[0037] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] like Figures 1 to 3 As shown, an embodiment of the present invention provides a bending processing device for bending a plate body, such as a copper-based soft plate, comprising a supporting mechanism 1, a bending component 2, a moving component 3 and an elastic component, wherein the supporting mechanism 1 comprises a lower die 11 and an upper die 12, wherein the upper die 12 is detachably arranged on the lower die 11; the bending mechanism 2 comprises a lower bending block 21 arranged on the lower die 11, and a plurality of cam pressing blocks 22 and a plurality of cams 23 respectively arranged along a first direction, wherein the cam pressing block 22 is slidably arranged on the upper die 12 along a second direction, a protrusion 221 is arranged on the cam pressing block 22, and a plurality of first grooves 211 are arranged at intervals along the first direction on the lower bending block 21, wherein the protrusion 221 and the first groove 211 extend respectively along a third direction, and the first direction, the second direction and the third direction are respectively perpendicular to each other, wherein the first direction is as shown in FIG. Figure 2 The direction indicated by the arrows ab, the second direction is Figure 2 The direction indicated by the arrow cd is shown, and the third direction is as follows Figure 2 In the direction indicated by the arrow ef shown; multiple cams 23 are rotatably arranged on the upper mold 12, each cam 23 acts on a cam pressing block 22, and the multiple cams 23 rotate simultaneously to drive the multiple cam pressing blocks 22 to slide toward the lower bending block 21 to the working position in sequence, so that the protrusions 221 on the multiple cam pressing blocks 22 are respectively extended into the multiple first grooves 211 to bend the copper-based soft board; the elastic component is arranged on the upper mold 12, and is configured to drive the multiple cam pressing blocks 22 to slide away from the lower bending block 21 to reset to the initial position.

[0039] The bending processing device in this embodiment is provided with a lower bending block 21 on the lower die 11, and a matching cam pressing block 22 and cam 23 on the upper die 12. After the upper die 12 is assembled and fixed on the lower die 11, the copper-based soft board is bent by the bending mechanism 2 with the cooperation of the elastic component. Specifically, under the rotation of the cam 23, the cam pressing block 22 slides toward the lower bending block 21 to the working position. During this process, the protrusion 221 on the cam pressing block 22 gradually extends into the first groove 211, and the copper-based soft board placed on the lower bending block 21 is pressed toward the first groove 211 by the protrusion 221 to process a bend on the copper-based soft board. After the bending operation is completed, the cam 23 can be turned back to its original position, and the cam pressing block 22 is reset to its initial position under the action of the elastic component. The bending mechanism 2 in this embodiment cooperates with the protrusions 221 on the multiple cam pressing blocks 22 and the multiple first grooves 211 on the lower bending block 21, and the multiple cams 23 rotate simultaneously to make the multiple cam pressing blocks 22 slide toward the lower bending block 21 in sequence. Then, during the bending operation, the protrusions 221 on the multiple cam pressing blocks 22 can bend the copper-based soft board at multiple positions in sequence, and bend the copper-based soft board into a wavy bending shape.

[0040] Alternatively, see Figure 2 and Figure 4 The cam pressing block 22 is annular, and a convex point 222 is arranged on the inner peripheral surface of the cam pressing block 22. The cam 23 is located on the inner side of the cam pressing block 22 and its outer edge slides against the convex point 222. A second groove 231 is arranged on the outer edge of the cam 23. When the cam 23 rotates to make the convex point 222 slide out of the second groove 231, the cam pressing block 22 slides toward the lower bending block 21 to the working position, and the protrusion 221 extends into the first groove 211. When the cam 23 rotates to make the convex point 222 slide into the second groove 231, the elastic component drives the cam pressing block 22 to return to the initial position. By means of the convex point 222 on the cam pressing block 22 slidingly abutting against the outer edge of the cam 23 and the convex point 222 slidingly cooperating with the second groove 231 arranged on the outer edge of the cam 23, when the cam 23 rotates to different angles, the convex point 222 on the cam pressing block 22 is located in the second groove 231 or abuts against the outer edge of the cam 23 outside the second groove 231, and then with the cooperation of the elastic component, the cam pressing block 22 can slide back and forth along the second direction between the working position and the initial position, and the protrusion 221 on the cam pressing block 22 can extend into the first groove 211 or retract to the outside of the first groove 211.

