Description

Technical Field

[0001] The present application relates to the technical field of polishing equipment, and in particular to a steel pipe polishing equipment. Background Art

[0002] After processing and forming, steel pipes often need to be polished on the outer surface. The polished steel pipes have a bright and smooth outer surface, which can meet the processing and application requirements of some precision machinery.

[0003] Most existing steel pipe polishing equipment includes two sets of rotating and oppositely arranged grinding wheels, with a gap between the two sets of grinding wheels for the steel pipe to enter and enable the grinding wheels to polish the outer surface of the steel pipe. After the operator manually puts the steel pipe between the two sets of grinding wheels, the operator can apply force to the grinding wheels along the extension direction of the steel pipe, so that the steel pipe can pass through the gap between the two sets of grinding wheels while the grinding wheels are grinding the steel pipe, thereby completing the grinding of the steel pipe by the grinding wheels.

[0004] However, the method in which the operator manually feeds the steel pipe into the gap between the two sets of grinding wheels and then uses the grinding wheels to grind the steel pipe is too cumbersome and labor-intensive. Moreover, in the process of grinding the steel pipe with the grinding wheels, the operator is required to manually apply a thrust to the steel pipe so that the steel pipe can pass through the gap between the two sets of grinding wheels, which is even more inconvenient. There is also the phenomenon that the speed of the steel pipe passing through the gap between the two sets of grinding wheels is too fast or too slow due to uneven human force and different speeds, which can easily affect the grinding accuracy of the steel pipe and increase the defective rate of steel pipe grinding. Summary of the invention

[0005] Purpose of the invention: The present application provides a steel pipe polishing device, which aims to improve the technical problem that the steel pipe needs manual operation during the grinding process, which is inconvenient to operate and easily affects the grinding accuracy of the steel pipe.

[0006] Technical solution: The present application provides a steel pipe polishing device, comprising a polishing body, which is used to polish the outer surface of the steel pipe; a plurality of groups of pipe support frames, the top walls of all the pipe support frames are used to receive the steel pipe; the top walls of each group of the pipe support frames are inclined along a first direction, and the top walls of the pipe support frames are provided with a pipe blocking block at the lowest horizontal point for blocking the movement of the steel pipe; a pipe jacking mechanism is arranged below the pipe support frames, and is used to lift the steel pipe on the pipe support frames onto the pipe blocking block; a conduit mechanism is arranged on the pipe support frames, and is used to receive the steel pipe passing through the pipe blocking block, and is capable of transporting the steel pipe along the first direction; a pipe transport mechanism is arranged on one side of all the pipe support frames, and is used to receive the steel pipe transported by the conduit mechanism, and is capable of sending the steel pipe to the polishing body for polishing.

[0007] By adopting the above technical scheme, the pipe support frame is used to support the steel pipe to be polished, and the pipe blocking block is used to block the steel pipe, thereby reducing the phenomenon that the steel pipe directly separates from the pipe support frame along the first direction; the pipe jacking mechanism can lift the steel pipe on the pipe support frame onto the pipe blocking block, and the steel pipe can automatically enter the guide tube mechanism along the pipe blocking block under the action of gravity; after the guide tube mechanism receives the steel pipe, it can send the steel pipe to the transport mechanism, and finally, the steel pipe is sent into the polishing machine body through the transport mechanism for polishing; this process effectively reduces the tedious problems of manual operation through the automated transfer of steel pipes, and, through the automated transportation of steel pipes and the delivery of steel pipes into the polishing machine body, the uniformity of the speed at which the steel pipe enters the polishing machine body can be guaranteed, which helps to ensure the accuracy of the polishing of the steel pipe by the polishing machine body and ensure the yield rate of the polishing of the steel pipe.

[0025] The embodiment of the present application discloses a steel pipe polishing device.

[0026] The following is combined with Figure 1-5This application is described in further detail.

[0027] Reference Figure 1 A steel pipe polishing device includes a polishing machine body 1, a pipe support frame 2, a pipe jacking mechanism 3, a conduit mechanism 4 and a transport mechanism 5. The polishing machine body 1 can be a polishing machine for polishing the outer surface of a steel pipe; the transport mechanism 5 is located at one end of the polishing machine body 1 in the length direction, and the extension direction of the transport mechanism 5 is the same as the extension direction of the polishing mechanism; the number of pipe support frames 2 can be multiple groups, and the multiple groups of pipe support frames 2 are arranged in an array along the length direction of the transport mechanism 5 on one side of the width direction of the transport mechanism 5 to jointly bear the steel pipe to be polished. The pipe jacking mechanism 3 is located below the pipe support frame 2, and the conduit mechanism 4 is arranged on one side of the pipe support frame 2 and between the pipe support frame 2 and the transport mechanism 5. The pipe jacking mechanism 3 can lift the steel pipe on the pipe support frame 2, and the lifted steel pipe can automatically enter the transport mechanism 5 through the conduit mechanism 4. Finally, the steel pipe is sent to the polishing machine body 1 through the transport mechanism 5 for polishing.

