Description

Technical Field

[0001] The embodiments of the present invention relate to the field of vulcanization equipment technology, specifically to a lightweight insulator forming and processing equipment. Background Technology

[0002] In power systems, insulators, as crucial insulating components, play a vital role in supporting and insulating electrical equipment. With the development of the power industry, higher demands have been placed on the performance and weight of insulators. Lightweight insulators, due to their advantages such as light weight and ease of installation and transportation, have been widely used in power engineering. Lightweight insulators are typically manufactured by vulcanizing a combination of a core rod and a rubber strip. Currently, existing lightweight insulator molding and processing equipment often requires manual assistance in the vulcanization process of combining and molding mandrels and silicone rubber strips. This is due to the low level of automation. Operations such as placing the mandrel and rubber strips, and removing the molded insulator, are frequently performed manually. Specifically, a rubber strip must first be placed on the lower mold, then the mandrel is placed on top of the rubber strip, and then another rubber strip is placed on top of the mandrel before vulcanization can begin. This process is not only time-consuming, but if continuous, the residual heat of the vulcanizing machine causes the rubber strip initially placed on the lower mold to soften and slightly shrink. Combined with the pressure from the mandrel, this causes premature deformation of the rubber strip on the lower mold. This results in uneven shrinkage of the two rubber strips placed on the upper and lower sides of the mandrel, leading to edge defects and damage to the insulator after vulcanization. The current solution is to use a larger rubber strip to compensate for the shrinkage. While this effectively solves the problem, it results in significant waste of rubber strips and makes demolding and subsequent processing difficult.

[0003] Therefore, there is an urgent need for a lightweight insulator forming and processing equipment that can solve the above problems and achieve efficient and precise production. Summary of the Invention

[0004] To overcome the above-mentioned defects, the present invention provides a lightweight insulator molding and processing equipment, which solves the technical problems of incorrect rubber strip positioning and easy shrinkage of the vulcanizing machine due to heat caused by the method of directly feeding material onto the vulcanizing machine mold in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a lightweight insulator molding and processing apparatus for vulcanizing a core rod and a rubber strip together to form a lightweight insulator, comprising: A vulcanizing machine, on which a mold is mounted; The material rack is hinged to the feed side of the vulcanizing machine via a rotating shaft and is capable of vertical swinging. A placement frame is slidably disposed on the material rack. The placement frame is used to place the core rod and rubber strip to be vulcanized or the molded lightweight insulator. The placement frame can approach the vulcanizing machine by swinging the material rack upwards to deliver the core rod and rubber strip to be vulcanized onto the mold. The placement frame can also drive the formed lightweight insulator to move away from the mold to detach from the mold.

[0006] Optionally, the mold includes a fixed upper mold and a lifting lower mold, both of which have a mold cavity for forming lightweight insulators, and the placement frame can move up and down synchronously with the lifting lower mold.

[0007] Optionally, the rack includes: The rotating shaft is rotatably connected to the outer wall of the lower lifting mold; The side beam has two beams, which are respectively connected to the two ends of the rotating shaft and can swing vertically around the rotating shaft. The side beam has a slide rail that is set along its length and runs horizontally through it. A slider is slidably arranged in the slide rail. The placement frame is fixedly connected to the slider. There are multiple sliders and placement frames, and they are arranged in a one-to-one correspondence.

[0008] Optionally, the side beam has an opening, which is connected to the end of the slide rail away from the pivot. A fixed rod is provided on the feed side of the vulcanizing machine. The fixed rod is arranged parallel to the rotating shaft and located above the rotating shaft. The side beam rod can swing vertically upward around the rotating shaft so that the side beam rod can engage with the fixed rod through the opening. When the opening is engaged with the fixed rod, the side beam rod can move upward with the lifting lower mold. The fixed rod can slide with the slide rail so as to push the slider and the placement frame downward with the help of the fixed rod.

[0009] Optionally, a guide rod is provided on the side of the side beam away from the placement frame. Several collars are slidably arranged on the guide rod. Each collar corresponds to and is fixedly connected to the slider. A spring is provided between adjacent collars. The spring is used to push the collar towards the side closer to the opening.

