Description

Technical Field

[0001] This invention relates to the field of silicon core tube manufacturing, specifically a flame-retardant high-density polyethylene silicon core tube. Background Technology

[0002] In the construction of telecommunications, power, and municipal pipeline networks, flame-retardant high-density polyethylene (HDPE) silicon core pipes are widely used as protective sheaths for optical cables and electrical cables due to their excellent mechanical properties, corrosion resistance, flame retardancy, and smooth inner wall structure. Silicon core pipes are typically made of high-density polyethylene with added flame retardants, and their inner wall is coated with a silicone layer to reduce frictional resistance during cable installation, thereby significantly improving construction efficiency and extending cable lifespan.

[0003] However, in actual production, silicon core tubes often need to be bent according to engineering requirements to meet the requirements of different laying paths. Traditional bending processes mostly use manual or semi-automatic equipment, which have the following technical drawbacks:

[0004] Insecure fixing: During the bending process, the silicon core tube is prone to displacement or loosening, resulting in inaccurate bending angle, or even deformation or damage to the tube;

[0005] Inefficient: The clamping device and bending mechanism need to be adjusted manually and repeatedly, which is cumbersome and time-consuming.

[0006] Low level of automation: Existing equipment has difficulty in synchronizing clamping and bending actions, relying on manual intervention, which increases production errors and safety risks.

[0007] Furthermore, due to the material properties of flame-retardant HDPE silicon core tubes, uniform force must be applied during bending to avoid localized stress concentration that could lead to pipe wall cracking. However, traditional equipment lacks a dynamic clamping and bending coordinated control mechanism, making it difficult to meet the demands of high-precision processing.

[0008] Therefore, there is an urgent need to develop a device that integrates automatic clamping and bending functions, which can fix the silicon core tube in real time during the bending process, ensuring bending accuracy and efficiency, while adapting to the processing characteristics of flame-retardant HDPE materials, and improving production quality and safety. Summary of the Invention

[0009] The purpose of this invention is to provide a flame-retardant high-density polyethylene silicon core tube to solve the problems mentioned in the background art.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A flame-retardant high-density polyethylene silicon core tube includes a support platform, and a workbench and a bending device are provided on the end face of the support platform. One end of the bending device is located on the surface of the support platform, and the other end is located inside the support platform.

[0012] The support platform is equipped with a drive device, which is connected to a fixing device. The fixing device extends into the worktable and cooperates with the worktable.

[0013] The support platform is equipped with a transmission device. One end of the transmission device is engaged with the drive device, and the other end of the transmission device is engaged with the bending device.

[0014] As a further aspect of the present invention: the bending device includes a support plate, one end of which is fixedly connected to an I-beam slide rail, and the I-beam slide rail is slidably connected to a sliding chuck. One end of the sliding chuck is located outside the support platform, and the other end of the sliding chuck is located inside the support platform. The sliding chuck is in slidable contact with the support platform. A pressure rod is fixedly connected to the end face of the sliding chuck outside the support platform, and the pressure rod cooperates with the worktable.

[0015] As a further embodiment of the present invention: the sliding chuck is provided with a sliding groove in the support platform, the sliding groove and the pressure rod are located on the same side of the sliding chuck, a sliding plate is slidably arranged in the pressure rod, a guide groove is provided at one end of the sliding plate, a toothed rod is provided in the guide groove, and the toothed rod is fixedly connected to the sliding plate.

[0016] As a further aspect of the present invention: the transmission device includes a transmission shaft, one end of which has a toothed groove on its outer surface, the toothed end of which extends into a guide groove, the toothed groove meshing with a toothed rod, and the other end of the transmission shaft is fixedly connected to a second bevel gear, which meshes with a drive device.

[0017] As a further aspect of the present invention: the driving device includes a driving motor, one end of which is rotatably connected to a drive shaft, a first bevel gear is fixedly connected to the outer surface of the middle part of the drive shaft, the first bevel gear meshes with a second bevel gear, and an inclined disk is fixedly connected to the outer surface of the other end of the first bevel gear, the inclined disk cooperating with the fixing device.

[0018] As a further embodiment of the present invention: the fixing device includes a slide rod, one end of which is slidably connected to an inclined disc, and the other end of which extends into the worktable. A feeding groove is provided inside the worktable, and a fixing plate is fixedly connected to the end of the slide rod that extends into the worktable. The fixing plate is located in the feeding groove and slides in contact with the worktable.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: When using this device, the silicon core tube is placed above the fixed plate from the left end of the feeding groove, wherein the length of the silicon core tube extending from the right end of the feeding groove is the bending length. Then, the drive motor is started, and the drive motor controls the rotation of the drive shaft, that is, the rotation of the tilting disc. Since the tilting disc slides in contact with the slide rod, and the tilting disc is tilted, when the drive shaft rotates, the slide rod performs a resetting motion of moving up and down, that is, the slide rod drives the fixed plate to move. The fixed plate cooperates with the worktable to clamp and fix the silicon core tube. While the shaft rotates, the first bevel gear rotates as well. The first bevel gear meshes with the second bevel gear, causing the transmission shaft to rotate. The second bevel gear meshes with the rack through its tooth groove, causing the slide plate to move up and down. That is, the sliding chuck moves up and down along the I-beam slide. The sliding chuck drives the pressure rod to move up and down. The pressure rod bends the silicon core tube by cooperating with the worktable. In other words, while the pressure rod descends to bend the silicon core tube, the fixing plate rises to fix the silicon core tube. This device can effectively clamp and fix the silicon core tube automatically during the bending process. Attached Figure Description

