Principle and design of automatic punch feeder
- Dec 04, 2018 -

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. The punch feeder manufacturer also develops and produces according to the different customer's plates and functional requirements. Punch feeders with various characteristics. 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 feeding, and after the feeding is in place, the punch passes down the punching, and then the punch returns to the original position under the driving of the crankshaft, and the feeding device feeds again (the circulating feeding is repeated, and There is a reciprocating feed), the punch is punched down again, and it circulates 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 the 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.
