Continuous Lead Sheathing Extruder Type YQL100/5
1. Application
The continuous lead sheathing extruder typeYQL100/5 is designed with innovation to compound lead sheath over small cables or mineral cables, which is integrated with the advanced experience in the domestic and abroad same kind of machine
The machine performs continuous extrusion of lead with the vertical rotation of a screw to transit the lead upward, which is able to ensure equal thickness of lead on the longitudinal line of the lead pipe. Due to the strict control of temperature on each part, the extruding pressure and temperature can remain constant so that it is possible to keep the difference in lead thickness within a minimum.
As the melting & holding pot and the liquefied lead conveyed are enclosed, vaporization from lead can be greatly reduced. Therefore this extruder basically does not cause pollution to the environment.
This extruder is light in weight, and involves low labor intensity in operation, and takes a comparatively small area.
The extruder extrudes pure lead or alloy lead, and the ideal composition of alloy lead is as follows:
m | ||
2.1 | Pure lead | Pb-99.99% |
2.2 | Lead-antimony alloy | Sb-0.3-0.4% |
2.3 | Lead-stannum-antimony alloy | Sn-0.4%; Sb-0.2% |
2.4 | Lead-antimony-copper alloy | Sb-0.4%; Cu-0.04% |
2.5 | Lead-stannum-cadmium alloy | Sn-0.2%; Cd-0.075% |

5.4. ΩPipe
It is used to transfer lead between the melting pot and the purifying & holding pot, and between the purifying and holding pot and the extruding machine.
The lead transfer pipe is shaped like Ω Because it expands due to heating while the molten lead is heated in the holding pot and lead transfer pipe .
Material of Ω pipe is molded with seamless steel tube with good quality and without crack lines; at external Ω pipe is wrapped with the special heaters for heating, which has equal and good heat conductivity, moreover, the heating unit is not easily damaged, meanwhile at two ends of Ω pipe are mounted two temperature checking points, in which temperature checking thermal couples are set
On top of Ω pipe is mounted an additional manual temperature checking point to revise temperature
At the lead inlet entry to the host extruding machine, there is a stearic container so that it can satisfy processing requirements that cleans up the impurity etc. in the pipe during production

Gear box of extruder is of horizontal structure with leakage proof treatment, motor is connected with spiral bevel gear, the other gears is forged with alloy steel and cast steel and manufactured with fine finish rolling
Extruding screw conveys the lead vertically, which reduces effects of lead layer gravity
Axial die adjusting and die unloading at the entry of die are from the electric hydraulic station, which is convenient to adjust the thickness of lead layer and replace the die stock and die tip.
Equality of thickness of lead pipe is achieved with the 4 screws to adjust the die cover.
At the exit of die is mounted a special spraying unit to supply for the cooling and crystallization of lead layer.
5.6.Gear Lubricant Oil System
The gear box is oil stored tank, its whole structure for the machine is reasonable and compact.
The lubricant oil line consists of oil pump, filter, dual coolers, pressure gauge, etc. additionally is mounted pressure relay to supervise the lubricant oil line so that it can automatically alarm due to lack of oil. It saves maintenance time and ensures to resume production because of oil supply by pump
Lubricant oil enters into the gear box in 5 lines and spray lubricant oil on contact points of gears and each bearing
5.7.Internal Water circulating & Cooling System
Internal cooling water tank for the machine is under the ground , that is , it is at the bottom of host machine, consists of cooling water pump, safety valve, level controller, 8m2 heat exchanger , etc. which is to cooling each section of extruding barrel .
Clean soft water is pumped in from the entry of water tank(the water hardness is less than 4~5°dh, advise to use the distilled water )
On water tank is mounted level display meter for checking the water level in it, additionally equipped with the temperature sensor, flow regulator, pressure relay for supervising the internal cooling water system, it will automatically alarm due to surpassing set temperature or lack of water.
It saves maintenance time and ensure to resume production because of water supply by pump.
Soft water in water tank is transmitted to the upper, middle, lower heating zones of extruding barrel in 3 lines so that it can adjust the temperature of extruded lead, and its flow can be adjusted through valve according to the work state, and cooling water can be recycled for use after it is out of machine body and back to water tank
External cooling water supply for the machine is filtered drink water, which is provided by users, and its flow is 5t/h, temperature is less than 25℃, pressure is 0.3Mpa. After being filter, the external cooling water enters into the plate type heat exchanger to exchange heat with internal recycling cooling water, in addition it goes through the gear oil cooler, rear cooling unit, water cooling jacket of die stock for cooling.
5.8.Rear Water Cooling System
It consists of cooling water spraying pipe and subsequent spraying pipe for stainless steel laundry , which can make the second cooling for the crystallization of lead layer and crystallized lead sheath at the exit of die.
At the rear of laundry is mounted air compressed wiper to dry the surface of lead sheath.
5.9. Flow Controller (including full automatic auxiliary system)
The cooling water pumped out of the bottom of the machine enters into the extruding barrel in 3 lines through 3 glass rotameters in coordination with the heaters, inlet water is adjusted by manual which can control the process temperature of extruding barrel.
