In addition, in order to ensure the size after processing, it is necessary to properly trim the edge of the substrate 101 before bending, so that the excess edge waste 103 is trimmed to obtain a substrate of a suitable size, and then the substrate 101 is bent to form the bent portion 102.

[0019] In order to enable those skilled in the art to better understand the present invention, and thus to more clearly define the scope of the present invention, the present invention is described in detail with respect to some specific embodiments of the present invention. It should be noted that the following are only some specific implementation methods of the present invention, which are only part of the embodiments of the present invention, wherein the specific and direct description of the relevant structure is only for the convenience of understanding the present invention, and each specific feature does not naturally and directly limit the scope of implementation of the present invention. The conventional selection and replacement made by those skilled in the art under the guidance of the present invention should be regarded as within the scope of the present invention.

[0020] like Figure 2-Figure 5 As shown, the present invention discloses a double-bending-edge cutting mold, including two left and right cutting module groups 1, each cutting module group 1 includes an upper die base 2, a push piece 21, a lower die base 3, a side clamping slide 32, and a cutting slide 33.

[0021] The push piece 21 is fixedly arranged on the upper die base 2 by means of bolts and extends downward, so that the up and down movement of the upper die base 2 can drive the push piece 21 to move up and down.

[0022] The lower die base 3 is located below the upper die base 2. A support member 31 is fixedly installed on the upper side of the lower die base 3 facing the other lower die base 3 by bolts. The other lower die base 3 is the lower die base 3 of another cutting module 1. A first support surface 311 is provided on the upper side of the support member 31, and a second support surface 312 is provided on the side away from the other support member 31. Before the substrate 101 is placed in the cutting module 1 for cutting, the first support surface 311 and the lower surface of the substrate 101 are abutted against each other, and the second support surface 312 and the side of the bending portion 102 facing the other bending portion 102 are abutted against each other.

[0023] The side clamp slide 32 is provided with a first cutting blade 321 . The side clamp slide 32 is slidably disposed on the lower die base 3 , and is driven by the push member 21 to slide close to the second support surface 312 when the push member 21 moves downward.

[0024] The cutting slide 33 is provided with a second cutting blade 331 . The cutting slide 33 is slidably disposed on the lower die base 3 , and is driven by the pushing member 21 to slide closer to the first cutting blade 321 when the pushing member 21 moves downward.

[0025] The pushing member 21 drives the side clamping slide 32 to slide in a direction opposite to that driving the cutting slide 33 to slide.

[0026] Before cutting, the substrate 101 is first bent on both sides to form Figure 1In the state shown in FIG. 1 , at this time, the two sides of the substrate 101 form a bent portion 102, and the bent portion 102 does not cut the edge waste 103 so that its height is higher. Figure 1 The substrate 101 in the state is placed on the first supporting surface 311 of each cutting module 1, so that the left and right sides of the lower surface of the substrate 101 are supported by the first supporting surface 311. In addition, by adjusting the setting, the spacing between the two second supporting surfaces 312 is the same as the spacing between the two bending parts 102, so that the two second supporting surfaces 312 can respectively abut the opposite sides of the two bending parts 102 to position them, that is, forming Figure 5 The upper die seat 2 then moves toward the lower die seat 3 so that the push member 21 first contacts the side clamp slide seat 32 downward, thus forming a Figure 6 The upper mold base 2 then continues to move downward to allow the push member 21 to move downward, thereby driving the side clamp slide 32 to approach the second support surface 312 to clamp the bending portion 102 between the second support surface 312 and the side clamp slide 32, and allowing the first cutting blade 321 to abut against the second support surface 312. At this time, the side clamp slide 32 is to the side of the push member 21 closest to the second support surface 312 and no longer slides toward the second support surface 312 during the subsequent downward movement of the push member 21, thus forming Figure 7 The second state shown in FIG. 1 is then formed, whereupon the upper die seat 2 continues to move downward so that the push member 21 contacts the cutting slide 33 downward, thus forming a Figure 8 In the third state shown in the figure, the upper die seat 2 continues to move downward to make the push member 21 move downward to drive the cutting slide 33 to slide, so that the second cutting head 331 approaches the first cutting head 321 from the side of the bending portion 102 away from the first cutting head 321, so that the edge waste 103 on the bending portion 102 is cut and removed under the shearing force of the first cutting head 321 and the second cutting head 331, that is, Fig. 9 The fourth state is shown.

[0027] Therefore, by first bending the substrate 101 to form Figure 1In this process, the bending deviations caused by the differences in the tensile strength, elongation, grain size, sparseness, etc. of the material are combined with the surplus edge waste 103 to form a bending portion 102 of uncertain height. However, it is necessary to ensure that the height of the bending portion 102 of uncertain height is greater than the actual height required in the end. Then, the connection position of the excess edge waste 103 and the retained bending portion 102 is determined under the condition of positioning the substrate 101 and the position of the bending portion 102, so that the first cutting head 321 and the second cutting head 331 are punched at the cutting position to cut and remove the excess edge waste 103. After cutting, the relative position of the bending portion 102 and the substrate 101 does not change in subsequent processing and use, so that the height of the retained bending portion 102 is guaranteed to be the actual height required in the end to achieve high-precision production requirements.

