| How to choose the design of the elbow machine correctly
When the correct choice of elbow machine, the first choice of elbow machine design.Elbow machine is a device for pushing and making elbow.It is mainly designed to solve the problem of large wall thickness difference of pressing elbow.It includes frame, intermediate frequency heater, hydraulic system, with fixed bed fixed to the frame of the back-end, fixed with a hole at the center of the machine, the oil cylinder is fixed on the fixed table, no bar and rod of oil cylinder cavity respectively through the pipe connected to the hydraulic system, have a haircut and the oil cylinder cylinder rod fixed contact, have a haircut central hole, intermediate frequency heater with heating coil wire connection,Wedge key hole is at the back of the core rod from the middle of the heating circle and have a haircut in the hole and the center of the fixed bed hole through the wedge key to wear in the key hole wedge core rod, activity semicircle card board is composed of upper and lower two semicircle card board, card board activity half of upper and lower two semicircle card board are installed on the surface before have a haircut at the same time set on the mandrel and with core rod gaps.The advantage is that the produced elbow wall thickness is uniform.The above is the main design of the customer in the choice of elbow machine.
The normal operation principle of elbow push machine
Elbow push machine main machine, hydraulic pump station, operation table, motor control cabinet, medium frequency power supply, water cable, medium frequency coil, reactor.When the elbow pushing machine is pushing the elbow, first of all, the cut raw materials are sheathe on the elbow mold rod, and the intermediate frequency induction wire snare is placed on the end of the elbow mold core. Then, the cooling water pump and the intermediate frequency power supply are started. When the raw materials are heated to the temperature of the hard top, the elbow pushing machine is started to push the elbow.According to the elbow to choose the main push pump, selected rate feeding, the gate, mandrel heating to a certain temperature began to advance, the heating speed is adjustable, pushed to the end of the push machine active stop, the hydraulic gate gate dead, mandrel feeding, loosen the gate retreat to the end, the gate gate to the outer diameter of the rod began to advance.Note: the main push pump can be used at the same time when working, the same environment usually only use one can.It can also be used to retreat without ceasing to stop.Retreat pump can not be used at the same time, can only start one, another standby.Feeding pump can only be used when feeding.Safety pressure positioning of the same system as the main oil pump.The travel switch is installed at both ends of the push machine travel, and the realistic travel should be less than the maximum travel, that is, the two ends of the movement push plate before and after leaving a margin from the realistic endpoint, so as to avoid the cylinder piston running to the end.The normal operation and working principle of elbow pushing machine.
