Description

Technical Field

[0001] The invention relates to the technical field of alloy tube production, in particular to large-diameter alloy tube processing equipment and a processing technology. Background Art

[0002] Large diameter alloy pipes, as the name implies, refer to alloy steel pipes with large diameter, high toughness and good corrosion resistance. Such steel pipes are usually composed of specific alloy elements and base metals, and are formed into pipes with excellent performance through specific smelting and processing technology. Large diameter alloy pipes have excellent mechanical properties and tensile strength, can withstand various mechanical loads, and are ideal for load-bearing structures and transportation pipelines.

[0003] In the production of large-diameter alloy tubes, after the tubes are melt-cast and formed, their surfaces need to be polished. During the polishing process, the tubes are conveyed by conveyor rollers and then fixed. First, the clamps of the specified tubes will block part of the tube surface and cannot be polished. After polishing the tube surface, the clamps need to be removed and the unpolished areas need to be polished again. However, in the process of clamping, disassembling and fixing, the axis of the tube body is easily tilted, resulting in an insufficiently fine polishing effect, and it is inconvenient to cooperate with the conveying device to realize continuous processing such as conveying, fixing and polishing. Summary of the invention

[0004] The purpose of the present invention is to provide a large-diameter alloy pipe processing equipment and a processing technology to solve the problems raised in the above background technology.

[0007] Preferably, a support rod passes through and is slidably connected to the inner side of the fixed plate, and an arc block is fixedly connected to one end of the support rod close to the axis of the fixed plate, and a push plate is fixedly connected to the bottom end of the support rod. When the movable ring moves, the tube body is driven to move together through the arc block. When the movable ring moves a certain distance, the circular plate will contact the surface of the positioning plate, so that the circular plate pushes the insertion rod to insert into the fixed plate, and the circular plate will push the hinge rod to rotate, so that the hinge rod pushes the push plate downward through the hinge block, and the push plate passes through the fixed plate and is slidably connected, and a spring 2 is fixedly connected between the push plate and the inner wall of the fixed plate.

[0008] Preferably, a hinge block is fixedly connected to the surface of the push plate, a hinge rod passes through and is hinged to the inner side of the hinge block, an end of the hinge rod away from the hinge block passes through and is hinged to a circular plate, an insertion rod is fixedly connected to the surface of the circular plate, the insertion rod passes through the fixed plate and is slidably connected, and a spring three is fixedly connected between the circular plate and the fixed plate.

[0009] Preferably, a shaft is fixedly connected to the inner side of the fixing plate, and the shaft passes through and is rotatably connected to a rotating rod.

[0010] Preferably, one end of the rotating rod passes through and is hinged to the limit block. After the push plate moves downward a certain distance, it contacts the limit block and forces the limit block to rotate a short distance, causing the limit block to shrink briefly. At the same time, the limit block will pull the rotating rod to rotate and pull the L-shaped rod to compress spring four. After the bottom end of the push plate exceeds the bottom surface of the limit block, spring four pushes the L-shaped rod back to cause the rotating rod to rotate again and push the limit block back to push the push plate, so that the push plate is limited by the limit block. The other end of the rotating rod passes through and is hinged to the L-shaped rod, and the surface of the movable ring is fixedly connected to a fixed block.

[0011] Preferably, the L-shaped rod passes through the fixed block and is slidably connected to the fixed block. A spring four is fixedly connected between the inner part of the L-shaped rod and the surface of the fixed block. After the push plate moves downward a certain distance, it contacts the limit block and forces the limit block to rotate a short distance, causing the limit block to shrink temporarily. At the same time, the limit block will pull the rotating rod to rotate and pull the L-shaped rod to compress the spring four.

When the cylinder pushes the moving seat to drive the moving ring to move, the guide groove inside the moving seat will move with the moving seat. Since the positioning plate is fixedly connected to the inner wall of the body, the guide groove will resist the sliding of the toggle block in the guide groove when moving, and then the toggle turntable is rotated, and the slide rod will drive the push rod to clamp the locking block to the tube body.

[0014] Preferably, a turntable is rotatably connected to the inner side of the positioning plate, an arc groove is provided on the surface of the turntable, the slide rod is inserted into the inner side of the arc groove, a toggle block is fixedly connected to the bottom surface of the turntable, and the toggle block passes through the movable groove and is inserted into the guide groove.

