Precautions for equipment and commissioning of relevant parts of Wuxi shot blasting machine

1. Shot blaster:

When leaving the factory, the shot-blasting device of the hook type shot-blasting machine has been installed on the chamber body. Before use, pay attention to the problems to be debugged. Check whether the fixed orientation of the blade, shot splitter, directional sleeve and guard plate is accurate and firm, and check whether the rotation direction is correct by power-on jog. Then adjust the orientation of the opening of the directional sleeve. From the theoretical point of view, the angle between the front edge of the directional opening and the front edge of the blade throw out orientation is about 900. After fixing the orientation of the directional sleeve, you can detect the orientation of the shot belt. The method is to place a steel plate or board at the outlet of the hook type shot blasting machine above the orientation of the hanging workpiece, start the shot blasting machine, put a few (2-5kg) shots into the shot feed tube, and then stop the machine, Check whether the impacted position on the steel plate is suitable for the demand. If the window of the adjustable sleeve is closed downward, otherwise, it is the same until it is suitable to stop, and record the orientation of the sleeve mouth as the basis for replacing the sleeve in the future.

2. Hoist and screw conveyor:

First, carry out the no-load test of the hook type shot blasting machine to check whether the operation direction of the lifting bucket and the spiral blade is correct, and then tighten the belt of the lifting machine to the proper tightness to prevent deviation, and then carry out the load test to check the operation condition and transportation capacity of the hook type shot blasting machine, whether there is strange noise and vibration, and check and remove obstacles.

3. Shot sand separator:

First, check whether the ram movement of the hook type shot blasting machine is flexible, and then check whether the orientation of the split plate is moderate. Then, when the lifting machine is debugged under load, there is continuous steel shot inflow, and check whether the steel shot flows out and falls down in the form of a flow curtain during the blanking slot.

What aspects affect the great effect of shot blasting

1. Hardness of steel shot and sand. When the hardness of steel shot and sand is higher than that of parts, the change of its hardness value will not affect the shot blasting strength. If the workpiece is too soft at this time, be careful to be damaged, properly adjust the power of the shot blasting machine to reduce the shot blasting strength; When the steel shot and sand are softer than the parts, if the shot blasting hardness value decreases, the shot blasting strength also decreases. If the desired effect is not achieved, the power of the shot blasting machine can be appropriately increased to add the shot blasting strength.

2. Shot blasting rate. When the shot blasting rate is added, the shot blasting strength is also added, but when the rate is too high, the damage amount of steel shot and sand is added.

3. Thickness of steel shot and sand: the larger the steel shot and sand, the greater the impact kinetic energy, and the greater the shot blasting strength. Therefore, in order to ensure the strength of shot blasting, we should only choose the smaller steel shot and sand, so that the cleaning power will be relatively increased. The size of shot blasting is also bound by the shape of the part. When there is a groove on the part, the diameter of steel shot and sand shall be less than half of the inner radius of the groove.

4. Projection viewpoint. When the steel shot and steel sand jet are straight with the workpiece to be sprayed, the steel shot and steel sand have high strength and should be kept in this shape for shot blasting treatment. If it is bound by the shape of the part, the size and rate of steel shot and sand shall be appropriately increased when shot blasting with small view point is required.
