DETAILED DESCRIPTION

[0035] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0036] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0037] Reference Figure 1-Figure 9As shown, a sheet metal bending processing equipment is provided, and the bending processing equipment includes: a loading conveyor belt 100, a bending table 102 and a unloading conveyor belt 101 which are arranged in parallel in sequence; a lower mold 103 is provided on the bending table 102 which can be raised and lowered in the vertical direction, and an upper mold 105 which can be raised and lowered through a bracket 104 and cooperates with the lower mold 103 for bending the sheet metal; wherein, the bending table 102 is provided with two sets of clamping and fixing mechanisms 200 which are rotatably connected to both sides of the lower mold 103 respectively and are used to fix the sheet metal located on the lower mold 103 during bending and rotate with the bending of the sheet metal to adapt to different bending angles.

[0038] When in use, the sheet metal material is placed on the parallel feeding conveyor belt 100. The sheet metal material is transported to the designated position of the bending table 102 through the movement of the feeding conveyor belt 100. When the sheet metal material reaches the bending table 102, the two sets of clamping and fixing mechanisms 200 start to work. The two sets of mechanisms are rotatably connected to the two sides of the lower die 103, respectively, and can clamp the sheet metal material to ensure that the sheet metal will not move or misalign during the bending process. The lower die 103 is in the initial position, and the upper die 105 is adjusted to a suitable height through the bracket 104 to prepare for the bending operation. The bending operation is started, and the upper die 105 descends and cooperates with the lower die 103 to bend the sheet metal material. At this time, the clamping and fixing mechanism 200 will rotate with the bending of the sheet metal to adapt to different bending angles to ensure the accuracy and stability of the bending. After the bending is completed, the upper die 105 rises back to the initial position, and the clamping and fixing mechanism 200 releases the sheet metal material. Subsequently, the unloading conveyor belt 101 is started to convey the bent sheet metal material to the next process or collection area. The clamping and fixing mechanism 200 can rotate with the bending of the sheet metal, ensuring the stability and accuracy of the sheet metal material during the bending process, thereby improving the processing quality. The equipment can adapt to sheet metal materials of different thicknesses and sizes, as well as different bending angle requirements, and has strong versatility and flexibility.

[0039] Reference Figure 6-Figure 7 As shown, the clamping and fixing mechanism 200 includes: a supporting slide bar 201, a spring 202, a rotating plate 203 and a fixed block 204; wherein, a supporting slide bar 201 with a movable end pointing vertically upward and fixedly connected to the lower mold 103 is fixedly provided in the bending table 102, a spring 202 is sleeved on the supporting slide bar 201, and two ends are respectively abutted against the top surface of the bending table 102 and the bottom surface of the lower mold 103, the side of the lower mold 103 is rotatably connected to the rotating plate 203, a connecting rod 206 with one end rotatably connected to the side of the rotating plate 203 is rotatably provided on the bending table 102, a slide bar 207 that can be raised and lowered in a vertical direction is provided on the rotating plate 203 through a linkage drive assembly 300, and a fixed block 204 in contact with the surface of the sheet metal is fixedly provided on the bottom surface of the slide bar 207.

[0040] In the above scheme, before the bending operation begins, the clamping and fixing mechanism 200 is in an initial state. At this time, the support slide bar 201 is vertically fixedly connected to the lower die 103, and the spring 202 is sleeved on the support slide bar 201, and the two ends are respectively in contact with the top surface of the bending table 102 and the bottom surface of the lower die 103, providing a certain elastic support for the rotating plate 203. When the sheet metal material is transported to the bending table 102, the linkage drive assembly 300 is adjusted to make the slide bar 207 descend, drive the fixed block 204 to contact the surface of the sheet metal, and achieve clamping and fixing. At this time, the spring 202 is compressed, providing a certain pre-tightening force for the rotating plate 203 to ensure the stability of the clamping. During the bending process, as the upper die 105 descends and the lower die 103 cooperates, the sheet metal material bends. At this time, the rotating plate 203 rotates with the bending of the sheet metal, and the connecting rod 206 plays a role in transmitting the rotational force.

[0041] Reference Figure 6-Figure 7 As shown, a conveyor belt 205 that contacts the sheet metal and is used to send out the sheet metal after bending is fixedly provided on the bottom surface of the slide bar 207 of the clamping and fixing mechanism 200 close to one side of the unloading conveyor belt 101.

[0042] In the above scheme, after the bending is completed, the slide bar 207 of the clamping and fixing mechanism 200 close to the side of the unloading conveyor belt 101 not only releases the sheet metal material, but also the conveyor belt 205 fixed on its bottom surface starts to work. The conveyor belt 205 runs at an appropriate speed to send the bent sheet metal material from the bending table 102 and directly transport it to the unloading conveyor belt 101 for the next process or collection.

[0043] Reference Figure 6-Figure 8 As shown, the linkage drive assembly 300 includes: a bending member that drives the upper die 105 to descend and cooperate with the lower die 103 to bend the sheet metal, and a driving member that drives the slide bar 207 to descend and drives the fixing block 204 to fix the sheet metal during bending.

