Description

Technical Field

[0001] The invention belongs to the technical field of resin pipe production equipment, and specifically refers to a pipe body surface rounding extruder for resin pipe production. Background Art

[0002] Resin tube refers to a high-pressure hose that uses a plastic extruded hose as the inner core and is reinforced with high-strength industrial fibers or steel wires through weaving or winding. The tube body is generally divided into three layers: inner hose layer, skeleton reinforcement layer and outer rubber layer. Resin tube has the advantages of high pressure bearing, light weight, high temperature resistance, good flame retardancy and good elasticity. It is widely used in petroleum, chemical industry, engineering machinery manufacturing, coal mining, shipbuilding, aviation, automobile and medical equipment industries. In order to ensure the quality of resin tube production, it is usually necessary to round the surface of the resin tube.

[0003] The prior art discloses a tube surface rounding extruder for resin tube production, and the authorization publication number is CN213006530U. This application effectively solves the problems of time-consuming and labor-intensive operation, difficulty in operation and low production efficiency of the prior art rounding extruder by setting three groups of sliding grooves and three groups of rounding rollers. However, the rounding extruder in this application is composed of multiple groups of rollers, and the accuracy between the multiple groups of rollers is difficult to adjust. It is relatively complicated for production personnel to adjust the equipment, and the operation of multiple groups of rollers is noisy. Moreover, during the tube rounding process of the tube body, the pressure of the rounding extruder in this application is concentrated in the area where the rollers contact the tube body, resulting in local stress concentration in the tube body, increasing the risk of deformation and damage of the tube. In addition, the rollers in this application cannot adjust the rotation speed for tubes of different materials and thicknesses, reducing the applicability of the rounding extruder. Finally, the auxiliary equipment of the rounding extruder in the prior art is separately set, and for the rounding of the surfaces of resin tubes of different diameters, appropriate devices need to be replaced or adjusted separately, reducing the flexibility of the rounding extruder. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a pipe surface rounding extruder for the production of resin pipes with a rounding component, a radius control component and an auxiliary component, which effectively solves the problems of the pipe surface rounding extruder for the production of resin pipes on the market, such as complex adjustment of the surface rounding for different pipe diameters, large noise pollution, easy stress concentration to damage the pipe body, rigid adjustment of auxiliary equipment and inability to round different pipes.

[0005] The technical solution adopted by the present invention is as follows: A tube surface rounding extruder for resin tube production includes a fixed bracket, an outer shell, a rounding component, a radius control component and an auxiliary component. The outer shell is fixedly arranged on the fixed bracket, the rounding component is arranged in the outer shell, the radius control component is fixedly arranged on the fixed bracket, and the auxiliary component is arranged in the outer shell. The auxiliary component is located at the inlet of the rounding extruder. The fixed bracket supports the upper components. After the auxiliary component preliminarily fixes the position of the resin tube, the rounding component heats and rounds the surface of the resin tube. The radius control component adjusts the inner diameter size of the rounding component to adapt to the rounding work of the surface of resin tubes with different diameters.

[0006] Furthermore, the rounding assembly includes a conductor segment, a power transmission assembly, an arc magnet, a rounding body and an annular conductor. The power transmission assembly is fixedly arranged on the inner wall of the outer shell, the arc magnet is fixedly arranged on the inner wall of the outer shell, two groups of arc magnets are provided, the two groups of arc magnets have opposite poles, the rounding body is arranged in the two groups of arc magnets, the annular conductor is rotatably arranged in the outer shell, one end of the conductor segment is rotatably arranged in the power transmission assembly, and the other end of the conductor segment passes through the rounding body and is fixed on the annular conductor. The conductor segment, the power transmission assembly and the annular conductor form a complete power supply and electricity system. Under the action of the arc magnet with opposite poles, the conductor segment rotates in a directional manner, thereby driving the rounding body to rotate, and the rounding body rotates to round the surface of the resin tube.

