Advantages of the non-vibration shell shot blasting machine
Advantages of the shell removal and shot blasting machine (non-vibration shell shot blasting machine)
Traditional process: After pouring → Vibration of the shell removal machine to break the shell → Transportation → Ordinary shot blasting machine for cleaning;
The shell removal and shot blasting machine for castings directly takes on the complete ceramic shell with the casting, and the shot blasting impacts to break the shell, completing the tasks of shell removal, sand removal, and oxide removal in one go. There is no vibration shell removal mechanism.
A. Quality advantages of the non-vibration shell shot blasting machine
1. Eliminate damage to the casting caused by vibration
The strong mechanical vibration of the non-vibration shell machine completely solves the cracks, chipping, deformation, and hidden cracks that occur when vibrating the shell for thin-walled parts, thin ribs, high-temperature alloys, and stainless steel castings, significantly reducing the scrap rate, especially for high-precision castings with strict requirements.
2. More thorough shell removal
Multi-angle steel shot impact, the removal effect of shell residues in the cavities, corners, and ribs of the casting is better than that of the vibration shell machine; the vibration shell machine is prone to local shell material adhesion, and the bad rate of shell residues in this machine is significantly reduced, reducing the subsequent manual knocking of the shell, acid treatment processes.
3. Good surface quality consistency
Shell removal is completed simultaneously with shot blasting strengthening, the surface roughness of the casting is uniform, the oxide and sand are removed together, and the conditions for subsequent grinding and machining are better.
B. Process flow and production efficiency advantages of the non-vibration shell shot blasting machine
1. Process combination, simplified process
Cancel the independent vibration shell workstation, the shell-carrying castings are directly placed on the machine, shell removal + cleaning are integrated, eliminating the vibration shell, secondary transportation of the workpiece, and secondary clamping, reducing the intermediate transportation and turnover time.
2. Shorten production cycle, increase capacity
The original two pieces of equipment and two times of loading and unloading are now completed in a single machine; reducing the waiting time for workpiece circulation, suitable for batch continuous production, and can be connected to the finishing line after precision casting.
3. Reduce auxiliary processes
Most working conditions can omit manual knocking of the shell, rough shot blasting, and reliance on acid washing, shortening the overall production cycle.
C. Advantages in terms of manpower, space, and operating costs
1. Save manpower
Eliminate the operator of the vibration shell position, reduce the personnel for workpiece transportation and secondary loading and unloading, and reduce labor intensity.
2. Save workshop floor space
No need to simultaneously place two sets of equipment, vibration shell machine + ordinary shot blasting machine; a single machine can complete the functions of two sets of equipment, saving factory space.
3. Energy saving
Eliminate the energy consumption of the vibration shell machine and its supporting air compressor; the magnetic-wind separation secondary separator efficiently separates the steel shot from the ceramic shell slag, the steel shot is recycled, the loss of steel shot is controllable, and the cost of consumables is reduced.
4. Reduce auxiliary material consumption
Reduce the consumption of knocking tools, cutting discs, acid solutions, etc., as auxiliary materials.
D. Environmental protection and working environment advantages
1. Fully enclosed operation, dust controllable
The traditional vibration shell workstation is open, causing a lot of dust; this machine is overall enclosed, the crushed shell powder all enters the pulse bag dust collector, the dust is collected centrally, the workshop environment is improved, meeting the requirements of environmental protection emissions.
2. Lower noise
There is no high-frequency and intense vibration noise from the vibration shell machine, the main noise of the entire machine comes from the shot blasting machine, the noise environment of the workshop is better than the combination of vibration shell + shot blasting.
3. Automatic separation and discharge of waste residue
The crushed shell residue is automatically separated and discharged, the shell residue does not scatter on the ground, reducing the workload of cleaning in the workshop.
E. Brief disadvantages of the non-vibration shell shot blasting machine (reference)
1. For castings with particularly thick and extremely high strength shells, the shot blasting treatment time will increase; a small amount of residual shell in deep and narrow blind holes still requires a small amount of post-processing;
2. The one-time purchase cost of this equipment is higher than that of ordinary shot blasting machines.
