Description
Technical Field
[0001] The utility model relates to the technical field of pipe processing, in particular to a CPVC power pipe making machine. Background Technique
[0002] CPVC power pipe, fully known as chlorinated polyvinyl chloride power pipe, is a kind of pipe commonly used for cable protection.
[0003] During the processing of CPVC power pipe making, it is necessary to perform flaring treatment on the pipe orifice, that is, to expand the end of the plastic pipe so as to connect with other pipes or fittings.
[0004] In the current flaring operation, usually the whole pipe body is heated to make it soft, and then the flaring head is inserted into it for flaring treatment. However, in the above method, the critical position where the pipe body is softened by heat, that is, the junction between the hard part and the softened part of the pipe body, will be wrinkled and bent under the extrusion pressure of the flaring head, thus causing unnecessary deformation of the pipe body.
[0005] Therefore, we propose a CPVC power pipe making machine to solve the existing problems. Content of the Utility Model
[0006] The purpose of the utility model is to propose a CPVC power pipe making machine aiming at the problems existing in the background technique.
[0007] To achieve the above purpose, the utility model provides the following technical solution: a CPVC power pipe making machine, including a machine table and a pipe body. One side of the upper surface of the machine table is provided with a surrounding frame. The upper end of the surrounding frame is provided with an upper die in a lifting manner. The lower end of the surrounding frame is provided with a lower die. A positioning component is provided on the opposite surfaces of the lower die and the upper die. The pipe body is clamped and positioned on the surrounding frame through the positioning component. The other side of the upper surface of the machine table is provided with a substrate. A frame body is telescopically provided on the substrate. A punch is threaded at the center of the frame body. A processing component is provided on the frame body. A pressure-bearing component is provided on the machine table.
[0008] Preferably, the positioning component is composed of arc blocks and pin rods with the same center and different radii. Each arc block with the same center and different radii is respectively arranged on the opposite surfaces of the lower die and the upper die through pin rods.
[0009] Preferably, an upper air cylinder is provided at the top end of the surrounding frame. The output end of the upper air cylinder penetrates through the surrounding frame and is arranged on the upper surface of the upper die.
[0010] Preferably, the processing component is composed of an electric heating ring and a spraying ring. The electric heating ring is arranged on the frame body. The spraying ring is arranged on the electric heating ring.
[0011] Preferably, the maximum diameter of the punch is the target inner diameter of the flared CPVC power pipe, and the position of the electric heating ring corresponds to the position of the tapered neck of the punch.
[0012] Preferably, the pressure-bearing assembly is composed of a pressure-bearing frame, roller shafts, sliding rods and screws. The screw is threadedly arranged on the machine table, the pressure-bearing frame is rotatably arranged at the top of the screw, the sliding rod is arranged on the lower surface of the pressure-bearing frame and is slidably inserted into the machine table, and each roller shaft is equidistantly rotatably arranged on the upper surface of the pressure-bearing frame and is in rolling contact with the pipe body.
[0013] Preferably, a side cylinder is installed on the substrate, and the output end of the side cylinder penetrates through the substrate and is arranged on the frame body.
[0014] Preferably, support seats are arranged on the lower surface of the machine table. There are four support seats in total, and the positions of the four support seats are distributed in a rectangular array on the lower surface of the machine table.
[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0016] During the use of the CPVC power pipe making machine of the present utility model, the pipe body of the CPVC power pipe to be processed can be inserted between the upper die and the lower die, and then the upper cylinder operates to perform a die closing action to fix the position of the pipe body. Further, arc blocks with corresponding inner diameters can be selected according to the diameter of the pipe body;
[0017] Subsequently, the side cylinder works, driving the punch and the electric heating ring to approach the end opening of the pipe body uniformly. During this process, after the tapered neck of the punch first enters the pipe body, the electric heating ring works to heat and soften the pipe body at this time, and then the punching part of the punch enters the pipe body to punch the pipe body. Through the cooperation of the above steps, the electric heating ring uniformly heats the pipe body locally, and the moving speed of the punch is the same as that of the electric heating ring, ensuring that the softening speed of the pipe body is adapted to the advancing speed of the punch, so that the pipe body is softened and flared at the same time.

Detailed implementation manners
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0027] Embodiment 1
[0028] As Figures 1 - 5 shown, a CPVC power pipe making machine proposed by the present utility model includes a machine table 1 and a pipe body 6. A surrounding frame 5 is provided on one side of the upper surface of the machine table 1. An upper die 9 is provided at the upper end of the surrounding frame 5 in a lifting manner. A lower die 8 is provided at the lower end of the surrounding frame 5. A positioning component is provided on the opposite surface of the lower die 8 and the upper die 9. The pipe body 6 is clamped and positioned on the surrounding frame 5 through the positioning component. A substrate 3 is provided on the other side of the upper surface of the machine table 1. A frame body 14 is telescopically provided on the substrate 3. A punch 4 is threadedly provided at the center of the frame body 14. A processing component is provided on the frame body 14. A pressure-bearing component is provided on the machine table 1.
