Description

Technical Field

[0001] The present invention discloses a grinding debris removal structure for a grinder and an internal and external grinder for pipes, and relates to a debris removal structure installed on an internal and external grinder for pipes, belonging to the technical field of pipe processing equipment, and particularly to a debris removal structure capable of cleaning debris on the surface of pipes and improving work efficiency. Background Art

[0002] After mechanical processing, there may be a hardened layer on the surface of the pipe. This hardened layer is brittle and has residual stress. It is easy to crack during the early use of the pipe. It is also very easy to oxidize, rust or accumulate impurities during the storage of the pipe. Therefore, they often need to be polished before use. The surface of the pipe after polishing is smooth, which is conducive to subsequent processing operations, such as painting, plating, etc. These coatings or plating can provide additional protection and extend the service life of the pipe. Therefore, polishing is an important step in pipe pretreatment, which is not only related to the appearance and performance of the pipe, but also directly affects its performance and life in subsequent applications. The existing pipe polishing device can generally only polish the inner wall or outer wall of the pipe alone. When the entire pipe needs to be polished, it is necessary to use a special internal polishing device to polish the inner wall and then use an external polishing device to polish the outer wall. In this process, workers are required to move the pipe many times, which not only has a high processing cost but also increases the workload and reduces work efficiency.

[0003] Announcement No. CN106863033B discloses a pipe grinder, comprising a workbench, motor frames are installed on both sides of the bottom of the inner cavity of the workbench, a motor is installed on the top of the motor frame, one side of the motor is connected to an output shaft, one side of the output shaft is connected to an operating table, one side of the operating table is connected to an electric telescopic rod, one side of the electric telescopic rod is connected to a grinding sheet, a baffle is fixedly connected to the bottom of the operating table, a buffer spring is connected to the bottom of the baffle, a support plate is installed at the bottom of the buffer spring, a pneumatic rod is fixedly connected to the bottom of the support plate, a fixed block is installed at the bottom of the pneumatic rod, a sliding block is movably connected to the top of the inner cavity of the workbench, a fixed seat is installed at the bottom of the sliding block, a clamping ring is provided in the inner cavity of the fixed seat, screws are connected to both sides of the clamping ring, a nut is connected to one side of the screw, a clamping block is fixedly connected to the bottom of the clamping ring, and pins are movably connected to both sides of the clamping block. The grinder can only grind both sides of the outer wall of the pipe. Grinding the outer wall requires workers to rotate the pipe multiple times, which has extremely low work efficiency and is easy to accidentally injure workers.

[0004] Announcement No. CN216633696U discloses a pipe inner wall grinding machine, including a base, a positioning mechanism fixedly arranged on the base, and a grinding mechanism arranged on the base, the positioning mechanism includes a plurality of positioning chucks arranged at one end of the base and a positioning seat arranged on the base, the positioning chuck is used to position one end of the pipe to be polished, the positioning seat is provided with a plurality of positioning grooves, the positioning grooves are used to position the other end of the pipe to be polished, and the grinding mechanism is used to grind the inner wall of the positioned pipe. The grinder can only grind the inner wall of the pipe, and after grinding, it needs to be manually reset and then grind for the second time, which increases extra workload.

[0005] In order to improve the above problems, the applicant filed another Chinese invention patent application entitled "A Pipe Internal and External Grinding Machine", which is a grinding device that drives the pipe to move through a transmission wheel and simultaneously grinds the inner and outer walls of the pipe through a grinding brush. However, part of the debris generated by the above device during the pipe grinding process is adsorbed on the pipe surface, and is easily squeezed on the pipe surface when transmitted through the transmission shaft, resulting in secondary wear.

Sliding bars (5) are fixedly mounted on both sides of the support plate (6). The outer contour of the sliding bar (5) is the same as that of the sliding groove (4), and the sliding bar (5) is slidably connected and placed in the sliding groove (4). Preferably, the cavity (21) is arranged in an 8-shape, and the cavity (21) does not penetrate the support plate (6). The hole (22) is arranged through the support plate (6) and is aligned with the central axis of the upper circular ring of the cavity (21). The protective plate (19) is fixedly placed on the support plate (6) and is placed vertically to the support plate (6). The outer wall grinding motor (11) is placed on the support plate (6) and below the protective plate (19). One end of the main gear (23) is connected to the support plate (6) via a bearing, and the other end of the main gear (23) is connected to the motor shaft of the outer wall grinding motor (11) and a support bearing is disposed between the main gear (23) and the support plate (6).

The cross-sectional diameter of the middle section of the grinding head (12) is larger than the width of the two ends, which can be stuck in the interior of the pipe for positioning, ensuring that the grinding head (12) remains stable inside the pipe, thereby improving the grinding effect; The purpose of being able to drive the pipe to move by the conveying wheel (20) and simultaneously grinding the inner and outer walls of the pipe by the grinding brush is achieved.
