Embodiment 1

[0024] Such as figure 1 and figure 2 As shown, the baffle plate structure of a pipe expander of the present invention includes a left chuck 1 and a right chuck 2 that are rotatably connected to the rotating shaft 3, and the corresponding left chuck 1 and right chuck 2 on the lower side of the rotating shaft 3 are closed. Finally, it forms a cuboid shape, and the matching surfaces of the two are jointly enclosed to form a circular jaw 4. The jaws 4 are symmetrically distributed on the left and right relative to the mating surface. The left chuck 1 and the right chuck corresponding to the upper side of the rotating shaft 3 The head 2 forms a left force application handle 5 and a right force application handle 6, and the left force application handle 5 and the right force application handle 6 are also symmetrically distributed on the left and right relative to the mating surface, on the corresponding rotating shaft 3 outside the inner port of the jaw 4 The coaxial rotation is c...

Embodiment 2

[0027] Such as Figure 5 As shown, the reset hanging plate 73 is integrally connected to the "one"-shaped member on the baffle plate 7, and the outer end of the reset hanging plate 73 extends to the outside of the surface of the right chuck 2 near the jaw 4 (two sides of the jaw 4). The left collet 1 and the right collet 2 corresponding to the side are mutually matched with the inner wall of the pipe expander on the pipe expander), the angle between the reset hanging plate 73 and the pipe fitting end face positioning plate 72 in this embodiment is less than 90°, and The outer end of the reset hanging plate 73 is arc-shaped (to reduce the friction force between it and the inner wall of the expansion chamber), and when the chuck after the clamping pipe fitting 8 is sent into the expansion chamber, the expansion chamber matched with it will The inner wall surface, that is, the overhead reset hanging plate 73 rotates clockwise downward around the rotating shaft 3, thereby driving ...

Embodiment 3

[0029] Such as Figure 6 and Figure 7 As shown, the reset hanging plate 73 is integrally connected to the "one"-shaped member on the baffle plate 7, and the outer end of the reset hanging plate 73 extends to the outside of the surface of the right chuck 2 near the jaw 4 (two sides of the jaw 4). The left collet 1 and the right collet 2 corresponding to the side are mutually matched with the inner wall of the pipe expander on the pipe expander), and the included angle between the reset hanging plate 73 and the positioning plate 72 on the end face of the pipe fitting is ≥90° (two in this embodiment or close to 90°), when the chuck with the pipe fitting 8 clamped is sent into the expansion chamber for chuck clamping, the outer end of the reset hanging plate 73 is hooked on the edge of the expansion chamber port, so that the end surface of the pipe fitting is positioned The plate 72 rotates counterclockwise around the rotating shaft 3 and leaves the port of the jaw 4 . All the ...

Abstract

The invention discloses a baffle plate structure of a pipe expander, provides a baffle plate structure of a pipe expander with a simple structure, the baffle plate can be automatically positioned before clamping, the clamping is convenient and fast, and the clamping efficiency is improved. It eliminates the technical problems that the baffle plate needs to be manually positioned when the chuck is clamped in the prior art, which is time-consuming and laborious, resulting in low clamping efficiency and other technical problems. It includes rotating the left chuck and the right chuck connected to the shaft, and one side of the shaft corresponds to A circular jaw is formed between the left chuck and the right chuck, the other side forms a left force application handle and a right force application handle, and a baffle plate is also rotated on the shaft, and one end of the baffle plate extends outward to form a Positioning splint, the other end of the baffle extends outward to form a positioning plate for the end face of the pipe fitting. When the jaws are opened, the outer end of the positioning splint is interfitted and clamped between the left force application handle and the right force application handle, and the end face positioning plate of the pipe fitting is connected to the The end face of the fitting in the jaw.

Description

technical field [0001] The invention relates to a baffle plate structure of a pipe expander, in particular to a baffle plate structure of a pipe expander with simple structure and automatic positioning of the baffle plate before clamping, thereby improving clamping efficiency. Background technique [0002] The pipe expander is a pipe expansion tool used to expand the inner and outer diameters of the pipes when manufacturing and maintaining various containers, so that the contact parts between the pipes and the tube sheet are tightly bonded, no air leakage and can withstand a certain pressure. It is widely used Used in the manufacture and maintenance of boilers, heat exchangers, condensers, coolers and other types of pressure vessels in petroleum, chemical, electric power, metallurgy, shipbuilding, refrigeration and other industries, such as the use of pipe expanders during the installation or maintenance of air conditioners Flare the refrigerant copper pipe. Existing pipe e...