[0015] A processing technology for large-diameter alloy pipe processing equipment, the process comprising the following steps:

[0016] S1. Insert the large-diameter alloy tube into the inner side of the machine body, and push the arc block to compress the second spring when inserting the tube body, so that the second spring always pushes the push plate to make the support rod push the arc block to clamp the tube body, and place the middle end of the tube body above the connecting table, and then install the grinding sheet on the processing table;

[0017] S2, start cylinder 1, so that cylinder 1 pushes the mounting seat up to make the grinding sheet fit with the surface of the tube body, and then start cylinder 2 to push the moving seat to slide on the inner side of the machine body. When the moving seat is pushed by cylinder 2, it will drive the moving ring to move together, and when the moving ring moves, it will drive the tube body to move together through the arc block. When the moving ring moves a certain distance, the circular plate will contact the surface of the positioning plate, so that the circular plate pushes the insertion rod to insert into the fixed plate, and the circular plate will push the hinged rod to rotate, so that the hinged rod pushes the push plate downward through the hinged block, and after the push plate moves downward a certain distance, it will contact the limit block and force the limit block to rotate The limit block contracts briefly after a short distance, and the limit block pulls the rotating rod to rotate and pulls the L-shaped rod to compress the spring four. After the bottom end of the push plate exceeds the bottom surface of the limit block, the spring four pushes back the L-shaped rod to rotate the rotating rod again and push the limit block back to the push plate, so that the push plate is limited by the limit block, so that the push plate pulls the arc block through the support rod and no longer fits the pipe body, and then the arc block will not drive the pipe body to retreat when the cylinder two is started to reset. By repeatedly starting the cylinder two, the large-diameter alloy pipe is driven to move in one direction each time the moving ring follows the moving seat, and the distance of each movement is the same, which plays the effect of fixed-distance conveying of pipes.

[0018] S3. When the cylinder pushes the moving seat to drive the moving ring to move, the guide groove inside the moving seat will move with the moving seat. Since the positioning plate is fixedly connected to the inner wall of the body, the guide groove will resist the sliding of the toggle block in the guide groove when moving, and then the toggle turntable will rotate, and the slide rod will drive the push rod to clamp the locking block to clamp the tube body;

[0019] Step 4: Start motor 2 to enable the grinding disc on motor 2 to grind the tube body.

[0020] Compared with the prior art, the present invention provides a large-diameter alloy tube processing equipment and processing technology, which has the following beneficial effects:

[0021] 1. The large-diameter alloy pipe processing equipment and processing technology, after the bottom end of the push plate exceeds the bottom surface of the limit block, the spring four pushes back the L-shaped rod to rotate the rotating rod again and pushes back the limit block to push the push plate, so that the push plate is limited by the limit block, so that the push plate pulls the arc block through the support rod and no longer fits the pipe body, and then starts the cylinder two to reset so that the arc block will not drive the pipe body to retreat, and by repeatedly starting the cylinder two, each time when the moving ring follows the moving seat to move, it drives the large-diameter alloy pipe to move in one direction, and the distance of each movement is the same, which plays the effect of fixed-distance conveying of pipes.

[0022] 2. The large-diameter alloy tube processing equipment and processing technology can fix the tube body by contracting the locking block to the middle of the positioning plate after the tube body is transported at a fixed distance, and the locking block in the symmetrical body can keep the axis of both ends of the tube body consistent. The stability of the tube body during grinding and the axis will not be offset when the locking block is fixed.

[0023] 3. The large-diameter alloy tube processing equipment and processing technology, under the mirror setting of the linkage part in the symmetrical body, can ensure that the linkage part in one side of the body is transported and the linkage part in the other side of the body is pulled, and in the process of transporting and pulling, temporary fixation will not cause the axis of the tube body to shift, and at the same time, it can also ensure the stability of the tube during transportation and processing.

A support rod 28 passes through the inner side of the fixed plate 27 and is slidably connected. An arc block 29 is fixedly connected to one end of the support rod 28 close to the axis of the fixed plate 27. A push plate 210 is fixedly connected to the bottom end of the support rod 28. When the movable ring 26 moves, the tube body is driven to move together through the arc block 29. When the movable ring 26 moves a certain distance, the circular plate 214 will contact the surface of the positioning plate 31, so that the circular plate 214 pushes the insertion rod 215 to insert into the fixed plate 27, and the circular plate 214 will push the hinge rod 213 to rotate, so that the hinge rod 213 pushes the push plate 210 to move downward through the hinge block 212. The push plate 210 passes through the fixed plate 27 and is slidably connected. A spring 211 is fixedly connected between the push plate 210 and the inner wall of the fixed plate 27. The surface of the push plate 210 is fixedly connected with a hinge block 212, and a hinge rod 213 is passed through and hinged to the inner side of the hinge block 212, and a circular plate 214 is passed through and hinged to the end of the hinge rod 213 away from the hinge block 212, and an insertion rod 215 is fixedly connected to the surface of the circular plate 214, and the insertion rod 215 passes through the fixed plate 27 and is slidably connected, and a spring 3 216 is fixedly connected between the circular plate 214 and the fixed plate 27.

