A high-voltage insulator production press

Abstract

This utility model relates to the field of insulator production technology, and provides a pressing machine for high-voltage insulator production, including a worktable. The pressing machine also includes two sliding grooves located on both sides of the top of the worktable. In this utility model, by using a bidirectional lead screw and a limiting rod, the spacing between the slider, support plate, and fixing rod can be flexibly adjusted. This allows it to adapt to high-voltage insulator pressing molds of different diameters and heights without replacing the entire support structure, reducing equipment investment costs. It is suitable for small-batch, multi-variety insulator production scenarios. Simultaneously, the guiding effect of the limiting rod on the slider prevents the support structure from shifting, ensuring that the pressing mold is always centered during the pressing operation. During the pressing process, the mold does not shake or shift, effectively avoiding problems such as edge cracking and dimensional deviations in the blank due to uneven stress, thus improving the forming accuracy and pass rate of the insulator blank.

Description

Technical Field

[0001] This utility model relates to the field of insulator production technology, and in particular to a blank pressing machine for producing high-voltage insulators. Background Technology

[0002] Insulators, as core insulating components of power systems, are widely used in overhead transmission lines, substations, and other applications. They must operate for extended periods under high voltage, strong electric fields, and complex natural environments (such as wind, rain, icing, and pollution), placing stringent requirements on their insulation performance, mechanical strength, and structural stability. Currently, ceramic insulators are the most widely used type in power systems. Their production process encompasses key stages such as raw material preparation, pressing, high-temperature calcination, and surface treatment. Among these, pressing is the core process that determines the density, dimensional accuracy, and subsequent yield of the insulator blank, and the pressing machine is the core equipment in this process.

[0003] In the prior art, such as Chinese Patent No. CN220357884U, a workbench is included. A support plate is fixedly connected to the top surface of the workbench. The support plate is L-shaped. A hydraulic cylinder is fixedly installed on the top surface of the support plate. The output end of the hydraulic cylinder passes through the support plate and is movably connected to it. A pressure plate is fixedly connected to the output end of the hydraulic cylinder. Support rods are fixedly connected to the bottom surface of the workbench near the four corners. A pressing mold is provided on the upper side of the workbench. Fabric is provided inside the pressing mold. A positioning component is provided on the side wall of the pressing mold. A spray component is also provided on the side wall of the pressing mold. It can achieve the following: by spraying atomized water on the surface of the blank, the blank will not stick to the mold during the pressing process, thereby improving the yield of insulator blanks.

[0004] While the above solutions have the advantages mentioned above, their disadvantages are that the existing positioning components require manual disassembly of bolts to replace the mold, which is cumbersome and the positioning accuracy depends on manual labor. In addition, the distance between the existing positioning rods cannot be adjusted, so they can only be adapted to one size of pressing mold. If a new size mold is required, the entire worktable and positioning components need to be replaced, which increases the equipment investment. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing positioning components require manual disassembly of bolts to replace molds, which is cumbersome and the positioning accuracy depends on manual operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pressing machine for producing high-voltage insulators: including a workbench, the pressing machine for producing high-voltage insulators further includes: Two chutes are provided on both sides of the top of the worktable; Four sliders are slidably installed in two groups inside the two grooves; Four support plates are mounted on top of the plurality of sliders; Two fixing rods are respectively installed between the two opposing support plates; The blank pressing mold is located in the middle between the two fixed rods; Four fixing plates are installed in two groups on both sides of the pressing mold; Adjusting components are disposed inside the two slide grooves; Multiple quick-release components are mounted on the fixed plate.

[0007] In a preferred embodiment, the adjusting member includes: A limiting rod is fixedly installed inside one of the slide grooves; The limiting rod passes through two of the sliders, and the two sliders slide in cooperation with the limiting rod. A bidirectional lead screw is rotatably mounted inside another of the aforementioned grooves; The bidirectional lead screw passes through the other two sliders and is threadedly connected to the two sliders.

