One of the more traditional methods of machining metal materials, the press brake, also known as the bending machine，has been around for more than a hundred years. Today, press brake have evolved into highly advanced machines powered by hydraulic systems and computer technology.
Why use the press brakes?
As one of many important pieces of equipment in the metals industry, press brake help supply custom parts to a wide range of industries, including automotive, aviation, agriculture, energy, military, transportation, and more. These modern press brakes bend sheet and sheet metal easily and efficiently, providing simple and complex components for a variety of industries, and a good metal service center will always help determine which machine is best for the job and provide solutions for bending needs.
Having a good press brake on hand is crucial to the operation and success of any metal manufacturer!
How does the press brake work?
The press brake works by using punches and molds that are set at predetermined angles to bend or cut metal into various shapes and forms.
What will affect the brake operation?
Sheet metal and sheet bending may seem simple enough to the uninitiated, but the truth is that it is often the most complicated process in many metal working workshops. Such as bending Angle changes, bending material effects, space changes, parts inconsistency and so on.
1. Bending Angle changes
First, its severity depends on the die opening. The smaller the die opening relative to the thickness of the material, the greater the Angle change. The main reason for the existence of different die angles in air bending is not to bend at different
angles, but to allow the punch to drop far enough into the die space to overbend for springback.
Second, changes in material thickness can affect the bending Angle, especially for narrow dies. When using narrow mold openings, having precise depth of penetration becomes even more critical. Changing the penetration depth of the wide die changes the bending Angle only a little; The bending Angle changes dramatically by changing the very small penetration depth with a narrower die.
2. Different bending materials determine different bending methods
It has been suggested that when designing parts for sheet metal applications, you must take a realistic view of such variables as material properties, consistency of filling and tempering, yield strength, tensile strength and grain direction, but most importantly, variation in material thickness. Therefore, when we use different bending materials, the thickness of materials is also different. According to the above article, the thickness of materials will affect the change of Angle, and the relationship between Angle and material thickness is mutually influencing. Different metal materials have different ductility, so choosing a better bending mode suitable for them can help us reduce errors and increase output.
3. Consistency of parts and materials
High quality materials will help any brake operator, whether they are older brakes or one of today's advanced bending systems, especially for raw material control, so that precision bending can be operated effectively. The same goes for parts. Different batches of parts, different surface conditions, or changes in the properties of different materials, or even any color can affect the bending effect.
Small changes can make all the difference, and the low dimensional tolerances of molded parts are also a competitive advantage. Therefore, we recommend working with the same manufacturer or service center as much as possible, and don't mix suppliers unless necessary.
The precision and repeatability of modern press brakes and precision grinding tools make bending faster and more predictable than in the past. Precision bending operations can achieve some very strict tolerances, but it takes time, money and effort to achieve.
So it is important to know the load limits and press power of each machine, because if the wrong tonnage or length is used, it can damage or destroy the equipment.
