Description

Technical Field

[0001] This invention relates to the technical field of feed line processing, and in particular to an extrusion press for connecting feed lines to iron towers. Background Technology

[0002] In power transmission line engineering, the iron tower (or power pole) is the core supporting structure of the overhead transmission line. When the overhead transmission conductor passes through the iron tower, it cannot be directly crossed. Jumper wires (i.e., diverter wires) are needed to achieve electrical connection and reversal. As a key conductive component connecting the conductor and the electrical equipment on the iron tower side, the reliability of the connection directly affects the operational safety of the transmission line and the stability of current transmission. The diverter plate is the core hardware component that realizes the electrical connection and mechanical fixation between the diverter wire and the tension clamp or diverter pipe. In the connection process between the diverter wire and the diverter plate, one end of the diverter wire is usually inserted into the pre-set circular hole of the diverter plate. Then, a special extrusion machine is used to extrude and form the diverter plate, so that the diverter plate is transformed from the initial cylindrical shape into a polygonal cross-section shape. The plastic deformation of the base material of the diverter plate forms a tight grip on the diverter wire placed inside, thereby completing the connection between the diverter wire and the diverter plate.

[0003] Currently used extrusion presses mainly apply extrusion pressure to the guide plate through corresponding grooves on two internal extrusion plates. When the two extrusion plates move towards each other and gradually approach to extrude the guide plate, the matrix material of the guide plate undergoes plastic flow and volume migration under compressive stress. During this process, some material migrates to the gap area between the two extrusion plates under the extrusion pressure, causing burrs to be generated on the surface of the extruded guide plate. These burrs need to be removed by operators using pliers, files, or other special finishing tools, which significantly increases the process time and labor costs. Therefore, due to the limitations of its structural design, traditional extrusion presses cannot obtain a guide plate with a complete surface and no excess burrs in a single extrusion forming process. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an extrusion press for connecting tower guide wires, the specific technical solution of which is as follows: An extrusion press for connecting a tower diversion line according to the present invention includes an outer frame and an extrusion body disposed within the outer frame, wherein the extrusion body extrudes and deforms the diversion plate; The extrusion body includes a support ring and a plurality of guide bodies disposed within the support ring along the circumferential direction of the support ring. Each guide body is slidably provided with an extrusion plate. One end of the extrusion plate slides in contact with the side wall of the adjacent extrusion plate, so that the plurality of extrusion plates form a closed polygon. As the extrusion plate moves on the guide body, the internal space of the polygon increases or decreases.

[0005] Furthermore, the extension line of the movement trajectory of the extrusion plate on the guide intersects with and is perpendicular to the axis of the polygon.

[0006] Furthermore, the extrusion plate has a pressing ridge on the surface facing the polygon, the pressing ridge has a T-shaped cross-section, and the end of the extrusion plate has a groove that matches the shape of the pressing ridge.

[0007] Furthermore, the number of extrusion bodies is set to at least two, and each of the extrusion bodies is arranged along the axis of the polygon.

[0008] Furthermore, the polygons formed by several extrusion plates within two adjacent extrusion bodies are staggered in the circumferential direction of the outer frame.

[0009] Furthermore, an arc-shaped pressure edge is provided on the side wall of the extrusion plate in the extrusion body corresponding to the end of the diversion plate to extrude and gather the end of the diversion plate.

[0010] Furthermore, the extrusion body is movable within the outer frame via an adjusting cylinder to adjust the distance between two adjacent extrusion bodies, and can extrude a knot on the guide plate between two adjacent extrusion bodies.

[0011] Furthermore, a drive ring is provided between two adjacent extrusion bodies, and the drive ring is rotatably disposed within the outer frame via a guide seat. The drive ring has a plurality of oblique holes, which are distributed along the circumferential direction of the drive ring, and the oblique holes are offset from the axis of the outer frame. A push pin is provided on the extrusion plate. The push pin is used in combination with the inclined hole so that the extrusion plate moves on the guide body during the rotation of the drive ring. A drive cylinder is provided on the outer frame, and a movable plate is provided at the output end of the drive cylinder. The movable plate is connected to each of the drive rings in a transmission manner.

