Pneumatic Air Shaft

The gas rise shaft is a special type of winding, expansion shaft, inflation shaft, air expansion roller, inflation shaft, pressure shaft and the like. The inflation shaft and the inflatable sleeve are extremely convenient to use.
Classification: The inflation axis is divided into a key type air expansion shaft, a plate type air expansion shaft, a round point air expansion shaft, an aluminum alloy air expansion shaft, and a gas nail shaft.

1. Inflatable operation time is short: the separation and placement of the inflation shaft and the paper tube can complete the inflation and deflation in just 3 seconds, and it does not need to disassemble any parts on the shaft end side to be tightly engaged with the paper tube.
2, paper tube placement is simple: in the action of inflation and deflation, can move and fix the paper tube at any position on the shaft surface.
3, the bearing weight is large: according to the actual needs of customers, to determine the size of the shaft diameter, and the use of high-hard steel, so that its load bearing increased.
4. High economic efficiency: The design of the shaft is a special function, which can be applied to all kinds of paper tubes of thick, thin, wide and narrow.
5, simple maintenance, long use time: Although the inflatable shaft is a mechanical accessory, but each part of its own structure has a fixed specification, can be used interchangeably, making it easy to maintain.

There are 1 inch, 1.5 inch, 2 inch, 2.5 inch, 3 inch, 6 inch, 8 inch, 10 inch, 12 inch, gas rise sets, etc., according to customer needs processing and production of different specifications of the gas rise axis.

Technique parameter

Pneumatic air shaft classification
1. Metal expansion key Air expansion shaft: There are pneumatic or mechanical expansion modes to choose from. The metal expansion key air expansion shaft can be used in the manufacturing and processing applications of most products. This steel serrated ear bulge prevents slippage during high acceleration and deceleration take-up and minimizes vibration during high speed operation.

2, expansion button expansion key: full-featured, low cost, high-efficiency take-up performance in a variety of applications, its tensioning element in the shape of a round button, very popular in the market.

3. Non-metallic expansion keys: These lightweight air expansion shafts are an economical choice for light loads and standard load applications. The non-metallic expansion key inflation shaft uses the molded rubber expansion key as the tensioning original.

Mechanical maintenance
(1) Neat: tools, workpieces, and accessories are placed neatly; safety protection devices are complete; line piping is complete.
(2) Cleaning: The inside and outside of the equipment are clean; all sliding surfaces and screws, gears, racks, etc. are free of oil and dirt; no leakage, no leakage, no leakage, no leakage; cleaning of the chips.
(3) Lubrication: Oil is changed on time, oil quality meets the requirements; oil pot, oil gun, oil cup, linoleum, oil line are clean and complete, the oil mark is bright, and the oil path is smooth. [4]
(4) Safety: Implement the system of fixed and fixed shifts; be familiar with the structure of the equipment and observe the operating procedures, use the equipment reasonably, carefully maintain the equipment, and prevent accidents.
Abnormal operation test
The purpose of the abnormal operation test is to improve system reliability and avoid undue accidents as much as possible. The abnormal operation test can be carried out as follows:
1 External sudden power failure experiment. When the device is operated manually or automatically, no matter under any circumstances, the sudden power-off of the external can be reliably stopped, and the device can be restored to normal operation by the specified operation steps.
2 emergency breaking test. When the device is running manually or automatically, no matter what the circumstances, for emergency disconnection operation (such as pressing the emergency stop button on the control panel), the device can be reliably stopped and the normal operation can be resumed through the specified operation steps. .
3 detection switch failure test. Consideration should be given to the possibility of system detection switch failure, especially for components that are prone to collision, interference, and safety of mechanical components, and abnormal tests should be performed on signals such as end-of-stroke detection. It must be ensured that even if a certain detection switch is defective or damaged, it still does not. A safety incident will occur.
4 Execution component failure test. Consideration should be given to the possibility of system actuators being defective, especially for actuators that are prone to mechanical collisions, interference, and affect safety. Anomaly tests should be performed to ensure that even if an actuator is defective or damaged, no safety accident will occur. .
5 protection circuit action test. The possibility of the protection circuit of the system should be considered. Especially for protection devices such as circuit breakers and automatic switches, it should be tested abnormally. It must be ensured that the device can be reliably stopped when the protection device is operated, and the specified operation steps can be used. Resume normal work.
