[0037] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0039] Embodiment, an automatic sheet metal component feeding and processing device, comprising a concave die 11 and a convex die 12,

[0040] The material carrier plate 2 is located between the concave die 11 and the convex die 12, and the material carrier plate 2 can perform transverse transmission on the plate material 02 clamped inside, and can also drive the plate material 02 to rise and fall;

[0041] A sorting cylinder 8 connected to the bottom of the die 11, wherein the inner wall of the sorting cylinder 8 is rotatably connected to a sorting assembly 9 capable of screening the finished blanks;

[0042] A feeding assembly 4 mounted at one end of a sorting cylinder 8;

[0043] The feeding assembly 4 comprises:

[0044] A plurality of loading plates 5 located on one side of the die 11, the loading plates 5 being used to clamp the sheet material 02;

[0045] The rotary drive structure 6 and the alignment push structure 7 are installed on the outer side wall of the sorting cylinder 8. The loading carrier plate 5 is installed on the rotary drive structure 6. When the rotary drive structure 6 rotates, the new sheet material 02 is delivered to one side of the feeding carrier plate 2. The alignment push structure 7 is placed on the side of the loading carrier plate 5 away from the die 11. The alignment push structure 7 can push the sheet material 02 in the loading carrier plate 5 into the feeding carrier plate 2.

[0046] The rotary drive structure 6 is also transmission-connected to the sorting assembly 9 .

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the feed carrier plate 2 comprises:

[0048] Two lifting frames 22 are hoisted on the external support structure through the lifting structure. A plurality of No. 1 bottom guide rollers 26 are fixedly installed on the side close to the two lifting frames 22. A plurality of No. 1 guide wheels 27 are fixedly installed on the side close to the two lifting frames 22. The No. 1 bottom guide rollers 26 are used to drive the two sides of the sheet material 02 to move upward when the lifting frames 22 are lifted. At the same time, the blank on the sheet material 02 is taken out from the die 11. During the transmission of the sheet material 02, the blank can pass between the No. 1 bottom guide rollers 26 on both sides. The No. 1 guide wheels 27 are used to limit and clamp the sheet material 02, and also play a guiding role during the transmission of the sheet material 02.

[0049] Two movable frames 21 are slidably connected to the lifting frame 22, such as Figure 8 In the embodiment, the two movable frames 21 are fixedly connected, and the movable frames 21 extend above the loading carrier plate 5;

[0050] like Figure 3 and Figure 4 In the embodiment, a plurality of feeding rollers 23 are fixedly installed between two movable frames 21, at least two of which can be pressed on the sheet material 02 clamped by the loading carrier plate 5, and the feeding rollers 23 are connected by transmission wheels and toothed belts. The feeding rollers 23 are used to transmit and press the sheet material 02, and the lifting frame 22 drives the movable frame 21 and the lifting frame 22 to lift, relying on the deadweight of the movable frame 21 and the feeding rollers 23 and pressing on the sheet material 02, and the transmission wheel on one of the feeding rollers 23 is driven to rotate by an external motor, and all the transmission wheels can be driven to rotate by the toothed belt, thereby driving the rotation of the feeding rollers 23 to transmit the sheet material 02;

[0051] The ratchet structures 3 arranged at both ends of the feeding roller 23 are used to limit the rotation direction of the feeding roller 23. The inside of the feeding roller 23 is rotatably connected with a shaft rod. The ratchet structure 3 is installed between the two ends of the feeding roller 23 and the shaft rod. When the alignment push structure 7 pushes the sheet material 02 on the loading carrier 5 into between the feeding roller 23 and the first bottom guide roller 26, the feeding roller 23 can convert the sliding friction between the feeding roller 23 and the sheet material 02 into rolling friction through passive rotation, thereby reducing the resistance of the sheet material 02 when entering the inside of the feeding carrier 2;