[0008] The technical effect of adopting the above-mentioned further solution is as follows: by connecting the two-way lead screw and the slider with a thread, the slider can move precisely in opposite directions using the two reverse threads of the lead screw. With the guide constraint of the limit rod on the slider, the slider is prevented from deviating when sliding, ensuring the stability and accuracy of the distance adjustment between the support plate and the fixed rod. This enables the centering positioning of the pressing mold, adapts to the installation requirements of molds of different specifications, and provides a stable benchmark for subsequent pressing of the blank.

[0009] In a preferred embodiment, the adjusting member further includes: The motor is mounted on one side of the worktable; The output end of the motor is connected to one end of a bidirectional lead screw via a coupling.

[0010] The technical effect of adopting the above-mentioned further solution is as follows: using an electric motor as a power source, the torque is stably transmitted to the bidirectional lead screw through a coupling, replacing manual adjustment and realizing automated control of slider movement. This not only reduces the labor intensity of operators, but also accurately controls the lead screw speed and rotation angle, keeping the slider spacing adjustment error within a small range, improving mold positioning efficiency and accuracy, and adapting to the pace of large-scale production.

[0011] In a preferred embodiment, the quick-release component includes: A rotating plate is hinged to the top of the fixed plate; The mounting box is installed at the bottom of the rotating plate; Two storage tubes are installed on both sides of the mounting box; Two limiting posts are slidably installed at both ends of the two storage cylinders; A slot is provided on one side of the fixing plate; The mounting box and storage tube are adapted to the card slot; Telescopic components are installed inside the mounting box and the storage tube.

[0012] The technical advantages of adopting the above-mentioned further solution are as follows: with the help of the hinge structure of the rotating plate and the fixed plate, the initial docking of the mounting box and the slot can be achieved by quick flipping. The storage tube provides sliding space for the limiting column. With the help of the telescopic component to drive the limiting column to extend or retract, the locking or unlocking of the mold and the fixed plate can be completed quickly without disassembling a large number of bolts, which greatly shortens the time for mold replacement and fixing and improves the ease of operation of the equipment.

[0013] In a preferred embodiment, the telescopic member includes: The mounting slot is formed inside the mounting box; A gear is disposed in the middle of the mounting groove; Two racks are respectively installed at the top and bottom of the two limiting posts; The two racks mesh with the gear; The motor is mounted on one side of the mounting slot; The output end of the motor is connected to the middle part of the gear; The heat dissipation holes are located on the side of the mounting box closest to the motor.

[0014] The technical effects of adopting the above-mentioned further solution are as follows: by driving the gear to rotate by the motor, the rotational motion of the motor is converted into the linear motion of the limit post by the meshing transmission of the gear and rack, so as to realize the automatic extension and retraction of the limit post, ensure that the locking force is uniform and stable, and avoid the locking loosening or overtightening caused by manual operation; the heat dissipation holes can dissipate the heat generated by the motor operation in time, prevent the motor from being damaged due to high temperature overload, extend the service life of the extension part, and ensure the long-term stable operation of the quick-release part.

[0015] In a preferred embodiment, the telescopic member further includes: Multiple through holes are provided at the top and bottom of the mounting box and the two storage tubes; Among them, multiple through holes are coaxially arranged, the two racks slide with the multiple through holes, and the multiple through holes are connected to the mounting groove; Two storage slots are respectively provided at the top and bottom of the two limiting posts; Both of the racks are adapted to the receiving groove.

[0016] The technical effects of adopting the above-mentioned further solutions are as follows: the coaxial through hole provides precise guidance for the rack sliding, avoiding offset and jamming during rack transmission, and ensuring smooth extension and retraction of the limit post; the storage groove can store the rack when it is reset, preventing the rack from being exposed and worn or interfering with the rotation plate flipping, while avoiding damage caused by friction between the rack and the inner wall of the mounting box and storage cylinder, ensuring the transmission accuracy and integrity of the telescopic component; the design of the through hole and the mounting groove also facilitates rack installation and subsequent maintenance and repair.

[0017] In a preferred embodiment, the high-voltage insulator production blank press further includes: Multiple handles are installed on one side of the rotating plate.