[0041] Alternatively, see Figure 4 and Figure 5The second groove 231 extends along the circumference of the cam 23, and along the first direction, the lengths of the second grooves 231 on the multiple cams 23 along the circumference of the cam 23 increase or decrease in sequence, so that when the multiple cams 23 rotate simultaneously, according to the different lengths of the second grooves 231 on each cam 23, the time for the protrusions 222 on the multiple cam pressing blocks 22 arranged along the first direction to slide in the corresponding second grooves 231 increases or decreases in sequence, so that when the multiple cams 23 rotate simultaneously, the multiple cam pressing blocks 22 slide toward the lower bending block 21 to the working position in sequence, and then the protrusions 221 thereon can be inserted into the corresponding second grooves 231 in sequence to bend the copper-based soft board into a wavy bending shape.

[0042] Alternatively, see Figure 4 and Figure 7 , two lower bending blocks 21 are arranged at intervals along the third direction, two protrusions 221 on each cam pressing block 22 are arranged at intervals along the third direction, the two protrusions 221 on each cam pressing block 22 correspond to the first grooves 211 on the two lower bending blocks 21 respectively, and the multiple protrusions 221 on the multiple cam pressing blocks 22 correspond to the multiple first grooves 211 on the multiple lower bending blocks 21 respectively. By providing two lower bending blocks 21 and two protrusions 221 arranged at intervals on each cam pressing block 22, on the one hand, the bending processing device in this embodiment can perform wave bending on two products at the same time, and on the other hand, it can also process two wave bends at different positions on the product at one time, thereby improving the working efficiency.

[0043] Alternatively, see Figure 4 and Figure 6 , a rotating shaft 24 is rotatably provided on the upper die 12, and a plurality of cams 23 are respectively circumferentially stopped on the rotating shaft 24. For example, a cross-section surface is provided on the rotating shaft, and a matching non-circular hole is provided on the cam corresponding to the rotating shaft, so that the cam circumferential stop sleeve can be provided on the rotating shaft, so that the plurality of cams can be arranged in sequence. However, it is not limited to this. In other embodiments, the plurality of cams can be integrated with the rotating shaft in advance, or the plurality of cams can be fixed on the rotating shaft in sequence by other means. One end of the rotating shaft 24 extends out of the upper die 12 and is provided with a handle 241. The rotating shaft 24 is rotated by operating the handle 241 so that the rotating shaft 24 drives the plurality of cams 23 to rotate, that is, the rotating shaft 24 rotates forward to drive the plurality of cams 23 to rotate clockwise with the axial direction of the rotating shaft 24 as the axis, or the rotating shaft 24 rotates forward to drive the plurality of cams 23 to rotate counterclockwise with the axial direction of the rotating shaft 24 as the axis, thereby driving the plurality of cam pressing blocks 22 to perform bending operations on the lower bending block 21, and the operation is simple and convenient.

[0044] Alternatively, see Figure 4 and Figure 6Two stop pins 122 are arranged at intervals on the surface of the upper mold 12 facing the handle 241. Along the radial direction of the rotating shaft 24, the two stop pins 122 are respectively located on both sides of the rotating shaft 24. When the cam block 22 slides to the working position, the handle 241 abuts against one stop pin 122 to stop the rotating shaft 24 from rotating in the forward direction. When the cam block 22 is reset to the initial position, the handle 241 abuts against the other stop pin 122 to stop the rotating shaft 24 from rotating in the reverse direction. By setting two stop pins 122, a protective effect is formed on the various components of the bending processing device, that is, the operating handle 241 is prevented from moving excessively, and the rotating shaft 24 is ensured to rotate within the working angle range, thereby avoiding damage to parts due to excessive rotation of the rotating shaft 24, and at the same time improving the working efficiency. The above structure cooperates with the handle 241 through two stop pins 122, so that the handle 241 is used to operate the rotating shaft 24 to rotate forward at different angles, thereby driving multiple cam pressing blocks 22 to slide toward the lower bending block 21 in sequence, and then the protrusions 221 on the multiple cam pressing blocks 22 can be sequentially extended into the corresponding second grooves 231 to bend the copper-based soft board into a wavy bending shape. At the same time, by rotating the handle 241 in the opposite direction at different angles, the elastic component can sequentially drive the multiple cam pressing blocks 22 to return to the initial position.

