Description

Technical Field

[0001] This utility model belongs to the field of copper pipe bending detection technology, and in particular relates to a bending detection device. Background Technology

[0002] During the production of ducted air conditioners, copper pipes need to be bent. To ensure smooth installation, the bending degree of the copper pipes needs to be checked.

[0003] Existing bending detection devices require manual inspection of the bending of copper pipes, which is cumbersome and time-consuming. Therefore, we propose a bending detection device. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a bending detection device that enables rapid detection of the bending of copper pipes.

[0005] In view of this, the present invention provides a curvature detection device, including a base, a detection mold fixedly connected to the top of the base, a placement groove formed on the outer wall of the detection mold, a bracket fixedly connected to the top edge of the base, a lifting cylinder fixedly connected to the inner wall of the bracket, a lifting seat fixedly connected to the output end of the lifting cylinder, a straightening mold fixedly connected to the outer wall of the lifting seat, a limiting rod fixedly connected to the outer wall of the bracket passing through the inner wall of the straightening mold, a pressure head fixedly connected to the top of the straightening mold, a straightening plate fixedly connected to the bottom of the straightening mold, a pressure sensor fixedly connected to the outer wall of the straightening mold, and a pressure rod provided below the straightening plate at the output end of the pressure sensor.

[0006] Based on the above structure, the staff places the copper tube in the placement groove inside the testing mold and observes whether the copper tube is completely in contact with the placement groove. If the copper tube is in contact with the placement groove, it means that the bending of the copper tube is qualified. If the copper tube cannot be in contact with the placement groove, it means that the bending of the copper tube is unqualified and the copper tube needs to be corrected.

[0007] Preferably, the testing mold and the straightening mold have the same shape as the copper tube. In this embodiment, the operator places the copper tube in the placement groove inside the testing mold and observes whether the copper tube is completely in contact with the placement groove to test the curvature of the copper tube.

[0008] Preferably, the straightening mold forms a lifting structure between the lifting cylinder, the lifting seat, and the limiting rod. The detection mold and the straightening mold are parallel. In this embodiment, the operation of the lifting cylinder drives the straightening mold on the outer wall of the lifting seat to slide vertically along the outer wall of the limiting rod, thereby achieving stable sliding operation of the straightening mold.

[0009] Preferably, the cross-sections of the straightening plate and the placement groove are both semi-circular. In this embodiment, this facilitates the sliding of the straightening mold to drive the pressure head and the straightening plate to fit against the outer wall of the copper tube.

[0010] Preferably, two sets of pressure heads are provided, and the two sets of pressure heads are located at both ends of the straightening mold. In this embodiment, by providing two sets of pressure heads, the copper tube is prevented from shifting during straightening.

[0011] Preferably, the pressure sensors are equidistantly distributed along the outer wall of the straightening mold. In this embodiment, this facilitates pressure detection operations at different parts of the copper tube.

[0012] Preferably, the pressure bar is perpendicular to the central axis of the straightening plate. In this embodiment, it is convenient to detect the pressure of the pressure bar on the outer wall of the copper tube by a pressure sensor. When the value of the pressure sensor remains unchanged, it indicates that the copper tube straightening is complete.

[0013] The beneficial effects of this utility model are:

[0014] 1. This bending detection device uses a placement groove. Workers place the copper tube into the placement groove inside the detection mold and observe whether the copper tube is completely in contact with the placement groove. If the copper tube is in contact with the placement groove, it means that the bending of the copper tube is qualified. If the copper tube cannot be in contact with the placement groove, it means that the bending of the copper tube is unqualified and the copper tube needs to be corrected.

