Embodiment Construction

[0022] Examples such as Figures 1 to 7 As shown in the figure, an expansion rod-free structure is installed on the expansion rod machine, which facilitates the switch between the working and non-working of the expansion rod, and does not need to replace the expansion rod repeatedly, thereby reducing the workload and improving efficiency. The rod expander includes a frame 6, a power base 1 arranged on the frame 6, a discharge base 2 connected to the power base 1 through a boom 7, and the frame 6 is fixedly provided with a benchmark under the discharge base 2. Taiwan 8. A group of expansion rods 3 fixed on the power base 1 are also provided. The power seat 1 drives the unloading seat 2 to move up and down, and is limited by the reference table 8 to realize the expansion of the expansion rod to the heat exchanger.

Abstract

The invention discloses a structure with an expanding rod free of being extracted and a pipe expander. The structure with the expanding rod free of being extracted includes a power seat, a discharging seat and an expanding rod, wherein an expanding rod clamping component is fixedly arranged on the discharging seat, and the power seat is provided with an expanding rod adjustment and fixing component. The expanding rod clamping component includes a clamping ring fixing plate which is provided with a set of clamping ring mounting holes allowing multiple sets of radiator expanding rods to pass through, and the expanding rod penetrates through the clamping ring mounting hole. Each mounting hole is provided with two holding rings for holding the expanding rod and a damping ring pressing the two holding rings. The expanding rod adjustment and fixing component includes an adjustment plate arranged on the power seat, and the adjustment plate is provided with expanding rod receding holes. The expanding rod extraction-free structure controls the expanding rod on the pipe expander to work or not to work through cooperation of the adjustment plate and the holding rings, realizes fast adjustment of the expanding rod, meets the requirement of different heat exchanger expanding pipes and is less in workload, simple, convenient to use and applicable to the field of pipe expanders.

Description

technical field [0001] The invention relates to the field of tube expanders, in particular to a structure for preventing expansion rods from being pulled out and a tube expander adopting the structure. Background technique [0002] The tube expander is an important equipment in the processing of radiators. Its principle is: use an expander rod, and set an expander ball larger than the diameter of the copper tube on its end face. Under the action of external force, the expansion ball squeezes the copper tube, expands the copper tube, and makes it closely contact with the heat sink to avoid loosening. [0003] When the tube expander expands the tubes of different radiators, it is necessary to adjust the position of the expansion rods due to the different positions of the copper tubes of the radiators. Existing tube expanders need to dismantle the existing expansion rods and then install new expansion rods. The operation is inconvenient and the workload is heavy. Especially wh...
