Description

Technical Field

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

[0002] A resin pipe refers to a high-pressure hose formed by using a plastic extruded hose as the inner core and reinforcing it with high-strength industrial fibers or steel wires through knitting or winding. The tube body generally has a three-layer structure of an inner hose layer, a skeleton reinforcement layer, and an outer rubber layer. Resin pipes have the advantages of high pressure resistance, light weight, high temperature resistance, good flame retardancy, and good elasticity, and are widely used in industries such as petroleum, chemical engineering, construction machinery manufacturing, coal mines, shipbuilding, aviation, automobiles, and medical devices. To ensure the quality of resin pipe production, it is usually necessary to round the surface of the resin pipe.

[0003] The prior art discloses a tube body surface rounding extruder for resin pipe production, with the authorization publication number CN213006530U. This application effectively solves the problems of time-consuming and laborious operation, difficulty in getting started, and low production efficiency of the rounding extruder in the prior art by setting three groups of sliding grooves and three groups of rounding rollers. However, the rounding extruder in this application consists of multiple groups of rollers, and it is difficult to adjust the precision between the multiple groups of rollers. It is relatively complex for production personnel to adjust the equipment. Moreover, when multiple groups of rollers work, the noise is large. Also, during the tube body rounding process of the rounding extruder in this application, the pressure 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 tube deformation and damage. In addition, the rollers in this application cannot adjust the rotation speed according to different materials and thicknesses of the tubes, reducing the applicability of the rounding extruder. Finally, the auxiliary equipment in the prior art rounding extruder is set separately. For rounding the surface of resin pipes with different diameters, it is necessary to separately replace or adjust appropriate devices, reducing the flexibility of the rounding extruder. Summary of the Invention

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

[0005] The technical solution adopted by the present invention is as follows: A tube body surface rounding and extruding machine 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 inside the outer shell. The radius control component is fixedly arranged on the fixed bracket. The auxiliary component is arranged inside the outer shell and is located at the inlet of the rounding and extruding machine. 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 is adjusted to adjust the inner diameter size of the rounding component, so as to adapt to the surface rounding work of resin tubes with different diameters.

[0006] Further, the rounding component includes a wire segment, a power supply component, an arc magnet, a rounding body, and a ring conductor. The power supply component 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. There are two groups of arc magnets, and the two groups of arc magnets are of opposite magnetic poles. The rounding body is arranged inside the two groups of arc magnets. The ring conductor is rotatably arranged inside the outer shell. One end of the wire segment is rotatably arranged inside the power supply component, and the other end of the wire segment passes through the rounding body and is fixedly arranged on the ring conductor. The wire segment, the power supply component, and the ring conductor form a complete power supply and power consumption system. Under the action of the arc magnet with opposite magnetic poles, the wire segment rotates directionally, thereby driving the rounding body to rotate, and the rotation of the rounding body rounds the surface of the resin tube.

[0007] Further, the radius control component includes a hydraulic pump, a vertical control component, and a horizontal control component. The hydraulic pump is fixedly arranged on the fixed bracket. The bottom end of the vertical control component is fixedly arranged on the output end of the hydraulic pump. There are four groups of vertical control components. The bottom end of the horizontal control component is fixedly arranged on the vertical control component. There are four groups of horizontal control components. The vertical control component and the horizontal control component cooperate with each other to adjust the radius size of the rounding body to adapt to the rounding of resin tubes with different diameters. The hydraulic pump provides power for the movement of the vertical control component and the horizontal control component.

[0008] Further, the wire segment includes a connecting wire bundle, an elastic wire bundle, and a flat wire bundle. There are two groups of connecting wire bundles. One end of the connecting wire bundle is rotatably arranged inside the power supply component. One end of the elastic wire bundle is fixedly arranged at the other end of the connecting wire bundle. The elastic wire bundle is in the shape of a spring hollow. There is an electrorheological fluid inside the elastic wire bundle. The two ends of the flat wire bundle are connected to the other ends of the two groups of elastic wire bundles. The connecting wire bundle and the flat wire bundle are made of copper, and the elastic wire bundle is made of phosphor bronze. When the radius of the rounding body changes, the length of the elastic wire bundle can change accordingly. After the length change of the elastic wire bundle is completed, the arc conductor is electrified. At this time, the elastic wire bundle is electrified, and the internal electrorheological fluid is electrified, and the electrorheological fluid becomes solid. The elastic wire bundle assumes a fixed shape under the action of the solid electrorheological fluid.