[0010] Optionally, a sleeve is fitted around the outer periphery of the guide rod, and a receiving space is formed between the sleeve and the guide rod to accommodate the compressed spring. When the opening is engaged with the fixed rod, two adjacent sliders can compress the spring under the action of the fixed rod until the two sliders fit together, so that the multiple placement frames are stacked close to each other.

[0011] Optionally, the plurality of placement frames are as follows: The first placement frame is connected to the side beam and is used to place the core rod; The second placement frame has two frames, which are symmetrically arranged on the upper and lower sides of the first placement frame. The second placement frame is used to place the rubber strip.

[0012] Optionally, the first placement frame has a slot for supporting the mandrel, and the slot engages with the mandrel; the second placement frame is hinged with a retaining plate at each corner, and the retaining plate is used to limit and fix the corner of the rubber strip.

[0013] Optionally, a through hole is provided at the corner of the second placement frame, and an arc-shaped protrusion is provided at one end of the card plate near the through hole. An upwardly extending telescopic top rod is provided on the vulcanizing machine, and a spiral guide groove is provided on the outer peripheral wall of the telescopic top rod. The arc-shaped protrusion slides in cooperation with the spiral guide groove. The telescopic top rod can move upward and extend into the through hole, so as to drive the card plate to swing laterally to disengage from the rubber strip by means of the cooperation between the arc-shaped protrusion and the spiral guide groove.

[0014] Optionally, the feed side of the vulcanizing machine is provided with a diagonal brace, which is used to support the material rack in a horizontal state.

[0015] The beneficial effects of the embodiments of the present invention are as follows: In this invention, before production begins, the operator places the mandrel and rubber strip into the placement frame and fixes them in place. This avoids wrinkles caused by directly placing the rubber strip onto the mold, and the size of the placement frame can also serve as a standard for measuring the amount of rubber strip needed, preventing waste. Then, the material rack begins to swing vertically around the hinge point. As the rack swings, the placement frame gradually moves closer to the vulcanizing machine. When it reaches the designated position, the placement frame is positioned between the two molds. Next, the upper and lower molds of the vulcanizing machine close, and the material inside the molds undergoes vulcanization. After vulcanization, the upper and lower molds open, the material rack swings in the opposite direction, and the placement frame detaches the formed lightweight insulator from the mold, completing one production cycle. This equipment automates the entire process from material conveying to finished product removal. Compared to traditional equipment that requires a large amount of manual assistance for material placement and removal, it significantly improves production efficiency. Meanwhile, because the material can be stably fixed in the placement frame, problems such as rubber strip deformation and inconsistent shrinkage caused by improper manual operation or residual heat of the vulcanizing machine are avoided, thus effectively ensuring the molding quality of the insulator and reducing the defect rate.

[0023] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] like Figures 1-7The diagram illustrates a lightweight insulator molding and processing device according to an embodiment of the present invention. This device is used to combine a core rod and a rubber strip and vulcanize them to form a lightweight insulator. It includes a vulcanizing machine 1, on which a mold 2 is mounted; a material rack 3 is vertically oscillating on the outer wall of the vulcanizing machine 1; and a placement frame 4 is slidably disposed on the material rack 3 along its length. The placement frame 4 is used to place the core rod and rubber strip to be vulcanized, as well as the molded lightweight insulator. The material rack 3 can drive the placement frame 4 to oscillate towards the vulcanizing machine 1, so that the placement frame 4 moves the core rod and rubber strip to be vulcanized onto the mold 2, and the placement frame 4 can also drive the molded lightweight insulator to detach from the mold 2.

[0025] For example, such as Figure 1 and Figure 2 As shown, the vulcanizing machine 1 is constructed of a robust steel structure and contains two molds, upper and lower. Heating elements are installed inside mold 2, which evenly distribute heat, providing a stable temperature environment for insulator vulcanization. Mold 2 is securely bolted to the heating plate, preventing displacement during vulcanization. The material rack 3 is a rectangular frame, with its bottom connected to the outer wall of the vulcanizing machine 1 via a hinge. This allows the material rack 3 to swing vertically around the hinge point to a vertical position; the swing angle is 90°. The placement frame 4 is also a rectangular frame structure, but its area is larger than that of mold 2.

