Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipe fitting processing, in particular to a single-head pipe bender for pipe fitting processing. Background Art

[0002] During the processing of plastic pipe fittings, bending is a common process that allows the pipe fittings to change direction or form specific angles according to design requirements, so as to adapt to complex pipeline system layouts. This process not only improves the flexibility and practicality of the pipeline system, but also enables the pipeline system to better adapt to various environments and application scenarios. For example, in the fields of building water supply and drainage systems, industrial pipeline systems, household water pipe systems, etc., the bending process of plastic pipe fittings is an essential step, because it can meet the requirements of different angles and paths, ensuring the effective operation and aesthetic layout of the pipeline system. Therefore, pipe bending equipment is needed to bend plastic pipe fittings.

[0003] The patent with the patent announcement number CN219881001U discloses a pipe bender with a heating function. Although the pipe bender with a heating function can heat the plastic pipe when bending, so that the plastic pipe becomes soft and is more conducive to bending, and the plastic pipe is not easy to rebound and deform after bending, thus avoiding repeated bending and increasing work efficiency, the device cannot press and fix the pipe fittings when bending the pipe fittings. When the pipe fittings are not effectively pressed and fixed during the bending process, the pipe fittings may shift or twist under the action of the bending force, resulting in a reduction in bending accuracy, unable to meet the high-precision processing requirements, and unable to bend the pipe fittings according to the required fixed distance. In some application scenarios, the pipe fittings need to be bent at specific intervals or angles. If the pipe bender cannot bend according to the required fixed distance or angle, then these specific processing requirements cannot be met. Summary of the Utility Model

[0013] The beneficial effect of adopting the above further solution is:

[0014] By sliding the sliding seat in the second sliding groove of the limiting plate, the user can accurately adjust the position of the top block. The design of the locking nut ensures that the top block can be firmly fixed at the required position after adjustment, preventing deviation during the processing. This accurate positioning mechanism ensures that the top rod can accurately insert into the plastic pipe to stably and accurately position the plastic pipe. The top rod is inserted into the plastic pipe to provide additional support and fixation for the plastic pipe. During the bending process, this internal support helps to reduce the shaking and deformation of the plastic pipe, thereby improving the stability of the processing. A stable processing environment helps to ensure that the processed pipe fittings meet the quality requirements and reduce the rejection rate.

[0015] Furthermore, the clamping assembly is provided with a fixed seat, and the clamping assembly is fixed to the base plate through the fixed seat, and a connecting plate is rotatably installed on the fixed seat, and a first handle is provided at one end of the connecting plate, and a third slide groove is opened at the end of the connecting plate away from the first handle, and a second pressure block is slidably installed in the third slide groove, and the second pressure block is fixed in the third slide groove by locking with a nut, and the clamping assembly presses and fixes the plastic tube through the third slide groove.

[0016] The beneficial effects of adopting the above further scheme are:

The user can adjust the position of the second clamping block in the third chute as needed to ensure effective compression and fixation of the plastic pipe. This design improves the versatility and adaptability of the equipment. The second clamping block is fixed in the third chute by a nut.

[0019] The beneficial effects of adopting the above further scheme are:

[0020] The design of the second handle allows the user to easily control the movable pressure wheel, thereby adjusting the pressure on the plastic tube as needed. This design improves the flexibility of operation, allowing users to easily complete bending tasks of different angles and curvatures. The combination of the movable pressure wheel and the fixed pressure wheel allows the plastic tube to pass through and be pressed stably, and the user can complete the bending process without additional tools or complicated operations, greatly improving work efficiency. By adjusting the rotation position of the movable pressure wheel on the side of the fixed pressure wheel, the user can accurately control the bending position and angle of the plastic tube. This precise control is particularly important for the manufacture of products that require precise size and shape. The stable pressing of the plastic tube between the movable pressure wheel and the fixed pressure wheel ensures the uniformity and consistency of the bending, reducing dimensional deviation or shape defects caused by improper operation.

This design ensures that the processed pipe fittings have a consistent bending angle and improves product quality. The limiting module provides a stable support and limiting point for the bent pipe assembly. During the bending process, the limiting force received by the bent pipe assembly is uniform and predictable, which helps to reduce processing errors caused by excessive rotation or unstable rotation. Therefore, this design improves the stability of processing.