[0029] Based on Embodiment 1:
[0030] During the use of the CPVC power pipe making machine of the present utility model, the CPVC power pipe body 6 to be processed can be inserted between the upper die 9 and the lower die 8. Subsequently, the upper air cylinder 11 operates to perform a die closing action to fix the position of the pipe body 6. Further, arc blocks 10 with corresponding inner diameters can be selected according to the diameter of the pipe body 6;
[0031] Subsequently, the rear cylinder 13 operates, driving the punch 4 and the electric heating ring 15 to approach the end opening of the pipe body 6 at a uniform speed. During this process, after the tapered neck of the punch 4 first enters the pipe body 6, the electric heating ring 15 operates to heat and soften the pipe body 6. Subsequently, the punching part of the punch 4 enters the pipe body 6 to punch the pipe body 6. Through the cooperation of the above steps, the electric heating ring 15 uniformly heats the pipe body 6 locally, and the moving speed of the punch 4 is consistent with the moving speed of the electric heating ring 15, ensuring that the softening speed of the pipe body 6 is adapted to the advancing speed of the punch 4, enabling the pipe body 6 to be flared while being softened. Compared with the operation of first heating the whole pipe and then flaring it, the present utility model can avoid the overlong softening part of the pipe body 6 and prevent the phenomenon of wrinkles and bending at the junction of the hard part and the soft part of the pipe body 6 when punching. Further, after the flaring is completed, an external water pump structure is connected to make atomized water droplets spray out from the spray ring 16 and fall on the flared position of the pipe body 6 to cool it, thus completing the flaring and pipe manufacturing operation of the CPVC power pipe.
[0032] Embodiment 2
[0033] As Figures 1 - 5 shown, a CPVC power pipe manufacturing machine proposed by the present utility model, compared with Embodiment 1, further includes: a positioning component composed of arc blocks 10 with different radii but the same center and pin rods 12. Each arc block 10 with different radii but the same center is respectively arranged on the opposite surfaces of the lower die 8 and the upper die 9 through the pin rods 12, and arc blocks 10 with corresponding inner diameters can be selected according to the diameter of the pipe body 6.
[0034] An upper cylinder 11 is arranged at the top of the surrounding frame 5. The output end of the upper cylinder 11 penetrates the surrounding frame 5 and is arranged on the upper surface of the upper die 9. The upper cylinder 11 operates to drive the upper die 9 to move up and down, completing the opening and closing die actions of the mold.
[0035] The processing component is composed of an electric heating ring 15 and a spray ring 16. The electric heating ring 15 is arranged on the frame body 14, and the spray ring 16 is arranged on the electric heating ring 15. The maximum diameter of the punch 4 is the target inner diameter of the flare of the CPVC power pipe. The position of the electric heating ring 15 corresponds to the position of the tapered neck of the punch 4. The electric heating ring 15 uniformly heats the pipe body 6 locally, and the moving speed of the punch 4 is consistent with the moving speed of the electric heating ring 15, ensuring that the softening speed of the pipe body 6 is adapted to the advancing speed of the punch 4, enabling the pipe body 6 to be flared while being softened.
[0036] The pressure-bearing assembly is composed of a pressure-bearing frame 7, roller shafts 17, sliding rods 18, and a screw rod 19. The screw rod 19 is threadedly arranged on the machine table 1.

Each roller shaft 17 is rotatably arranged at equal intervals on the upper surface of the pressure-bearing frame 7 and is in rolling contact with the pipe body 6. When the position of the pipe body 6 is positioned between the molds, the screw rod 19 can be rotated. Under the principle of the lead screw, the pressure-bearing frame 7 moves upward, so that the roller shafts 17 abut against the outer wall of the pipe body 6, thereby providing support for the pipe body 6.
[0037] A side cylinder 13 is installed on the base plate 3. The output end of the side cylinder 13 penetrates through the base plate 3 and is arranged on the frame body 14. When the side cylinder 13 works, it drives the frame body 14 to perform telescopic translational motion.
[0038] Support seats 2 are arranged on the lower surface of the machine table 1. There are four support seats 2 in total, and the positions of the four support seats 2 are distributed in a rectangular array on the lower surface of the machine table 1.