[0028] In addition, it also includes a mounting base 4, which is located below the two lower mold bases 3, and the two upper mold bases 2 are slidably arranged on the mounting base 4 along the left and right directions by setting a slide rail, so that the lower mold base 3 can adjust the distance between the two second supporting surfaces 312 by sliding left and right to adapt to the processing of substrates 101 of different lengths.

[0029] In other embodiments, only one lower mold base 3 may be slidably disposed on the mounting base 4 .

[0030] In addition, the mounting base 4 is provided with an adjustment mechanism 5 for driving the lower die base 3 to slide left and right. Specifically, the adjustment mechanism 5 includes a screw assembly 51 and a drive motor 52. The drive motor 52 drives the screw assembly 51 to work and drive the lower die base 3 to slide left and right.

[0031] The working principle of the screw assembly 51 is a mature technology and will not be elaborated here. The driving motor 52 adopts a servo motor for precise control.

[0032] In this embodiment, there are two adjustment mechanisms 5 , which respectively control the sliding movement of different lower die bases 3 .

[0033] In other embodiments, only one adjustment mechanism 5 may be used. However, a first thread and a second thread with opposite spiral directions need to be set on the screw assembly 51. The first thread and the second thread cooperate with different lower mold bases 3. Therefore, under the operation of the drive motor 52, the two lower mold bases 3 will synchronously slide in opposite directions to achieve the approach or distance of the two second support surfaces 312.

[0034] In other embodiments, when only one lower die base 3 is sliding, only one adjustment mechanism 5 may be provided to control the sliding of the sliding lower die base 3 .

[0035] Specifically, in the present embodiment, the pushing member 21 is provided with a first pushing inclined surface 211 at the lower side facing the second supporting surface 312, and a second pushing inclined surface 212 is provided at the lower side facing away from the second supporting surface 312, and the first pushing inclined surface 211 is inclined upwardly toward the second supporting surface 312 along the horizontal direction, and the second pushing inclined surface 212 is inclined downwardly toward the second supporting surface 312 along the horizontal direction; correspondingly, a third pushing inclined surface 322 parallel to the first pushing inclined surface 211 is provided at the upper side of the side clamp slide 32 facing away from the second supporting surface 312, so that the pushing member 21 faces downward and the side clamp slide 32 is close to the second supporting surface through the cooperation of the first pushing inclined surface 211 and the third pushing inclined surface 322. 312; correspondingly, the cutting slide 33 includes a driving part 333 and a cutting part 334 located on both sides of the side clamp slide 32, wherein the driving part 333 is located on the side of the side clamp slide 32 away from the second supporting surface 312, and the cutting part 334 is located on the side of the side clamp slide 32 facing downwardly of the second supporting surface 312, wherein the second cutting head 331 is arranged on the cutting part 334, and a fourth pushing inclined surface 332 parallel to the second pushing inclined surface 212 is arranged above the side of the driving part 333 facing the second supporting surface 312, so that the pushing member 21 faces downward and the second cutting head 331 is close to the first cutting head 321 through the cooperation of the second pushing inclined surface 212 and the fourth pushing inclined surface 332.

[0036] Specifically, the pushing member 21 in this embodiment is provided with a first positioning surface 213 on the side of the first pushing inclined surface 211 facing the second supporting surface 312, and the side clamp slide 32 is provided with a second positioning surface 323 on the side of the third pushing inclined surface 322 away from the second supporting surface 312. The first positioning surface 213 and the second positioning surface 323 are both vertical surfaces.

[0037] From the initial state to the first state, the first pushing inclined surface 211 approaches and contacts the third pushing inclined surface 322 downward. From the first state to the second state, the first pushing inclined surface 211 faces downward to gradually push the third pushing inclined surface 322 toward the second supporting surface 312 and finally separate. From the second state to the third state, the first positioning surface 213 and the second positioning surface 323 abut against each other to keep the side clamp slide 32 clamping the bending portion 102, and the second pushing inclined surface 212 approaches and contacts the fourth pushing inclined surface 332 downward. From the third state to the fourth state, the second pushing inclined surface 212 faces downward to gradually push the fourth pushing inclined surface 332 away from the second supporting surface 312.