[0024] The utility model provides a single-head pipe bender for pipe fitting processing, having the following beneficial effects:

[0037] Embodiment 1

[0038] A single-head pipe bender for pipe fitting processing, please refer to Figures 1 to 3 As shown, it includes a bottom plate 8. An electric heating block 5 is installed on the bottom plate 8. An elbow pipe assembly 7 is installed on one side of the electric heating block 5 on the bottom plate 8. The elbow pipe assembly 7 is provided with a second handle 701, and a fixed pressure wheel 703 is installed on the fixed shaft of the second handle 701 and the bottom plate 8. A movable pressure wheel 702 is rotatably installed on one side of the second handle 701 and located at the fixed pressure wheel 703. The plastic pipe 2 passes through between the movable pressure wheel 702 and the fixed pressure wheel 703. The plastic pipe 2 is pressed against the fixed pressure wheel 703 by the movable pressure wheel 702, so that the plastic pipe 2 is bent along the fixed pressure wheel 703. The design of the second handle 701 enables the user to easily control the movable pressure wheel 702, thereby adjusting the pressure on the plastic pipe 2 as needed. This design improves the flexibility of operation, enabling the user to easily complete bending tasks with different angles and curvatures. The combination of the movable pressure wheel 702 and the fixed pressure wheel 703 enables the plastic pipe 2 to pass through stably and be pressed against it, and the user can complete the bending process without additional tools or complex operations, greatly improving the work efficiency.

[0039] By adjusting the rotation position of the movable pressing wheel 702 on the side of the fixed pressing wheel 703, the user can accurately control the bending position and angle of the plastic tube 2. This precise control is particularly important for the manufacture of products that require precise size and shape. The stable pressing of the plastic tube 2 between the movable pressing wheel 702 and the fixed pressing wheel 703 ensures the uniformity and consistency of the bending, reducing the size deviation or shape defect caused by improper operation.

[0040] A limit module 1 is provided on one side of the bottom plate 8 at the bending pipe assembly 7. The limit module 1 is provided with a first pressing block 102 and a blocking block 103. A first sliding groove 101 is provided in the blocking block 103. The first pressing block 102 is located in the first sliding groove 101. The blocking block 103 is locked and fixed on the bottom plate 8 by the first pressing block 102. The bending angle of the bending pipe assembly 7 is limited by the blocking block 103. By adjusting the position of the first pressing block 102 in the first sliding groove 101, the user can accurately control the rotation range of the bending pipe assembly 7, thereby realizing accurate control of the bending angle of the plastic pipe 2. This design ensures that the processed pipe fittings have a consistent bending angle, thereby improving product quality.

[0041] The limiting module 1 provides a stable support and limiting point for the bending tube assembly 7. During the bending process, the limiting force on the bending tube assembly 7 is uniform and predictable, which helps to reduce the processing error caused by excessive rotation or unstable rotation. Therefore, this design improves the stability of the processing.

[0042] Example 2

[0043] In order to heat and soften the plastic tube 2 and fix the plastic tube 2 when it is bent, for example, Figures 1 to 3 As shown, it also includes: a protective plate 501 and an upper pressure plate 502 are fixed to the outside of the electric heating block 5, the electric heating block 5 is fixed to the bottom plate 8 by the upper pressure plate 502 and bolts, and the protective plate 501 is fixed to one side of the electric heating block 5 by bolts, and a positioning groove 503 is opened on the electric heating block 5, the plastic tube 2 is limited and placed on the electric heating block 5 by the positioning groove 503, and the plastic tube 2 is heated and softened by the electric heating block 5.

[0044] On one side of the bottom plate 8, a limiting plate 4 is provided. A second sliding groove 401 is formed on the limiting plate 4, and a scale marking 402 is provided at the position of the second sliding groove 401 on the limiting plate 4. The top block 3 is positioned through the scale marking 402. The existence of the scale marking 402 provides a precise reference point for the top block 3, enabling the user to accurately adjust the position of the top block 3, so as to ensure that the plastic pipe 2 can be bent at a predetermined angle and position during the bending process. This precise positioning can reduce errors during the processing, improving the accuracy and consistency of the product. The design of the scale marking 402 enables the user to quickly and accurately complete the positioning of the top block 3 with the naked eye without relying on complex measuring tools or equipment. This not only simplifies the operation process but also improves work efficiency. The user can directly find the corresponding positioning point through the scale marking 402 according to the processing requirements and quickly complete the setting.

