[0071] The grooving device 2 is used to form a groove on the plate body, where the groove is one of the first bending portion 15, the second bending portion, and the third bending portion 17.

[0072] The bending device 3 is used to bend the plate body along the groove. Preferably, it is bent by 90°.

[0073] The driving device 4 is used to drive the grooving device 2 and the bending device 3 to move relative to the plate body, and its purpose is to achieve grooving and bending at different positions.

[0074] The welding device is used to weld and fix when the head and tail of the plate body are connected. Among them, the welding device adopts the existing technology, preferably a combination of a manipulator and a welding gun, and will not be elaborated in detail here.

[0075] Among them, at least two grooving devices 2 and bending devices 3 are provided, preferably three grooving devices 2 and two bending devices 3 are provided.

[0076] Specifically, the grooving device 2 includes: a cutting machine 21, a horizontal power member 22, a bracket 23, a moving frame 24, and a lifting power member 25;

[0077] The bracket 23 is used to mount the horizontal power component 22; the moving frame 24 is used to mount the lifting power component 25, and the moving frame 24 is connected to the driving device 4; wherein, the horizontal power component 22 is a linear motor, and both the linear motor and the cutting machine 21 are prior arts and will not be elaborated. The lifting power component 25 includes a rotary motor 251, a trapezoidal lead screw 252, and a trapezoidal nut 253. The trapezoidal nut 253 is fixed to the bracket 23, the rotary motor 251 is mounted on the moving frame 24, the trapezoidal lead screw 252 is rotatably connected to the moving frame 24, and the rotary motor 251 drives the trapezoidal lead screw 252 to rotate, so that the trapezoidal lead screw 252 drives the bracket 23 to rise and fall through the trapezoidal nut 253. A guide block 26 is provided at the top of the moving frame 24, a guide rod 27 is penetrated through the guide block 26, a fixed rod 28 is fixedly provided below the guide rod 27, and a workbench 5 is provided below the fixed rod 28, so that the guide rod 27 is fixed relative to the workbench 5, and the guide rod 27 is used to guide the moving frame 24.

[0078] The horizontal power component 22 is used to drive the cutting machine 21 to move along the length direction of the groove body to the first horizontal position at one end of the plate body and the second horizontal position at the other end of the plate body; and after the cutting machine 21 moves from the first horizontal position to the second horizontal position, the cutting machine 21 completes grooving the plate body.

[0079] The lifting driving component is used to drive the cutting machine 21 to move upward to a trimming position away from the plate body and move downward to a grooving position close to the plate body.

[0080] The lifting power component 25 is used to drive the cutting machine 21 to move from the grooving position to the trimming position when the cutting machine 21 moves from the first horizontal position to the second horizontal position. The purpose is that after grooving is completed, the bracket 23 moves upward, and then the plate body is bent by the bending device 3, while the cutting machine 21 moves to the trimming position, and the cutting machine 21 and some surrounding parts will not interfere with the plate body, and normal bending and normal welding of the plate body can be realized.

[0081] Specifically, the driving device 4 includes a rotary power member 41, a driving lead screw 42, and a driving nut 43. Among them, the rotary power member 41 is a motor. The rotary power member 41 is used to drive the driving lead screw 42 to rotate. The driving nut 43 is threadedly connected to the driving lead screw 42, and the driving nut 43 is connected to the moving frame 24. A support plate 6 is provided on the workbench 5. The support plate 6 is used to mount the rotary power member 41 and the driving lead screw 42. The support plate 6 is also used to mount the fixing rod 28, so that the fixing rod 28 is fixedly connected to the workbench 5 through the support plate 6. Or the fixing rod 28 penetrates through the support plate 6 and is directly fixedly connected to the workbench 5. A guide rail 45 and a slider 44 are also provided on the workbench 5. The guide rail 45 is fixed to the workbench 5, the slider 44 is slidably connected to the guide rail 45, and the slider 44 is fixed to the bottom of the moving frame 24. Thereby, the bottom of the moving frame 24 is guided, and thus guides are provided at both the top and the bottom of the moving frame 24, making the movement of the moving frame 24 smoother and enabling the moving frame 24 to be set to a higher height.

[0082] Three grooving devices 2 are provided so that three grooves are formed on the plate body, which are the first groove, the second groove, and the third groove along the length direction of the plate body respectively. Two driving devices 4 are provided.

[0083] One of the driving devices 4 is used to drive one of the three grooving devices 2 located in the middle along the length direction of the plate body. The driving lead screw 42 of this driving device 4 is a four-cylinder with a single-handed thread, and only one driving nut 43 is provided. The driving nut 43 is fixed to the middle moving frame 24. Among them, two sets of driving lead screws 42 and driving nuts 43 are provided, which can make the moving frame 24 more stable under the driving force.

[0084] The other driving device 4 is used to drive the remaining two grooving devices 2 to approach and move away from each other along the length direction of the plate body. The driving lead screw 42 of this driving device 4 is a lead screw with double-ended double-handed threads, and two driving nuts 43 are provided for this driving device 4. Each driving nut 43 is connected to a thread with a different hand, so as to realize that when the driving lead screw 42 rotates, the two driving nuts 43 approach and move away from each other. One of the driving nuts 43 is fixed to the left moving frame 24, and the other driving nut 43 is fixed to the right moving frame 24. Thus, when the driving lead screw 42 rotates, the two moving frames 24 approach and move away from each other. Thereby, when it is necessary to produce the square three-dimensional road sign 1, different sizes of square three-dimensional road signs 1 can be better specified according to the length of the plate body.

[0085] In this embodiment, the bending device 3 includes a first rotating assembly and a second rotating assembly.

[0086] The first rotating assembly is used to bend one end of the plate body upward along the first groove.

