DETAILED DESCRIPTION

[0024] It should be pointed out that the following detailed description is exemplary, and is intended to provide further explanation of the present disclosure. Unless otherwise specified, all technical and scientific terms used in the present disclosure have the same meaning as generally understood by those skilled in the art to which the present disclosure belongs. In addition, it should be understood that when the terms "comprise" and / or "include" are used in the present disclosure, there are features, steps, operations, devices, components and / or their combinations.

[0025] In order to solve the technical problems mentioned in the background art, the present disclosure provides an interlaced roller indentation-free forming mechanism, as shown in Figure 1As shown, the forming mechanism comprises a mounting seat and a forming assembly, two ends of the forming assembly are respectively mounted on the mounting seats on both sides; the forming assembly comprises a first forming assembly 4 and a second forming assembly 6, the first forming assembly 4 comprises an upper main shaft 44 and a forming roller, the forming roller is mounted on the upper main shaft 44, the forming roller comprises an anti-indentation roller 41 and an upper roller 42, the anti-indentation roller 41 has a set length and is pressed on the web of the profile steel; the second forming assembly 6 is the same in structure as the first forming assembly 4 and is symmetrically arranged along the center plane of the forming mechanism. Specifically, the second forming assembly 6 comprises the same upper main shaft 44 and forming roller as the first forming assembly 4, the upper main shaft 44 of the second forming assembly 6 is the same height as the upper main shaft 44 of the first forming assembly 4, and the forming roller of the second forming assembly 6 and the forming roller of the first forming assembly 4 are oppositely staggered.

[0026] The forming rollers in the forming mechanism are located on two upper main shafts 44 and are staggered, compared with the prior art, even when forming a wide profile steel, the anti-indentation roller 41 can be pressed on a larger area of the web of the profile steel, avoiding the problem of indentation on the web of the profile steel, improving the forming quality of the profile steel, especially when producing wide profile steel, without affecting the appearance quality of the product.

[0027] The anti-indentation roller 41 has a cylindrical surface, which is pressed on the web of the profile steel, and the upper roller 42 has a conical surface, which is used to bend the wing plate of the profile steel. The cylindrical surface of the anti-indentation roller 41 contacts the web of the profile steel, which presses the web of the profile steel with uniform pressure to prevent indentation on the surface of the web during the forming process; the conical surface of the upper roller 42 gradually bends the wing plate of the profile steel, so that the wing plate forms a correct angle with the web. Through the shape design of the anti-indentation roller 41 and the upper roller 42, the pressure distribution of each part during the forming process can be effectively controlled, thereby avoiding the formation of indentation and improving the forming quality of the product, especially during the forming process of wide or thick profile steel.

[0028] As Figure 2As shown, the forming mechanism also includes a support assembly, which includes a first support assembly 8 and a second support assembly 7, the first support assembly 8 is located on the lower side of the first forming assembly 4, the first support assembly 8 includes a lower main shaft 81 and a lower roller 82, the lower roller 82 is aligned with the edge of the anti- indentation roller 41, the second support assembly 7 is the same structure as the first support assembly 8, and the relative position relationship between the second support assembly 7 and the second forming assembly 6 is the same as that between the first support assembly 8 and the first forming assembly 4. The first forming assembly 4 and the first support assembly 8 cooperate to form one side of the workpiece, and the second forming assembly 6 and the second support assembly 7 cooperate to form the other side of the workpiece. Through the cooperation of the support assembly, a firm and stable mechanical support is formed during the forming process, which avoids the unqualified workpiece caused by insufficient support or unstable structure during the forming process, thereby improving the stability of the entire production process and the precision of the product.

[0029] The lower main shaft 81 of the first support assembly 8 is a driving shaft, the end of the driving shaft is provided with a coupling 3, and the coupling 3 is connected with a power gear box. The driving shaft is the source of power of the entire forming mechanism, and the coupling 3 is connected with the power gear box, so that the power system is more direct and efficient in the whole mechanism, thereby improving the forming efficiency and avoiding power loss.

[0030] The forming roller is slidably installed on the upper main shaft 44 through the upper sliding sleeve 43, and the lower roller 82 is slidably installed on the lower main shaft 81 through the lower sliding sleeve 83. The design of the upper sliding sleeve 43 and the lower sliding sleeve 83 enables the forming roller and the lower roller 82 to be adjusted according to the width of the workpiece, thereby realizing indentation-free forming of workpieces of different specifications. The use of the sliding sleeve greatly improves the flexibility and adaptability of the forming mechanism, which can meet the forming needs of strip steels of different widths, reduces the adjustment time during type changing, and improves the production efficiency.

[0031] As shown in Figure 1 , Figure 3 The mounting seat includes a fixed seat 2 and a movable seat 1, both ends of the forming assembly are mounted on the fixed seat 2 and the movable seat 1 respectively, and a lifting seat 5 is mounted on the fixed seat 2 and the movable seat 1, the lifting seat 5 is slidably installed on the fixed seat 2 and the movable seat 1 in the vertical direction, and both ends of the upper main shaft 44 are mounted on the lifting seats 5 on both sides.

[0032] The lifting seat 5 adjusts the distance between the first forming assembly 4 and the second forming assembly 6, and the first support assembly 8 and the second support assembly 7 according to the thickness of the raw material strip steel. The upper main shaft 44 of the forming assembly can be adjusted in height with the thickness of the strip steel. Through the adjustment of the lifting seat 5, different specifications of workpieces can be flexibly adapted to ensure that each part in the forming process can obtain the most suitable pressure, thereby improving the forming quality.

[0033] As Figure 3 shown, the lifting seat 5 includes a middle frame and a baffle, the baffle is located on both sides of the middle frame, the width of the baffle along the horizontal direction is greater than the width of the middle frame, the edges of the two side baffles form clamping grooves, and the clamping grooves are clamped on the fixed seat 2 and the moving seat 1. By forming the clamping groove through the baffle, the clamping groove ensures the stable installation of the lifting seat 5, prevents the lifting seat 5 from being dislocated during use, and ensures the accuracy of the equipment.

[0034] The lifting seat 5 is also provided with a lifting rod, the lower end of the lifting rod is connected with the middle frame, and the upper end of the lifting rod is installed on the fixed seat 2 or the moving seat 1.

[0035] The design of the lifting rod enables the lifting seat 5 to stably lift on the fixed seat 2 or the moving seat 1, so as to adjust the height of the forming roller, and the whole adjustment process is more stable and accurate.

[0036] In summary, the embodiment provides an interleaved roller no-indentation forming mechanism to solve the indentation problem and low change efficiency in the prior art. The mechanism can quickly adjust the distance between the upper and lower rollers 82 when the workpiece specifications change, and can realize no-indentation forming. This design not only improves production efficiency, reduces cost, but also reduces the operation difficulty of workers, realizes no-indentation forming from small to large workpieces, and meets the market demand for high-quality photovoltaic brackets.
