Description

Technical Field

[0001] The invention relates to the field of optical fiber chassis shell bending, in particular to an optical fiber chassis shell processing and bending device. Background Art

[0002] ‌Chassis shell bending‌ is a key technology in sheet metal processing. Its accuracy and efficiency are crucial to the entire production process. Accurate design and planning are essential before starting any sheet metal processing. This includes selecting the right material, determining the thickness of the sheet, and making detailed bending drawings. It is usually done using laser cutting or water jet cutting technology to ensure high precision and edge quality. The determination of the bending sequence is the key to ensuring product quality. Usually, the bending sequence is arranged according to the complexity of the component and the fluidity of the material to avoid deformation and reduce springback. Different bending radii and sheet thickness require molds of different sizes and shapes. At the same time, the accuracy and repeatability of the bending machine will also affect the consistency of the product.‌ Since the bending process includes two processes, plastic and elastic deformation, springback is inevitable. The correct bending tolerance should be formulated during design. Springback can be reduced by adding ribs or improving the mold structure.‌ The shape of the sheet metal chassis should be as symmetrical as possible to prevent uneven force from affecting the bending accuracy. At the same time, positioning holes should be considered during design to ensure that they will not move during bending.

When there are holes on the board, the holes on the two boards need to be aligned after bending.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1

[0034] See also Figure 1-3 A chassis shell processing and bending device for optical fiber comprises an outer shell 1 and a transmission frame 2 and a bending head 3 installed at one end of the outer shell 1, the bending head 3 is located above the transmission frame 2, an adjustment device 4 is also installed at one end of the outer shell 1, the adjustment device 4 is located at one end of the bending head 3, the adjustment device 4 comprises a second electric push rod 45 installed at one end of the outer shell 1, two ends of the second electric push rod 45 are connected with a second clamping plate 44 and a first clamping plate 43, both sides of the second clamping plate 44 and the first clamping plate 43 are provided with a first electric push rod 42, one end of the first electric push rod 42 is connected with a second frame 41 and a first frame 40;

[0035] A clamping plate 51 is provided at one end of the second frame 41. The clamping plate 51 is used to abut against the chassis shell. A first circular hole 52 is provided inside the clamping plate 51. A plug post 53 is slidably connected inside the first circular hole 52. The plug post 53 is used to be inserted into the hole on the chassis shell.

[0036] One end of the second clamping plate 44 is slidably connected to a squeezing roller 48, and the squeezing roller 48 is used to squeeze the chassis shell to deform;

[0037] A second piston disc 55 is also slidably connected to the interior of the first circular hole 52. One end of the plug post 53 is connected to one end of the second piston disc 55. The second piston disc 55 is connected to the second frame 41 via a sixth spring 56. An air transfer port 57 is provided at one end of the second frame 41, and the air transfer port 57 is communicated with the first circular hole 52.

[0038] according to Figure 1 As shown, the sheet material is transferred to the lower end of the bending head 3 by the transfer rack 2, and then the bending head 3 is used to bend. When the bending head 3 is reset, according to Figure 2 As shown, the second clamping plate 44 and the first clamping plate 43 are driven to slide downward by the second electric push rod 45, and the second clamping plate 44 and the first clamping plate 43 drive the second frame 41 and the first frame 40 to slide downward, and the clamping plates 51 at one end of the second frame 41 and the first frame 40 are used to abut against the bent plate surface, so as to clamp the two plate surfaces and reduce the occurrence of separation of the two plate surfaces after bending;

[0039] according to Figure 3As shown, air is transmitted to the inside of the first circular hole 52 through the air transmission port 57, and the air squeezes the second piston disc 55 and the plug post 53 to slide toward one end. When the clamping plate 51 at one end of the second frame 41 abuts against the plate surface, the plug post 53 will abut against the plate surface. Then, when the second frame 41 and the first frame 40 continue to slide downward and squeeze, the plug post 53 moves to the two misaligned holes, and slides into the inside of the hole through the plug post 53. The plug post 53 is conical, and the diameter of the plug post 53 gradually increases, so the plug post 53 squeezes The two mutually misaligned holes are located at the same axis, so that the two panels are adjusted. At this time, after the hole position of one of the panels is adjusted, the position of the panel will be adjusted. Therefore, the squeezing roller 48 is then slid upward to squeeze the two panels, so as to shape the two panels, thereby completing the adjustment of the bending with errors and fixing the adjusted panels. In this way, when the holes on the two panels cannot be aligned after bending, the plug posts 53 and the squeezing roller 48 can be automatically adjusted to reduce the occurrence of product defects.

