Description

Technical Field

[0001] This utility model relates to the field of hollow wall pipe technology, specifically a chamfering device for PVC axial hollow wall pipe. Background Technology

[0002] PVC axially hollow wall pipe is a type of plastic pipe with an axially hollow structure, made primarily of polyvinyl chloride (PVC) through a special process. It is widely used in municipal engineering, building water supply and drainage, and other fields.

[0003] In the processing and use of PVC hollow pipes, chamfering the pipe ends is an essential step. Newly cut pipe ends often have sharp burrs or right angles. Chamfering can smooth the edges, making subsequent pipe connection and installation operations smoother and effectively preventing personnel from being scratched or equipment from being damaged during transportation and installation. However, the current common chamfering method is still mainly manual. Although some automated chamfering devices have been put into use, most of these devices have functional limitations. They can usually only chamfer the inner or outer wall of the pipe, and cannot process the inner and outer walls simultaneously. This limits the processing efficiency and applicability to a certain extent. At the same time, the chamfering angle of current chamfering devices is generally fixed, which is not convenient to adjust according to different pipe chamfering requirements. Utility Model Content

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Please see Figure 1-5 As shown, a chamfering device for PVC axial hollow wall pipes includes a base plate 1, and further includes:

[0024] Support frames 2 are fixed on both sides of the top of the base plate 1. Support plates 3 are fixedly connected between opposite sides of the two support frames 2. Positioning frames 4 are fixedly connected between the tops of the two support plates 3. Hydraulic rods 5 are fixedly connected to the top of the inner cavity of the positioning frame 4. Pipes 9 are provided between the tops of the two support frames 2.

[0025] A ring frame 6 is fixed to one side of the top of the base plate 1. An L-shaped frame 7 is provided on one side of the ring frame 6. A drive component 8 for chamfering the pipe 9 is fixedly connected to one side of the L-shaped frame 7. The drive component 8 includes a motor 801, which is fixed to one side of the L-shaped frame 7. The output end of the motor 801 passes through to one side of the L-shaped frame 7 and is fixedly connected to a transmission rod 802. A guide plate 803 is fixedly connected to one side of the transmission rod 802. The support frame 2 facilitates the support of the pipe 9. The support plate 3, together with the positioning frame 4, facilitates the fixed installation of the hydraulic rod 5. The hydraulic rod 5 facilitates the subsequent limiting and fixing of the pipe 9. The ring frame 6 can assist in limiting the L-shaped frame 7. The chamfering of the pipe 9 can be achieved through the setting of the drive component 8.

[0026] A positioning plate 804 is fixedly connected to one side of the guide plate 803. A blade 805 is rotatably connected to one side of the positioning plate 804. Two extension plates 806 are fixedly connected to one side of the guide plate 803. A fixing plate 807 is fixedly connected to one side of the extension plates 806. A lead screw 808 is rotatably connected inside the fixing plate 807. A torsion block 809 is fixedly connected to one end of the lead screw 808. A retaining plate 810 is rotatably connected to the other side of the lead screw 808. One side of the retaining plate 810 is hinged to the blade 805. A sliding plate 811 is fixedly connected to one side of the guide plate 803. The annular frame 6 has an internal opening for... The sliding groove 812 used in the sliding plate 811 is connected to the blade 805 by a rotation limit through the positioning plate 804. If the user needs to adjust the amplitude of the blade 805, the torsion block 809 can be rotated. At this time, the lead screw 808 will rotate inside the fixed plate 807. Then, the lead screw 808 cooperates with the rotational connection of the fixed plate 810 to make the hinged blade 805 rotate and move around the positioning plate 804 as the central axis, thereby adjusting the thickness and amplitude of the chamfer. The sliding connection between the sliding plate 811 and the sliding groove 812 can improve the stability of the guide plate 803 during rotation.

[0027] The drive unit 8 also includes a threaded rod 813, which is rotatably connected to the inside of the L-shaped frame 7. The bottom of the L-shaped frame 7 is slidably connected to the inside of the ring frame 6. One end of the threaded rod 813 is rotatably connected to the ring frame 6 via a bearing. One end of the threaded rod 813 is fixedly connected to a turntable 814. When the user needs to move the L-shaped frame 7 to cooperate with the blade 805 to chamfer the pipe 9, the turntable 814 can be rotated. When the turntable 814 rotates, it will drive the threaded rod 813 to rotate. At this time, the threaded rod 813 will rotate on one side of the ring frame 6. At this time, the L-shaped frame 7 will move within the ring frame 6, thereby allowing the transmission rod 802 to gradually approach the pipe 9 with the guide plate 803 to perform the chamfering work.

[0028] The support frame 2 is V-shaped, and a first rubber pad 10 is fixedly connected inside the support frame 2. A connecting plate 11 is fixedly connected to the piston end of the hydraulic rod 5. Push rods 12 are fixedly connected to both sides of the bottom of the connecting plate 11. A retaining ring 13 is fixedly connected to the bottom of the push rod 12. A second rubber pad 14 is fixedly connected to one side of the retaining ring 13. The V-shape of the support frame 2, combined with the first rubber pad 10, can frictionally limit the pipe 9 and prevent the bottom from loosening during the chamfering process. The piston end of the hydraulic rod 5, together with the connecting plate 11, drives the push rod 12 to move. As the push rod 12 moves, it will drive the retaining ring 13 to descend, thereby limiting and fixing the top of the pipe 9, thus effectively preventing the pipe 9 from loosening during the chamfering process.

[0029] Working principle: First, the pipe 9 is placed inside the support frame 2. Then, the piston end of the hydraulic rod 5, in conjunction with the connecting plate 11, drives the push rod 12 to move. As the push rod 12 moves, it causes the retaining ring 13 to descend, thereby limiting and fixing the top of the pipe 9, effectively preventing the pipe 9 from loosening during the chamfering process. Before chamfering, if the user needs to adjust the chamfering angle, the torsion block 809 is rotated. At this time, the lead screw 808 will rotate inside the fixed plate 807. Subsequently, the lead screw 808, in conjunction with the rotational connection of the retaining plate 810, causes the hinged blade 805 to rotate and move around the positioning plate 804 as the central axis, which can adjust the angle of the two blades 805. Then, the motor 801 is turned on to transmit power. When the moving rod 802 rotates, the transmission rod 802 drives the guide plate 803 to rotate. When the guide plate 803 rotates, it also drives the sliding plate 811 to rotate inside the groove 812, thereby improving the stability of the guide plate 803 during rotation. When the user needs to move the L-shaped frame 7 to cooperate with the blade 805 to chamfer the pipe 9, the turntable 814 can be rotated. When the turntable 814 rotates, it drives the threaded rod 813 to rotate. At this time, the threaded rod 813 will rotate on one side of the ring frame 6, and the L-shaped frame 7 will move in a limited position inside the ring frame 6, so that the transmission rod 802, together with the guide plate 803, gradually approaches the pipe 9, and gradually achieves the chamfering work on the pipe 9 through the inlet of the two blades 805.
