Embodiment 1

[0036] Such as figure 2 shown.

[0037] An automatic pipe threading method for an air-conditioning heat exchanger that does not require a pipe replenishment process, comprising the following steps:

[0038] First, transfer the stack of fins together with the pallet from the stamping station of the punch press to the pipe threading table;

[0039] Secondly, insert a positioning pin for each row of fins, the upper end of each positioning pin is connected with the connecting plate, all positioning pins are inserted together, and a pin or a pin with a hole is installed at both ends of the connecting plate at the same time;

[0040]Third, when the stack of fins moves to the first pipe-passing station, the lifting mechanisms set on both sides of the production line rise to insert the pin holes or pins installed on the anti-lifting mechanism into the pins or belts on both sides of the positioning pin connecting plate. In the hole pin rod, the longitudinal positioning of the fin st...

Embodiment 2

[0045] Such as Figure 1-10 shown.

[0046] An automatic pipe-piercing production line for air-conditioning heat exchangers that does not require pipe replenishment. Its three-dimensional structure is as follows: figure 1 As shown, it includes a pipe threading workbench 1. The pipe threading workbench 1 is installed on the guide rail 2 and can move according to the production rhythm under the traction of the traction mechanism. A pallet return mechanism is installed at the end of the guide rail, and the pallet return mechanism is installed on the guide rail. The lower part, in order to transport the tray from the end of the guide rail to the beginning of the guide rail, and receive the fin stack 3 on the punch press 19 after rising; the guide rail 2 is sequentially installed with a positioning pin insertion device 4, a first pipe threading device 5, a positioning Needle pulling device 6, second tube threading device 7 and tray return mechanism 8, such as figure 2 , 3 As sh...

Abstract

An air conditioner heat exchanger automatic pipe penetrating method and production line without a pipe supplementing procedure are characterized in that two pipe penetrating machines of the same structures are used for completing stacking pipe penetrating with positioning pins and perforating without the positioning pins respectively, and when pipe penetrating is conducted without positioning, transverse positioning is achieved through a copper pipe pressing plate. According to the air conditioner heat exchanger automatic pipe penetrating method and production line, the full-automatic pipe penetrating problem of air conditioner radiator fins is fundamentally solved, and the length of the production line is fundamentally shortened.

Description

technical field [0001] The invention relates to an air conditioner preparation technology, in particular to an air conditioner heat exchanger finned copper pipe threading technology, in particular to an air conditioner heat exchanger automatic pipe threading method and production line without a pipe repair process. Background technique [0002] Traditional air-conditioning finned copper tubes are threaded manually. In order to improve production efficiency, reduce labor load, and improve pipe threading quality, people have been working on automatic pipe threading technology for a long time. Chinese patent ZL2012102330242 discloses a fully automatic Pipe threading equipment, which created the first automatic pipe threading technology with independent intellectual property rights in China. After that, through continuous improvement, the pipe threading technology has continued to mature. Chinese patent "2019106435211, a highly integrated automatic production equipment for air-co...
