[0027] Compared with the prior art, the lamp fitting processing and bending device of the present invention has the following beneficial effects:

[0028] First, the processing method of fixing the bending degree of the long strip accessories of existing lamps cannot meet the diverse usage requirements of various types of lamps and lamps in different application places, which greatly limits the application scope of the bending equipment and reduces its adaptability and versatility in lamp production. The present invention can accurately and flexibly adjust the bending degree of the first template through the coordinated operation mechanism of the driving wheel, the first driving rod, the first slide groove and other components. At the same time, with the rapid replacement of the second template assembly with the corresponding bending degree, it can realize the all-round and diversified bending processing of the long strip accessories. The present invention breaks the constraints of the traditional fixed bending mode and gives the bending equipment more complete adaptability and versatility. Whether it is a very creative niche lamp or a large-scale mass-produced conventional lamp, the ideal bending processing effect can be achieved with the help of this equipment. It not only broadens the application field of the bending equipment, but also significantly improves the ability of lamp manufacturers to respond to the diversified market needs.

[0029] Second, in the bending process of long strip accessories of lamps, if the symmetry of the bending cannot be ensured, it is very easy to cause the overall appearance of the lamp to be unbalanced, seriously affecting its aesthetic value and product quality. In particular, for those high-end lamps with extremely high requirements for styling design, the symmetrical bending process is a key factor in the success or failure of the product. When adjusting the bending degree of the left and right free ends of the first template, the present invention uses the precise coordination of the first cylinder, the drive plate, the second slide groove, the first drive rod and other components. Only a single driving force, the first cylinder, is required to achieve symmetrical bending adjustment of the two side ends of the first template. The present invention can meet the requirements of symmetrical bending processing and ensure that the first template always maintains a left-right symmetrical shape after the bending degree is adjusted. This can ensure that the symmetry of the bending points is accurately guaranteed when bending at the first template in the subsequent process, so that the bending arc reaches a high-precision symmetrical standard, thereby greatly improving the overall aesthetics and quality of the lamp, and fully meeting the stringent requirements of the high-end lamp market for exquisite product appearance.

[0030] 3. During the bending process, if the fit between the bending mold and the accessories is poor, the shape of the processed lamp accessories will be irregular, which will not only affect the product quality, but also cause many inconveniences in subsequent installation and use. The present invention provides a second connecting seat, a slot, an insert, a first positioning pin and other components, which can easily replace the corresponding arc-shaped second template to achieve a perfect match with the curvature of the first template. That is, the present invention can adapt to the replacement of arc components and improve the bending and fitting accuracy. The long strip accessories bent between the first template and the second template can fit tightly against the inner side walls of the two, completing a high-fit bending process, effectively ensuring that the shape of the processed lamp accessories is accurate and correct, and the surface is smooth and flat, significantly reducing defects and defective rates caused by fitting problems, and greatly improving product quality and production efficiency.

[0031] Fourth, after the traditional bending process is completed, the bent accessories are often stuck in the mold cavity, making it difficult to remove them smoothly and enter the subsequent operation link, which not only seriously affects the processing efficiency, but may also cause damage to the accessories due to forced removal, increasing production costs; the present invention provides a third cylinder, a first guide seat and other components, which can quickly lift the long strip accessories upward after the bending is completed, helping them to smoothly separate from the first template and the second template area; the present invention can cleverly lift the bent accessories, smooth the processing flow, and effectively avoid the interference of the bent long strip accessories in the inner cavities of the first template and the second template, ensuring that they can be smoothly pushed to the right and enter the next processing flow, effectively ensuring the continuity of the processing flow, greatly improving the overall processing efficiency, and reducing the loss of accessories and production costs caused by interference;

[0032] 5. During the movement of lamp accessories, if there is a lack of effective guiding and limiting measures, the accessories are very likely to deviate and jam, which in turn affects processing accuracy and efficiency. The present invention cleverly arranges a mounting frame and guide wheels at the first guide seat, which can accurately guide and limit the elongated accessories to ensure smooth movement. On the one hand, they can accurately guide and limit the position of the elongated accessories in the inner cavity of the first guide seat, ensuring that the elongated accessories always move stably along the predetermined path; on the other hand, they can also assist the elongated accessories in sliding smoothly to the right. Compared with the method of the elongated accessories directly adhering to the side wall of the first guide seat, the friction force is greatly reduced, the jamming phenomenon is reduced, the processing stability and accuracy are significantly improved, and the efficient advancement of the processing process is effectively guaranteed.

