Hydraulic press machine, also known as hydraulic power press machine, is a machine that uses hydrostatic pressure to process metal, plastic, rubber, wood, powder and other products. It is commonly used in the pressing process and the forming process, such as: forging, stamping, cold extrusion, straightening, bending, flanging, sheet drawing, powder metallurgy, pressing, etc.
According to the structure form, it is mainly divided into four-column type, single-column type (C type), horizontal type, vertical frame, universal hydraulic machine, etc.
According to usage, it is mainly divided into metal forming, bending, stretching, punching, powder (metal, non-metal) forming, pressing, and extrusion.
The large forging hydraulic press machine for sale is forging equipment that can complete various free forging processes and is one of the most widely used equipment in the forging industry. At present, there are forging industrial hydraulic presses of 800T, 1600T, 2000T, 2500T, 3150T, 4000T, 5000T, and other specifications.
The hydraulic power press machine is suitable for the pressing process of plastic materials, such as powder product molding, plastic product molding, cold (hot) extrusion metal molding, sheet stretching, as well as transverse pressure, bending pressure, turning, correction and other processes. The four-column hydraulic press machine for sale can be divided into a four-column two-beam hydraulic press, four-post three-beam hydraulic press, four-post four-beam hydraulic press, etc.
The single-column hydraulic press machine is also called a single-arm hydraulic power press machine. It can expand the working range, use three sides of the space, lengthen the stroke of the hydraulic cylinder (optional), the maximum expansion and contraction 260mm-800mm. Moreover, the hydraulic press machine for sale has a hydraulic system cooling device and can preset the working pressure.
This series of products are suitable for the pressing and fitting of various parts, bending and shaping, embossing and indentation, flanging, punching, and shallow drawing of small parts and the molding process of metal powder products. Double column hydraulic press machine adopts electric control, with a jog and semi-automatic circulation, can keep pressure delay and has good slider guidance, easy operation, easy maintenance, economic and durable. According to the user's needs, the hydraulic power press machine can add additional functions such as thermal instruments, ejector cylinders, stroke digital display, and counting.
The machine parts can be assembled, disassembled, straightened, calendered, stretched, bent, punched, etc. by hydraulic press machine, truly achieving one machine with multiple uses. The working table of the hydraulic press machine for sale can move up and down, the size expands the opening and closing height of the machine, and the use is more convenient.
For hollow variable cross-section structural parts, the traditional manufacturing process is to stamp and form two halves, and then weld them into a whole. However, the hydroforming can form a hollow structural part with a change in cross-section along the component in one piece. Compared with the stamping and welding process, the hydroforming technology and process have the following main advantages:
For typical parts such as automobile engine brackets and radiator brackets, the weight of hydroformed parts can be reduced by 20% to 40% compared to stamping parts. For hollow stepped shaft parts, the weight can be reduced by 40% to 50%.
Hydroformed parts usually only need one set of molds, while stamping parts usually require multiple sets of molds. The number of hydroformed engine bracket parts was reduced from 6 to 1, and the number of radiator bracket parts was reduced from 17 to 10.
Taking the radiator bracket as an example, the heat dissipation area is increased by 43%, the number of solder joints is reduced from 174 to 20, the process is reduced from 13 to 6, and the productivity is increased by 66%.
It can improve strength and stiffness, especially fatigue strength, such as a hydroformed radiator bracket. Its stiffness can be increased by 39% in the vertical direction and 50% in the horizontal direction.
According to the statistical analysis of the hydroforming parts that have been applied, the production cost of hydroforming parts is reduced by an average of 15% to 20% compared with stamping parts, and the mold cost is reduced by 20% to 30%.
The hydraulic press machine has a wide range of applications in the automotive, aerospace, aerospace, and pipeline industries. It is mainly applicable to round, rectangular, or shaped cross-section hollow structural parts that vary along the axis of the component, such as automobile exhaust system shaped pipes; non-circular cross-section Hollow frames, such as engine brackets, instrument panel brackets, and body frames (approximately 11% to 15% of the mass of the car); hollow shaft parts and complex pipe parts, etc.
Suitable materials for hydraulic power press machines include carbon steel, stainless steel, aluminum alloy, copper alloy, and nickel alloy, etc. In principle, materials suitable for cold forming are all suitable for hydraulic press machine. The hydraulic press machine for sale is mainly aimed at auto parts factory, electronics factory, electrical appliance factory, heat treatment factory, vehicle parts factory, gear factory, air conditioning parts factory.