A spring 222 is fixedly connected between the inner part of the L-shaped rod 220 and the surface of the fixed block 221. After the push plate 210 moves downward for a certain distance, it contacts the limit block 219 and forces the limit block 219 to rotate a short distance, causing the limit block 219 to shrink temporarily. At the same time, the limit block 219 pulls the rotating rod 218 to rotate and pulls the L-shaped rod 220 to compress the spring 222. There are three groups of arc blocks 29, and the inner sides of the three groups of arc blocks 29 are penetrated by elastic rings 223, and arc springs 224 are fixedly connected between every two groups of arc blocks 29.

When the cylinder 10 pushes the moving seat 22 to drive the moving ring 26 to move, the guide groove 25 on the inner side of the moving seat 22 will move with the moving seat 22. Since the positioning plate 31 is fixedly connected to the inner wall of the body 1, the guide groove 25 will resist the sliding of the toggle block 310 in the guide groove 25 when moving, and then the toggle dial 38 is rotated, and the slide bar 36 will drive the push rod 35 to clamp the locking block 37 to the tube body.

[0035] A processing technology for large-diameter alloy pipe processing equipment, the process comprising the following steps:

[0036] S1. Insert the large-diameter alloy tube into the inner side of the machine body 1, and push the arc block 29 to compress the spring 211 when inserting the tube body, so that the spring 211 always pushes the push plate 210 to make the support rod 28 push the arc block 29 to clamp the tube body, and place the middle end of the tube body above the connecting platform 13, and then install the grinding sheet on the processing table;

[0037] S2. Start the cylinder 10, so that the cylinder 10 pushes the mounting seat 9 to rise so that the grinding sheet fits the surface of the tube body, and then start the cylinder 21 to push the moving seat 22 to slide on the inner side of the body 1. When the moving seat 22 is pushed by the cylinder 21, it will drive the moving ring 26 to move together, and when the moving ring 26 moves, it will drive the tube body to move together through the arc block 29. When the moving ring 26 moves a certain distance, the circular plate 214 will contact the surface of the positioning plate 31, so that the circular plate 214 pushes the insertion rod 215 to insert into the fixed plate 27, and the circular plate 214 will push the hinge rod 213 to rotate, so that the hinge rod 213 pushes the push plate 210 to move downward through the hinge block 212. After the push plate 210 moves downward a certain distance, it will contact the limit block 219 and force the limit block 219 to rotate The limit block 219 contracts briefly after a short distance, and the limit block 219 pulls the rotating rod 218 to rotate and pulls the L-shaped rod 220 to compress the spring four 222. After the bottom end of the push plate 210 exceeds the bottom surface of the limit block 219, the spring four 222 pushes back the L-shaped rod 220 to rotate the rotating rod 218 and push the limit block 219 back to push the push plate 210, so that the push plate 210 is limited by the limit block 219, so that the push plate 210 pulls the arc block 29 through the support rod 28 and no longer fits the pipe body, and then the arc block 29 will not drive the pipe body to retreat when the cylinder 21 is started to reset. By repeatedly starting the cylinder 21, it is achieved that each time the moving ring 26 moves with the moving seat 22, the large-diameter alloy pipe is driven to move in one direction, and the distance of each movement is the same, which plays the effect of fixed-distance conveying of pipes;

[0038] S3. When the cylinder 10 pushes the moving seat 22 to drive the moving ring 26 to move, the guide groove 25 on the inner side of the moving seat 22 will move with the moving seat 22. Since the positioning plate 31 is fixedly connected to the inner wall of the body 1, the guide groove 25 will resist the sliding of the toggle block 310 in the guide groove 25 when moving, and then the toggle plate 38 will rotate, and the slide rod 36 will drive the push rod 35 to make the locking block 37 clamp the tube body;

[0039] Step 4: Start the motor 2 12 to enable the grinding disc on the motor 2 12 to grind the pipe body.

When the moving seat (22) is pushed by the cylinder 2 (21), it drives the moving ring (26) to move together, and when the moving ring (26) moves, it drives the tube body to move together through the arc block (29). When the moving ring (26) moves a certain distance, the circular plate (214) will contact the surface of the positioning plate (31), so that the circular plate (214) pushes the insertion rod (215) to be inserted into the fixed plate (27). When the cylinder 2 (21) is started again to reset, the arc block (29) will not drive the tube body to retreat; S3. When the cylinder (10) pushes the movable seat (22) to drive the movable ring (26) to move, the guide groove (25) on the inner side of the movable seat (22) will move along with the movable seat (22). Since the positioning plate (31) is fixedly connected to the inner wall of the body (1), the guide groove (25) will resist the sliding of the toggle block (310) located in the guide groove (25) when moving, thereby toggling the rotating plate (38) to rotate, and the sliding rod (36) will drive the push rod (35) to make the locking block (37) clamp the tube body; Step 4: Start the motor 2 (12) to make the grinding disc on the motor 2 (12) grind the pipe body.
