The punch feeder, as the name implies, is the loading robot used in
the punching machine. In the metal processing industry, the use of
the feeder is quite extensive.
Punch feeder manufacturers will also develop and produce punch feeders with
various characteristics according to different customer's plates
and functional requirements.
The principle and design of the automatic feeder for punching
machine may not be very clear. Let's take a look at what it is:
The die of the punching machine is different (under the discharge,
on the material), the material is not the same (there are flat
plates, there are coils), the structure of the feeder is also different, the basic working principle is that the die is
punched after the punch is started. The head stops at the top dead
center of the crankshaft work.
The feeding device starts to feed, after the feeding is in place,
the punch passes down the material, and then the punch returns to
the original position under the driving of the crankshaft, and the
feeding device feeds again (divided rolling feeding, and
reciprocating feeding), and the punch is pressed downward again. ,
loop back and forth.
The punch feeder is essentially a loading robot, suitable for
stamping processing in the bearing industry, hardware industry, and
standard parts industry.
It can automatically feed and unload, improve production
efficiency, ensure product quality, improve workers' labor
intensity and ensure personal safety.
The beat and the punch are synchronized, continuous production, the
overall structure is simple and compact, the transmission is
stable, the performance is reliable, the use is safe, the operation
is convenient, the processing is convenient, the assembly and
disassembly, the adjustment, the maintenance and the manufacturing
economy are economical. It has a large application prospect in the
cold extrusion processing industry, especially in the bearing
stamping process.
The most basic requirement for automation of stamping processing in
automatic feeders is also the fundamental guarantee for
multi-station stamping on a set of molds.
The distance that the automatic feeder feeds the material each time is called the feeding step, and the
feeding step can be determined according to the shape and size of
the stamping part and the needs of the stamping process.
Feeding process: The motor drives the crank to rotate through the
V-belt drive and single-stage gear transmission, and sends a
certain amount of thin steel plate to the punching table.
The punching process: the flywheel drives the crank lever
mechanism, and the crank in the crank rocker mechanism is the
active member, which drives the rocker to swing, and the rocker and
the ratchet are coaxial, thereby converting the continuous
reciprocating swing of the rocker into a one-way intermittent
motion of the ratchet, the ratchet It coincides with the central
axis of the roller shaft, and finally a certain amount of sheet
material is sent to the working position by the pressing of the
roller shaft.
