The press brake V dies are essential to fabricating a variety of metal parts. Choosing the right one depends on the material being bent and the thickness of the metal. When bending thin material, you need the smallest V die, while thicker material needs the largest V die. To make your job easier, here are some tips for selecting the right press brake V die:
Steel bonded cemented carbide
Steel bonded cemented carbide press brake dies are designed for use with press brakes. These dies are made from steel powder and an alloying element such as cobalt. The process produces a steel alloy that exhibits high hardness and wear resistance. It is less susceptible to fracture than conventional steels, and can be cut and shaped. Its high carbide content makes it harder than most other steels.
The two main parts of a press brake are the die and the punch. The die is the upper portion, while the punch is the lower part. The two are matched to produce the desired profile. When they are used together, they provide a high degree of precision.
Urethane
Urethane is a versatile material that can be used as a die or punch for press brake applications. The material is almost universally used as a die, and the company that produces your tooling will choose the right type for your needs. The company will consider the amount of deflection and hardness needed for the die, as well as the design of the tool to control spring back.
Urethane press brake tooling is one of the cheapest options when bending metal. Press brake tooling made of urethane is available in single-, double-, and four-V designs. Triangular-shaped V-Pads are also available in various sizes to ensure mar-free bending.
Steel alloys
Press brakes use interchangeable punches to shape metal blanks during the forming process. Without a die, a punch is just a fancy paperweight, while the die and punch interact to form a part on both sides. Understanding the functions of these two parts will help fabricators choose the best press brake dies for the job at hand.
Steels used in press brakes are made from several different alloys. Some of these steels are hardened while others are tempered. The main performance requirements are wear resistance and toughness.
Complicates with press brake V dies
There are many factors to consider when choosing a press brake V die. One of the main things to consider is the ratio between the inner radius of the V die and the material thickness. The inner radius should be at least 1.5 times the thickness of the material. Then, consider how much space is available for spring back, which is the angle at which the die opens and closes. Then, determine whether the die is equipped with enough resistance to withstand the force of the press brake.
A press brake has two types of dies: the upper and lower die. The upper die features an 88-degree and 45-degree punch, while the lower die features a 30deg and 20-degree punch. The purpose of the dies is to control the shape of the product as it passes through the press brake.
Backgauge
Before you can determine whether you need a back gauge, you must first understand the concept of capacity. Capacity is a measure of the amount of force a press brake can exert on a work piece. The greater the capacity, the more force a press brake can exert on a work piece.
Tonnage can be adjusted in a variety of ways. Most modern hydraulic brakes have a high level of tonnage control. The lower beam moves the die upward into the punch, while the upper beam holds the punch holder. The back gauge can be adjusted in several ways. The length of the bend line will depend on the origin, which is set at the center of the v opening. All other positioning of the back gauge will be controlled by the back gauge’s position.
