[0032] Reference Figure 1The present invention proposes a metal sheet bending mechanism that can be used to bend metal sheets. The metal sheets can be metal sheets made of materials such as iron sheets or aluminum alloy sheets. The metal sheet bending mechanism includes: a first bending assembly 100 and a second bending assembly 200. The first bending assembly 100 includes a first bending member 110 and a first clamping member 120 for clamping the first side of the metal sheet. The first bending member 110 and the first clamping member 120 cooperate with each other to bend the first side of the metal sheet. The second bending assembly 200 includes a second bending member 210 and a second clamping member 220 for clamping the second side of the metal sheet. The second bending member 210 and the second clamping member 220 cooperate with each other to bend the metal sheet. The second side of the sheet is bent, and the first side and the second side of the metal sheet are opposite sides respectively. The first bending component 100 is located on one side of the second bending component 200, and the first clamping member 120 is arranged toward the second clamping member 220, so that the first clamping member 120 and the second clamping member 220 can clamp the first side and the second side at the same time, so that the first bending component 100 and the second bending component 200 can bend the opposite sides of the metal sheet at the same time. The metal sheet bending mechanism simplifies the metal sheet processing process, thereby improving the processing efficiency.

[0033] Reference Figures 1 to 3 The first clamping member 120 is provided with a first inclined surface 1221 inclined upward. The first clamping member 120 clamps the first side of the metal sheet. The first bending member 110 is located on the side of the metal sheet away from the first inclined surface 1221, that is, one end of the first bending member 110 is located on the lower side of the metal sheet. The first bending member 110 can rotate toward the first side of the metal sheet, thereby pushing the first side of the metal sheet to bend upward to perform a first bending on the first side, and then the first bending member 110 can move toward the first side to push the first side to abut against the first inclined surface 1221, thereby performing a first bending on the first side of the metal sheet, so that the first side of the metal sheet has a hook-shaped structure. The second clamping member 220 is provided with a second inclined surface 2211 sloping downward. The second clamping member 220 clamps the second side of the metal sheet. The second bending member 210 is located on the side of the metal sheet facing away from the second inclined surface 2211, that is, one end of the second bending member 210 is located above the metal sheet. The second bending member 210 can rotate toward the second side of the metal sheet, thereby pushing the second side of the metal sheet to bend downward, thereby performing a first bend on the second side. Then, the second bending member 210 can move toward the second side to push the second side to abut against the second inclined surface 2211, thereby performing a second bend on the second side of the metal sheet, so that the second side of the metal sheet has a hook-shaped structure. The metal sheet bending mechanism can simultaneously bend the first and second sides of the metal sheet, that is, the opposite sides, into opposite hook-shaped structures, thereby simplifying the processing process and improving processing efficiency.

[0034] Reference Figures 1 to 3In some embodiments of the present invention, the first clamping member 120 includes a first fixed block 121 and a first movable block 122. The first movable block 122 is rotatably mounted on the first fixed block 121. A first clamping portion 1211 is provided at one end of the first fixed block 121. One end of the first movable block 122 can rotate toward the first clamping portion 1211 and cooperate with the first clamping portion 1211 to clamp the metal sheet. The first movable block 122 can also rotate away from the first clamping portion 1211 to release the metal sheet. It should be noted that the second clamping member 220 includes a second fixed block 221 and a second movable block 222. The second movable block 222 is rotatably mounted on the second fixed block 221. A second clamping portion is provided at one end of the second fixed block 221. One end of the second movable block 222 can rotate toward the second clamping portion and cooperate with the second clamping portion to clamp the metal sheet. The second movable block 222 can also rotate away from the second clamping portion to release the metal sheet.

[0035] It should also be noted that the first bending member 110 is located on one side of the first clamping portion 1211, the first inclined surface 1221 is provided at one end of the first movable block 122, and the first inclined surface 1221 gradually tilts upward in a direction away from the first bending member 110. The first bending member 110 moves toward the first side of the metal sheet and pushes the first side to abut against the first inclined surface 1221, so that the first side has an upward hook-shaped structure; the second bending member 210 is located on one side of the second clamping portion, the second inclined surface 2211 is provided at one end of the second fixed block 221, and the second inclined surface 2211 gradually tilts downward in a direction away from the second bending member 210. The second bending member 210 moves toward the second side of the metal sheet and pushes the second side to abut against the second inclined surface 2211, so that the second side has a downward hook-shaped structure. Therefore, the metal sheet bending mechanism can simultaneously bend the opposite sides of the metal sheet into opposite hooks, and simplifies processing efficiency, thereby improving processing efficiency.

[0036] In some embodiments of the present invention, the first bending member 110 includes a first rotating block 111 and a first movable block 112. The first rotating block 111 is rotatably mounted on the first fixed block 121, and the first movable block 112 is slidably mounted on the first rotating block 111. When the first bending member 110 performs a first bend on the first side of the metal sheet, the first rotating block 111 can drive the first movable block 112 to rotate, so that the end of the first movable block 112 facing the first clamping portion 1211 can rotate toward the first side, thereby pushing the first side to bend. Then, the first movable block 112 can further move toward the first side to push the first side to rotate toward the first inclined surface 1221 and abut against the first inclined surface 1221, thereby performing a second bend on the first side.

