Description

Technical Field

[0001] The present invention relates to the technical field of metal pipe processing, and specifically to a metal pipe forming device with a polishing function. Background Art

[0002] Metal pipes are one of the important raw materials for the development of the national economy. They are a relatively economical type of steel product and have been widely used in industries such as chemical engineering, petroleum, electric power, machinery, and coal. Metal pipes have a hollow cross-section and are widely used as pipes for transporting fluids, such as pipes for transporting oil, natural gas, coal gas, water, and certain solid materials. Compared with solid pipes, hollow pipes are lighter in weight when the bending and torsional strength are the same, and are an economical cross-sectional material. They are widely used in the manufacture of structural parts and mechanical components, which can improve the material utilization rate, save materials and processing time. In particular, industrially developed countries attach great importance to the production and trade of metal pipes;

[0003] After the existing metal pipes are processed, their surfaces are usually rough and they are directly stacked. When needed later, the metal pipes are subjected to fine polishing treatment, which increases the processing time before use and thus affects the work efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a metal pipe forming device with a polishing function to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A metal pipe forming device with a polishing function includes a metal pipe processing device and also includes a polishing device. The polishing device is connected to the metal pipe processing device. The polishing device includes a machine body. Moving grooves are symmetrically arranged on both sides of the machine body. Moving blocks are arranged in the moving grooves. A spray pipe is arranged between the two moving blocks. A polishing plate is arranged in the inner wall of the machine body.

[0007] Preferably, racks are arranged on the side walls of the moving grooves. A first motor is arranged in the moving blocks. The driving shaft of the first motor is connected to a gear. The gear meshes with the rack. A rotating ring is arranged on the side of the moving block close to the inside of the machine body.

[0008] Before the metal pipe enters the machine body for polishing treatment, the moving block drives the rotating ring to be located at the top of the moving groove. After the metal pipe is placed between the two moving blocks, the controller controls the first motor to start. The driving shaft of the first motor drives the gear to rotate. After the gear rotates, it meshes with the rack, and then the moving block moves along the side of the moving groove, so that the moving block moves to the bottom of the moving groove, and then the metal pipe moves into the inside of the machine body.

[0009] Preferably, a number of telescopic clamping blocks are provided on the rotating ring. The telescopic clamping blocks are driven by electric cylinders. A micro motor is provided on one side of the telescopic clamping blocks. A magnetic conductor is provided inside the rotating ring, and electromagnetic coils are provided around the rotating ring.

[0010] When the two telescopic clamping blocks extend under the action of the electric cylinders and extend into the inner diameter of the metal tube to clamp the metal tube, the controller then controls the micro motor and the electromagnetic coils to start. The micro motor drives the telescopic clamping blocks to rotate, and the telescopic clamping blocks drive the metal tube to perform a self-rotation movement. After the electromagnetic coils are powered on, they drive the rotating ring to rotate. After the rotating ring rotates, it drives a number of metal tubes to rotate. At this time, the metal tube revolves around the axis of the rotating ring.

[0011] Preferably, a hydraulic cylinder is provided inside the machine body. The push rod of the hydraulic cylinder is connected to a polishing plate. The polishing plate is composed of a water baffle, a contact plate and a debris flow plate. The water baffle is provided on one side of the machine body close to the moving groove, and the contact plate is located between the water baffle and the debris flow plate.

[0012] After the axis of the rotating ring coincides with the axis of the machine body, the controller controls the hydraulic cylinder to start. The hydraulic cylinder pushes the polishing plate to move. The polishing plate moves towards the side close to the metal tube. When the inner wall of the polishing plate contacts the outer wall of the metal tube, the polishing plate stops rotating. Subsequently, under the combination of self-rotation and revolution of the metal tube, it contacts the surface of the contact plate for polishing treatment.

[0013] Preferably, a number of flow grooves are provided on the surface of the contact plate, and a number of blocking strips are provided on the surface of the debris flow plate. One end of the flow groove communicates with the water baffle, and the other end of the flow groove communicates with the debris flow plate. The polishing plate is arc-shaped.

[0014] Part of the water sprayed from the spray nozzles is blocked by the water baffle, so that the water can only move from the water baffle to the contact plate. The water on the water baffle flows into the flow grooves, and the water on the contact plate dissipates the heat generated by polishing. At the same time, the debris generated on the contact plate is washed into the flow grooves and conveyed from the flow grooves to the debris flow plate. When the water and debris mixture flows to the debris flow plate, it is blocked by a number of blocking strips, so that the debris is retained on the surface of the debris flow plate, thus achieving the effect of debris separation.

[0015] Preferably, a number of spray nozzles are symmetrically provided on one side of the spray pipe close to the polishing plate, and a number of air blowing ports are provided at the bottom of the spray pipe. The spray nozzles are connected to a water pump through pipes, and the air blowing ports are connected to an air pump through pipes.