[0018] The technical effects of adopting the above-mentioned further solution are: the pull handle provides the operator with a convenient force application point for flipping the rotating plate, without the need to directly contact the mounting box or limit post, avoiding damage caused by friction between the hand and the part. At the same time, the operator can accurately control the flipping angle and speed of the rotating plate by holding the pull handle, ensuring that the mounting box is stably embedded into the slot, improving the safety and convenience of quick-assembly operation, especially when frequently changing molds, it can effectively reduce the difficulty of operation and fatigue.

[0019] In a preferred embodiment, the high-voltage insulator production blank press further includes: Fabric is placed inside the pressing mold.

[0020] The technical effect of adopting the above-mentioned further solution is that the fabric can isolate the blank from direct contact with the inner wall of the mold, reduce surface scratches or adhesion caused by friction during blank pressing, and ensure the smoothness of the blank surface.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention, through the cooperation of a bidirectional lead screw and a limiting rod, allows for flexible adjustment of the spacing between the slider, support plate, and fixing rod. It can adapt to high-voltage insulator blank pressing molds of different diameters and heights, eliminating the need to replace the entire support structure, thus reducing equipment investment costs. It is suitable for small-batch, multi-variety insulator production scenarios. Simultaneously, the guiding effect of the limiting rod on the slider prevents support structure misalignment, ensuring the pressing mold remains centered during the pressing process. The mold remains stable and unwavering during pressing, effectively preventing edge cracking and dimensional deviations caused by uneven stress on the blank, thereby improving the forming accuracy and yield of the insulator blank.

[0022] This utility model features a quick-release component that automatically locks via a motor-driven gear and rack transmission, eliminating the need for manual tightening of bolts or clips. After the limiting post extends through the gear and rack transmission, it forms a rigid abutment with the inner wall of the slot. Combined with the positioning of the pre-adjustment component, it reduces the displacement error of the pressing mold and avoids uneven stress on the blank material caused by mold shaking during the pressing process. At the same time, the double fixing structure (adjustment component and quick-release component) can disperse the impact of pressing pressure on the mold, reduce mold deformation, and ensure the dimensional accuracy and surface smoothness of the insulator blank.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please see Figures 1-4 This embodiment provides a blank pressing machine for producing high-voltage insulators, and its specific concept is as follows: A high-voltage insulator production blank pressing machine includes a workbench 1, and the high-voltage insulator production blank pressing machine also includes: two slide grooves 8, four sliders 9, four support plates 6, two fixed rods 3, blank pressing mold 10, four fixed plates 4 and adjusting components.

[0027] The two slides 8 are located on both sides of the top of the worktable 1.

[0028] Among them, the four sliders 9, which play the role of adjusting the distance, are installed in two groups inside the two slide grooves 8.

[0029] The four support plates 6 are installed on top of the multiple sliders 9.

[0030] Among them, the two fixing rods 3, which play a fixing role, are respectively installed between the two opposite support plates 6.

[0031] The pressing mold 10 is located in the middle between the two fixed rods 3.

[0032] The four fixing plates 4, which play a fixing role, are installed in two groups on both sides of the pressing mold 10.

[0033] The adjustable components are located inside the two slide grooves 8.

[0034] As examples, in this embodiment, the adjusting components include: a limiting rod 7, a bidirectional lead screw 11, and a motor 2.

[0035] The limiting rod 7, which serves as a limiting element, is fixedly installed inside one of the slide grooves 8.

[0036] It should be noted that the limiting rod 7 passes through two of the sliders 9, and the two sliders 9 slide in conjunction with the limiting rod 7.

[0037] The bidirectional lead screw 11, which plays an adjusting role, is rotatably installed inside another slide groove 8.

[0038] In addition, the bidirectional lead screw 11 passes through the other two sliders 9, and the bidirectional lead screw 11 is threadedly connected to the two sliders 9.

[0039] The motor 2 is installed on one side of the workbench 1.

[0040] In addition, the output end of motor 2 is connected to one end of the double-acting lead screw 11 via a coupling.

