Description

Technical Field

[0001] This utility model relates to a metal product bending angle testing machine, and in particular to a metal product bending angle testing machine, belonging to the field of metal bending technology. Background Technology

[0002] Metal pipe bends are pipe fittings made by bending straight pipe blanks into a specific arc using specialized processes. They achieve flexible layouts by changing the direction of the pipeline and are widely used in energy transmission, mechanical hydraulics, and building structures. They play a core role in optimizing space, reducing interfaces, and improving the overall system integrity.

[0003] Metal bends typically do not work independently; they require precise connections to other pipes, components, or equipment interfaces. If the angle is inaccurate, the pipe may not be able to be installed at all, or it may need to be forcibly twisted, generating additional stress. In addition, to install a pipe with the wrong angle, the flange or threaded joint may be forced into an abnormal stress state, resulting in poor sealing and causing fluid or gas leaks.

[0004] Therefore, there is an urgent need to improve a metal product bending angle testing machine to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a metal product bending angle testing machine, which can detect the angle of the bent pipe to ensure the accuracy of the bending angle and facilitate subsequent installation and use.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a metal product bending angle testing machine, comprising a worktable, a fixed clamping block fixedly installed on the worktable, a movable clamping block slidably connected to the worktable, a fixed disk fixedly installed on the worktable, a rotating clamping block connected to the fixed disk via a connecting shaft, a clamping plate fixedly installed on one side of the rotating clamping block, and a protractor fixedly installed on the rotating clamping block.

[0007] Preferably, the fixed disk is slidably connected to the connecting shaft, and the connecting shaft is rotatably connected to the rotating clamp.

[0008] Preferably, the worktable is provided with a sliding groove, and a sliding block is slidably connected in the sliding groove. The sliding block is fixedly connected to one side of the movable clamping block.

[0009] Preferably, a first spring is fixedly installed between the sliding block and the worktable, the first spring is located inside the sliding groove, and a threaded rod is threadedly connected to the movable clamping block.

[0010] Preferably, the threaded rod is rotatably connected to the fixed clamping block, and a guide rod is interactively connected to the movable clamping block. The guide rod passes through the fixed clamping block, and both ends of the guide rod are fixedly connected to the worktable.

[0011] Preferably, a plurality of second springs are fixedly installed on one side of both the fixed clamping block and the movable clamping block, and a clamping plate is fixedly installed on the other end of the second spring.

[0012] Preferably, a rubber anti-slip layer is fixedly installed on the end of the clamping plate away from the second spring.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. The operator first slides the connecting shaft away from the fixed plate, places the bent pipe between the fixed clamp and the movable clamp, and simultaneously slides the movable clamp to ensure that the fixed and movable clamps can stably hold the straight section of the bent pipe. At this point, the operator slides the connecting shaft and the fixed plate together, ensuring the clamp plate contacts the fixed clamp, the pointer of the protractor is aligned with the edge of the fixed clamp, and the connecting shaft is positioned at the bend of the bent pipe. Figure 1 As shown, the worker rotates the clamping block, which in turn rotates the clamping plate, connecting shaft, and protractor together. The rotation is centered on the connecting shaft. The angle between the pointer of the protractor and the edge of the fixed clamping block can be used to determine the angle of the bent pipe, thus clarifying whether the angle of the bent pipe meets the standard.

[0015] 2. After the operator places the bent pipe between the fixed clamp and the movable clamp, rotate the threaded rod clockwise to move the movable clamp towards the fixed clamp until the clamping plates on both the fixed and movable clamps are in contact with the bent pipe. At this point, the operator continues to rotate the threaded rod to make the movable clamp slide slightly towards the fixed clamp, compressing the second spring. The movable and fixed clamps then firmly clamp the bent pipe. Meanwhile, a rubber anti-slip layer is fixedly installed on one side of the clamping plate to prevent the bent pipe from slipping and causing inaccurate measurement data. Attached Figure Description

Detailed Implementation

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Examples, such as Figures 1-4 As shown, a metal product pipe bending angle testing machine includes a worktable 1, a fixed clamping block 2 fixedly mounted on the worktable 1, a movable clamping block 3 slidably connected to the worktable 1, a fixed disk 101 fixedly mounted on the worktable 1, a rotating clamping block 6 connected to the fixed disk 101 via a connecting shaft 102, a clamping plate 4 fixedly mounted on one side of the rotating clamping block 6, a protractor 5 fixedly mounted on the rotating clamping block 6, the fixed disk 101 slidably connected to the connecting shaft 102, and the connecting shaft 102 rotatably connected to the rotating clamping block 6. First, the worker slides the connecting shaft 102 away from the fixed plate 101. Then, the bent pipe is placed between the fixed clamp 2 and the movable clamp 3. Simultaneously, the movable clamp 3 is slid to ensure that the fixed clamp 2 and the movable clamp 3 stably clamp the straight section of the bent pipe. At this point, the worker slides the connecting shaft 102 onto the fixed plate 101, with the clamping plate 4 contacting the fixed clamp 2. The pointer of the protractor 5 is aligned with the edge of the fixed clamp 2, and the connecting shaft 102 is positioned at the bend of the bent pipe. Figure 1 As shown, at this time, the worker rotates the clamping block 6, which in turn drives the clamping plate 4, the connecting shaft 102 and the protractor 5 to rotate together. The rotation is centered on the connecting shaft 102. The angle between the pointer of the protractor 5 and the edge of the fixed clamping block 2 can be used to determine whether the angle of the bent pipe meets the standard.

