Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bending device, especially to a bathroom metal pipe fitting bending device. BACKGROUND

[0002] Bathroom metal pipe fittings refer to metal fittings used in bathroom facilities, such as sinks, toilets, and shower systems. These fittings usually include faucets, valves, joints, and hoses, and their main function is to connect and regulate water flow to ensure the normal operation of the bathroom system.

[0003] The existing patent CN217412041U discloses a metal pipe fitting bending device, which includes a bottom plate, a side plate fixedly connected to the lower surface of the bottom plate, a fixed plate fixedly connected to the right surface of the side plate, a fourth telescopic rod fixedly connected to the lower surface of the fixed plate, a support plate fixedly connected to the lower surface of the fourth telescopic rod, a sleeve fixedly connected to the upper surface of the support plate, a conical table fixedly connected to the upper surface of the bottom plate, and a rotating rod rotatably connected to the inside of the conical table.

[0004] This patent aims to solve the problem of not being able to use simultaneous axial twisting and axial bending by designing a conical table, a rotating wheel, and a telescopic rod, which can control the bending radius by changing the diameter of the conical table, achieving the purpose of easy operation.

[0005] However, in actual use, there are still some problems, such as: in the existing bending device, when the pipe fitting is bent, the positioning assembly is usually fixed by a single contact point metal at the bending position. Since only one point is used for support and fixation, the metal piece will bear a large stress during the bending process, and the stress cannot be evenly distributed during the bending process, resulting in stress concentration at a certain point or area. This stress concentration not only affects the quality of the bent piece, but also may cause deformation, cracking, or even rupture of the metal piece during the bending process.

[0006] Therefore, the utility model provides a bathroom metal pipe fitting bending device. UTILITY MODEL CONTENT

[0035] Further, in order to ensure that the arc-shaped positioning block 35 remains stable during positioning and does not deviate, as shown in Figure 1 , Figure 3 and Figure 4 : In this scheme, the auxiliary positioning assembly 4 includes a positioning slide rod 41, the outer side of the positioning slide rod 41 is fixedly connected to the rotating frame 31, the outer side of the positioning slide rod 41 is fixedly connected with a moving block 42, the inside of the moving block 42 is threadedly connected with a threaded rod 43, one end of the threaded rod 43 is fixedly connected with a rotating handle 44, the outer side of the rotating handle 44 is movably connected to the outer side of the rotating frame 31, the other end of the threaded rod 43 is fixedly connected with a limiting block 45, the outer side of the limiting block 45 is slidingly connected inside the moving block 42, the positioning slide rod 41 serves as a positioning reference, providing a basis for accurate operation of the entire auxiliary positioning system, the design of the moving block 42 enables it to slide smoothly along the positioning slide rod 41, thereby adjusting the specific position of the positioning assembly as required, the threaded rod 43 controls the position of the moving block 42 through rotation, thereby achieving fine adjustment of positioning, the design of the rotating handle 44 enables the operator to easily rotate the threaded rod 43, and the position of the moving block 42 can be accurately adjusted through simple manual operation, thereby adjusting the working state of the positioning slide rod 41, and the limiting block 45 ensures that the rotation of the threaded rod 43 can be effectively transmitted to the moving block 42 through this connection, controlling the sliding range thereof, until the arc-shaped positioning block 35 is fixedly connected therewith, preventing displacement of the arc-shaped positioning block 35.

[0038] In use: First, the bathroom metal pipe fittings are placed in the turntable 23 inside the bending assembly 2, the processing piece 24 closely adheres to the surface of the pipe, the screw rod 32 adjusts its position by rotating, and then drives the sliding block 33 to slide smoothly inside the rotating frame 31.

In order to ensure the stability of the arc-shaped positioning block 35 during positioning, the auxiliary positioning assembly 4 plays a key role.

Subsequently, by rotating the positioning shaft 21, the bending tool 22 is driven to perform circular motion around the pipe, which directly acts on the pipe, causing it to begin bending according to the predetermined trajectory. Then the rotation of the turntable 23 and the close cooperation of the processing piece 24 ensure the stability of the pipe during bending.
