In the realm of stamping automation, the pneumatic feeding machine stands as a stalwart with its simplistic design and budget-friendly pricing. This article delves into the intricacies of this early feeding apparatus, exploring its components, functionalities, and diverse applications across industries.

Unveiling the Core Structure

The pneumatic feeding machine boasts a streamlined architecture, comprising a main body, guide columns, and a rear seat forming the foundational framework. Within this structure, the main body houses feeding and clamping mechanisms, control apparatus, and transmission mechanisms.

Powering Precision with Cylinders and Pistons

The system leverages cylinders and piston assemblies to harness the directional and size differentials of compressed gas. Cylinders, pistons, and piston rods work in tandem to drive feeding, clamping mechanisms, and transmission mechanisms. This harmonious interplay, complemented by a dedicated feeding component, ensures meticulous, high-speed, and secure material feeding in stamping presses.

The Pneumatic Ballet: How It Operates

As compressed gas infiltrates the main body cylinder chamber through the intake orifice of the front plunger head, a choreography of movements is set into motion. The gas traverses the air delivery orifice of the delivery pipe and the ventilation orifice of the piston rod, reaching the piston chamber of the slider. This orchestrated sequence propels the piston, activating the clamping rod and clamping plate. Overcoming spring force, these elements secure materials onto the protective plate, ushering in precise and secure material feeding.

Simultaneously, the gas from the intake orifice propels the piston backward, while the gas entering from the rear plunger head propels it forward. This reciprocal motion facilitates the active feeding mechanism, ensuring a seamless material flow during the stamping process.

Fixed Feeding Mechanism: A Sturdy Foundation

Nestled within the main body, the fixed feeding mechanism employs lifting rods and clamping plates. As the piston-driven movement lowers this mechanism, it clamps the workpiece against the wear-resistant plate. The active feeding mechanism then advances the workpiece, and as the clamping plate of the fixed feeding mechanism reaches its zenith, it firmly secures the workpiece during stamping on the press.

Guiding the Way: The Feeding Assembly

Situated at the rear end and connected to the guide columns, the feeding assembly plays a crucial role. Equipped with material guiding wheels on both sides of the rear seat, it minimizes friction for incoming workpieces. The feeding support outside the rear seat incorporates a feeding rod, facilitating workpiece elevation. Length adjustment screws and cushioning springs, installed in the rear seat, regulate the feeding quantity, ensuring optimal performance.

The Transmission Mechanism Unraveled

A vital component, the transmission mechanism, features a floating rod connecting to the main body. This connection, in turn, links to a floating piston through an active cylinder. The active cylinder interfaces with the press cam, initiating the entire feeding machine’s operation.

The active cylinder comprises air chambers, and the floating rod incorporates air delivery orifices. These orifices convey gas from the orifice to the chamber, with exhaust orifices situated in the lower section of the active cylinder. A floating piston, connected below the floating rod, features a floating piston chamber in the main body with a passage to the air delivery orifice. The main body connects to the air intake joint with a buffer.

Mastering Control: The Art of Precision

The control apparatus for the air path is a finely tuned system involving two air delivery pistons from the intake orifice to the air chamber. This ensures seamless switch control, with adjustment holes and speed screws regulating the air volume, enabling precise and efficient operation of the pneumatic feeding machine.

Widening Horizons: Applications Across Industries

The pneumatic feeding machine finds versatile application in continuous stamping processes across various industries, including hardware and electronics. It accommodates a spectrum of materials, encompassing both metal and non-metal sheets, wires, and tubes. Operating at impressive speeds of up to 280 strokes per minute, it emerges as the ideal choice for the production of stamped products with moderate precision requirements.

In conclusion, the pneumatic feeding machine not only retains its market presence but also proves to be an indispensable asset in the realm of stamping automation. Its reliability, precision, and adaptability across industries make it a cornerstone in the production of high-quality stamped products.