[0087] The second rotating assembly is used to bend the other end of the plate body upward along the second groove, and after the plate body is bent upward along the second groove, the plate body is bent along the third groove.

[0088] The bending direction of the third groove is along the length direction of the plate body and towards the first groove, so as to form a three-dimensional road sign 1 in the shape of a square.

[0089] Specifically, the first rotating assembly includes: a first indexing drive 31 and a first rotating arm 32; wherein, the first indexing drive 31 is a rotary cylinder. The first indexing drive 31 is used to drive the first rotating arm 32 to rotate 90°, so as to realize the upward bending of one end of the plate body along the first groove.

[0090] Specifically, the second rotating assembly includes: a second indexing drive 33, a second rotating arm 34, a third rotating arm 35 and a control component 36. The second indexing drive 33 is a rotary cylinder.

[0091] The control component 36 is used to make the second rotating arm 34 and the third rotating arm 35 have a first control state in which they can rotate relative to each other and a second control state in which they can be limited in parallel to each other; the second rotating assembly is used to rotate the second rotating arm 34 to a first rotating position parallel to the plate body and a second rotating position rotated 90° relative to the first rotating position;

[0092] When the second rotating arm 34 is in the first rotating position, the control component 36 makes the second rotating arm 34 and the third rotating arm 35 in the second control state; when the second rotating arm 34 is in the second rotating position, the control component 36 makes the second rotating arm 34 and the third rotating arm 35 in the first control state.

[0093] Specifically, the control component 36 includes: a rotating body 361, a first stopper 362, a second stopper 363 and an elastic member 364; both the first stopper 362 and the second stopper 363 are plate bodies. The elastic member 364 is a spring.

[0094] The rotating body 361 is fixed to the second rotating arm 34; the third rotating arm 35 is rotatably connected to the rotating body 361; the first stopper 362 is fixed to the rotating body 361, and the second stopper 363 is fixed to the third rotating arm 35; the elastic member 364 is located between the first stopper 362 and the second stopper 363, and the elastic member 364 is fixed to the second stopper 363.

[0095] More specifically, a limiting portion 365 is formed on the third rotating arm 35, and a limiting rod 366 is formed on the second rotating arm 34. The limiting rod 366 is used to abut against the limiting portion 365. When the second rotating arm 34 is parallel to the plate body, the third rotating arm 35 will rotate downward under the action of gravity. Since the limiting portion 365 abuts against the limiting rod 366, the third rotating arm 35 cannot rotate, and the third rotating arm 35 can only be parallel to the second rotating arm 34.

[0096] More specifically, a retaining plate 7 is provided on the support plate 6, and the retaining plate 7 is used to place the plate body to be processed.

[0097] In some embodiments, three sets of grooving devices 2 and three sets of bending devices 3 are provided, so that a rectangular three-dimensional road sign 1 can be prepared.

[0098] In some embodiments, a limiting portion 365 is formed on the third rotating arm 35, and a limiting rod 366 is formed on the second rotating arm 34. The limiting rod 366 is used to abut against the limiting portion 365. When the second rotating arm 34 is parallel to the plate body, the third rotating arm 35 will rotate downward under the action of gravity. Since the limiting portion 365 abuts against the limiting rod 366, the third rotating arm 35 cannot rotate, and the third rotating arm 35 forms an angle less than 180° with the second rotating arm 34, preferably an angle of 175°. Thus, when the second rotating arm 34 is vertical, the third rotating arm 35 will rotate under the action of gravity. Then in some cases, without the first stopper 362, the second stopper 363 and the elastic member 364, it is also possible to achieve that when the second rotating arm 34 is in the first rotating position, the second rotating arm 34 and the third rotating arm 35 are in the second control state; when the second rotating arm 34 is in the second rotating position, the second rotating arm 34 and the third rotating arm 35 are in the first control state.

[0099] Workflow:

[0100] First, place the plate body on the retaining plate 7, and then the driving device 4 drives the grooving device 2 to move along the length direction of the plate body, so that the grooving device 2 moves to the position where grooving is required.

[0101] The lifting power member 25 moves the cutting machine 21 to the grooving position, and then the horizontal power member 22 moves the cutting machine 21 from the first horizontal position to the second horizontal position to achieve grooving of the plate body. Finally, the lifting power member 25 moves the cutting machine 21 to the trimming position through the bracket 23.

[0102] The first rotation driving member 31 drives the first rotating arm 32 to rotate 90°, so that the first planar portion 11 rotates 90° relative to the second planar portion 12 along the first bending portion 15, and the second rotation driving member 33 drives the second rotating arm 34 to rotate 90°, so that the third planar portion 13 rotates 90° relative to the second planar portion 12 along the second bending portion 16.

[0103] Then the second swing arm 34 and the third swing arm 35 are vertical, so that the elastic member 364 will push the first stopper 362 and the second stopper 363. Since the first stopper 362 is fixed relative to the rotating body 361, the first stopper 362 is fixed and cannot move. Furthermore, it will push the second stopper 363. The second stopper 363 is pushed and moves away from the first stopper 362. Thus, the third swing arm 35 moves together with the second stopper 363. The third swing arm 35 is inclined relative to the second swing arm 34. Thus, the third swing arm 35 rotates under the action of gravity, so that the fourth flat portion 14 rotates relative to the third flat portion 13 along the third bending portion 17, thereby driving the fourth flat portion 14 to rotate until the fourth flat portion 14 contacts the first flat portion 11.

[0104] When the second swing arm 34 is parallel to the plate body, the third swing arm 35 will rotate downward under the action of gravity. Since the limiting portion 365 abuts against the limiting rod 366, the third swing arm 35 cannot rotate and can only be parallel to the second swing arm 34.

[0105] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features having similar functions disclosed in the embodiments of the present disclosure.
