The Mechanical type and equipment characteristics of four column hydraulic machine
Four column hydraulic machine is a mechanical device static pressure hydraulic oil pump to use metal processing, plastics, rubber, wood, powder and other products. It is used in pressing technology and forming process, such as: forging, stamping, bending, flanging, Leng Ji, straightening, sheet metal drawing, powder metallurgy, pressing etc.. Its principle is the use of liquid pressure transmission machinery based on Pascal's law made, there are many kinds of. Of course, also according to need is varied. As a kind of liquid transferring the pressure points, a hydraulic press and hydraulic press two categories.
Machinery categoryFour column hydraulic machine is the use of liquid pressure transmission machinery based on Pascal's law made, there are many kinds of. Of course, also according to need is varied. As a kind of liquid transferring the pressure points, a hydraulic press and hydraulic press two categories. The total pressure of hydraulic press machine to produce larger, commonly used in the forging and stamping. Hydraulic forging press is divided again for forging hydraulic press and free forging hydraulic press two. Die forging hydraulic press to die, but not die free forging hydraulic press. Our country makes the first 10000 ton hydraulic press is free forging hydraulic press. Four column hydraulic machine is composed by two parts of mainframe and control system.
Hydraulic machine part comprises a hydraulic cylinder, beam, column and liquid filling device. The power mechanism comprises an oil tank, a high-pressure pump, motor, control system, pressure control valve, directional valve. Pressing process of the hydraulic machine is applicable to the plasticity material. Such as powder molding, plastic molding, cold (hot) extrusion of metal forming, sheet tensile and transverse compression, bending, turning, calibration process. Four column hydraulic machine is an independent body and the electrical power system, the centralized control buttons, can realize the adjustment, manual and semi - automatic three kinds of mode of operation.
Equipment characteristicsThe machine is an independent body and the electrical power system, the centralized control buttons, can realize the adjustment, manual and semi - automatic three work modes: machine working pressure, pressing speed, idle fast downlink and reduction of travel and range, can be adjusted according to the process requirements, and can complete the ejection process, with the top process, drawing three processes, each process also is the constant pressure, constant distance two craft movements for choice, constant pressure molding process after the suppression with ejection delay and automatic return.
Dynamic organization of independent and electrical system, and the centralized control buttons, can complete the adjustment and automatic two kinds of operation method. Mobile working platform which is driven by a frequency controller, the electrical use the world leading PLC programmable controller. After the YH25 315D "T" shape and motion industry drawing production innovation, automation to improve the series hydraulic machine, advanced production power, the labor intensity is decreased operating personnel.
To liquid as the medium to transmit energy, the use of advanced composite cylinder hydraulic circuit, low oil temperature, air speed in 10MM/ seconds, feeding speed of 20 MM/ sec, equipment standby, sliding fast moves up and down noise less than 75 decibels, adopts four-column.three-plate structure, the movable plate vertical accuracy by four precise guide sleeves control, parallel precision under the working surface and the working surface of arbitrary point less than 0.08MM.
1.Weight, material saving. For the typical parts of automobile engine carrier, radiator bracket, hydroforming parts than stampig reduce 20%? 40%, the hollow shaft parts, can reduce the weight of 40% 50%.
2.To reduce the number of parts and molds to reduce the mold cost. Hydroforming parts usually only need 1 sets of mould and stamping parts, mostly to multiple sets of molds. Engine bracket parts hydroforming was reduced from 6 to 1, the radiator bracket parts was reduced from 17 to 10.
3.Can reduce the amount of welding subsequent machining and assembly. The radiator frame as the example, the radiating area increased by 43%, the solder joint was reduced from 174 to 20? Step by 13 reduced to 6, productivity increased by 66%.
4.To improve the strength and stiffness, especially the fatigue strength, such as the radiator frame hydroforming, the stiffness in the vertical direction can be increased by 39%, the horizontal direction can be increased by 50%.
5.To reduce the production cost. Based on the analysis of statistics has been used hydraulic forming parts, hydraulic parts to reduce production costs than the average 15% stamping? 20%, reduce the cost of mold 20%~30%.
