Classification of hydraulic press The difference between hydraulic press and hydraulic press

To be practical: the hydraulic press is to use the hydraulic pump to convert the hydraulic energy generated by the hydraulic oil into powerful mechanical energy to complete the work that cannot be completed by hand and is difficult to complete.

Common hydraulic presses in life: hydraulic presses, hydraulic balers, hydraulic straighteners, hydraulic shearing machines, die-casting machines, profile extruders (this belongs to the largest and most cumbersome hydraulic system in the non-ferrous metal industry, and I designed this.) Employers:

Wuxi Yuanchang Machinery Manufacturing ****, you can go to my company ** to see, thank you. )

Hydraulic press models include Y41 series single-row hydraulic press, Y27 series four-column hydraulic press, Y32 series four-column press.

Hydraulic press is a kind of mechanical equipment that uses liquid to transfer energy by pressure, and is widely used in various industrial fields. According to different use needs and working principles, there are various models of hydraulic presses. The hydraulic press adopts hydraulic transmission, which is stable and can ensure the stability and accuracy in the processing process.

The hydraulic press is flexible and can adjust the pressure and flow of the hydraulic system to meet different process requirements.

It should be noted that different types of hydraulic presses have different structures and working principles, which are suitable for different working occasions and workpiece processing. When choosing the model of hydraulic press, you need to choose according to the specific work needs, and choose the right product for yourself in combination with your own production process and requirements.

Precautions for purchasing hydraulic presses

1. Functional requirements: according to their own needs, choose the same type and specification of impure filial piety, such as manual hydraulic press, hydraulic hydraulic press, etc.

2. Pressure and flow: choose a hydraulic press that meets your own needs for pressure and flow, and different jobs need to have different pressure and flow requirements.

3. Brand and quality: choose well-known brands and guaranteed quality hydraulic presses, and avoid buying inferior products or hydraulic presses with quality problems.

4. Resistance to use: The material and structure of the hydraulic press should be firm and strong, with good durability and service life.

5. Safety: When purchasing a hydraulic press, you need to pay attention to its safety performance, such as whether it has safety measures such as overload protection and limit protection.

1. The hydraulic press is a kind of hydraulic press, the hydraulic press uses oil to transmit pressure, and there are many kinds of hydraulic presses, which can be used to transmit pressure with oil or water, and most hydraulic presses use oil.

2. Hydraulic press (a kind of hydraulic press) is a kind of special hydraulic oil as the working medium, through the hydraulic pump as the power source, relying on the force of the pump to make the hydraulic oil enter the cylinder piston through the hydraulic pipeline, and then the cylinder piston has several groups of seals that cooperate with each other, the seals in different positions are different, but they all play the role of sealing, so that the hydraulic oil can not leak. Ultimatum through the one-way valve to make the hydraulic oil circulate in the oil tank, so that the cylinder piston circulates to do work, so as to complete a certain mechanical action as a kind of machinery for productivity.

3. The hydraulic press is a kind of machine made of liquid as the working medium and made according to Pascal's principle to transfer energy to achieve various processes. The hydraulic press is generally composed of three parts: the machine (main engine), the power system and the hydraulic control system. Hydraulic presses are classified into valve rental Wang Fengmen hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses.

The hydraulic press is mainly composed of two parts: a complete hydraulic press composed of the main engine and the control system, the main engine includes: the fuselage, the ejection cylinder, the main cylinder and the composition of the liquid filling device, and the control system is mainly responsible for a power demand.

It is composed of a fuel tank, a low-pressure control system, a high-pressure pump, a motor, and various pressure valves and directional valves.

There are many categories of hydraulic press in the market, of course, its use is also diverse according to the needs of the market, such as hydraulic press and hydraulic press. Due to the large pressure of the hydraulic press, it is generally widely used in forging and stamping, and the first domestic manufacturing of more than 10,000 tons of hydraulic press is the free forging hydraulic press, and the free forging hydraulic press does not use moldsDie forging hydraulic press requires the use of molds.

Hydraulic presses can be roughly divided into these two types.

At present, the hydraulic press in the domestic market is mainly divided into four-column hydraulic press, horizontal hydraulic press and single-column hydraulic press according to the structural form. Main Applications:

It is mainly divided into metal forming hydraulic presses, bending hydraulic presses, stretching hydraulic presses, press-fitting hydraulic presses, extrusion hydraulic presses, etc., which are too many to list one by one, and are widely used in: electronics, home appliances, hardware, sports equipment, plastics, furniture, automobiles and many other industries, so to speak, almost all production industries have seen its figure.

There are many uses, for example, the stainless steel tea jar we usually use. This belongs to stretching, as well as the interior of our cars, brake pads, etc., most of which are pressed out by hydraulic presses, and some also need to be vulcanized and then pressed, so that the density is higher. All in all, it's very broad, it's just that we don't usually pay attention to it.

As for the principle, it's a little complicated, but let's talk about it! Through the hydraulic pump as the power source, the hydraulic oil is made to enter the cylinder piston through the hydraulic pipeline by the force of the pump. Hehe, these are also what I saw on the Internet.

Widely used in: electronics, computers, home appliances, hardware, stationery, locks, sports equipment, bicycles, plastics, furniture, automobiles and other industries. (Such as:.)

