Description

Technical Field

[0001] The invention belongs to the technical field of cutting equipment, in particular to a composite pipe processing equipment. Background Art

[0002] Composite pipe is a pipe made of two or more different materials through a specific process. It combines the advantages of multiple materials and has good comprehensive properties, such as high strength, corrosion resistance, wear resistance, thermal insulation, etc. In recent years, with the continuous advancement of industrial technology and the increasing requirements of various industries for pipe performance, composite pipes have been widely used in many fields such as construction, petroleum, chemical industry, municipal engineering, machinery manufacturing, etc.

[0003] In the process of composite pipe processing, it is necessary to compound the processed tube blank with other materials. The composite device can be used to compound the tube blank with other materials. After the compounding is completed, a composite pipe with a layered structure of different materials is formed, which can then be cut according to the required length of the pipe. Since composite pipes are usually composed of layered structures of different materials, the bonding strength between the layers may be limited. During the cutting process, since the cutter gradually cuts into the composite pipe, the cutter acts on the layered structure of different materials. The cutting force of the cutter easily causes separation between the layers. This delamination and peeling phenomenon will seriously affect the integrity and performance of the pipe and reduce its use value. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] Embodiment 1: Figures 1 to 11 As shown, a composite pipe processing device according to the present invention comprises a cutting device; the cutting device comprises a cutting chamber 1; a support leg is installed at the bottom of the cutting chamber 1; Two opposite driving rings 11 are rotatably installed in the cutting chamber 1; the two driving rings 11 are provided with circular grooves 12 on opposite sides of the cutting chamber 1; The two driving rings 11 are fixedly connected to the circular rings 13 on opposite sides, and the circular rings 13 slide in the circular grooves 12; The end surfaces of the two driving rings 11 on opposite sides are fixedly connected by a plurality of connecting rods 111; a belt groove is provided on the outer ring surface of one of the driving rings 11, and a belt 14 is rotatably connected in the belt groove; A first motor 15 is installed above the cutting chamber 1, and a pulley is installed on the driving shaft of the first motor 15, and the other side of the belt 14 is connected to the pulley; It should be noted that the above is the basic structure of the existing composite pipe cutting equipment. The difference between this embodiment and the prior art is that a round rod 2 is fixedly connected between two adjacent connecting rods 111; a rotating plate 21 is rotatably connected to the round rod 2; an end surface of the rotating plate 21 away from the round rod 2 is fixedly connected to an n-type plate 22; a cutter 23 is rotatably provided in the n-type plate 22 via a rotating shaft; The rotating plate 21 is rotatably connected to a first hydraulic cylinder 24, and the other end of the first hydraulic cylinder 24 is rotated on one of the connecting rods 111; The left and right end surfaces of the cutting chamber 1 are both equipped with evenly arranged electric push rods 16, and the side of the electric push rods 16 close to the circular groove 12 is fixedly connected with a clamping plate 17; A cutting auxiliary mechanism is provided on the right side of the cutting device, and the cutting auxiliary mechanism is used to assist the cutting device in cutting the composite pipe 18; In this embodiment, the auxiliary cutting mechanism includes a base 3; a slide seat 31 is slidably connected to the base 3; a second hydraulic cylinder 32 is installed on the base 3, and the extended end of the second hydraulic cylinder 32 is installed on the slide seat 31; A turntable 33 is rotatably mounted on one end surface of the slide 31 facing the cutting chamber 1; a second motor 34 is mounted on one end surface of the slide 31 away from the cutting chamber 1, and the second motor 34 is used to drive the turntable 33 to rotate; Two insertion rods 35 are fixedly installed on one end surface of the rotating disk 33 facing the cutting chamber 1, and the two insertion rods 35 are arranged on the rotating disk 33 up and down; The two insertion rods 35 are provided with a pressure shaft 36 at one end close to the cutting chamber 1, and both ends of the pressure shaft 36 are tapered; the pressure shaft 36 is screwed on the insertion rod 35 by means of a thread; in the initial state, the pressure shaft 36 located at the top is concentrically arranged with the circular groove 12 on the cutting chamber 1; The diameter of the pressure bearing shaft 36 is the same as the diameter of the composite pipe 18 to be cut; In this embodiment, a first annular groove 37 is formed on the outer circumferential surface of the pressure bearing shaft 36, and the first annular groove 37 cooperates with the cutter 23; The width of the first annular groove 37 is greater than the width of the cutter 23; the inner circle of the first annular groove 37 is located in the inner wall of the pressure-bearing drawer and a second annular groove 38 is opened, and the second annular groove 38 is connected to the first annular groove 37; The width of the second annular groove 38 is smaller than the width of the first annular groove 37; Specifically, when the pipes are compounded and