Cleaning of the chamber: clean the residual projectiles and oxide scales on the bottom grille every shift to prevent accumulation from affecting the operation of the chain.
Hook system inspection: check whether the hoist turntable is flexible and whether the hook bolts are loose (focus on checking the load-bearing pin shaft).
The separator screen is inspected daily. When the screen holes are blocked by more than one-fifth, they are cleaned with a steel brush. If more than three holes are damaged, they are replaced immediately.
When the thickness of iron chips adsorbed on the surface of the magnetic separation drum exceeds 3 mm, stop the machine and scrape them to prevent impurities from mixing into the projectiles.
The accumulation chain push rod is lubricated once per shift (high temperature resistant lithium grease), and the track roller is oiled weekly to prevent jamming.
Cycle Core tasks Operation standards
Weekly 1. Shot blaster blade wear detection Single-side wear exceeding 2 mm or cracks need to be replaced in groups
2. Dust removal system pressure difference monitoring Backflush filter cartridge when pressure difference exceeds 1500 Pa
Monthly 1. Adjustment of catenary tensioning device The droop is controlled in the range of 15-18 mm
2. Rotating mechanism gearbox oil level check When the oil level is below the center line of the window, add VG320 gear oil
Quarterly 1. Shot blasting belt angle calibration
2. Accumulation chain buffer performance test
Step 1: Check the rotation speed of the workpiece (standard 2-4 rpm), adjust the inverter if the speed is insufficient
Step 2: Check the flow valve of the shot blaster, if the opening is inconsistent, it needs to be calibrated synchronously
Cause: track deformation or insufficient push rod air pressure
Handling: Correct track straightness and adjust air pressure to 0.5 MPa
For thin-walled parts such as rocker arms, low-shot strength parameter packages are provided
Warehouses in the United States and Mexico always have 10 types of vulnerable parts such as stacking chain push rods and directional sleeves, which can be delivered within 72 hours for urgent needs
Optional workpiece counting module: Automatically prompt to check the hook bearing every 5,000 pieces
Life improvement: The guard plate of the shot blasting room is made of Mn13 wear-resistant steel, and the service life exceeds 30,000 hours
Energy-saving advantage: Variable frequency chain speed adjustment saves more electricity than traditional models
