Description

A fully automatic ultrasonic water nozzle cutting machine

Technical Field

The utility model relates to the technical field of water nozzle cutting machines, in particular to a full-automatic ultrasonic water nozzle cutting machine.

Background technique

In the field of power ultrasound, the piezoelectric effect method is often used in plastic welding to generate acoustic energy. Ultrasonic waves convert high-frequency electrical energy into mechanical vibrations through transducers. The ultrasonic energy is then transmitted to the welding area through the upper weldment. Since the acoustic resistance of the welding area, i.e., the interface between the two welds, is large, local high temperature will be generated. Due to the poor thermal conductivity of plastics, it cannot be dissipated in time and gathers in the welding area, causing the contact surface of the two plastics to melt rapidly. After a certain pressure is applied, the two welded objects are fused into one. When ultrasonic waves act on a single plastic product, due to the local high temperature and a certain pressure is applied at the same time. The high temperature and high pressure at this point in the plastic are very easy to break, and this situation is often used in plastic nozzle removal operations. The parts that realize plastic welding and cutting are collectively referred to as welding units. It is usually composed of transducers, welding tools (molds), protective covers, leads, and air-cooling structures.

Due to the structural heterogeneity of plastic parts, the sprue removal methods for injection molded plastic products include manual removal, pneumatic scissor removal, laser cutting, ultrasonic cutting, etc. Manual removal is rarely used now because of its low efficiency and high labor intensity. Pneumatic removal often requires special scissors and has a large tooling space and high space requirements. Laser cutting is not widely used due to the presence of exhaust gas emissions. Ultrasonic cutting plays a vital role in sprue removal due to its fast speed and high degree of automation. However, due to the existence of a variety of plastic structures, the traditional practice is either to manually remove the sprue material after the plastic part is removed from the mold, or to place it on a special pneumatic or laser cutting tooling to perform the operation. However, the efficiency of these two types of removal is not high.

In large-scale injection molding of multi-cavity molds, the equipment is usually large, the installation and debugging workload is large, the processing and installation are time-consuming, and the volume is large, the adaptability and consistency are poor, which is not conducive to improving production efficiency.