[0037] Reference Figure 4 and Figure 5The first rotating block 111 is provided with a slide groove, and the first movable block 112 is slidably installed in the slide groove. The side walls of the slide groove are gradually inclined from the bottom to the middle of the slide groove. The side walls of the first movable block 112 are provided with inclined surfaces corresponding to the slide groove, so that the first movable block 112 can be stably installed in the slide groove. It should be noted that there is a gap between the side walls of the first movable block 112 and the side walls of the slide groove to ensure smooth sliding of the first movable block 112.

[0038] It should also be noted that the second bending member 210 includes a second rotating block and a second movable block 211. The second rotating block can be rotatably mounted on the second fixed block 221, and the second movable block 211 is slidably mounted on the second rotating block. When the second bending member 210 performs the first bending on the second side of the metal sheet, the second rotating block can drive the second movable block 211 to rotate, so that the end of the second movable block 211 toward the second clamping portion can rotate toward the second side, thereby pushing the second side to bend, and then the second movable block 211 can also move toward the second side to push the second side to rotate toward the second inclined surface 2211 and abut against the second inclined surface 2211, thereby performing a second bending on the second side. It should be noted that the installation structure of the second rotating block and the second movable block 211 is the same as the installation structure of the first rotating block 111 and the first movable block 112, and will not be repeated here.

[0039] In some embodiments of the present invention, the first bending assembly 100 further includes a first driving member 130 to drive the reciprocating rotation of the first rotating block 111. The first rotating block 111 is rotatably mounted on the first fixed block 121 via a first rotating shaft. The first driving member 130 includes a first cam 131. The outer periphery of the first cam 131 abuts against an end of the first rotating block 111 away from the first clamping portion 1211. The rotation of the cam drives the first rotating block 111 to reciprocate about the first rotating shaft.

[0040] It should be noted that the first driving member 130 also includes a first driving rod 134 and two first mounting seats 136. The two ends of the first driving rod 134 are respectively rotated and mounted on the first mounting seats 136. For example, bearings can be sleeved on both ends of the first driving rod 134, and the bearings can be installed on the first mounting seats 136. The first cam 131 is fixedly sleeved on the first driving rod 134, and the first driving rod 134 can drive the first cam 131 to rotate.

[0041] A roller is mounted on one end of the first rotating block 111 facing the first cam 131. The outer periphery of the first cam 131 abuts against the roller to improve the rotational stability of the first cam 131, thereby stably and smoothly driving the first rotating block 111 to reciprocate. The first rotating block 111 can be equipped with multiple rollers, such as two or three, depending on actual conditions and not specifically limited here. The first driving rod 134 is equipped with multiple first cams 131, corresponding to the multiple rollers.

[0042] In some embodiments of the present invention, the first driving member 130 further includes a second cam 132. The outer periphery of the second cam 132 abuts against the end of the first movable block 112 away from the first clamping portion 1211. Rotation of the second cam 132 can drive the first movable block 112 to slide along the slide groove. The second cam 132 can be fixedly sleeved on the first driving rod 134, and the first driving rod 134 can drive the second cam 132 to rotate.

[0043] In some embodiments of the present invention, the first driving member 130 further includes a third cam 133. The first movable block 122 is mounted on the first fixed block 121 via a second rotating shaft 1222. The outer periphery of the third cam 133 abuts against the end of the first movable block 122 away from the first clamping portion 1211. Rotation of the third cam 133 can drive reciprocating rotation of the first movable block 122. The third cam 133 can be fixedly sleeved on the first driving rod 134, and the first driving rod 134 can drive the third cam 133 to rotate.

[0044] It should be noted that the first drive rod 134 is also fixedly sleeved with a drive gear 135, which is meshed with the output shaft of the motor, thereby enabling the motor to drive the first drive rod 134 to rotate, and the first drive rod 134 can simultaneously drive the first cam 131, the second cam 132, and the third cam 133 to rotate. It should also be noted that the structures of the protrusions that rotate the first cam 131, the second cam 132, and the third cam 133 are different. The structures of the protrusions of the first drive wheel and the third cam 133 can be adjusted according to the rotation amplitude of the first rotating block 111 and the first movable block 122. The selection of a protrusion with an appropriate structure based on the second cam 132's ability to drive a movable block to slide can be determined based on actual conditions and is not specifically limited here.

[0045] It should also be noted that the second bending assembly 200 includes a second driving member 230, which has the same structure as the first driving member 130. The second driving member 230 drives the second moving block 211 to move, and drives the second rotating block and the second movable block 222 to rotate. The specific structure will not be repeated here.

[0046] In some embodiments of the present invention, the sheet metal bending mechanism further includes a first fixing seat 140 and a first adjusting screw 150. The first adjusting screw 150 is threadedly connected and passed through the first fixing seat 140. The first fixing block 121 is fixedly mounted on the first fixing seat 140. The first bending assembly 100 can be slidably mounted on the frame. The position of the first fixing block 121 can be adjusted by rotating the first adjusting screw 150, thereby adjusting the position of the first bending assembly 100. The sheet metal bending mechanism further includes a second fixing seat 240 and a second adjusting screw 250. The second adjusting screw 250 is threadedly connected and passed through the second fixing seat 240. The second fixing block 221 is fixedly mounted on the second fixing seat 240. The second bending assembly 200 can be slidably mounted on the frame. The position of the second fixing block 221 can be adjusted by rotating the second adjusting screw 250, thereby adjusting the position of the second bending assembly 200. It should be noted that the first adjusting screw 150 and the second adjusting screw 250 are coaxially arranged to adjust the position between the first bending assembly 100 and the second bending assembly 200 according to the distance between the first side and the second side of the metal sheet.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
