Problems solved by technology

[0004] However, there are deficiencies in the above two structures, which are mainly reflected in the fact that the selection of the expansion rod requires the expansion rod to forcibly pass through the damping mechanism of the damping channel, which easily leads to the failure of the damping mechanism

Embodiment Construction

[0033] as attached figure 1 As shown, the selection device of the expansion rod includes a frame (not shown in the figure), a slide plate 2 and a suspension device.

[0034] The sliding plate 2 can be slidably installed on the frame, and the sliding plate 2 is provided with several sliding passages 21 for the expansion rod 6 to pass through. The sliding passage 21 is a stepped hole, and each sliding passage 21 is equipped with a lockable Or unclamp the lock bar mechanism of expansion bar 6. The locking bar mechanism includes at least one locking plate 4. When multiple locking plates 4 are provided to realize tube expansion, each expansion bar 6 can freely select the expansion tube length according to the actual situation. In this embodiment, there are two locking plates 4 .

[0035] The tail end of the expansion rod 6 is provided with a stopper 61 .

[0036] as attached figure 2 , attached image 3 , attached Figure 6 And attached Figure 7 Shown specifically, the loc...

Abstract

The invention relates to a suspending device for expanding arbors and a selecting device for the expanding arbors. The selecting device for the expanding arbors comprises a rack and a sliding plate which can be glidingly arranged on the rack; a plurality of sliding passages which can be used for the expanding arbors to pass are formed in the sliding plate; each sliding passage is configured with a locking rod mechanism capable of locking or loosening the expanding arbors; the selecting device for the expanding arbors also comprises the suspending device; a suspending plate is arranged on the rack; all suspending passages of the suspending deice are matched with all the sliding passages; and when each expanding arbor is loosened by the corresponding locking rod mechanism, the tail end of the expanding arbor can extend into the corresponding suspending passage and is suspended by locking on the suspending plate through the locking device. The suspending device and the selecting device disclosed by the invention have the advantages that the structure is stable, the expanding arbors can be selected without climbing to a high place, so that operation is safer, and work efficiency is high.

Description

technical field [0001] The invention relates to an expansion rod suspension device and an expansion rod selection device. Background technique [0002] The main function of the tube expander in the production process of the heat exchanger is to expand the diameter of the copper tube, so that the copper tube is in close contact with the cooling fins, avoiding looseness and increasing the thermal conductivity. Each tube expander is allowed to install hundreds of expansion rods, and the length of each expansion rod is generally 2-3 meters long. The number of copper tubes in the cooling fins of different heat exchangers is different. For the same tube expander When processing different heat exchangers, it is necessary to increase or decrease the expansion rods so that the number of expansion rods corresponds to the number of copper tubes. In the prior art, the operation of increasing or decreasing the expansion rods is generally done manually to increase the number of expansion...
