Mechanical structure and working principle of sheet metal pneumatic punch

What is the sheet metal pneumatic punching machine? The sheet metal pneumatic punching machine 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 punches, the sheet metal pneumatic punching machine adopts advanced

photoelectric protection technology. It uses pneumatic clutch brake type punching equipment to realize the mutual cooperation of computer counting and programs,

which greatly improves work efficiency.

The sheet metal pneumatic punching machine 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 machine body of the sheet metal pneumatic punching machine.
2. The gap between the guide rail and the slider is adjusted by the top wire, and the cap is tightened after adjustment.
3. Clutch: adopts composite dry pneumatic clutch, flywheel built-in bearing and clutch, sealing plate is fixedly combined, when the start control button is pressed,
4. 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
5. The key can realize the continuous work of the inching stroke.
6. 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
7. 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,
8. 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
9. adjusted according to the height of the mold to realize automatic material removal.
10. 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
11. 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
12. 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;
13. 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.

Working principle of sheet metal pneumatic punching machine

The working principle of sheet metal pneumatic punching machine:

1. The sheet metal pneumatic punching machine works by using a pneumatic clutch to transmit the inertial force of the flywheel to the crankshaft, connecting rod,
2. and sliding block. The working principle is shown in the attached drawings; the crankshaft connecting rod is rigid, so the movement of the sliding block is mandatory.
3. When rotating speed, the number of strokes and movement curve of the slider are fixed.
4. 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
5. is controlled by the foot switch to control the work and return of the cylinder, so as to achieve the purpose of punching.
6. 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
7. 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,
8. and the maintenance cost is lower.
