Technical Field
[0001] The utility model relates to the technical field of plastic pipe flaring, in particular to a plastic pipe interface processing device. Background Technique
[0002] Plastic pipe flaring, as a common pipe connection method, mainly refers to processing the end of a plastic pipe to make its diameter larger to meet connection requirements or achieve other specific functions. The principle is that during the flaring process, a specific flaring tool or device is usually used to heat and soften the pipe end, and then it is expanded outward by mechanical force or hydraulic pressure to form a certain trumpet-shaped or conical opening.
[0003] In the prior art, the flaring of plastic pipes is basically carried out with an electric soldering iron. After the pipe orifice is heated and softened by the electric soldering iron, the flaring work is completed with flaring columns of different specifications according to different processing requirements. However, during the transfer from the softening by the electric soldering iron to the flaring column, the pipe is prone to touch and deform, resulting in the deviation of the formed flare.
[0004] In view of the above technical defects, a solution is proposed. Content of the Utility Model
[0005] The purpose of the utility model is to provide a plastic pipe interface processing device to solve the problem that the plastic pipe is prone to deformation during the flaring process after the port is softened.
[0006] The purpose of the utility model can be realized by the following technical scheme: A plastic pipe interface processing device includes a base and an outer cylinder connected by threads, and the outer cylinder is sleeved outside the base. The front end of the outer cylinder is open. A fixed cylinder facing the front side is installed inside the front end of the base. A large soldering ring, a medium soldering ring and a small soldering ring are successively connected to the front side of the fixed cylinder. An inclined platform one is commonly connected between the medium soldering ring and the small soldering ring. An inclined platform two is commonly connected between the large soldering ring and the medium soldering ring. A heater is installed at the bottom inside the fixed cylinder, and a conduction rod connected to the large soldering ring, the medium soldering ring and the small soldering ring is installed at the output end of the heater.
[0007] Preferably, a cooling sleeve with an open front side is installed at the front end of the outer cylinder. Slots are commonly opened on both sides of the cooling sleeve. The slot is a "U"-shaped opening structure. Open boxes are installed at both the upper and lower ends of the inner ring side of the cooling sleeve.
[0008] Preferably, the two ends of the open box do not coincide horizontally with the slot, and a blower facing the inside is embedded at the bottom inside the open box. A blade is installed at the output end of the blower.
[0009] Preferably, a plurality of screw bolts are symmetrically installed on both sides of the upper and lower ends of the front end of the outer cylinder, and the screw bolts are threadedly connected to the outer cylinder and extend to the inner end to be rotatably connected to a limiting semi-ring.
[0010] Preferably, the circular ring structure composed of the upper and lower groups of the limiting semi-rings are respectively matched with the outer ring surfaces of the large ring, the middle ring and the small ring, and the limiting semi-rings are stainless steel semi-ring structures.
[0011] Preferably, the inclination angles of ramp one and ramp two are both 45°, and the middle melting ring and small melting ring, and the large melting ring and middle melting ring are smoothly connected through ramp one and ramp two respectively.
[0012] Preferably, a handle is connected to the rear end of the base, a plurality of angle grooves are formed at the lower end of the handle, and the outer tube is a transparent structure.
[0013] Beneficial effects of the utility model:
[0014] (1) The utility model can complete the expansion operation of plastic pipes of multiple sizes by setting a multi-stage softening and expanding structure, and the purpose of slow expansion and limited deformation is achieved by a continuous diameter expansion structure and a limit mechanism during expansion, specifically as follows: the heater is started to accurately conduct heat to the large soldering ring, the middle soldering ring and the small soldering ring through the conduction rod, at which time the plastic pipe openings sleeved on the large soldering ring, the middle soldering ring and the small soldering ring are heated and softened, and after softening, the plastic pipe is pushed inward, and the plastic pipe first passes through the inclined platform 1 or the inclined platform 2. During the process of the plastic pipe opening moving inward, the plastic pipe opening is expanded by the inclined platform 1 or the inclined platform 2 with a continuously increasing diameter, until it moves to the next level of outer diameter and the expansion is completed, at which time the plastic pipe opening is separated from the heating area of the large soldering ring, the middle soldering ring and the small soldering ring and stops softening, and is slowly cooled on the "next level" platform in the non-heating area;
[0015] (2) After the plastic tube softens and expands, the expanded part of the plastic tube leaves the heating area and stops softening, and completes slow cooling (i.e., primary cooling) on the "next level" platform of the non-heating area. After a period of slow cooling, the plastic tube is pulled out, and the expanded part of the plastic tube mouth is inserted into the slot. The slots at both ends provide support for the plastic tube and then the fan is started. The fan drives the rotor to rotate, thereby achieving secondary cooling of the expanded part of the plastic tube mouth after the initial cooling. During the secondary cooling process, the plastic tube can be slowly rotated to achieve uniform cooling of the expanded part of the plastic tube, thereby avoiding deformation caused by touch when the plastic tube is still in a softened state after expansion.

