CNC Wila motorized wave mechanical crowning table ensure precise sheet bending profiles in full length
Wila New Standard Tool Holders (Clamping, Crowning and Bottom Tool Holders) make it possible to change tools very quickly. When combined with our state of the art New Standard or American Style Tooling, they also provide maximum accuracy, flexibility, durability and safety. Award-winning innovations like Safety-Click®, Smart Tool Locator® and the WILA E2M® (Easy to Move) system also make changing even the heaviest tools easier and safer.
WILA Crowning systems fully compensate for the deflection in press brakes. This results in a consistent bending angle across the entire length of the machine. WILA New Standard Crowning Systems utilize a series of patented adjustable wedges known as Wila Waves.
Eliminate press brake tolerances: Tx- and Ty axis
The accuracy of the bending process is determined by the tolerances along the Ty and Tx axis: vertical and horizontal axis. The Ty axis value is decisive in determining the parallelism between punches and dies. The Ty axis adjustment, which is normally incorporated into the bottom of the Crowning Systems and Bottom Tool Holder, is able to easily and effectively correct accumulated machine tolerance across the length of the whole machine. The Tx axis value relates to the position of the bending axis in relation to the back gauge, critical for producing accurate flange lengths. The Tx axis adjustment has been included in all Tool Holders suitable for press brakes featuring the Universal Press Brake (UPB) hole pattern.
CHOOSING THE BEST PRESS BRAKE TOOLS FOR HEMMING SHEET METAL
With the growing demand for both higher quality and safer products, hemming sheet metal is becoming an increasingly common operation at the press brake. And with so many press brake hemming solutions on the market, determining which solution is right for your operations can be a project in itself.
Hemming sheet metal involves the folding of one layer of material over another in order to create a soft or rounded edge. It is used in a wide variety of industries including refrigeration, cabinet making, office equipment manufacturing, food processing equipment, and shelving and storage equipment just to name a few.
Historically, hemming has typically been used on materials ranging from 0.5mm to 1mm mild steel. However, with recent improvements in available hemming technology it is not uncommon to see hemming done on 1 – 3mm., and in rare cases even as thick as 4mm thick material.
Hemming sheet metal products can improve aesthetics, eliminate exposure of sharp edges and burrs in areas where the part would otherwise be dangerous to handle, and add strength to the finished part. Choosing the right hemming tools depends on how frequently you will be hemming and which material thicknesses you plan to hem.
Combination sheet bending top punch and bottom die (U-shaped hemming dies)
Max. material thickness: 1.3mm
Application: Best for occasional hemming of thin materials. Ideal for “crushed” hems.
Universal bending: Yes, but limited.
The combination punch and die (or U-shaped hemming dies) utilize a 30° acute punch with a flattening jaw on the front and a U-shaped die with a wide flat surface at the top. As with all hemming methods, the first bend involves creating a 30ۡ° pre-bend. This is achieved by the punch driving the material into the U-shaped opening on the die. The material is then placed on top of the die with the pre-bend flange facing upward. The punch is again driven downward into the U-shaped opening on the die while the flattening jaw on the punch progresses through the flattening stage.
Due to the fact that the U-shaped hemming die has a solid wall of steel beneath the area where the flattening operation occurs, the high load capacity provided by this design works very well in creating “crushed” hems. Due to the use of an acute punch for the pre-bend, U-shaped hemming dies can also be used for universal bending applications.
The tradeoff to this hemming tooling design is that as the flattening jaw is located on the front of the punch, it must be fairly shallow in depth to avoid interference with the material as it swings upward to create the 30-degree pre-bend. This shallow depth makes the material more prone to slip out of the flattening jaw during the flattening stage, which can cause considerable damage to the press brake’s back gauge fingers.
Use Two stage sheet metal hemming bending dies (spring-loaded inside)
Max. sheet bending material thickness: 1.6mm mild steel or stainless sheet material
Application: For infrequent to moderate hemming applications of various material thicknesses.
Universal Bending: Yes
As cnc synchro press brakes and software increased in capability, two stage hemming dies became very popular. When using these dies, the part is bent with a 30° acute angle punch and a hemming die with a 30° acute angle V-opening. The upper sections of these dies are spring loaded and during the flattening stage, the pre-bent material is placed between a set of flattening jaws on the front of the die and the upper flattening jaw is driven downward by the punch during the stroke of the ram. As this occurs, the pre-bent flange is flattened until the leading edge comes into contact with the flat sheet.
While fast and highly productive, two stage hemming dies have their drawbacks. Because they use a spring loaded top, they must have enough spring pressure to hold the sheet without dropping even the slightest until the first bend begins. If they fail to do so, the material could slip beneath the back gauge fingers and damage them as the first bend is made. Furthermore, they require a V-opening that is equal to six times the material thickness (i.e., for material with a thickness of 2mm, spring loaded hemming dies require a 12mm v-opening).
Also there is one Doubling as a die holder, Dutch bending tables also feature the ability to interchange 30-degree dies, which also contributes to their ability to hem a wide variety of material thicknesses. This makes them extremely versatile and results in a dramatic reduction in set-up time. Having the ability to change the v-opening, combined with the ability to use the hydraulic cylinders to close the flattening jaws also makes it possible to use the system as a die holder when not in use for hemming applications.
No one hemming tool is suitable for all hemming applications. Choosing the right press brake hemming tool depends on which materials you plan to bend and how frequently you will be hemming. Consider the material thickness range you plan to bend, as well as how many setups will be required to complete all necessary jobs.
