Description

Technical Field

[0001] This invention relates to the field of purlin processing equipment, and more particularly to a steel structure C-shaped purlin bending machine. Background Technology

[0002] Purlins, also known as purlins or purlins, are horizontal roof beams perpendicular to roof trusses or rafters, used to support rafters or roofing materials. Purlins are transversely bending (usually bi-directional bending) members and are generally designed as single-span simply supported purlins. Commonly used purlins include C-shaped purlins and L-shaped purlins. Purlins are required in the erection of various steel structure buildings.

[0003] In the construction of various steel structure buildings, purlins with different curvatures are often required depending on the design. Generally, a bending machine is used to bend the purlins.

[0004] Due to the special structure of C-shaped purlins, with the presence of flanges and rolled edges, different steel bending machines cannot meet the usage requirements. They are prone to large deformations when bending C-shaped purlins, affecting the structural strength of C-shaped purlins, resulting in poor bending quality. Furthermore, they cannot meet the needs of different types of bending, making them inconvenient to use. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the tendency for large deformation to occur during C-shaped purlin bending, which affects the structural strength of the C-shaped purlin, resulting in poor bending quality and inability to meet the needs of different types of bending, as well as inconvenience in use. Therefore, this invention proposes a steel structure C-shaped purlin bending machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A steel structure C-shaped purlin bending machine includes a frame, with a horizontal support plate at the upper end of the frame, and C-shaped purlins placed on the support plate;

[0008] The upper side of the frame is vertically rotatably equipped with two pressing wheels corresponding to the back side of the C-shaped purlin. The front side of the C-shaped purlin is also equipped with a feeding wheel and an inner limit wheel corresponding to the pressing wheels. The frame is equipped with a feeding motor for driving the feeding wheel.

[0009] Telescopic cylinders are horizontally fixedly installed on both sides of the C-shaped purlin above the frame. Rotating frames are fixedly installed on one side of the telescopic end of the telescopic cylinders. A curved wheel is vertically rotatably installed in the rotating frame corresponding to the back side of the C-shaped purlin. A support wheel corresponding to the groove on the front side of the C-shaped purlin is provided in the rotating frame on the other side.

[0010] Positioning sleeves are rotatably mounted on the rotating shafts on both sides of the support wheel, and the positioning sleeves are mounted on the rotating frame. Inner support wheels corresponding to the inner side of the rolled edge of the C-shaped purlin are rotatably mounted on the positioning sleeves.

[0011] Preferably, the support plate is provided with multiple limiting bolts that slide through it. The limiting bolts are all vertically fixed on the frame, and locking nuts are threaded to the upper and lower sides of the support plate corresponding to the limiting bolts.

[0012] Preferably, the inner limiting wheel is located between the feeding wheel and the support wheel, and the width of the inner limiting wheel matches the inner dimension of the C-shaped purlin's rolled edge.

[0013] Preferably, both of the two clamping wheels are provided with rotating seats on their downward sides, and a mounting plate is provided vertically on the rear side of the frame. Each rotating seat is connected by a horizontal threaded adjusting bolt, which passes through the mounting plate and is provided with a locking nut.

[0014] More preferably, multiple limiting rods are slidably provided through the two rotating seats, and the limiting rods are all horizontally fixedly installed on the mounting plate.

[0015] Preferably, the width of the curved wheel is greater than millimeters.

[0016] Preferably, the two positioning sleeves are also fixedly provided with adjustment plates. Each adjustment plate has a stud and a limiting slide rod vertically on opposite sides. The stud and the limiting slide rod pass through both sides of the rotating frame, and each stud is threaded with two adjusting nuts.

[0017] Preferably, both positioning sleeves are rotatably provided with pressure bushings on their outer sides, and the gap between the pressure bushings and the inner support wheel matches the thickness of the C-shaped purlin.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, the positions of the bending wheel and the support wheel are adjusted by the cooperation of two telescopic cylinders, which can effectively adapt to different types of bending requirements, such as bending only at the end and bending in the middle, thus ensuring the bending capacity of the bending machine and facilitating the use of bending.