[0044] In the above scheme, when the bending operation needs to be started, the bending part is first started. The upper die 105 is driven to descend, and the sheet metal is bent in cooperation with the lower die 103. At this time, the rotating plate 203 of the clamping and fixing mechanism 200 rotates with the bending of the sheet metal to ensure the accuracy and stability of the bending. After the bending is completed, the clamping and fixing of the sheet metal is released.

[0045] Reference Figure 7-Figure 8 As shown, the bending part includes: a first hydraulic rod 301 and a connecting block 302; the first hydraulic rod 301 is fixedly provided on the bracket 104, the output end of the first hydraulic rod 301 is vertically downward and fixedly connected to the connecting block 302, and the upper mold 105 is fixedly provided on the bottom surface of the connecting block 302.

[0046] In the above scheme, when the bending operation needs to be started, the first hydraulic rod 301 starts to work, and its output end moves vertically downward, driving the connection block 302 and the upper die 105 to descend together. At the same time or later when the bending part is started, the driving part also starts to work. It drives the slide bar 207 to descend, driving the fixed block 204 to contact the surface of the sheet metal, and realizes the clamping and fixing of the sheet metal. With the movement of the output end of the first hydraulic rod 301, the connection block 302 is driven to descend together. Since the upper die 105 is fixed to the bottom surface of the connection block 302, the upper die 105 also descends accordingly. The upper die 105 descends and cooperates with the lower die 103 to bend the sheet metal located between the two.

[0047] Reference Figure 7-Figure 9 As shown, the driving member includes: a driving rack 303, a driven gear 306 and a driven rack 307; wherein, the side of the connecting block 302 is fixedly provided with the driving rack 303, the side of the bracket 104 is rotatably provided with a driving gear 304 meshing with the driving rack 303, and the rotating shaft of the driving gear 304 is rotatably provided with a transmission gear 305 meshing with the driving gear 304 through a first rotating rod 308, the side of the sliding rod 207 is fixedly provided with a driven rack 307, and the rotating plate 203 is rotatably provided with a driven gear 306 meshing with the driven rack 307, and at the same time, the driven gear 306 meshes with the transmission gear 305 and is rotationally connected to the transmission gear 305 through a second rotating rod 309.

[0048] In the above scheme, when the first hydraulic rod 301 starts to work, it drives the connection block 302 to descend. The descent of the connection block 302 causes the active rack 303 to descend accordingly, and drives the active gear 304 meshing with it to rotate. The rotation of the active gear 304 drives the transmission gear 305 to rotate through the first rotating rod 308. Since the transmission gear 305 is meshed with the driven gear 306, the rotation of the transmission gear 305 drives the driven gear 306 to rotate. The rotation of the driven gear 306 causes the driven rack 307 meshing with it to descend in the vertical direction, thereby driving the slide bar 207 and the fixed block 204 to descend, and realize the clamping and fixing of the sheet metal. After the bending is completed, the first hydraulic rod 301 works in the reverse direction, driving the connection block 302 to rise and reset. At this time, the active rack 303 also rises accordingly, and through the transmission of the active gear 304, the transmission gear 305 and the driven gear 306, the driven rack 307, the slide bar 207 and the fixed block 204 also rise and reset. The meshing transmission of the rack and the gear ensures precise synchronization between the lifting and lowering of the slide bar 207 and the upper mold 105, thereby improving the accuracy of the bending operation. Due to the stability of the gear transmission, the slide bar 207 and the fixed block 204 can clamp the sheet metal more stably and reliably, thus avoiding movement or dislocation during the bending process.

[0049] Reference Figure 6As shown, a pressure sensor 208 electrically connected to the first hydraulic rod 301 is fixedly provided on the fixing block 204 .

[0050] When the slide bar 207 and the fixed block 204 descend to clamp the sheet metal, the pressure sensor 208 starts to monitor the clamping pressure of the fixed block 204 on the sheet metal. If the clamping pressure exceeds the preset value, the pressure sensor 208 will send a signal to the first hydraulic rod 301 to adjust the output force to maintain an appropriate clamping pressure. During the bending process, the pressure sensor 208 continuously monitors the change of the clamping pressure and sends an adjustment signal to the first hydraulic rod 301 as needed to ensure the stability and accuracy of the bending operation.

[0051] Reference Figure 1-Figure 5 As shown, a feeding mechanism 400 for automatic feeding is fixedly provided at the input end of the feeding conveyor belt 100, and the feeding mechanism 400 includes two groups of feeding parts respectively fixedly provided on two side surfaces of the feeding conveyor belt 100 away from each other and a control part for driving the two groups of feeding parts.

