Multi-section hole-expanding integrated forming machine for reducer pipe for condensation of air conditioner

Abstract

The invention discloses a multi-section hole-expanding integrated forming machine for a reducer pipe for condensation of an air conditioner. The multi-section hole-expanding integrated forming machinecomprises a rack, a loading assembly, a positioning assembly and a hole-expanding assembly, the positioning assembly comprises a positioning groove, a feeding rod and a pipe clamping mold, the pipe clamping mold comprises a fixed bottom mold and a lifting top mold, and a placement hole is formed in the covered position of the fixed bottom mold and the lifting top mold; the hole-expanding assemblycomprises a hole-expanding box and a plurality of hole-expanding drill bits slidably connected into the hole-expanding box; and the end, away from the feeding rod, of the placement hole directly faces the hole-expanding drill bits, the hole diameter of the placement hole is arranged in a multi-section reducing mode in the direction away from the hole-expanding drill bits, and different hole diameters of all sections of the placement hole are matched with the diameters of the different hole-expanding drill bits correspondingly. The different hole-expanding drill bits can be matched with the placement hole, so that multi-section hole-expanding work on the reducer pipe is completed at a time, the complexity of an operating process is reduced, the work efficiency is effectively improved, thestep of linking among a plurality of individual processes during original multi-section hole-expanding operation is reduced, and the machining accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of processing variable-diameter tubes for air-conditioning condensation, in particular to a multi-stage reaming integrated molding machine for variable-diameter tubes for air-conditioning condensation. Background technique [0002] The variable-diameter tubes for air-conditioning condensation are used to discharge the condensed water generated by the indoor units during the cooling process of the air-conditioning. Each indoor unit needs a certain number of thin air-conditioning condensation-use variable-diameter tubes, which are routed at a certain slope and then collected into the large condensate. In the main pipe, and finally concentrated discharge. therefore. The current reducing tubes for air-conditioning condensation are mostly made of copper. On the one hand, the heat conduction efficiency is high, on the other hand, the corrosion resistance is strong, and at the same time, the bending performance is...

AI Technical Summary

Problems solved by technology

The current reducing tubes for air-conditioning condensation are mostly made of copper. On the one hand, the heat conduction efficiency is high, on the other hand, the corrosion resistance is strong, and at the same time, the bending performance is good and it is convenient for layout. It has a variety of different sizes and functions, and needs to be connected with each other, so the reducing pipe for air conditioning condensation at the reducing place needs to be processed at the end to adapt to the docking of different pipe diameters, and the tightness of the connection at the connecting point is relatively strict. High, in view of this, many manufacturers will expand or shrink the capillary port, here is a device for expanding the hole of the variable diameter tube used for air conditioning condensation
