Benefit and Application of Hydraulic Press Machine

The hydraulic press machine (also known as hydraulic oil press) is a machine that uses the static pressure of a liquid to process metal, plastic, rubber, wood and dust products.

It is ordinarily used in pressing and forming processes of pressing, stamping, cold extrusion, straightening, bending, beading, sheet drawing, powder metallurgy, pressure, etc.

Different types of hydraulic press machines are operating differently. And every Hydraulic Press Machine Manufacturer will provide an operation manual in conjunction with the hydraulic press when delivered. The manual will be the best training material for you to learn various important points about how to use hydraulic press.

Advantages of Hydraulic Press Machine

Compared to the traditional stamping process, the hydroforming process has obvious technical and economic advantages for reducing weight, reducing the number of parts and improving the volume, hardness and strength of the mold, reducing production costs, etc. More and more applications have been made the industrial sector, particularly in the automobile industry.

In the automotive industry, aviation, aerospace sectors, it is a long-term goal to reduce structural quality and save energy in operation. This is one of the development trends of advanced manufacturing technology.

Hydroforming is an advanced manufacturing technique for realizing lightweight structures.

Compared to stamping and welding techniques, hydraulic forming techniques have the following main advantages:

1. Lose Weight and Save Ingredients

For specific parts such as automobile engine mounts and radiator mounts, hydraulic shaping parts are 20% ~ 40% lighter than stamping parts. For hollow stepped shaft parts, the weight can be reduced by 40% ~ 50%.

2. Reduce the Number of Parts and Molds and Reduce the Cost of Molds

Hydraulic forming parts usually require only one set of molds, while most stamping parts require more sets of molds. Hydraulic forming engine bracket parts were reduced from 6 to 1, with radiator bracket parts reduced from 17 to 10.

3. Reduce Welding Of Subsequent Machining and Assembly

For example, take the radiator support, the heat dissipation area increased by 43%, the soldering point decreased from 174 to 20, the process decreased from 13 to 6 and productivity increased by 66%.

4. Improve Strength and Rigidity, Especially Fatigue Strength

For example, the stiffness of hydroformed radiator brackets can be increased by 39% in the vertical direction and 50% in the horizontal direction.

5. Lower Production Costs

According to the statistical analysis of the used hydraulic forming parts, the average production cost of the hydraulic forming parts is 15% ~ 20% less than that of the stamping parts and the mold cost is 20% ~ 30% less.

Application of Hydraulic Press Machine

Hydraulic Press Machine can be used for the process of drawing, turning, bending and stamping of metal sheet parts. It can also be used in general pressurized technology, in which buffering, blanking, moving table devices can be added according to user needs.

In addition to forging and forming, three-beam four-column hydraulic presses can also be used for correcting, press mounting, packing, briquetting, and plate pressing.

Materials suitable for the hydraulic forming process include carbon steel, stainless steel, aluminium alloys, copper alloys, and nickel alloys.

In principle, all materials decent for cold forming are suitable for the hydraulic forming process.

It is widely used in Automobile Parts Factory, Electronics Factory, Electric Equipment Factory, Heat Treatment Plant, Gear Factory, and Air Conditioning Parts Factory.

In addition, hydraulic forming techniques have been widely used in the automobile, aviation, aerospace and pipeline industries. This mainly applies to:

• Hollow structural parts with variable, rectangular or special-shaped sections along the axes of the components, such as special-shaped pipe parts of the exhaust system of automobiles;

• Non-circular hollow frames, such as engine brackets, instrument panel brackets, and body frames (accounting for 11% ~ 15% of vehicle quality);

• Hollow shaft parts and complex pipe fittings etc.
