Embodiment Construction

[0029] as attached figure 1 And attached figure 2 A collar device shown is installed on a frame with a horizontally arranged work panel 1, and is used to put a welding ring 101 on a pipe fitting, in particular, to put a welding ring on a U-shaped pipe elbow 100 101. When in use, the U-shaped pipe elbow 100 is fixed on a worktable, and the straight section port of the U-shaped pipe elbow 100 faces the collar device.

[0030] combined with figure 1 to attach Figure 9 As shown, the collar device includes a lower ring plate 2 , a push ring cylinder 3 , a mandrel 4 and a push ring cylinder driving mechanism 5 .

[0031] The lower ring plate 2 is uprightly fixed on the working panel 1, the lower ring plate 2 is provided with a descending passage 21 for the passage of the upright welding ring 101, and the lower end of the descending passage 21 has a welding ring 101 for the upright welding ring 101 to pass through. The horizontal channel 22 that slides in the axial direction of...

Abstract

The invention relates to a welding ring feeding device. The welding ring feeding device comprises a lower ring plate, wherein the lower ring plate is provided with a descending channel through which an upright welding ring passes; the lower end of the descending channel is provided with a welding ring berth. The welding ring feeding device is characterized by also comprising ring retaining bolts and ring penetrating bolts which are inserted into the descending channel alternately along the axis direction of the upright welding ring, wherein the ring retaining bolts are arranged below the ring penetrating bolts. The welding ring feeding device has the advantages of being simple in structure and easy to operate.

Description

(1) Technical field [0001] The invention relates to a welding ring feeding device. (2) Background technology [0002] As a compact heat exchanger, the tube-fin heat exchanger is widely used in the refrigeration industry. The forming process of the heat exchanger mainly has the following three forming processes: tube bending forming (forming U-shaped tubes), mechanical expansion tube forming (realizing tube-fin connection), tube bundle bending forming (forming L-shaped or G-shaped heat exchangers) ). [0003] After expanding the tubes, each U-shaped tube needs to be welded together with a U-shaped tube elbow. Before welding, it is necessary to put a welding ring on the straight section of the U-shaped pipe elbow. In the Chinese patent "Ring Machine" (Patent No. 2010105928634), four devices, namely the upper ring device, the ring shifting device, the ring device and the pressing ring device, are disclosed, which basically realize the straight section of the U-shaped pipe el...
