[0003] In order to overcome the above-mentioned defects in the existing technology, this utility model provides an automatic U-folding device for household appliance boxes.

[0004] An automatic U-folding device for household appliance casings includes a worktable for placing bent workpieces. The workpieces have centering positioning components on both sides, each including a horizontally movable limiting block. A limiting block is located on the side of the worktable away from the loading end. The workpieces have stamping rollers on both sides, mounted on a lifting mechanism. A feeding conveyor belt is located at the front of the worktable, and a material ejection mechanism is located at the rear. The material ejection mechanism includes a movable frame slidably connected to the machine frame.

[0005] Furthermore, the positioning block is mounted on the support frame, the bottom of the support frames on both sides of the worktable is slidably connected to the slide rail, the slide rail is mounted on the base plate, and the bottom of the two support frames is connected to both ends of the bidirectional lead screw mounted on the base plate. The bidirectional lead screw is driven to rotate by a power source.

[0006] Furthermore, the lifting mechanism includes a lifting plate connected to the stamping roller frame, the lifting plate being connected to the output end of the stamping cylinder, the stamping cylinder being fixedly mounted on the frame, the lifting plate being connected to a guide rod, and the guide rod being slidably connected to the frame.

[0007] Furthermore, the height of the feeding conveyor belt is slightly lower than the height of the workbench.

[0008] Furthermore, the movable frame is connected to the unloading cylinder installed on the frame, and the unloading cylinder drives the movable frame to push the workpiece on the worktable onto the unloading conveyor belt.

[0009] Furthermore, the top of the workbench is provided with an upper pressure plate, the top of which is connected to the output end of the lifting hydraulic cylinder, which is mounted on the frame.

[0010] Due to the adoption of the above technical solutions, the beneficial technical effects of this utility model are as follows: In this utility model, a limiting block is set, and the edge of the workpiece abuts against the limiting block. By moving the positioning blocks on the two sets of positioning components to the center at the same time, the workpiece is centered. The stamping roller moves upward to push the bending part of the workpiece to bend. After bending, the workpiece moves from the worktable to the unloading conveyor belt under the action of the unloading mechanism, realizing automatic unloading. This utility model realizes the centering positioning and automatic unloading of the workpiece, and has high bending accuracy and efficiency. Attached Figure Description

[0019] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0020] according to Figure 1-7 As shown, an automatic U-shaped folding device for household appliance boxes includes a worktable 1 for placing a bending workpiece 17. The workpiece 17 has a centering positioning component on both sides, and the positioning component includes a positioning block 6 that moves in the horizontal direction. A limiting block 2 is provided on the side of the worktable 1 away from the loading end. The workpiece 17 has a stamping roller 3 on both sides, and the stamping roller 3 is mounted on a lifting mechanism. The front side of the worktable 1 has a feeding conveyor belt 4, and the rear side has a material unloading mechanism. The material unloading mechanism includes a movable frame 5 that is slidably connected to a frame 18.

[0021] In the above specific technical solution, a limiting block 2 is set, and the edge of the workpiece 17 abuts against the limiting block 2. The positioning blocks 6 on the two sets of positioning components move towards the middle at the same time, so that the workpiece 17 is centered. The stamping roller 3 moves upward to push the bending part of the workpiece 17 to bend. After bending, the workpiece 17 moves from the worktable 1 to the unloading conveyor belt under the action of the unloading mechanism, realizing automatic unloading. This utility model realizes the centering positioning and automatic unloading of the workpiece 17, and has high bending accuracy and efficiency.

[0022] The positioning block 6 is mounted on the support frame 7. The bottom of the support frames 7 on both sides of the worktable 1 is slidably connected to the slide rail 8. The slide rail 8 is mounted on the base plate 9. The bottom of the two support frames 7 is connected to both ends of the bidirectional lead screw 10 mounted on the base plate 9. The bidirectional lead screw 10 is driven to rotate by a power source. When the power source (not shown in the figure) is started, the power source can be set to a motor connected to a chain and sprocket drive, which drives the bidirectional lead screw 10 to rotate, so that the support frames 7 can move to the center or both sides at the same time. When the support frames 7 move to the center at the same time, the workpiece 17 can be positioned in the center.

[0023] The top of the workbench 1 is provided with an upper pressure plate 15, the top of which is connected to the output end of the lifting cylinder 16, which is mounted on the frame 18.

[0024] The lifting mechanism includes a lifting plate 11 connected to the stamping roller frame 12. The lifting plate 11 is connected to the output end of the stamping cylinder 19. The stamping cylinder 19 is fixedly installed on the frame 18. The lifting plate 11 is connected to the guide rod 13. The guide rod 13 is slidably connected to the frame 18.

[0025] In the above specific technical solution, after the workpiece 17 is positioned by the centering positioning component, the upper pressure plate 15 descends and presses on the unbent part of the workpiece 17. The edge of the upper pressure plate 15 coincides with the bent edge of the workpiece 17. Then, the support frame 7 moves to both sides under the action of the bidirectional lead screw 10, and the stamping roller 3 moves upward under the action of the stamping cylinder 19 to stamp and bend the bent part of the workpiece 17.

[0026] The height of the unloading conveyor belt 4 is slightly lower than the height of the workbench 1, which facilitates the automatic unloading of the workpiece 17.

[0027] The movable frame 5 is connected to the ejector cylinder 14 installed on the frame 18. The ejector cylinder 14 drives the movable frame 5 to push the workpiece 17 on the workbench 1 onto the unloading conveyor belt 4. After the workpiece 17 is stamped, the upper pressure plate 15 rises, the ejector cylinder 14 is activated, and the movable frame 5 moves toward the unloading conveyor belt 4, pushing the workpiece 17 onto the unloading conveyor belt 4 to complete the automatic unloading.

[0028] The above embodiments are merely exemplary embodiments of the present utility model and are not intended to limit the present utility model. The scope of protection of the present utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present utility model.