[0033] 6. In multi-point continuous bending processing, if the positions of the various components are not coordinated, the lamp accessories will not be able to accurately enter the bending area, seriously affecting the continuity and accuracy of the processing; the present invention is provided with a first motor, a lead screw, and a movable seat, which can accurately translate the front and rear position of the movable platform relative to the workbench; the present invention can accurately translate and adjust the position to ensure smooth multi-point bending, thereby ensuring that the first guide seat and the bending space between the second template and the first template after the bending degree is adjusted are accurately aligned, ensuring that the long strip accessories can smoothly enter the second template and the first template cavity along the guidance of the first guide seat, creating the necessary conditions for multi-point continuous bending processing of the long strip accessories, greatly improving the success rate and efficiency of the processing, and fully meeting the process requirements of complex lamp shapes for multi-point bending;

[0034] 7. The existing bending processing of long strip accessories mostly relies on manual feeding. However, manual feeding is greatly affected by human factors and the accuracy is difficult to control. This directly leads to uneven spacing between points after multi-point bending processing, seriously affecting the accuracy and aesthetics of the processing, and cannot meet the strict requirements of high-end lamps for details and quality; the present invention is provided with an intermittent automatic feeding function for long strip accessories. With the help of the close coordination of the first rotating rod, the first bevel gear, the second bevel gear, the second rotating rod and other components, the fan-shaped drive plates corresponding to the front and rear positions can be synchronized and rotated in opposite directions at the same time. When the fan-shaped drive plates rotate to the position corresponding to the long strip accessories, the fan-shaped drive plates rotate in opposite directions. When the side walls of the parts are in contact, the continuously rotating fan-shaped driving plate will accurately push the long strip accessories to the right. When the fan-shaped driving plate is separated from the side wall of the long strip accessories, the equipment will bend the corresponding points of the long strip accessories. The automatic feeding of the present invention is accurate and efficient, ensuring uniform spacing. Compared with manual feeding, this automatic interval pushing function has greatly improved the accuracy, which can effectively ensure the equidistant spacing of adjacent bending points of subsequent long strip accessories, making the lines of the long strip accessories after bending more regular and smooth, greatly improving the accuracy and aesthetics of lamp accessories, and fully meeting the high-quality product requirements of the high-end lamp market.

[0035] 8. Different lamp designs have different requirements for the bending spacing of lamp accessories. Traditional processing methods are difficult to meet such diverse needs, which greatly limits the innovation and development space of lamp design. The present invention provides two sets of fan-shaped drive plates with different arc lengths, and the two sets of fan-shaped drive plates can selectively contact the side walls of the long strip accessories according to actual needs, thereby realizing intermittent pushing of the long strip accessories at different travel distances. The present invention has flexible and diverse adjustments for the use of the fan-shaped drive plates to meet diverse processing needs. It can flexibly and accurately adjust the spacing between adjacent bending points of the long strip accessories according to the processing needs of different lamp accessories. Whether it is closely arranged small lamp accessories or large lamp components with larger spacing, it can be perfectly adapted, greatly enhancing the adaptability of the equipment to different bending processing requirements, and providing diversified processing needs for the bending processing of lamp production.

[0036] 9. In traditional equipment, switching between different functional components often requires complex operations and the support of multiple driving forces, which not only increases the complexity and cost of the equipment, but also seriously reduces the debugging and processing efficiency. The present invention has an ingenious adjustment design for the two sets of fan-shaped drive plates. The position conversion of the two sets of fan-shaped drive plates can be easily achieved only by rotating the second drive rod. When one set of fan-shaped drive plates is close to the side wall of the long strip accessory, the other set of fan-shaped drive plates automatically moves away from the side wall of the long strip accessory, ensuring that only one set of fan-shaped drive plates is always pushing the side wall of the long strip accessory. The present invention adopts a convenient adjustment and switching mechanism to greatly improve the processing efficiency. The position conversion of the two sets of fan-shaped drive plates is achieved by rotating the second drive rod of the same component. No additional driving force is required, which simplifies the equipment operation process, greatly shortens the overall debugging time of the bending equipment, and significantly improves the overall efficiency of the bending process, making the production of lamp accessories more efficient and convenient, and effectively reducing production costs.