[0012] The beneficial effects of this invention are as follows: By directly extruding the diverting plate with a closed polygon composed of several extrusion plates, the shape of the diverting plate can be directly transformed from a cylinder to a polygon. Since some material on the diverting plate cannot be transferred between two adjacent extrusion plates, no burrs will be generated on the outer wall of the formed diverting plate. This achieves one-time forming of the diverting plate, avoiding the manpower and time wasted in subsequent burr trimming. It can not only simplify the operation and improve work efficiency, but also improve the flatness of the surface of the formed diverting plate. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 8 As shown, an extrusion press for connecting a tower diversion line according to the present invention includes an outer frame 1 and an extrusion body 2 disposed within the outer frame 1, wherein the extrusion body 2 extrudes and deforms the diversion plate 15. The extrusion body 2 includes a support ring 3 and a plurality of guide bodies 4 disposed within the support ring 3 along the circumferential direction of the support ring 3. Each guide body 4 is slidably provided with an extrusion plate 5. One end of the extrusion plate 5 is in sliding contact with the side wall of the adjacent extrusion plate 5, so that the plurality of extrusion plates 5 form a closed polygon. As the extrusion plate 5 moves on the guide body 4, the internal space of the polygon increases or decreases.

[0019] In this invention, the outer frame 1 provides support for the extrusion body 2, and the support ring 3 inside the extrusion body 2 provides support and movement space for a plurality of guide bodies 4 and a plurality of extrusion plates 5; the plurality of extrusion plates 5 are distributed in a polygonal shape, and the extrusion plates 5 are located on one side of the polygon. One end of the extrusion plate 5 slides in contact with the side wall of the adjacent extrusion plate 5, and the other end of the extrusion plate 5 is located on the outside of the polygon, thereby forming a closed polygonal structure with the plurality of extrusion plates 5. Since the adjacent two extrusion plates 5 slide in contact with each other, the gap between them is small, and some material on the diversion plate 15 cannot enter the gap. The plurality of extrusion plates 5 realize a full-wrap extrusion mode on the diversion plate 15 in the circumferential direction of the diversion plate 15.

[0020] In use, one end of the drain line 16 is inserted into the circular hole at the end of the drain plate 15 to a specified depth, so that the extrusion plate 5 moves on the guide body 4 in a direction away from the axis of the outer frame 1. The internal space of the polygon formed by the extrusion plates 5 increases, making it easier to pass the drain plate 15 through the polygon. The area to be extruded on the drain plate 15 is located inside the polygon. The extrusion plates 5 move on the corresponding guide body 4 in a direction away from the axis of the outer frame 1, so that the internal space of the polygon formed by the extrusion plates 5 decreases. The surface of the extrusion plate 5 facing the axis of the outer frame 1 contacts the outer wall of the drain plate 15 and extrudes the drain plate 15. Due to the characteristics of the closed polygon formed by the multiple extrusion plates 5, some material on the drain plate 15 cannot be transferred to the gap between two adjacent extrusion plates 5. The shape of the drain plate 15 gradually changes into a regular polygon, and no burrs are generated on the outer wall of the drain plate 15.

[0021] By directly extruding the diversion plate 15 with a closed polygon composed of several extrusion plates 5, the shape of the diversion plate 15 can be directly transformed from a cylinder to a polygon. Since some material on the diversion plate 15 cannot be transferred between two adjacent extrusion plates 5, no burrs will be generated on the outer wall of the formed diversion plate 15. This achieves one-time forming of the diversion plate 15, avoiding the manpower and time wasted in subsequent burr trimming. This simplifies the operation, improves work efficiency, and enhances the flatness of the formed diversion plate 15 surface.

