Specific embodiments

[0017] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor all belong to the protection scope of the present utility model.

[0018] Please refer to Figures 1-4 , a sheet metal bending device, including a workbench 1 with a top plate 2 fixedly arranged above, and a bending mechanism arranged on the workbench 1 for bending sheet metal. The bending mechanism includes a pressing block 3 arranged between the workbench 1 and the top plate 2, a rotating rod 10 fixedly arranged on the bottom wall of the bending groove 4 and parallel to the pressing block 3, two supporting blocks 5 that are symmetric about the rotating rod 10 left and right and whose bottom sides are rotationally connected to the rod body of the rotating rod 10, and a control component arranged in the workbench 1. The control component controls the sides of the two supporting blocks 5 away from the rotating rod 10 to move away from or close to each other, and fixes the position between the two supporting blocks 5; a bending groove 4 is opened at the position of the top end face of the workbench 1 below the pressing block 3.

[0019] As Figures 1-2 shown, place a flat sheet metal part on the top end face of the workbench 1, and drive the pressing block 3 to move downward through the pressing component, press the sheet metal part placed on the top end face of the workbench 1 into the bending groove 4 for bending, and cooperate with the two supporting blocks 5 arranged in the bending groove 4, then the bending operation of the sheet metal part can be realized. When it is necessary to bend the sheet metal part at multiple angles, control the sides of the two supporting blocks 5 away from the rotating rod 10 to move away from or close to each other through the control component, adjust the angle between the two supporting blocks 5, so that when the pressing block 3 moves downward to press the sheet metal part, the sheet metal part can be resisted on the two supporting blocks 5, facilitating the bending operation of the sheet metal part at different angles, and can conveniently bend the flat sheet metal part at different angles, improving the bending efficiency of the sheet metal part.

[0020] A control groove 7 is formed on the top end face of the workbench 1, and the length direction of the opening of the control groove 7 is perpendicular to the length direction of the rotating rod 10; the control assembly includes a driven rod 6 fixedly arranged on the side faces of the two support blocks 5 away from the rotating rod 10, two cross bars 8 respectively arranged in the control groove 7 on the mutually away sides of the two driven rods 6 and the adjacent ends of which are respectively rotatably connected to the rod bodies of the driven rods 6, two vertical rods 11 arranged vertically and fixedly connected to the bottom sides of the mutually away ends of the two cross bars 8 respectively, a slider 12 fixedly arranged at the bottom end of the vertical rod 11, a sliding rod 13 arranged horizontally and movably penetrating through the two sliders 12, and a control member arranged in the control groove 7 and controlling the vertical lifting movement of the sliding rod 13.

[0021] As Figures 1-3 shown, when the sheet metal part needs to be bent at different angles, the control member drives the sliding rod 13 to move up and down in the control groove 7. When the sliding rod 13 moves upward, the two sliders 12 are connected to the driven rod 6 on the support block 5 through the vertical rod 11 and the cross bar 8. At this time, the two sliders 12 approach each other on the sliding rod 13, driving the mutually away sides of the two support blocks 5 to approach each other, reducing the angle between the two support blocks 5. When the sliding rod 13 moves downward, the two sliders 12 move away from each other on the rod body of the sliding rod 13. At this time, the mutually away sides of the two support blocks 5 move away from each other, increasing the angle between the two support blocks 5, realizing the free adjustment of the angle between the two support blocks 5, and facilitating the subsequent bending operation of the sheet metal part at different angles.

[0022] Limit grooves 14 are formed in the groove walls of the control groove 7 at positions adjacent to both ends of the sliding rod 13 in the vertical direction, and limit blocks 15 slidably arranged in the limit grooves 14 and fixedly connected to the end portions of the sliding rod 13 are provided.

[0023] As Figure 3 shown, both ends of the sliding rod 13 pass through the limit grooves 14 through the limit blocks 15. When the control member drives the sliding rod 13 to move up and down in the control groove 7, the limit blocks 15 slide in the limit grooves 14, facilitating the stable lifting of the sliding rod 13 in the control groove 7.

[0024] The control member includes a lifting block 19 arranged between the two sliders 12 and fixedly connected to the sliding rod 13, a lifting screw rod 16 arranged vertically in the control groove 7 and penetrating through the lifting block 19, and a threaded block 24 arranged in the control cavity 22 and threadedly connected to the lifting screw rod 16 through a control structure. A control cavity 22 is formed inside the lifting block 19.

[0025] Two threaded blocks 24 are symmetrically arranged on the left and right about the lifting lead screw 16 in the control cavity 22. The control structure includes two clamping rods 21, one ends of which are respectively vertically and fixedly arranged on the end faces of the two threaded blocks 24 away from each other and movably penetrate through the moving slots 20 formed in the lifting block 19, a limiting spring 23 movably sleeved on the rod bodies of the clamping rods 21 and fixedly connected to the side faces of the threaded blocks 24 and the inner wall of the control cavity 22 at both ends, and two electromagnets movably sleeved on the rod bodies of the clamping rods 21 and respectively fixedly arranged on the side faces of the threaded blocks 24 and the inner wall of the control cavity 22. When the limiting spring 23 is in a normal extended state, the two threaded blocks 24 move away from each other; a positioning slot 17 is vertically formed in the control slot 7 near the opening position of the moving slot 20, and a plurality of card slots 18 matching the ends of the clamping rods 21 are equidistantly arranged in the vertical direction on the bottom wall of the positioning slot 17.

[0026] When the limiting spring 23 is in a normal extended state, the end of the clamping rod 21 penetrates through the card slot 18.

[0027] As Figures 1-4 shown, when it is necessary to change the included angle between the two support blocks 5, the adjacent ends of the two electromagnets sleeved on the same clamping rod 21 are controlled to have the same magnetic poles, and the two threaded blocks 24 are controlled to approach each other to stretch the limiting spring 23, so as to facilitate the threaded connection between the two threaded blocks 24 and the lifting lead screw 16. At the same time, during the movement of the threaded block 24, the end of the clamping rod 21 is driven to move away from the card slot 18, so that the lifting block 19 can move up and down in the control slot 7. When the lifting block 19 moves to a suitable position, the power supply to the two electromagnets is disconnected. During the process of the set limiting spring 23 restoring to the normal extended state, the two threaded blocks 24 move away from each other, and the ends of the clamping rods 21 synchronously arranged on the threaded blocks 24 penetrate through the card slots 18 to fix the position of the lifting block 19, that is, to fix the positions of the two support blocks 5, which is convenient for subsequent bending operations on the sheet metal parts, and can conveniently bend the flat sheet metal parts at different angles, improving the bending efficiency of the sheet metal parts.