[0007] Furthermore, the radius control component includes a hydraulic pump, a vertical control component and a lateral control component. The hydraulic pump is fixed on a fixed bracket, the bottom end of the vertical control component is fixed on the output end of the hydraulic pump, the vertical control component is provided with four groups, the bottom end of the lateral control component is fixed on the vertical control component, and the lateral control component is provided with four groups. The vertical control component and the lateral control component cooperate with each other to adjust the radius of the rounding body to adapt to the rounding of resin tubes of different diameters. The hydraulic pump provides power for the movement of the vertical control component and the lateral control component.

[0008] Furthermore, the wire segment includes a connecting wire bundle, an elastic wire bundle and a flat-segment wire bundle. Two groups of connecting wire bundles are provided. One end of the connecting wire bundle is rotatably arranged in the power transmission component, and one end of the elastic wire bundle is fixedly arranged at the other end of the connecting wire bundle. The elastic wire bundle is hollow in a spring shape, and an electrorheological fluid is arranged in the elastic wire bundle. The two ends of the flat-segment wire bundle are connected to the other ends of the two groups of elastic wire bundles. The connecting wire bundle and the flat-segment wire bundle are made of copper, and the elastic wire bundle is made of phosphor bronze. When the radius of the pressing circle changes, the length of the elastic wire bundle can change accordingly. After the length of the elastic wire bundle changes, the arc conductor is energized. At this time, the elastic wire bundle is energized, and the internal electrorheological fluid is energized. The electrorheological fluid is solid, and the elastic wire bundle is fixed under the action of the solid electrorheological fluid.

[0009] Furthermore, the power transmission component includes an insulating ring, an arc conductor, an arc pushing plate 1, a power supply and a resistance box. The arc conductor is fixed on the outer shell, and there are two groups of arc conductors. There are two groups of insulating rings. The two groups of insulating rings are rotatably arranged at both ends of the arc conductor. The arc pushing plate 1 is fixed on the radius control component, and there are four groups of arc pushing plates. The power supply is fixed on the fixed bracket, and the resistance box is fixed on the fixed bracket. The two groups of arc conductors are electrically connected to the two poles of the power supply, the power supply is electrically connected to the resistance box, and the resistance box is electrically connected to the arc conductor. A group of connecting wire bundles is fixed in the two groups of insulating rings, and the ends of the connecting wire bundles are rotatably arranged on the arc conductor, and the other end of the other group of connecting wire bundles is fixed on the annular conductor. The two groups of insulating rings limit the wire segments to prevent the wire segments from sliding relative to each other. By adjusting the size of the resistance box and the size of the current in the circuit, the rotation speed of the rounding body changes with the change of the current size, thereby achieving the technical effect of rounding different pipe surfaces.

[0010] Furthermore, the rounding body includes a semicircular rounding bottom plate, a semicircular rounding top plate, an insulating heat-insulating layer, a heating layer and a limiting plate. The semicircular rounding top plate is slidably arranged on an arc-shaped pushing plate, and the semicircular rounding bottom plate is fixedly arranged on the semicircular rounding top plate. The semicircular rounding top plate and the semicircular rounding bottom plate form a cavity. The insulating heat-insulating layer and the heating layer are fixedly arranged between the semicircular rounding top plate and the semicircular rounding bottom plate. The insulating heat-insulating layer is made of chloroprene rubber, and the heating layer is located under the insulating heat-insulating layer. The limiting plate is fixedly arranged on the semicircular rounding top plate. Two sets of limiting plates are arranged at each end of the rounding body. The heating layer heats the semicircular rounding bottom plate, thereby heating the surface of the resin tube, which is convenient for rounding the surface of the resin tube. The insulating heat-insulating layer prevents the electric current of the wire segment from being transferred to the resin tube. At the same time, the insulating heat-insulating layer also prevents the heat on the heating layer from being transferred to the wire segment. The limiting plate prevents the rounding body from being displaced.

