Advantages of cold pressing lead terminals
It belongs to the high-end lead parts products, the terminal is with anti-rotation design, the terminals are bright, with high compactness, can effectively prevent the terminal from acid climbing, completely eliminate the internal bubbles of the terminals. The finished terminals pass the baking testing, air hole corrosion testing, torsion testing, compactness testing, which are up to the qualified standards, the product quality is in the international leading level.
The lead terminal adopts the way of cold pressing, which solves the defects of the terminal such as crack, internal air hole, sand hole, etc., greatly eliminates the problem of acid crawling and terminal corrosion, and prolongs the service life of the battery.
Process for Making the Cold Forging Lead part
Lead part made by Gravity casting → Cold forging → Edge Trimming → Groove reversing
1. Automatic Gravity Casting Machine
Production Capacity: 3~4pcs/mold (one pot one machine); 6~8molds/min (one pot one machine);
2. High Precision Cold Pressing Machine
The cold pressing mold is the core for making the cold pressing product;
Pressing machine is customized according to the technical requirement (stroke, pressure and speed is specially customized); Double press start button, with safety light curtain protection (to protect the operator).
Product ejection: the ejection device is used to eject the product, and then take it out manually
It's designed to trim 2pcs/time (14~18pcs/min)
3. Trimming Machine
It is used for trimming the remaining material of the bush after cold pressing.
It's designed to trim 2pcs/time (14~18pcs/min)
4. Grooving Machine
It is used for making the groove, so that the PP material can combine the bush tightly, moreover, it will increase acid climbing distance and accordingly reduce acid climbing risk.
It's designed to groove 2pcs/time (14~18pcs/min)
Description
The cold pressing process flow is 4-step operation. They can work alone, not affected by the efficiency link of the other machine. The automatic lead parts casting machine is fully automatic, do not need a person to watch the operation; the cold pressing machine, trimming machine and grooving machine needs operator for each machine. Operator quantity might be increased to match the production due to different products and different operation efficiency. The rolling process is required if the user needs the inverted groove structure.
Operation
The automatic lead parts casting machine will make the rough lead parts; the operator will put the rough lead parts into the cold pressing mold inside the cold pressing machine, run the machine for single pressing; then use the trimming machine to trim the cold pressing small parts. Finally, use the grooving machine to make the groove for the lead parts.
