Description
Technical Field
[0001] This utility model relates to the field of pipe processing technology, and in particular to a PE pipe processing device. Background Technology
[0002] In actual production, pipes are continuous long tubular structures that need to be cut into pipes of different lengths to become finished pipe products. If the pipe cannot be stably fixed during cutting, the cut will be poor. Therefore, in the prior art, utility model application CN201620324728.4 discloses a pipe cutting machine, including a housing with a pipe inlet and a pipe outlet. A cutting tool is placed between the pipe inlet and outlet, and clamping devices are provided at both the inlet and outlet. Each clamping device includes an upper half-ring and a lower half-ring, through which the pipe passes. The upper and lower half-rings are respectively connected to an upper driving component and a lower driving component for driving their opening and closing. While this structure solves the problem of easy damage to the pipe surface during clamping in existing pipe cutting machines to some extent... However, it still has the following problems when in use: it cannot fully wrap and clamp pipes of different diameters. When the pipe diameter is not equal to the diameter of the upper and lower half rings, the contact between the pipe and the upper and lower half rings is not tight, which can still easily cause damage to the surface of the pipe.
[0003] To solve the above problems, a new type of PE pipe processing device is needed. Summary of the Invention
[0004] The purpose of this invention is to provide a PE pipe processing device that can fully wrap and clamp pipes of different diameters, ensuring the stability of the pipes without causing surface damage.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0020] Example
[0021] like Figure 1-2As shown, a PE pipe processing device includes a cutting chamber 2 located on a workbench 1. Clamping assemblies are provided at both the inlet and outlet 3 of the cutting chamber 2. The clamping assemblies include a fixed half-ring 4 and a lifting half-ring 5. The fixed half-ring 4 is fixedly connected to the side wall of the cutting chamber 2, and the inner diameter of the fixed half-ring 4 is equal to the diameter of the outlet 3 and is concentrically positioned with the outlet 3. The lifting half-ring 5 is mirror-symmetrically positioned above the fixed half-ring 4 and is connected to a lifting drive assembly 6. The lifting drive assembly 6 is used to drive the lifting half-ring 5 to rise and fall, thereby achieving connection and separation from the fixed half-ring 4. The lifting drive assembly 6 may include a mounting plate 61, which is fixedly connected to the cutting chamber 2. A cylinder 62 is provided on the mounting plate 61, and the telescopic rod 153 of the cylinder 62 passes through the mounting plate 61 and is fixedly connected to the lifting half-ring 5.
[0022] Both the fixed half-ring 4 and the lifting half-ring 5 are detachably connected to the adjusting half-ring 7 on opposite sides, with a material channel between the two adjusting half-rings 7. The side of the adjusting half-ring 7 away from its central axis fits against either the fixed half-ring 4 or the lifting half-ring 5, and a slot is provided on this side. This slot corresponds to a first fixing member 8 on either the fixed half-ring 4 or the lifting half-ring 5, and the slot contains an internal thread that matches the external thread structure on the first fixing member 8. The first fixing member 8 can be a bolt, which enables a detachable fixed connection between the adjusting half-ring 7 and the fixed half-ring 4, or between the adjusting half-ring 7 and the lifting half-ring 5.
[0023] The workbench 1 is equipped with two support rods 9, which are fixedly connected to the first connecting ears on both sides of the fixed half-ring 4. The support rods 9 can increase the stability of the fixed half-ring 4 on the side wall of the cutting chamber 2. The second connecting ears on both sides of the lifting half-ring 5 are equipped with guide holes that are adapted to the structure of the support rods 9. The support rods 9 can guide the lifting half-ring 5, thereby increasing the stability of the lifting half-ring 5.