[0037] 10. If the adjusted components become loose during operation, the feeding will be unstable, seriously affecting the processing accuracy and product quality. The present invention provides a precise positioning function for the second driving rod after rotation. Through the fixing plate, positioning hole, positioning plate and other components, the second driving rod and the second positioning pin after rotation can be firmly locked and positioned. The present invention adopts a stable positioning and locking mechanism to ensure stable and reliable feeding. The fan-shaped driving plate after adjusting the position can stably contact the side wall of the long strip accessory. There will be no loosening in the subsequent driving process of the long strip accessory to move, which provides a solid and reliable guarantee for accurate feeding, further improves the stability and accuracy of the processing, ensures the high-quality completion of the bending process, and reduces the defective rate and production cost caused by loose components.

[0038] 11. During the pushing process of the lamp accessories, if the front and rear forces are uneven, the accessories are very likely to tilt or deflect, seriously affecting the accuracy and continuity of the processing; the present invention provides an adjustment conversion function for the front and rear two sets of fan-shaped drive plates to ensure that the front and rear two sets of fan-shaped drive plates are adjusted accordingly, ensuring that the two fan-shaped drive plates with the same arc length are adjusted to the front and rear side walls of the long strip accessories respectively; the front and rear two sets of fan-shaped drive plates of the present invention adopt a synchronous adjustment strategy to ensure horizontal and stable movement. In the subsequent pushing process, the front and rear side walls of the long strip accessories are pushed by the fan-shaped drive plates with the same arc length, ensuring that the front and rear forces of the long strip accessories are consistent during the pushing process, thereby ensuring that the long strip accessories always move stably in the horizontal direction, effectively avoiding the deviation or jamming caused by uneven force, improving the stability and accuracy of the processing process, and laying a solid foundation for high-quality bending processing;

[0039] 12. When conventional long strip lamp accessories are subjected to continuous multi-point bending processing, a series of tedious steps such as disassembly, pushing and displacement, repositioning, and bending need to be performed manually in sequence. This operation process is not only inefficient and difficult to achieve continuous and equidistant bending processing, but also prone to errors introduced by multiple manual clamping and positioning, resulting in unstable product quality and a significant increase in production costs. The present invention realizes the automated processing of continuous multi-point bending, eliminating the need for manual execution of tedious steps such as disassembly, pushing and displacement, and repositioning, and can directly perform continuous multi-point bending processing on long strip lamp accessories. It greatly improves processing efficiency and fully meets the urgent need for multi-point bending in complex lamp shapes. It can accurately achieve continuous and equidistant bending operations according to the preset intervals, providing a strong guarantee for the production of lamps with regular shapes and smooth lines, effectively improving the overall aesthetics and standardized production level of lamps. At the same time, it reduces multiple manual clamping and positioning links, avoids errors introduced by manual operations, and effectively guarantees bending processing accuracy with the help of automation and high-precision positioning systems, thereby improving the overall quality of lamp accessories, reducing the defective rate, and reducing material waste and cost increases caused by precision issues.

[0040] In summary, the present invention has significant advantages in the field of bending processing of long strip accessories for lamps: first, it can flexibly adjust the degree of bending, and realize diversified bending in conjunction with component replacement, thereby enhancing the applicability and versatility of bending equipment, broadening its scope of application, and helping enterprises to cope with diverse market demands and enhance competitiveness; in terms of bending technology, the present invention can achieve precise and symmetrical bending, ensure the symmetry of accessories after bending, enhance the aesthetics and quality of lamps, and meet the needs of high-end markets; with the help of convenient arc-shaped component replacement, the accessories are closely fitted to the mold, reducing the defective rate, and improving product quality and production efficiency; in the processing flow, the present invention cleverly holds up the accessories after bending to avoid interference, ensure process continuity, improve efficiency and reduce losses; through precise guide limiting, ensure smooth sliding of accessories movement, improving processing stability and accuracy; precise translation adjustment mechanism, coordinating component positions, creating conditions for multi-point continuous bending, and improving processing success rate and efficiency; in the feeding link, intermittent automatic feeding is adopted to ensure that the spacing between bending points is equidistant, improving the accuracy and aesthetics of accessories, and the bending spacing can be flexibly adjusted to meet diverse processing needs; in terms of operation and debugging, the convenient adjustment switching mechanism simplifies the process, shortens the debugging time, and improves processing efficiency; the adjustment components are firmly positioned to ensure stable feeding, and the feeding components are adjusted synchronously to ensure that the accessories move horizontally and stably; in addition, the present invention realizes continuous multi-point bending automated processing, abandons the disadvantages of manual operation, improves efficiency, ensures bending accuracy, and improves the overall beauty and standardized production level of lamps.