[0026] Before production begins, the operator places the mandrel and rubber strip into the placement frame 4, securing them in place. This prevents wrinkles from forming when the rubber strip is placed directly onto the mold 2, and the size of the placement frame 4 also serves as a standard for measuring the amount of rubber strip needed, avoiding waste. Next, the material rack 3 begins to swing vertically around its hinge point. As the material rack 3 swings, the placement frame 4 gradually moves closer to the vulcanizing machine 1, reaching a position between the two molds 2. Then, the upper and lower molds 2 of the vulcanizing machine 1 close, vulcanizing the material within them. After vulcanization, the upper and lower molds open, and the material rack 3 swings in the opposite direction, causing the placement frame 4 to detach the formed lightweight insulator from the mold 2, completing one full production cycle.

[0027] This equipment automates the entire process from material conveying to finished product removal. Compared to traditional equipment that requires extensive manual assistance for material placement and removal, it significantly improves production efficiency. Furthermore, because the material is stably fixed within the placement frame 4, it avoids problems such as rubber strip deformation and inconsistent shrinkage caused by improper manual operation or residual heat from the vulcanizing machine 1, thus effectively ensuring the molding quality of the insulators and reducing the defect rate.

[0028] In some examples, mold 2 consists of two parts: a fixed upper mold 202 and a lifting lower mold 201. The fixed upper mold 202 is rectangular in shape, and the mold cavity 2011 at the bottom of the fixed upper mold 202 is precisely machined according to the shape of a lightweight insulator. The inner wall of the mold cavity 2011 is finely polished, resulting in a smooth surface with good wear resistance, ensuring a flat and smooth surface on the molded insulator. The lifting lower mold 201 is also rectangular in structure. The guide column of the vulcanizing machine 1 guides the vertical movement of the lifting lower mold 201, ensuring that it does not deviate during the lifting process. The mold cavity 2011 at the top of the lifting lower mold 201 is perfectly matched in shape and size to the mold cavity 2011 of the fixed upper mold 202, and the two molds can form a complete insulator forming space after they are closed. The placement frame 4 can move synchronously with the lifting lower mold 201 without becoming loose during the movement.

[0029] For example, such as Figure 3 As shown, when it is necessary to place the mandrel and rubber strip, the lower lifting mold 201 slowly descends under the action of the drive mechanism, and then deflects the material rack 3 so that the placement frame 4 reaches a height convenient for the operator to place the materials. The operator places the mandrel and rubber strip into the placement frame 4 in sequence. After placement, the material rack 3 swings vertically, the lower lifting mold 201 begins to rise, and the placement frame 4 rises together with the lower lifting mold 201. When the lower lifting mold 201 rises to contact the fixed upper mold 202, the two molds close, forming a closed molding space, and the vulcanizing machine 1 begins to heat and pressurize the material in the mold 2 for vulcanization. After vulcanization, the lower lifting mold 201 descends again, and the placement frame 4 also descends. Then the material rack 3 swings in the opposite direction, and the operator can easily remove the molded insulator from the placement frame 4.

[0030] In some examples, the material rack 3 includes a rotating shaft 32, which is rotatably connected to the outer wall of the lifting lower mold 201; there are two side beams 31, which are respectively set at the two ends of the rotating shaft 32, and the side beams 31 can swing vertically along the rotating shaft 32; a slide rail 310 is provided on the side beams 31 along its length direction, and a slider 33 is slidably arranged in the slide rail 310; the outer wall of the placement frame 4 is fixedly connected to the outer wall of the slider 33; the number of sliders 33 is the same as the number of placement frames 4, and each placement frame 4 corresponds to one slider 33.