[0024] 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.
[0025] Embodiment 1: This embodiment is used to solve the problem that the plastic pipe port is prone to deformation during the process of softening and flaring after the port is softened.
[0026] Please refer to Figure 1 - Figure 6 As shown in the figure, this embodiment is a plastic pipe interface processing device, including a base 8 and an outer cylinder 1 connected by threads, and the outer cylinder 1 is sleeved outside the base 8. The front end of the outer cylinder 1 is open. The inner front end of the base 8 is provided with a fixed cylinder 13 facing the front side. The front side of the fixed cylinder 13 is sequentially connected with a large ironing ring 14, a medium ironing ring 15 and a small ironing ring 16. A first inclined platform 17 is commonly connected between the medium ironing ring 15 and the small ironing ring 16, and a second inclined platform 18 is commonly connected between the large ironing ring 14 and the medium ironing ring 15. A heater 9 is installed at the inner bottom of the fixed cylinder 13, and a conduction rod 10 connected to the large ironing ring 14, the medium ironing ring 15 and the small ironing ring 16 is installed at the output end of the heater 9;
[0027] A plurality of screw bolts 7 are symmetrically installed on the upper and lower sides of the front end of the outer tube 1. The screw bolts 7 are threadedly connected to the outer tube 1 and the ends extending to the inside are rotatably connected to the limiting semi-rings 12. The circular ring structure composed of the upper and lower groups of limiting semi-rings 12 are respectively matched with the outer ring surfaces of the large iron ring 14, the middle iron ring 15 and the small iron ring 16. The limiting semi-rings 12 are stainless steel semi-ring structures.
[0028] The inclination angles of the first ramp 17 and the second ramp 18 are both 45°, and the middle melting ring 15 and the small melting ring 16, and the large melting ring 14 and the middle melting ring 15 are smoothly connected by the first ramp 17 and the second ramp 18, respectively. The rear end of the base 8 is connected with a handle 2, and a plurality of angle grooves are provided at the lower end of the handle 2. The outer tube 1 is a transparent structure. The setting of the transparent outer tube 1 can facilitate clear viewing of the plastic tube during the softening and expanding process of the interface, and quickly interrupt when softening or expanding fails;
[0029] See also Figure 1 - Figure 4 As shown, when the expansion operation of the plastic pipe mouth is performed: according to the expansion requirements of the plastic pipe mouth, a large melting ring 14, a medium melting ring 15 or a small melting ring 16 is inserted in the gap between the outer tube 1 and the fixed tube 13 in advance, and the corresponding expansion requirements are processed to a wider level, and after softening, the ring moves to a wider level to complete the expansion operation;
[0030] The expansion operation process is as follows: start the heater 9 to accurately conduct heat to the large soldering ring 14, the middle soldering ring 15 and the small soldering ring 16 through the conduction rod 10. At this time, the plastic pipe mouths sleeved on the large soldering ring 14, the middle soldering ring 15 and the small soldering ring 16 are heated and softened. After softening, the plastic pipe is pushed inward. The plastic pipe first passes through the inclined platform 17 or the inclined platform 2 18. During the process of the plastic pipe mouth moving inward, the plastic pipe mouth is expanded by the inclined platform 17 or the inclined platform 2 18 with a continuously increasing diameter until it moves to the next level of outer diameter and the expansion is completed. At this time, the plastic pipe mouth is out of the heating area of the large soldering ring 14, the middle soldering ring 15 and the small soldering ring 16 and stops softening, and completes slow cooling on the "next level" platform with a non-heating area;
[0031] It is important to note that: during the softening process, by twisting a pair of twisting bolts 9 corresponding to the vertical position of the plastic tube, the twisting bolts 9 rotate and drive the limiting semi-ring 12 to approach and abut against the softened part of the plastic tube. When the plastic tube is softened by heat, the limiting semi-ring 12 attached to the outer side is used to complete the shaping and softening, thereby preventing the plastic tube from deforming during the softening process. Since the limiting semi-ring 12 does not adhere to the plastic tube, it can limit deformation and provide a stable placement function to avoid the problem of softening collapse.