Motor assembly, shaft, bearing pressing, transformer shaping, electrical switch assembly, electronics, computer parts assembly, riveting, photo frame molding, plastic molding, cutting, printing trademarks, typing, steel pipe expansion molding, etc.).

Type of oil for hydraulic press:

Generally, according to the recommended model of the machine can be purchased, if there is no recommendation, it generally depends on the pressure of the hydraulic press, if the pressure is not large, you can use No. 32, otherwise, you should use No. 46 or No. 68 anti-wear hydraulic oil.

When choosing hydraulic oil, you must find a regular hydraulic oil manufacturer, and the following factors should be considered:

1. Suitable viscosity and good viscosity temperature characteristics.

Viscosity is the first factor to consider when choosing hydraulic oil, under the same working pressure, the blind viscosity is too high, the movement resistance of hydraulic components increases, the self-priming ability of the hydraulic pump decreases when the temperature rises, and the pressure drop and power loss of the pipeline increase; If the viscosity is too low, it will increase the volume loss of the hydraulic pump, increase the leakage in the grinding silver brother of the element, and make the oil film of the sliding part thinner, and the supporting capacity will be reduced.

2. Good lubricity (anti-wear).

Hydraulic systems have a large number of moving parts that need to be lubricated to prevent wear and tear on the relatively moving surfaces, especially for systems with higher pressures, and the wear resistance requirements of hydraulic oil are much higher.

Hydraulic press. 3. Good oxidation resistance.

Oxidation will also occur in the process of hydraulic oil in use, the acidic substances produced after the oxidation of hydraulic oil will increase the corrosiveness to the metal, and the sludge sediment produced will block the filter and small gaps, so that the hydraulic system does not work properly, so it is required to have good oxidation resistance.

4. Good shear stability.

Because when the hydraulic oil passes through the pump, valve throttle and gap, it has to undergo violent shear action, resulting in the molecular fracture of some macromolecular polymers in the oil, such as tackifiers, and turning into small molecules, so that the viscosity is reduced, and when the viscosity is reduced to a certain extent, the oil can not be used, so it is required to have good shear resistance.

5. Good anti-rust and anti-corrosion.

Hydraulic oil will inevitably come into contact with moisture and air during use, as well as the acidic substances produced after oxidation, which will rust and corrode the metal and affect the normal operation of the hydraulic system.

6. Good demulsification resistance and hydrolysis stability.

Hydraulic oil is subjected to hydraulic pumps and other components as water and condensate mixed in from different sources during operation.

7. Good anti-foaming and air release.

In the hydraulic oil tank, because the bubbles mixed in the oil circulate with the oil, not only will the pressure of the system be reduced, the lubrication conditions will deteriorate, but also will produce abnormal noise and vibration, in addition, the bubbles also increase the area of oil and air contact, accelerate the oxidation of the oil, so the hydraulic oil is required to have good anti-foaming and air release.

Agree with the statement on the second floor, the pressure establishment medium of the hydraulic press is hydraulic oil, and the pressure establishment medium of the hydraulic press is hydraulic oil and it is possible to use water, but at present, the use of water pressure is becoming less and less.

The hydraulic press uses oil to transmit pressure, and the hydraulic press uses oil or water to transmit pressure. Most hydraulic presses use oil.

Abstract:With liquid as the working medium, the machinery used to transmit energy made according to Pascal's principle is called hydraulic press, hydraulic press is a kind of hydraulic press, it uses hydraulic oil, compared with hydraulic press, the main working medium is different, the range of hydraulic press is wider, in addition to hydraulic oil, you can also use water, water-based emulsion, etc. as the medium. The hydraulic oil used in hydraulic presses is hydraulic mineral oil, which comes in a variety of viscosities and specifications.

Let's take a look at the difference between hydraulic press and hydraulic press. 1. Is the hydraulic press a hydraulic press?

There is only one word difference between hydraulic press and hydraulic press, and many friends will confuse it, in fact, hydraulic press is a kind of hydraulic press.

According to the official definition, a hydraulic press refers to a machine that uses liquid as the working medium and is used to transfer energy to achieve various processes according to Pascal's principle; Hydraulic press, as the name suggests, is a hydraulic press with oil as the working medium, and is the most commonly used type of hydraulic press.

2. What is the difference between hydraulic press and hydraulic press.

The hydraulic press belongs to the hydraulic press, and it is the relationship between it and the hydraulic press, if there is any difference, that is, the working medium is different.

In addition to hydraulic oil, the hydraulic press can also use water-based emulsion and water as the working medium, but because the performance of the oil is better and the cost is lower, it has become the most widely used hydraulic press.

3. What kind of oil is used in the hydraulic press?

The hydraulic press that uses hydraulic oil as the working medium is the oil book press, which does not use ordinary oil, but special hydraulic mineral oil.

Hydraulic machines use hydraulic oil, generally need to be selected according to the requirements of the equipment viscosity, etc.) and specifications (HL, HM, HV, etc.), the use of more HM (anti-wear hydraulic oil). There are many specifications of hydraulic oil, and the selection needs to be selected according to the use environment of hydraulic oil and engineering environmental conditions, and the temperature, environment, hydraulic system, working intensity, equipment material, economy and other judgments are considered.
