Hydraulic cylinders are used in plunger and drive type presses. By diameter, modifications vary. It is also important to note that most models have hinges. If we consider devices for plunger modifications, then they use special sleeves.
Directly onlays are made of honed steel. If we talk about hydraulic cylinders for drive presses, then they have pistons of various diameters. The lower part of the stem of the models is made with internal or external thread. It costs an average high-quality hydraulic cylinder in the region of 7 thousand rubles.
DIY model
An experienced milling machine operator can make a hydraulic cylinder on his own. The press (homemade), as a rule, is designed for a small load, therefore, a piston of small diameter is selected primarily for assembly. Then a trunnion is welded to it.
In order for the pad to be held, sleeves are used. Next, to make a hydraulic cylinder for the press with your own hands, you need a sleeve. It should be mounted behind the piston. On average, the stem diameter is 60 mm. If we consider modifications to drive presses, then special bonks are soldered at the end of the cylinders.
20 ton devices
Hydraulic cylinders of this type are manufactured for both plunger and drive presses. Pistons are installed with a diameter of up to 50 mm. Directly cylinders are made of heat-resistant steel. Some configurations have a special seal. The trunnion thickness in this case depends on the width of the piston. Hinges for such models are suitable for spherical type. Some models have an intermediate stop. On average, such a hydraulic cylinder costs about 7 thousand rubles.
30 ton models
Hydraulic cylinders for a press of 30 tons are in demand at industrial enterprises for stamping various dishes. Pistons for many models are of the damped type. The stem is installed directly with a diameter of about 60 mm. This type of hydraulic cylinder weighs around 22 kg. The stem is used without mounting. Modifications for drive presses have a sleeve. In diameter, it fits under the piston. Flanges in all configurations are mounted on special paws. It is also important to note that hydraulic cylinders without trunnion are on the market. The linings are made of honed steel. You can buy a model in stores at a price of 5 thousand rubles.
Welded Rod Devices
Hydraulic cylinders for a press of this type are made of small diameter. Pistons for models are usually designed for 20 tons. Some configurations use screw cylinders. It is also important to note that there are modifications with bonuses on the market. They are located at an angle of 90 degrees. The average weight of a hydraulic cylinder and a press pump of this type is around 20 kg, and it costs about 7 thousand rubles.
Wide flange application
Hydraulic cylinders with wide flanges are in demand in print media. On average, they are designed for 30 tons. In this case, the rods are made of heat-resistant steel. For some modifications, the piston is mounted a large diameter. It is also important to note that there are hydraulic cylinders that have a protective sleeve. Such devices weigh within 25 kg.
Sleeves for all models are located under the stock. The flanges are mounted directly in the sleeve. Seals in devices are used with special paws. Axles in almost all versions are missing. Nowadays, there are high-quality hydraulic cylinders in the region of 8 thousand rubles.
Models "Miol"
Hydraulic cylinders of this series are designed for a load of 25 tons. The piston of this model is 50 mm in diameter. The rod in the device is used welded type. If you believe the owners, the piston stroke of the hydraulic cylinder is not more than 70 mm. The booms in the presented device are located at a slight angle. Directly the cylinder is applied damped type.
Due to the special coating, the piston is able to withstand high temperatures. To date, these models are often installed on drive presses. The user is able to buy a hydraulic cylinder for a press (hydraulic) at a price of 5 thousand rubles.
Characteristics of the Torin model
These hydraulic cylinders for the press are able to withstand a load of up to 20 tons. If you believe the owners, the pistons wear out very rarely. However, it should be noted that the rod in the device is installed damped type. Bonks in this model are located at an angle of 50 degrees. The cylinder is used as a standard honed type. The overlay under the sleeve in the presented model is missing.
If you believe the reviews of the owners, then for hydraulic presses this hydraulic cylinder is not suitable. It is also important to note that the model quickly erases the flange. Its thickness is 2.3 mm. It is installed immediately above the seal. According to the documentation, the piston diameter is 55 mm. Hinges for this model are missing. The user is able to buy the specified hydraulic cylinder at a price of 6 thousand rubles.
Opinions about the models "TS"
These press hydraulic cylinders are only available with steel pistons. At the same time, the pads have a high temperature type. All this indicates a small wear of the product. It is also important to note that the device is able to withstand heavy loads. According to the owners, the model can be installed on presses with a load of up to 20 tons.
There are two seals in the device. The overlay in it will apply a damped type. The cylinder itself is mounted above the liner. If you believe the reviews, it is rarely deformed. The flange in the device is set to a small width. The sleeve is standardly used with a mount. The eye in this case is missing. The user can buy the presented hydraulic cylinder for a manual press at a price of 8 thousand rubles.
Reviews of hydraulic cylinders "Line"
The specified hydraulic cylinder receives positive feedback from consumers. In this case, the piston stroke is at 66 mm. The gasket itself is used of a small thickness, but it wears out slowly. According to the owners, the sleeve in the device is durable. The maximum load that it can withstand is 30 tons.
The overlay for this model is made with a heat-resistant layer. The cylinder is standardly applied damped type. Bonks in this model are at a slight angle. According to the documentation for the device, the specified hydraulic cylinder has two flanges. One of them is located at the base of the sleeve. The other flange is located at the piston itself. The hinges of this model are used spherical type. The stem of the model is mounted on a special mount.
The pin in the device is installed small. The total mass of this hydraulic cylinder is 33 kg. The specified modification is suitable only for drive presses. In this case, the piston diameter is 54 mm. Buy a hydraulic cylinder user modet at a price of 11 thousand rubles.