[0028] Reference Figure 1 The pipe support frame 2 can be a steel frame that supports a horizontal steel pipe through two vertical steel pipes. The two vertical steel pipes of the pipe support frame 2 are fixed to the ground by bolts, and the horizontal steel pipe of the pipe support frame 2 is used to receive the steel pipe. In addition, the top of the pipe support frame 2 is inclined along the first direction 8. In this embodiment, the first direction 8 is the direction from the top of the transportation management mechanism 5 to the transportation management mechanism 5. Specifically, the horizontal height of the top of the pipe support frame 2 away from one end of the transportation management mechanism 5 is located at the horizontal height of the top of the pipe support frame 2 close to one end of the transportation management mechanism 5. After the top wall of the pipe support frame 2 receives the steel pipe, the steel pipe can slide toward the transportation management mechanism 5 under the action of gravity.

[0029] Reference Figure 2 In order to reduce the phenomenon that the steel pipe slides directly toward the transport management mechanism 5 along the first direction 8 on the pipe support frame 2, the pipe support frame 2 is welded with a pipe blocking block 21 at the lowest point of the horizontal position of the top wall along the first direction 8. The height of the pipe blocking block 21 is greater than the outer diameter of the steel pipe, so as to block the steel pipe on the pipe support frame 2 and reduce the phenomenon that the steel pipe slides directly from the pipe support frame 2 along the first direction 8.

[0030] Reference Figure 2 The pipe jacking mechanism 3 includes a lifting cylinder 31, a connecting plate 32, a push rod 33 and a top plate 34, wherein the number of the lifting cylinders 31 is the same as the number of the pipe support frames 2, and a group of lifting cylinders 31 is fixed to the ground below a group of pipe support frames 2 by bolts. The connecting plate 32 is welded to the output ends of all the lifting cylinders 31 in the horizontal direction, and the number of the push rods 33 and the top plate 34 corresponds to the number of the lifting cylinders 31.

[0031] Reference Figure 2, all the push rods 33 are vertically welded to the top wall of the connecting plate 32, and the top plate 34 is obliquely welded along the first direction 8 to the end of the push rod 33 away from the connecting plate 32. In this embodiment, the length dimension of the top plate 34 is smaller than the outer diameter dimension of the steel pipe. When the lifting cylinder 31 is in the standby state, the top plate 34 is located below all the steel pipes. After the lifting cylinder 31 extends outwardly to the output end, the top plate 34 can abut against the steel pipe closest to the pipe block 21 and lift the steel pipe to above the pipe block 21. After the steel pipe is lifted to above the pipe block 21, the steel pipe can move toward the transportation management mechanism 5 along the length direction of the pipe block 21 under the action of gravity.

[0032] Reference Figure 3 The conduit mechanism 4 is used to receive the steel pipe dropped from the pipe blocking block 21 on one side of the pipe support frame 2, and the conduit mechanism 4 can also transport the steel pipe along the first direction 8 so that the steel pipe is stably placed on the transport mechanism 5. The conduit mechanism 4 includes a connecting shaft 41, a plurality of conduit frames 42 and a driving assembly 43, wherein the connecting shaft 41 passes through all the pipe support frames 2, and the connecting shaft 41 is rotatably connected to each group of pipe support frames 2 through a bearing.

[0033] Reference Figure 3 In this embodiment, a group of pipe racks 42 is arranged between every two groups of pipe racks 2, and each group of pipe racks 42 includes a first connecting plate 421, a second connecting plate 422 and a sensing block 423. Among them, the first connecting plate 421 can be a whole steel plate, or a combined steel plate formed by welding or bolting a plurality of steel plates end to end. In this embodiment, the first connecting plate 421 includes two steel plates that are abutted end to end and connected by bolts. The end of the first connecting plate 421 close to the connecting shaft 41 is welded obliquely on the side wall of the connecting shaft 41, and the angle between the first connecting plate 421 and the horizontal plane is smaller than the angle inclined along the first direction 8 under the horizontal plane, so that the first connecting plate 421 can receive the steel pipe dropped from the pipe block 21 in a nearly horizontal state, and can also make the steel pipe dropped on the first connecting plate 421 continue to move downward along the inclination angle of the first connecting plate 421 itself.

[0034] Reference Figure 3 The second connecting plate 422 is vertically welded to the end of the first connecting plate 421 away from the connecting shaft 41. In this embodiment, the second connecting plate 422 and the first connecting plate 421 are L-shaped. The second connecting plate 422 can receive the steel pipe moving on the first connecting plate 421 at the end of the first connecting plate 421 away from the connecting shaft 41, thereby reducing the phenomenon of the steel pipe directly detaching from the first connecting plate 421.