DETAILED DESCRIPTION

[0050] The following is a combination of specific implementation cases and attached Figures 1 to 8 The present invention is further described below, but the present invention is not limited to these embodiments.

[0051] See Figures 1 to 8 As shown, a device for processing and bending lamp accessories is shown. In this embodiment, a long strip lamp pole is used as an example to illustrate the bending process of lamp accessories. The device includes a workbench 1, on which a first mold assembly 2 and a second mold assembly 4 are provided. The bending process of the lamp accessories is achieved through the cooperation of the first mold assembly 2 and the adjustment unit 3. The first mold assembly 2 includes a first template 2004. The middle part of the first template 2004 is fixedly mounted on the upper surface of the workbench 1. For details, see Figure 1 As shown, a vertical support base 2001 is vertically mounted on the upper surface of the workbench 1, a horizontal support base 2002 is vertically mounted on the rear side of the vertical support base 2001, a first connecting base 2003 is fixedly mounted on the rear side of the horizontal support base 2002, and the first connecting base 2003 is fixedly connected to the middle part of the side wall of the first template 2004. The bending curvature of the first template 2004 is adjusted by the adjustment unit 3, thereby achieving the change of the bending curvature of the first template 2004;

[0052] Main references Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the adjustment unit 3 includes two first chutes 3001 that are inclined and symmetrically opened on the workbench 1, and the first driving rods 3002 are respectively slidably embedded in the two first chutes 3001. The two first driving rods 3002 are respectively fixedly installed with driving wheels 3003. The side walls of the driving wheels 3003 are arranged in contact with the side walls of the first template 2004. A first cylinder 3005 is fixedly installed on the lower surface of the workbench 1, and the output end of the first cylinder 3005 is connected to the driving plate 3004. The left and right ends of the driving plate 3004 are respectively provided with second chutes 3006. The first driving rods 3002 are slidably embedded in the inner cavities of the second chutes 3006 at the corresponding positions.

[0053] The first cylinder 3005 is turned on to drive the driving plate 3004 to move backward, at which time the two sets of first driving rods 3002 are prompted to move along the inner cavities of the first slide grooves 3001 at corresponding positions, so as to prompt the left and right sets of driving wheels 3003 to move backward synchronously. Since the middle part of the first template 2004 is fixedly connected to the horizontal support seat 2002, when the left and right ends of the first template 2004 are driven backward by the two sets of driving wheels 3003, the left and right ends of the first template 2004 are prompted to bend backward synchronously, prompting the first template 2004 to form an arc shape. By adjusting the displacement distance of the two sets of driving wheels 3003, the first template 2004 can be bent into an arc mold to different degrees.

[0054] The present invention can accurately and flexibly adjust the bending degree of the first template 2004 through the coordinated operation mechanism of the driving wheel 3003, the first driving rod 3002, the first slide 3001 and other components; the present invention breaks the constraints of the traditional fixed bending mode and gives the bending equipment more complete adaptability and versatility. Whether it is a very creative niche lamp or a large-scale mass-produced conventional lamp, the device can achieve an ideal bending processing effect, which not only broadens the application field of the bending equipment, but also significantly improves the ability of lamp manufacturers to respond to diversified market demands; when adjusting the bending degree of the left and right free ends of the first template 2004, the present invention uses the first air The precise coordination of the cylinder 3005, the drive plate 3004, the second slide groove 3006, the first drive rod 3002 and other components only requires a single driving force, the first cylinder 3005, to achieve symmetrical bending adjustment of the two side ends of the first template 2004; the present invention can meet the needs of symmetrical bending processing, and can ensure that the first template 2004 after the bending degree is adjusted always maintains a left-right symmetrical shape, which can ensure that the symmetry of the bending points is accurately guaranteed when bending at the first template 2004 later, so that the bending processing arc reaches a high-precision symmetrical standard, thereby greatly improving the overall aesthetics and quality of the lamp, and fully meeting the stringent requirements of the high-end lamp market for the exquisite appearance of products.