[0040] It should be particularly noted that when the pin 53 is inserted into the gap between the two offset holes, the pin 53 will first be inserted into the gap, and then the second frame 41 will continue to slide downward, so that the second frame 41 drives the pin 53 to slide downward, so that the pin 53 can expand the gap and be inserted into the two holes.

[0041] Example 2

[0042] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-5 A third electric push rod 46 is installed at the upper end of the second clamping plate 44 , and a piston rod 10 is slidably connected inside the third electric push rod 46 . A telescopic column 17 is installed at the lower end of the piston rod 10 , and one side of the squeezing roller 48 is connected to one side of the telescopic column 17 .

[0043] The telescopic column 17 includes an outer tube, a slide rod and a support spring. The inner part of the outer tube is slidably connected with the slide rod. The slide rod and the outer tube are connected by the support spring. One side of the squeezing roller 48 is connected to one side of the slide rod.

[0044] according to Figure 4 As shown, by transmitting liquid to the lower end of the piston rod 10, the liquid squeezes the piston rod 10 to slide upward, so that the piston rod 10 drives the telescopic column 17 to slide upward, and the telescopic column 17 drives the squeezing roller 48 to slide upward, and the squeezing roller 48 squeezes the two plate surfaces to shape;

[0045] A limiting rod 49 is provided between the second frame 41 and the first frame 40. The limiting rod 49 is used to limit the sliding distance of the squeezing roller 48. The limiting rod 49 and the second frame 41 are connected via a third spring 18.

[0046] A rubber ball is installed at one end of the limiting rod 49, and a plurality of slots are provided on the inner wall of the second frame 41;

[0047] A limiting device 7 is installed at the lower end of the limiting rod 49, and the limiting device 7 includes an adjustment frame 71 connected to the lower end of the limiting rod 49, and the lower end of the adjustment frame 71 is slidably connected to an adjustment column 78, and the inside of the adjustment frame 71 is slidably connected to a shaft column 76, and one end of the shaft column 76 is installed with a trapezoidal plate 77, which is used to squeeze the adjustment column 78 to slide downward.

[0048] according to Figure 4 As shown, when the second frame 41 slides downward, its limit rod 49 will abut against the upper ends of the two plate surfaces, so that the plate surfaces are used to squeeze the limit rod 49 to slide upward, and then when the piston rod 10 pulls the telescopic column 17 and the squeezing roller 48 to slide upward to squeeze the plate surface, a button is installed at one end of the telescopic column 17, and the button is electrically connected to the air pump. Therefore, when the button at one end of the telescopic column 17 that slides upward abuts against the limit rod 49, the button sends a signal, so that the air pump stops transmitting air to the inside of the third electric push rod 46, so that the squeezing roller 48 stops sliding upward, thereby reducing the adjustment time and improving the processing effect;

[0049] Further, according to Figure 3 and Figure 5 As shown, in order to improve the squeezing effect of the squeezing roller 48, the squeezing roller 48 needs to squeeze to the top of the board surface and slide upward for a distance to completely squeeze the board surface. For this purpose, an adjustment frame 71 and an adjustment column 78 are installed at the lower end of the limit rod 49. Figure 5 As shown, the adjusting column 78 abuts against the trapezoidal plate 77, so that when the second frame 41 slides downward, the adjusting column 78 abuts against the upper ends of the two plate surfaces, thereby increasing the upward sliding distance of the squeezing roller 48, thereby improving the squeezing effect of the plate surface;

[0050] It should be particularly noted that when the upper end of the plate surface squeezes the limit rod 49 to slide upward, the rubber ball at one end of the limit rod 49 is buckled in the slot to fix the limit rod 49 and determine the upward sliding distance of the squeezing roller 48.

[0051] Example 3

[0052] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-7 The third electric push rod 46 is provided with a first piston cavity 8 inside, the upper end of the piston rod 10 is slidably connected to the inside of the first piston cavity 8, and the upper end of the piston rod 10 is connected to the inside of the third electric push rod 46 via a first spring 9;

[0053] A second hose 12 is disposed on one side of the third electric push rod 46, and the second hose 12 is connected to the third electric push rod 46. A first hose 11 is also disposed at the lower end of the third electric push rod 46, and the lower end of the first hose 11 is connected to the upper end of the limit rod 49;

[0054] A second piston chamber 13 is provided on one side of the limiting rod 49, and a first piston disc 15 is slidably connected inside the second piston chamber 13. The first piston disc 15 and the limiting rod 49 are connected via a second spring 14. A clamping column 16 is installed on one side of the first piston disc 15. The clamping column 16 passes through one side of the limiting rod 49, and the first piston disc 15 and the limiting rod 49 are connected via the second piston chamber 13.

