Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.
[0023] Please also refer to Figure 1 Now, the metal plate bending device provided by the utility model is described. The metal plate bending device includes a frame 10, a positioning mechanism 30 and a bending drive member 50; the frame 10 is provided with a bending platform 11 for placing the sheet 60 to be folded, and a bending movable mold 20 is provided at both ends of the bending platform 11; the positioning mechanism 30 is provided on the frame 10, located above the bending platform 11, and the positioning mechanism 30 is symmetrically provided with two mutually hinged swing arms 31, and the swing ends of the two swing arms 31 are provided with a bending fixed mold 40, and the two bending fixed molds 40 are both used to press the sheet 60 to be folded and form an inclined state at both ends of the sheet 60 to be folded; the bending drive member 50 is provided on the frame 10, and the output end is connected to the bending movable mold 20; wherein, the bending movable mold 20 is used to cooperate with the bending fixed mold 40 in the inclined state to bend the sheet 60 to be folded once under the drive of the bending drive member 50, and to bend the sheet 60 to be folded for a second time after the bending fixed mold 40 is separated from the sheet 60 to be folded.
[0024] When the folding plate 60 is detached from the bending fixed die 40, the bending driving member 50 drives the bending movable die 20 to bend, and the bent bending movable die 20 bends the folding plate 60 and makes the folding plate 60 fit the surface of the folding plate 60 and the bending fixed die 40, thereby completing one bending; since the bending fixed die 40 is in an inclined state when pressing the folding plate 60, the bending part of the folding plate 60 after one bending is also in an inclined state, which can provide the demoulding space for the bending fixed die 40 to detach from the folding plate 60, so that the bending fixed die 40 can detach from the folding plate 60 smoothly; when the bending fixed die 40 detaches from the folding plate 60, the bending driving member 50 drives the bending movable die 20 to perform a second bend on the folding plate 60, thereby completing the bending process of the folding plate 60.
[0025] The beneficial effect of the metal plate bending device provided by the present invention is that: compared with the existing technology, the present invention uses two mutually hinged swing arms 31 to make the bending fixed mold 40 press against the sheet material 60 to be folded, and drives the bending movable mold 20 to bend through the bending drive member 50, and cooperates with the bending fixed mold 40 in an inclined state to bend the sheet material 60 to be folded once, so that the sheet material 60 to be folded has the moving space to make the bending fixed mold 40 separate from the sheet material 60 to be folded after completing one bending. After the bending fixed mold 40 separates from the sheet material 60 to be folded, a second bending is performed to complete the bending operation of the sheet material 60 to be folded, which can avoid the side constraints of the sheet material 60 to be folded by multiple bending, so that the sheet material 60 to be folded can be smoothly demolded, thereby improving the bending efficiency of the sheet material 60 to be folded.
[0026] In one possible implementation, see Figure 2 and Figure 3 The positioning mechanism 30 includes a lifting drive member 32, a lifting plate 33 and two swing arms 31; the lifting drive member 32 is arranged on the frame 10; the lifting plate 33 is located below the lifting drive member 32 and is connected to the output end of the lifting drive member 32, and the bottom wall of the lifting plate 33 is provided with a hinge rod 34; the two swing arms 31 are both hinged to the hinge rod 34.
[0027] It should be noted that the lifting drive member 32 can be a cylinder, the output end of which is connected to the lifting plate 33, which can control the displacement of the lifting plate 33 in the vertical direction. A fixed plate can be provided on the frame 10, and the lifting plate 33 is slidably connected to the fixed plate, which can improve the connection strength of the lifting plate 33; the swing arm 31 has two hinged ends, which are respectively hinged to the two ends of the hinge rod 34, which can improve the connection strength between the swing arm 31 and the lifting plate 33.
[0028] In one possible implementation, see Figure 2The bending fixed mold 40 includes a first plate 41, a second plate 42 and a third plate 43. The first plate 41 is used to horizontally press the sheet 60 to be folded. The second plate 42 is inclined and one end is connected to the first plate 41. The third plate 43 is vertically connected to the second plate 42. Among them, the second plate 42 and the third plate 43 are both used to cooperate with the bending movable mold 20 to bend the sheet 60 to be folded once.