[0022] Furthermore, the extension line of the movement trajectory of the extrusion plate 5 on the guide body 4 intersects with and is perpendicular to the axis of the polygon.

[0023] When the extension line of the movement trajectory of the extrusion plate 5 on the guide body 4 deviates from the axis of the polygon, the extrusion plate 5 will be displaced relative to the polygon in the circumferential direction of the outer frame 1 during the movement towards the axis of the polygon. That is, the point on the extrusion plate 5 where the perpendicular line between the face of the extrusion plate 5 facing the axis of the outer frame 1 and the axis of the outer frame 1 will be offset as the extrusion plate 5 moves. Thus, when the extrusion plate 5 extrudes the outer wall of the diversion plate 15, this offset will cause the extrusion plate 5 to push and transfer part of the material on the diversion plate 15 along the circumferential direction of the diversion plate 15. The simultaneous extrusion of the diversion plate 15 by multiple extrusion plates 5 will cause the diversion plate 15 to rotate in its circumferential direction, which can easily cause tearing damage to the material on the diversion plate 15.

[0024] By limiting the movement trajectory of the extrusion plate 5 as described above, the extrusion plate 5 can vertically extrude the diversion plate 15, thus preventing the extrusion plate 5 from shifting in the circumferential direction of the diversion plate 15.

[0025] Furthermore, the extrusion plate 5 has a pressing ridge 6 on the polygonal surface, the pressing ridge 6 has a T-shaped cross-section, and the end of the extrusion plate 5 has a groove that matches the shape of the pressing ridge 6.

[0026] By utilizing the pressure ridges 6 provided on each extrusion plate 5, when the extrusion plate 5 extrudes the drainage plate 15, the pressure ridges 6 extrude indentations on the outer wall of the drainage plate 15. The area on the inner wall of the drainage plate 15 corresponding to the indentations will exert a greater extrusion effect on the local drainage line 16, thereby achieving mechanical engagement of the drainage plate 15 and improving the connection strength between the drainage plate 15 and the drainage line 16.

[0027] By setting the shape of the pressure rib 6 and the corresponding groove on the extrusion plate 5, two adjacent extrusion plates 5 can be slidably connected to each other through the pressure rib 6 and the groove, thereby improving the tightness between the two adjacent extrusion plates 5.

[0028] Furthermore, the number of extrusion bodies 2 is set to at least two, and each extrusion body 2 is arranged along the polygonal axis.

[0029] The characteristic of using multiple extrusion bodies 2 to extrude different areas on the diversion plate 15 can achieve a multi-segment interval pressing effect, increase the effective area, facilitate the formation of multiple stress concentration areas on the diversion plate 15, and improve the connection effect between the diversion plate 15 and the diversion line 16.

[0030] In actual use, multiple extrusion bodies 2 can apply pressure one by one from the end of the diversion plate 15 toward the end of the diversion line 16 toward the end of the diversion plate 15 away from the diversion line 16, to prevent the diversion line 16 inside the diversion plate 15 from moving outward.

[0031] Furthermore, the polygons formed by several extrusion plates 5 within two adjacent extrusion bodies 2 are staggered in the circumferential direction of the outer frame 1.

[0032] Each extrusion plate 5 within the extrusion body 2 can form a polygon. These polygons are arranged linearly, and their angles along the circumference of the outer frame 1 are staggered. That is, if the top edge of the first polygon is horizontal, then the top edge of the second polygon can be tilted. In this way, the angles of the polygons of the multiple extrusion zones formed on the outer wall of the guide plate 15 are also staggered. Correspondingly, the shapes of the guide lines 16 in different extrusion zones inside the guide plate 15 are staggered. Using this characteristic, a locking effect on the guide lines 16 can be achieved, preventing the guide lines 16 corresponding to different extrusion zones from moving along the axial direction of the guide plate 15.

[0033] Furthermore, an arc-shaped pressing edge 7 is provided on the side wall of the extrusion plate 5 inside the extrusion body 2 corresponding to the end of the diversion plate 15 to extrude and gather the end of the diversion plate 15.

