Advantages and Classification of Small Single Column Hydraulic Press


Compared with the traditional stamping die design, single-column hydraulic press has significant technical and economic development advantages in alleviating net weight, reducing the total number of parts and grinding wheels, improving bending stiffness and compression strength, and reducing product costs. It is used more and more in the industrial production industry, especially in the automobile industry. Then, let's learn about it together.Small single column hydraulic pressThe advantages and classification of it!

In the automotive industry, airlines, aerospace and other industries, relaxing the structural quality to save the kinetic energy in the use is the overall goal that everyone has pursued for a long time, and it is also one of the development trends of intelligent manufacturing technology. Hydraulic press forming is an intelligent manufacturing technology for completing lightweight structures.

  Small single column hydraulic pressStamping forming is also called "internal high stamping forming". It is the basic concept to take the tube as the blank, release the high-pressure liquid to the inside of the tube, and release the radial torque to both sides of the finishing tube, and expand the repair material. Under the interaction of the two external forces, the finish rolling tube blank is plastically deformed, and finally combined with the inner cavity of the grinding wheel forming mold, a hollow part with an appearance that meets the technical standards is obtained.

For hollow cross-section parts, in the existing production and manufacturing technology, two half blocks are formed by stamping dies and then formed into a whole by electric welding, while in hydraulic stamping, a special-shaped hollow part can be formed at one time along the cross-section of the preform. Compared with the welding method of stamping die, hydraulic stamping forming technology and processing technology have the following important advantages.

1) Relax quality and save raw materials. Compared with typical parts such as engine fixing bracket and heat pipe radiator support bracket, hydraulic press molding can relieve 20% ~ 40% of hollow stepping shaft parts and 40% ~ 50% of net weight relative to metal stamping parts.

2) Reduce the total number of parts and grinding wheels, and reduce the cost of grinding wheels. Hydraulic press molding products generally only need a set of grinding wheels, but most metal stamping parts need several sets of grinding wheels. Hydrostamped diesel engine fixing bracket parts were reduced from 6 to 1, and heat pipe radiator support bracket parts were reduced from 17 to 10.

3) It can reduce the amount of welding and welding for machining and assembly afterwards. Taking the heat pipe radiator bracket as an example, the total heat removal area is increased by 43%, the spot welding is reduced from 174 to 20, the process flow is reduced from 13 to 6, and the production efficiency is increased by 66%.

4) Improve the compression strength and bending rigidity, especially the fatigue limit. For example, a heat pipe radiator support bracket formed by a hydraulic press can increase the bending rigidity by 39% in the vertical direction and 50% in the horizontal direction.

5) Reduce product costs. The data analysis of the parts formed by hydraulic press shows that the product cost of the parts formed by hydraulic press is 15% ~ 20% lower than that of the metal stamping parts, and the cost of grinding wheel is 20% ~ 30% lower than that of the metal stamping parts.

  Small single column hydraulic pressClassification

  Small single column hydraulic pressAccording to the structure, it is divided into four column type, single column type (C type), vertical type, column type frame, hydraulic press, etc. According to the main purpose of different, can be divided into metal material forming, sheet metal bending, pull, cold pressing, powder (metal materials, non-metallic materials) forming, riveting, extrusion and so on. The general types are as follows: kind of hot forging single column hydraulic press: heavy forging single column hydraulic press is a kind of forging equipment that can carry out a variety of free casting technology, and is one of the widely used mechanical equipment in the field of forging. At this stage, there are 800T, 1600T, 2000T, 2500T, 3150T, 4000T, 5000T and other series of product specifications and models of gas-made monochrome column presses.

Small single-column hydraulic press: The single-column hydraulic press is applied to the processing technology of ductile blanks. For example, powder products forming, plastic products forming, hot and cold extrusion forming metal material forming, metal sheet extension and its transverse pressure, bending pressure, turning, alignment and other processing technologies. Single column hydraulic press can be divided into four column double beam single column hydraulic press, four column three beam single column hydraulic press, four column four beam single column hydraulic press.