[0055] In addition, the main reference Figure 4 As shown, mounting blocks 3007 are installed correspondingly at the front and rear ends of the lower surface of the workbench 1, and a limiting rod 3008 is vertically installed between the two corresponding mounting blocks 3007; wherein, the driving plate 3004 is slidably sleeved on the limiting rod 3008. When the driving plate 3004 is moved by force, the moving direction of the driving plate 3004 can be guided and limited by the limiting rod 3008, ensuring that the driving plate 3004 will not deviate when moving in the front and rear directions, thereby ensuring that the left and right ends of the first template 2004 are subjected to the same force when being driven.

[0056] Main references Figures 1 to 3 As shown, the second mold assembly 4 includes a second cylinder 4001, a mounting base 4002 is installed at the output end of the second cylinder 4001, a second connecting base 4003 is installed on the front side of the mounting base 4002, a slot 4004 is opened on the upper surface of the second connecting base 4003, an insert block 4005 is slidably inserted into the slot 4004, a first locating pin 4006 is threadedly provided on the rear side wall of the second connecting base 4003, and the output end of the first locating pin 4006 is threadedly embedded in the side wall of the insert block 4005, and a second template 4007 is installed on the front side of the insert block 4005;

When the fan-shaped driving plates 7013 close to the side walls of the long strip accessories 9 on the two second rotating rods 7007 rotate to fit the side walls of the long strip accessories 9, the fan-shaped driving plates 7013 that continue to rotate apply a rightward thrust to the side walls of the long strip accessories 9, causing the long strip accessories 9 to move one unit to the right along the inner cavity of the first guide seat 6002 until the fan-shaped driving plates 7013 are separated from the side walls of the long strip accessories 9, thereby realizing intermittent pushing of the long strip accessories 9 to the right.

Based on this principle, the relative positions of the front and rear fan-shaped driving plates 7013 are adjusted to ensure that the two fan-shaped driving plates 7013 with the same arc length are at the same distance from the side wall of the long strip accessory 9. The second positioning pin 7018 is screwed back into the corresponding positioning hole 7022 to achieve the locking of the positions of the rotation shaft 7016 and the second driving rod 7019 after the rotation adjustment. By adjusting the positions of the two groups of fan-shaped driving plates 7013 with different arc lengths, it is ensured that the two groups of fan-shaped driving plates 7013 can selectively contact the side wall of the long strip accessory 9 according to actual needs, thereby achieving intermittent pushing of the long strip accessory 9 at different travel distances.

[0073] The present invention provides a precise positioning function for the second driving rod 7019 after rotation, and can firmly lock and position the second driving rod 7019 and the second positioning pin 7018 after rotation through the fixing piece 7021, the positioning hole 7022, the positioning piece 7017 and other components; the present invention adopts a stable positioning locking mechanism to ensure stable and reliable feeding, and the fan-shaped driving plate 7013 after adjusting the position can stably contact the side wall of the long strip accessory 9, and will not loosen during the subsequent driving process of the long strip accessory 9 to move, providing a solid and reliable guarantee for precise feeding, further improving the stability and accuracy of the processing, ensuring high-quality completion of the bending processing, and reducing the defective rate and production cost caused by loose components; and the front and rear groups are fixed. The fan-shaped drive plates 7013 are all provided with an adjustment conversion function to ensure that the front and rear groups of fan-shaped drive plates 7013 are adjusted accordingly, ensuring that the two fan-shaped drive plates 7013 with the same arc length are adjusted to the front and rear side walls of the long strip accessory 9 respectively; the front and rear groups of fan-shaped drive plates 7013 of the present invention adopt a synchronous adjustment strategy to ensure stable horizontal movement. In the subsequent pushing process, the front and rear side walls of the long strip accessory 9 are pushed by the fan-shaped drive plates 7013 with the same arc length, ensuring that the front and rear forces of the long strip accessory 9 are consistent during the pushing process, thereby ensuring that the long strip accessory 9 always moves stably in the horizontal direction, effectively avoiding offset or jamming caused by uneven force, improving the stability and accuracy of the processing process, and laying a solid foundation for high-quality bending processing.