[0034] The arc-shaped pressing edge 7 is located on the side wall of the extrusion plate 5 of one of the extrusion bodies 2 near the guide line 16. That is, the arc-shaped pressing edge 7 on the extrusion body 2 can correspond to the end of the guide plate 15. When the extrusion plates 5 approach each other, the arc-shaped pressing edge 7 simultaneously approaches each other and presses the end of the guide plate 15, thereby realizing the end-closing process of the guide plate 15, which facilitates the radial limitation of the guide line 16.

[0035] Furthermore, the extrusion body 2 is movable within the outer frame 1 by adjusting the oil cylinder 8 to adjust the distance between two adjacent extrusion bodies 2, and can extrude a knot on the guide plate 15 between two adjacent extrusion bodies 2.

[0036] The adjusting cylinder 8 can provide power for adjusting the position of the extrusion body 2 within the outer frame 1, thereby adjusting the distance between the areas where adjacent extrusion bodies 2 extrude the guide plate 15, and facilitating the application of guide plates 15 of different lengths.

[0037] When two adjacent extrusion bodies 2 extrude the outer wall of the guide plate 15 into a polygon, the adjusting cylinder 8 can push the two adjacent extrusion bodies 2 closer to each other. At this time, the two adjacent extrusion bodies 2 extrude the portion of the guide plate 15 between them. The portion of the guide line 16 on the inner side of this portion of the guide plate 15 is also extruded along the axial direction of the guide plate 15. As a result, a knot with a relatively large volume relative to the outer shape of the guide plate 15 is formed between two adjacent extrusion areas on the guide plate 15. This knot can prevent the guide line 16 from coming off.

[0038] Furthermore, a drive ring 9 is provided between two adjacent extrusion bodies 2, and the drive ring 9 is rotatably disposed within the outer frame 1 via a guide seat 10. Several oblique holes 11 are provided on the drive ring 9, and the oblique holes 11 are distributed along the circumferential direction of the drive ring 9, and the oblique holes 11 are offset from the axis of the outer frame 1. A pusher 12 is provided on the extrusion plate 5. The pusher 12 is used in combination with the inclined hole 11 to make the extrusion plate 5 move on the guide body 4 during the rotation of the drive ring 9. A drive cylinder 13 is provided on the outer frame 1, and a movable plate 14 is provided at the output end of the drive cylinder 13. The movable plate 14 is connected to each drive ring 9 in a transmission connection.

[0039] The drive ring 9 is located between two adjacent extrusion bodies 2. Since the extrusion plates 5 in the two adjacent extrusion bodies 2 are offset in the circumferential direction of the outer frame 1, the push pins 12 on the extrusion plates 5 in the two adjacent extrusion bodies 2 can correspond to different oblique holes 11 on the drive ring 9. That is, several oblique holes 11 on the drive ring 9 can simultaneously cooperate with several extrusion plates 5 on the two adjacent extrusion bodies 2.

[0040] Since the oblique hole 11 is offset relative to the axis of the outer frame 1, the oblique hole 11 and the movement trajectory of the extrusion plate 5 on the guide body 4 are at a certain angle. When the drive ring 9 rotates, the oblique hole 11 can push the extrusion plate 5 to move through the push pin 12. The extrusion plate 5 slides on the guide body 4, thereby providing moving power for several extrusion plates 5.

[0041] The outer circumferential wall of the drive ring 9 is in transmission contact with the side wall of the movable plate 14. When the drive cylinder 13 drives the movable plate 14 to move, the movable plate 14 can push the drive ring 9 to slide within the outer frame 1. The guide seat 10 provides support for the drive ring 9, thereby causing the extrusion plates 5 on several extrusion bodies 2 to move synchronously. Of course, the side wall of the movable plate 14 can simultaneously be in transmission contact with the outer walls of multiple drive rings 9.

[0042] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
