[0027] Please refer to Figures 1 to 5The embodiment of the present application provides a galvanized iron sheet bending device, which may include: a bracket 1, a top plate 2, two vertical plates 3, a first plate 4, a second plate 5, a shift rod 6, a connecting plate 7, an angle adjustment plate 8, an angle adjustment bolt 9 and an angle adjustment nut 10, wherein the top plate 2 is fixed to the bracket 1; the two vertical plates 3 are respectively arranged on both sides of the length direction of the top plate 2; the first plate 4 is horizontally arranged between the two vertical plates 3 and is hinged to the two vertical plates 3; the second plate 5 is horizontally fixed between the two vertical plates 3 and is on the same level as the first plate 4. On the horizontal plane; the shift rod 6 is arranged on the first plate 4 and is on the side of the vertical plate 3 away from the other vertical plate 3; the connecting plate 7 is connected to the side of the top plate 2 facing the bracket 1; the angle adjustment disk 8 is fixed on the connecting plate 7, and a circular arc-shaped angle adjustment groove 801 is provided on the angle adjustment disk 8, and a scale line is provided near the angle adjustment groove 801 on the angle adjustment disk 8; the angle adjustment bolt 9 is arranged in the angle adjustment groove 801 and contacts the shift rod 6; the angle adjustment nut 10 is arranged on the side of the angle adjustment disk 8 facing the vertical plate 3 and is threadedly engaged with the angle adjustment bolt 9.
[0028] In this embodiment, when bending the galvanized iron sheet, the galvanized iron sheet to be bent is placed between the first plate 4 and the second plate 5. The angle adjustment bolt 9 is rotated to loosen the fit between the angle adjustment bolt 9 and the angle adjustment nut 10, thereby allowing the angle adjustment bolt 9 to slide within the angle adjustment slot 801. After sliding to the desired angle, the angle adjustment bolt 9 is tightened to change the angle at which the lever 6 contacts the angle adjustment bolt 9, causing the first plate 4 to rotate relative to the vertical plate 3 until the lever 6 is blocked by the angle adjustment bolt 9, completing the bending of the galvanized iron sheet. Since the angle adjustment disk 8 is provided with scale lines, the angle between the first plate 4 and the second plate 5 can be visually observed, thereby accurately controlling the bending angle of the galvanized iron sheet.
[0029] See also Figure 4 The first plate 4 may include: a plate body 401, a first shaft sleeve 402, a first shaft 403, a second shaft sleeve 404 and a second shaft 405, wherein the first shaft sleeve 402 is arranged on the side of the plate body 401 facing the bracket 1; the first shaft 403 is arranged on the side of the first shaft sleeve 402 facing the vertical plate 3, the first shaft 403 is hinged to the vertical plate 3 and extends out of the vertical plate 3, and the gear lever 6 is fixed on the first shaft 403; the second shaft sleeve 404 is arranged on the side of the plate body 401 facing the bracket 1 and is opposite to the first shaft sleeve 402 in the length direction of the plate body 401; the second shaft 405 is arranged on the side of the second shaft sleeve 404 facing the other vertical plate 3, and the second shaft 405 is hinged to the corresponding vertical plate 3.
[0030] In this embodiment, through the settings of the first shaft 403 and the second shaft 405, the first plate 4 can rotate between the two vertical plates 3, so as to realize the adjustment of the included angle with the second plate 5. The first shaft sleeve 402 and the second shaft sleeve 404 not only provide a stable installation position for the first shaft 403 and the second shaft 405, but also provide the necessary support for the rotation of the first plate 4. In addition, the stop rod 6 is fixed on the first shaft 403, so that the angle adjustment bolt 9 can directly act on the stop rod 6, and then push the first plate 4 to rotate, realizing the precise adjustment of the angle.
[0031] Please refer to Figure 1 、 Figure 3 , a first bearing 11 is arranged on the first shaft 403, and the first bearing 11 is fixed in the vertical plate 3; a second bearing 12 is arranged on the second shaft 405, and the second bearing 12 is fixed in the other vertical plate 3.