[0029] It should be noted that the cross-sectional shape of the bending fixed die 40 can be a right-angled trapezoid, and the first plate body 41 is used to press the sheet 60 to be folded against the bending platform 11 to prevent the sheet 60 to be folded from separating from the bending platform 11 during the bending process. One end of the second plate body 42 is connected to the first plate body 41, and the other end is inclined in the direction away from the bending platform 11. One end of the third plate body 43 is vertically connected to the second plate body 42. The inclined second plate body 42 and the third plate body 43 both cooperate with the bending movable die 20 to bend the sheet 60 to be folded once. After one bending, the sheet 60 to be folded matches the shape of the second plate body 42 and the third plate body 43. After one bending, the sheet 60 to be folded has a trapezoidal moving space for the bending fixed die 40 to separate from the sheet 60 to be folded, so that the bending fixed die 40 can separate from the sheet 60 to be folded, avoiding the side of the sheet 60 to be folded being constrained by multiple bending, thereby affecting the subsequent bending process of the sheet 60 to be folded.
[0030] In one possible implementation, see Figure 2 A connecting rod 421 is provided on the second plate body 42 , and the connecting rod 421 is hinged to the swing end of the swing arm 31 .
[0031] It should be noted that the positioning mechanism 30 controls the swing arm 31 to move downward so that the bending fixed mold 40 contacts the to-be-folded sheet 60, and the two swing arms 31 hinged to each other drive the two bending fixed molds 40 to move in relative directions on the sheet 60 to be folded. When the bending fixed mold 40 reaches the bending position of the sheet 60 to be folded, the bending drive 50 drives the bending movable mold 20 to bend the sheet 60 to be folded once. After the sheet 60 to be folded is bent once, the swing arm 31 drives the bending fixed mold 40 to separate from the sheet 60 to be folded. Since the second plate body 42 is hinged to the swing end of the swing arm 31, the two swing arms 31 will drive the two bending fixed molds 40 to slide on the sheet 60 to be folded and move closer to each other when they swing and move closer to each other, so that the bending fixed mold 40 can separate from the sheet 60 to be folded, avoiding the multiple bending of the sheet 60 to be folded from constraining the bending fixed mold 40 and affecting the subsequent bending processing of the sheet 60 to be folded.
[0032] In one possible implementation, see Figure 3A first limiter 311 is provided at the hinged position between the connecting rod 421 and the swing arm 31. The first limiter 311 is used to limit the rotation angle of the connecting rod 421 relative to the swing arm 31; a second limiter 312 is provided at the position where the two swing arms 31 are hinged to each other. The second limiter 312 is used to limit the relative swing angle of the two swing arms 31.
[0033] It should be noted that the first limit member 311 can limit the rotation angle between the bending fixed mold 40 and the swing arm 31. When the two swing arms 31 drive the bending fixed mold 40 to abut the front folding plate 60, it is ensured that the first plate body 41 abuts the front folding plate 60 when it moves to the upper surface of the plate 60 to be folded, so as to avoid the bending fixed mold 40 being offset due to its own gravity, and the first plate body 41 cannot effectively abut the front folding plate 60. The first limit member 311 can limit the rotation of the bending fixed mold 40, so as to ensure the plate 60 to be folded. Pressing and positioning; when the two swing arms 31 move closer to each other and shrink, the second limit member 312 limits the angle between the two swing arms 31 to avoid the distance between the two swing arms 31 being too close, so that the two swing arms 31 are in an inclined state after shrinking. When the two inclined swing arms 31 drive the bending fixed die 40 to press against the sheet material 60 to be folded, the inclined swing arms 31 can reduce the distance that the bending fixed die 40 slides on the sheet material 60 to be folded, so that the bending fixed die 40 can quickly press against the sheet material 60 to be folded, thereby improving the bending efficiency of the sheet material 60 to be folded.