[0024] The workbench 1 is equipped with a conveying support 10 adjacent to the discharge port 3. The horizontal bar 11 of the conveying support 10 has V-shaped bar groups 12 evenly distributed along the material conveying direction. Each V-shaped bar group 12 includes a first support rod 121 and a second support rod 122 rotatably connected to the horizontal bar 11. The end of each first support rod 121 is connected to a first connecting rod 13, and the end of each second support rod 122 is connected to a second connecting rod 14. The first connecting rod 13 and the second connecting rod 14 are respectively connected to an adjusting support assembly 15. The adjusting support assembly 15 can adjust the position of the first connecting rod 13 and the second connecting rod 14 and provide support for them. After adjusting the position of the first connecting rod 13 and the second connecting rod 14, the angle between the first support rod 121 and the second support rod 122 can be changed, thereby enabling the V-shaped bar group 12 to convey pipes of different diameters. This prevents the pipes from bouncing due to height differences when moving from the discharge port 3 to the conveying support 10, improving the stability of the pipes on the conveying frame.
[0025] The adjusting support assembly 15 includes a lead screw 151, a guide rod 152, and a telescopic rod 153. Both the lead screw 151 and the guide rod 152 are vertically fixed on the worktable 1. A driven gear 154 is provided at the bottom end of the lead screw 151, meshing with a driving gear 155. The driving gear 155 is fixedly connected to the output shaft of a motor, enabling the motor to drive the lead screw 151 to rotate. A lifting nut is provided on the lead screw 151, with a horizontal insert rod 156 and a third connecting lug 157 on each side. The third connecting lug 157 is slidably connected to the guide rod 152 through a through hole. The horizontal insert rod 156 and the third connecting lug 157 can move up and down as the lead screw 151 rotates. The horizontal insert rod 156 has evenly distributed fixing holes along its length, and it connects to the telescopic rod 153. The motor is a self-locking motor with a power-off function to prevent the lead screw 151 from rotating and affecting the height of the telescopic rod 153 after the motor is powered off. The telescopic rod 153 includes a horizontal section and a vertical section. The horizontal section has a slot adapted to the structure of the horizontal insertion rod 156. A second fixing member 158, communicating with the slot, is located at one end of the horizontal section near the horizontal insertion rod 156. The second fixing member 158 is adapted to the structure of the fixing hole. The end of the horizontal section near the horizontal rod 11 is fixedly connected to the vertical section. A curved support plate 159 is located at the top of the vertical section. Fixing the fixing member in the fixing holes at different positions can change the distance between the telescopic rod 153 and the horizontal rod 11. The curved support plate 159 is adapted to the structure of the first connecting rod 13 or the second connecting rod 14. The curved structure of the curved support plate 159 increases its contact area with the first connecting rod 13 and the second connecting rod 14, thereby increasing the stability of the first connecting rod 13 and the second connecting rod 14.
[0026] Before use, select the adjusting half-ring 7 with different inner diameter sizes according to the pipe diameter. Then, use the first fixing part 8 to install the two adjusting half-rings 7 onto the fixed half-ring 4 and the lifting half-ring 5 respectively. Then, according to the pipe diameter, use the adjusting support assembly 15 to adjust the angle between the first support rod 121 and the second support rod 122 in the V-shaped rod group 12 so that after the pipe is moved out of the outlet 3, the bottom sides of the pipe can contact the first support rod 121 and the second support rod 122, completing the smooth transition of the pipe from the outlet 3 to the conveying bracket 10. During use, after the pipe is moved to the cutting chamber 2, the lifting half-ring 5 at the inlet and outlet 3 lowers along with an adjusting half-ring 7 on it, so that the two adjusting half-rings 7 come into contact and fully wrap and clamp the pipe, ensuring the stability of the pipe without causing surface damage. After the cutting component in the cutting chamber 2 completes one cut, the pipe can move forward under the push of the pushing device. When moving forward, the pipe behind pushes the cut pipe onto the conveying support 10, completing the smooth transition of the pipe from the outlet 3 to the conveying support 10.
[0027] Therefore, the PE pipe processing device of the present invention, which adopts the above structure, can fully wrap and clamp pipes of different diameters, ensuring the stability of the pipes without causing surface damage.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