[0015] 2. This curvature detection device, by setting up a pressure head and a straightening plate, uses a lifting cylinder to drive the straightening mold on the outer wall of the lifting seat to slide vertically along the outer wall of the limiting rod. The sliding of the straightening mold causes the pressure head and straightening plate to fit against the outer wall of the copper tube, thereby correcting the curvature of the copper tube. At the same time, a pressure sensor detects the pressure on the pressure rod on the outer wall of the copper tube. When the value of the pressure sensor remains unchanged, it indicates that the copper tube correction is complete. Attached Figure Description

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0024] This application discloses a curvature detection device, including a base 1, a detection mold 2 fixedly connected to the top of the base 1, a placement groove 3 opened on the outer wall of the detection mold 2, a bracket 4 fixedly connected to the top edge of the base 1, a lifting cylinder 5 fixedly connected to the inner wall of the bracket 4, a lifting seat 6 fixedly connected to the output end of the lifting cylinder 5, a straightening mold 7 fixedly connected to the outer wall of the lifting seat 6, a limiting rod 701 fixedly connected to the outer wall of the bracket 4 penetrating the inner wall of the straightening mold 7, a pressure head 8 fixedly connected to the top of the straightening mold 7, a straightening plate 9 fixedly connected to the bottom end of the straightening mold 7, a pressure sensor 10 fixedly connected to the outer wall of the straightening mold 7, and a pressure rod 11 provided below the output end of the pressure sensor 10 extending to the straightening plate 9.

[0025] Based on the above structure, the staff places the copper tube in the placement groove 3 inside the testing mold 2 and observes whether the copper tube is completely in contact with the placement groove 3. If the copper tube is in contact with the placement groove 3, it means that the bending of the copper tube is qualified. If the copper tube cannot be in contact with the placement groove 3, it means that the bending of the copper tube is unqualified and the copper tube needs to be corrected.

[0026] In one embodiment, the detection mold 2 and the correction mold 7 have the same shape as the copper tube.

[0027] In this embodiment, the operator places the copper tube in the placement groove 3 inside the testing mold 2 and observes whether the copper tube is completely in contact with the placement groove 3 to test the bending degree of the copper tube.

[0028] In one embodiment, the straightening mold 7 forms a lifting structure with the lifting cylinder 5 and the lifting seat 6 and the limiting rod 701, and the detection mold 2 and the straightening mold 7 are parallel.

[0029] In this embodiment, the lifting cylinder 5 drives the straightening mold 7 on the outer wall of the lifting seat 6 to slide vertically along the outer wall of the limiting rod 701, thereby achieving stable sliding operation of the straightening mold 7.

[0030] In one embodiment, both the straightening plate 9 and the placement groove 3 have semi-circular cross-sections.

[0031] In this embodiment, the straightening mold 7 is slidably driven to make the pressure head 8 and the straightening plate 9 fit against the outer wall of the copper tube.

[0032] In one embodiment, two sets of pressure heads 8 are provided, with the two sets of pressure heads 8 located at both ends of the straightening mold 7.

[0033] In this embodiment, by setting two sets of pressure heads 8, the copper tube is prevented from shifting during the correction process.

[0034] In one embodiment, pressure sensors 10 are equidistantly distributed along the outer wall of the straightening mold 7.

[0035] In this embodiment, it is convenient to perform pressure testing on different parts of the copper tube.

[0036] In one embodiment, the pressure bar 11 is perpendicular to the central axis of the straightening plate 9.

[0037] In this embodiment, the pressure of the pressure bar 11 on the outer wall of the copper tube can be detected by the pressure sensor 10. When the value of the pressure sensor 10 remains unchanged, it indicates that the copper tube correction is complete.

[0038] When using the bending detection device in this embodiment, the operator first places the copper tube in the placement groove 3 inside the detection mold 2 and observes whether the copper tube is completely in contact with the placement groove 3. If the copper tube is in contact with the placement groove 3, it means that the bending of the copper tube is qualified. If the copper tube cannot be in contact with the placement groove 3, it means that the bending of the copper tube is unqualified and the copper tube needs to be corrected.

[0039] Next, the lifting cylinder 5 operates to drive the straightening mold 7 on the outer wall of the lifting seat 6 to slide vertically along the outer wall of the limit rod 701. The sliding of the straightening mold 7 causes the pressure head 8 and the straightening plate 9 to fit against the outer wall of the copper tube, thereby straightening the curvature of the copper tube. At the same time, the pressure sensor 10 detects the pressure of the pressure rod 11 on the outer wall of the copper tube. When the value of the pressure sensor 10 remains unchanged, it indicates that the copper tube straightening is complete.
