Description

Technical Field

[0001] This utility model relates to the technical field of plastic pipe fitting processing equipment, specifically a plastic pipe fitting flaring equipment. Background Technology

[0002] Plastic pipe flaring equipment is a processing device used in the production and processing of plastic pipe fittings to increase the pipe diameter by flaring. It is usually completed by first heating and softening the pipe fitting, and then expanding the pipe through a mold.

[0003] Currently, there are many types of equipment for flaring plastic pipe fittings, and their structures are not entirely the same. However, most of them use electric heating clamps to heat the plastic pipe fittings and then expand them using cold molds at room temperature. This method has the following main drawbacks:

[0004] When plastic pipes are heated, they soften and tend to bend and sag. When inserted into the mold, the friction between the top of the inner wall of the pipe and the mold is greater than that between the bottom of the inner wall and the mold. This causes the top and bottom of the plastic pipe to shrink to different degrees when inserted into the mold due to the different friction forces, ultimately resulting in uneven circumferential material thickness and irregular ends of the pipe. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a plastic pipe fitting flaring device to solve the problems that existing plastic pipe fitting flaring devices easily cause uneven circumferential material thickness and irregular ends in the pipe fittings.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A plastic pipe fitting flaring device includes a fixed base, a lower clamp fixed on the fixed base via a vertical guide post, an upper clamp slidably connected to the vertical guide post and symmetrical to the lower clamp, a fixed platform fixed to the top of the vertical guide post, and a positioning push rod with the lower end of a piston rod connected to the upper clamp vertically mounted on the fixed platform.

[0008] The upper and lower clamps are both provided with clamping grooves that fit the pipe fittings. The upper and lower clamps are provided with flared grooves on one side of the clamping grooves that correspond to the pipe end position of the pipe fittings. The upper and lower clamps are also provided with transversely penetrating cooling channels.

[0009] The fixed base is slidably connected to a slide block located on one side of the upper clamp and the lower clamp. A flaring mold corresponding to the position of the flaring groove is fixedly installed on the side of the slide block. A transversely penetrating air duct is provided inside the flaring mold. The flaring mold includes an integral heating part and a flaring part. An electric heating wire is pre-embedded inside the heating part outside the air duct.

[0010] A ventilation slot is provided at the position of the slide corresponding to the air duct. A ventilation hole is provided at the position of the slide corresponding to the outer circumference of the flaring mold. A horizontal guide post is fixed horizontally on the side of the slide away from the flaring mold. A cooling fan corresponding to the ventilation slot is installed on the horizontal guide post through a mounting bracket. A fixing bracket fixed on a fixed base is slidably sleeved on the horizontal guide post. A flaring push rod with the front end of the piston rod connected to the mounting bracket is horizontally installed on the side of the fixing bracket away from the flaring mold.

[0011] Preferably, there are four vertical guide pillars, which are symmetrically arranged front to back and left to right on the upper and lower clamps, and the positioning push rod is located at the top center of the upper clamp.

[0012] Preferably, the cooling channels inside the upper and lower clamps are adapted to the inner wall shape of the clamping groove and the flared groove.

[0013] Preferably, a slider is fixed to the bottom of the slide block, and a groove is provided on the upper surface of the fixed base to slide and connect with the slider.

[0014] Preferably, the heating part and the flared part are adapted to the shape and size of the clamping groove and the flared groove, respectively.

[0015] Preferably, a wind-gathering shroud is fixed on one side of the slide corresponding to the cooling fan, and the ventilation hole is located inside the wind-gathering shroud.

[0016] Preferably, there are four horizontal guide posts, which are symmetrically arranged vertically and horizontally on the side of the slide block.

