Description

Technical Field

[0001] This invention belongs to the field of electrical insulation accessories processing technology, specifically relating to a detachable, non-marking silicone rubber climbing umbrella skirt and its processing equipment and process. Background Technology

[0002] In the field of power transmission and transformation engineering, the creepage distance of core insulating boards such as insulators and insulating bushings directly determines their insulation protection capability. During outdoor operation, dust, salt, alkali, dirt and other impurities easily adhere to the equipment surface, making them highly susceptible to flashover accidents such as pollution flashover and rain flashover in humid, rainy or snowy weather, which can lead to power grid failures. To effectively extend the creepage distance on the surface of the insulating board and improve the insulation protection level, the industry generally adopts the method of adding creepage skirts to the outside of the insulating board to achieve insulation reinforcement.

[0003] Traditional umbrella skirts often adopt an integral closed-loop structure or a simple straight-line cut design. During installation, additional fasteners such as adhesives, metal clips, and nails are required for fixation. Some require open flame heating for bonding, which not only results in low construction efficiency, but also leaves glue residue and clip marks during later maintenance and replacement, making it impossible to achieve seamless disassembly and damaging the insulation board itself.

[0004] Therefore, there is a need to provide a detachable, non-marking silicone rubber climbing umbrella skirt and its processing equipment and process to solve the above-mentioned technical problems. Summary of the Invention

[0016] A process for manufacturing a detachable, seamless silicone rubber climbing umbrella skirt includes the following steps: S1. Insulating silicone rubber raw material is used, along with reinforcing agent, anti-aging agent, color masterbatch and vulcanizing agent. The mixture is mixed evenly in an internal mixer to obtain a compound that meets the injection requirements. The compound is then fed into the barrel of the injection molding machine for preheating and plasticizing to ensure that the compound has the required flowability. S2. The plasticized rubber material is injected into the special molding mold for umbrella skirts at high speed through an injection machine. The mold cavity corresponds to the overall outer contour and mounting hole structure of the umbrella skirt. After the mold is closed, the preset pressure and temperature are maintained to carry out in-mold pressure vulcanization and shaping, resulting in a complete umbrella skirt semi-finished product without openings or overlapping structures. After the mold is opened, the semi-finished product is smoothly ejected by the ejection mechanism. S3. Place the cooled umbrella skirt semi-finished product stably on the positioning mold of the processing table to achieve traceless clamping; start the lifting mechanism to make the punching blade descend vertically. During the descent, the auxiliary pressing mechanism will contact the umbrella skirt body semi-finished product first and pre-press the edge of the umbrella skirt body semi-finished product; the punching blade continues to descend and punches an interlocking opening in the radial direction of the umbrella skirt body in one go. The punching waste is discharged directly along the waste chute. After the punching is completed, the equipment is reset and the punched umbrella skirt body is taken out.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through its interlocking opening, allows for easy installation by simply slipping the umbrella skirt body onto the insulating board and then snapping on the interlocking parts. Disassembly is possible by prying it open by hand, requiring no tools, leaving no adhesive residue, and causing no mechanical damage. This truly achieves detachable and traceless installation without damaging the insulating board itself, significantly improving the efficiency of subsequent maintenance and replacement.

[0018] 2. The interlocking opening of this invention adopts a staggered distribution structure of concave and convex interlocking, forming a seamless sealing overlap after closure, which completely solves the problem of dirt accumulation and water seepage in the straight opening gaps of the old umbrella skirt. Combined with the top arc surface hydrophobic guide design, it greatly reduces the probability of dirt adhesion, effectively improves the anti-pollution flashover and anti-rain flashover capabilities, and extends the equipment operation cycle.

[0019] 3. The present invention uses a positioning mold to center and limit the placement of the umbrella skirt body, achieving seamless clamping. Furthermore, with the cooperation of guide rails, pulley seats, and rollers, the lifting frame can drive the punching frame and punching blade to slide smoothly, allowing the punching blade to punch the umbrella skirt body smoothly and without deviation.

[0020] 4. The present invention, through its quick-release mechanism, can quickly replace the punching blade according to the punching requirements of the interlocking opening, adapting to the mass production of multiple umbrella skirt models and greatly improving processing efficiency.

