Description

Technical Field

[0002] Corrugated steel sheets, as a new type of building material, possess excellent mechanical properties, ease of construction, and economy. In applications such as building exterior walls, prefabricated houses, and bridge expansion joints, corrugated steel sheets often require bending to adapt to complex structures. For example, at building corners, the corrugated sheets need to be bent to specific angles. Traditional cutting and splicing methods easily damage the integrity of the sheets, increasing material waste and construction costs. Traditional manual or semi-automatic bending methods suffer from poor precision and low efficiency, making them unsuitable for industrialized production needs. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0029] The following will refer to the appendix. Figures 1 to 6 The present invention will be described in detail with reference to the embodiments.

[0030] Overall, this utility model proposes a bending device for producing corrugated steel sheets, including a top plate 2, a vertical rod 1 fixedly disposed at the bottom of the top plate 2, baffles 201 symmetrically fixedly disposed on the top surface of the top plate 2, a first clamping assembly fixedly disposed on the opposite sides of the two baffles 201, a slot 202 opened at the end of the top plate 2, a movable plate 3 hinged in the slot 202 by a rotating shaft 6, vertical plates 302 fixedly disposed on both sides of the movable plate 3, a second clamping assembly spaced apart on the opposite sides of the two vertical plates 302, and a pressing assembly disposed on the top surface of the top plate 2 and located at the connection between the top plate 2 and the movable plate 3.

[0031] In this embodiment, by setting the first clamping component and the second clamping component, the two ends of the corrugated steel sheet can be clamped and fixed respectively. During the bending process, the displacement or shaking of the corrugated steel sheet can be effectively prevented, ensuring the accuracy and stability of the bending operation and improving the bending quality of the corrugated steel sheet. The movable plate 3 is hinged to the slot 202 of the top plate 2 via the rotating shaft 6. This design allows the bending angle to be flexibly adjusted according to actual production needs. The operator can easily change the included angle between the movable plate 3 and the top plate 2, thereby realizing the processing of corrugated steel sheets at different bending angles and improving production efficiency.

[0032] In addition, the pressing component is set at the connection between the top plate 2 and the movable plate 3, that is, at the bending point of the corrugated steel plate. It can press and fix the bending point of the corrugated steel plate to prevent the corrugated steel plate on the top plate 2 from lifting up during bending, which would affect the bending accuracy and quality.

[0033] Among them, such as Figure 3 and Figure 6 As shown, the second clamping assembly includes a telescopic column 701 slidably connected to the vertical plate 302, a mounting frame 703 fixedly mounted on the inner ends of the telescopic column 701 on both sides of the vertical plate 302, a rotating wheel 7 rotatably mounted on the mounting frame 703, and a spring 702 fitted on the telescopic column 701. One end of the spring 702 is fixedly connected to the mounting frame 703, and the other end is fixedly connected to the vertical plate 302.

[0034] In the second clamping assembly, the telescopic column 701 is slidably connected to the vertical plate 302, and works in conjunction with the spring 702 fitted on the telescopic column 701 to provide a certain degree of elastic buffering capacity. When corrugated steel sheets of different widths are placed in, the spring 702 will automatically extend and retract according to the thickness of the sheet, driving the telescopic column 701 and the mounting frame 703 to move, thereby adjusting the distance between the rotating wheel 7 and the corrugated steel sheet, achieving adaptive clamping for corrugated steel sheets of different thicknesses, improving the versatility of the device, and reducing the trouble of frequently replacing clamping components due to differences in sheet width.

[0035] During bending, the corrugated steel plate on the movable plate 3 bends downwards, causing a change in its length to compensate for the angle during bending. Therefore, the rotating wheel 7 on the mounting frame 703 makes rolling contact with the surface of the corrugated steel plate when clamping it, which can accommodate the change in the length of the corrugated steel plate during bending without affecting the clamping.

[0036] It should be noted that the outer circumference of the rotating wheel 7 is rough. This design increases the friction between it and the corrugated steel plate, preventing it from detaching from the movable plate 3 during bending.

[0037] like Figure 1 As shown, the pressing assembly includes a fixed frame 9 fixedly disposed on the top surface of the top plate 2 and located above the slot 202, an extension post 901 slidably disposed on the top of the fixed frame 9, an abutment part 903 fixedly disposed at the bottom end of the extension post 901, and a tension spring 902 fitted on the part of the extension post 901 located above the fixed frame 9. One end of the tension spring 902 is fixedly connected to the top end of the extension post 901, and the other end is fixedly connected to the fixed frame 9.

[0038] In this embodiment, the tension spring 902, by virtue of its elastic properties, can actively drive the extension column 901 to drive the abutment part 903 to apply a continuous and stable clamping force to the corrugated steel plate on the top plate 2. This effectively prevents the corrugated steel plate from warping due to bending stress.

[0039] In addition, the bending process generates a certain amount of impact and vibration. The elasticity of the tension spring 902 can buffer and dampen the shock. While the contact part 903 presses against the corrugated steel plate, it absorbs and disperses part of the impact force, reducing damage to the corrugated steel plate.

[0040] Among them, such as Figure 3 As shown, the first clamping assembly includes a rubber block 5, a mounting plate 501, and a protrusion 502. The rubber block 5 is fixedly disposed on the opposite side of the two side baffles 201, the mounting plate 501 is fixedly disposed on the side wall of the rubber block 5, and the protrusion 502 is arc-shaped and fixedly disposed on the opposite side of the two side mounting plates 501 at intervals.

