[0032] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0033] like Figure 1 and Figure 2 As shown, the bending and folding device includes a frame 101, a base plate 201 connected to the frame 101, a mounting plate 301 on the base plate 201, an upper die 401 at the bottom of the base plate 201, and a lower die 102 fixedly connected to the frame 101. The upper die 401 is located above the lower die 102, and a flipping die strip 103 is provided on one side of the lower die 102. The upper die 401 includes a main die strip 402 and a folding die assembly 403. A tool adjustment mechanism is provided on the mounting plate 301. The base plate 201 moves relative to the frame 101 to adjust the position of the upper die 401. When the sheet material is pressed by the upper and lower dies 102, the product is bent by rotating the flipping die strip 103. The upper die 401 can be length-adjusted by using the tool adjustment mechanism, thereby enabling the processing of different sheet materials to be bent.

[0034] like Figure 6 and Figure 7As shown, the tool adjustment mechanism includes a pneumatic cylinder 302, a first electric cylinder 307, and a second electric cylinder 308; a bearing seat 310 is fixedly connected to the mounting plate 301, and the bearing seat 310 is provided with a pin 311; a first mounting seat 305 and a second mounting seat 306 are respectively provided on both sides of the tool assembly 403, the second mounting seat 306 is fixedly connected to the mounting plate 301, and the pin 311 passes through the first mounting seat 305, the tool assembly 403, and the second mounting seat 306; the first electric cylinder 307 is fixedly connected to the first mounting seat 302. On one side, the second electric cylinder 308 is fixedly connected to the second mounting base 306. The second electric cylinder 308 is higher than the first electric cylinder 307. The upper end of the mounting plate 301 is provided with a hinge seat 309. The middle part of the cylinder 302 is hinged to the hinge seat 309. The cylinder 302 includes a piston rod 303. The first mounting base 305 is hinged with a connector 304. The end of the piston rod 303 is connected to the connector 304. The blade assembly 403 includes blade blocks 405. The blade blocks 405 are arranged in sequence. The end of the blade block 405 is provided with a limiting hole 406.The cylinder body of cylinder 302 is hinged to hinge seat 309, and the connector 304 is also hinged to the first mounting seat 305 to accommodate the angular rotation of the cylinder body and piston rod 303 during the extension and retraction of piston rod 303. When the blade assembly 403 is in the reset position, the limiting hole 406 is coaxial with the output end of the first electric cylinder 307. When the extension rod of the first electric cylinder 307 is inserted into the limiting hole 406, i.e., the blade block 405 is restricted, the cylinder 302 can pull the first mounting seat 305 by driving the piston rod 303. 05 and the blade assembly 403 move around the pin 311. When the first mounting base 305 and the blade assembly 403 rotate a certain distance, the first electric cylinder 307 and the second electric cylinder 308 will be in a coaxial state. The second mounting base 306 is provided with a through hole 313, and the telescopic rod of the second electric cylinder 308 can pass through the through hole 313 and extend into the limiting hole 406 of the blade block 405. The telescopic rods of the two electric cylinders feed and return in the limiting hole 406 of the blade block 405 respectively, so that the blade block 405 forms two parts, namely, respectively generated by the first electric cylinder 307. The telescopic rod and the telescopic rod of the second electric cylinder 308 restrict the movement of the blade assembly. Since the first mounting base 305 is connected to the cylinder 302 and can rotate around the pin 311, and the second mounting base 306 is fixed to the mounting plate 301, the blade assembly block 405 restricted by the first electric cylinder 307 is the blade assembly block 405 that participates in the blade assembly, while the blade assembly block 405 restricted by the second electric cylinder 308 is the blade assembly block 405 that does not participate in the blade assembly. Because the blade assembly block 405 that does not participate in the blade assembly is restricted by the telescopic rod of the second electric cylinder 308, this part of the blade assembly block 405 is in an inclined position and detached from the fixed base 202. To allow space for the contact area between the blade assembly block 405 and the main mold strip 402; after the above steps are completed, the mounting plate 301 moves horizontally so that the blade assembly block 405 and the main mold strip 402 come into contact to form the upper mold 401 structure of the required length. Therefore, according to the above structure and the assembly design of the blade assembly block 405, it is only necessary to control the extension distance of the extension rods of the two electric cylinders to form separate control of the limited number of blade assembly blocks 405, so as to achieve the purpose of adjusting the blade length and thus meet the pressing requirements of different widths of the plates to be bent.

