PUNCH MARKING SYSTEM FOR HOT AND COLD PRODUCTS

Punching is the technology for obtaining a permanent marking directly indented in hot or cold metal products; Green Project developed a complete range of punching machines based on the PUMA concept, specifically designed for the steel industry, which are showing excellent operation thanks to their high performances and reliability in conjunction with easy operation and really low operational costs.
The systems presented hereafter offer a suitable solution for any need:

  • PUMA HAMMER: heavy duty punching device with single, hard metal chisel, mainly used in C.C. plants
  • PUMA SPEEDY: multi-pin punching device, mainly used in hot and cold rolling mills for plates and pipes
  • PUMA MONO: single pin graphic punching device, mainly used for beams, bars, samples.




Puma Hammer

PUMA Hammer is a heavy duty device suitable for use in extremely harsh C.C. environment for marking billets, blooms, slabs at very high temperature; it uses a very hard, wedge shaped single chisel, moving along X-Y directions in the work area; segments are sequentially indented, moving and rotating the chisel at high speed; this assures a good penetration and, differently from punching a character in a single shot, assures to have always the whole character even if the surface is uneven.
Special font design in order to print unmistakable characters.
Special features are available for marking stainless steel and in general all special steels that, when flame cut with addition of iron powder, show thick scale.
PUMA Hammer is basically composed by:

  • the punching head
  • the pneumatic cabinet
  • the control unit


Technical features

Characters size:height from 10 mm – 25 mm
N. of lines:max. 3
N. of characters each line:max. 16
Depth of indentation:about 2 mm, depending on material and temperature
Marking speed:min. 0,65 s / character
Specialsreverse marking (upside down)
stainless steel package

System configuration

  • compact head for easy installation in any plant layout
  • pneumatic driven punching command
  • easy maintenance and quick chisel replacement
  • local control box for set up and maintenance
  • full control of marking parameters, adjustable in run - time mode by local or remote interface
  • marking data entered by local HMI or downloaded by remote interface

Our custom automatic reading devices AURS (fixed position and portable) for tri-dimensional recognition of bar codes, letters and numbers written by PUMA HAMMER punch marking system are available (see relevant data sheet)





Puma Speedy

PUMA Speedy is the system developed by Green Project for punching metal products out of hot and cold rolling mills (like plates, pipes, beams, etc.); the main feature of the system is the capability to punch a large number of characters in a very short time; this is obtained by moving one or more multi-pin packages (with configurable pins number) in X-Y directions, during the movement each pin marks simultaneously a portion of the message. Characters are defined by a matrix of dots indented in the metal surface, penetration force is adjustable.
PUMA Speedy is basically composed by:


Technical features
Product Temperature:from ambient to 950°C
Pin arrangement:modular, from 5 to 15 pins
Font matrix:7, 9, 12 or 16 dots in height
Character type:letters, numbers, special characters (logos), Data Matrix code
Characters size:height from 3 mm to 25 mm
N. of lines:max. 4
N. of characters each line:max. 90 each line
Depth of the indentation:about 0.3 – 0.5 mm

System configuration

  • pneumatic driven punching command
  • different pin models and configurations (according to the specific needs)
  • modular assembly
  • easy removal and maintenance of the punching pins
  • full control of marking parameters, adjustable in run - time mode by local or remote interface
  • marking data entered by local HMI or downloaded by remote interface
  • multi-platform (Java) tool for characters and logos editing

Our automatic reading devices AURS (fixed or portable hand held devices) for recognition of data matrix pin stamped by PUMA Speedy are available (see relevant data sheet)





Puma Mono

For applications where few characters are to be marked or the space is limited, Green Project proposes its TEMA MONO punching unit, equipped with a single pin which moves in a X-Y area, marking the characters in a graphic mode, i.e. defined as a sequence of indented dots approximating a continuous line.
Various models are available, with different marking areas. A special device has been developed for installation on a robot, which performs the writing operation combining its high precision trajectories with the high frequency percussion of the pin.

Technical features
Product Temperature:from ambient to 950°C
Character type:letters, numbers, special characters (logos), Data Matrix code
Characters size:height from 2 mm to 25 mm
N. of lines:one or more, depending on work area and character size
N. of characters each line:depending on work area and character size
Depth of the indentation:about 0.1 – 0.5 mm
Marking speed:min. 0.6 s / character

System configuration

  • pneumatic driven punching command
  • different pin models and configurations (according to the specific needs)
  • easy removal and maintenance of the punching pin
  • full control of marking parameters, adjustable in run - time mode by local or remote interface
  • marking data entered by local HMI or downloaded by remote interface

Our automatic reading devices AURS (fixed or portable hand held devices) for recognition of data matrix pin stamped by PUMA Mono are available (see relevant data sheet)
