Electric Kraftfomer 350 Sheet forming Machine Power Hammer Shrinker Stretcher
KRaftformer 350 Introduction :
The Kraftformer 350 is part of the medium-force Kraftformer range with motor drive.
Depending on the workpiece to be machined, the operator can adjust the number of working strokes to any value between 220 and 600 strokes per minute continuously. Low speeds are particularly suitable for shrinking, stretching and for straightening and precision finishing. Thanks to the high stroke rate, the machine is also widely used for doming (dishing) and planishing, boosting productivity. This Kraftformer is capable of machining steel sheets of up to 3 mm in thickness!
For our Kraftformers, we offer a wide range of tools (tools are not included in the scope of delivery of this machine).
Max. forming capacity
Steel 400 N/mm²: 3.0 mm
Aluminium 250 N/mm²: 4.0 mm
Inox 600 N/mm²: 2.0 mm
Summary:
Shrinking and stretching are indispensable operations in aircraft manufacturing, mainly
for correcting and adjusting of pressed parts of all sorts. The special machines and tooling
offer a highly efficient solution to assure precise fitting together of the individual parts.
Usage:
the sheet forming machine changes the traditional style of sheet forming by
manaually.reduce labour intensity and increase the productivity. it is widely
used to making palne. train.automobile,ship,electronic,light industry and etc.
it solved the technology that general dies are substituted for special dies.
Service And Maintenance:
The machine is of simple structure and does not require special maintenance.
However in order to prolong its working life please pay attention to the following item:
Lubricate all relevant points of the machine as per requirement of the lubrication
information plate, see figure below.
When stopping the machine be sure to push the selector button to “adjust” position,
step on foot switch S2 to lift the plunger for 1—2 seconds and then stop and switch
off power.
Before starting the machine be sure to clean up the work piece surfaces without
leaving a single spot of grease so as to make it easy for the shaping and prolong
the working life of dies.
Often check on the tension of the belt. If the machine is to lay idle for long period
of time the belt is to be loosened. Be sure to change belt in good time when it is
found damaged.
Emergency switch is not for stopping the machine in normal conditions. Do not use
it unless in emergency.
