Description of plastic pipe expanding machine Technical brief description of air-conditioning copper tube automatic expanding machine Patent of this invention This air-conditioning copper tube automatic expanding machine includes a sound card frame, a silo fixed on the sound card frame, a chain conveyor pipe connected to the silo inlet, and a hydraulic cylinder installed on the sound card frame. The characteristics are: including a support frame built on the sound card frame, a structure built on the support frame that can move back and forth, and a push rod built on the structure. The hydraulic cylinder of the hydraulic cylinder pushes the structure to move, and a cone with a slope is arranged above and below the structure; including a feeding seat fixed on the sound card frame, a feeding belt groove is arranged above and below the feeding seat, and the inlet and outlet of the chain conveyor pipe are connected to the The feed belt slot corresponds to the feed belt slot, and one side of the push rod can be located in the feed belt slot; it includes a stamping die for expansion fixed on the sound card rack, and the die hole of the stamping die corresponds to the feed belt slot; it includes a lifting system built between the feed seat and the stamping die and promoted by the cone slope and adjustable, and alignment holes are arranged on the upper and lower parts of the lifting system. When the air-conditioning copper pipe to be processed enters the die hole from the feed trough, the alignment hole is connected with the feed belt slot and the die hole; it includes a stamping die rod for stamping the air-conditioning copper pipe in the stamping die hole, and the hydraulic cylinder of the hydraulic cylinder pushes the stamping die rod; it includes a drop bin fixed under the sound card rack and located under the die hole.
It can continuously stamp the air-conditioning copper pipe, with high production efficiency, safe and reliable use.