[0017] Preferably, the flared push rod is installed on the lower side of the fixing frame.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention uses an upper and lower clamp with a cooling function to fix plastic pipe fittings at room temperature. The upper and lower clamps are fixed by clamping grooves near the end of the pipe fitting. The end of the pipe fitting is heated by the heating part of the flaring mold, and the pipe is expanded by the flaring part of the flaring mold. The flaring grooves in the upper and lower clamps corresponding to the pipe fitting ends are used to position the flared pipe fitting. This provides support and positioning for the softened pipe fitting, preventing it from bending and sagging. The design of the flaring grooves also ensures that the thickness of the pipe fitting is uniform after flaring, thus improving product quality and solving the problem that existing plastic pipe fitting flaring equipment easily causes uneven circumferential material thickness and irregular ends of the pipe fitting.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a plastic pipe fitting processing and flaring device, including a fixed base 1, a lower clamp 3 fixed on the fixed base 1 by a vertical guide post 2, an upper clamp 4 slidably connected to the vertical guide post 2 and symmetrically arranged with respect to the lower clamp 3, four vertical guide posts 2 and symmetrically arranged front and back and left and right on the upper clamp 4 and the lower clamp 3, a fixed platform 5 fixed on the top of the vertical guide post 2, a positioning push rod 6 vertically installed on the fixed platform 5 with the lower end of the piston rod connected to the upper clamp 4, and the positioning push rod 6 is located at the top center of the upper clamp 4.

[0027] Both the upper clamp 4 and the lower clamp 3 have a clamping groove 8 inside that matches the pipe fitting 7. The upper clamp 4 and the lower clamp 3 have a flared groove 9 on one side of the clamping groove 8 that corresponds to the pipe end position of the pipe fitting 7. The upper clamp 4 and the lower clamp 3 also have a transversely penetrating cooling channel 10 inside. The cooling channel 10 inside the upper clamp 4 and the lower clamp 3 is adapted to the inner wall shape of the clamping groove 8 and the flared groove 9.

[0028] A slide block 11 is slidably connected to the fixed base 1 on one side of the upper clamp 4 and the lower clamp 3. A slider 24 is fixed at the bottom of the slide block 11. A slide groove 25 is provided on the upper surface of the fixed base 1 to slide and connect with the slider 24. A flaring mold 12 corresponding to the position of the flaring groove 9 is fixedly installed on the side of the slide block 11. A transverse air duct 13 is provided inside the flaring mold 12. The flaring mold 12 includes a heating part 14 and a flaring part 15 with an integral structure. The heating part 14 and the flaring part 15 are adapted to the shape and size of the clamping groove 8 and the flaring groove 9, respectively. An electric heating wire 16 is pre-embedded inside the heating part 14 outside the air duct 13.

[0029] A ventilation slot 17 is provided at the position of the slide block 11 corresponding to the air duct 13. A ventilation hole 18 is provided at the position of the slide block 11 corresponding to the outer circumference of the flaring mold 12. A wind concentrator 26 is fixed on the side of the slide block 11 corresponding to the cooling fan 21. The ventilation hole 18 is located inside the wind concentrator 26. A horizontal guide post 19 is horizontally fixed on the side of the slide block 11 away from the flaring mold 12. There are four horizontal guide posts 19, which are symmetrically arranged vertically and horizontally on the side of the slide block 11.

[0030] A cooling fan 21 corresponding to the ventilation slot 17 is mounted on the horizontal guide post 19 via the mounting bracket 20. A fixed bracket 22 fixed on the fixed base 1 is slidably sleeved on the horizontal guide post 19.

The flaring push rod 23 is installed on the lower side of the fixed bracket 22.

[0031] Working principle:

[0032] The positioning push rod 6 pushes the upper clamp 4 downward, clamping and fixing the pipe fitting 7 with the lower clamp 3 through the internal clamping groove 8. The flaring push rod 23 pushes the slide 11 and the flaring mold 12 to the left. When the heating part 14 at the left end of the flaring mold 12 is inserted into the pipe fitting 7, the heating part 14 is heated by the electric heating wire 16 to soften the pipe fitting 7. After the electric heating wire 16 stops heating, the flaring push rod 23 continues to push the flaring mold 12 to the left to further insert it into the pipe fitting 7. The flaring part 15 of the flaring mold 12 expands the pipe fitting. Under the restriction of the flaring groove 9 of the upper clamp 4 and the lower clamp 3, the wall thickness of the pipe fitting 7 is consistent after flaring. At the same time, the cooling channels 10 of the upper clamp 4 and the lower clamp 3 deliver cooling water through connecting hoses, and the cooling fan 21 blows air towards the flaring mold 12 to cool and shape the pipe fitting 7. By preventing the pipe fitting 7 from bending and sagging and ensuring consistent wall thickness, the quality of the product can be improved.