[0035] Reference Figure 3The sensing block 423 can be a steel block with a touch sensor inside. The sensing block 423 is glued to the side wall of the second connecting plate 422 facing the connecting shaft 41, and the sensing block 423 is electrically connected to the driving assembly 43 through the PLC controller. The driving assembly 43 includes a first guide plate 431, a driving cylinder 432 and a side rotation assembly 433, wherein one end of the first guide plate 431 close to the connecting shaft 41 is welded obliquely to the side wall of the connecting shaft 41, and the first guide plate 431 is parallel to the first connecting plate 421.

[0036] Reference Figure 3 The driving cylinder 432 is rotatably arranged on the ground through the side rotation assembly 433, and the driving cylinder 432 is located between the pipe support frame 2 and the pipe transport mechanism 5. The side rotation assembly 433 includes two side plates 4331 parallel to each other, and a rotating rod 4332 rotatably arranged between the two side plates 4331. The side plates 4331 are fixed to the ground by bolts, and the end wall of the driving cylinder 432 away from the output end is welded to the side wall of the rotating rod 4332.

[0037] Reference Figure 3 The output end of the rotation-driving cylinder 432 is rotatably connected to the end of the first guide plate 431 away from the connecting shaft 41 through a hinge. When the output end of the rotation-driving cylinder 432 is extended outward, the output end of the rotation-driving cylinder 432 applies an upward thrust to the end of the first guide plate 431 away from the connecting shaft 41, and the first guide plate 431 can be parallel to the first connecting plate 421. At this time, the first connecting plate 421 can receive the steel pipe and move the steel pipe along the tilting direction of the first connecting plate 421 until the steel pipe moves to the sensing block 423. When the steel pipe touches the induction block 423, the drive cylinder 432 shrinks the output end. At this time, the end of the first guide plate 431 away from the connecting shaft 41 can fall downward after losing the thrust of the output end of the drive cylinder 432. The bottom of the drive cylinder 432 rotates counterclockwise through the rotating rod 4332, and the end of the first guide plate 431 close to the connecting shaft 41 is fixedly connected to the connecting shaft 41. Therefore, in the process of the end of the first guide plate 431 away from the connecting shaft 41 moving downward, the connecting shaft 41 can also rotate counterclockwise following the movement of the first guide plate 431, thereby causing the first connecting plate 421 to move downward until it is parallel to the first direction 8. After the first connecting plate 421 is parallel to the first direction 8, the second connecting plate 422 and the end of the first connecting plate 421 close to the second connecting plate 422 can move to the bottom of the transport management mechanism 5, thereby causing the steel pipe to be transported from between the first connecting plate 421 and the second connecting plate 422 to the transport management mechanism 5.

[0038] Reference Figure 4 and Figure 5The transport management mechanism 5 is used to receive the steel pipe and can deliver the steel pipe to the polishing machine body 1 for polishing. The transport management mechanism 5 includes a main rotating assembly 51, a guide tube assembly 52 and a driving belt 53. Among them, the main rotating assembly 51 also includes a main rotating motor 511, a mounting seat 512, a main rotating rod 513 and a plurality of first guide wheels 514, wherein the mounting seat 512 can be a bearing seat, and the mounting seat 512 and the main rotating motor 511 are relatively fixed on the ground by bolts. One end of the main rotating rod 513 in the length direction is coaxially connected to the output end of the main rotating motor 511 through a flange, and the other end of the main rotating rod 513 in the length direction is installed on the mounting seat 512. After the main rotating motor 511 rotates forward or reverses the output end, the main rotating rod 513 can follow the rotation direction of the output end of the main rotating motor 511 and rotate in a clockwise direction or a counterclockwise direction.

[0039] Reference Figure 5 All the first guide wheels 514 are spaced and equidistantly welded on the main rotating rod 513 along the length direction of the main rotating rod 513. During the rotation of the main rotating rod 513, all the first guide wheels 514 can rotate synchronously with the rotation of the main rotating rod 513.

[0040] Reference Figure 5 The duct assembly 52 includes a plurality of support plates 521, a guide rod 522, a second guide wheel 523 and a duct wheel 524. In this embodiment, a duct assembly 52 is arranged between each two adjacent groups of first guide wheels 514, and the support plate 521 is welded to the main guide rod 513 along the vertical direction.

[0041] Reference Figure 5 The guide rods 522 are rotatably arranged on the side walls on both sides of the width direction of each support plate 521 through bearings in the horizontal direction, the second guide wheel 523 and the duct wheel 524 are welded on each guide rod 522 at intervals, and the duct wheel 524 is located between the second guide wheel 523 and the support plate 521.

