Specific embodiments

[0029] 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 of 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.

[0030] As Figure 1-8 shown, the present utility model provides a technical solution: a PVC water pipe flaring device, including a machine platform 1. Traveling wheels 13 and liftable support legs 14 are respectively arranged at the bottom of the machine platform 1. The entire device can be pushed to move through the traveling wheels 13, and the device can be fixed on the ground by adjusting the support legs 14 to make them touch the ground.

[0031] A cover body 2 surrounded by three panels is arranged on the top of the machine platform 1. The front of the cover body 2 is a conveying channel, so it is designed as an open structure.

[0032] A pipe conveying rack 3 is arranged on the back of the cover body 2. The pipe conveying rack 3 is in a "Z" - shaped structure, so more pipes can be stacked. And the angle of the bottom - most conveying rack is relatively gentle, generally with an inclination not higher than 8 degrees. The purpose of this design is to facilitate the unloading column 72 to control the movement of each pipe one by one, so that it is not the case that multiple pipes enter the lower die 6 at one time. The discharge port of the pipe conveying rack 3 is located inside the cover body 2, and a distribution box 4 is arranged on the side of the machine platform 1.

[0033] A flaring seat 5 is arranged in the center of the top of the machine platform 1. The flaring seat 5 is located inside the cover body 2. A lower die 6 is arranged on the top of the flaring seat 5. A lower die groove 61 is opened on the lower die 6, and a pipe unloading assembly 7 is arranged on the flaring seat 5.

[0034] The pipe unloading assembly 7 includes a liftable unloading cylinder 71. The free end of the unloading cylinder 71 is equipped with an unloading column 72. One side of the unloading column 72 abuts against the pipe, and the other side is in contact with the lower die 6. On the side of the unloading column 72 close to the lower die 6, an unloading claw 73 is integrally formed. The unloading claw 73 is embedded in the lower die 6 and can move up and down in the lower die groove 61, so as to eject the pipe from the lower die groove 61.

[0035] At the top of the cover body 2, a mold closing assembly 8 is provided which can be lifted. The mold closing assembly 8 includes a liftable first cylinder 81. The free end of the first cylinder 81 is equipped with an upper die 82. An upper die groove 83 matching the lower die groove 61 is formed on the upper die 82.

[0036] On one side of the lower die 6 away from the pipe conveying rack 3, an inclined downward conveying plate 9 is provided. Below the conveying plate 9, a discharging plate 10 is provided.

[0037] On one side of the cover body 2, a second cylinder 11 is provided. The free end of the second cylinder 11 is equipped with an expanding head 12. The expanding nozzle part of the expanding head 12 is conical in shape, and a heating cavity 121 is arranged in the expanding nozzle. An electric heating wire 122 is arranged in the heating cavity 121, and water is contained in the heating cavity 121. In order to facilitate the expanding of the pipe, the water in the heating cavity 121 is heated in advance by the electric heating wire 122, so as to raise the temperature of the expanding nozzle part. Using the principle of thermal expansion and contraction, the expansion of the pipe port can be accelerated, thus facilitating the expanding.

[0038] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0039] During use, first, the pipes are stacked on the pipe conveying rack 3 in sequence. Then, the unloading cylinder 71 is started to drive the unloading column 72 to move downward, thus opening the conveying channel between the pipes on the pipe conveying rack 3 and the lower die 6. The lowermost pipe directly slides into the lower die groove 61 in the lower die 6. After that, the unloading column 72 resets to separate the conveying channel.

[0040] Then, the first cylinder 81 is started to drive the upper die 82 to descend and close the mold with the lower die 6, so as to firmly fix the pipe in the mold. After that, the second cylinder 11 is started to drive the expanding head 12 to move and enter the pipe port to perform the expanding operation on the pipe.

[0041] After the expanding is completed, first, the first cylinder 81 is used to drive the upper die 82 away from the lower die 6. The unloading cylinder 71 is started to drive the unloading column 72 to move upward, so as to drive the unloading claw 73 in the lower die groove 61 to rise, and then drive the pipe in the lower die groove 61 to leave the lower die. After the pipe leaves the lower die 6, it automatically slides off the unloading claw 73 onto the conveying plate 9 and finally slides out through the discharging plate 10. After that, the unloading cylinder 71 is started again to drive the unloading column 72 to move downward, so that the second pipe enters the lower die 6, and the process is repeated in sequence.

[0042] In summary, for this PVC pipe flaring device, by setting the upper and lower molds that can be opened and closed, the pipe can be firmly fixed on the working station, effectively avoiding the problem of pipe slippage. Further, by setting the liftable pipe unloading assembly, the pipe after flaring can be quickly unloaded and a new pipe can be automatically introduced onto the working station, thus achieving the purpose of automatic loading and unloading of pipes. The total working hours of this device from loading a pipe to flaring and unloading this pipe are at least two-thirds less than those of traditional devices, improving production efficiency.