[0032] Among them, by arranging the first bearing 11 and the second bearing 12, not only the rotation of the first shaft 403 and the second shaft 405 is smoother, reducing friction and wear and extending the service life, but also the stability of the first plate 4 during the rotation process is enhanced. The first bearing 11 and the second bearing 12 are respectively fixed in the two vertical plates 3, providing stable support and guiding functions for the first shaft 403 and the second shaft 405, ensuring the accuracy and reliability of the first plate 4 when adjusting the angle. In addition, the use of bearings can also effectively reduce the noise and heat generated by friction, further improving the overall performance and safety of the device. In short, by adding the settings of the first bearing 11 and the second bearing 12, the galvanized iron sheet bending device of the embodiment of the present utility model ensures the bending accuracy while improving the stability and service life of the device, and further enhancing its practicability and reliability.
[0033] Please refer to Figures 1 to 3 , a moving plate 13 is slidably arranged on the side of the first plate 4 facing the bracket 1, and a handle 14 is arranged on the moving plate 13.
[0034] Specifically, the setting of the moving plate 13 allows the operator to conveniently control the movement of the first plate 4 in the horizontal direction, so as to further adjust the position of the galvanized iron sheet during the bending process. Through the handle 14, the operator can easily push or pull the moving plate 13 to slide along the first plate 4 to meet the requirements of different bending positions of the galvanized iron sheet. This design not only improves the convenience of operation, but also increases the flexibility and adaptability of the device.
[0035] Through the improvements of this embodiment, the galvanized iron sheet bending device not only has the ability to precisely control the bending angle and clamping force, but also has the function of adjusting the bending position of the galvanized iron sheet. This makes the device applicable to a wider variety of galvanized iron sheet bending needs, further improving its practicality and scope of application. Furthermore, the design of the movable plate 13 and handle 14 also makes operation more convenient and efficient, improving work efficiency and safety.
[0036] Furthermore, a slider is provided on the side of the first plate 4 facing the movable plate 13 , and a slide rail is provided on the side of the movable plate 13 facing the first plate 4 , and the slider is fitted on the slide rail.
[0037] In this embodiment, the coordinated use of the slider and rail provides precise guidance and stable support for the sliding movement of the movable plate 13 on the first plate 4. The slider is designed to closely mate with the rail, ensuring smooth and precise sliding of the movable plate 13 and effectively preventing any deviation or shaking during the sliding process. This design not only improves operational stability but also increases the durability and reliability of the device.
[0038] Through the improvements of this embodiment, the galvanized iron sheet bending device further enhances its ability to adjust the bending position of the galvanized iron sheet while maintaining precise control of the bending angle and clamping force. The combined use of the slider and rail provides precise guidance and stable support for the sliding of the movable plate 13, enabling the device to adapt to a wider range of galvanized iron sheet bending needs. This design also makes operation more convenient and efficient, improving work efficiency.
[0039] See also Figures 1 to 3 The galvanized iron sheet bending device may further include: a vertical plate 15 , wherein the vertical plate 15 is arranged between the two vertical plates 3 , and there are gaps between the vertical plate 15 and the first plate 4 and the second plate 5 .
[0040] In this embodiment, the provision of vertical plate 15 not only enhances the structural stability of the galvanized iron sheet bending apparatus but also provides a convenient support point for the operator. During the bending process, the operator can secure one end of the galvanized iron sheet to vertical plate 15 while performing the bending operation on the other end, thereby ensuring accurate and stable bending. The gap between vertical plate 15 and the first and second plates 4, 5 ensures that the galvanized iron sheet can pass smoothly during the bending process, avoiding friction and collision with other parts of the apparatus, further ensuring bending accuracy and efficiency.
[0041] Furthermore, the height of the vertical plate 15 can be adjusted as needed to accommodate the bending requirements of galvanized iron sheets of varying specifications and thicknesses. Adjusting the height of the vertical plate 15 can alter the support point of the galvanized iron sheet during the bending process, thereby achieving different bending effects. Furthermore, the position of the vertical plate 15 can be fine-tuned to ensure an appropriate gap between it and the first and second plates 4, 5. This ensures smooth passage of the galvanized iron sheet while preventing a decrease in bending accuracy due to an excessively large gap.