become the compound pipe 18, the compound pipe 18 will be cut according to the required length. When cutting, the pipe is first transported to the cutting device by the conveying roller, and the second hydraulic cylinder 32 is controlled to contract. During the contraction of the second hydraulic cylinder 32, the slide 31 is pushed and pulled to move to the left on the base 3, and the slide 31 drives the second motor 34, the turntable 33 and the two insertion rods 35 to move to the left. During the movement of the two insertion rods 35 to the left, the insertion rod 35 located at the top drives the pressure shaft 36 from the circular groove 12 on the right to enter the cutting chamber 1, and is located between the two driving rings 11, and the first annular groove 37 is aligned with the cutter 23, and the insertion rod 35 located at the bottom is also located. The rod 35 will drive the pressure shaft 36 to move to the position below the cutting chamber 1, and at the same time, the second hydraulic cylinder 32 will shrink to the limit state. When the composite pipe 18 enters the cutting chamber 1, the composite pipe 18 will first enter the cutting chamber 1 from the left circular groove 12, and then the composite pipe 18 will gradually contact the pressure shaft 36. When the pressure shaft 36 gradually overlaps with the moving composite pipe 18, the pressure shaft 36 will gradually insert into the inner cavity of the composite pipe 18, and the composite pipe 18 will continue to move under the drive of the conveying roller. At the same time, the composite pipe 18 will gradually move toward the position of the slide seat 31 along the pressure shaft 36. When the composite pipe 18 moves to the required length position, the composite pipe 18 is controlled to stop moving, and then the composite pipe 18 can be cut; More specifically, when cutting the composite pipe 18, firstly, the electric push rods 16 on both sides of the cutting chamber 1 are controlled to extend, and the extended electric push rods 16 will push the clamping plate 17 to approach the composite pipe 18 and clamp the composite pipe 18, and then the first hydraulic cylinder 24 is controlled to contract, and the contracted first hydraulic cylinder 24 will pull the rotating plate 21 to rotate along the round rod 2, and at the same time, it will drive the n-type plate 22 and the cutter 23 to gradually approach the composite pipe 18. When the cutter 23 is in contact with the composite pipe 18, the first motor 15 is controlled to rotate, and the first motor 15 will drive the belt 14 to rotate through the pulley, and the belt 14 will drive one of the driving rings 11 to rotate counterclockwise, and the circular ring 13 on the driving ring 11 will rotate along the circular groove 12. Since the two driving rings 11 are connected by a connecting rod 111, The two driving rings 11 will be driven to rotate, and the rotating driving ring 11 will drive the round rod 2, the first hydraulic cylinder 24, the n-type plate 22 and the cutter 23 to rotate. The rotating cutter 23 will rotate counterclockwise along the composite pipe 18. The circularly rotating cutter 23 can gradually cut the composite pipe 18. At the same time, during the rotation of the cutter 23, the first hydraulic cylinder 24 is gradually controlled to gradually shrink, thereby driving the rotating plate 21 to continue to rotate along the round rod 2, thereby driving the cutter 23 to gradually deepen the cutting depth of the composite pipe 18. During the cutting of the composite pipe 18, due to the existence of the pressure shaft 36, the composite pipe 18 can be supported from the inside of the composite pipe 18. When the composite pipe 18 is cut, the cut composite pipe 18 can be unloaded. Further, when the composite pipe 18 is cut, the first hydraulic cylinder 24 is controlled to restore to the initial state, thereby driving the n-type plate 22 and the cutter 23 away from the composite pipe 18, and then the electric push rod 16 on the right side of the cutting chamber 1 is controlled to restore to the initial state. At this time, the clamping plate 17 on the right side of the cutting chamber 1 no longer clamps the composite pipe 18, and then the second hydraulic cylinder 32 is controlled to extend, thereby pushing the slide 31 to move rightward on the base 3, and at the same time, the rotating disk 33, the plug rod 35 and the pressure shaft 36 are driven to move rightward, and the pressure shaft 36 drives the cut composite pipe 18 to move to the right. Move right, when the end face of the composite pipe 18 after cutting moves to the right side of the cutting chamber 1, the two pressure shafts 36 are also located on the right side of the cutting chamber 1, and then the second motor 34 is controlled to rotate, and the second motor 34 will drive the turntable 33 and the two insertion rods 35 to rotate 180 degrees, and the pressure shaft 36 originally located at the top will drive the cut composite pipe 18 to rotate to the bottom, and then the cut composite pipe 18 is pushed down from the pressure shaft 36 below through the unloading support mechanism, and the slide seat 31 is controlled to move to the left as a whole, so that the composite pipe 18 can continue to be cut; Furthermore, since the pressure-bearing shaft 36 is provided with a first annular groove 37, when the cutter 23 cuts off the composite pipe 18, the cutter 23 will enter the first annular groove 37, and the blade on the cutter 23 will enter the second annular groove 38. Since the depth of the first annular groove 37 is limited, when the positions of the two sides of the blade on the cutter 23 contact the bottom of the first annular groove 37, the cutter 23 cannot move