[0041] In this embodiment, when it is necessary to adapt to insulator blanks of different specifications, the motor 2 on one side of the workbench 1 is started. The output torque of the motor 2 is transmitted to the bidirectional lead screw 11 in the corresponding slide groove 8 through the coupling, causing the bidirectional lead screw 11 to rotate around its own axis. Since the bidirectional lead screw 11 is threadedly connected to the two sliders 9 in the slide groove 8, and the two ends of the lead screw have opposite threads, a reverse driving force is generated on the two sliders 9 during rotation, causing the sliders 9 to move in opposite directions along the slide groove 8. At the same time, the two sliders 9 in the other slide groove 8 are sleeved on the fixed limiting rod 7. Under the guidance and constraint of the limiting rod 7, they move synchronously with the sliders 9 on the side of the bidirectional lead screw 11, avoiding the sliders 9 from shifting and causing the support structure to tilt. The support plate 6 and the sliders 9 move synchronously to adjust the distance, thereby causing the two fixed rods 3 connected between the relative support plates 6 to change the distance, so that the distance between the fixed rods 3 matches the outer diameter of the different pressing molds 10, completing the positioning and fixing of the mold, and providing a stable working reference for subsequent blank pressing.

[0042] Example 2: Please see Figures 1-4 Based on Example 1, this example provides a blank pressing machine for producing high-voltage insulators, the specific idea of ​​which is as follows: The high-voltage insulator production blanking machine also includes: multiple handles 14, fabric 21 and multiple quick-assembly parts.

[0043] The multiple handles 14 are all installed on one side of the rotating plate 13.

[0044] The fabric 21 is located inside the pressing mold 10.

[0045] The various quick-release components are all mounted on the fixed plate 4.

[0046] As examples, in this embodiment, the quick-release component includes: a rotating plate 13, a mounting box 16, two storage tubes 12, two limiting posts 17, a slot 15, and a telescopic component.

[0047] The rotating plate 13 is hinged to the top of the fixed plate 4.

[0048] The mounting box 16 is installed at the bottom of the rotating plate 13.

[0049] Two storage tubes 12, which serve a storage function, are installed on both sides of the mounting box 16.

[0050] Among them, the two limiting posts 17, which play a limiting role, are slidably installed at both ends of the two storage cylinders 12.

[0051] The card slot 15, which serves as a limit, is located on one side of the fixing plate 4.

[0052] In addition, the mounting box 16 and the storage tube 12 are compatible with the slot 15.

[0053] The telescopic components are installed inside the mounting box 16 and the storage tube 12.

[0054] As examples, in this embodiment, the telescopic component includes: a mounting slot 23, a gear 22, two racks 18, a motor 19, a heat dissipation hole, multiple through holes 24, and two storage slots 20.

[0055] The mounting slot 23 is located inside the mounting box 16.

[0056] The gear 22 is located in the middle of the mounting groove 23.

[0057] The two racks 18 are respectively installed at the top and bottom of the two limiting posts 17.

[0058] In addition, the two racks 18 mesh with the gears 22.

[0059] The motor 19, which plays a driving role, is installed on one side of the mounting slot 23.

[0060] In addition, the output end of the motor 19 is connected to the middle of the gear 22.

[0061] The heat dissipation holes, which serve to dissipate heat, are located on the side of the mounting box 16 closest to the motor 19.

[0062] The multiple through holes 24 are provided at the top and bottom of the mounting box 16 and the two storage tubes 12.

[0063] It should be noted that the multiple through holes 24 are coaxially arranged, the two racks 18 slide with the multiple through holes 24, and the multiple through holes 24 are connected to the mounting groove 23.

[0064] Among them, the two storage slots 20, which serve a storage function, are respectively opened at the top and bottom of the two limiting posts 17.

[0065] It should be noted that both racks 18 are adapted to the storage slots 20.