[0074] In addition, the present invention realizes the automated processing of continuous multi-point bending, without the need for manual execution of tedious disassembly, pushing displacement, re-positioning and other steps. It can directly perform continuous multi-point bending processing on long strip lamp accessories, greatly improving the processing efficiency, and fully meeting the urgent needs of complex lamp shapes for multi-point bending.

[0075] In addition, the bottom end of the inner wall of the second guide seat 8 is located on the same horizontal line as the bottom end of the inner wall of the first guide seat 6002, so as to ensure that the long strip accessory 9 can remain horizontal after entering the first guide seat 6002 along the inner cavity of the second guide seat 8, so as to further ensure that the long strip accessory 9 can remain horizontal when entering the second template 4007 and the first template 2004 for bending, so as to avoid the problem that the bending point of the long strip accessory 9 is deflected due to the inclination of the long strip accessory 9 and the influence of the qualified rate of the finished product of the bent lamp accessory; and the first template 2004 is set It is an alloy material, which can not only withstand the pressure exerted by the second template 4007 on the long strip accessory 9 to cause the long strip accessory 9 to form an arc curvature at the first template 2004, but also change the bending curvature of the first template 2004 when pressure is exerted on both ends while the first template 2004 is positioned in the middle, and the changed first template 2004 is still in a stable state. The components of the alloy material first template 2004 and the ratio of each component are all existing technologies. It can meet the above requirements and will not be described in detail here.

That is, the PLC controller 10 can control the operation timing of the above-mentioned parts, which is the existing technology; the above-mentioned existing components are not limited to the model or described in too much detail here.

[0077] The working principle of the lamp fitting processing and bending device in this embodiment is as follows:

[0078] The curvature of the first template 2004 is pre-adjusted to meet the processing requirements of the bending degree: the driving plate 3004 is driven to move backward by the turned-on first cylinder 3005, and the two sets of first driving rods 3002 are respectively moved along the inner cavity of the first slide groove 3001 at the corresponding position, so as to prompt the left and right sets of driving wheels 3003 to move backward synchronously. Since the middle part of the first template 2004 is fixedly connected to the horizontal support seat 2002, when the left and right ends of the first template 2004 are driven backward by the two sets of driving wheels 3003, the left and right ends of the first template 2004 are synchronously bent backward, prompting the first template 2004 to form an arc shape. By adjusting the displacement distance of the two sets of driving wheels 3003, the first template 2004 can be bent into arc-shaped molds of different degrees.

[0079] Then install the second template 4007 that is adapted to the curvature of the adjusted first template 2004: unscrew the first positioning pin 4006 from the side wall of the insert block 4005 to release it from the lock on the insert block 4005, move the insert block 4005 upward to cause it to disengage from the inner cavity of the slot 4004, and thus remove the second template 4007. Similarly, install the second template 4007 that is adapted to the curvature of the adjusted first template 2004 according to the above steps, slide the new insert block 4005 into the inner cavity of the slot 4004, and then rotate the first positioning pin 4006 to the side wall of the insert block 4005 to position the new insert block 4005 and the second template 4007.

