[0025] Please refer to Figure 1 and Figure 2 simultaneously. Now, the device for processing circular and rectangular special-shaped pipe fittings provided by the present utility model will be described. The device for processing circular and rectangular special-shaped pipe fittings includes a forming platform 1, forming ribs 2, a support frame 3, a pressing plate 4 and a driving part 5. The number of the forming ribs 2 is two. The two forming ribs 2 are fixedly installed on the forming platform 1, and the two forming ribs 2 are arranged at intervals to form a forming gap for pressing the steel plate; the support frame 3 is fixedly installed on the forming platform 1; the pressing plate 4 is located above the forming platform 1, and the position of the pressing plate 4 on the forming platform 1 has the freedom of adjustment in the vertical direction; the fixed end of the driving part 5 is fixedly installed on the support frame 3, the pressing plate 4 is installed on the driving end of the driving part 5, and is rotatably arranged on the driving end of the driving part 5. The axis of the rotating shaft of the pressing plate 4 on the driving end of the driving part 5 is arranged in the vertical direction.

[0026] Compared with the prior art, the device for processing circular and rectangular special-shaped pipe fittings provided by this embodiment is provided with a forming platform 1. On the top surface of the forming platform 1, two forming ribs 2 are fixedly installed by welding. The two forming ribs 2 form a forming gap for arc forming of the steel plate. A support frame 3 is fixedly installed on the forming platform 1, and a driving part 5 is fixedly installed on the support frame 3. The driving part 5 adopts a hydraulic cylinder. The driving end of the driving part 5 is arranged in the vertical direction, and the side edge at the top of the pressing plate 4 is installed at the driving end of the driving part 5. The driving part 5 can drive the pressing plate 4 to move downward and press the pressing plate 4 into shape. In this application, by rotatably arranging the pressing plate 4 at the driving end of the driving part 5, when pressing the steel plate, the position of the pressing plate 4 can be adjusted so that the length of the pressing plate 4 is arranged along the length of the forming gap. After the steel plate is pressed into shape, the pressing plate 4 and the steel plate can be rotated simultaneously so that the steel plate can be drawn out from one side edge of the pressing plate 4. The operation is simple and convenient for the on-site operators to unload the materials.

[0027] Specifically, in this embodiment, a mounting plate is fixedly installed by welding at the side of the top of the pressing plate 4. The mounting plate is connected to the driving end of the driving member 5 and is rotatably arranged on the driving end of the driving member 5. A support rib for strengthening the strength of the pressing plate 4 is also fixedly installed between the mounting plate and the pressing plate 4.

[0028] In some embodiments, the above-mentioned driving member 5 can adopt the structure as Figure 2 shown. Refer to Figure 2 , a fixed flange 51 is fixedly installed at the end of the driving end of the driving member 5. The fixed flange 51 is fixedly connected to a rotating disk 6. A rotating sleeve 7 is fixedly installed on the pressing plate 4. The rotating disk 6 is rotatably arranged inside the rotating sleeve 7. The driving member 5 is a hydraulic cylinder. When selecting the model of the hydraulic cylinder, a hydraulic cylinder with a flange driving rod is adopted. The flange at the end of the driving rod of the hydraulic cylinder is the fixed flange 51, and the fixed flange 51 is fixedly connected to the rotating disk 6 by bolts. And the rotating disk 6 is coaxially arranged with the driving end of the driving member 5. A rotating sleeve 7 is fixedly installed at the top of the pressing plate 4, and the rotating sleeve 7 is installed in the middle of the pressing plate 4. The rotating disk 6 is rotatably arranged inside the rotating sleeve 7, so that the angle of the pressing plate 4 can be adjusted during use, which is convenient for the operator to evacuate the arc-shaped steel plate formed by pressing from the forming platform 1.

[0029] In some embodiments, the above-mentioned rotating sleeve 7 can adopt the structure as Figure 2 shown. Refer to Figure 2 , a guiding hole for slidingly cooperating with the rotating disk 6 is arranged at the top of the rotating sleeve 7, and a limiting ring 8 for limiting the rotating disk 6 inside the guiding hole is detachably installed at the top of the rotating sleeve 7. A guiding hole for installing the rotating disk 6 is arranged at the top of the rotating sleeve 7, and the outer side wall of the rotating disk 6 is in sliding cooperation with the inner wall of the guiding hole. And a limiting ring 8 is fixedly installed at the top of the rotating sleeve 7 by bolts. When the limiting ring 8 and the rotating disk 6 are both installed inside the rotating sleeve 7, the bottom of the limiting ring 8 abuts against the top of the rotating disk 6 and is in sliding cooperation with the top of the rotating disk 6, so as to limit the rotating disk 6 inside the guiding hole.