[0016] The water pump extracts the external water source and sprays it through the spray nozzle onto the polishing plate. While the sprayed water cools the polishing plate, it flushes away the debris generated during polishing. The air pump extracts the external air. Part of the gas is transported through the pipeline to the airbag pad, and the other part of the gas is blown towards the side close to the polishing tank through the air outlet. As a result, the flow rate of the blown air current increases, causing the air pressure inside the machine body and in the polishing tank to decrease. The gas outside the machine body will then enter the machine body under the action of the air pressure, thereby suppressing the water mist and debris generated by the spraying inside the machine body. Moreover, the gas sprayed from the air outlet can also play a role in cooling and heat dissipation.

[0017] Preferably, a polishing tank is provided at the bottom of the machine body. One side of both sides of the polishing tank is the output port, and the other side is the input port. The height in the middle of the polishing tank is lower than the heights on both sides. The output port side of the polishing tank is connected to a suction pump.

[0018] After the outer wall of the metal pipe is polished, the two telescopic clamping blocks on the lowest end side of the rotating ring contract under the action of the electric cylinder. Then the metal pipe disengages from the support of the telescopic clamping blocks, and then the metal pipe drops from the machine body into the polishing tank. The metal pipe is then transported through the gap between the two flow debris plates.

[0019] When the metal pipe drops into the polishing tank, the suction pump extracts the water and polishing material in the storage cavity, transports them through the pipeline to the polishing tank, and flows from the output port to the input port. Since the height in the middle of the polishing tank is lower than the heights on both sides, the mixture of water and polishing material moves radially along the middle of the polishing tank. When the metal pipe drops into the polishing tank, part of the mixture of water and polishing material can directly enter the inside of the metal pipe, thereby flushing and polishing the inner wall of the metal pipe, thus realizing the inner wall polishing treatment of the metal pipe. After the metal pipe has been flushed and polished for a period of time, only water is transported from the output port to the polishing tank to flush away the remaining polishing material in the metal pipe and keep the inside of the metal pipe clean.

[0020] Preferably, two conveyor belts are symmetrically arranged at the bottom of the polishing tank. The surface of the conveyor belt is provided with friction lines. The conveyor belt is driven by a driving motor. The surface of the conveyor belt is provided with a number of holes. A storage cavity is provided at the bottom of the conveyor belt.

[0021] The mixture of water and polishing material on the outer wall of the metal pipe then drops into the storage cavity through the holes on the conveyor belt for recycling. However, the driving motor drives the conveyor belt to rotate, causing the two conveyor belts to drive in opposite directions. When another metal pipe drops into the polishing tank, the metal pipe will, under the influence of gravity, squeeze the previously dropped metal pipe to one side, causing the previously dropped metal pipe to be squeezed onto the surface of the conveyor belt, so that the conveyor belt drives the metal pipe to move towards the side of the pipe discharge groove.

[0022] Preferably, two pipe discharge grooves are symmetrically arranged on both sides of the polishing tank, and the pipe discharge grooves communicate with the inside of the machine body.

[0023] Preferably, an airbag pad is arranged on one side of the polishing plate close to the conveyor belt. An air outlet is arranged on one side of the airbag pad, and the air outlet is arranged in the flow groove. The distance between the polishing plate and the conveyor belt is less than the diameter of the metal pipe.

[0024] The conveyor belt conveys the metal pipe polished inside the diameter from the polishing tank to the side close to the pipe discharge groove. Since the distance between the polishing plate and the conveyor belt is less than the diameter of the metal pipe, when the metal pipe moves between the polishing plate and the conveyor belt, the metal pipe squeezes the airbag pad on the polishing plate, so that the metal pipe will not slide due to the influence of the polishing tank. Furthermore, the metal pipe can be smoothly conveyed into the pipe discharge groove and finally conveyed out. When the airbag pad is squeezed by the metal pipe, the internal gas can be conveyed from the air outlet, and the gas flows along the flow groove through the air outlet, thereby blowing the debris attached in the flow groove.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] The rotating ring drives the metal pipe to rotate and revolve around the axis of the machine body, so that the metal pipe contacts the surface of the polishing plate under the combination of rotation and revolution, and the outer wall polishing treatment operation of the metal pipe is completed. At the same time, the water and polishing material mixture is radially conveyed by the polishing tank, so that the mixture flows directly into the inside of the metal pipe, and the mixture flushes and polishes the inner wall of the metal pipe. Moreover, when the metal pipe is conveyed to the pipe discharge groove, the metal pipe squeezes the airbag pad, so that the extruded gas sprays towards the flow groove, further promoting the discharge of materials during polishing.

A number of holes are provided on the surface of the conveyor belt 18, and a storage cavity 19 is provided at the bottom of the conveyor belt 18.

[0045] As a specific embodiment of the present invention, an airbag pad 146 is provided on one side of the polishing plate 14 close to the conveyor belt 18. An air outlet is provided on one side of the airbag pad 146, and the air outlet is arranged in the flow groove 144. The distance between the polishing plate 14 and the conveyor belt 18 is less than the diameter of the metal pipe.

[0046] The working principle of the present invention:

[0047] Before the metal pipe enters the body 1 for polishing treatment, the moving block 12 drives the rotating ring 15 to be located at the top of the moving groove 11. After the metal pipe is placed between the two moving blocks 12, the controller controls the first motor to start. The drive shaft of the first motor drives the gear to rotate. After the gear rotates, it meshes with the rack, and then the moving block 12 moves along the side of the moving groove 11, so that the moving block 12 moves to the bottom of the moving groove 11, and then the metal pipe moves into the body 1.