[0020] 2. In this invention, the support wheel and the inner support wheel work together to provide support on the inner side of the C-shaped purlin and the inner side of its rolled edge, so as to ensure the stability of the C-shaped purlin's arc shape during bending and to ensure the quality of the bending.

[0021] 3. In this invention, by adjusting the inner support wheel, it can effectively adapt to different models of C-shaped purlins and provide support when bending, ensuring the bending ability of the C-shaped purlins and the applicability of the bending machine.

[0022] This invention is reasonably designed and has a compact structure, which effectively improves the bending capacity of the bending machine, ensures the bending quality, avoids the deformation of the rolled edge when bending C-shaped purlins, and can meet different bending requirements and different models of C-shaped purlins. It has a wide range of applications and is easy to use. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Example 1

[0033] Reference Figure 1-4 A steel structure C-shaped purlin bending machine includes a frame 1, with a horizontal support plate 2 at the upper end of the frame 1, and a C-shaped purlin a placed on the support plate 2. The C-shaped purlin a is placed laterally to facilitate bending.

[0034] Two clamping rollers 5 are vertically rotatably mounted on one side of the upper part of the frame 1, corresponding to the back side of the C-shaped purlin a. A feeding roller 3 and an inner limit roller 4 are also provided on the front side of the C-shaped purlin a, corresponding to the clamping rollers 5. A feeding motor 31 is provided inside the frame 1 to drive the feeding rollers 3. Through the cooperation of the feeding rollers 3 and the clamping rollers 5, the feeding rollers 3 are pressed against the inner wall of the groove on the front side of the C-shaped purlin a, and the C-shaped purlin a is clamped and fed, so as to ensure the feeding effect of the C-shaped purlin a.

[0035] Telescopic cylinders 6 are horizontally fixedly installed on both sides of the C-shaped purlin a above the frame 1. Rotating frames 61 are fixedly installed on one side of each telescopic cylinder 6, near each other. A bending wheel 7 is vertically rotatably installed inside the rotating frame 61 corresponding to the back side of the C-shaped purlin a. A support wheel 71 corresponding to the groove on the front side of the C-shaped purlin a is provided inside the rotating frame 61 on the other side. Through the extension and retraction of the telescopic cylinders 6 and the cooperation of the two telescopic cylinders 6, the bending wheel 7 is moved to a suitable position to bend the C-shaped purlin a. The inner support wheel 71 provides support, ensuring the integrity of the arc shape and preventing deformation of the front side of the C-shaped purlin a when bending with a large arc, thus ensuring the stability of the C-shaped purlin a's shape and improving the bending quality.

[0036] Positioning sleeves 81 are rotatably mounted on the two rotating shafts of the support wheel 71, and the positioning sleeves 81 are mounted on the rotating frame 61. An inner support wheel 8 corresponding to the inner side of the rolled edge of the C-shaped purlin a is rotatably mounted on the positioning sleeve 81. The inner support wheel 8 supports the C-shaped purlin a on the inner side of the rolled edge of the C-shaped purlin a, so as to avoid large deformation of the rolled edge of the C-shaped purlin a when bending, and ensure the bending quality of the C-shaped purlin a.

[0037] When using this bending machine, place the C-shaped purlin a sideways on the support plate 2 and extend it between the pressing wheel 5 and the feeding wheel 3. Start the feeding motor 31 to drive the C-shaped purlin a into the space between the inner limit wheel 4 and the pressing wheel 5. After feeding, start one of the telescopic cylinders 6 to move the bending wheel 7 to a suitable position. The other telescopic cylinder 6 retracts to move the support wheel 71 to avoid the bending wheel. The feeding wheel 3 drives the C-shaped purlin a forward. The bending wheel 7 bends the end of the C-shaped purlin a. After the end is bent, the feeding motor 31 reverses and drives the C-shaped purlin a to move back slightly. Start the telescopic cylinder 6 to extend the support wheel 71 to a suitable position and then drive the C-shaped purlin a forward. At this time, the support wheel 71 and the inner support wheel 8 roll to the inside of the C-shaped purlin a and provide internal support until the bending of the C-shaped purlin a is completed.