[0038] In addition, a first reset member 6 is arranged between the side clamping slide 32 and the cutting slide 33 in this embodiment, and the first reset member 6 is used to drive the first cutting head 321 to reset and move in the direction away from the second supporting surface 312; a second reset member 7 is arranged between the cutting slide 33 and the lower mold base 3, and the second reset member 7 is used to drive the second cutting head 331 to reset and move in the direction away from the first cutting head 321 so that the first cutting head 321 and the second cutting head 331 are located on both sides of the second supporting surface 312.

[0039] So as to realize that after the cutting process is completed, during the process of the upper mold base 2 being reset upward, the side clamping slide 32 is automatically driven by the first reset member 6 to slide away from the second support surface 312 to release the clamping of the bending portion 102, and the cutting slide 33 is automatically driven by the second reset member 7 to slide so that the second cutting head 331 is away from the first cutting head 321, and the first cutting head 321 and the second cutting head 331 are respectively located on both sides of the second support surface 312 for the next cutting process.

[0040] Preferably, the side clamping slide 32, the cutting slide 33, the first cutting head 321 and the second cutting head 331 are all in the shape of long strips extending forward and backward to adapt to the length of the bending portion 102; and the bending portion 102 is effectively clamped and cut by the side clamping slide 32, the cutting slide 33, the first cutting head 321 and the second cutting head 331 that are adapted to the length of the bending portion 102.

[0041] Preferably, there are multiple first reset members 6 and second reset members 7, which are arranged at intervals along the length direction of the cutting slide 33; so that a more uniform reset force in the length direction can be achieved through the multiple first reset members 6 and second reset members 7 arranged at intervals, and the structure is more orderly and compact.

[0042] Combination Fig.10 As shown, preferably, the first reset member 6 includes a connecting guide rod 61 and a reset spring 62, a mounting through hole 3331 is provided on the driving portion 333, the connecting guide rod 61 is penetrated in the mounting through hole 3331, and one end facing the side clamp slide 32 is connected to the side clamp slide 32, and one end away from the side clamp slide 32 is provided with a butt joint 63, the reset spring 62 is sleeved on the connecting guide rod 61, and one end abuts against the butt joint 63, and the other end abuts against the driving portion 333 to drive the side clamp slide 32 to reset. The guide sliding is achieved through the cooperation between the connecting guide rod 61 and the mounting through hole 3331, and the sliding of the side clamp slide 32 is driven more smoothly, and the reset spring 62 is sleeved on the connecting guide rod 61, and the two ends of the reset spring 62 respectively abut against the joint 63 and the driving portion 333 to provide a reset force to realize the reset of the side clamp slide 32 in the direction away from the second supporting surface 312.

[0043] Preferably, the second reset member 7 adopts a nitrogen spring, and the lower mold base 3 is provided with a mounting portion 71 on the side of the driving portion 333 away from the cutting portion 334, the second reset member 7 is arranged on the mounting portion 71, and one end of the second reset member 7 is connected to the cutting portion 334 to drive the cutting slide 33 to reset.

[0044] Preferably, there are multiple push members 21, which are arranged along the length direction of the side clamp slide 32, and the push members 21 and the first reset members 6 are arranged at intervals, so that more uniform pushing and resetting in the length direction can be achieved through the multiple first reset members 6 and push members 21 arranged at intervals, and the structure is more orderly and compact.

[0045] In addition, a top pressure plate 22 with vertical sliding movement is provided at the lower end of the upper mold base 2 in this embodiment, and a guide rod is used for sliding guidance. The top pressure plate 22 is used to contact the upper surface of the substrate 101 before the side clamp slide 32 and the second supporting surface 312 clamp the bending portion 102 or when the side clamp slide 32 and the second supporting surface 312 clamp the bending portion 102 to clamp the substrate 101 between the first supporting surface 311 and the top pressure plate 22.

[0046] Specifically, in the initial state, there is a certain distance between the top pressure plate 22 and the upper surface of the substrate 101. From the initial state to the third state, the top pressure plate 22 faces downward and finally contacts the upper surface of the substrate 101. In addition, it should be noted that if the substrate 101 is placed deviated in the initial state, causing the lower surface of the substrate 101 to be higher than the first supporting surface 311 to produce a certain distance, the top pressure plate 22 contacts the upper surface of the substrate 101 before reaching the third state, and pushes the substrate 101 downward so that the bending portion 102 is synchronously driven downward to the corresponding position, thereby ensuring the accuracy of the cutting position.

[0047] Preferably, a third reset member 8 is provided between the top pressure plate 22 and the upper die base 2, and specifically a nitrogen spring is adopted.

[0049] In addition, the upper mold base 2 and the lower mold base 3 use a multi-piece guide assembly 9 for vertical sliding guidance, so that the overall cutting mold group 1 can move synchronously during the left and right sliding adjustment of the lower mold base 3, so as to prevent the sliding adjustment from causing the push piece 21 and the side clamping slide 32, and the cutting slide 33 to be offset and unable to clamp, unable to cut, and motion interference.

[0050] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
