Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to an automatic chamfering device for PVC-U pipes. Background Technology

[0002] PVC-U pipes (rigid polyvinyl chloride pipes) are commonly used in water supply, drainage, sewage, and ventilation systems. They are made of polyvinyl chloride (PVC) resin and belong to the thermoplastic pipe category. To remove sharp edges after pipe cutting, prevent damage during installation, and ensure a tighter connection, PVC-U pipes need to be chamfered. Currently, chamfering is mostly semi-automatic. This involves placing the pipe in a corresponding clamp and using a chamfering tool. After processing, the pipe is manually removed and replaced with a new one for processing. This manual removal and replacement process takes extra time. Therefore, production efficiency is low, especially when processing large quantities of pipes, which can easily lead to insufficient capacity. Furthermore, manual operation introduces errors in pipe placement and removal, resulting in inaccurate pipe positioning and affecting the quality of the chamfering. Utility Model Content

[0003] The purpose of this invention is to provide an automatic chamfering device for PVC-U pipes to solve the problems mentioned in the background art.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, 6, 7, and 8, this utility model provides a technical solution: an automatic chamfering device for PVC-U pipes, comprising: an equipment box 1, one end of which is inclinedly fixedly connected to a guide trough 2; a support 3 fixedly connected to the top of the equipment box 1, with two end extrusion plates 6 for positioning the pipe ends being raised and lowered in the middle of the support 3; a support side 14 with a limiting groove 15 in the middle, two of which are fixedly connected to the top of the equipment box 1, and a serrated plate 16 between the two support sides 14 for transporting the pipe into the limiting groove 15; a driving part at the bottom of the serrated plate 16 for driving the serrated plate 16 to rise, fall, and move laterally; and a cutting part located on both sides of the equipment box 1, the cutting part including a chamfering knife 10 for chamfering.

[0027] It should be noted that a controller is provided in this embodiment. The PVC-U pipe is placed inside the guide trough 2. Under the action of gravity, the PVC-U pipe moves downward. Under the action of the limiting block 22 at the top of the serrated plate 16, the PVC-U pipe is blocked at the top of the support side 14. The drive unit drives the serrated plate 16 to rise, move laterally, and fall back to its original position. The PVC-U pipe is lifted by the V-shaped groove at the top of the serrated plate 16, so that its height is higher than the limiting block 22, and then it moves laterally, thereby transporting the PVC-U pipe to the top of the limiting groove 15. Then the drive unit drives the serrated plate 16 to move downward to place the PVC-U pipe in the limiting groove 15. The end extrusion plate 6 moves downward to extrude the two ends of the PVC-U pipe, thereby positioning the PVC-U pipe towards the center. The upper and lower clamping mechanisms fix the PVC-U pipe. The rotating chamfering blade 10 moves from both ends towards the PVC-U pipe to chamfer the pipe ends.

[0028] In one embodiment, a second cylinder 5 is fixedly connected to the middle of the bracket 3, a support frame 17 is fixedly connected to the middle of the equipment box 1 and at the position corresponding to the second cylinder 5, a dual-axis cylinder 20 is fixedly connected to the top of the serrated plate 16, and a fixing block 13 is fixedly connected to both the output end of the dual-axis cylinder 20 and the output end of the second cylinder 5.

[0029] It should be noted that in this embodiment, when the PVC-U pipe is fed into the limiting groove 15, cylinder 5 and dual-axis cylinder 20 extend simultaneously, and the PVC-U pipe is squeezed and fixed from the top and bottom by the fixing block 13. This facilitates the chamfering cutter 10 to process the PVC-U pipe.

[0030] In one embodiment, cylinder 4 is fixedly connected to the top of both ends of the equipment box 1, and end pressing plate 6 is fixedly connected to the output end of cylinder 4. One side of the bottom of end pressing plate 6 is a sloping structure, and a metal rod that is slidably connected to the bracket 3 is fixedly connected to the top of end pressing plate 6.

