Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0029] like Figure 1 As shown, a stainless steel pipe bending device according to one embodiment of the present invention includes a housing 1. A rotating shaft 2 is rotatably connected to one end face of the housing 1. The rotating shaft 2 passes through one end face of the housing 1. A motor is built into the housing 1, and the motor drives the rotating shaft 2 to rotate. This is common knowledge in the art and will not be described in detail here.

[0030] like Figure 4 As shown, the rotating shaft 2 includes a first rotating shaft 201, which extends from the upper end face of the housing 1 and is rotatably connected to the housing 1. The rotation of the first rotating shaft 201 is not affected by the upper end face of the housing 1. A support plate 202 is welded to the outer end face of the first rotating shaft 201. The support plate 202 does not contact the upper end face of the housing 1, and its rotation is not affected by the housing 1. A plurality of first limiting blocks 203 are welded to one side end face of the support plate 202. The plurality of first limiting blocks 203 are all welded together with the first rotating shaft 201 and rotate together with the first rotating shaft 201.

[0031] like Figure 2 and Figure 7 As shown, a first bending disc 3 is engaged with one end face of the rotating shaft 2. The first bending disc 3 includes a disc body 301. A plurality of first limiting grooves 304 matching the first limiting block 203 are opened on one end face of the disc body 301. The first limiting block 203 is engaged in the first limiting groove 304. The rotating shaft 2 drives the engaged first bending disc 3 to rotate together, thereby realizing the bending of the stainless steel pipe.

[0032] The upper end face of the first bending disc 3 is engaged with the second bending disc 6. The diameter of the second bending disc 6 is smaller than that of the first bending disc 3. The upper end face of the disc body 301 is fixedly connected with multiple second limiting blocks 302, which are the same as the first limiting block 203. Similar to the first bending disc 3, the lower end face of the second bending disc 6 is also provided with a first limiting groove 304. The second limiting blocks 302 on the upper end face of the disc body 301 are engaged in the first limiting groove 304 on the lower end face of the second bending disc 6. The rotation of the first bending disc 3 drives the second bending disc 6 to rotate together. Since the disc diameters of the first bending disc 3 and the second bending disc 6 are different, the same bending device can bend stainless steel pipes into arcs of different radii.

[0033] At the same time, similar to the first bending disc 3, multiple second limiting blocks 302 are also welded to the upper end face of the second bending disc 6. The second bending disc 6 can also be placed in the position of the first bending disc 3 to be used with a bending disc with a smaller diameter.

[0034] A first limiting component 4 is welded to one end face of the housing 1. The first limiting component 4 includes a first fixed bracket 401, which is welded to the upper end face of the housing 1. A sliding bracket 402 is slidably connected inside the first fixed bracket 401. The opposite end faces of the sliding bracket 402 are provided with first sliding grooves 403. The sliding bracket 402 is engaged with the first fixed bracket 401 through the first sliding grooves 403, so that the sliding bracket 402 remains stable during sliding. Multiple second rotating shafts 404 are welded inside the sliding bracket 402. Limiting rollers 405 are sleeved on the outside of the second rotating shafts 404. The limiting rollers 405 rotate around the second rotating shafts 404. The arc of the limiting rollers 405 matches the arc of the first bending disc 3. With their cooperation, they can hold the stainless steel pipe that needs to be bent. When bending, since the limiting rollers 405 can rotate, it does not affect the bending of the stainless steel pipe. Meanwhile, a fixing ring 303 is welded to the side of the disc body 301. When bending, one end of the stainless steel pipe is inserted into the fixing ring 303, and the limiting roller 405 cooperates with the disc body 301 to hold the stainless steel pipe that needs to be bent.

[0035] Similarly, a second limiting component 7 is slidably connected to one end face of the second fixed bracket 8. The second limiting component 7 cooperates with the second bending disc 6 to hold the stainless steel pipe that needs to be bent.

[0036] like Figure 5 As shown, the opposite end faces of the first fixed bracket 401 are respectively provided with a second shaft hole 407 and a first threaded hole 408. The second shaft hole 407 and the first threaded hole 408 have the same diameter, and their centers are on the same axis. A sliding rod 410 is inserted into the second shaft hole 407, and the sliding rod 410 passes through the first threaded hole 408. The outer end face of the sliding rod 410 is provided with external threads, and the sliding rod 410 is threadedly connected to the first threaded hole 408. Since the first fixed bracket 401 is fixed, the sliding rod 410 can extend and retract when it rotates inside the first threaded hole 408.

[0037] The sliding rod 410 is rotatably connected to the sliding bracket 402. A first shaft hole 406 is provided on one end face of the sliding bracket 402. The diameter of the first shaft hole 406 is smaller than the diameter of the second shaft hole 407. The sliding rod 410 passes through the first shaft hole 406. A washer 413 is sleeved on the outer wall of the protruding part. A first nut 412 is threaded on the outer wall of the washer 413. After tightening the first nut 412, the washer 413 and the sliding bracket 402 are not tightly fitted and remain separated. This allows the sliding rod 410 to rotate inside the first shaft hole 406 and also allows the sliding bracket 402 to slide simultaneously when the sliding rod 410 extends or retracts.