[0031] For example, such as Figure 3As shown, the rotating shaft 32 of the material rack 3 is mounted on the outer wall of the lifting lower mold 201 at both ends via bearings. The bearings provide good support and rotation performance, allowing the rotating shaft 32 to rotate smoothly. Two side beams 31 are respectively installed at both ends of the rotating shaft 32. A slide rail 310 is provided on the side beam 31 along its length. The slider 33 is U-shaped and can slide along the slide rail. From the bottom to the top of the slide rail 310, the diameter of the slider 33 gradually decreases. Adjacent sliders 33 can interlock to allow adjacent placement frames 4 to fit together. The four corners of the placement frame 4 are fixedly connected to four sliders 33 by bolts or welding. Each placement frame 4 corresponds to one slider 33, ensuring that the placement frame 4 is firmly and stably installed on the side beams 31.

[0032] During the oscillation process, the placement frame 4 slides slightly within the slide rail 310 via the slider 33. As the side beam 31 oscillates towards the vulcanizing machine 1, the placement frame 4 gradually approaches the mold 2. When the side beam 31 oscillates to a specified angle, the placement frame 4 moves the material above the mold 2. After vulcanization is complete, the side beam 31 oscillates in the opposite direction, and the placement frame 4 moves with the side beam 31. The slider 33 slides within the slide rail 310, removing the formed insulator from the mold 2.

[0033] In some examples, the side beam rod 31 has an opening 311 facing the fixed upper mold 202, and the opening 311 is connected to the slide rail 310; a fixed rod 5 is provided on the outer wall of the top surface of the vulcanizing machine 1, and the fixed rod 5 is arranged parallel to the rotating shaft 32. The side beam rod 31 can swing vertically along the rotating shaft 32 so that the side beam rod 31 is connected to the fixed rod 5 through the opening 311. When the side beam rod 31 moves with the lower mold 201, the side beam rod 31 can move along the fixed rod 5 through the slide rail 310 so that the fixed rod 5 pushes the slider 33.

[0034] For example, such as Figure 3 As shown, the side beam rod 31 has a U-shaped opening 311 on the side facing the fixed upper mold 202. The opening 311 is connected to the slide rail 310, ensuring that the side beam rod 31 can smoothly connect with the fixed rod 5 during the swinging process. The fixed rod 5 is a cylindrical structure, fixedly installed on the outer wall of the top surface of the vulcanizing machine 1. The length of the fixed rod 5 is adapted to the length of the side beam rod 31, and it is arranged parallel to the rotating shaft 32. This allows the side beam rod 31 to fit onto the fixed rod 5 through the opening 311 when it swings to a certain angle, and the side beam rod 31 can slide along the fixed rod 5 within the slide rail 310.

[0035] The side beam 31 begins to swing vertically around the pivot 32. When it swings to a position aligned with the fixed rod 5, the U-shaped opening 311 of the side beam 31 fits onto the fixed rod 5. At this time, the side beam 31 moves along with the lower mold 201. Due to the connection between the side beam 31 and the fixed rod 5, the side beam 31 can move along the fixed rod 5. During the movement, the fixed rod 5 pushes the slider 33, thereby driving the placement frames 4 to move, causing multiple placement frames 4 to move closer to each other and closer to the mold 2. Through the interaction between the fixed rod 5 and the slider 33, the placement frames 4 can accurately place the material onto the mold 2 according to a predetermined path, or remove the formed insulator from the mold 2. When the operation is completed, the side beam 31 swings in the opposite direction, disengaging from the fixed rod 5 and returning to its initial position.

[0036] Compared to the traditional method of controlling the position of the placement frame 4 by simply swinging the material rack 3, the combination of the fixed rod 5 and the slide rail 310 can more accurately control the movement trajectory of the placement frame 4, avoiding inaccurate material placement caused by swing angle errors or other factors. At the same time, the supporting function of the fixed rod 5 can also enhance the stability of the side beam 31 during operation, improving the reliability of equipment operation and the accuracy of production.