[0031] It should be noted that in this embodiment, when the PVC-U pipe is placed inside the limiting groove 15 (when the serrated plate 16 is in contact with the corresponding limit switch downwards), the cylinder 4 drives the end extrusion plate 6 to move downwards, so that the bottom inclined surface of the end extrusion plate 6 contacts the end face of the PVC-U pipe. The pipe is positioned towards the center by the extrusion of the inclined surface of the end extrusion plate 6, so that the pipe is located in the middle position of the equipment box 1. With the extrusion and fixation of the cylinder 5 and the dual-axis cylinder 20, it is convenient for the chamfering blade 10 to be at the same distance from the end of the PVC-U pipe. When the chamfering blade 10 moves towards the PVC-U pipe, the cylinder 4 drives the end extrusion plate 6 to reset upwards and be misaligned with the chamfering blade 10.

[0032] In one embodiment, the drive unit includes a dual-axis cylinder 18 fixedly connected to the inside of the support frame 17. A lifting platform 19 is fixedly connected to the top of the dual-axis cylinder 18, and a serrated plate 16 is slidably connected to the top of the lifting platform 19. A limiting block 22 for limiting the pipe is fixedly connected to the top of the serrated plate 16 and the end near the guide chute 2. A third cylinder 21 is fixedly connected inside the support frame 17. One end of the third cylinder 21 is fixedly connected to the end of the serrated plate 16 through a T-shaped plate, and the piston rod of the third cylinder 21 is slidably connected to the T-shaped plate.

[0033] It should be noted that in this embodiment, the pipe rolls downwards within the inclined guide trough 2 under the influence of gravity, and is fixed at the top of the support side 14 by the blocking of the limiting block 22. Two limit switches are fixedly connected to the inner side of the support side 14. When the end of the sawtooth plate 16 corresponds to the limit switch, the controller drives the sawtooth plate 16 to move downwards and then move laterally to reset, while simultaneously controlling the movement of cylinder 5, the dual-axis cylinder 20, and the corresponding chamfering blade 10. A linear guide rail is fixedly connected to the bottom of the serrated plate 16, and a slider is slidably connected to the bottom of the linear guide rail. The slider is fixedly connected to the lifting platform 19. When feeding PVC-U pipe, the dual-axis cylinder 18 drives the serrated plate 16 to rise through the lifting platform 19. The groove of the serrated plate 16 will be stuck on the outside of the pipe and lift the pipe, so that the top of the height limit block 22 at its bottom is reached. The linear guide rail and the serrated plate 16 are moved laterally on the top of the lifting platform 19 by the cylinder 21. When the end of the cylinder 21 reaches the limit position, the dual-axis cylinder 18 drives the lifting platform 19 to move downward, so that the pipe falls into the limit groove 15 on the top of the support side 14. Dual-axis cylinder 18 drives the serrated plate 16 to separate from the pipe, and cylinder 21 drives the serrated plate 16 to move laterally, so that its corresponding position moves to the position corresponding to the limit block 22. At this time, the groove at the front end of the serrated plate 16 corresponds to the pipe, which facilitates lifting the processed pipe and transporting it to the inclined surface at the end of the support side 14, so that it rolls down. During the process of the lifting platform 19 driving the serrated plate 16 to rise and fall, the piston rod of cylinder 21 slides up and down in the middle of the lifting platform 19 and the T-shaped plate.

[0034] In one embodiment, the cutting section includes support platforms 7 fixed to both sides of the equipment housing 1. A reducer 8 is slidably connected to the top of the support platform 7. A servo electric cylinder 12 for driving the reducer 8 to slide is fixedly connected to the top of the support platform 7. A motor 9 is mounted on the top of the reducer 8. The motor 9 is connected to the reducer 8 via a belt assembly. A support column 11 is fixedly connected to the middle of the reducer 8. A chamfering blade 10 is rotatably connected to the outside of the support column 11. The output end of the reducer 8 is connected to the chamfering blade 10.

[0035] It should be noted that in this embodiment, the output end of the reducer 8 is a hollow structure. The output end of the reducer 8 is fixedly connected to the chamfering tool 10 through a flange. One end of the support column 11 passes through the middle of the hollow structure of the reducer 8 and is fixedly connected to the reducer 8. During operation, the motor 9 drives the reducer 8 through the belt and pulley. The reducer 8 drives the chamfering tool 10 to rotate outside the support column 11. The servo cylinder 12 drives the reducer 8 to move towards the end of the pipe. The support column 11 is inserted into the inside of the pipe to support the pipe. The chamfering tool 10 contacts the end of the pipe to perform chamfering.
