The structural characteristics, working principle and application scope of metal pneumatic punching machine
Metal pneumatic punch structure
What is a metal pneumatic punch? Metal pneumatic punch is a kind of high-speed punching equipment with high punching accuracy and high speed, which uses a compressor to
generate gas. Compared with ordinary presses, metal pneumatic presses adopt advanced photoelectric protection technology. It is a press equipment that uses
pneumatic clutch brake type to realize the mutual cooperation of computer counting and programs, which greatly improves work efficiency.
The metal pneumatic punch is mainly composed of a body, a pneumatic clutch, a slider and a micro-control system.
1. Body: Cast into one body with the worktable. The slider moves up and down in the guide rail on the body of the metal pneumatic punch press. The gap between the guide rail
and the slider is adjusted by the top wire, and the cap is tightened after adjustment.
2. Clutch: adopts composite dry pneumatic clutch, flywheel built-in bearing and clutch, sealing plate is fixedly combined, when the start control button is pressed, the solenoid valve
will press air into the clutch, the power of the flywheel will be transmitted to the crankshaft to work, select the control panel kinetic energy The key can realize the continuous work
of the inching stroke.
3. Slider: The connecting rod and the ball head adjusting screw convert the circular motion of the crankshaft into reciprocating motion. The ball head screw can adjust the clamping
force and adjust the height of the mold. The lower end of the slider has a mold handle hole, which can be tightened during decoration. For solid molds, large molds can use the template
holes on both sides and the slider adjustment holes are equipped with a material ejection device. The ejector seats on both sides are adjusted according to the height of the mold to realize automatic material removal.
4. Operating mechanism: It is controlled by a microcomputer, and the status mode is displayed on the panel. When the status bar shows an inch movement, the machine can be
synchronized with both hands to realize a 360-degree stop at will. For sports, the synchronous start time is 0, 2-0, 3 seconds. When starting the stroke or continuous work, you must use inch kinetic energy to point the hour hand of the display to 12 o’clock, or observe the angle meter at 12 o’clock, plus or minus 20 degrees can be started; When working continuously,
you must press the start button with both hands to make the machine run continuously for 5-7 to achieve continuous work.
The working principle of metal pneumatic punch
The working principle of metal pneumatic punch:
1. The metal pneumatic punch press uses a pneumatic clutch to transmit the inertial force of the flywheel to the crankshaft, connecting rod, and slider. The working principle is
shown in the attached drawing; the crankshaft connecting rod is rigid, so the slider movement is mandatory. When the speed is the same , The number of strokes and movement
curve of the slider are fixed.
2. Using the high-pressure gas produced by the compressor, the compressed gas is delivered to the solenoid valve through the pipeline, and the action of the solenoid valve is
controlled by the foot switch to control the work and return of the cylinder, so as to achieve the purpose of punching.
3. The compressed air can be stored in the air storage tank and can be used at any time, so there is no waste of energy due to idling of the motor. Using the cylinder as the
working part and the solenoid valve as the control element make the structure of the machine simpler, the failure rate is low, the maintenance is simple, and the maintenance cost is lower.
Features of metal pneumatic punch
Features of metal pneumatic punch:
1. Compressed air is used as the power source, and it is easy to operate and simple in structure.
2. Using a microcomputer control system, the mode can be selected from manual, semi-automatic and fully automatic. Heating mold, temperature control and pressure sensor
can be added. Simple structure.
3. Equipped with anti-rotation guide rods and guide plates, with high precision, which can adapt to high-speed punching.
4. The height, speed, stroke, pressure and stamping time can be adjusted arbitrarily according to different products or molds.
5. There is no noise generated by the hydraulic system during standby, which can save power consumption and reduce production costs.
6. Two-hand control or foot pedal mode can be selected. Ensure the personal of the operator.
Application range of metal pneumatic punch
1. Metal punching industry: Metal pneumatic punching machines are widely used in metal punching industry, and can be applied to the punching field of various metal and
non-metal pipes and plates.
2. Machinery industry: applicable to the processing and production of stamping parts, stamping processing, metal stamping parts, metal stamping parts, automobile stamping
parts, drawing parts, metal drawing parts, and stamping sheet metal parts in the machinery industry.
3. Household products: most of the furniture products in daily life are processed and produced by metal pneumatic punches, such as electronics, communications, electrical appliances,
lighting, toys, chassis, furniture, sports equipment, barbecue tableware hardware, lighting hardware, electronic hardware , Chassis cabinets, kitchen utensils, hinges, split pins,
spring pins, pliers, dried fruit pliers, packaging materials, stickers, mobile phone films, gaskets, cushions, aluminum parts, terminals, speaker nets and other daily necessities.
4. Road traffic: In particular, the production of auto parts is inseparable from metal pneumatic punches, transportation supplies, protective equipment, automobiles and
motorcycles and accessories communication products.
5. Office supplies: power cabinets, ATM shells, air-conditioning parts, printers, copier racks and various sheet metal.
