Description

Technical Field

[0001] This utility model relates to the technical field of flaring devices for CPVC cable pipe production, and in particular to a flaring device for CPVC cable pipe production. Background Technology

[0002] CPVC cable conduit, also known as CPVC power conduit, is commonly used as a cable protection pipe. This product has the characteristics of high strength, good flexibility, high temperature resistance, corrosion resistance, flame retardancy, good insulation performance, no pollution, not easy to age, light weight, and convenient construction. During the production process of CPVC cable conduit, a flaring device is needed to flare the ends of the conduit.

[0003] A cable conduit flaring device, as disclosed in utility model patent application CN208247448U, includes a placement frame, a heating component and a flaring component located at one end of the placement frame, and a clamping and conveying component at the other end of the placement frame for sequentially moving the conduit from the placement frame to the heating component and the flaring component. A conduit conveying component is located on the side of the heating component away from the flaring component. The conduit conveying component, the heating component, and the flaring component are arranged side-by-side at one end of the clamping and conveying component. While this device facilitates the continuous flaring process, making it convenient to transport and place the conduit on the placement frame after it has been manufactured, it also results in higher labor costs and lower efficiency. However, this device shares similarities with most existing CPVC cable conduit flaring devices in use, namely, the flaring mold size is fixed, which limits its ability to flare CPVC cable conduits of different diameters, thus restricting its application range. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a flaring device for CPVC cable pipe production. However, this device has the same characteristics as most existing CPVC cable pipe flaring devices when in use, namely, the size of the flaring mold is fixed, which cannot effectively flare CPVC cable pipes of different diameters, thus resulting in a relatively limited range of applications.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flaring device for CPVC cable pipe production, including a workbench, a first bracket fixedly connected to the upper end of the workbench, a first electric telescopic rod provided at the upper end of the first bracket, a connecting plate fixedly connected to the output end of the first electric telescopic rod, three slots provided on the connecting plate, the three slots respectively cooperating with the inserts on one side of the first mold, the second mold and the third mold, and a limiting hole provided on one side of the inserts, an L-shaped plate fixedly connected to one side of the connecting plate, a crossbar passing through the L-shaped plate, a handle fixedly connected to one end of the crossbar, a spring fixedly connected between the handle and the L-shaped plate, and a fixing plate fixedly connected to the other end of the crossbar, three limiting rods fixedly connected to one side of the fixing plate, the limiting rods cooperating with the limiting holes, a second electric telescopic rod provided at the upper end of the workbench, the output end of the second electric telescopic rod fixedly connected to a sliding plate, and a fixing component provided on the sliding plate.

[0006] As a preferred technical solution of this utility model, the fixing component is as follows: a second bracket is fixedly connected to the upper end of the slide plate, a motor is provided at the upper end of the second bracket, the output end of the motor passes through the second bracket and is fixedly connected to a bidirectional lead screw, one end of the bidirectional lead screw is rotatably connected to the slide plate, and a pair of limiting plates are threadedly connected to the bidirectional lead screw, one end of the limiting plate is inserted into a limiting groove on one side of the second bracket, a support plate and a pressure plate are fixedly connected to one end of the two limiting plates respectively, and a placement plate is fixedly connected to the upper end of the support plate.

[0007] As a preferred embodiment of this utility model, anti-slip pads are provided on one side of both the placement plate and the pressure plate.

[0008] As a preferred embodiment of this utility model, the worktable is provided with a through hole.

[0009] As a preferred technical solution of this utility model, the first mold, the second mold, and the third mold are all different in size and specifications.

[0010] As a preferred embodiment of this utility model, a control panel is provided at the upper end of the workbench.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are: By placing the heat-treated CPVC cable pipe onto the upper part of the placement plate and then starting the motor, the motor drives the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw causes two limiting plates to move towards each other. Under the limiting action of the limiting groove, the limiting plates can move well, and at the same time, the pressure plate can press and fix the CPVC cable pipe on the placement plate. Simultaneously, a suitable mold is selected according to the diameter of the CPVC cable pipe. The first electric telescopic rod is activated, causing the connecting plate and three molds to move downwards until the appropriate mold is at the same height as the CPVC cable pipe. Then, the second electric telescopic rod is activated, causing the sliding plate to move to one side, indirectly moving the CPVC cable pipe closer to the mold, thus effectively flaring the CPVC cable pipe. Furthermore, when it is necessary to replace the three molds, the handle can be pulled, causing the handle to move the crossbar and fixing plate to one side, while the spring extends until the limiting rod leaves the limiting hole, thus allowing the insert block to leave the slot and enabling the replacement of the corresponding mold. This device can effectively flare CPVC cable pipes of different diameters, thereby increasing the device's applicability. Attached Figure Description

[0013] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort. Example

[0014] Please refer to Figures 1-3 As shown, this utility model provides a flaring device for CPVC cable pipe production. Anti-slip pads are provided on one side of the placement plate 26 and the pressure plate 27, so that the CPVC cable pipe can be fixed well. The workbench 1 has a through hole 17. The first mold 6, the second mold 7 and the third mold 8 are all different in size and specifications. The upper end of the workbench 1 is provided with a control panel 28. The control panel 28, the first electric telescopic rod 3, the second electric telescopic rod 18 and the motor 21 on this device are all electrically connected to an external power source and are all controlled by the control panel 28.

