Description

Technical Field

[0001] This utility model relates to the field of bending device technology, and in particular to an HDPE same-layer drainage pipe bending machine. Background Technology

[0002] HDPE drainage pipes are a general term for thermoplastic round pipes made primarily of high-density polyethylene resin using an extrusion molding process. They are designed for use without internal pressure. HDPE drainage pipes are a replacement for traditional steel pipes and polyvinyl chloride (PVC) drainage pipes. They are mainly used for drainage of rainwater, sewage, and farmland irrigation. They are widely used in drainage applications such as highways, railway subgrades, subway projects, landfills, tunnels, green belts, sports fields, and slope protection in areas with high water content, as well as underground irrigation and drainage systems in agriculture and horticulture.

[0003] During the laying process of HDPE same-layer drainage pipes, bending is required according to construction drawings and construction scenarios to ensure that the laying of HDPE same-layer drainage pipes is compatible with the main construction structure. However, due to the relatively high cost of existing bending machines, HDPE same-layer drainage pipe bending machines are generally not equipped on construction sites, which leads to limitations on the construction site. Therefore, on construction sites, the pipes are often heated first using a heating device and then bent manually. Manual bending is relatively labor-intensive, and errors due to manual operation affect the bending quality. In view of this, this application proposes an HDPE same-layer drainage pipe bending machine, which has a simple structure, is easy to use, has a low cost, and is easy to popularize on construction sites. Utility Model Content

[0004] To address the above situation and overcome the shortcomings of existing technologies, this utility model provides an HDPE in-layer drainage pipe bending machine. The technical solution it provides includes a base plate, characterized in that a drainage pipe guide and limiting assembly is arranged on the base plate, a mounting base is fixedly connected to the base plate, a first stepper motor is fixedly connected to the mounting base, one end of a driven rod is fixedly connected to the output shaft of the first stepper motor, the other end of the driven rod is fixedly connected to a vertical shaft, a bending roller is coaxially rotatably connected to the upper end of the vertical shaft, a bending groove is formed on the outer edge of the bending roller, two side plates arranged in a front-to-back configuration are fixedly connected to the mounting base, a worm gear is rotatably connected to the opposite ends of the two side plates, a second stepper motor for driving the worm gear is fixedly connected to the front side plate, a support plate is fixedly connected to the mounting base, a rotating shaft coaxially arranged with the output shaft of the first stepper motor is rotatably connected to the support plate, a worm wheel cooperating with the worm gear is coaxially fixedly connected to the rotating shaft, a positioning roller located above the worm wheel is coaxially fixedly connected to the rotating shaft, and a positioning groove cooperating with the bending groove is integrally formed on the right side of the outer edge of the positioning roller.

[0005] Preferably, the drain pipe guide and limiting assembly includes a support rod fixedly connected to the base plate, the upper end of the support rod having an arc-shaped groove, the base plate being fixedly connected to a connecting rod, the connecting rod being fixedly connected to a top plate, and the left end of the top plate having a top groove.

[0006] Preferably, the circumferential angle of the positioning groove is 180 degrees.

[0007] The beneficial effects of this utility model are: 1. In use, the HDPE drainage pipe is sequentially passed through the drainage pipe guide and limiting component, as well as the gap formed by the bending groove and the positioning groove, thereby completing the restriction and positioning of the HDPE drainage pipe. Then, the first stepper motor is started and rotated clockwise by a set angle, and the driven rod will rotate accordingly by a corresponding circumferential angle. At the same time, the vertical shaft on the driven rod and the bending roller will also rotate around the output shaft of the first stepper motor by a corresponding angle. During the rotation of the first stepper motor, the bending roller will also act on the HDPE drainage pipe, and the bending operation of the HDPE drainage pipe is completed under the restriction of the positioning groove. The operation is simple, the structure is simple, the use is convenient, the cost is low, and it is easy to popularize on construction sites.

[0008] 2. After bending is completed, the second stepper motor can be rotated to the set stroke, and the positioning roller can be rotated 180 degrees clockwise through the cooperation of the worm and worm wheel, so that the positioning groove is disengaged from the HDPE drain pipe, and the bent HDPE drain pipe can be easily removed.

[0015] The following is in conjunction with the appendix Figure 1-5 The specific embodiments of this utility model will be described in further detail.