[0080] After the adjustment, the position of the movable platform 5004 is adaptively adjusted: the first motor 5001 is turned on to drive the lead screw 5002 to rotate, so as to cause the movable base 5003 to move forward and backward along the left side of the workbench 1, so as to adjust the position of the lifting assembly 6 to correspond to the position between the first template 2004 and the second template 4007 after the adjustment;

[0081] The positions of the fan-shaped driving plates 7013 at the front and rear positions are adjusted to push the fan-shaped driving plates 7013 of the corresponding arc length to the positions close to the front and rear side walls of the long strip accessory 9: the second positioning pin 7018 is pulled out of the corresponding positioning hole 7022 cavity, and the rotating shaft 7016 is driven to rotate, so as to push the second positioning pin 7018 and the second driving rod 7019 to rotate. The rotation of the second driving rod 7019 pushes the two groups of moving pins 7011 in the cavities of the two groups of second limiting grooves 7020 on its outer wall to move in opposite directions, that is, the two fan-shaped driving plates 7013 correspondingly arranged above and below are displaced in opposite directions, so that one of the fan-shaped driving plates 7013 is close to the side wall of the long strip accessory 9 while the other is One fan-shaped driving plate 7013 is away from the side wall of the long strip accessory 9. Based on this principle, the relative positions of the front and rear fan-shaped driving plates 7013 are adjusted to ensure that the two fan-shaped driving plates 7013 with the same arc length are at the same distance from the side wall of the long strip accessory 9. The second positioning pin 7018 is screwed back into the corresponding positioning hole 7022 to achieve the locking of the positions of the rotation shaft 7016 and the second driving rod 7019 after the rotation adjustment. By adjusting the positions of the two groups of fan-shaped driving plates 7013 with different arc lengths, it is ensured that the two groups of fan-shaped driving plates 7013 can selectively contact the side wall of the long strip accessory 9 according to actual needs, thereby achieving intermittent pushing of the long strip accessory 9 at different travel distances.

[0082] After the PLC controller 10 presets the opening time of each part and the time for each instruction to act, the bending operation is performed: the long strip accessory 9 is placed in the second guide seat 8 and the inner cavity of the first guide seat 6002, and the long strip accessory 9 is ensured to be in a relatively stable state with the assistance of the guide wheel 6004; the second cylinder 4001 that is turned on first drives the mounting seat 4002, the second connecting seat 4003, and the second template 4007 to move toward the first template 2004, so as to apply pressure to the part of the long strip accessory 9 between the first template 2004 and the second template 4007, causing the part to form an arc-shaped bend, and the output end of the processed second cylinder 4001 is moved to the rear side. The first template 4007 is moved and reset, causing the second template 4007 to separate from the side wall of the bent long strip accessory 9; after the long strip accessory 9 is bent to a certain point, the first guide seat 6002 is driven to move upward under the action of the opened third cylinder 6001, causing the long strip accessory 9 in the first guide seat 6002 to move upward synchronously, and at this time, the arc-shaped long strip accessory 9 between the first template 2004 and the second template 4007 is also synchronously separated from the position upward; with the help of the opened second motor 7002, the first rotating rod 7004 is driven to rotate, so that the two first bevel gears 7005 respectively drive the second bevel gears 7006 at the corresponding positions to rotate in opposite directions at the same time, and at this time the front and rear The two second bevel gears 7006 rotate clockwise and counterclockwise respectively to ensure that the two sets of second rotating rods 7007 rotate clockwise and counterclockwise respectively. The front and rear sets of second rotating rods 7007 drive the fan-shaped driving plates 7013 at the corresponding positions to rotate simultaneously. When the fan-shaped driving plates 7013 close to the side walls of the long strip accessory 9 on the two second rotating rods 7007 rotate to fit the side walls of the long strip accessory 9, the fan-shaped driving plates 7013 that continue to rotate apply a rightward thrust to the side walls of the long strip accessory 9, causing the long strip accessory 9 to move one unit to the right along the inner cavity of the first guide seat 6002 until the fan-shaped driving plates 7013 are separated from the side walls of the long strip accessory 9. , thereby achieving intermittent pushing of the long strip accessory 9 to the right, at this time, the portion of the long strip accessory 9 that has been bent in the inner cavity of the first template 2004 and the second template 4007 moves to the right to leave this position, and prompts the portion of the long strip accessory 9 to be bent at the next point to correspond to the position between the first template 2004 and the second template 4007; the first guide seat 6002 is driven downward by the third cylinder 6001 to reset to the initial position, prompting the long strip accessory 9 to follow the first guide seat 6002 and descend to a position embedded between the first template 2004 and the second template 4007, so as to wait for the next time when the second template 4007 approaches the first template 2004 to perform bending processing;
