ZGX40D High Pot Lead Acid Battery
Grid Casting Machine
1 The application of ZGX40D Grid Casting Machine
As a special equipment to produce the lead calcium grid of lead-acid a ccumulator, ZGX40D casting machine has the advantages of consumption saving, reasonable structure, convenient operation, easy maintenance, wide production scope, reliable running etc. The machine contains the parts:
Lead melting furnace 1set
Lead feeding system 1set
Circulating water cooling system 1set
Electric control system 1set
Main casting machine 1set
2 Main technical parameters
2.1 Main casting machine:
(1)Engine model: Y90L-4 Power: N=1.5KW Speed: N=1400r/minute
(2)Grid-casting productivity: 6—17 big pieces/minute
lead-antimony alloy: Sb0.5~3%
lead-calcium alloy: Ca0.09~0.1%
(3)Max casting dimensions: Width400×Height(110~165)×Thickness(1.2~4.0)mm3
(5)Biggest air pressure of pipes: g=0.7MP
Pressure when closing moulds: P=1800N(calculated per 0.4MAa)
(6) Temperature of molds: upper mould 150~170°C lower mould170~190°C
2.2 Lead melting furnace(top position)
(1)Volume of lead melting furnance: 150L (1000Kg)
(2)Temperature of lead liquid: 430~520°C(can be adjusted)
Work fluctuating scope: ±10°C
(3)The furnace is heated by electro heat pipe:
max heating power: Nmax=18KW
working average power: Naverage=12KW
(4) The weight of lead melting furnace(after lead adding):2300Kg
2.3 Lead feeding system: top lead feeding system,fix pressure, ration lead feeding, flowing
automatically and heat preservation.
2.4 Circulating tank: mould and cutter circulating cool
3 Structure of main machine and working principal:
3.1 All other drive of main machine adopt mechanical drive except the opening and closing of molds and ration lead feeding be air-driven.
3.2 Temperature control of grid moulds: The moulds’ temperature is controlled by its electric heating plate. The heat meter will test the moulds’ temperature and let the temperature reliable relative stability.
3.3 Pneumatic principal: the open and close of moulds and ration lead feeding are controlled by air cylinder.
3.4The speed of main machine adopt frequency transformer to realize variable speed.
3.5Electric control system combine the former electric control cabinet of main machine and lead melting furnace as a whole and adopt PLC programmable controller to realize concentrated programming systematically and automatically and control for easy operation and maintenance.
