Description

Technical Field

[0001] This invention relates to the field of steel pipe grinding technology, specifically a steel pipe outer diameter grinding machine. Background Technology

[0002] As customers demand higher quality steel pipes, the process of addressing oxide scale and defects on the outer surface of steel pipes becomes increasingly important. Traditional steel pipe grinding processes typically involve a drive roller that rotates the steel pipe, a guide wheel that moves the steel pipe horizontally, and a grinding wheel. These three components are generally in relatively fixed positions. During operation, the steel pipe to be ground needs to be manually inserted between these components, and then manually removed after grinding. This process results in low technical efficiency and a low degree of automation. Summary of the Invention

[0003] The purpose of this invention is to provide a steel pipe outer diameter grinding machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a steel pipe outer diameter grinding machine, comprising a working chamber, the interior of which is divided into a feeding chamber, a first storage chamber, and a second storage chamber by a partition. The feeding chamber is located between the first and second storage chambers, and a first guide plate is inclinedly arranged at the bottom end of the first storage chamber. A feed inlet communicating with the interior of the feeding chamber is provided through a side wall on one side of the first storage chamber. A drive roller and a support roller are rotatably mounted above the feeding chamber. A rotary drive component is provided at one end of the drive roller, and the support roller is driven by... The elastic support mechanism is horizontally movable on one side of the drive roller, and the elastic support mechanism is used to push the support roller to move closer to the drive roller. The top of the working chamber is fixed with a support frame, and the bottom of the support frame is movably mounted with a grinding mechanism via a linear drive mechanism on the side close to the first storage chamber. The linear drive mechanism is used to drive the grinding mechanism to slide back and forth horizontally along the axial direction of the drive roller. The feeding chamber is equipped with a feeding plate that is movably mounted up and down via a lifting component, which is used to vertically transport the steel pipe that rolls to the top of the feeding plate to the top of the drive roller and the support roller.

[0005] Furthermore, the polishing mechanism includes a bracket, a first polishing wheel and a second polishing wheel coaxially rotatably mounted on both sides inside the bracket, and a drive mechanism for driving the first polishing wheel and the second polishing wheel to rotate. A slider connected to the linear drive mechanism is mounted on the bracket.

[0006] Furthermore, a connecting plate is installed at the top of the bracket, and the connecting plate and the slider are connected by a linear drive, which is used to push the bracket and the slider to move up and down relative to each other.

[0007] Furthermore, the feeding plate includes a top plate horizontally disposed inside the feeding cavity and a baffle plate vertically fixed to the side of the top plate near the feed inlet. The bottom end of the feeding cavity is provided with a through hole to accommodate the baffle plate extending to the outside of the feeding cavity. The baffle plate is used to block the feed inlet.

[0008] Furthermore, both ends of the support roller are connected to movable blocks via rotating shafts, and the movable blocks are horizontally slidably connected to the working cavity. The elastic support mechanism includes a first fixed plate fixed on the working cavity and a first elastic support member disposed between the movable block and the first fixed plate. The first elastic support member is used to push the movable block to move horizontally toward the side closer to the drive roller.

[0009] Furthermore, each side of the working cavity near the movable block is provided with a positioning mechanism for locking the movable block. The positioning mechanism includes a second fixed plate fixed to the working cavity, a positioning rod slidably disposed on the second fixed plate, a limiting plate fixed to the top of the positioning rod, and a second elastic support member that pushes the positioning rod downward. The positioning rod is located above the movable block, and the top of the movable block is provided with a positioning hole that matches the positioning rod. Both ends of the feeding plate are provided with mounting plates, and the mounting plates extend to the bottom of the limiting plate. A top rod is vertically fixed to the top of the mounting plate, and the top rod is used to push the limiting plate upward when the feeding plate rises to feed material, so that the bottom end of the positioning rod separates from the movable block.

[0010] Furthermore, a second guide plate is installed at an angle at the top of the second storage cavity, and the end of the second guide plate near the support roller is higher than the other side. A gap is reserved between the lowest end of the second guide plate and the side wall of the second storage cavity to accommodate the passage of the steel pipe.

[0011] Furthermore, a movable baffle is movably provided on one side of the second storage chamber.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the steel pipe outer circle grinding machine can automatically feed and automatically unload the ground steel pipe by setting up a feeding plate, lifting parts, support rollers and elastic support mechanism, which has a high degree of automation and improves work efficiency.

[0017] Please see Figure 1-7 An embodiment of the present invention provides a steel pipe outer circle grinding machine, including a working chamber 1, and the working chamber 1 is divided into a feeding chamber 101, a first storage chamber 102 and a second storage chamber 103 by a partition. The working chamber 1 is a cuboid structure with an open top. The feeding chamber 101 is located between the first storage chamber 102 and the second storage chamber 103. The first storage chamber 102 is used to store steel pipes to be ground, and the second storage chamber 103 is used to store steel pipes that have been ground. The feeding chamber 101 is used to convey the steel pipes to be ground one by one upwards.