[0066] In this embodiment, the operator holds the handle 14 on one side of the rotating plate 13 and flips the rotating plate 13 downwards by means of the hinge structure between the rotating plate 13 and the top of the fixed plate 4. During this process, the mounting box 16 at the bottom of the rotating plate 13 and the storage cylinders 12 on both sides move synchronously until they are embedded in the slot 15 on one side of the fixed plate 4. The motor 19 in the mounting box 16 is started. The output end of the motor 19 drives the gear 22 in the middle of the mounting groove 23 to rotate. Since the gear 22 meshes with the racks 18 at the top and bottom of the two limiting posts 17, and the racks 18 pass through the coaxial through holes 24 on the mounting box 16 and the storage cylinders 12 (the through holes 24 play a guiding and constraining role to prevent the racks 18 from deviating), when the gear 22 rotates, it will drive the two racks 18 to move in the opposite direction along the mounting groove 23, thereby driving the limiting posts 17 to extend from both ends of the storage cylinders 12 and tightly abut against the inner wall of the slot 15, completing the rigid locking of the quick-mounting part to the fixed plate 4 and further fixing the pressing mold 10.

[0067] Working principle: During use, the position and fixed state of the pressing mold 10 need to be adjusted according to the size of the insulator blank to be pressed, ensuring that the mold is centered and stable. The motor 2 installed on one side of the workbench 1 is started. The output end of the motor 2 drives the bidirectional lead screw 11 in the slide groove 8 on the other side to rotate through the coupling. Since the bidirectional lead screw 11 is threadedly connected to the two sliders 9 in the corresponding slide groove 8 and the threads are symmetrical, the rotation of the lead screw will drive the two sliders 9 to slide in opposite directions along the slide groove 8. At the same time, the two sliders 9 in the slide groove 8 on the other side are sleeved on the fixed limiting rod 7 and slide synchronously with the former. The limiting rod 7 plays a guiding role to prevent the sliders 9 from deviating. The support plate 6 on the top of the slider 9 moves synchronously with the slider 9, thereby driving the two fixed rods 3 connected between the relative support plates 6 to adjust the spacing. When the spacing of the fixed rods 3 matches the size of the pressing mold 10, the motor 2 is turned off.

[0068] Then, the fixing plates 4 on both sides of the quick-assembly part pressing mold 10 are installed on the fixing rod 3 to prevent the mold from shifting during the pressing process. The operator uses the pull handle 14 on one side of the rotating plate 13 to flip the rotating plate 13, which is hinged to the top of the fixing plate 4, downward, so that the mounting box 16 at the bottom of the rotating plate 13 and the storage cylinders 12 on both sides are embedded into the slot 15 on one side of the fixing plate 4, initially achieving the fitting and positioning of the rotating plate 13 and the fixing plate 4. Then, the motor 19 in the mounting box 16 is started. The output end of the motor 19 drives the gear 22 in the middle of the mounting groove 23 to rotate. Since the gear 22 meshes with the racks 18 at the top and bottom of the two limit posts 17, when the gear 22 rotates, it will drive the two racks 18 to slide in opposite directions along the mounting groove 23, and the racks 18 passes through the coaxial through hole 24 on the storage cylinder 12 and the mounting box 16. The through hole 24 acts as a guide, thereby driving the two limiting posts 17 to extend from both ends of the storage cylinder 12 and tightly abut against the inner wall of the slot 15 to complete the rigid locking of the mold. If unlocking is required, simply start the motor 19 in reverse. The gear 22 drives the rack 18 to reset, and the limiting posts 17 retract into the storage cylinder 12. The storage slots 20 at the top and bottom of the limiting posts 17 can accommodate the rack 18 when it resets, ensuring that the limiting posts 17 are completely retracted and do not affect the rotation of the rotating plate 13. Then, the rotating plate 13 can be rotated by pulling the handle 14. At the same time, the heat generated by the motor 19 during operation is discharged through the heat dissipation holes on the side of the mounting box 16 to avoid high temperature affecting the life of the components.

[0069] After the mold is fixed, the pressing operation of the insulator blank can be carried out. The cloth 21 and the pressing mold 10 work together to ensure the integrity of the blank. The pre-prepared insulator blank is placed on the cloth 21 inside the pressing mold 10. The cloth 21 plays a buffering and anti-sticking role, reducing the probability of the blank sticking to the mold.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
