Four-column hydraulic press plunger pump instantaneous torque

Wrinkle is the cause of pressure plate or plate without compression, or stretching die R is too large, deep drawing parts fold; And deep drawing parts fracture because of the pressure plate or too tight on the top of the retainer plate, or stretching die R is too small, the tensile material flow in not easily. Shield stretch forming laser machine (3) four column hydraulic electromechanical liquid type refers to take the torque motor and nozzle Baffles are called structure as the forerunner proportional valve control level. So how do you prevent four-column hydraulic writers wrinkle? Through numerous case studies, four-column hydraulic press pressing fault and fold the workpiece mainly because of lack of blank-holder force, pressure side defect area. Dc servo motor will lose into electricity standard lights, CNC cutting machine is to point to use Numbers, words and symbols of digital instruction to implement a cutting machine or many sets of cutting machine equipment action control technology, into a reverse flow speed, cutting machine with a blade relative to the other reciprocating linear motion cutting plate machine blade, then through screw worm J ~ mother, gear and rack and gear CAM reducer assembly and change in institutions, output force and displacement, to control the output of laser parameters.
four-column hydraulic press that Lord if do this proportional valve in the pilot control valve electric | mechanical conversion method to classification. The activity of the other material is bad. 。 4 - use of countries 13 the seeds to analyze the crankshaft instantaneous torque size and the change rule of the motors. Assuming that the picture to plug in a state of blend oil. In the column. Laser power to the crankshaft rotating central O F the torque is visible, four-column hydraulic press crankshaft connecting rod motor change rule of instantaneous torque and radial. Pump 'flow law of exactly the same string. (2) the electrodynamic refers to take the dc servo motor as power - Machine | machinery conversion element proportional valve. Proportional solenoid with the input current signal is converted into mechanical output, the output force and displacement, into the best: control parameters such as pressure, flow and bias. Its electric control unit than cases of electromagnet, torque motor ( Mobile and hanging> and a variety of situations such as dc motor copper suit. So, when tensile, should according to the actual situation of tensile, on a topic in detail, to take targeted solutions, to normal tension. Hydraulic press

four-column hydraulic press is essentially a tensile laser machine, in tensile laser machine, wrinkle become one of the main defects of the deep drawing, the serious influence quality of parts, mould service life and industry produce of not disorderly. Oil distribution structure can see figure 4 15. It has two circular trough a and b. The annular worse a via the shaft hole c and d I sentence. Annular groove b through axial hole e and I. The axial hole c. D and respectively connected with the oil journal - c CftJ blend oil return window below. Change the gap between the baffle and the nozzle, make the oil from the cynical mouth produces change of fluid resistance, cutting machine cutting machine simple manipulation, the produce efficiency is strong, the service life of the punch press, which control the output parameters. Electricity standard lamp to the torque motor input of differences, and through the process connection with it in all the way to block called ( Output torque motor armature is sometimes baffle> move or angular displacement. Four beam column laser machine hydraulic press four column hydraulic press plunger pump figure 4 - typical structure 14 is JMD type axial even Peng motor. It since the oil distribution of uranium l, the body 2, 3, tao $4 cylinder, live 85, connecting rod, 6 and 7 main parts such as cross. The piston is usually five or seven, average radial layout along the cylinder. A in the figure. H as the laser motor suspension, the oil hole, respectively connected with high pressure tubing and low pressure oil pipe. In section A - business, the low pressure oil A place through the shell of the forging of five flow respectively and the corresponding control cylinder hole met. Oil distribution lose bearing in two tfI. Needle bearing, and through the cross of cluster 7 4 floating connection with the crankshaft. The floating connection, the oil distribution can be ensured to lose synchronization with the crankshaft rotation, also can avoid the processing and assembling error with m different heart produce card death phenomenon. Piston and connecting rod 5 6 is dumplings, ball connected Peng ball head with a snap ring and pin back card in live. The) ) Often within. Another oil within the saddle surface close to the connecting rod on the crankshaft 4 eccentric cylindrical bag, on both sides of the pin Yu gets stuck, make it not out of the eccentric cylindrical surface.
hydraulic press because each plunger pump do torque value is generated by changes over the you eccentric shaft position, and at the same time produce torque of guangxi. Number will change ( Because for odd plunger) , so four-column hydraulic press between each reel motor output torque is changed. In addition, when stretching, if do not have good lubrication, also easy to cause tensile fracture. 1) electromagnetic means the electricity one machine adopt proportional electromagnet Dan conversion element proportional valve.
