How rodless cylinders and common cylinders work Both sides of the cylinder are hollow, and the permanent magnet in the piston rod drives another magnet (moving part) outside the piston rod. I would like to say that it requires very high cleanliness. The rodless cylinder of our company's magnetic couple often To remove gasoline cleaning, it may be related to its work environment. The working principle of rodless cylinders and ordinary cylinders Rodless cylinders are divided into magnetic rodless cylinders and mechanical contactless rodless cylinders. Rodless cylinder refers to a cylinder that uses a piston to directly or indirectly connect with the outside world, and makes it follow the reciprocating cylinder of the piston. The biggest advantage of this type of cylinder is that it saves installation space. The working principle of rodless cylinder and common cylinder A sheet metal stamping operation is one in which sheet metal is cut and formed into a desired shape or profile. Although a sheet metal stamping process may utilize numerous types of special machines, three basic items are essential: the sheet metal from which the part is to be made; the stamping press; and the stamping die.
With the exception of a specialized sheet metal stamping process commonly referred to as hot stamping, most sheet metal stamping operations involve cold forming. This essentially means that no heat is intentionally introduced into the die or the sheet material. However, keep in mind that although stamping is a cold-forming process, heat is generated. Cutting or forming sheet metal creates friction between the die and the metal-much like the friction and heat that occur when you rub your hands together.

Rodless cylinders have pistons. Without piston rods, the pistons are in the guide rails. External loads connect the pistons and act on the intake air.
The magnetic coupling type motion is realized by using a permanent magnet in the hollow piston rod to drive another magnet outside the piston rod. Because it is fast and the load is high, the inner and outer magnetic rings are easy to disengage, so it is less used now. The size of its load quality needs to find its quality and speed characteristic curve. Now mechanical use is more.
(1) Magnetic couple rodless cylinder:
The piston moves the moving body outside the cylinder by magnetic force to make synchronous movement. Its working principle: a set of high-magnetism permanent magnetic rings are installed on the piston, and the magnetic force lines act through a thin-walled cylinder tube and another set of magnetic rings on the outside. Because the two sets of magnetic rings have opposite magnetic properties, they have strong suction. When the piston is pushed by the air pressure in the cylinder, the magnetic collar outside the cylinder moves together under the action of the magnetic force. The thrust of the cylinder piston must be compatible with the suction of the magnetic ring.
(2) Mechanical contactless rodless cylinders:
A slot is formed in the axial direction of the cylinder tube, and the piston and the upper part move along the upper part of the groove. In order to prevent leakage and dust, stainless steel band seals and dust-proof stainless steel belts are used to fasten the ends of the cylinder heads at the openings. The piston frame passes through the groove to integrate the piston with Shangzhi. Pistons are connected with Hisashi, driving the actuators fixed on Hisashi to achieve reciprocating motion.
Features:
1, compared with the ordinary cylinder, in the same trip can be reduced by 1/2 installation device;
2, no need to set up anti-rotation machinery;
3, suitable for bore diameter 10-80mm, maximum stroke up to 41.5m;
4, speed 10m/s
1, poor sealing performance, prone to leakage. When using a three-position valve must be selected medium pressure;
2. Due to the small load, in order to increase the load capacity, it is necessary to increase the guiding machinery.
Rodless cylinder brand: The rodless cylinders currently circulated on the market mainly include ORIGA rodless cylinders, Norgren rodless cylinders, FESTO rodless cylinders, SMC rodless cylinders, Koganei, etc. These brands are still good. ORIGA's product line is relatively small, is a professional rodless cylinder, but also the inventor of the rodless cylinder, with a patented metal sealing technology, but the overall visibility is sometimes inferior to several other.
