Knowledge of metal springs – compression springs

The reed, due to its spiral geometry, is more difficult to strengthen with its reinforcement work than the reed on the flat surface. In addition, the reinforcement effect of the transletion of the reed must be strictly evaluated to fully understand the resistance of the reed against fatigue fracture.

The reed scored in a separate delivery chain system into the blast chamber, which is equipped with a set of parallel rollers, which are reinforced while the rollers roll non-stop, driving the reeds to rotate the edge. This way of rotating allows the high-speed pellet flow through the rings of the reed seine to hit the metal surface of the ring, where the reed stress is most concentrated.

For applications with high capacity requirements, an enhanced device that can spray two reeds at the same time can be selected. The latest results are based on the original shot-reinforced equipment, combined with multiple nozzles, for more targeted, fire-focused shot treatment for specific areas of the reed (stress concentration pleasing).

The reed reinforcement can be used by a continuous pass-through shot reinforcement device for one by one reinforcement treatment, allowing the reed geometric recesse to be exposed to high-speed pellet flow. Typical models are a toss for the top of the ejection reed, with a toss on the side and a left and right side of the spray reed.

This standard reed reinforcement equipment has a pass speed of 10 ft/min and, if higher production speed is required, the number of toss can be increased and the motor frequency is adjusted. Under operating conditions, the reedist is repeatedly affected by one-way bending stress and is therefore sometimes stress-reinforced. In the process of reinforcement, the simulation reed will be “stress-reinforced” in the later use process, so that it is subjected to the direction of the load with a “static stress” at the same time, to its shot reinforcement. After the reinforcement is complete, release the additional static stress. Experiments show that stress reinforcement can further extend the service life of the reed sedifes than conventional reinforcement.