[0015] As a further implementation of this embodiment, such as Figures 1-4 As shown, a first support 2 is fixedly connected to the upper end of the workbench 1. A first electric telescopic rod 3 is provided at the upper end of the first support 2. A connecting plate 4 is fixedly connected to the output end of the first electric telescopic rod 3. Three slots 5 are provided on the connecting plate 4. The three slots 5 respectively cooperate with the inserts 9 on one side of the first mold 6, the second mold 7, and the third mold 8. A limit hole 10 is provided on one side of the insert 9. An L-shaped plate 11 is fixedly connected to one side of the connecting plate 4. A crossbar 12 is passed through the L-shaped plate 11. A handle 13 is fixedly connected to one end of the crossbar 12. A spring 14 is fixedly connected between the handle 13 and the L-shaped plate 11. A fixing plate 15 is fixedly connected to the other end of the crossbar 12. Three limit rods 16 are fixedly connected to one side of the fixing plate 15. The limit rods 16 and the limit holes In conjunction with 10, a second electric telescopic rod 18 is provided at the upper end of the workbench 1. The output end of the second electric telescopic rod 18 is fixedly connected to the slide plate 19, and a fixing component is provided on the slide plate 19. The fixing component is as follows: a second bracket 20 is fixedly connected to the upper end of the slide plate 19, and a motor 21 is provided at the upper end of the second bracket 20. The output end of the motor 21 passes through the second bracket 20 and is fixedly connected to the bidirectional lead screw 22. One end of the bidirectional lead screw 22 is rotatably connected to the slide plate 19, and a pair of limiting plates 23 are threadedly connected to the bidirectional lead screw 22. One end of the limiting plate 23 is inserted into the limiting groove 24 on one side of the second bracket 20. One end of the two limiting plates 23 is fixedly connected to a support plate 25 and a pressure plate 27, respectively. A placement plate 26 is fixedly connected to the upper end of the support plate 25.

[0016] In use, the heat-treated CPVC cable pipe is placed on the upper end of the placement plate 26, and then the motor 21 is started. The motor 21 drives the bidirectional lead screw 22 to rotate, which in turn drives the two limiting plates 23 to move towards each other. The limiting plates 23 can move well under the limiting action of the limiting grooves 24. Simultaneously, the pressure plate 27 presses and fixes the CPVC cable pipe on the placement plate 26. At the same time, a suitable mold is selected according to the diameter of the CPVC cable pipe, i.e., the first electric telescopic rod 3 is started, which drives the connecting plate 4 and the three molds downwards until the appropriately sized mold is at the same height as the CPVC cable pipe. Activating the second electric telescopic rod 18 causes the slide plate 19 to move to one side, indirectly bringing the CPVC cable pipe closer to the mold for flaring. When the three molds need to be replaced, pulling the handle 13 moves the crossbar 12 and the fixing plate 15 to one side, simultaneously extending the spring 14 until the limit rod 16 leaves the limit hole 10, allowing the insert block 9 to leave the slot 5 for mold replacement. This device effectively flares CPVC cable pipes of different diameters, expanding its application range.

[0017] Specific working principle: In use, the heat-treated CPVC cable pipe is placed on the upper end of the placement plate 26, and then the motor 21 is started. The motor 21 drives the bidirectional lead screw 22 to rotate. The rotation of the bidirectional lead screw 22 can drive the two limiting plates 23 to move towards each other. Under the limiting action of the limiting groove 24, the limiting plates 23 can move well. At the same time, the pressure plate 27 can press and fix the CPVC cable pipe on the placement plate 26. At the same time, according to the diameter of the CPVC cable pipe, a suitable mold is selected, that is, the first electric telescopic rod 3 is started. The first electric telescopic rod 3 can drive the connecting plate 4 and the three molds to move downward until the mold of the appropriate size is at the height of the CPVC cable pipe. The device works in unison, and the second electric telescopic rod 18 is activated, causing the slide plate 19 to move to one side. This indirectly moves the CPVC cable pipe closer to the mold, allowing for proper flaring of the CPVC cable pipe. Additionally, when the three molds need to be replaced, the handle 13 is pulled, causing the crossbar 12 and the fixing plate 15 to move to one side. Simultaneously, the spring 14 extends until the limit rod 16 leaves the limit hole 10, allowing the insert block 9 to leave the slot 5, thus facilitating the replacement of the corresponding mold. This device can effectively flare CPVC cable pipes of different diameters, thereby expanding its application range.