[0021] 5. Through the auxiliary pressing mechanism, this invention enables the pressing plate and buffer pad to contact the umbrella skirt body first before the punching blade punches the umbrella skirt body. With the cooperation of the slide rod and the compression spring assembly, the umbrella skirt body can be pre-pressed, which facilitates the punching blade to accurately punch the umbrella skirt body.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1 Please see Figure 1-2 This embodiment provides the following technical solution: a detachable, traceless silicone rubber climbing umbrella skirt, including an umbrella skirt body 1. The umbrella skirt body 1 is generally a circular disc or elliptical structure, and the bottom of the umbrella skirt body 1 is a flat and fitting plane, the top of the umbrella skirt body 1 is an outwardly convex arc surface that extends gently outward, and the middle of the umbrella skirt body 1 is provided with a long strip mounting hole 2 adapted to an insulating plate.

[0025] The umbrella skirt body 1 has an interlocking opening 3 along its radial direction that communicates with the mounting hole 2. On both sides of the interlocking opening 3, there are multiple sets of staggered protruding parts 31 and concave parts 32. The protruding parts 31 and concave parts 32 interlock with each other to achieve self-closing and locking. After closing, a complete closed-loop structure is formed. There are no exposed gaps at the opening, forming a sealed overlapping structure. Through the interlocking opening 3, the umbrella skirt body 1 can be directly put into the insulation board and the interlocking part can be fastened. When disassembling, it can be pried open and separated by hand without tools, adhesive residue, or mechanical damage. It truly achieves detachable and traceless installation without damaging the insulation board body, and greatly improves the efficiency of later maintenance and replacement.

[0026] The outer edge and corners of the protruding part 31 are provided with a first arc-shaped chamfer 33, which facilitates smooth engagement when the interlocking opening 3 is engaged, avoids the corners from scratching the outer wall of the insulation board, and reduces stress concentration at the silicone corners to prevent cracking after long-term use.

[0027] During installation and use, gently pry open the interlocking opening 3, and insert the umbrella skirt body 1 through the elongated mounting hole 2 onto the outside of the target insulating rod. After loosening, the protruding part 31 and the concave part 32 automatically engage and lock together, without the need to apply adhesive or add fasteners. The flat bottom surface fits tightly against the outer wall of the insulating rod. When disassembling, simply pry open the interlocking opening 3 from the edge to release the concave-convex engagement state and remove the umbrella skirt. There are no traces left throughout the process.

[0028] Example 2 like Figures 3-9 As shown, a detachable, traceless silicone rubber climbing umbrella skirt processing device includes a processing table 4. The processing table 4 is provided with a positioning mold 5 for placing the umbrella skirt body 1. The positioning mold 5 includes a positioning plate 51 and a clamping plate 52. The positioning plate 51 is fixedly connected to the processing table 4. A waste groove 12 is opened on the positioning plate 51, and the waste groove 12 passes through the positioning plate 51 and the processing table 4 in sequence. Several clamping plates 52 are fixedly connected to the outer edge of the positioning plate 51 at intervals. The inner wall of the clamping plate 52 is adapted to the outer wall of the umbrella skirt body 1. With the cooperation of the positioning plate 51 and the clamping plate 52, the umbrella skirt body 1 can be centered and limited after placement, realizing traceless clamping. Furthermore, the top edge of the clamping plate 52 is provided with a second arc-shaped chamfer 53 to prevent the edge of the clamping plate 52 from scratching the umbrella skirt body 1 when the umbrella skirt body 1 is placed on the positioning plate 51, thus affecting the quality of the umbrella skirt body 1.

[0029] A punching frame 6 is vertically slidably connected to the right side of the positioning mold 5. A punching template 7 is fixedly connected to the punching frame 6. A punching knife 8 is provided on the punching template 7. The punching knife 8 is located directly above the waste trough 12, and the outer diameter of the punching knife 8 is smaller than the inner diameter of the waste trough 12. After the punching knife 8 moves down to punch the umbrella skirt body 1, the waste generated by punching is discharged along the waste trough 12 to avoid affecting the subsequent punching of the umbrella skirt body 1.

[0030] like Figure 3 , Figure 4 and Figure 5As shown, a lifting mechanism 9 is provided on the processing table 4. The lifting mechanism 9 includes a fixed frame 91, which is fixedly connected to the right side of the processing table 4. A telescopic device 92 is fixedly connected to the top of the fixed frame 91. In some embodiments, the telescopic device 92 is either an electric push rod or a hydraulic cylinder. The movable end of the telescopic device 92 is fixedly connected to a lifting frame 93 that is slidably connected to the fixed frame 91. Guide rails 94 are fixedly connected to both the front and rear sides of the lifting frame 93 on the fixed frame 91. The guide rails 94 extend along the height of the fixed frame 91. In this configuration, a pulley seat 95 is provided between the lifting frame 93 and the guide rail 94. The side of the pulley seat 95 facing the lifting frame 93 is fixedly connected to the lifting frame 93, and multiple rollers 96 are rotatably connected to the other side of the pulley seat 95. The rollers 96 are located inside the guide rail 94 and are slidably connected to the guide rail 94. Through the provided telescopic device 92, the lifting frame 93 can drive the punching frame 6, the punching template 7 and the punching blade 8 to slide smoothly in the vertical direction along the guide rail 94, so that the punching blade 8 can punch the umbrella skirt body 1 smoothly and without deviation.