[0042] See also Figures 1 to 3 , both vertical plates 3 are provided with matching grooves, and the vertical plates 15 are slidably matched in the matching grooves.
[0043] In this embodiment, the design of the matching groove allows the riser 15 to slide and adjust between the two uprights 3, further increasing the flexibility and adaptability of the galvanized iron sheet bending device. The operator can easily adjust the position of the riser 15 to the optimal support point according to the actual bending requirements, thereby ensuring the accuracy and stability of the bending.
[0044] See also Figure 2 The galvanized iron sheet bending device may further include: a transmission mechanism 16, a rocker 17 and a screw 18, wherein the transmission mechanism 16 is arranged on the side of one of the vertical plates 3 away from the first plate 4; the rocker 17 is fixed to the input end of the transmission mechanism 16; the screw 18 is connected to the output end of the transmission mechanism 16, and the screw 18 passes through the vertical plate 15 and is threadedly engaged with the vertical plate 15.
[0045] In this embodiment, the coordinated use of transmission mechanism 16, rocker 17, and screw 18 provides a more precise and convenient method for adjusting the position of riser 15. Transmission mechanism 16, through the coordinated operation of its internal components, converts the rotational motion of rocker 17 into linear motion of screw 18. The threaded engagement of screw 18 with riser 15 ensures stability and precision during adjustment.
[0046] Specifically, to adjust the position of riser 15, the operator simply rotates rocker 17 slightly, causing transmission mechanism 16 to drive screw 18 in linear motion. Because screw 18 engages with riser 15 through a threaded connection, riser 15 moves along the axis of screw 18, thereby changing its position between the two uprights 3. This adjustment method is not only simple to operate but also highly precise, meeting various complex bending requirements.
[0047] See also Figure 2 、 Figure 3, the transmission mechanism 16 may include: a housing 1601, a first bevel gear 1602, and a second bevel gear 1603. Among them, the housing 1601 is fixed to one side of the vertical plate 3 facing away from the first plate 4; the first bevel gear 1602 is connected to the end of the rocker 17; the second bevel gear 1603 is connected to the end of the screw 18, and the second bevel gear 1603 meshes with the first bevel gear 1602.
[0048] In this embodiment, through the meshing transmission of the first bevel gear 1602 and the second bevel gear 1603, the conversion of the rotational motion of the rocker 17 to the linear motion of the screw 18 is achieved. This transmission method has the advantages of compact structure, high transmission efficiency, stable transmission ratio, etc., making the position adjustment of the vertical plate 15 more accurate and reliable.
[0049] In addition, both the first bevel gear 1602 and the second bevel gear 1603 are installed inside the housing 1601, which can effectively protect the gears from the influence of the external environment, and at the same time facilitate the lubrication and maintenance of the gears. The housing 1601 is fixed to the vertical plate 3, ensuring the stability and reliability of the transmission mechanism 16 and further improving the overall performance of the device.
[0050] Please refer to Figure 5 , a chute 19 is provided on one side of the angle adjustment disk 8 facing the first plate 4. The chute 19 is arranged along the angle adjustment groove 801, and the angle adjustment nut 10 is slidably fitted in the chute 19.
[0051] In this embodiment, the setting of the chute 19 facilitates the angle adjustment nut 10 not to rotate when the operator screws the angle adjustment bolt 9. When the operator rotates the angle adjustment bolt 9, since the angle adjustment nut 10 is restricted to slide in the chute 19, it will not rotate with the bolt, which greatly simplifies the operation process and improves the accuracy of angle adjustment.
[0052] The chute 19 is arranged along the angle adjustment groove 801, ensuring that when the angle adjustment nut 10 slides in the chute 19, its position always corresponds to the angle adjustment groove 801, thereby realizing the precise adjustment of the angle adjustment bolt 9. This design enables the operator to easily adjust the bending angle to meet different bending requirements.
[0053] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