[0052] When it is necessary to load materials, the control unit starts to work and drives the two sets of loading parts to work together. The loading part picks up a sheet metal from the pile of sheet metal to be processed and places it on the loading conveyor belt 100. The loading conveyor belt 100 starts to transport the sheet metal to the bending area for bending processing. The introduction of the loading mechanism 400 realizes automatic loading of sheet metal, reduces manual intervention, and improves production efficiency.

[0053] Reference Figure 1-Figure 5 As shown, the loading parts include: a fixed frame 401, a support plate 402, a baffle 403 and a slider 409; wherein, the loading conveyor belt 100 is fixedly provided with a fixed frame 401, a support plate 402 is slidably provided in the fixed frame 401 through a slider 409, an anti-slip pad 404 is fixedly provided on the surface of the support plate 402 in contact with the sheet metal, and a baffle 403 which slides alternately with the support plate 402 is slidably provided on the bottom surface of the support plate 402 through the slider 409.

[0054] In the above scheme, in the preparation stage, the support plate 402 and the baffle plate 403 are respectively slidably arranged in the fixed frame 401 through the slider 409. The surface of the support plate 402 in contact with the sheet metal is fixedly provided with an anti-skid pad 404 to prevent the sheet metal from slipping. When unloading is required, the control component drives the support plate 402 and the baffle plate 403 to work in coordination. The support plate 402 slides forward, contacts and picks up the sheet metal; at the same time, the baffle plate 403 also slides forward, slides alternately with the support plate 402, clamps the sheet metal, and after picking up the sheet metal, the control component drives the support plate 402 and the baffle plate 403 to slide in the opposite direction, placing the sheet metal on the feeding conveyor belt 100. At this time, the anti-skid pad 404 can ensure that the sheet metal is stably transported on the feeding conveyor belt 100.

[0055] Reference Figure 1-Figure 5 As shown, the control component includes: a driving plate 405, a second hydraulic rod 406 and a connecting plate 407; wherein, the second hydraulic rod 406 is fixedly provided on the side of the fixing frame 401, the output shaft of the second hydraulic rod 406 is horizontally arranged and the top end is fixedly connected to the connecting plate 407, two groups of driving plates 405 are fixedly provided on the surface of the connecting plate 407, the support plate 402 and the baffle plate 403 are respectively provided with staggered first limiting grooves 408 and second limiting grooves 410, and the driving plate 405 is fixedly provided with a driving rod 411 which slides through the first limiting grooves 408 and the second limiting grooves 410 in sequence.

[0056] In the above scheme, when the support plate 402 and the baffle plate 403 need to be driven, the second hydraulic rod 406 starts to work, and its output shaft is extended and retracted to drive the connecting plate 407 and the driving plate 405 to move. The driving rod 411 on the driving plate 405 slides through the first limiting groove 408 of the support plate 402 and the second limiting groove 410 of the baffle plate 403 in sequence, thereby driving the support plate 402 and the baffle plate 403 to move in coordination. By adjusting the output force and extension speed of the second hydraulic rod 406, the clamping force and moving speed of the support plate 402 and the baffle plate 403 can be controlled to ensure the stability and accuracy of the sheet metal during the picking and placing process.

[0057] In summary, the present invention provides a sheet metal bending processing equipment. When in use, the sheet metal material is placed on the input end of the automatic feeding mechanism 400. The two groups of feeding parts of the feeding mechanism 400 start to work together through the drive of the control part. The second hydraulic rod 406 pushes the connecting plate 407, and then drives the support plate 402 and the baffle 403 to slide in the fixed frame 401 through the driving plate 405 and the driving rod 411. The support plate 402 and the baffle 403 slide alternately to stably transport the sheet metal material to the feeding conveyor belt 100. The feeding conveyor belt 100 transports the sheet metal material to the lower die 103 on the bending table 102. When the sheet metal material is transported to the lower die 103, the two groups of clamping and fixing mechanisms 200 start to work. The spring 202 on the support slide bar 201 provides initial pressure to keep a certain tension between the rotating plate 203 and the connecting rod 206. As the upper mold 105 descends, the active rack 303 on the side of the connecting block 302 meshes with the active gear 304, thereby driving the transmission gear 305 to rotate. The transmission gear 305 meshes with the driven gear 306 through the second rotating rod 309, driving the driven rack 307 to descend, thereby causing the slide bar 207 and the fixed block 204 to descend, fixing the sheet metal material on the lower mold 103. At the same time, the rotating plate 203 rotates as the sheet metal is bent to adapt to different bending angles. The first hydraulic rod 301 continues to drive the upper mold 105 to descend, and cooperates with the lower mold 103 to bend the sheet metal. During the bending process, the clamping and fixing mechanism 200 keeps the sheet metal fixed to ensure the accuracy and stability of the bending. The pressure sensor 208 monitors the pressure changes during the bending process to ensure the bending quality. After the bending is completed, the first hydraulic rod 301 drives the upper mold 105 to rise. At the same time, the conveyor belt 205 in the clamping and fixing mechanism 200 close to the side of the unloading conveyor belt 101 starts to work to deliver the bent sheet metal material.
