| 3.Slider | |||||
| The movement of the slider is achieved by four vertical column guidance.The guide sleeve between slider and vertical column is alloy material with good abrasion resistance and easy replacement measures after abrasion.The below platform has equipped with T type slot to make the mold stable ,the detailed dimension can be provided under the requirement. | |||||
| 4.Lifting cylinder | |||||
| Lifting cylinder is a piston type cylinder equipped in the middle hold of the foundation to work for the top or drawing process. | |||||
| 5.Upright Column and lockout | |||||
| The material of upright column is 45# forged steel,and has process in drawing temper,the quenching hardness of the upright colume surface can reach HRC42-50.The material of Locknut is 45# forged steel,and has produced in blue handle,the connection between the upright colume and locknut is screw thread connection. | |||||
| 6.Stroke limit device | |||||
| The stroke limit device is equipped in the left side of the machine to control the stroke distance for the slider.It is composed by parallels,angle iron,induction block and contactless switch.Two parallels iron is fixed in the worktalbe and top rail to fix angle iron,there are guide groove in the angle iron ajust the travel switch and the stroke of the slider will be controlled. | |||||
| 7.Hydraulic pressure station | |||||
| The hydraulic pump is composed by fuel tank,axial plunger pump,motor,two way cartridge valve,oil filter and air cleaner. | |||||
| (1)The tanker is welded by Q235 Steel,the front end is equipped with a pressure gauge for a easy obersation of the pressure and pressure-adjustment.In the lower part of the bracket is equipped with a pressure gauge level gauge, to observe the level.Open the upper cover ,for fuel filling.In the fuel tank is provided with a cleaning mouth, open cover capable of cleaning the tank. | |||||
| (2)Fuel tank for the steel plate welded structure, by shot peening and rust prevention treatment,there are clean mouth in the side of tank and oil level ruler.The air clear,valve integrated blocks are in ordered arrangement in the top of tanker cover. | |||||
| (3)The main hydraulic piping with flange connection, with reasonable layout of the seismic pipe clamp to prevent pressure pipeline vibration and leakage.Before the pipeline installation,there will be process of pickling and passivation treatment to guarantee oil cleanliness. | |||||
| (4)Axial plunger pump The hydraulic system use YCY14-1B axial plunger pump,the main specification and instruction is included in the axial plunger pump manual. |
|||||