[0042] Reference Figure 5 In this embodiment, a group of first guide wheels 514 and a group of second guide wheels 523 correspond to each other, and the driving belt 53 is tautly sleeved on the corresponding first guide wheels 514 and second guide wheels 523. One end of each group of conduit wheels 524 away from the main rotating rod 513 protrudes above the support plate 521, and a conduit channel 6 that can just allow the steel pipe to pass through is left between the two groups of conduit wheels 524 located on both sides of the support plate 521 in the width direction, and the conduit channel 6 is located above the support plate 521.

[0043] Reference Figure 4 and Figure 5, after the driving and rotating cylinder 432 contracts its output end, the second connecting plate 422 and the first connecting plate 421 can move below the conduit passage 6. During this process, the end of the second connecting plate 422 near the first connecting plate 421 moves downward from the gap between the adjacent support plates 521, and the steel pipes on the first connecting plate 421 and the second connecting plate 422 can fall between two adjacent sets of conduit wheels 524 and stay in the conduit passage 6. The main rotating motor 511 rotates its output end, the main rotating rod 513 rotates following the output end of the main rotating motor 511, and during the process of the first guide wheel 514 rotating following the main rotating rod 513, it drives the driving belt 53 to rotate, and the driving belt 53 can in turn drive the second guide wheel 523 to rotate; the rotating second guide wheel 523 can in turn drive the guiding rod 522 and the conduit wheels 524 to rotate, so that under the state that the conduit wheels 524 on both radial sides of the steel pipe in the conduit passage 6 are constantly rotating, the steel pipe can follow the rotation of the conduit wheels 524 and move along the length direction of the main rotating rod 513, and then enter the polishing body 1 for polishing treatment.

[0044] Referring to Figure 4 and Figure 5 , in order to improve the phenomenon that the steel pipe with too long length dimension is prone to position deviation when entering the polishing body 1, the pipe conveying mechanism 5 further includes a pipe guiding assembly 7, and the pipe guiding assembly 7 further includes multiple sets of lifting cylinders 71, a pipe supporting box 72 and a pipe guiding frame 73. Among them, the number of the lifting cylinders 71 can be three groups, and the three groups of lifting cylinders 71 are fixed on the ground by bolt arrays and are located between the polishing body 1 and the mounting seat 512.

[0045] Referring to Figure 5 , the pipe supporting box 72 is welded to the output ends of all the lifting cylinders 71 in the horizontal direction, the pipe guiding frame 73 can be a V-shaped frame or a U-shaped frame or a C-shaped frame. In this embodiment, the pipe guiding frame 73 is a V-shaped frame, the pipe guiding frame 73 is welded to the pipe supporting box 72 in the horizontal direction, the pipe guiding frame 73 extends along the length direction of the pipe supporting box 72, and the inner cavity of the pipe guiding frame 73 can just be adapted for the steel pipe to pass through. After the steel pipe comes out of the conduit passage 6, it can enter the pipe guiding frame 73, and finally, enter the polishing body 1, thus effectively ensuring the position stability of the steel pipe when entering the polishing body 1.

[0046] The implementation principle of a steel pipe polishing device according to an embodiment of the present application is as follows: the jacking cylinder 31 extends its output end, and the top plate 34 can abut against the steel pipe closest to the pipe blocking block 21 and jack the steel pipe above the pipe blocking block 21. After the steel pipe is jacked above the pipe blocking block 21, the steel pipe can move along the length direction of the pipe blocking block 21 under the action of gravity and fall onto the first connecting plate 421.

[0047] The steel pipe moves toward the second connecting plate 422 along the inclined direction of the first connecting plate 421 until it touches the sensing block 423. After the steel pipe touches the sensing block 423, the driving cylinder 432 shrinks the output end. At this time, the end of the first guide plate 431 away from the connecting shaft 41 can fall downward after losing the thrust of the output end of the driving cylinder 432. The bottom of the driving cylinder 432 rotates in the counterclockwise direction through the rotating rod 4332, and the connecting shaft 41 can also rotate in the counterclockwise direction following the movement of the first guide plate 431, thereby causing the first connecting plate 421 to move downward until it is parallel to the first direction 8. After the first connecting plate 421 is parallel to the first direction 8, the second connecting plate 422 and the end of the first connecting plate 421 close to the second connecting plate 422 can move to the bottom of the conduit wheel 524, thereby causing the steel pipe to be transferred from between the first connecting plate 421 and the second connecting plate 422 to the conduit channel 6.

[0048] Then, the main rotating motor 511 rotates the output end, and the main rotating rod 513 rotates following the output end of the main rotating motor 511. The first guide wheel 514 drives the driving belt 53 to rotate while following the rotation of the main rotating rod 513, and the driving belt 53 can also drive the second guide wheel 523 to rotate.