[0045] The limiting plate 4 is slidably installed with a top block 3 through the second sliding groove 401. The top block 3 is provided with a sliding seat 303. The sliding seat 303 is locked and fixed in the second sliding groove 401 of the limiting plate 4 through a locking nut 302. And a top rod 301 is provided on the top block 3. The top rod 301 is inserted into the plastic pipe 2 to position the plastic pipe 2. By sliding the sliding seat 303 in the second sliding groove 401 of the limiting plate 4, the user can accurately adjust the position of the top block 3. The design of the locking nut 302 ensures that the top block 3 can be firmly fixed at the required position after being adjusted in place, preventing it from shifting during the processing.

[0046] This precise positioning mechanism ensures that the top rod 301 can accurately insert into the plastic pipe 2 to stably and precisely position the plastic pipe 2. The top rod 301 is inserted into the plastic pipe 2, providing additional support and fixation for the plastic pipe 2. During the bending process, this internal support helps reduce the shaking and deformation of the plastic pipe 2, thereby improving the stability of the processing. A stable processing environment helps ensure that the processed pipe fittings meet the quality requirements and reduces the rejection rate.

[0047] The bottom plate 8 is located on one side of the electric heating block 5 and is provided with a clamping assembly 6. The clamping assembly 6 is provided with a fixing seat 605. The clamping assembly 6 is fixed on the bottom plate 8 through the fixing seat 605. A connecting plate 603 is rotatably installed on the fixing seat 605. A first handle 604 is provided at one end of the connecting plate 603. A third slide groove 602 is provided at one end of the connecting plate 603 away from the first handle 604. A second pressing block 601 is slidably installed in the third slide groove 602. The second pressing block 601 is fixed in the third slide groove 602 by a nut. The clamping assembly 6 presses and fixes the plastic tube 2 through the third slide groove 602. The clamping assembly 6 can flexibly adapt to plastic tubes 2 of different diameters and sizes through the second pressing block 601 slidably installed in the third slide groove 602. The user can adjust the position of the second pressing block 601 in the third slide groove 602 as needed to ensure effective pressing and fixing of the plastic tube 2. This design improves the versatility and adaptability of the equipment. The second pressing block 601 is fixed in the third sliding groove 602 by a nut, and this fastening method ensures that the pressing assembly 6 can stably fix the plastic pipe 2 during the processing. Accurate fixation helps to reduce the movement and deformation of the plastic pipe 2 during the bending process and improve the processing accuracy.

[0048] Working principle:

[0049] The heat block is fixed on the bottom plate 8 and is secured by the upper pressing plate 502 and bolts. When the electric heat block 5 is powered, it generates heat to heat the plastic tube 2 placed in the positioning groove 503. The plastic tube 2 is limited on the electric heat block 5 by the positioning groove 503, ensuring that the plastic tube 2 can be evenly heated and softened to a degree suitable for bending.

[0050] The second slide groove 401 and the scale mark 402 on the limit plate 4 allow the top block 3 to slide and position as needed, and is fixed by the locking nut 302. The top rod 301 is inserted into the plastic tube 2 to provide additional support and positioning to ensure stability during the bending process. The clamping assembly 6 is installed on the bottom plate 8 through the fixing seat 605. The user can adjust the connecting plate 603 by rotating the first handle 604 so that the second clamping block 601 can be tightly pressed on the plastic tube 2 to fix it and prevent it from moving or deforming during the bending process.

[0051] The elbow pipe assembly 7 includes a second handle 701, a fixed pressing wheel 703, and a movable pressing wheel 702. The plastic pipe 2 passes through between the movable pressing wheel 702 and the fixed pressing wheel 703. By operating the second handle 701, the user makes the movable pressing wheel 702 approach the fixed pressing wheel 703, thereby pressing the plastic pipe 2 onto the fixed pressing wheel 703. The first pressing block 102 in the limit module 1 can be adjusted in position within the first sliding groove 101 of the blocking block 103. By adjusting the position of the first pressing block 102, the rotation angle of the elbow pipe assembly 7 can be limited, thereby precisely controlling the bending angle of the plastic pipe 2. After the plastic pipe 2 is heated and softened and fixed, the user can rotate the elbow pipe assembly 7 to bend the plastic pipe 2 along the contour of the fixed pressing wheel 703. Since the plastic pipe 2 has been softened and is fixed by the pressing assembly 6, it can smoothly complete the bending process without breaking or deforming.