[0045] Optionally, during the bending operation of the bending processing device in this embodiment, the handle 241 is pressed against the stop pin 122 on one side of the rotating shaft 24 as the operation starting point. At this time, the protrusions 222 on the multiple cam pressing blocks 22 are respectively located at the starting edges of the second grooves 231 on the corresponding cams 23, and then the rotating shaft 24 is rotated in the positive direction by the handle 241, for example, the rotating shaft 24 rotates clockwise with its own axial direction as the axis. As the rotating shaft 24 rotates to different angles in sequence, the protrusions 222 on the multiple cam pressing blocks 22 slide out of the corresponding second grooves 231 in sequence in time sequence and then abut on the outer edge of the cam 23, so that when the rotating shaft 24 rotates to the corresponding angle, a corresponding cam pressing block 22 will slide toward the lower bending block 21 to the operating position, and the protrusion 221 thereon extends into the corresponding first groove 211 to bend the copper substrate soft board, thereby realizing that the protrusions 221 on the multiple cam pressing blocks 22 extend into the corresponding second grooves 231 in sequence in time sequence. The copper-based soft board is bent into a wave-bending shape; when all the cam pressing blocks 22 slide to the operating position, the copper-based soft board is subjected to a bending action. At this time, the handle 241 abuts against the stop pin 122 on the other side of the rotating shaft 24, and the rotating shaft 24 has also been rotated forward to the limit position and cannot continue to rotate forward; finally, the rotating shaft 24 is rotated in the opposite direction by the handle 241, for example, the rotating shaft 24 rotates counterclockwise with its own axial direction as the axis, and the multiple cams 23 rotate respectively and return to the initial position in turn. At this time, the rotating shaft 24 rotates in the opposite direction to the limit position and cannot continue to rotate in the opposite direction. In this process, based on the elastic force of the elastic component, the multiple cam pressing blocks 22 slide away from the lower bending block 21 and return to the initial position in turn. The convex points 222 on the multiple cam pressing blocks 22 slide into the second grooves 231 on the corresponding cams 23 respectively. At this point, one bending operation of the bending processing device is completed, and the above operation is repeated to realize cyclic bending processing of the copper-based soft board.

[0046] Alternatively, see Figure 3 and Figure 6 Limiting grooves 2411 are respectively provided on both side surfaces of the handle 241. When the cam pressing block 22 slides to the working position, that is, when the rotating shaft 24 rotates forward to the limit position, a stop pin 122 corresponds to the bottom of the limiting groove 2411 on one side of the handle 241 to stop the rotating shaft 24 from continuing to rotate forward. When the cam pressing block 22 is reset to the initial position, that is, when the rotating shaft 24 rotates reversely to the limit position, the other stop pin 122 corresponds to the bottom of the limiting groove 2411 on the other side of the handle 241 to stop the rotating shaft 24 from continuing to rotate reversely, thereby protecting various components of the bending processing device and improving working efficiency.

[0047] Alternatively, see Figure 4, a plurality of slide grooves 121 are arranged at intervals along the first direction on the upper mold 12, and the slide grooves 121 extend along the second direction, and a boss 223 is arranged on the cam pressing block 22, and the bosses 223 on the plurality of cam pressing blocks 22 are respectively slidably arranged in the plurality of slide grooves 121 in a one-to-one correspondence. By providing a plurality of slide grooves 121 and respectively slidingly cooperating with the bosses 223 on the plurality of cam pressing blocks 22, the stability of the cam pressing block 22 during sliding can be ensured, and the cam pressing block 22 can be prevented from shaking or deflecting, and the sliding operations of the plurality of cam pressing blocks 22 can be made to not interfere with each other, and then, according to the different lengths of the second grooves 231 on the plurality of cams 23, the plurality of cam pressing blocks 22 can slide toward the lower bending block 21 to the working position in sequence or slide away from the lower bending block 21 to the initial position in sequence according to their respective sequences.