[0024] like Figures 2-3As shown, further, a sliding groove 8 is provided on the workbench 1, and a sliding block 10 is slidably connected in the sliding groove 8. The sliding block 10 is fixedly connected to one side of the movable clamping block 3. A first spring 9 is fixedly installed between the sliding block 10 and the workbench 1. The first spring 9 is located inside the sliding groove 8. A threaded rod 7 is threadedly connected to the movable clamping block 3. The threaded rod 7 is rotatably connected to the fixed clamping block 2. A guide rod 11 is interactively connected to the movable clamping block 3. The guide rod 11 passes through the fixed clamping block 2, and both ends of the guide rod 11 are fixedly connected to the workbench 1. By setting the threaded rod 7 to be threadedly connected to the movable clamping block 3, when the operator rotates the threaded rod 7, it causes... The movable clamping block 3 moves, and the sliding block 10, which is fixedly connected to the movable clamping block 3, is slidably connected to the sliding groove 8 opened on the worktable 1, so that the movable clamping block 3 moves more smoothly. The first spring 9 is fixedly installed between the sliding block 10 and the worktable 1. The first spring 9 is in a compressed state, that is, it always pushes the sliding block 10 forward. Therefore, the operator needs to use more force when reversing the threaded rod 7 to avoid the threaded rod 7 being rotated by slight contact, which would cause the movable clamping block 3 to move and thus cause instability in the clamping of the bent pipe. At the same time, the movable clamping block 3 is slidably connected to the guide rod 11, which makes the movement of the movable clamping block 3 more stable.

[0025] like Figure 3 As shown, furthermore, several second springs 12 are fixedly installed on one side of both the fixed clamping block 2 and the movable clamping block 3. A clamping plate 13 is fixedly installed on the other end of each second spring 12. A rubber anti-slip layer 14 is fixedly installed on the end of the clamping plate 13 away from the second spring 12. By setting several second springs 12 fixedly installed on one side of both the fixed clamping block 2 and the movable clamping block 3, and a clamping plate 13 fixedly installed on the other end of each second spring 12, when the worker places the bent pipe between the fixed clamping block 2 and the movable clamping block 3, it will move clockwise... The needle rotates the threaded rod 7, causing the movable clamping block 3 to move towards the fixed clamping block 2 until both the fixed clamping block 2 and the clamping plate 13 on the movable clamping block 3 are in contact with the bent pipe. At this time, the operator continues to rotate the threaded rod 7, causing the movable clamping block 3 to continue to slide slightly towards the fixed clamping block 2, causing the second spring 12 to be compressed. At this time, the movable clamping block 3 and the fixed clamping block 2 firmly clamp the bent pipe. Meanwhile, a rubber anti-slip layer 14 is fixedly installed on one side of the clamping plate 13 to prevent the bent pipe from slipping and causing inaccurate measurement data.

[0026] In this embodiment, as Figures 1-4 As shown in this embodiment, the principle of a metal product bending angle testing machine is as follows:

[0027] First, the operator slides the connecting shaft 102 away from the fixed plate 101. Then, the bent pipe is placed between the fixed clamp 2 and the movable clamp 3. The threaded rod 7 is rotated clockwise, causing the movable clamp 3 to move towards the fixed clamp 2 until both the fixed clamp 2 and the clamping plate 13 on the movable clamp 3 are in contact with the bent pipe. At this point, the operator continues to rotate the threaded rod 7, causing the movable clamp 3 to slide slightly towards the fixed clamp 2, compressing the second spring 12. The movable clamp 3 and the fixed clamp 2 then firmly clamp the bent pipe. The operator then slides the connecting shaft 102 onto the fixed plate 101, with the clamping plate 4 in contact with the fixed clamp 2. The pointer of the protractor 5 is aligned with the edge of the fixed clamp 2, and the connecting shaft 102 is positioned at the bend of the bent pipe. Figure 1 As shown, at this time, the worker rotates the clamping block 6, which in turn drives the clamping plate 4, the connecting shaft 102 and the protractor 5 to rotate together. The rotation is centered on the connecting shaft 102. The angle between the pointer of the protractor 5 and the edge of the fixed clamping block 2 can be used to determine whether the angle of the bent pipe meets the standard.