[0016] In the first embodiment, the technical solution is as follows: when using this application, the HDPE drainage pipe 23 is sequentially passed through the drainage pipe guide and limiting component above the base plate 1, as well as the gap formed by the bending groove 9 and the positioning groove 17, thereby completing the restriction and positioning of the HDPE drainage pipe 23. Then, the first step motor 4 is started and rotated clockwise by a set angle, and the driven rod 6 will rotate accordingly by a corresponding circumferential angle. At the same time, the vertical shaft 7 on the driven rod 6 and the bending roller 8 will also rotate around the output shaft 5 of the first step motor by a corresponding angle. During the rotation of the first step motor 4, the bending roller 8 will also act on the HDPE drainage pipe 23, and under the restriction of the HDPE drainage pipe 23 by the positioning groove 17, the bending operation of the HDPE drainage pipe 23 is completed. The operation is simple, the structure is simple, the use is convenient, the cost is low, and it is easy to popularize on the construction site. After bending is completed, the second stepper motor 12 can rotate the set stroke, and through the cooperation of the worm gear 11 and the worm wheel 15, the positioning roller 16 can be driven to rotate 180 degrees clockwise, thereby causing the positioning groove 17 to disengage from the HDPE drain pipe 23, so that the bent HDPE drain pipe 23 can be easily removed.

[0017] Furthermore, to facilitate bending, the bending portion of the HDPE drainage pipe 23 should be heated using an existing instantaneous pipe heater before the preparation work is completed. The instantaneous pipe heater is small in size and easy to carry. In actual operation, pipe laying personnel generally carry their own, so it can be said to be a basic tool. Therefore, this application will not describe it in detail.

[0018] Example 2: Based on Example 1, during the bending operation, the HDPE drainage pipe 23 is as shown in the attached drawings of the instruction manual. Figure 1As shown, the HDPE drain pipe 23 is placed in the groove 19 above the support rod 18, with one end passing through the channel formed by the positioning groove 17 and the bending groove 9, thus completing the placement and positioning of the HDPE drain pipe 23. A top plate 21 is provided above the connecting rod 20, and the top groove 22 on the top plate 21 fits with the outer edge of the HDPE drain pipe 23, further ensuring the stability of the HDPE drain pipe 23 and facilitating its bending. Although the HDPE drain pipe 23 itself has a certain degree of elasticity, the angle of the top groove 22 should not be too large in order to facilitate the removal of the HDPE drain pipe 23 after bending.

[0019] As described above, install the HDPE drainage pipe 23 as shown in the attached diagram of the instruction manual. Figure 1 After positioning, the first stepper motor 4 on the mounting base 3 is started and rotated clockwise by the set stroke. Its output shaft 5 will then drive the driven rod 6 to rotate by the corresponding angle. The vertical shaft 7 on the driven rod 6 and the bending roller 8 will also rotate by the same angle. Since the HDPE drain pipe 23 is inserted in the channel formed by the bending groove 9 and the positioning groove 17, the bending roller 8 will bend the HDPE drain pipe 23 through the bending groove 9 as the driven rod 6 rotates. With the limiting effect of the positioning groove 17, the bending operation of the HDPE drain pipe 23 can be perfectly completed. After bending is completed, starting the stepper motor to reverse the set angle can drive the relevant components to reset.

[0020] Furthermore, after bending, when the HDPE drain pipe 23 is too long to be easily pulled out, a positioning groove 17 is set to be a 180-degree semicircle to facilitate its removal. When removing the bent HDPE drain pipe 23, the second stepper motor 12 of the side plate 10 is started to rotate by a set stroke. The second motor then drives the worm gear 11 to rotate by the corresponding stroke. The worm gear 11, through its cooperation with the worm wheel 15, drives the rotating shaft 14 on the support plate 13 to rotate 180 degrees. Consequently, the positioning roller 16 also rotates 180 degrees. When the positioning roller 16 rotates 180 degrees, the positioning groove 17 rotates by the same angle, causing the positioning groove 17 to move away from the HDPE drain pipe 23, i.e., the positioning groove 17 disengages from the HDPE drain pipe 23. At this point, the HDPE drain pipe 23 can be easily removed upwards. After removing the HDPE drain pipe 23, the second motor can be started again to rotate by a set stroke, causing the positioning roller 16 and the positioning groove 17 to rotate 180 degrees and reset. Because the worm gear 15 and worm 11 have a self-locking mechanism, the positioning roller 16 is driven by the worm gear 15 and worm 11, which helps it maintain a stable position during use and ensures normal operation.