downward, and the blade of the cutter 23 is located in the second annular groove 38, so that the blade of the cutter 23 can be protected and prevented from directly acting on the pressure-bearing shaft 36. By inserting the pressure-bearing shaft 36 into the composite pipe 18, the pressure-bearing shaft 36 can be used to support the inside of the composite pipe 18. When the cutter 23 rotates to cut the composite pipe 18, the pressure-bearing shaft 36 supporting the composite pipe 18 can limit the layered structures of different materials from the inside, thereby preventing the cutting force from acting on the layered structure of the inner layer of the composite pipe 18 during the process of the cutter 23 gradually cutting into the composite pipe 18, thereby causing the inner layer structure and the outer layer structure of the composite pipe 18 to separate, thereby affecting the integrity and performance of the composite pipe 18 and reducing its use value; at the same time, since the pressure-bearing shaft 36 can support the composite pipe 18, when cutting the composite pipe 18, it can be avoided that the composite pipe 18 is deformed when the cutter 23 gradually applies pressure to the composite pipe 18. When the pipe is deformed, the incision of the composite pipe 18 will be uneven.

[0020] Embodiment 2: A material unloading support mechanism is installed on the two insertion rods 35, and the material unloading support mechanism is used to support the insertion rods 35 and unload the cut composite pipe 18. The material unloading support mechanism includes a limit plate 4; the two insertion rods 35 pass through the limit plate 4 and are slidably connected to the limit plate 4; the outer ring of the limit plate 4 is provided with a limit ring 41, and the limit plate 4 is located in the limit ring 41 and is rotatably connected to the inner ring surface of the limit ring 41; A driving plate 42 is fixedly mounted on the top of the limiting ring 41; a guide rail 43 is arranged above the driving plate 42; and a side of the guide rail 43 close to the cutting chamber 1 is fixedly mounted on the cutting chamber 1; The guide rail 43 passes through the slide seat 31 on one side thereof and extends to the right side of the slide seat 31 . The guide rail 43 passes through one side of the slide seat 31 and is slidably connected to the slide seat 31 . An electric slider 44 is slidably connected in the guide rail 43; the driving plate 42 is fixedly connected to the electric slider 44; In this embodiment, a slide bar 45 is slidably connected between the two insertion rods 35 and located on the limit plate 4; The two sliding rods 45 are fixedly connected to a push plate 46 on one end surface facing the cutting chamber 1, and a spring is connected between the push plate 46 and the limit plate 4; Specifically, when the cut pipe follows the pressure shaft 36 to rotate to the bottom, the electric slider 44 is controlled to move along the guide rail 43 to the side of the cutting chamber 1, and the electric slider 44 will drive the driving plate 42 to move. The moving driving plate 42 will drive the limiting ring 41 and the limiting plate 4 rotating in the limiting ring 41 to move toward the cutting chamber 1 position, and the limiting plate 4 will move along the two plug rods 35. At the same time, the moving limiting plate 4 will push the composite pipe 18 on the lower plug rod 35 to move to the left and gradually break away from the plug rod 35. When the limiting plate 4 pushes the cut composite pipe 18 to move to the left, the push plate 46 will also contact the end of the composite pipe 18. When the limiting plate 4 moves to the position of the pressure shaft 36, the cut composite pipe 18 can be pushed off the pressure shaft 36 under the push of the push plate 46, and the fallen composite pipe 18 will be collected. More specifically, when the cut composite pipe 18 is separated from the pressure-bearing shaft 36 below, the pressure-bearing shaft 36 located above is controlled to extend again between the two driving rings 11 in the cutting chamber 1, and the electric slider 44 is controlled to drive the driving ring 11 and the driving plate 42 to move to the circular groove 12 position. Since the guide rail 43 passes through one side of the slide seat 31 and is slidably connected to the slide seat 31, when the slide seat 31 moves to the left or right, it will move along the guide rail 43; since the electric slider 44 lifts the limit ring 41 and the limit plate 4, the lifted limit plate 4 can pull up the insertion rod 35, so as to support the insertion rod 35, thereby preventing the insertion rod 35 from being in a downward tilted state under its own gravity, thereby preventing the pressure-bearing shaft 36 from tilting, causing the center of the pressure-bearing shaft 36 to be misaligned with the center of the circular groove 12, thereby preventing the pressure-bearing shaft 36 from being easily inserted into the composite pipe 18; Furthermore, when the composite tube 18 gradually moves to the right along the pressure-bearing shaft 36, the electric slider 44 is controlled to gradually move to the right, and the electric slider 44 will drive the limit plate 4 and the limit ring 41 to move to the right. When the distance between the limit plate 4 and the cutter 23 is the length that the composite tube 18 needs to be cut, the electric slider 44 is controlled to stop moving, and the composite tube 18 is controlled to continue moving. Then the composite tube 18 can be cut. Since the limit plate 4 rotates in the limit ring 41, when the turntable 33 drives the two plug rods 35 to rotate, the rotating plug rods 35 will drive the limit plate 4 to rotate in the limit ring 41.

