Description

Self-adaptive pneumatic buffer device Technical Field The invention relates to the technical field of shock absorption and buffering of material transportation in a production line, in particular to a self-adaptive pneumatic buffering device for buffering bar stocks. Background In the industrial field of rapid development nowadays, the buffering technology is already applied to various fields of industry, such as common industrial production, there is often a scene of material mutual transportation or transfer, and once the material is transported or transferred, the material moves, there is motion inertia, and in order to stop the original motion trail as soon as possible, the buffering technology needs to be applied to buffering products. In some industrial fields with higher production precision or safety, there is a greater need for cushioning products that do not rebound and do not collide with and damage to the moving materials, then the original cushioning products are no longer suitable for the existing high-demand markets, for example, pure spring-type cushioning devices cannot meet such technical requirements, and pure pressure regulating cylinders cannot adapt to the current development environment because of the risk of rebound, so it is a necessary trend for those skilled in the art to develop an adaptive pneumatic cushioning device that can cushion moving materials without damage and rebound risk. Disclosure of Invention The embodiment provides a can play the buffering of harmless and do not have the pneumatic buffer of self-adaptation of resilience risk to the motion material, through setting up conventional cylinder device and come the body as the bolster, the rethread sets up the pressure balance system that can realize accurate pressure regulation and realizes cylinder device's no resilience buffering, this technical scheme simple structure easily maintains and maintains, application scope is wide, practice thrift the cost and improved precision and efficiency. Specifically, on the one hand, a self-adaptation pneumatic buffer for do not have the striking buffering of resilience to the material w of motion in the production line, be equipped with buffer cylinder q, still be equipped with impact dish p at buffer cylinder q's piston rod's tip, the material w of motion can make buffer cylinder q produce the compression of resilience after striking impact dish p and realize the buffering to material w, still be equipped with pressure balance system y, pressure balance system y is equipped with first gas circuit q1 and second gas circuit q2, first gas circuit q1 and second gas circuit q2 pass through tee bend joint and air supply u interconnect, just first gas circuit q1 and second gas circuit q2 all link up with buffer cylinder q each other and distribute respectively in buffer cylinder q's piston's both sides, when impact dish p received material w striking, the piston rod can realize striking and retract under the cooperation regulation of first gas circuit q1 and second gas circuit q2 and not rebound.
