In this article, we will introduce the Press Brake Dies<\/strong>\u00a0used in press brake machines, discussing the different types of press brake dies and the appropriate terminology to describe them.<\/p>\n

1.\u201cPress Brake Dies\u201d vs. \u201cPress Brake Tooling\u201d and \u201cPress Brake Tools\u201d<\/b><\/strong><\/h2>\n

We understand that these terms may confuse customers looking to purchase press brake dies. “What keywords should I use to find the products I need?” Here, we will clarify these terms and help you find the exact products you seek. By the way, \u201cbrake press die\u201d is also the correct name.<\/p>\n

(1)\u00a0<\/b>Tool and Tooling<\/b><\/strong>\u00a0<\/b><\/strong><\/span><\/h3>\n

Tool or tooling is a general term meaning “a set of equipment used for a particular purpose.” Various types of dies can be referred to as tools or tooling.<\/p>\n

(2) Die<\/b><\/strong><\/span><\/h3>\n

Die usually refers to toolings used for forging, stamping, extrusion, and other solid-state forming processes. The tools used on press brake machines are generally called dies, which is why we use the term “press brake die” in the title of this article. A die typically consists of an upper die<\/b><\/strong>\u00a0e un\u00a0lower die<\/b><\/strong>. As shown in the picture below, the cookie cutter is the die, and the desktop can be the lower die.<\/p>\n

The profile of the die used on the press brake is generally shown in the figure below. In this picture, we can see that \u2460\u00a0represents the upper die, \u2461\u00a0represents the lower die, and \u2462\u00a0represents the workpiece being processed.<\/p>\n

 <\/p>\n

In the specific production process, the lower die on the press brake machine remains fixed while the machine controls the movement of the upper die to shape sheet metal into specific forms. During this process, the upper die applies a force ranging from tens to hundreds of tons to the workpiece. Because of this, we also refer to the upper die as a “punch.” Well, isn’t this very vivid? It is a very powerful “punch.”<\/p>\n

However, when searching for related information, using keywords such as press brake dies\/tooling\/tools is acceptable as they all refer to the same type of product.<\/p>\n

(3) Mold<\/b><\/strong><\/span><\/h3>\n

It should be noted that using the term “mold” on a press brake machine is inaccurate. Because mold is used for shaping liquid or soft materials. For example, in injection molding or casting processes, molds shape liquid or soft materials (such as clay or plastic) into specific forms. For instance, a cake mold shapes cake batter, as shown in the image below.<\/p>\n

2. Shapes of Press Brake Dies<\/b><\/strong><\/h2>\n

When purchasing press brake dies, the most important attributes are the length and cross-sectional shape (also called profile). The profile is the most critical attribute and directly determines the purpose of the die. However, there are many different profiles, and you may have struggled to describe the shape you need. Here, we will summarize some common profiles of press brake dies in a list with corresponding images and introduce their main uses to assist you. And this article is the part 1 of a series of articles about press brake dies. In this part we will just introduce the types of lower dies.

(1) Press Brake Lower Die Types<\/b><\/strong><\/span><\/h3>\n

The most common types of press brake lower dies can be divided into three categories based on the shape and number of grooves on these dies. Press brake dies can be classified as V-dies, U-dies, and Z-dies. Among them, V-dies are the most widely used type. Let’s introduce these three different types of dies.<\/p>\n

(2) V-Die <\/b><\/strong><\/span><\/h3>\n

The V-die is the most frequently used type of die in press brake operations. As the name suggests, it has one or more V-shaped grooves on its upper surface.<\/p>\n

Depending on the number of V-shaped grooves, V-dies can be further classified as 1V die, 2V die, 3V die, and 4V die. Having multiple V-shaped grooves on one die serves two main purposes:<\/p>\n
