[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 and Figure 2 As shown, a straight seam welded pipe forming device comprises a bottom plate 1, a support plate 2 is fixed on the upper end of the bottom plate 1, a support roller 21 is fixed on the upper end of the support plate 2, a reel is sleeved on the support roller 21, and the diameter of the reel is larger than the support roller 21, a clearance groove 22 is opened on the upper end of the support roller 21 along the generatrix direction, and the straight seam welding is performed at the clearance groove 22;

[0029] A baffle assembly 3 is provided on the support plate 2. Figure 3 As shown, the baffle assembly 3 includes a mounting plate 31 fixed on the support plate 2 and located above the support roller 21, and a plurality of baffles 33 capable of being raised and lowered are arranged on the mounting plate 31. The baffles 33 can be lowered and enter the clearance groove 22 to facilitate one of the overlapping edges on the reel to contact and limit the baffle 33, so as to facilitate the limiting of the weld;

[0030] In this embodiment, the baffle 33 is driven to descend by arranging a cylinder 32 on the mounting plate 31. Of course, in some embodiments, the baffle 33 can also be driven to rise and fall by arranging a linear driving component such as a telescopic rod or a hydraulic cylinder.

[0031] A pressure plate assembly 4 is provided on the support plate 2. Figure 4 As shown, the pressure plate assembly 4 includes two pressure plates 41 that can be raised and lowered, and the two pressure plates 41 can act on the two overlapping edges of the roll respectively and press it tightly on the support roller 21;

[0032] In this embodiment, the two pressing plates 41 are slidably connected to the support plate 2 in the vertical direction, and two first fixing plates 23 are provided on the support plate 2. A first screw rod 42 is rotatably connected to each of the two second fixing plates 23. The two first screw rods 42 respectively penetrate the two pressing plates 41 in the vertical direction. By providing two motors to drive the two first screw rods 42 to rotate respectively, the lifting and lowering movement of the pressing plates 41 can be controlled; and the first screw rod 42 has a self-locking property (the thread lead angle of the first screw rod 42 is less than the equivalent friction angle) to ensure the stable pressing force of the pressing plate 41 on the overlapping edge of the reel.

[0033] Of course, the method of driving the pressure plate 41 to rise and fall includes but is not limited to the first screw rod 42 and other structures in this embodiment. In some embodiments, two hydraulic cylinders can be set on the support plate 2 to drive the two pressure plates 41 to rise and fall respectively.

[0034] When in use, first control the baffle 33 to descend and enter the make way slot 22, manually control one of the overlapping edges of the reel to contact and align with the baffle 33, and then drive the corresponding pressure plate 41 above the overlapping edge to press it against the support roller 21; then control the baffle 33 to rise to the highest point, and manually control the other overlapping edge of the reel to align with the previously pressed overlapping edge, and then control the other pressure plate 41 to descend to press the overlapping edge, thereby achieving the alignment of the two overlapping edges of the reel and locating them in the make way slot 22, and finally use a welding gun to perform straight seam welding along the overlapping portion to achieve straight seam welding of the reel.

[0035] A welding assembly 5 is provided at the upper end of the bottom plate 1, and the welding assembly 5 can realize straight seam welding of the overlapped part of the roll; Figure 5 As shown, the welding assembly 5 includes a sliding frame 51 that can slide on the upper end of the bottom plate 1, and the sliding direction is the axial direction of the support roller 21. A welding gun 52 is arranged on the sliding frame 51 to achieve straight seam welding;

[0036] In this embodiment, two second fixed plates 54 are provided at the upper end of the base plate 1, and a second screw rod 53 is rotatably connected between the two second fixed plates 54. The second screw rod 53 penetrates the sliding frame 54 along the axial direction of the support roller 21 and is threadedly connected to the sliding frame 54. A motor is provided on one of the second fixed plates 54 to drive the second screw rod 53 to rotate, so that the sliding frame 51 can be driven to slide axially along the support roller 21; and the second screw rod 53 has self-locking properties, that is, the thread lead angle of the second screw rod 53 is smaller than the equivalent friction angle.

[0037] Of course, the method of driving the sliding frame 51 to slide includes but is not limited to the second screw rod 53 in this embodiment. In some embodiments, the sliding frame 54 can also be directly driven to slide by setting a linear driving component such as a telescopic rod on the bottom plate 1.

[0038] A push plate assembly 6 is provided on the bottom plate 1, and the push plate assembly 6 can push the welded reel away from the support roller 21 to improve the convenience of unloading;

[0039] like Figure 6 As shown, the push plate assembly 6 includes a push plate 61 that can slide axially on the bottom plate 1 along the support roller 21. The upper end of the push plate 61 is semicircular. The end surface of the reel can contact the upper end of the push plate 61, and the overlap of the reel does not contact the push plate 61, which can prevent the welding gun from welding the reel and the push plate 61 together.

[0040] In this embodiment, the push plate 61 is slidably connected to the bottom plate 1 in the axial direction of the support roller 21, a third fixed plate 62 is fixed to the upper end of the bottom plate 1, a third screw rod 63 is rotatably connected between the support plate 2 and the third fixed plate 62, the third screw rod 63 penetrates the push plate 61 and is threadedly connected thereto, and a motor is provided on the support plate 2 to drive the third screw rod 63 to rotate, so that the push plate 61 can be driven to slide;

[0041] In order to ensure that the push plate 61 remains stable after the position is adjusted, the third screw rod 63 needs to have a self-locking property, that is, the thread lead angle of the third screw rod 63 is smaller than the equivalent friction angle.

[0042] In some embodiments, the push plate 61 may be driven to slide by providing a linear driving component such as a telescopic rod.

[0043] Working principle:

[0044] By setting a support roller 21 on the support plate 2 to facilitate the support of the roll sleeve, setting a baffle assembly 3 on the support plate 2 to facilitate the alignment of one of the overlapping edges, and setting a pressure plate assembly 4 on the support plate 2 to press and fix the aligned overlapping edge on the support roller 21, the other overlapping edge can be aligned with the previously pressed overlapping edge as a reference, and can also be pressed and fixed under the action of the pressure plate assembly 4, so as to ensure that the two overlapping edges are aligned and fixed before straight seam welding to ensure the welding quality. By setting a push plate assembly 6, and setting a push plate 61 that can move axially along the support roller 21, it is convenient to push out the welded roll to improve the convenience of unloading.
