Punching machines offer a whole range of possibilities when it comes to sheet metal fabrication work. You can create everything from washing machine drums to the interior of ticket vending machines!
What is punching?
Punching creates contours, form sheets and modify surfaces. It is fast, efficient, productive and an automated process which offers a wide range of options.
- It is a cutting process – where a sheet is cut in two with a single stroke.
- Nibbling is the process of making rows of little holes resulting in a contour of any shape and size.
- Forming creates new dimensions – different tools turn the punching machine into an all-round talent for tapping, embossing and marking.
The basis of this process starts with a TRUMPF machine, in order to get the versatility out of the process comes only with the wide variety of tools. Additionally, the use of automated components for loading and unloading the machine means that automated production is possible.
Think of a punching machine as a hole puncher. You place the paper between the top and bottom layer, press firmly on the device and a hole is cut, collected then disposed of and you are left with a precise, clean hole within your paper.
The process takes place in 4 phases:
Stage 1 – When the punch touches the sheet, it first of all deforms it.
Stage 2 – This is followed by cutting, the level of tension produced inside the material is so great that the sheet breaks along the contour of the cut.
Stage 3 – The piece of metal cut out ‘the punching slug‘ is ejected in a downwards direction. The punch will then move up again, should it take the sheet of metal with it…
Stage 4 – The stripper will detach the sheet from the punch.
There are many different models from varying years available to purchase, to show you just a few see below:
Each machine has differing capabilities based on what material you will be cutting, how many hours you will be running the machine and the force of the punch.
For example: TRUMPF Trumatic 500 Year 1995
This machine offers fast production, with short set up and high component quality. Its wide range of applications makes it the ideal ‘all-rounder’ machine that never goes out of style. The machine provides a more compact, yet sturdy ‘C’ frame.
- 18 tool stations available for economical production
- Electro-hydraulic RAM within the punching head has been developed into a virtual 3rd axis by TRUMPF
- Head rotation offers another axis of operation allowing for the rotation of all tools, including forming tools and multitools.
- TRUMAGRAPH CC 220 S Control- fast and powerful and manages all operating and service functions of the machine.
- User friendly operation.
What types of products are created with punching machines?
- Point of purchase displays (Newspaper stands, trolleys, sweet display units etc)
- Air, fire and smoke control dampers
- Metal cases – to store and transport high value equipment
- Waste containers
- Radiator grills on cars
- Washing machine drums
- Sinks made from stainless steel
- And many many more!
