Description
Technical Field
The utility model belongs to the field of machinery, a simple and easy dismouting device and dismouting method of large-scale hydraulic press punching cylinder are related to, are applicable to the use maintenance of hydraulic press punching cylinder.
Background
The core process of wheel rolling is that the wheel is preformed, formed, rolled and punched, the wheel punching is completed by a punching cylinder of a large-scale oil press, the punching cylinder is arranged in a main cylinder of the oil press, the operation power of the punching cylinder is provided by a high-pressure main pump, the operation displacement is controlled by a displacement encoder of the punching cylinder, the completion of the action of the punching cylinder is realized by transmitting the numerical value to a controller by the displacement encoder and controlling hydraulic control elements, and the movement of the punching cylinder is controlled in a closed loop mode by the mutual matching of the control elements, so that the punching cylinder can automatically and accurately complete the punching action.
The punching cylinder is used as an important part in the process of a wheel pressing system, the working pressure is high, the impact force is large, the working oil temperature is high, the sealing of the punching cylinder is continuously subjected to high-pressure impact and abrasion with the inner wall of the cylinder barrel in the frequent punching working process, and the sealing oil leakage of the punching cylinder can occur after the punching cylinder is used for a period of time due to the influence of high working temperature, so that the normal production cannot be realized, and the sealing of the punching cylinder must be stopped and replaced. In the process of replacing the sealing of the punching cylinder, the base plate installed below the punching cylinder is detached firstly, and because a hydraulic wrench does not have a reaction supporting point in the process of detaching a bolt of the base plate, the hydraulic wrench can only use a cushion block as the supporting point, the supporting point is easy to slide in the use process of the hydraulic wrench, so that the inner hexagon of the bolt is damaged, the bolt can not be taken out, the bolt can be cut off by a cutting knife, the part of the screw hole of the base plate can be damaged in the cutting process, and the replacement time is greatly prolonged. When repacking after sealed the changing of jar that punches a hole, just can install after having aligned the jar that punches a hole with the cylinder center, if there is the deviation in the center, can lead to the jar that punches a hole sealed by the extrusion damage, the oil leak once more appears, and then causes the rework. When the cushion plate is re-installed, the 12 screw holes on the cushion plate and the 12 screw holes on the main cylinder are completely aligned in center to install the bolts. Since the weight of the pad plate is 6.7 tons, the pad plate must be moved out of the adjusted position from below the master cylinder and then tried again each time there is a positional deviation, and the pad plate must be installed many times each time, resulting in a considerably prolonged replacement time. Therefore, the disassembling and assembling process requirements and the replacing process of the punching cylinder need to be analyzed and controlled, in order to reduce the replacing time, a simple disassembling and assembling device of the punching cylinder of the large-sized oil press needs to be designed, a perfect technical disassembling and assembling scheme is formulated to quickly replace the punching cylinder, in addition, the simple disassembling and assembling device not only needs to shorten the replacing time and reduce the damage to other workpieces, but also needs to ensure the disassembling and assembling process requirements of the punching cylinder.