[0011] Furthermore, the vertical control assembly includes a power plate, a power support rod, a vertical push-pull rod, a fixed block, a support shaft, a connecting plate, a connecting rod, a folding connecting rod, an upper vertical control rod and a lower vertical control rod. The power plate is fixedly arranged at the output end of the hydraulic pump, the middle part of the power support rod is fixedly arranged on the power plate, the vertical push-pull rod is fixedly arranged at both ends of the power support rod, the fixed block is fixedly arranged on the vertical push-pull rod, the support shaft is rotatably arranged on the fixed bracket, the connecting plate is rotatably arranged on the support shaft, the bottom end of the connecting rod is fixedly arranged on the fixed block, the top end of the connecting rod is hingedly arranged on the connecting plate, the connecting rod is located on one side of the support shaft, the bottom end of the folding connecting rod is hingedly arranged on the connecting plate, the folding connecting rod is located on the other side of the support shaft, the top end of the upper vertical control rod is fixedly arranged on the folding connecting rod, and the lower vertical control rod is fixedly arranged in the middle part of the power support rod, pushing the vertical push-pull rod, and driving the connecting rod to move through the fixed block, so that the connecting plate rotates with the support shaft as the center of the circle, and then pulls the folding connecting rod and the upper vertical control rod to move, and finally achieves the purpose of controlling the radius of the pressing circle.

[0012] Furthermore, the transverse control component includes a hinged plate and a transverse control rod. The hinged plate is hinged at the top of the vertical push-pull rod, and the transverse control rod is hinged on the hinged plate. The movement of the vertical push-pull rod drives the movement of the transverse control rod through the hinged plate, thereby cooperating with the vertical control component to achieve the technical effect of controlling the radius of the pressing circle.

[0013] Furthermore, the auxiliary component includes an arc-shaped pushing plate 2 and a circular tube control ring. The arc-shaped pushing plate 2 is provided with four groups. The outer wall of the arc-shaped pushing plate 2 is fixedly arranged on one group of upper vertical control rods, lower vertical control rods and horizontal control rods. The circular tube control ring is slidably arranged on the inner wall of the arc-shaped pushing plate 2. The circular tube control ring is provided with two groups. The diameter of the circular tube control ring is adjusted by moving the arc-shaped pushing plate 2 to adapt to resin tubes of different diameters.

[0014] Furthermore, the fixed bracket includes a bracket body, a fixed guide rail and a support member. The fixed guide rail is fixedly arranged on the bracket body. There are eight groups of fixed guide rails. The transverse control rod is slidably arranged in the fixed guide rail. The support member is fixedly arranged on the bracket body. The support shaft is rotatably arranged on four groups of support members.

[0015] Furthermore, two groups of slits are formed through the outer shell at the limiting plate.

[0016] Furthermore, the arc-shaped pushing plate is fixedly arranged on the upper vertical control rod, the lower vertical control rod and the transverse control rod in the three groups of vertical control components and the transverse control components.

