical CNC bending machine, and electro-hydraulic synchronous CNC bending machine.

2. Introduction to the function of the bending machine

The bending machine is a kind of forging machinery. Its main function is to perform sheet metal processing on sheets, especially large sheets. By matching various molds, sheets can be bent, stretched, Rounded, punched, etc., and widely used in light industry, aviation, shipbuilding, metallurgy, instrumentation, electrical appliances, stainless steel products, steel structure construction, and decoration industries.

The bending machine includes a bracket, a workbench, and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base is composed of a seat shell, a coil, and a cover. In the depression of the seat shell, the top of the depression is covered with a cover plate.

When in use, the wire is energized to the coil, and after energization, an attractive force is generated on the pressure plate, to realize the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and it can also process workpieces with side walls. The bending machine can meet the needs of various workpieces by replacing the bending machine mold.

The hydraulic bending machine adopts a steel plate welding structure; vibration aging eliminates stress, and the frame has good rigidity and stability; it works smoothly, is safe and reliable, and is easy to operate; it achieves the ideal bending effect through coordinated control of the electrical and hydraulic systems.

3. Main components and structure of the machine

1. Slider part: The slider part of the hydraulic bending machine is composed of a slider, an oil cylinder, and an automatic stop material fine-tuning structure. The left and right oil cylinders are fixed on the frame, and the piston (rod) drives the slider to move up and down through hydraulic pressure.

2. The workbench is composed of a movable workbench and a vertical plate, which are processed by a large CNC milling and boring machine.

3. Synchronization system: This machine is composed of a torsion shaft and arm to form an automatic synchronization device, with a simple structure, stable and reliable performance, and high synchronization accuracy. The automatic stop is regulated by the motor and the ESA system displays the value.