[0048] Alternatively, see Figure 4 and Figure 5 , the upper mold 12 is provided with a receiving groove 124 through-through along the second direction, and a plurality of cams 23 and a plurality of cam pressing blocks 22 are respectively accommodated in the receiving groove 124. Optionally, along the third direction, a plurality of slide grooves 121 are provided on both side walls of the receiving groove 124, and bosses 223 are respectively provided on both side surfaces of the cam pressing block 22 along the third direction, and the two bosses 223 on the cam pressing block 22 are respectively slidably provided in the two slide grooves 121 on the both side walls of the receiving groove 124. By providing bosses 223 on both side surfaces of the cam pressing block 22 to slide with the slide grooves 121, the stability of the cam pressing block 22 when sliding is further enhanced, and the cam pressing block 22 is prevented from shaking or deflecting.

[0049] Alternatively, see Figure 3 and Figure 4 The upper mold 12 in this embodiment includes a guide block 126 and a support block 127 connected to each other along a first direction, a receiving groove 124 is provided on the surface of the guide block 126 facing the support block 127, one end of the rotating shaft 24 is rotatably penetrated in the support block 127, and the other end passes through the receiving groove 124 and the guide block 126 in sequence, and passes through the surface of the guide block 126 away from the support block 127 to be connected to the handle 241. The upper mold 12 is formed by the guide block 126 and the support block 127, which facilitates the assembly of the upper mold 12, and the rotating shaft 24, a plurality of cams 23 and a plurality of cam pressing blocks 22 are assembled on the upper mold 12 in an orderly manner.

[0050] Alternatively, see Figure 6, one of the lower die 11 and the upper die 12 is provided with a positioning pin 111, and the other is provided with a positioning hole 123, and the positioning pin 111 is penetrated in the positioning hole 123. When the upper die 12 is assembled on the lower die 11, the first groove 211 of the lower bending block 21 on the lower die 11 and the protrusion 221 of the cam pressing block 22 on the upper die 12 can be ensured to align through the positioning pin 111 and the positioning hole 123, so as to ensure the processing quality of the bending processing device. Optionally, a plurality of positioning pins 111 and positioning holes 123 are provided respectively, and each positioning pin 111 is correspondingly penetrated in a positioning hole 123.

[0051] Alternatively, see Figure 6 The lower mold 11 in this embodiment includes a lower mold support plate 113 and a lower mold fixing block 112 arranged on the lower mold support plate 113 , and the positioning pin 111 is arranged on the lower mold fixing block 112 .

[0052] Optionally, a positioning groove 1121 is provided on the lower mold fixing block 112, and the lower bending block 21 is accommodated in the positioning groove 1121. Two positioning grooves 1121 can be provided according to the number of the lower bending blocks 21, and each lower bending block 21 is accommodated in one positioning groove 1121.

[0053] Alternatively, see Figure 4 , the elastic component includes two groups of elastic members 3 arranged on the upper mold 12, and the elastic members 3 can be springs. Along the third direction, the two groups of elastic members 3 are respectively located on both sides of the cam pressing block 22, and each group of elastic members 3 is arranged in a V shape and is respectively connected to multiple cam pressing blocks 22 one by one, and the tip of the V shape is arranged along the third direction. By arranging each group of elastic members 3 in a V shape, it is convenient to arrange more cam pressing blocks 22 in a shorter length along the first direction, and there is a position on the upper mold 12 to install two groups of elastic members 3. By setting two groups of elastic members 3, each cam pressing block 22 is equipped with two elastic members 3, providing sufficient and symmetrical elastic force to the cam pressing block 22, ensuring that the cam pressing block 22 is quickly and stably reset to the initial position under the action of the elastic component.