[0017] Further, the heating layer is electrically connected to a power source.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows: (1) A radius control assembly is set up so that the three groups of vertical control assemblies and the three groups of lateral control assemblies cooperate with each other. The output end of the hydraulic pump drives the power plate to move. The power plate drives the vertical push-pull rod to move while driving the lower vertical control rod to move. The vertical push-pull rod drives the fixed block to move. Through the linkage of the connecting rod, the connecting plate and the folding connecting rod, the upper vertical control rod and the lower vertical control rod are driven to move relative to each other. The upper vertical control rod drives the upper arc-shaped push plate to move. The lower vertical control rod drives the lower arc-shaped push plate to move. The vertical push-pull plate moves and drives the hinged plate to move. The hinged plate drives the lateral control rod to move. The lateral control rod drives the front and rear two groups of arc-shaped push plates to move. When the four groups of arc-shaped push plates are retracted, The semicircular rounding bottom plate and the semicircular rounding top plate shrink, and the elastic wire bundle shrinks. When the four sets of arc-shaped pushing plates expand, the semicircular rounding bottom plate and the semicircular rounding top plate expand, and the elastic wire bundle stretches, so as to achieve the technical effect of adjusting the diameter of the rounding body. Compared with the existing technology of using multiple sets of rollers to round the surface of the tube body, the technical effect of adjusting the radius of the rounding body at one time is achieved only through its own ingenious structural design without using electronic components or manual adjustment, which reduces the workload of the staff and increases the accuracy and flexibility of adjusting the radius of the rounding body, thereby improving the quality of the rounding of the resin tube surface and improving the practicality of the resin tube surface rounding extruder; (2) Using the principle of electromagnetism, a circular pressing component is set up. A power supply circuit is formed between the power supply and the arc conductor, the wire segment, the ring conductor and the resistance box. The wire segment is energized, and the electrorheological fluid in the elastic wire bundle is energized. The elastic wire bundle maintains a fixed shape. Under the action of two groups of arc magnets with opposite electrodes outside the wire segment, it can be seen from the left-hand rule that when the direction of the current is constant, the direction of the magnetic force on the wire segment is constant. Because the electrodes of the two groups of arc conductors are opposite, the directions of the forces on the wire segments connected to the two groups of arc conductors are opposite. Under the action of opposite forces, the wire segment performs circular motion. When the wire segment moves to the edge of one group of arc conductors, under the action of inertia, the wire segment will pass through the edge of the group of arc conductors and move to the other group of arc conductors. At this time, the direction of the current changes, and the direction of the force changes. This process is repeated, causing the wire segment to perform circular motion. The circular motion is repeated over and over again. Since the flat wire bundle is located in the semicircular dome pressing top plate, the rotation of the wire segment drives the dome pressing body to rotate, the heating layer is heated, and the heat is transferred to the resin tube through the semicircular dome pressing bottom plate to soften the surface of the resin tube. According to the different materials or thicknesses of the resin tube, the size of the resistor box is adjusted to adjust the size of the current in the circuit, and then the force of the wire segment is adjusted, and finally the purpose of adjusting the rotation speed of the dome pressing body is achieved, avoiding the risk of local stress concentration on the tube body causing deformation and damage to the tube due to the pressure being concentrated in the contact area between the roller and the tube body. At the same time, by adjusting the rotation speed of the dome pressing body, the technical effect of surface dome pressing of tubes of different materials and thicknesses is also achieved, which not only improves the quality of the surface dome pressing of the resin tube body, but also increases the applicability of the tube surface dome pressing extruder and reduces energy waste. (3) The rounding component and the auxiliary component are integrated, and the radius control component and the auxiliary component are set. One set of vertical control components and lateral control components are connected with the other three sets of vertical control components and lateral control components through a power plate. The vertical control component and the lateral control component adjust the radius of the rounding component and the radius of the auxiliary component at the same time, so that the radius of the auxiliary component adapts to the size of the resin tube required for rounding the surface, thereby avoiding the problem of the resin tube being offset when the rounding component rounds the surface of the resin tube, thereby affecting the quality of the rounding of the resin tube surface, and also avoiding the problem of the need to replace or adjust appropriate components according to resin tubes of different diameters when the auxiliary components are set separately, thereby increasing the flexibility of the resin tube surface rounding extruder and reducing the workload of the staff; (4) By using the principle of electromagnetism and directional magnetic field, the rounding body and the arc magnet can achieve the purpose of rounding the surface of the resin tube without contact. Compared with the existing tube surface rounding extruder in which the rods are connected to each other, the noise released by the rounding extruder during the rounding process of the resin tube surface is reduced, creating a more comfortable working environment for the staff.

[0036] like Figure 1 As shown, the heating layer is electrically connected to a power source.

