Abstract
Description
Technical Field
[0001] This utility model relates to the field of flaring machine technology, and in particular to a positioning and guiding structure for a plastic composite pipe flaring machine. Background Technology
[0002] The positioning and guiding structure of a plastic composite pipe flaring machine typically consists of multiple components designed to ensure accurate positioning and smooth expansion of the pipe during the flaring process. It ensures precise alignment and stable movement of the pipe during the flaring process, significantly improving the coaxiality and dimensional accuracy of the flaring while reducing the risk of pipe deformation.
[0003] Patent document CN213134774U discloses a radial extrusion tube end flaring machine, including a hydraulic cylinder, a piston rod, and a flaring die. One end of the piston rod is mounted on the hydraulic cylinder, and the end of the piston rod away from the hydraulic cylinder is connected to a polygonal wedge. Driven by the hydraulic cylinder, the piston rod pushes the polygonal wedge to move axially. The flaring die is mounted on the outside of the polygonal wedge and is also provided with a die guide groove. Driven by the polygonal wedge, the flaring die moves radially along the die guide groove, and its outer diameter increases as it moves radially along the guide groove. This utility model provides a radial extrusion tube end flaring machine that uses a radial extrusion tube end flaring method. The flaring portion of the tube does not generate heat, does not change the material structure, has a fast flaring speed, low power consumption, saves energy, and the tube end flaring size range can be easily automated.
[0004] However, the positioning and guiding structure of existing plastic composite pipe flaring machines is difficult to quickly and synchronously adjust the support height when changing to different pipe diameters. This results in the pipe end and the mold not being accurately aligned, which can easily lead to flaring deviation or uneven force due to height misalignment, affecting the consistency of flaring dimensions and sealing performance.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a positioning and guiding structure for a plastic composite pipe flaring machine, comprising a support platform, a base slidably connected to the bottom of the support platform, a rotating shaft rotatably connected inside the base, two sets of pushing components sleeved on the surface of the rotating shaft, a positioning plate fixedly connected to the top of the support platform, two sets of sliding blocks slidably connected inside the positioning plate, an adjusting component fixedly connected to one end of each sliding block, the pushing component comprising a rotating rod sleeved on the surface of the rotating shaft, a transmission rod rotatably connected to the top of the rotating rod, and a movable bolt rotatably connected to the top of the transmission rod; the adjusting component comprising a support spring fixedly connected to one end of each sliding block, a threaded sleeve fixedly connected to one end of the support spring, and a threaded rod threadedly connected inside the threaded sleeve.
[0009] As a further embodiment of this utility model, a crossbar is fixedly connected to the top of the movable bolt, and a push rod is fixedly connected to the top surface of both ends of the crossbar. The push rod serves to push the support platform.
[0010] As a further embodiment of this utility model, a partition is slidably connected to the surface of the push rod, and the partition is fixedly connected to the inner wall of the base. The partition helps to maintain stable lifting and lowering.
[0011] As a further embodiment of this utility model, two sets of hydraulic rods are fixedly connected to one side of the base, and a fixing seat is sleeved on the surface of the hydraulic rod. The fixing seat serves to support the hydraulic rod.
[0012] As a further embodiment of this utility model, a drive motor is fixedly connected to one end of the rotating shaft, and two sets of slide rails are slidably connected to the bottom of the base. The slide rails facilitate the sliding of the base.

[0015] (III) Beneficial Effects
[0016] This utility model provides a positioning and guiding structure for a plastic composite pipe flaring machine, which has the following beneficial effects:
[0017] 1. The positioning and guiding structure of this plastic composite pipe flaring machine, through the setting of the push component, allows for height adjustment as needed during use. The drive motor is activated, causing the drive motor to rotate the rotating shaft, which in turn rotates the rotating rod. This causes the transmission rod to rotate on the rotating rod and the movable bolt, which in turn pushes the crossbar, causing the push rod to slide within the sliding hole on the partition plate. This, in turn, pushes the support platform to slide and rise within the base, achieving a stable adjustment of the flaring machine's height. When changing to different pipe diameters, the support height can be quickly and synchronously adjusted to ensure precise alignment between the pipe end and the mold, ensuring strict alignment between the pipe centerline and the flaring mold centerline. This avoids flaring misalignment or uneven force due to height misalignment, guaranteeing consistent flaring dimensions and sealing performance.
[0018] 2. The positioning and guiding structure of this plastic composite pipe flaring machine, through the adjustment of component settings, allows the hydraulic rod to push the base to move during use. When the extrusion die head contacts and extrudes the composite pipe, the extrusion generates pressure, causing the flaring machine body to drive the sliding block at the bottom to slide within the groove of the positioning plate. The sliding block then compresses the support spring, causing the support spring to deform under force and generate elastic force, which pushes the sliding block in the opposite direction. The spring deformation absorbs the instantaneous impact energy, preventing the pipe from rupturing due to a sudden increase in pressure. At the same time, the threaded sleeve rotates on the surface of the threaded rod, which can push the support spring to move its position. The pre-compression of the support spring can be precisely adjusted to meet the flaring requirements of pipes with different hardness. Attached Figure Description

A positioning plate 5 is fixedly connected to the top of the support platform 1, and two sets of sliding blocks 6 are slidably connected inside the positioning plate 5. One end of each sliding block 6 is fixedly connected to an adjustment... The entire assembly 7, by adjusting the settings of the assembly 7, utilizes the deformation of the spring to absorb the instantaneous impact energy, preventing the pipe from rupturing due to a sudden increase in pressure. At the same time, the threaded sleeve 702 rotates on the surface of the threaded rod 703, which can push the support spring 701 to move its position, allowing for precise adjustment of the pre-compression of the support spring 701 to adapt to the flaring requirements of pipes with different hardness.

[0028] Two sets of hydraulic rods 11 are fixedly connected to one side of the base 2. The surface of the hydraulic rods 11 is fitted with a fixed seat 12, which serves to support the hydraulic rods 11.
[0029] One end of the rotating shaft 3 is fixedly connected to a drive motor 13, and the bottom of the base 2 is slidably connected to two sets of slide rails 14. The slide rails 14 facilitate the sliding of the base 2.

A control console 19 is set on one side of the machine platform 17. The control console 19 facilitates adjustment and control.
[0032] In this invention, the working steps of the device are as follows:
[0033] First step: When in use, start the drive motor 13 according to the height to be adjusted as needed, so that the drive motor 13 drives the rotating shaft 3 to rotate, and then the rotating shaft 3 drives the rotating rod 401 to rotate, so that the transmission rod 402 rotates on the rotating rod 401 and the movable bolt 403 respectively, and then the movable bolt 403 pushes the crossbar 8, so that the push rod 9 slides in the sliding hole on the partition plate 10, and pushes the support platform 1 to slide and rise and fall in the base 2;
[0034] The second step: When in use, the hydraulic rod 11 pushes the base 2 to move, and when the extrusion mold head 16 contacts the composite tube, the extrusion generates pressure, causing the flaring machine body 15 to drive the bottom sliding block 6 to slide in the groove of the positioning plate 5. Then the sliding block 6 squeezes the support spring 701, causing the support spring 701 to deform under force and generate elastic force, pushing the sliding block 6 in the opposite direction.