[0037] In some examples, a guide rod 34 is provided on the outer wall of the side beam rod 31, and several collars 35 are slidably provided on the guide rod 34. Each collar 35 is fixedly connected to a slider 33, and a spring 36 is provided between adjacent collars 35. The spring 36 is used to push the collar 35.

[0038] For example, such as Figure 3 As shown, two parallel guide rods 34 are fixedly installed on the outer wall of the side beam 31. The guide rods 34 are made of stainless steel with a polished surface, providing good smoothness and wear resistance. Multiple collars 35 are slidably mounted on the guide rods 34. Each collar 35 is fixedly connected to a slider 33 by bolts, ensuring that the collars 35 and sliders 33 can move synchronously. A spring 36 is installed between adjacent collars 35. The spring 36 is a compression spring, with its two ends fixed to the adjacent collars 35. The spring 36 provides sufficient restoring force while ensuring a certain buffering effect between the collars 35. Understandably, after vulcanization, the insulator shell will not be quickly demolded from the mold 2 due to the buffering effect of the spring 36. Instead, the demolding speed will be slow at first and then fast due to the buffering effect of the spring 36. This ensures that the insulator shell will not be damaged due to slight adhesion to the mold cavity 2011. At the same time, since the mandrel is snapped into the placement frame 4, the mandrel will remain on the placement frame 4 when the mold 2 is opened under the action of the spring 36, and will not be damaged due to demolding.

[0039] During the movement of the placement frame 4, when it encounters external forces, such as the pushing of the fixing rod 5 or the mutual compression between multiple placement frames 4, the slider 33 drives the collar 35 to slide on the guide rod 34, and the spring 36 between adjacent collars 35 is compressed. The compression of the spring 36 can absorb the impact of the external force, playing a buffering role and preventing the placement frame 4 from shaking or shifting violently due to excessive impact. When the external force disappears, the spring 36 returns to its deformation, pushing the collar 35, so that the adjacent sliders 33 return to their initial distance, and the placement frame 4 returns to its normal working position. Throughout the process, the guide rod 34 provides stable guidance for the movement of the collar 35 and the slider 33, ensuring the linearity and accuracy of the movement of the placement frame 4.

[0040] The spring 36 and collar 35 provide excellent buffering and resetting functions for the movement of the placement frame 4. During equipment operation, various impacts and vibrations are inevitable. The buffering effect of the spring 36 effectively reduces the impact of these external forces on the placement frame 4 and the material, ensuring the stability of the material during transportation. Simultaneously, the resetting function of the spring 36 allows the placement frame 4 to return to the correct position, improving the equipment's working efficiency and operational reliability.

[0041] In some examples, the bottom of the collar 35 is provided with a sleeve 37, which is used to accommodate the compressed spring 36 so that adjacent sliders 33 fit together after being squeezed.

[0042] For example, such as Figure 3 As shown, a sleeve 37 is fixedly connected to the bottom of the collar 35. The sleeve 37 has a cylindrical structure, with its inner diameter slightly larger than the outer diameter of the spring 36, and its height sufficient to accommodate the length of the spring 36 after maximum compression. When adjacent sliders 33 are pressed together by a large external force, the spring 36 will be compressed and completely housed within the sleeve 37. At this time, the sleeve 37 can protect the spring 36, preventing it from twisting or deforming during compression.

[0043] During equipment operation, when multiple placement frames 4 simultaneously approach the mold 2 to vulcanize materials and form insulators, adjacent sliders 33 will experience significant compressive force. In this situation, sliders 33 drive collars 35 closer together, and springs 36 are compressed and gradually enter the sleeve 37. Due to the restraining effect of the sleeve 37, springs 36 maintain a straight compressed state and do not bend or tilt. When the compressive force disappears, springs 36 recover their deformation within the sleeve 37, pushing collars 35 and sliders 33 back to their original positions, restoring the normal spacing between adjacent sliders 33, and the placement frames 4 return to their normal working state.