[0055] according to Figure 6 and Figure 7 As shown, a piston rubber plate is installed at the upper end of the piston rod 10, and the piston rubber plate is slidably connected to the inside of the third electric push rod 46. Air is transmitted to the lower end of the piston rubber plate through the second hose 12, and the air is used to squeeze the piston rubber plate to slide upward. The piston rubber plate drives the piston rod 10, the telescopic column 17 and the squeezing roller 48 to slide upward, so that the squeezing roller 48 is used to squeeze the two plate surfaces to shape, and then when the telescopic column 17 contacts the clamping column 16, according to Figure 7 As shown, the first piston disc 15 is pushed to slide to the left by the clamping column 16, so that the first piston disc 15 is no longer sealed at the lower end of the first hose 11. Figure 6 As shown, since the lower end of the first hose 11 is no longer sealed, the air transmitted by the second hose 12 to the third electric push rod 46 will flow to the first hose 11, and the air will be transmitted to the second piston chamber 13 through the first hose 11. Figure 7 As shown, the lower end of the limit rod 49 is provided with a through slot hole, which is connected to the second piston chamber 13. Therefore, the first hose 11 will discharge the air through the through slot hole, so that the piston rod 10 stops sliding upward, and the height of the board surface is automatically determined by the limit rod 49 and the limit device 7, so that the squeezing roller 48 can extrude a board surface of any height.

[0056] Example 4

[0057] This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-9 , one end of the first frame 40 is slidably connected to the extrusion plate 19, and the extrusion plate 19 is connected to the fourth spring 20 through the fourth spring 20;

[0058] Two air bags 21 are also installed at one end of the second frame 41. A shift plate 23 is arranged between the two air bags 21. The shift plate 23 and the second frame 41 are connected via a fifth spring 22. A first nozzle 72 and a second nozzle 73 are respectively arranged inside the two air bags 21.

[0059] A third piston chamber 74 is also provided inside the adjustment frame 71, and a third piston disc 75 is slidably connected inside the third piston chamber 74. The third piston disc 75 is connected to the adjustment frame 71 via a return spring 79. One end of the third piston disc 75 is connected to one end of the shaft column 76. One end of the first nozzle 72 and one end of the second nozzle 73 are respectively connected to the interior of the third piston chamber 74.

[0060] When the two holes are misaligned, when the two plates are moved by inserting the plug 53 into the hole, two situations may occur. First, one of the plates is squeezed and slid downward by the plug 53, resulting in a small arc pulled downward on the upper end of the plate. Second, when one of the plates is squeezed and slid upward by the plug 53, a small arc arched upward on the upper end of the plate appears. Both of the above situations will cause the height of the plate to change. When the squeezing roller 48 squeezes the small arc and folds it in half, the height of the plate will change again, resulting in the upward squeezing range of the squeezing roller 48 being inaccurate. Therefore, it is necessary to determine the change of the plate in advance.

[0061] according to Fig. 9 As shown, when the plug 53 squeezes the hole to move its position, its plate surface will adjust its position, so when the toggle plate 23 contacts the plate surface, the adjusted plate surface will frictionally drive the toggle plate 23 to slide upward or downward, thereby squeezing the airbag 21 to contract through the toggle plate 23, so that the air inside the airbag 21 is transmitted to the third piston chamber 74 through the second nozzle 73 or the first nozzle 72, and the second nozzle 73 and the first nozzle 72 are respectively located on both sides of the third piston plate 75;

[0062] When the second nozzle 73 transmits air to squeeze the third piston disc 75 to slide toward one end, the third piston disc 75 drives the shaft column 76 and the trapezoidal plate 77 to slide toward one end. Since the trapezoidal plate 77 is trapezoidal, the upward sliding distance of the adjustment column 78 is increased, thereby increasing the upward sliding range of the squeezing roller 48;

[0063] When the first nozzle 72 transmits air to squeeze the third piston disc 75 to slide toward the other end, the third piston disc 75 drives the shaft column 76 and the trapezoidal plate 77 to slide toward the other end. Since the trapezoidal plate 77 is trapezoidal, the upward sliding distance of the adjustment column 78 is reduced, thereby reducing the upward sliding range of the squeezing roller 48;

[0064] In this way, the upward sliding range of the squeezing roller 48 can be automatically adjusted according to the plate surface adjustment method through the above method, so as to achieve better bending.

[0065] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
