To support the circumference of the roll pin, roll pin punches have a small projection in the center of the pin tip. In general, solid pins should never be punched with roll pin punches because the tips are not flat. Solid pins will be marred or marked if a roll pin punch is used on them. Features of Roll Pin Punch Keep the punch perpendicular to the work surface. Once the tip is in place, ensure that the shaft is perpendicular to the workpiece. Dot punches are similar to centre punches, although they have a sharper point, ground to 60 degrees (see below). They tend to be used on sheet metals, as they are a ‘lighter’ version of the centre punch. The main punch is fitted with its body with a spring. Spring remains settled through a lever head. When marking is to be done, its lever head is pressed. Through this pressure, the main punch would be pressed and do the marking.

Punch tools are built to last and are reliable because they are made of high-quality materials and can withstand repeated use.

Unlike driving punches, which have pointy ends rather than a flat face, drive punches usually have a flat face. The pin punch is a tool that is used to remove bolts and pins and has a straight shank with a variety of applications. A pin punch is primarily used for the purpose of removing bolts or pins from a hole that has already been opened by a drive punch, and after the bolt or pin has been loosened, it can be removed. You should choose a roll pin punch whose compressed diameter does not exceed the pin’s compressed diameter. The surrounding metal in which the pin is seated can be damaged if a punch larger than the pin is used. In addition, it is not recommended to use a roll pin punch that is smaller than the compressed diameter of the pin. Roll pins are hollow in the center, so the punch may be able to drive through it. Before using the center punch, some preparation is required. Measure out and mark the exact drill hole placement. It’s best to mark this in a clear X, with the hole location where the two lines intersect. Tablet punches and dies are also known as tablet tools or punch and die tooling, or compression tools. It is essential to have superior quality tablet tools for excellent performance, high productivity, and long tooling life.

Two types of brakes are provided with punching machines, the first is the normal brake and the second is the emergency brake, which is designed to stop the machine in an emergency situation in case of a mechanical malfunction or failure. In the future, these machines will have more advanced sensors to ensure that they provide the user with a safe and reliable operation when the technology will become more advanced. The punch’s blow can be limited or controlled with the lever head. Its main punch has a 60° or 90° angle. Figure shows this type of punch. In most cases, solid punches are used for driving or creating impressions on a workpiece. They are typically used for driving objects like pins. It is critical to cool these down in cold water when using them in hot jobs. Because holes made with a solid punch are not precisely measured and are not clean, they are used in rough work. 4.

The centre punch is made form mild steel with the point hardened and tempered so that it withstands impact with the material it is marking. The dot punch is a lighter and thinner version of the centre punch and is used basically for the same job. However, it is more accurately as the dot produced is smaller.

Bell Punch), बेलनाकार वस्तुओं का केन्द्र पंच Punch करने के लिए बैल पंच Punch का प्रयोग किया जाता है। बैल पंच (Bell Punch) का बाह्य आवरण एक घण्टी (Bell) के आकार का होता है। बैल पंच (Bell Punch) के ठीक सेन्टर में एक पंच Punch लगा होता है। यह पंच Punch स्प्रिंग के द्वारा ऊपर उठा रहता है। जब किसी बेलनाकार वस्तु का केन्द्र ज्ञात करना होता हैं तो बैल पंच (Bell Punch) को ठीक उसके ऊपर लम्बवत टिकाते हैं तथा स्प्रिंग (Spring Loaded) पंच को नीचे मारने से केन्द्र (Centre) ज्ञात होता है। ऑटोमैटिक पंच (Automatic Punch) ऑटोमैटिक पंच (Automatic Punch), इस पंच Punch में पंचिंग के लिए हैमर से चोट लगाने की अवश्यकता नहीं पड़ती है, इस लिए इसे ऑटोमैटिक पंच (Automatic Punch) कहते हैं। ऑटोमैटिक पंच (Automatic Punch) एक खोखली बेलनाकार बॉडी (Body) जिसे बाहर से नर्ल (Knurl) किया होता है। इसके ऊपर एक कमानी स्प्निंग युक्त कैप होती है, इसे भी नर्ल किया गया होता है। इस कैप को नीचे दबाने पर कमानी स्प्रिंग एक हैमरिंग मैकेनिज्म को मुफ्त (Release) करती है, जो पंच Punch के निचले प्वाइन्ट पर केन्द्र बनाने के लिए आघात करता है। कैप को घुमाकर ऊपर करने से निशान गहरा आता है। सॉलिड पंच (Solid Punch) Also known as letter stamps or number stamps, letter punches are used to emboss the impression of a letter or number into a workpiece. They are most common in the reverse image, this allows the end result to be immediately readable, however, they may be made as a positive image.

Depending upon the pitch of the teeth (Distance between the two consecutive teeth), blades are classified as: As a result of their interior composition, punch tools are often categorized as hollow or solid tools, depending on whether they are hollow or solid. Punch tools with hollow interiors are as you would expect, hollow in nature, as opposed to punch tools with solid interiors, which are solid in nature. For drilling in metal, a centre punch ensures safety and accuracy. The indentation it makes in a workpiece creates, not only a visible reference point but also guides and stabilises the drill bit to prevent slipping, which may cause injury and damage to the workpiece.