[0031] In use, simply place the semi-finished umbrella skirt body 1 into the positioning mold 5, then start the telescopic device 92, so that the lifting frame 93 drives the punching frame 6, punching template 7 and punching blade 8 to move vertically downward. With the cooperation of the pulley seat 95, roller 96 and guide rail 94, the punching frame 6, punching template 7 and punching blade 8 move smoothly downward until the punching blade 8 completes the punching of the umbrella skirt body 1, thereby punching the required interlocking opening 3 on the umbrella skirt body 1. The waste generated by punching will be discharged along the waste groove 12 on the positioning mold 5 and the processing table 4. After the punching is completed, the punching blade 8 is reset.

[0032] The punching blade 8 is connected to the punching template 7 via a quick-release mechanism 10. The quick-release mechanism 10 includes multiple locking plates 101 distributed along the axial direction of the punching blade 8. The locking plates 101 are fixedly connected to the punching blade 8. The top of the locking plate 101 passes through the locking cavity 102 provided on the punching template 7 and is slidably connected to the punching template 7. The top edge of the locking plate 101 is provided with a third arc-shaped chamfer 103. When installing the punching blade 8, simply drag the punching blade 8 so that each locking plate 101 is inserted from below the punching template 7 into the corresponding locking cavity 102 on the punching template 7. Then, through the locking assembly above the punching template 7, each locking plate 101 can be locked and fixed on the punching template 7. This allows for quick replacement of the punching blade 8 according to the punching requirements of the interlocking opening 3, adapting to the mass production of multiple models of umbrella skirts and greatly improving processing efficiency.

[0033] like Figure 6 , Figure 7 and Figure 8As shown, the locking assembly includes a locking frame 104, which is horizontally slidably connected to the punching template 7. A handle 105 is fixedly connected to the locking frame 104. In some embodiments, the locking frame 104 includes two parallel drive rods, with the two ends of the drive rods fixedly connected by a connecting rod. A positioning pin 106 is fixedly connected to the side of each drive rod opposite to each locking plate 101. During the sliding of the two drive rods in the same direction, the positioning pin 106 can be movably inserted into the corresponding positioning hole 107 on the locking plate 101. Thus, during the movement of the drive rods driven by the handle 105, all the positioning pins 106 can be simultaneously inserted into or simultaneously disengaged from the corresponding positioning hole 107.

[0034] A plurality of limiting rods 108 are also provided on one side of the locking frame 104. The plurality of limiting rods 108 are fixedly connected to one of the driving rods and are arranged perpendicular to the driving rods. The limiting rods 108 are arranged parallel to the connecting rods. The other end of the limiting rods 108 is fixedly connected to the limiting rings 1011. Each limiting rod 108 is movably sleeved with two limiting seats 109 that are fixedly connected to the punching die. A set of return springs 1010 is provided between the two limiting seats 109 and sleeved on the limiting rods 108. One end of the set of return springs 1010 is fixedly connected to one of the limiting seats 109, and the other end of the set of return springs 1010 is fixed to the limiting rods 108. The connection, with the cooperation of the limiting rod 108 and the limiting seat 109, can limit the locking frame 104 in the horizontal direction, so that the positioning pin 106 can be horizontally inserted into or disengaged from the positioning hole 107 on the locking plate 101. Under the action of the return spring assembly 1010, when the locking frame 104 drives the positioning pin 106 to disengage from the positioning hole 107 on the locking plate 101, the limiting rod 108 moves with the locking frame 104 and compresses the return spring assembly 1010. When the locking frame 104 is released, the limiting rod 108 and the locking frame 104 can be reset, so that the positioning pin 106 can be re-inserted into the corresponding positioning hole 107.