[0032] In summary, the softening and flaring treatment of the plastic pipe interface is carried out continuously to avoid the situation of touching and deformation.
[0033] Embodiment 2: This embodiment is used to solve the problem of how to quickly cool the plastic pipe after the pipe orifice flaring operation is completed.
[0034] Please refer to Figure 1 , Figure 2 and Figure 6 As shown, a plastic pipe interface processing device in this embodiment includes a cooling sleeve 3 with a front-side opening installed at the front end of an outer cylinder 1. Slots 6 are commonly formed on both sides of the cooling sleeve 3. The slot 6 has a "U"-shaped opening structure. Open boxes 5 are installed at both the upper and lower ends of the inner ring side of the cooling sleeve 3. The two ends of the open box 5 do not horizontally coincide with the slot 6, and a blower 4 facing the inside is embedded at the inner bottom of the open box 5. A blade 11 is installed at the output end of the blower 4;
[0035] Please refer to Figure 1 , Figure 2 As shown, after slowly cooling for a period of time, the plastic pipe is pulled outwards, and the flared part of the plastic pipe orifice is inserted into the slot 6. After the two ends of the slot 6 provide support for the plastic pipe, the blower 4 is started. The blower 4 drives the rotating blade 11 to rotate, realizing the secondary cooling after the flared part of the plastic pipe orifice is initially cooled. During the secondary cooling process, the plastic pipe can be slowly rotated to achieve the purpose of uniform cooling of the flared part of the plastic pipe;
[0036] When performing the flaring operation on multiple plastic pipes, the cooling time is used as the preheating interval for the large baking ring 14, the medium baking ring 15, and the small baking ring 16, so as to reduce the interval time of the flaring operation of multiple plastic pipe orifices and make the flaring operation continuous.
[0037] Combining Embodiment 1 and Embodiment 2, it can not only utilize the setting of the multi-stage softening and flaring structure to complete the flaring operation of plastic pipes of multiple sizes, and achieve the purpose of slow flaring and deformation limitation through the continuous diameter expansion structure and the limiting mechanism during flaring, but also utilize the additional auxiliary cooling structure to realize the double cooling after the plastic pipe is flared, further avoiding the situation that the plastic pipe is still in a softened state and encounters touching and deformation after flaring; the two are combined, and this plastic pipe interface processing device can solve the problem of deformation during the flaring process after softening, and achieve the purpose of quickly putting the plastic pipe interface into use after double cooling structure treatment after flaring.
[0038] The process and principle of the present utility model:
[0039] Step 1: Start the heater 9 to accurately conduct heat to the large baking ring 14, the medium baking ring 15, and the small baking ring 16 through the conduction rod 10. At this time, the plastic pipe orifice sleeved on the large baking ring 14, the medium baking ring 15, and the small baking ring 16 is heated and softened;
[0040] Step 2: After softening, the plastic tube is pushed inwards, and the plastic tube first passes through the inclined platform 17 or the inclined platform 2 18. During the process of the plastic tube mouth moving inwards, the plastic tube mouth is expanded by the inclined platform 17 or the inclined platform 2 18 with a continuously increasing diameter, until it moves to the next level of outer diameter and the expansion is completed;
[0041] Step 3: The plastic pipe mouth leaves the heating area of the large soldering ring 14, the middle soldering ring 15 and the small soldering ring 16 and stops softening, and completes slow cooling on the "next level" platform in the non-heating area. After slow cooling for a period of time, the plastic pipe is pulled out, and the expanded part of the plastic pipe mouth is inserted into the slot 6. After the slots 6 at both ends provide support for the plastic pipe, the fan 4 is started, and the fan 4 drives the rotor 11 to rotate, so as to achieve secondary cooling of the expanded part of the plastic pipe mouth after the initial cooling.

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
