Description

Technical Field

[0001] This utility model relates to the field of PE pipe processing, specifically to a grinding device for PE pipe processing. Background Technology

[0002] PE pipe is a type of plastic pipe made of polyethylene material through an extrusion molding process. Polyethylene is a linear polymer with good flexibility, corrosion resistance and wear resistance. It is widely used in many fields such as municipal water supply and drainage systems, gas transmission systems, and farmland irrigation systems. In the production and processing of PE pipe, the ends or surfaces of the pipe need to be ground to remove burrs, ensure the sealing of the connection and a good appearance.

[0003] Traditional edge grinding methods often involve manual operation using hand-held sandpaper or simple grinding tools, which suffers from low efficiency, uneven grinding, high labor intensity, and difficulty in guaranteeing processing quality. Existing edge grinding devices are complex in structure, inconvenient to operate, and cannot be flexibly adjusted according to different diameter PE pipes, resulting in poor applicability. Therefore, an edge grinding device for PE pipe processing is proposed to solve the above problems. Utility Model Content

[0026] 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.

[0027] In the embodiments, by Figure 1-4This invention discloses a grinding device for processing PE pipes. The device includes a base 1, with four first hydraulic push rods 2 fixedly connected to the top of the base 1, symmetrically distributed in pairs. The tops of the four first hydraulic push rods 2 are all fixedly connected to a mounting plate 3. Two support plates 4, distributed in pairs, are fixedly connected to the top of the mounting plate 3. Each support plate 4 has a placement groove inside, and a support frame 5 is fixedly connected to the top of each support plate 4. Each support frame 5 has a pressing device 6 inside. A second hydraulic push rod 7 is fixedly connected to the top of the base 1. A fixing plate 8, slidably connected to the base 1, is fixedly connected to the outer side of the second hydraulic push rod 7. A third hydraulic push rod 9 is fixedly connected to the outer side of the fixing plate 8. A mounting frame 10, slidably connected to the fixing plate 8, is fixedly connected to the outer side of the third hydraulic push rod 9. A grinding device 11 is fixedly connected inside the mounting frame 10.

[0028] The single clamping device 6 includes a threaded rod 61 that is internally threaded to a single support frame 5. A knob 62 is fixedly connected to the top of the threaded rod 61, and a pressure plate 63 is rotatably connected to the bottom of the threaded rod 61.

[0029] In this embodiment, during actual use, the knob 62 is provided to turn the threaded rod 61. At this time, the pressure plate 63 will move and press and fix the pipe during the pressing process to prevent the pipe from shaking during the grinding process.

[0030] Among them, the outer side of the pressure plate 63 is fixedly connected to the limiting rod 12 which is slidably connected to the support frame 5. The inside of the pressure plate 63 and the inside of the placement groove are both arc-shaped. The inside of the pressure plate 63 and the inside of the placement groove are both provided with buffer pads.

[0031] In this embodiment, during actual use, the limiting rod 12 can limit the downward direction of the pressure plate 63, so that the pressure plate 63 can always maintain a correspondence with the arc surface of the placement groove, so that it can fit the pipe more closely together with the placement groove. At the same time, the buffer pad is a rubber pad, which can enhance the friction between the pipe and the pressure plate 63 and the placement groove, making the pipe more stable.

[0032] Among them, the front and rear sides of the two support frames 5 are threaded with bolt knobs 13, and the outer sides of the two bolt knobs 13 are fixedly connected with limit plates 14.

[0033] In this embodiment, during actual use, when the bolt knob 13 is turned, the limiting plate 14 will also move so that the limiting plates 14 on both sides can limit and assist in fixing the pipeline. The outer side of the limiting plate 14 is also provided with a rubber pad to enhance friction and prevent damage to the pipeline.

[0034] The fixed plate 8 has a groove inside, and the mounting bracket 10 has a slider 15 that is slidably connected to the groove on the outside.

[0035] In this embodiment, during actual use, the third hydraulic push rod 9 can push or pull the mounting bracket 10 to move horizontally, so that the grinding equipment 11 can perform horizontal grinding, change its grinding position, and increase its grinding range, so as to fully grind pipes with larger diameters.

[0036] The base 1 has two sliding rods 16 fixedly connected inside and symmetrically distributed front and back, and the bottom of the fixed plate 8 has two sliding sleeves 17 fixedly connected to the two sliding rods 16 respectively.

[0037] In this embodiment, during actual use, the second hydraulic push rod 7 can push or pull the fixed plate 8 to move left and right. When the fixed plate 8 moves, the sliding sleeve 17 below it will slide on the outside of the sliding rod 16. The sliding sleeve 17 provides support for the fixed plate 8. The sliding rod 16 and the pushing direction of the second hydraulic push rod 7 are parallel, which restricts the movement direction of the fixed plate 8. In addition, a dustproof telescopic protective sleeve is provided on the outside of the sliding rod 16, which can effectively prevent foreign objects such as dust, oil, and moisture from entering between the sliding rod 16 and the sliding sleeve 17, thus protecting them.

[0038] Working principle:

[0039] When grinding PE pipes, the pipe is first inserted into the two support frames 5 from the side. Then, the pressure plate 63 is pressed down by the knob 62 to tighten and fix the pipe. Subsequently, the limit plate 14 can be moved by multiple bolts and knobs 13 to provide auxiliary support and fixation on both sides of the pipe. During grinding, the second hydraulic push rod 7 will push the grinding equipment 11 to approach and contact the edge of the pipe. The grinding equipment 11 consists of a motor and a grinding disc. The grinding disc will grind the edge. As the third hydraulic push rod 9 pushes or pulls the mounting frame 10, the pipe position within a certain height can be fully ground. At this time, the pipe can be raised and lowered in conjunction with the first hydraulic push rod 2 to change the grinding position of the pipe, so that the grinding equipment 11 can grind the pipe comprehensively. The motor and hydraulic push rod are used in conjunction with encoders, motor controllers, etc., or PLCs or professional motion controllers are used to write control programs to centrally control the motor or hydraulic push rod, monitor the rotation angle and speed of the motor in real time, and convert this information into electrical signals to feed back to the controller to achieve precise control of the motor and hydraulic push rod.
