female swivel fitting Piston pump installed in the hydraulic oil

work order deduction of the machine 's hydraulic crimping machine
Deduction of the machine , female swivel fitting commonly called a crimping machine , crimping machine , is a method for crimping hydraulic hose fittings tube assembly of hydraulic equipment, which will be the supporting metal joint by crimping machine mold shrinkage force exerted by the hydraulic system, withhold solid metal joints on the supporting hydraulic tubing and rubber hose.
Tips
1 , the operating principle of dual hydraulic circuit , i.e., mouth and contraction of the piston forward and backward movement of the mold and the motive power of the hydraulic power source is generated . Not only does it move smoothly , return quickly , like a spring return , not open and lock the mold phenomenon does not occur. And all around the cylinder locking system design through easy to withhold various shaped elbow.
2 , the hydraulic system by the motor , pump , solenoid valve , relief valve and the hydraulic valve would move back and forth with a double hydraulic circuit , but also in a double hydraulic circuit of a rapid increase in drain oil from the valve passage , parher jic female swivel fitting in order to achieve more Quick return purposes, and the speed is adjustable , noise and system pressure is reduced.
3 , the electrical control system, the control circuit applies PLC circuit , it is easy to repair circuits , easy maintenance and replacement simple.
4 , mold and die holder withhold cumulative error -free machining process to ensure that the withholding of withholding product evenly spaced lines , no size head phenomenon .
5 , in order to withhold machine permanent mechanical precision and life on the locking mechanism assembly , not only chose the high-quality steel materials, and the use of a unique heat treatment process. So crimping machine long life : the selection, heat treatment, machining process and the reasonableness of the structure are inseparable !
6, for double-column crimping machine , C -type crimping machine easy to set up because they do not die positioning, numerical methods must be used to control withhold size.
7 , withhold standard
Theoretical requirements : not from the head , does not destroy the rubber hose
In order not to take off the head - withhold efforts should be large , in order not to destroy the glue - withhold efforts to be small. To resolve this conflict without crimping machine to choose the first taper ( 0 taper ) pressure pipe machine so that both ends of the front and rear hydraulic metal joints consistent data to avoid errors. ( Note: If the front metal joints compressed intensity is too large , will be crushed if the metal connector joints backend compression intensity is too large , the rubber hose will fracture , causing the hose leakage , etc. ) .
How to withhold a satisfactory hose
When the user when to withhold high-pressure pipe , if the withholding amount is too small , then the weight between the connector and the hose is too loose , the role of hydraulic hose withhold there may emerge from the joint in the initial period , if you withhold too large , then connector and hose too tight , easily lead to hose inner being localized damage, cracks , hydraulic oil directly into the steel layer from the rupture , and then he went along the gap between the wire coat tails oozing , or has been channeling along the wire layer to build up somewhere , so that the outer layer of plastic to produce drum kits and even rupture .
When withheld , nor withhold too fast, as is likely to cause damage to the rubber layer and wire breakage , so that the hose in use prematurely. Practical work , the replacement of the high-pressure hose, hose length selected , wire layers, joint shape and size to be reasonable , and should minimize the degree of bending of the hose , the majority of hydraulic hose assembly the damage is due to the high pressure hose making improper .
Works
Piston pump installed in the hydraulic oil in the tank immersed in silent cooling design to achieve scientific purposes , the motor driven piston pumps , hydraulic oil output , push the plunger movement withhold tanks , resulting in mold base radial contraction , and mold squeeze on the hose fitting jacket . When the contraction reached micrometer predetermined value , squeezing automatically stop solenoid valve to change back , reverse movement of the plunger within the cylinder , die along with open, withhold hose complete.
