Description

technical field [0001] The invention relates to multi-axis intelligent robot suspended abrasive water jet 3D cutting equipment, in particular to suspended abrasive water jet cutting equipment. Background technique [0002] Existing abrasive water jet cutting devices are generally of the post-mixing type, that is, after high-pressure water passes through the water nozzle to form a high-speed jet, the abrasive is sucked in by the Venturi vacuum entrainment effect and then mixed with the water jet. The disadvantage of this method is that the abrasive is not easy to mix evenly with water, and it is difficult for the abrasive to accelerate in a short time to enter the center of the jet. In addition, the jet pressure required for metal cutting is relatively high, generally above 300MPa. Therefore, the high-pressure water generating device and the tightness requirements of each component and device in the system are relatively high, which will lead to short service life of the jet...

AI Technical Summary

Problems solved by technology

The technology of 5-axis waterjet is relatively mature in foreign countries, and the products are relatively stable, but the price is relatively expensive. However, there is still no mature 5-axis waterjet in China. Its advantages lie in that it can cut parts with taper and swing angle; the disadvantages are: The cutting swing angle is small, and when cutting some complex parts, the angle is not enough or there is a dead angle, and the cutting point cannot be reached

The characteristic of this type of equipment is that the high-pressure hard tube is used to wind the robot arm to deliver high-pressure water to the cutting nozzle. The high-pressure hard tube will affect the flexibility of the robot, and it is difficult for the post-mixing technology abrasive to reach the nozzle. Therefore, this type of equipment is pure water cutting. Can process soft materials