[0038] When partial bending is required, adjust the extension positions of the two telescopic cylinders 6 to allow the bending wheel 7 to pass, so that the C-shaped purlin a can be sent out in a straight line. Alternatively, the inner support wheel 8 can be removed to bend the C-shaped purlin a in the middle, thus adapting to the bending requirements of different C-shaped purlins a. This effectively facilitates the use of the bending machine, improves the bending capacity for different C-shaped purlins a, and ensures the bending quality of the C-shaped purlins a.

[0039] Example 2

[0040] Reference Figure 1-5 In this embodiment, it is basically the same as in embodiment one, but with an optimization: multiple limiting bolts 21 are slidably provided inside the support plate 2. The limiting bolts 21 are all vertically fixed on the frame 1. The limiting bolts 21 are threaded with locking nuts 22 on the upper and lower sides of the support plate 2. By rotating the locking nuts 22, the height of the support plate 2 is adjusted to adapt to the curvature of C-shaped purlins a of different sizes, ensuring that the front groove of the C-shaped purlin a matches the position of the feeding wheel 3.

[0041] Example 3

[0042] Reference Figure 1-5 In this embodiment, it is basically the same as in Embodiment 1, but with an optimization: the inner limiting wheel 4 is located between the feeding wheel 3 and the support wheel 71, and the width of the inner limiting wheel 4 matches the inner side dimension of the rolled edge of the C-shaped purlin a. The inner limiting wheel 4 supports the inner side of the C-shaped purlin a, ensuring the bending effect of the bending wheel 7.

[0043] In this embodiment, as Figure 1-5 As shown, both of the two clamping rollers 5 are provided with rotating seats 51 on their downward sides. A mounting plate 52 is vertically provided on the rear side of the frame 1. Adjusting bolts 511 are horizontally threaded through the rotating seats 51. The adjusting bolts 511 pass through the mounting plate 52 and are provided with locking nuts 512. The position of the rotating seats 51 is adjusted by adjusting the adjusting bolts 511, thereby adjusting the clamping rollers 5 to ensure the clamping effect of the clamping rollers 5 on the C-shaped purlin a. The locking nuts 512 are used to lock the clamping effect of the clamping rollers 5.

[0044] In this embodiment, as Figure 1-5 As shown, multiple limiting rods 513 are also slidably provided through the two rotating seats 51, and the limiting rods 513 are all horizontally fixed on the mounting plate 52, which improves the sliding stability of the rotating seats 51 and also ensures the stability of the pressure wheel 5.

[0045] Example 4

[0046] Reference Figure 1-6In this embodiment, it is basically the same as in Embodiment 1, but the more optimized aspect is that the width of the bending wheel 7 is greater than 300 mm, so as to ensure the bending effect of C-shaped purlins a of different specifications, ensure that it can fully contact the back of the C-shaped purlin a, and ensure the bending quality.

[0047] In this embodiment, as Figure 6 As shown, adjusting plates 82 are also fixedly provided on the two positioning sleeves 81. Each adjusting plate 82 has a stud 83 and a limiting slide rod 84 vertically arranged on opposite sides. The limiting slide rod 84 and the stud 83 ensure the stable installation of the adjusting plate 82. The stud 83 and the limiting slide rod 84 pass through both sides of the rotating frame 61. Each stud 83 is threaded with two adjusting nuts 831. The position of the adjusting plate 82 is adjusted by adjusting the nuts 831 in conjunction with the stud 83, thereby adjusting the position of the inner support wheel 8 to adapt to the rolled edge position of different specifications of C-shaped purlins a, ensuring that the position of the inner support wheel 8 matches the rolled edge position of the C-shaped purlin a, and ensuring the bending effect of the C-shaped purlin a.

[0048] In this embodiment, as Figure 6 As shown, both positioning sleeves 81 are rotatably provided with pressure bushings 85 on their outer sides. The gap between the pressure bushings 85 and the inner support wheel 8 matches the thickness of the C-shaped purlin a. The pressure bushings 85 support the rolled edge on the outside of the rolled edge of the C-shaped purlin a, ensuring the stable bending arc at the rolled edge when the C-shaped purlin a is bent, and ensuring the bending quality of the C-shaped purlin a.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