[0021] Embodiment 3: A plurality of slide grooves 25 are provided on the two end surfaces at the bottom of the n-type plate 22; a slide plate 26 is slidably connected in each of the slide grooves 25, and a spring is connected between the slide plate 26 and the bottom of the slide groove 25; the slide plate 26 extends to the bottom of the n-type plate 22 and is located on both sides of the cutter 23; the bottom end surface of the slide plate 26 is a semicircular surface; In this embodiment, each of the two side end surfaces of the slide plate 26 parallel to the cutter 23 is rotatably connected with a pressing rod 27; The diameter of the pressing rod 27 is larger than the diameter of the semicircular surface at the bottom of the slide plate 26; the side of the pressing rod 27 close to the cutter 23 is in contact with the side of the cutter 23; In this embodiment, a curved scraper 28 is fixedly connected to the end surface of each slide plate 26 away from the first hydraulic cylinder 24, and the curved scraper 28 is in contact with the surface of the pressing rod 27; Specifically, since a slide plate 26 is slidably connected in the slide groove 25 at the bottom of the n-type plate 22, and a pressing rod 27 is rotatably connected to the slide plate 26, when the rotating plate 21 drives the n-type plate 22 to approach the position of the composite tube 18, a plurality of pressing rods 27 will contact the outer ring surface of the composite tube 18. When the pressing rods 27 contact the outer ring surface of the composite tube 18, the pressing rods 27 will slide into the slide groove 25 and compress the spring due to the obstruction of the composite tube 18. When the cutter 23 contacts the surface of the composite tube 18, the slide plate 26 stops sliding into the slide groove 25. At this time, a plurality of pressing rods 27 are distributed on both sides of the cutter 23 and are in contact with the composite tube 18. More specifically, when the driving ring 11 drives the n-type plate 22 and the cutter 23 to rotate along the composite tube 18, the slide plate 26 will also drive the multiple pressing rods 27 to rotate along the composite tube 18. During the rotation of the pressing rods 27 along the composite tube 18, the pressing rods 27 will rotate themselves and press the positions on both sides of the cutter 23. During the cyclic rotation of the cutter 23 along the composite tube 18, the first hydraulic cylinder 24 will pull the n-type plate 22 and the cutter 23 to rotate, thereby driving the cutter 23 to gradually deepen the cutting depth of the composite tube 18. At the same time, since the distance between the n-type plate 22 and the composite tube 18 becomes smaller, the slide plate 26 will continue to slide into the slide groove 25 until the composite tube 18 is cut off. By providing a pressing rod 27 that rotates with the cutter 23, and the pressing rod 27 rotates itself during the process of revolving along the composite tube 18, the surface of the composite tube 18 on both sides of the cutting position of the cutter 23 can be pressed, so that the layered structure of the outer layer of the composite tube 18 can be stabilized, and it is prevented that when the cutter 23 cuts the composite tube 18, the cutting force will act on the layered structure of the outer layer of the composite tube 18, thereby causing the inner layer structure and the outer layer structure of the composite tube 18 to separate; Furthermore, since the pressing rods 27 on both sides of the cutter 23 are in contact with the end surfaces on both sides of the cutter 23, the trajectory of the cutter 23 cutting the composite tube 18 can be limited during the rotation of the cutter 23, thereby preventing the cutter 23 from being offset when cutting the composite tube 18, thereby causing an incomplete incision of the composite tube 18; since the arc-shaped scraper 28 fixedly connected to the slide plate 26 is in contact with the surface of the pressing rod 27, the pressing rod 27 will pass through the arc-shaped scraper 28 when it rotates, and the arc-shaped scraper 28 can scrape the surface of the passing pressing rod 27, thereby avoiding the presence of impurities on the pressing rod 27, which affects the pressing effect of the pressing rod 27 on the composite tube 18.