[0035] When the punching blade 8 needs to be replaced, simply pull the handle 105 to make the locking frame 104 drive the limiting rod 108 to slide forward along the limiting seat 109. This will cause all the positioning pins 106 to disengage from the positioning holes 107 on the locking plate 101. At the same time, the return spring assembly 1010 is compressed. After the locking plate 101 disengages from the positioning pins 106, the punching blade 8 can be dragged to disengage the locking plate 101 from the locking cavity 102 on the punching template 7, thus completing the removal of the punching blade 8. After releasing the handle 105, the return spring will reset, causing the locking frame 104 and the positioning pins 106 to reset. Pull the handle 105 again to move the locking frame 104 and the positioning pin 106 away from the locking cavity 102. Then drag the new punching blade 8 so that the locking plate 101 on the punching blade 8 corresponds one-to-one with the locking cavity 102 on each punching template 7 until the locking plate 101 passes through the punching template 7 and the locking cavity 102 on the locking plate 101 is above the punching template 7. Then release the handle 105. Under the action of the return spring assembly 1010, the locking frame 104 drives the positioning pin 106 to reset, so that the positioning pin 106 can be inserted into the positioning hole 107 on the corresponding locking plate 101, and the new punching blade 8 is locked and fixed again.

[0036] Example 3 like Figures 3-8 As shown, the punching template 7 is also provided with multiple auxiliary clamping mechanisms 11, which are symmetrically distributed on both sides of the punching blade 8. Each auxiliary clamping mechanism 11 includes a clamping plate 111, and a buffer pad 112 is fixedly connected to the bottom of the clamping plate 111. The buffer pad 112 is a flexible buffer pad, and its lower surface is adapted to the convex arc surface of the umbrella skirt body 1. Multiple sliding rods 113 are fixedly connected to the top of the clamping plate 111. The top of each sliding rod 113 passes through a groove on the punching template 7 and slides with the punching template 7. The slide rod 113 is slidably connected to the inner wall of the slide groove through a rolling bearing. A compression spring assembly 114 is sleeved on the outer side of the slide rod 113. The top end of the compression spring assembly 114 is fixedly connected to the top end of the slide rod 113, and the bottom end of the compression spring assembly 114 is fixedly connected to the punching template 7. Before the punching knife 8 punches the umbrella skirt body 1, the pressing plate 111 and the buffer pad 112 can be made to contact the umbrella skirt body 1 first. With the cooperation of the slide rod 113 and the compression spring assembly 114, the pre-compression of the umbrella skirt body 1 can be completed, which makes it easier for the punching knife 8 to accurately punch the umbrella skirt body 1.

[0037] In use, before the punching blade 8 contacts the umbrella skirt body 1, the clamping plate 111 and the buffer pad 112 first contact the upper surface of the umbrella skirt body 1. As the punching template 7 continues to move downward, the sliding rod 113 and the compression spring group 114 work together to pre-press the umbrella skirt body 1, which facilitates the punching blade 8 to accurately punch the umbrella skirt body 1. After the punching blade 8 completes the punching, the punching blade 8 gradually slides upward away from the umbrella skirt body 1 until the punching blade 8 is separated from the umbrella skirt body 1. Then the compression spring group 114 gradually resets. Only after the compression spring group 114 is completely reset will the clamping plate 111 gradually detach from the umbrella skirt body 1 along with the punching template 7, so that the punched umbrella skirt body 1 can be removed from the positioning mold 5.

[0038] Example 4 A process for manufacturing a detachable, seamless silicone rubber climbing umbrella skirt includes the following steps: S1. Insulating silicone rubber raw material is used, along with reinforcing agent, anti-aging agent, color masterbatch and vulcanizing agent. The mixture is mixed evenly in an internal mixer to obtain a compound that meets the injection requirements. The compound is then fed into the barrel of the injection molding machine for preheating and plasticizing to ensure that the compound has the required flowability. S2. The plasticized rubber material is injected into the special molding mold for umbrella skirt at high speed through an injection machine. The mold cavity corresponds to the overall outer contour of the umbrella skirt and the structure of mounting hole 2. After the mold is closed, the preset pressure and temperature are maintained to carry out in-mold pressure vulcanization and shaping to obtain a complete umbrella skirt semi-finished product without openings or overlapping structures. After the mold is opened, the semi-finished product is smoothly ejected by the ejection mechanism. S3. Place the cooled umbrella skirt semi-finished product stably on the positioning mold 5 of the processing table 4. The positioning plate 51 and the clamping plate 52 cooperate to complete the centering and limiting, and achieve the markless clamping. Start the telescopic device 92 of the lifting mechanism 9 to drive the lifting frame 93, punching frame 6 and punching template 7 to descend vertically. During the descent, the auxiliary pressing mechanism 11 contacts the semi-finished product first. Under the action of the compression spring group 114, the edge of the semi-finished product is pre-pressed by the pressing plate 111 and the buffer pad 112. The punching knife 8 continues to descend and punches the umbrella skirt body 1 radially to form an interlocking opening 3 in one go. The punching waste is discharged directly along the waste groove 12. After the punching is completed, the equipment is reset and the punched umbrella skirt body 1 is taken out.