[0030] Specifically, in this embodiment, a plurality of bolt through holes are arranged on the limiting ring 8, and threaded holes corresponding to the bolt through holes are arranged at the top of the rotating sleeve 7, so that the limiting ring 8 can be fixedly installed at the top of the rotating sleeve 7 by bolts.

[0031] In some embodiments, the above-mentioned limiting ring 8 can adopt the structure as Figure 2 shown. Refer to Figure 2, a limiting part 81 that protrudes from the end of the limiting ring 8 and is slidably engaged with the guiding hole is provided. When the limiting ring 8 is installed on the rotating sleeve 7, the limiting part 81 is used to limit the limiting ring 8 from sliding out of the guiding hole. At the bottom end of the limiting ring 8, a limiting part 81 also protrudes, and the outer side surface of the limiting part 81 is slidably engaged with the guiding hole, thereby positioning the installation position of the limiting ring 8. During use, the limiting part 81 on the limiting ring 8 can be slid into the rotating sleeve 7, enabling the limiting ring 8 to overlap on the top of the rotating sleeve 7, and rotating the limiting ring 8 to align the threaded hole on the limiting ring 8 with the threaded hole on the top of the rotating sleeve 7. Thus, it is convenient to fix the limiting ring 8 to the rotating sleeve 7.

[0032] Specifically, in this embodiment, when the limiting ring 8 is fixed to the rotating sleeve 7, the limiting part 81 and the guiding hole form a rotating space for the rotating disk 6 to rotate inside the guiding hole.

[0033] In some embodiments, the above-mentioned forming rib 2 can adopt a structure as Figure 1 shown. Refer to Figure 1 , the two forming ribs 2 are arranged at an angle. The two forming ribs 2 are arranged at an angle, so that a forming gap with a gradually increasing or decreasing width is formed between the two forming ribs 2. When pressing the steel plate, the forming radian of one end of the steel plate can be made smaller than that of the other end, so that after being welded together, a pipe fitting of a circular-rectangular special-shaped pipe can be formed.

[0034] In some embodiments, the above-mentioned forming platform 1 can adopt a structure as Figure 1 shown. Refer to Figure 1 , a baffle 9 for limiting the placement position of the steel plate is fixedly installed on the forming platform 1, and the baffle 9 is located outside the side with a smaller forming gap size. A baffle 9 is fixedly installed on the top of the forming platform 1. The baffle 9 is perpendicular to the top of the forming platform 1, and the baffle 9 is located outside the side with a smaller forming gap size. During use, one side edge of the steel plate can be abutted against the baffle 9, and the other side edge can be adjusted to align the pressing plate 4 with the marked position on the steel plate, thereby facilitating the positioning of the steel plate and improving the on-site processing efficiency.

[0035] In some embodiments, the above-mentioned baffle 9 can adopt a structure as Figure 1 shown. Refer to Figure 1 , two guiding plates 91 are fixedly installed on the side of the baffle 9 close to the forming gap, and the two guiding plates 91 form a guiding gap for guiding the downward movement of the pressing plate 4. Two guiding plates 91 are fixedly installed on the side wall of the baffle 9, and the two guiding plates 91 form a guiding gap for guiding the downward movement of the pressing plate 4. When the pressing plate 4 moves downward, it slides into the guiding gap and can move downward stably through the guiding of the guiding gap. This avoids the pressing plate 4 rotating around the axis of the driving end of the driving member 5 during the forming process. It improves the stability of the position of the pressing plate 4 during the forming process.

[0036] Preferably, in this embodiment, when placing the iron plate on the forming platform 1, one side of the iron plate can be abutted against the side of the guide plate 91 away from the baffle 9.

[0037] In some embodiments, the above-mentioned support frame 3 can be adopted as Figure 1 the structure shown. Refer to Figure 1 , the support frame 3 includes a cross beam 11 and a connecting plate 12. The number of cross beams 11 is two, and the two cross beams 11 are fixedly installed above the forming platform 1, and the two cross beams 11 are arranged in parallel at intervals; the connecting plate 12 is fixedly installed between the two cross beams 11, and the driving member 5 is fixedly installed on the connecting plate 12. Columns are fixedly installed on the forming platform 1, columns are provided at both ends of the cross beam 11, and both ends of the cross beam 11 are fixedly installed on the columns. The cross beam 11 is processed from an I-beam, and the connecting plate 12 is fixedly installed at the bottom of the upper flange of the I-beam by bolts. An installation position for installing the driving member 5 is provided in the middle of the connecting plate 12, and the driving end of the driving member 5 penetrates through the connecting plate 12 and extends downward. The structure is simple, which is convenient for the production and processing of the whole device.