[0018] The bottom end of the first storage chamber 102 is inclinedly provided with a first guide plate 1021. A feed inlet 1022 communicating with the inside of the feeding chamber 101 is provided through the side wall of one side of the first storage chamber 102. A drive roller 5 and a support roller 7 are rotatably installed above the feeding chamber 101. The drive roller 5 and the support roller 7 are parallel to each other. A rotary drive component 6 is provided at one end of the drive roller 5. The rotary drive component 6 can be a motor, which is installed on the outside of the working chamber 1. When the steel pipe to be ground is placed at the top, it can drive the steel pipe to rotate for all-round grinding.

[0019] The support roller 7 is horizontally movably mounted on one side of the drive roller 5 via an elastic support mechanism 8. The elastic support mechanism 8 is used to push the support roller 7 to move closer to the drive roller 5. Both ends of the support roller 7 are connected to movable blocks 701 via rotating shafts. The movable blocks 701 are horizontally slidably connected to the working cavity 1. Specifically, the movable blocks 701 are slidably mounted outside the working cavity 1, and a strip-shaped through hole is provided through the side wall of the working cavity 1 to accommodate the horizontal sliding of the rotating shaft. (See reference...) Figure 5The elastic support mechanism 8 includes a first fixed plate 801 fixed on the outer wall of the working chamber 1 and a first elastic support member 802 disposed between the movable block 701 and the first fixed plate 801. The first elastic support member 802 is used to push the movable block 701 to move horizontally towards the side closer to the drive roller 5. The first elastic support member 802 can be a spring and is disposed between the first fixed plate 801 and the movable block 701. Further, a guide rod 803 is horizontally fixed on the side of the first fixed plate 801 close to the movable block 701. A through hole matching the guide rod 803 is provided through the movable block 701. The guide rod 803 passes through the interior of the first elastic support member 802 and is slidably connected to the movable block 701. During the grinding operation, under the elastic support of the first elastic support member 802, the support roller 7 is pushed closer to the drive roller 5 to provide support for the steel pipe to be ground.

[0020] Each side of the working cavity 1 near the movable block 701 is provided with a positioning mechanism 11 for locking the movable block 701. (See reference) Figure 5 The positioning mechanism 11 includes a second fixing plate 1101 fixed to the outer wall of the working chamber 1, a positioning rod 1102 slidably disposed on the second fixing plate 1101, a limiting plate 1104 fixed to the top of the positioning rod 1102, and a second elastic support member 1103 that pushes the positioning rod 1102 downward. The positioning rod 1102 is located above the movable block 701, and the top of the movable block 701 is provided with a positioning hole that matches the positioning rod 1102. A baffle is fixed to the lower part of the outer peripheral wall of the positioning rod 1102. The second elastic support member 1103 is specifically a spring, which is sleeved on the outside of the positioning rod 1102. During assembly, the top of the spring abuts against the second fixing plate 1101, and the bottom end abuts against the baffle on the positioning rod 1102. Both ends of the feeding plate 9 are provided with A mounting plate 903 is provided. A strip-shaped through hole is provided on the side wall of the working cavity 1 to accommodate the vertical movement of the mounting plate 903. The mounting plate 903 extends through the strip-shaped through hole to the outside of the working cavity 1. The mounting plate 903 is located below the limiting plate 1104. A push rod 904 is vertically fixed at the top of the mounting plate 903. The push rod 904 is used to push the limiting plate 1104 upward when the feeding plate 9 rises to feed material, so that the bottom end of the positioning rod 1102 is separated from the movable block 701. When the steel pipe is being ground, the positioning rod 1102 is inserted into the positioning hole at the top of the movable block 701 to fix the support roller 7 and improve the stability of the support roller 7. When material needs to be fed, the feeding plate 9 drives the push rod 904 to move upward in advance to lift the positioning rod 1102, so as to facilitate the horizontal movement of the movable block 701.

[0021] A support frame 2 is fixed to the top of the working chamber 1. In this embodiment, the support frame 2 has an inverted U-shaped structure. Furthermore, to reduce environmental pollution, an openable protective cover can also be provided at the top of the working chamber 1. A grinding mechanism 4 is movably installed on the side of the bottom of the support frame 2 near the first storage chamber 102 via a linear drive mechanism 3. The linear drive mechanism 3 is used to drive the grinding mechanism 4 to slide back and forth horizontally along the axial direction parallel to the drive roller 5. In this embodiment, the grinding mechanism 4 is located above the drive roller 5. During grinding, the grinding mechanism 4 is tilted above the steel pipe, and the drive roller 5 is located above the first storage chamber 102, which facilitates the rolling of the steel pipe after subsequent grinding into the second storage chamber 103. (See reference...) Figure 7 The grinding mechanism 4 includes a bracket 401, a first grinding wheel 402 and a second grinding wheel 403 coaxially rotatably mounted on both sides inside the bracket 401, and a drive mechanism 404 for driving the first grinding wheel 402 and the second grinding wheel 403 to rotate. A slider 405 connected to the linear drive mechanism 3 is mounted on the bracket 401. In this embodiment, the slider 405 is movably mounted on the top of the bracket 401. The first grinding wheel 402 can be a flap wheel, and the second grinding wheel 403 can be a resin-thickened grinding wheel. The drive mechanism 404 can be a belt pulley structure, including a belt pulley fixed to the first grinding wheel. The driven wheel on the shaft of the first grinding wheel 402 and the second grinding wheel 403, the drive wheel installed above the driven wheel, the motor that drives the drive wheel to rotate, and the belt that connects the drive wheel and the driven wheel drive the first grinding wheel 402 and the second grinding wheel 403 to rotate synchronously, so as to achieve two grindings of the steel pipe. The linear drive mechanism 3 can be a lead screw installed horizontally at the bottom of the support frame 2 and a motor that drives the lead screw to rotate. The slider 405 is threadedly connected to the lead screw. The rotation of the lead screw can drive the slider 405 to move horizontally. Furthermore, the linear drive mechanism 3 can also be set as an electric telescopic rod, cylinder or other linear drive component as needed.