[0054] Alternatively, see Figure 4 , two rows of mounting holes 125 are provided on the surface of the upper mold 12 facing away from the lower mold 11. Along the third direction, the two rows of mounting holes 125 are respectively located on both sides of the accommodating groove 124. Each row of mounting holes 125 is arranged at intervals along the first direction, and the two rows of elastic members 3 are respectively installed on the two rows of mounting holes 125 in a one-to-one correspondence. Along the third direction, connecting parts 224 are respectively provided on the outer surfaces of both sides of each cam pressing block 22. One end of each elastic member 3 is connected to the bottom surface of the mounting hole 125, and the other end is connected to a connecting part 224 on a cam pressing block 22. The connecting part 224 extends along the third direction, and the length of the connecting parts 224 on multiple cam pressing blocks 22 along the third direction is set according to the arrangement shape of each group of elastic members 3.

[0055] Alternatively, see Figure 5 , Figure 6 and Figure 8 The bending processing device of this embodiment also includes a locking mechanism 4, which includes a rotating member 41 and a pressing arm 42. One end of the rotating member 41 is rotatably connected to the lower mold 11, and the other end is rotatably connected to the pressing arm 42. The pressing arm 42 can press on the surface of the upper mold 12 away from the lower mold 11 to lock the upper mold 12 to the lower mold 11. By setting the locking mechanism 4, before the bending operation, the upper mold 12 is first positioned on the lower mold 11 through the cooperation of the positioning pin 111 and the positioning hole 123, and then the rotating part 41 and the pressing arm 42 are rotated to press the pressing arm 42 on the surface of the upper mold 12 away from the lower mold 11, so that the upper mold 12 and the lower mold 11 are locked along the second direction. When the bending mechanism 2 generates tension along the second direction during the bending operation, an interaction force opposite to the tension is formed between the pressing arm 42 and the surface of the upper mold 12 away from the lower mold 11, so that the pressing arm 42 of the locking mechanism 4 will be firmly locked on the upper mold 12 to form a lock, thereby preventing the upper mold 12 and the lower mold 11 from collapsing due to the tension generated by the bending operation.

[0056] Alternatively, see Figure 5 , Figure 6 and Figure 8 The pressing arm 42 and the rotating member 41 are connected by a pin to ensure strength; the surface of the pressing arm 42 pressing on the upper die 12 is the pressing surface 421, which is a plane. The above arrangement enables the tension generated by the bending mechanism 2 during the bending operation to be transmitted to the pin, that is, the pin is used to bear the interaction force in the second direction formed between the pressing arm 42 and the surface of the upper die 12 away from the lower die 11, and at the same time, the pressing surface 421 is a plane to ensure that the pressing arm 42 is stably and reliably pressed on the surface of the upper die 12 away from the lower die 11, thereby ensuring that the pressing arm 42 is firmly locked on the upper die 12 to form a lock.

[0057] Alternatively, see Figure 8 The end of the rotating member 41 away from the pressing arm 42 is provided with a rotating rod 411, and the rotating rod 411 is rotatably penetrated on the lower mold 11. With respect to the locking mechanism 4, the lower mold 11 and the upper mold 12 in this embodiment are respectively provided with cavities or grooves for the rotating member 41 to rotate and accommodate, so that the upper mold 12 can be locked to the lower mold 11 or the upper mold 12 and the lower mold 11 can be unlocked by operating the rotating member 41 and the pressing arm 42.

[0058] The bending processing device in this embodiment has the following operating steps: first, the copper-based soft board is placed on the lower bending block 21 on the lower die 11, and then the upper die 12 is positioned on the lower die 11, and the pressing arm 42 is locked on the upper die 12; next, the rotating shaft 24 is rotated forward from the initial position by operating the handle 241, and the protrusions 221 on the multiple cam pressing blocks 22 perform bending processing on multiple positions on the copper-based soft board in turn under the rotation of the rotating shaft 24, and when the rotating shaft 24 rotates forward to the handle 2 When 41 abuts against the stop pin 122, the protrusions 221 on the multiple cam pressing blocks 22 all extend into the corresponding first grooves 211 on the lower bending block 21, that is, the copper-based soft board is processed into a wavy bending shape at this time, and the pressure can be maintained for a certain period of time thereafter; finally, the rotating shaft 24 is rotated in the opposite direction by operating the handle 241, and the multiple cams 23 and the multiple cam pressing blocks 22 are reset to the initial positions in turn; at this time, the pressing arm 42 can be rotated to remove it from the upper mold 12, and then the upper mold 12 is removed to take out the copper-based soft board.