[0031] Example 2

[0032] Please see Figure 1-4 Based on Embodiment 1, the bending device further includes a support plate 4, one end of which is fixedly connected to an I-beam slide rail 5, and the I-beam slide rail 5 is slidably connected to a sliding chuck 6.

The sliding chuck 6 is in sliding contact with the support platform 1, and the end face of the sliding chuck 6 outside the support platform 1 is fixedly connected to a pressure rod 7, which cooperates with the worktable 2.

[0033] Furthermore, the sliding chuck 6 is provided with a sliding groove 17 in the support platform 1. The sliding groove 17 and the pressure rod 7 are located on the same side of the sliding chuck 6. A sliding plate 20 is slidably arranged in the pressure rod 7. A guide groove 18 is provided at one end of the sliding plate 20. A toothed rod 19 is provided in the guide groove 18. The toothed rod 19 is fixedly connected to the sliding plate 20.

[0034] Furthermore, the transmission device includes a transmission shaft 15, one end of which has a toothed groove 14 on its outer surface. The toothed groove 14 extends into the guide groove 18, and the toothed groove 14 meshes with the toothed rod 19. The other end of the transmission shaft 15 is fixedly connected to a second bevel gear 16, which meshes with the drive device. The second bevel gear 16 meshes with the toothed rod 19 through the toothed groove 14, causing the slide plate 20 to move up and down. That is, the sliding chuck 6 moves up and down along the I-beam slide 5 in a reciprocating motion.

[0035] Furthermore, the driving device includes a drive motor 8, one end of which is rotatably connected to a drive shaft 11. A first bevel gear 9 is fixedly connected to the outer surface of the middle part of the drive shaft 11. The first bevel gear 9 meshes with a second bevel gear 16. An inclined disk 10 is fixedly connected to the outer surface of the other end of the first bevel gear 9. The inclined disk 10 cooperates with the fixing device. When the drive shaft 11 rotates, the first bevel gear 9 rotates. The drive shaft 15 rotates by meshing with the second bevel gear 16 through the sliding chuck 6. The inclined disk 10 slides in contact with the slide rod 12. At the same time, the inclined disk 10 is tilted. When the drive shaft 11 rotates, the slide rod 12 performs a reset movement by moving up and down.

[0036] Furthermore, the fixing device includes a slide rod 12, one end of which is slidably connected to the inclined disc 10, and the other end of which extends into the worktable 2. The worktable 2 has a feeding groove 3 inside, and a fixing plate 13 is fixedly connected to the end of the slide rod 12 that extends into the worktable 2. The fixing plate 13 is located in the feeding groove 3, and the silicon core tube is placed above the fixing plate 13 from the left end of the feeding groove 3. The length of the silicon core tube extending from the right end of the feeding groove 3 is the bending length. The fixing plate 13 is in slidable contact with the worktable 2.

[0037] The working principle of this invention is as follows: When using the device, the silicon core tube is placed above the fixed plate 13 from the left end of the feeding groove 3. The length of the silicon core tube extending from the right end of the feeding groove 3 is the bending length. Then, the drive motor 8 is started, and the drive motor 8 controls the rotation of the drive shaft 11, that is, the rotation of the tilting disk 10. Since the tilting disk 10 is in sliding contact with the slide rod 12, and the tilting disk 10 is tilted, when the drive shaft 11 rotates, the slide rod 12 makes a resetting motion by moving up and down, that is, the slide rod 12 drives the fixed plate 13 to move. The fixed plate 13 cooperates with the worktable 2 to clamp and fix the silicon core tube. While rotating, the first bevel gear 9 rotates, and the first bevel gear 9 meshes with the second bevel gear 16 to make the transmission shaft 15 rotate. The second bevel gear 16 meshes with the rack 19 through the tooth groove 14 to make the slide plate 20 move up and down. That is, the sliding chuck 6 moves up and down along the I-shaped slide 5. The sliding chuck 6 drives the pressure rod 7 to move up and down. The pressure rod 7 bends the silicon core tube by cooperating with the worktable 2. That is, while the pressure rod 7 descends to bend the silicon core tube, the fixing plate 13 rises to fix the silicon core tube. This device can effectively clamp and fix the silicon core tube automatically during the bending process.