[0041] When clamping the corrugated steel sheet, the rubber block 5 can undergo a certain degree of elastic deformation, closely adhering to the surface of the corrugated steel sheet, thus avoiding scratches, indentations, and other damage to the sheet surface that may be caused by rigid clamping. The arc-shaped protrusions 502 spaced apart on opposite sides of the mounting plate 501 can accurately position the corrugated steel sheet during the clamping process and increase the friction between the plate and the steel sheet.

[0042] Based on the above setup, in practice, the operator places the corrugated steel sheet to be bent on the top plate 2, gradually bringing one end of the corrugated steel sheet closer to the first clamping assembly. When the corrugated steel sheet comes into contact with the rubber block 5, the rubber block 5 begins to elastically deform, gradually wrapping around the edge of the corrugated steel sheet, thus clamping the corrugated steel sheet.

[0043] When the other end of the corrugated steel sheet is placed between the rotating wheels 7 of the second clamping assembly on both sides of the movable plate 3, the rotating wheels 7 are compressed, the telescopic column 701 slides within the vertical plate 302, and the spring 702 is compressed. The elastic force of the spring 702 causes the rotating wheels 7 to fit tightly against the corrugated steel sheet, achieving secondary clamping of the corrugated steel sheet and further ensuring the stability of the sheet during bending.

[0044] Subsequently, the operator releases the extension column 901. Under the action of the tension spring 902, the extension column 901 drives the abutment part 903 to gradually approach and eventually make tight contact with the corrugated steel plate, applying a clamping force to the corrugated steel plate to prevent it from warping during bending. Then, according to the bending angle required by production, the operator adjusts the included angle between the movable plate 3 and the top plate 2. The movable plate 3 rotates around the rotating shaft 6, causing the second clamping assembly and one end of the clamped corrugated steel plate to bend downwards. Throughout the bending process, the first clamping assembly maintains a clamping state on the corrugated steel plate.

[0045] Finally, when the corrugated steel sheet is bent to the predetermined angle, the operator stops the operation and releases the first clamping assembly and the second clamping assembly in sequence, so that the corrugated steel sheet can be smoothly removed from the top plate 2.

[0046] As a preferred option, such as Figure 4 As shown, a bending block 301 is fixedly installed on the side of the movable plate 3 near the top plate 2, and the outer side of the bending block 301 is arc-shaped. This configuration ensures that during the bending process of the corrugated steel sheet, the contact surface between the sheet and the bending block 301 is an arc-shaped curved surface. Compared to sharp bending edges, the arc-shaped curved surface allows for a smooth transition during bending of the corrugated steel sheet, reducing the likelihood of cracks, breaks, or other damage at the bending point and improving the yield rate.

[0047] In this embodiment, as Figure 1 and Figure 2 As shown, a support plate 4 is fixedly installed on the upright 1 below the top plate 2, and a power component is provided on the top surface of the support plate 4 to drive the movable plate 3 to rotate downward.

[0048] The power assembly includes a cylinder 401 fixedly mounted on the top surface of the receiving plate 4, a sliding groove 402 fixedly mounted on the end of the cylinder 401, a fixing groove 404 fixedly mounted on the bottom surface of the movable plate 3, and a connecting rod 403 with one end hinged to the sliding groove 402 and the other end hinged to the fixing groove 404. The sliding groove 402 is slidably connected on the top surface of the receiving plate 4.

[0049] In practice, the operator activates cylinder 401, which stretches the piston rod, causing the sliding groove 402 to slide. The connecting rod 403 then drives the movable plate 3 to rotate downwards around the shaft 6. This ensures that the bending angle of the corrugated steel plate strictly adheres to the design requirements, significantly improving bending accuracy.

[0050] It needs to be further explained that, such as Figure 1 and Figure 5 As shown, the bottom surface of the vertical plate 302 is provided with a pressing assembly, which includes a cover plate 8. One side of the cover plate 8 is hinged to one side of the vertical plate 302. Multiple spherical connecting parts 802 are fixedly provided at intervals along the bottom side edge of the cover plate 8. Multiple grooves 803 that cooperate with the connecting parts 802 are spaced apart on the top surface of the other side of the vertical plate 302. A pad block 801 is fixedly provided on the bottom surface of the cover plate 8.

[0051] The pad 801 fixed to the bottom surface of the cover plate 8 further increases the contact area and friction with the corrugated steel plate. When the cover plate 8 presses the corrugated steel plate, the pad 801 can apply pressure evenly, making the plate more stable in the clamped state and reducing the shaking and sliding of the plate during bending. By inserting multiple spherical connecting parts 802 on the side edge of the bottom surface of the cover plate 8 into multiple grooves 803 on the top surface of the vertical plate 302 on the other side, a tight connection between the cover plate 8 and the vertical plate 302 is achieved.

[0052] As a preferred embodiment, such as Figure 4 As shown, an angle plate 601 is fitted onto the rotating shaft 6, and the angle plate 601 is fixedly connected to the top plate 2. Since the angle plate 601 is fixedly connected to the top plate 2 and fitted onto the rotating shaft 6, when the movable plate 3 rotates around the rotating shaft 6 to bend the corrugated steel sheet, a relative angle change will occur between the movable plate 3 and the angle plate 601. Angle scales are engraved on the angle plate 601, allowing the operator to directly observe the corresponding position of the edge of the movable plate 3 and the scale on the angle plate 601 to intuitively understand the current bending angle.

[0053] In addition, such as Figure 1 As shown, in order to facilitate the placement and fixation of this device, a base 101 is fixedly provided at the bottom of the upright 1.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