[0035] like Figure 5As shown, a fixing base 202 is fixedly connected to the bottom of the substrate 201, and a limiting block 203 is provided at the end of the fixing base 202; a protrusion 204 is provided at the bottom of the fixing base 202, and a mounting groove 407 is provided at the top of the single module 404, with the top of the mounting groove 407 engaging with the protrusion 204; a connecting groove 408 is provided at the top of the cutting tool block 405, with a bevel 409 at one end of the connecting groove 408. The engagement of the mounting groove 407 and the protrusion 204 ensures that the main mold strip 402 is stably mounted on the fixing base 202. The limiting block 203 and the fixing base 202 are an integral structure, which limits the installation of the main mold strip 402; the connecting groove 408 is used to connect the cutting tool block 405 to the fixing base 202, and one end of it is designed as a bevel 409 to facilitate the engagement and disengagement of the cutting tool block 405 from the fixing base 202, improving the convenience of the cutting tool adjustment process.

[0036] like Figure 3 As shown, the main mold strip 402 includes individual modules 404, which are arranged sequentially. The sides of each individual module 404 have a stepped structure, and adjacent individual modules 404 are connected by snap-fit. The main mold strip 402 adopts a splicing structure, which facilitates adjusting the length of the main mold strip 402 by changing the number used according to production needs, thereby increasing the applicability of the device. The splicing structure also facilitates maintenance and replacement, reducing costs. The stepped design on the sides of the individual modules 404 ensures that the main mold strip 402 is seamless after assembly, allowing for precise and reliable length adjustment. It also increases the overall stability of the mold strip, making it less prone to flipping or sliding during bending production. Furthermore, the stepped design helps ensure a tighter fit between the mold strips, improving splicing accuracy and processing precision.

[0037] like Figure 2 As shown, a third drive motor 104 is provided on one side of the frame 101. The third drive motor 104 is connected to a drive shaft 118, and a drive gear 105 is fixedly connected to the end of the drive shaft 118. A toothed plate 106 is fixedly connected to one end of the flipping mold 103, and the drive gear 105 meshes with the toothed plate 106. In the above structure, the third drive motor 104 drives the meshing transmission of the drive gear 105 and the toothed plate 106 to rotate the flipping mold 103. When the product is clamped by the upper mold 401 and the lower mold 102, the rotation of the flipping mold 103 can realize the bending action of the product.

[0038] like Figure 1 and Figure 2As shown, a first drive motor 108 is provided on the top of the frame 101. The first drive motor 108 is vertically arranged. The output end of the first drive motor 108 is connected to a synchronous belt mechanism. The synchronous belt mechanism includes a driven wheel 112. The driven wheel 112 is connected to the base plate 201 by a vertical lead screw transmission mechanism 109. Vertical guide rails 107 are provided at both ends of the frame 101. The vertical guide rails 107 are vertically arranged, and the inner side of the base plate 201 cooperates with the vertical guide rails 107. In the above structure, the first drive motor 108 drives two lead screw transmission mechanisms through a pair of synchronous belts 110, thereby realizing the lifting process of the substrate 201, that is, the upper mold 401 can be lifted and lowered to meet the processing of products with different thicknesses; among them, the vertical lead screw transmission mechanism 109 is existing technology; the synchronous belt mechanism is designed with two sets, each set of synchronous belt mechanism includes a synchronous belt 110, a driving pulley 111 and a driven pulley 112, the two synchronous belts 110 are arranged in a staggered manner, and are synchronously driven by the output end of the first drive motor 108, thereby ensuring the consistency of the movement of the two lead screw transmission mechanisms and ensuring the stability of the lifting of the substrate 201; the lifting of the substrate 201 is also guided by the cooperation of the vertical guide rail 107 to reduce the movement resistance and ensure the accuracy of the lifting direction.

[0039] like Figure 3 As shown, a second drive motor 207 is provided at one end of the base plate 201. The second drive motor 207 is horizontally positioned and connected to the mounting plate 301 by a horizontal lead screw transmission mechanism 208. A horizontal guide rail 206 is provided on the base plate 201, and the inner side of the mounting plate 301 cooperates with the horizontal guide rail 206. The horizontal guide rails 206 are arranged in pairs. The above structure realizes the lateral horizontal movement of the mounting plate 301. The horizontal lead screw transmission mechanism 208 is existing technology. The two horizontal guide rails 206 guide the movement of the mounting plate 301. After the cutter is adjusted, the horizontal movement of the mounting plate 301 can drive the blade assembly module 403 to move to splice with the main mold strip 402, thus completing the blade splicing process.