[0044] The sleeve 37 provides a safe and reliable storage space for the spring 36, allowing adjacent placement frames 4 to fit together closely after being compressed, facilitating vulcanization. It also prevents the spring 36 from losing its elasticity or becoming damaged due to twisting or deformation, ensuring its long-term stable operation and thus guaranteeing the proper functioning of the placement frames 4's buffering and reset capabilities. Furthermore, the presence of the sleeve 37 makes the equipment structure more compact and rational, reducing potential interference or collision problems caused by exposed springs 36, and improving the safety and stability of equipment operation.

[0045] Strip grooves are made on the two side beams 31, and both ends of the rotating shaft 32 are placed in the strip grooves. Compression springs are installed in the strip grooves. When the lower lifting mold moves up and fits with the fixed upper mold, the compression springs are compressed so that the lower lifting mold and the fixed upper mold fit tightly together.

[0046] In some examples, the placement frame 4 includes a first placement frame 41 for placing the mandrel; there are two second placement frames 42, which are symmetrically arranged on the upper and lower sides of the first placement frame 41, and the second placement frames 42 are used to place the rubber strip.

[0047] For example, such as Figure 3 , Figure 4 and Figure 5 As shown, the placement frame 4 consists of a first placement frame 41 and two second placement frames 42. The first placement frame 41 is rectangular in shape, with a semi-circular groove 410 along its length inside. The size of the groove 410 matches the diameter of the mandrel, allowing it to be tightly secured within. A soft rubber pad is also attached to the inner wall of the groove 410. This rubber pad has good elasticity and can prevent damage to the surface of the mandrel while securing it. The two second placement frames 42 are symmetrically arranged on the upper and lower sides of the first placement frame 41. Both are rectangular frame structures, which can effectively secure the rubber strip and prevent it from sliding within the placement frame 4.

[0048] During the production preparation stage, the operator first places the mandrel into the slot 410 of the first placement frame 41, where both ends of the mandrel are securely held in place by the slot 410 and the rubber pad. Then, rubber strips are placed into the two second placement frames 42, where they are fixed in place by strip-shaped protrusions. After placement, the material rack 3, along with the placement frame 4, transports the material to the mold 2, and the mandrel in the first placement frame 41 and the rubber strips in the second placement frame 42 accurately fall into the mold cavity 2011 of the mold 2. After vulcanization, the placement frame 4 removes the molded insulator from the mold 2, at which point the operator can easily remove the insulator from the placement frame 4.

[0049] The slots 410 and rubber pads in the first placement frame 41 ensure that the mandrel does not rotate or shift during transportation and vulcanization. The strip-shaped protrusions in the second placement frame 42 effectively fix the rubber strip, preventing it from sliding within the placement frame 4. This design ensures the stability of the material within the placement frame 4, thereby guaranteeing the molding quality of the insulator, reducing product defects caused by material displacement, and improving the production pass rate.

[0050] In some examples, the first placement has a slot 410 for engaging with both ends of the mandrel; the corners of the second placement frame 42 are all hinged with a locking plate 43 for fixing the corners of the rubber strip.

[0051] For example, such as Figure 4 As shown, each corner of the second placement frame 42 is fitted with a locking plate 43 via a hinge shaft. The locking plate 43 is elongated, with one end hinged to the corner of the second placement frame 42 and the other end able to rotate around the hinge shaft. The surface of the locking plate 43 is also provided with anti-slip texture, which can increase the friction between it and the rubber strip and better fix the rubber strip.

[0052] When placing the mandrel, align both ends of the mandrel with the positioning grooves at both ends of the slot 410 of the first placement frame 41, and then insert the mandrel into the slot 410. The mandrel is firmly fixed by the slot 410 and the positioning grooves. When placing the rubber strip, first place the rubber strip in the second placement frame 42, aligning its edges and corners with the edges and corners of the second placement frame 42. Then rotate the clamping plate 43 to press down the edges and corners of the rubber strip. The anti-slip texture on the surface of the clamping plate 43 is in close contact with the rubber strip, providing sufficient friction to prevent the rubber strip from moving. When the material rack 3 drives the placement frame 4 to transport the material to the mold 2 and during the vulcanization process, the mandrel and rubber strip can maintain a stable position. After vulcanization, due to the shrinkage process during vulcanization, the clamping plate 43 can be separated from the rubber strip without the operator manually rotating it. The anti-slip texture on the surface of the card plate 43 increases the fixing force on the rubber strip, effectively preventing the rubber strip from sliding or shifting within the placement frame 4, thereby ensuring the molding quality of the insulator and reducing product defects caused by insecure material fixing.