[0022] The top of the bracket 401 is equipped with an inverted U-shaped connecting plate 406. The connecting plate 406 and the slider 405 are connected by a linear drive 407. The linear drive 407 is used to push the bracket 401 and the slider 405 to move up and down relative to each other. The linear drive 407 can be a cylinder, which is vertically fixed to the top of the slider 405. The output end is fixedly connected to the connecting plate 406. By extending and retracting the linear drive 407, the bracket 401 is driven to move up and down. The up and down positions of the first grinding wheel 402 and the second grinding wheel 403 can be adjusted so that they are in close contact with the surface of the steel pipe.

[0023] Inside the feeding chamber 101, a feeding plate 9 is vertically mounted via a lifting component 10. This plate vertically conveys the steel pipes that roll to the top of the feeding plate 9 to the tops of the drive roller 5 and the support roller 7. The lifting component 10 can be any type of cylinder, electric telescopic rod, etc. It is vertically installed at the bottom of the working chamber 1, with its output end extending into the feeding chamber 101 and fixedly connected to the feeding plate 9. (See reference...) Figure 4 The feeding plate 9 includes a top plate 902 horizontally disposed inside the feeding chamber 101 and a baffle plate 901 vertically fixed to the side of the top plate 902 near the feed inlet 1022. The bottom end of the feeding chamber 101 is provided with a through hole to accommodate the baffle plate 901 extending to the outside of the feeding chamber 101. The baffle plate 901 is used to block the feed inlet 1022. When the top plate 902 moves to the lowest end of the feeding chamber 101, the steel pipe inside the first storage chamber 102 passes through the feed inlet 1022 and rolls to the top of the top plate 902. When the lifting component 10 drives the feeding plate 9 to rise, the baffle plate 901 abuts against the side of the feed inlet 1022 to block it.

[0024] The second guide plate 1031 is installed at an incline at the top of the second storage cavity 103, and the end of the second guide plate 1031 near the support roller 7 is higher than the other side. A gap is reserved between the lowest end of the second guide plate 1031 and the side wall of the second storage cavity 103 to accommodate the passage of the steel pipe. The ground steel pipe first falls to the top of the second guide plate 1031 and then to the bottom of the second storage cavity 103, which can play a buffering role.

[0025] Furthermore, a movable baffle 12 is movably provided on one side of the second storage chamber 103. The bottom two sides of the movable baffle 12 are hinged to the bottom two sides of the working chamber 1. The movable baffle 12 can be fixedly connected to the working chamber 1 by a buckle (not shown in the figure). During normal operation, the movable baffle 12 is closed. When it is necessary to take out the steel pipe, the movable baffle 12 is flipped to the horizontal position to act as a guide plate, which is attached to the top of the receiving frame to facilitate the removal of the steel pipe after grinding.

[0026] Working principle: During operation, the steel pipe to be ground is first placed inside the first storage chamber 102. The steel pipe rolls down along the first guide plate 1021, passing through the feed inlet 1022 one by one into the feeding chamber 101. The lifting component 10 drives the feeding plate 9 to move upward until the steel pipe moves to the bottom of the drive roller 5 and the support roller 7. At this time, the top rod 904 abuts against the limit plate 1104 in advance, pushing the limit plate 1104 to move upward, driving the positioning rod 1102 to move upward and separate from the movable block 701. The second elastic support 803 is in a compressed state and continues to be conveyed upward, pushing the support roller 7 to move away from the drive roller 5. At this time, the movable block 701 compresses the first elastic support 802. When the steel pipe moves to the drive roller 5... After the top of the support roller 7, the feeding plate 9 moves down to reset, and the support roller 7 also resets under the elastic support of the first elastic support member 802. When the top rod 904 separates from the limit plate 1104, the second elastic support member 1103 pushes the positioning rod 1102 down to reset and inserts it into the positioning hole at the top of the movable block 701 to lock the movable block 701. The rotation drive member 6 drives the drive roller 5 to rotate, and then drives the steel pipe to rotate. The linear drive mechanism 3 drives the grinding mechanism 4 to move horizontally along the length of the steel pipe to grind the outer circle. After the grinding is completed, the feeding plate 9 moves up to continue feeding. Before the steel pipe is fed to the top of the drive roller 5 and the support roller 7, the ground steel pipe is pushed to roll into the second storage cavity 103 to realize automatic feeding.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