[0009] Furthermore, the power transmission component includes an insulating ring, an arc-shaped conductor, a first arc-shaped pushing plate, a power source, and a resistance box. The arc-shaped conductor is fixedly arranged on the outer housing, and there are two sets of arc-shaped conductors. There are two sets of insulating rings, and the two sets of insulating rings are rotatably arranged at both ends of the arc-shaped conductor. The first arc-shaped pushing plate is fixedly arranged on the radius control component, and there are four sets of the first arc-shaped pushing plates. The power source is fixedly arranged on the fixed bracket, and the resistance box is fixedly arranged on the fixed bracket. The two sets of arc-shaped conductors are electrically connected to the two poles of the power source. The power source is electrically connected to the resistance box, and the resistance box is electrically connected to the arc-shaped conductor. A set of connecting wire bundles is fixedly arranged inside the two sets of insulating rings, and the end of this set of connecting wire bundles is rotatably arranged on the arc-shaped conductor. The other end of the other set of connecting wire bundles is fixedly arranged on the annular conductor. The two sets of insulating rings play a role in limiting the wire segment to prevent relative sliding of the wire segment. By adjusting the size of the resistance box, the magnitude of the current in the circuit is adjusted, and the rotation speed of the round pressing body changes with the magnitude of the current, thereby achieving the technical effect of pressing the surface of different pipes into a round shape.

[0010] Furthermore, the round pressing body includes a semi-circular round pressing bottom plate, a semi-circular round pressing top plate, an insulating and heat-insulating layer, a heating layer, and a limiting plate. The semi-circular round pressing top plate is slidably arranged on the first arc-shaped pushing plate, and the semi-circular round pressing bottom plate is fixedly arranged on the semi-circular round pressing top plate. The semi-circular round pressing top plate and the semi-circular round pressing bottom plate form a cavity. The insulating and heat-insulating layer and the heating layer are fixedly arranged between the semi-circular round pressing top plate and the semi-circular round pressing bottom plate. The material of the insulating and heat-insulating layer is chloroprene rubber. The heating layer is located below the insulating and heat-insulating layer. The limiting plate is fixedly arranged on the semi-circular round pressing top plate, and two sets of limiting plates are arranged at both ends of the round pressing body. The heating layer heats the semi-circular round pressing bottom plate, thereby heating the surface of the resin pipe to facilitate pressing the surface of the resin pipe into a round shape. The insulating and heat-insulating layer prevents the electrical charge of the wire segment from being transmitted to the resin pipe. At the same time, the insulating and heat-insulating layer also prevents the heat on the heating layer from being transmitted to the wire segment. The limiting plate prevents the round pressing body from displacing.

[0011] Furthermore, the vertical control component 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 folded 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 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, and the top end of the connecting rod is hinged on the connecting plate. The connecting rod is located on one side of the support shaft. The bottom end of the folded connecting rod is hinged on the connecting plate, and the folded 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 folded connecting rod. The lower vertical control rod is fixedly arranged in the middle of the power support rod. By pushing the vertical push-pull rod, the connecting rod is driven to move through the fixed block, so that the connecting plate rotates around the support shaft, and then the folded connecting rod and the upper vertical control rod are pulled to move, ultimately achieving the purpose of controlling the radius size of the round pressing body.

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

[0013] Furthermore, the auxiliary component includes four groups of arc-shaped push plates II and two circular tube control rings. The outer walls of the arc-shaped push plates II are fixedly arranged on one group of the upper vertical control rod, the lower vertical control rod, and the lateral control rod. The circular tube control rings are slidably arranged on the inner walls of the arc-shaped push plates II. By moving the arc-shaped push plates II, the diameters of the circular tube control rings are adjusted to adapt to resin tubes of different diameters.

[0014] Furthermore, the fixed bracket includes a bracket main body, fixed guide rails, and supports. The fixed guide rails are fixedly arranged on the bracket main body, and there are eight groups of fixed guide rails. The lateral control rod is slidably arranged in the fixed guide rails. The supports are fixedly arranged on the bracket main body, and the support shafts are rotatably arranged on four groups of supports.

[0015] Furthermore, two sets of gaps are penetrated and opened on the outer shell at the limiting plate.

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

[0017] Furthermore, the heating layer is electrically connected to the power supply.

[0018] The beneficial effects achieved by the present invention with the above structure are as follows:

[0019] (1) Set up a radius control component so that the three sets of vertical control components and the three sets of horizontal control components cooperate with each other. The output end of the hydraulic pump pushes the power plate to move. While the power plate pushes the vertical push rod to move, it also pushes the lower vertical control rod to move. The vertical push rod drives the fixed block to move. Through the linkage of the connecting rod, the connecting plate and the folded connecting rod, it drives the upper vertical control rod and the lower vertical control rod to move relative to each other. The upper vertical control rod drives the upper arc-shaped push plate one to move, and the lower vertical control rod drives the lower arc-shaped push plate one to move. The vertical push-pull plate moves to drive the hinge plate to move, and the hinge plate drives the horizontal control rod to move. The horizontal control rod pushes the front and rear two sets of arc-shaped push plates one to move. When the four sets of arc-shaped push plates one contract, the semi-circular pressing round bottom plate and the semi-circular pressing round top plate contract, and the elastic wire bundle contracts. When the four sets of arc-shaped push plates one expand, the semi-circular pressing round bottom plate and the semi-circular pressing round top plate expand, and the elastic wire bundle elongates, achieving the technical effect of adjusting the diameter of the pressing round body. Compared with the existing technology of using multiple sets of rollers to press the surface of the pipe into a round shape, without using electronic components or manual individual adjustment, only through its ingenious structural design, the technical effect of a one-time overall adjustment of the radius of the pressing round body is achieved, reducing the workload of the staff while also increasing the accuracy and flexibility of the adjustment of the radius of the pressing round body, thereby improving the quality of the surface pressing of the resin pipe and enhancing the practicality of the resin pipe surface pressing extruder;

[0020] (2) By using the principle of electromagnetic induction, a circular pressing component is set up. A power supply forms a power supply and power consumption circuit with an arc conductor, a wire segment, a circular conductor, and a resistance box. When the wire segment is energized, the current-carrying fluid in the elastic wire bundle is energized, and the elastic wire bundle maintains a fixed shape. Under the action of two groups of arc-shaped magnets with opposite electrodes outside the wire segment, according to the left-hand rule, when the current direction is certain, the magnetic force direction on the wire segment is certain. Since the electrodes of the two groups of arc conductors are opposite, the force directions on the wire segments connected to the two groups of arc conductors are opposite. Under the action of the opposite forces, the wire segment makes a circular motion. When the wire segment moves to the edge of a group of arc conductors, due to inertia, the wire segment will move through the edge of this group of arc conductors into the other group of arc conductors. At this time, the current direction changes and the force direction changes. This process repeats, making the wire segment perform a circular motion in a cycle. Since the flat wire bundle is located inside the semi-circular circular pressing top plate, the rotation of the wire segment drives the circular pressing body to rotate, and the heating layer heats up. The heat is transferred to the resin tube through the semi-circular circular pressing bottom plate, softening the surface of the resin tube. According to the type or thickness of the resin tube, the size of the resistance box is adjusted to adjust the current size in the circuit, and then the force on the wire segment is adjusted, ultimately achieving the purpose of adjusting the rotation speed of the circular pressing body. This avoids the risk of pressure concentrating on the contact area between the roller and the tube body, resulting in local stress concentration and deformation and damage of the tube body. At the same time, by adjusting the rotation speed of the circular pressing body, the technical effect of surface circular pressing of resin tubes with different materials and thicknesses is also achieved. This not only improves the quality of surface circular pressing of the resin tube body but also increases the applicability of the tube body surface circular pressing extruder and reduces energy waste;

[0021] (3) The circular pressing component and the auxiliary component are integrated, and a radius control component and an auxiliary component are set up. One group of vertical control components and horizontal control components are connected to the other three groups of vertical control components and horizontal control components through a power plate. When the vertical control components and horizontal control components adjust the radius of the circular pressing component, they also adjust the radius of the auxiliary component, making the radius of the auxiliary component adapt to the size of the resin tube that needs surface circular pressing. This avoids the problem of resin tube deviation during the surface circular pressing of the resin tube by the circular pressing component, which affects the quality of surface circular pressing of the resin tube. At the same time, it also avoids the problem that when the auxiliary component is set separately, it is necessary to separately replace or adjust appropriate devices according to resin tubes of different pipe diameters, increasing the flexibility of the resin tube surface circular pressing extruder and reducing the workload of the staff;

[0022] (4) By using the principle of electromagnetic induction in cooperation with a directional magnetic field, the circular pressing body and the arc-shaped magnet achieve the purpose of surface circular pressing of the resin tube without contact. Compared with the existing tube body surface circular pressing extruder with various rods connected to each other, the noise emission during the surface circular pressing of the resin tube by the circular pressing extruder is reduced, creating a relatively comfortable working environment for the staff.

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 makes a 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 this group of arc-shaped conductors 18 to another group of arc-shaped conductors 18. At this time, the current direction changes and the force-receiving direction changes. This process repeats, causing the wire segment 6 to make a circular motion that goes round and round. Since the flat wire bundle 16 is located within the semi-circular pressing circular top plate 21, the rotation of the wire segment 6 drives the rotation of the pressing circular body 9. Depending on the material or thickness of the resin tube, the magnitude of the current in the circuit is adjusted by adjusting the size of the resistance box 40, thereby adjusting the force received by the wire segment 6 and further adjusting the rotation speed of the pressing circular body 9. The resin tube is connected to the auxiliary component 5. After the surface of the resin tube is continuously pressed into a circular shape within the pressing circular body 9, the tube body is pulled out of the surface pressing circular extruder by other traction devices.