[0053] In some examples, a through hole 420 is provided at the corner of the second placement frame 42, and an arc-shaped protrusion 430 is provided on the card plate 43 near the through hole 420. A telescopic top rod 6 is provided on the vulcanizing machine 1, and a spiral guide groove 601 is provided on the outer peripheral wall of the telescopic top rod 6. The arc-shaped protrusion 430 is slidably connected to the spiral guide groove 601. After the telescopic top rod 6 moves upward and extends into the through hole 420, the arc-shaped protrusion 430 can enter into the spiral guide groove 601, so that the spiral guide groove 601 guides the card plate 43 to deflect and open to the outside of the second placement frame 42.

[0054] For example, such as Figure 4 , Figure 6 and Figure 7 As shown, a circular through hole 420 is provided at the corner of the second placement frame 42, and the diameter of the through hole 420 is slightly larger than the outer diameter of the telescopic top rod 6. An arc-shaped protrusion 430 is provided on the clamping plate 43 near the through hole 420. The arc-shaped protrusion 430 has a hemispherical structure, a smooth surface, and a certain degree of hardness. The telescopic top rod 6 installed on the vulcanizing machine 1 is driven by an electric push rod, and a spiral guide groove 601 is machined on its outer peripheral wall. The pitch and depth of the spiral guide groove 601 are calculated to perfectly match the arc-shaped protrusion 430. A limiting block is also installed at the top of the telescopic top rod 6 to limit its rising height.

[0055] During vulcanization, the telescopic push rod 6 is in a retracted state and does not contact the clamping plate 43. During vulcanization, the telescopic push rod 6, driven by the electric push rod, begins to move upwards, gradually extending into the through hole 420 at the corner of the second placement frame 42. As the telescopic push rod 6 rises, the spiral guide groove 601 on its outer peripheral wall contacts and interacts with the arc-shaped protrusion 430 on the clamping plate 43. Due to the special shape of the spiral guide groove 601, the arc-shaped protrusion 430 experiences a tangential force when sliding within the spiral guide groove 601, causing the clamping plate 43 to deflect and open around the hinge axis to the outside of the second placement frame 42. At this time, because the clamping plate 43 has anti-slip textures inside, it can apply an outward stretching force to the corner of the rubber strip, effectively tightening the rubber strip. This not only prevents the rubber strip from shrinking but also allows the rubber strip to contact the mandrel for vulcanization in a relatively taut state, improving the vulcanization effect. When the telescopic push rod 6 rises to the height limited by the limiting block, the clamping plate 43 fully opens, releasing the fixation of the rubber strip. When it is time to install the next rubber strip, the clamp 43 can be opened manually.

[0056] In some examples, the outer wall of the vulcanizing machine 1 is provided with diagonal bracing rods 7, which are used to support the material rack 3 in a horizontal position.

[0057] For example, such as Figure 6 As shown, a diagonal brace 7 is welded to the outer wall of the vulcanizing machine 1. The diagonal brace 7 is a triangular truss structure, welded from multiple high-strength steel pipes. This structure can reduce its own weight while ensuring strength. One end of the diagonal brace 7 is fixed to the outer wall of the vulcanizing machine 1 by welding, and the other end is equipped with an adjustable support head. The support head has a spherical structure and can make good contact with the surface of the material rack 3. The support head is threaded to the diagonal brace 7, and the operator can adjust its extension length by rotating the support head to adapt to the support requirements of the material rack 3 under different conditions. The triangular truss structure of the diagonal brace 7 can effectively distribute the weight of the material rack 3 and the placement frame 4, ensuring that the material rack 3 remains stable in a horizontal position.