[0037] When in use, the diameters of the pressing component 3 and the auxiliary component 5 are adjusted according to the diameter of the resin tube, and the hydraulic pump 11 is turned on. The output end of the hydraulic pump 11 pushes the power plate 25 to move. The power plate 25 pushes the vertical push-pull rod 27 to move while pushing the lower vertical control rod 34 to move. The vertical push-pull rod 27 drives the fixed block 28 to move. The fixed block 28 drives the connecting rod 31 to move. The connecting rod 31 drives the connecting plate 30 to move in an arc with the support shaft 29 as the center of the circle. The connecting plate 30 drives the folding connecting rod 32 to move. At this time, the folding connecting rod 32 and the connecting rod 31 move toward each other, and the folding connecting rod 32 drives the upper vertical control rod 33 to move. Finally, the lower vertical control rod 34 and the upper vertical control rod 33 move toward each other, that is, when the vertical push-pull rod 27 moves upward, the upper vertical control rod 33 moves. The upper vertical control rod 33 moves downward, and the lower vertical control rod 34 moves upward. When the vertical push-pull rod 27 moves downward, the upper vertical control rod 33 moves upward, and the lower vertical control rod 34 moves downward. The upper vertical control rod 33 drives the upper arc-shaped push plate 19 and the upper arc-shaped push plate 2 37 to move, and the lower vertical control rod 34 drives the lower arc-shaped push plate 19 and the lower arc-shaped push plate 2 37 to move. The vertical push-pull rod 27 moves to drive the hinge plate 35 to move, and the hinge plate 35 drives the transverse control rod 36 to move. Because the bottom end of the hinge plate 35 is hinged on the vertical push-pull rod 27, and the transverse control rod 36 is hinged on the top of the hinge plate 35, when the vertical push-pull rod 27 moves upward, the hinge plate 35 drives the transverse control rod 36 to move inward. When moving downward, the hinged plate 35 drives the lateral control rod 36 to move outward, and the lateral control rod 36 pushes the front and rear two groups of arc-shaped push plates 19 and the arc-shaped push plates 2 37 to move, so as to achieve the effect of contraction or expansion of the four groups of arc-shaped push plates 19 and the four groups of arc-shaped push plates 2 37. When the four groups of arc-shaped push plates 19 contract, the semicircular dome-pressing bottom plate 20 and the semicircular dome-pressing top plate 21 contract, the round tube control ring 38 contracts, and the elastic wire bundle 15 contracts. When the four groups of arc-shaped push plates 19 and the four groups of arc-shaped push plates 2 37 expand, the semicircular dome-pressing bottom plate 20, the semicircular dome-pressing top plate 21 and the round tube control ring 38 expand accordingly, and the elastic wire bundle 15 stretches, thereby finally achieving the effect of adjusting the diameter size of the dome-pressing body 9 and the auxiliary component 5. Turn on the power 39, and the heating The layer 23 is heated, and the heating layer 23 transfers heat to the semicircular pressing bottom plate 20. The heat softens the surface of the resin tube to facilitate the pressing of the surface. A power supply circuit is formed between the power supply 39 and the arc conductor 18, the wire segment 6, the annular conductor 10 and the resistor box 40. The wire segment 6 is energized, and the electrorheological fluid in the elastic wire bundle 15 is energized. The electrorheological fluid is solid, so that the shape of the elastic wire bundle 15 remains unchanged. Because there is an arc magnet 8 with opposite electrodes outside the energized wire segment 6, the wire segment 6 is affected by the magnetic force. Using the left-hand rule, it can be seen that when the direction of the current is constant, the direction of the magnetic force on the wire segment 6 is constant. Because the electrodes of the two groups of arc conductors 18 are opposite, the wire segments 6 connected to the two groups of arc conductors 18 are subjected to opposite forces.The wire segment 6 performs circular motion under the action of force. When the wire segment 6 moves to the edge of a group of arc-shaped conductors 18, under the action of inertia, the wire segment 6 will move through the edge of the group of arc-shaped conductors 18 to another group of arc-shaped conductors 18. At this time, the direction of the current changes, and the direction of the force changes. This is repeated, so that the wire segment 6 performs a circular motion over and over again. Because the flat wire bundle 16 is located in the semicircular dome pressing top plate 21, the rotation of the wire segment 6 drives the dome pressing body 9 to rotate. According to the different materials of the resin tube or the thickness of the resin tube, the size of the current in the circuit is adjusted by adjusting the size of the resistor box 40, thereby adjusting the size of the force on the wire segment 6, and then adjusting the rotation speed of the dome pressing body 9. The resin tube is connected to the auxiliary component 5. After the resin tube performs uninterrupted surface dome pressing work in the dome pressing body 9, it is pulled out of the tube surface dome pressing extruder by other traction devices.