[0034] In one possible implementation, see Figure 1 The bending movable mold 20 includes a first template 21 and a second template 22. One end of the first template 21 is rotatably connected to the bending platform 11, and the other end is rotatably connected to the second template 22. The first template 21 and the second template 22 are respectively connected to the bending driving member 50.
[0035] It should be noted that the sheet material 60 to be folded needs to be bent multiple times. The first template 21 rotatably connected to the bending platform 11 first bends the sheet material 60 to be folded for one section, and then performs a second bend on the sheet material 60 through the second template 22 rotatably connected to the first template 21, so that the sheet material 60 to be folded completes multiple bending; after one bending, the first template 21 bends the sheet material 60 to be folded for a second time, so that the sheet material 60 to be folded completes the bending process.
[0036] In one possible implementation, see Figure 3 and Figure 4 The bending drive member 50 includes a first rotating drive member 51 and a second rotating drive member 52; the first rotating drive member 51 is arranged on the frame 10, and the output end of the first rotating drive member 51 is connected to the first rolling member 53, and the first rolling member 53 rolls the bottom wall of the first template 21; the second rotating drive member 52 is arranged on the first template 21; the output end of the second rotating drive member 52 is connected to the second rolling member 54, and the second rolling member 54 rolls the bottom wall of the second template 22.
[0037] It should be noted that the first rotating drive member 51 and the second rotating drive member 52 can both be servo motors. The first rotating drive member 51 can drive the first rolling member 53 to roll the bottom wall of the first template 21, and by driving the first rolling member 53 to rotate, the first template 21 performs a first-stage bend on the sheet 60 to be folded. The second rotating drive member 52 can drive the second rolling member 54 to roll the bottom wall of the second template 22, and by driving the second rolling member 54 to rotate, the second template 22 performs a two-stage bend on the sheet 60 to be folded. The first rolling member 53 rolls with the first template 21, and the second rolling member 54 rolls with the second template 22, which can change the force positions of the first template 21 and the second template 22 when the bending drive member 50 is driven, ensuring that the first template 21 and the second template 22 always transmit a larger bending force, thereby ensuring the bending processing of the sheet 60 to be folded.
[0038] In one possible implementation, see Figure 3 One end of the first rolling member 53 is rotatably connected to a rotary rod 55 , and the rotary rod 55 is connected to the output end of the first rotary driving member 51 .
[0039] It should be noted that the rotating rod 55 is perpendicular to the first rolling member 53, and one end is connected to the output end of the first rotating driving member 51, which can drive the first rolling member 53 to perform circular motion, and can transmit the torque generated by the first rotating driving member 51 to the first rolling member 53, so that the first rolling member 53 can roll on the bottom wall of the first template 21 to realize the bending of the plate 60 to be folded.
[0040] In one possible implementation, see Figure 3 One end of the second rolling member 54 is rotatably connected to a crank 56 , and the crank 56 is connected to the output end of the second rotary driving member 52 .
[0041] It should be noted that the crank 56 can be an L-shaped rod. The first template 21 and the second template 22 are in the same plane when the sheet 60 to be folded is not bent. The second rotary driving member 52 is arranged on the first template 21. The crank 56 can prevent the surface of the first template 21 from affecting the circular motion of the second rolling member 54 when the second rotary driving member 52 drives the second rolling member 54, thereby ensuring that the second rolling member 54 can push the second template 22 to rotate through its own circular motion, thereby realizing the bending processing of the sheet 60 to be folded.
[0042] In one possible implementation, see Figure 3 The frame 10 is provided with an avoidance hole 12 , the bending movable die 20 is located above the avoidance hole 12 , and the bending driving member 50 is located below the avoidance hole 12 .
[0043] It should be noted that the second rotating drive member 52 can pass through the avoidance hole 12 under the driving action of the first rotating drive member 51. The avoidance hole 12 on the frame 10 enables the positioning mechanism 30 to cooperate with the bending drive member 50, so that the bending movable = fixed mold moves downward to press the sheet material 60 to be folded, and the bending movable mold 20 curls and bends the sheet material 60 to be folded upward, thereby realizing the bending processing of the sheet material 60 to be folded.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