[0048] After the two telescopic clamping blocks 16 extend under the action of the electric cylinder and extend into the inner diameter of the metal pipe to clamp the metal pipe, the controller then controls the start of the micro motor and the electromagnetic coil respectively. The micro motor drives the telescopic clamping block 16 to rotate, and the telescopic clamping block 16 drives the metal pipe to rotate. After the electromagnetic coil is powered on, it drives the rotating ring 15 to rotate. After the rotating ring 15 rotates, it drives several metal pipes to rotate. At this time, the metal pipe revolves around the axis of the rotating ring 15;

[0049] After the axis of the rotating ring 15 coincides with the axis of the machine body 1, the controller controls the hydraulic cylinder to start. The hydraulic cylinder pushes the polishing plate 14 to move. The polishing plate 14 moves toward the side close to the metal pipe. When the inner wall of the polishing plate 14 contacts the outer wall of the metal pipe, the polishing plate 14 stops rotating. Subsequently, under the combination of the rotation and revolution of the metal pipe, it contacts the surface of the contact plate 142 for polishing treatment;

[0050] Part of the water sprayed from the spray port 131 is blocked by the water baffle 141, so that the water can only move from the water baffle 141 to the contact plate 142. The water on the water baffle 141 flows to the flow groove 144, and the water on the contact plate 142 dissipates the heat generated by polishing. At the same time, the debris generated on the contact plate 142 is washed into the flow groove 144 and conveyed from the flow groove 144 to the flow debris plate 143. When the water and debris mixture flows to the flow debris plate 143, it is blocked by several blocking strips 145, so that the debris is retained on the surface of the flow debris plate 143, thus achieving the effect of debris separation;

[0051] The water pump extracts the external water source and sprays it through the spray port 131 to the polishing plate 14, so that the sprayed water cools the polishing plate 14 while washing away the debris generated by polishing. The air pump extracts the external air. Part of the gas is conveyed through the pipeline to the airbag pad 146, and the other part of the gas is blown toward the side close to the polishing groove 17 through the air outlet 132. Then the flow rate of the blown air flow is accelerated, so that the air pressure in the machine body 1 and the polishing groove 17 is reduced, and the gas outside the machine body 1 will enter the machine body 1 under the action of the air pressure, thereby pressing the water mist and debris generated by spraying in the machine body 1, and the gas sprayed from the air outlet 132 can also play the role of cooling and heat dissipation;

[0052] When the outer wall of the metal pipe is polished, the two telescopic clamping blocks 16 on the bottommost side of the rotating ring 15 contract under the action of the electric cylinder. Then the metal pipe is separated from the support of the telescopic clamping block 16, and then the metal pipe falls from the machine body 1 to the polishing groove 17, and the metal pipe is then conveyed through the gap between the two flow debris plates 143;

[0053] When the metal pipe drops into the polishing tank 17, the suction pump extracts the water and polishing material in the storage cavity 19, transports them through the pipeline to the polishing tank 17, and makes them flow from the output port to the input port. Since the height in the middle of the polishing tank 17 is lower than that on both sides, the mixture of water and polishing material moves radially along the middle of the polishing tank 17. When the metal pipe drops into the polishing tank 17, a part of the mixture of water and polishing material can directly enter the inside of the metal pipe, thereby flushing and polishing the inner wall of the metal pipe, so as to realize the inner wall polishing treatment of the metal pipe. After the metal pipe has been flushed and polished for a period of time, only water is transported from the output port to the polishing tank 17 to flush the residual polishing material in the metal pipe and keep the inside of the metal pipe clean;

[0054] The mixture of water and polishing material on the outer wall of the metal pipe drops into the storage cavity 19 through the holes on the conveyor belt 18 for recycling. However, the driving motor drives the conveyor belt 18 to rotate, so that the two conveyor belts 18 are driven to the opposite sides. When another metal pipe drops into the polishing tank 17, the metal pipe will squeeze the previously dropped metal pipe to one side under the influence of gravity, so that the previously dropped metal pipe is squeezed onto the surface of the conveyor belt 18, so that the conveyor belt 18 drives the metal pipe to move towards the side of the pipe discharging groove 20;

[0055] The conveyor belt 18 transports the metal pipe polished inside diameter from the polishing tank 17 to the side close to the pipe discharging groove 20. Since the distance between the polishing plate 14 and the conveyor belt 18 is smaller than the diameter of the metal pipe, when the metal pipe moves between the polishing plate 14 and the conveyor belt 18, the metal pipe squeezes the air bag pad 146 on the polishing plate 14, so that the metal pipe will not slide due to the influence of the polishing tank 17. Furthermore, the metal pipe can be smoothly transported into the pipe discharging groove 20 and finally transported out. The air bag pad 146 is squeezed by the metal pipe, and then the internal gas can be transported from the air outlet. The gas flows along the flow groove 144 through the air outlet, and then blows the debris attached in the flow groove 144.

[0056] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