[0040] like Figure 2 As shown, gears 114 are provided on both sides of the frame 101, and a rack 115 is provided at the end of the base plate 201. The rack 115 meshes with the gears 114, and the gears 114 are connected to a synchronous shaft 116, which is horizontally arranged. The first drive motor 108 moves the base plate 201 through a vertical lead screw transmission mechanism. The above structure, through the meshing of two pairs of gears 114 and rack 115, provides auxiliary support and guidance for the vertical movement of the base plate 201, which helps to ensure that the overall posture of the upper mold 401 is horizontal and the direction of movement is accurate after the upper mold 401 moves, thereby ensuring processing accuracy.

[0041] The thickness of the cutting tool block 405 is 7mm. The cutting tool block 405 is installed in a modular fashion, allowing for flexible combinations of individual modules 404 and cutting tool blocks 405 according to production needs, further expanding the applicability of non-standard product processing. The cutting tool block 405 features a stepped design on its side, which improves splicing stability. The 7mm thickness of the cutting tool block 405 provides it with sufficient strength to prevent damage and also facilitates diverse length adjustments of the upper mold 401 based on the number of cutting tool blocks used, thus enhancing its applicability.

[0042] like Figure 3 As shown, a cable chain 205 is provided on the top of the base plate 201, a bracket 312 is provided at one end of the mounting plate 301, and a protective cover 117 is provided above the third drive motor 104 and the first electric cylinder 307. The cable chain 205 can neatly arrange the cables in the groove, preventing them from getting tangled. When the cables are fixed in the groove of the cable chain 205, they will not shift or loosen due to equipment movement, ensuring stability and allowing the cables to adapt to the movement process. The bracket 312 can support the air source wiring harness of the cylinder 302, preventing it from sagging and affecting the movement of the components on the mounting plate 301. The protective cover 117 provides protection and dust protection for the third drive motor 104 and the first electric cylinder 307.

[0043] The specific operation process of the blade assembly is as follows: Based on production needs, determine the required number of blade assembly blocks 405. With all mechanisms in the reset state, the telescopic rod of the first electric cylinder 307 extends into all blade assembly blocks 405 along the limiting hole 406. Then, the cylinder 302 extends and retracts, pulling the first mounting base 305 and the blade assembly module 403 to rotate, causing the blade assembly blocks 405 to separate from the fixed base 202. When the first mounting base 305 drives the first electric cylinder 307 to a coaxial position with the second electric cylinder 308, the first mounting base 305 and the blade assembly module 403 are tilted at a certain angle. Based on the above-determined number of blade assembly blocks 405, the second electric cylinder 308 is activated, causing its telescopic rod to extend into the limiting hole of a portion of the blade assembly blocks 405. The hole 406 restricts the cutting block 405 that does not need to be assembled, and at the same time, the telescopic rod of the first electric cylinder 307 retracts accordingly as the telescopic rod of the second electric cylinder 308 extends in; then the cylinder 302 resets, causing the first mounting base 305 and another part of the cutting block 405 to reset and be installed on the fixed base 202. The cutting block 405 that participates in the assembling is reset accordingly as the cylinder 302 resets, and the second electric cylinder 308 restricts the cutting block 405 that does not need to be assembled; then the transverse screw drive mechanism operates to move the mounting plate 301 as a whole along the horizontal guide rail 206, and the cutting block 405 that participates in the assembling moves horizontally along the fixed base 202 to be assembled with the main mold strip 402, and the upper mold 401 is adjusted to the specified mold strip length.

[0044] This bending and die-jointing device, through the movement of cylinder 302 and two electric cylinders, controls the number of die-jointing blocks 405 in the die-jointing module 403, enabling the upper die 401 to be adjustable in length to meet the processing needs of bending products of different lengths and to meet the production of non-standard products. The device has a high degree of automation, saving the complex and tedious process of manually changing die strips, reducing the labor intensity of personnel, and improving the efficiency of bending processing. The die-jointing blocks 405 and the main die strip 402 adopt a splicing design, which is stable and reliable, ensuring the processing accuracy of the product. It is easy to adjust the upper die 401 to a specified length according to production needs, which helps to save mold development costs.

[0045] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
