Picks, as consumables with large consumption during mining construction, have a direct impact on service life and mining efficiency. After analyzing the cutting mechanism, comprehensive stress and failure modes, it was found that the failure modes of the picks are mostly the early loss of the alloy head caused by the serious wear of the tooth head.

IGJR-3型截齿等离子堆焊机 ■ IGJR-3 picket plasma surfacing machine
Picks, as consumables with large consumption during mining construction, have a direct impact on service life and mining efficiency. After analyzing the cutting mechanism, comprehensive stress and failure modes, it was found that the failure modes of the picks are mostly the early loss of the alloy head caused by the serious wear of the tooth head. Plasma pick cladding technology uses a numerical control platform, equipped with a micro-arc plasma power supply and a plasma torch, supporting "high-precision powder feeder" and "gasification and other size alloy ceramic powder". Through strict programming control, different pick picks Abrasion-resistant cladding is used to effectively ensure the wear resistance of the cladding layer, the bonding force with the substrate and the molding effect. The new cladding wear-resistant picks produced by this technology can effectively prevent the alloy head from falling off prematurely.
The IGJR-2C CNC plasma cutting cladding equipment has been improved several times, and the operation convenience and cladding quality stability have been greatly improved. The improvement of the workpiece clamping part makes it easier to load and unload the workpiece; the cladding trajectory algorithm is optimized to make the appearance of the cladding layer smoother and more uniform.
The main purpose
1. Wear-resistant cladding on various types of pick picks.
2. Surfacing welding and wear-resistant cladding for short shaft parts.
1. The lateral movement and pick-cutting rotation are servo driven and controlled by the whole machine numerical control system, so the workpiece can be loaded and unloaded quickly and accurately.
2. The plasma torch adopts the third-generation special-purpose internal-feed powder plasma torch with stable cladding quality. Equipped with a chiller to ensure the life of the plasma torch.
3. The vertical height and front-back position of the plasma torch are adjustable, and the deflection angle of the pick is adjustable, which is convenient for adjusting parameters of different picks.
4. The special plasma cladding powder feeder is adopted, and the powder is uniformly and stably, which effectively guarantees the quality of the cladding.