[0038] A rotating wheel 411 is sleeved on one end of the sliding rod 410. A third shaft hole 414 is opened on one end face of the sliding rod 410, and a fourth shaft hole 415 matching the third shaft hole 414 is opened on one end face of the rotating wheel 411. A first screw 416 is inserted into the wall of the fourth shaft hole 415, passing through the third shaft hole 414. A second nut 417 is threaded onto the first screw 416, which fixes the sliding rod 410 and the rotating wheel 411 together. Rotating the rotating wheel 411 can drive the sliding rod 410 to rotate, achieving a convenient and labor-saving effect. At the same time, when the rotating wheel 411 is not needed for a long time, the rotating wheel 411 can be removed by unscrewing the first screw 416, saving space.

[0039] like Figure 6As shown, a second sliding groove 801 is formed on one end face of the second fixed bracket 8, and a sliding block 701 matching the second sliding groove 801 is integrally formed on one end face of the second limiting component 7. The sliding block 701 slides within the groove wall of the second sliding groove 801, allowing the second limiting component 7 to be disassembled. Simultaneously, a pair of second pin holes 802 are formed on one end face of the second fixed bracket 8, and a pair of first pin holes 702 matching the second pin holes 802 are formed on one end face of the second limiting component 7. A pin 803 is inserted into the wall of the first pin hole 702, passing through the second pin hole 802, thus securing the second limiting component 7 onto the second fixed bracket 8, preventing it from sliding during operation. When the second limiting component 7 is not needed, the pin 803 can be pulled out, allowing the second limiting component 7 to slide off the second fixed bracket 8.

[0040] like Figure 8 As shown, a fixing cover plate 5 is fixedly connected to one side end face of the second limiting component 7. A pair of second threaded holes 409 are opened on one side end face of the second limiting component 7. A pair of third threaded holes 501 that match the second threaded holes 409 are opened on one side end face of the fixing cover plate 5. A second screw 502 is threadedly connected to the inner wall of the second threaded hole 409. The second screw 502 passes through the third threaded hole 501. Tightening the second screw 502 realizes the fixed connection between the fixing cover plate 5 and the second limiting component 7.

[0041] One end face of the fixed cover plate 5 abuts against one end face of the second bending disc 6. The fixed cover plate 5 is sleeved on the outer end face of the first rotating shaft 201. The bottom end face of the fixed cover plate 5 is provided with a second limiting groove 503 that matches the second limiting block 302. The second limiting groove 503 is a circular inner groove that can accommodate the second limiting block 302. Thus, the second limiting block 302 will not be affected by the fixed cover plate 5 when it rotates. Therefore, the fixed cover plate 5 holds the second bending disc 6 in place, preventing the second bending disc 6 from moving up and down, but not affecting the rotation of the second bending disc 6, thereby increasing the stability of the stainless steel pipe bending device.

[0042] like Figure 3 As shown, a storage groove 101 is provided on one end face of the box body 1. A fixing post 102 is welded on the groove wall of the storage groove 101. The diameter of the fixing post 102 is not greater than the inner diameter of the shaft hole of the first bending plate 3 and the second bending plate 6. In this way, the first bending plate 3 or the second bending plate 6 can be hung on the fixing post 102 after being replaced.

[0043] When using, such as Figure 1The diagram shows the first operating state of the stainless steel pipe bending device. When it is necessary to process the stainless steel pipe into two different radii of arc, the device can be adjusted to this state. The first bending disc 3, positioned below, cooperates with the first limiting component 4 to restrain the stainless steel pipe. The fixing ring 303 secures one end of the stainless steel pipe. The rotation of the rotating shaft 2 drives the first bending disc 3 to rotate, thus achieving the bending of the stainless steel pipe. Similarly, the second bending disc 6, cooperating with the second limiting component 7, can also bend the stainless steel pipe. In this case, the larger radius bending disc is used first to bend into a larger radius arc, and then the smaller radius bending disc is used to bend into a smaller radius arc. Thus, when bending the stainless steel pipe into arcs of different radii, only one bending device is needed, eliminating the need to change the bending device.

[0044] Figure 3 This is the second usage mode of the stainless steel pipe bending device. When it is not necessary to bend arcs of different radii, only one bending disc needs to be installed. Different radii of bending discs can be selected according to the different radii of the arcs being bent, eliminating the need to purchase different models of bending devices. Meanwhile, the bending discs not in use are hung on the storage slot 101, and the second limiting component 7 is placed on the inner wall of the storage slot 101. The unused rotating wheel 411 is removed and hung on the fixed column 102, thus saving space on the countertop of the cabinet 1 and providing workers with a larger working space.