[0052] A plurality of connecting blocks 24 are movably connected on the outer wall of the lifting frame 22. Through the movably connected method, the distance between the two movable frames 21 can be adjusted, and the position of the No. 1 guide wheel 27 can be adjusted to adapt to the processing of sheets 02 of different sizes. The tops of the connecting blocks 24 are fixedly connected with sliding columns 25. The lifting frame 22 is slidably connected to the movable frame 21 through the connecting blocks 24 and the sliding columns 25. A pressure spring is installed between the top of the sliding column 25 and the movable frame 21. When the lifting frame 22 drives the movable frame 21 to descend, the sheet 02 moves downward between the feeding roller 23 and the No. 1 bottom guide roller 26. The sheet 02 first contacts the die 11. When the upper surface of the sheet 02 is in contact and the feed roller 23 is in contact with the sheet 02, the feed roller 23 elastically deforms and drives the movable frame 21 to slide on the slide column 25, and the pressure spring is squeezed and deformed. As the lifting frame 22 continues to move downward, the pressure spring continues to store force and deform. The pressure spring acts on the movable frame 21 through its own elasticity, and acts on the surface of the sheet 02 through the feed roller 23 to fix the position of the sheet 02 on the die 11. When the punch 12 moves downward to perform deep drawing on the sheet 02 on the die 11, the sheet 02 is prevented from deflecting. It can also absorb shock and energy when the sheet 02 contacts the die 11, and prevent the feed roller 23 from excessively pressing down on the sheet 02 to cause deformation.

[0053] like Figure 3 and Figure 5 In the embodiment, the ratchet structure 3 comprises:

[0054] A transmission ratchet 31 fixed on the shaft;

[0055] The collars 35 are fixedly connected to both ends of the transmission ratchet 31, and the collars 35 are rotatably connected to the shaft;

[0056] Rotate the pawl 32 connected to the inner wall of the collar 35;

[0057] A limit spring 33 fixedly mounted between the pawl 32 and the collar 35 is used to push the pawl 32 to return to its original position when the pawl 32 actively rotates with the collar 35;

[0058] The limiting column 34 fixedly connected to the inner wall of the collar 35 is used to limit and support the movement of the pawl 32 when the shaft drives the transmission ratchet 31 to rotate, so that the transmission ratchet 31 can drive the collar 35 and the feeding roller 23 to rotate on the shaft through the pawl 32 and the limiting column 34;

[0059] like Figure 2 , Figure 3 and Figure 4 In the embodiment, the loading carrier plate 5 comprises:

[0060] A carrier frame 51 fixedly connected to the rotary drive structure 6, wherein a plurality of second bottom guide rollers 52 are fixedly mounted on the inner side wall of the carrier frame 51;

[0061] The side clamping plates 53 are movably connected to the two sides of the carrier 51, and the side clamping plates 53 are slidably connected to the two sides of the carrier 51. The side clamping plates 53 are located on the side of the carrier 51 away from the feeding carrier 2 to prevent the shape of the side clamping plates 53 from affecting the activity space of the feeding roller 23 above the loading carrier 5. A plurality of clamping blocks 55 are fixedly connected to the side close to the two side clamping plates 53. The clamping blocks 55 are used to clamp the sheet material 0 when rotating with the rotating drive structure 6 to the top of the conveyor belt 01. 2. A No. 2 guide wheel 54 is fixedly installed at the bottom of each clamping block 55, and a clamping and releasing cylinder 56 is fixedly installed between the two side clamping plates 53. The No. 2 guide wheel 54 is used to rotate to one side of the feeding carrier plate 2 along with the rotating drive structure 6. After the clamping block 55 releases the clamping of the sheet material 02, it slides down between the No. 2 guide wheels 54 on the two side clamping plates 53, and limits and guides the moving sheet material 02 in the process of the sheet material 02 being pushed into the feeding carrier plate 2;

[0062] A plurality of compression springs are arranged between the carrier frame 51 and the side clamping plates 53. When the sheet material 02 is located between the two side clamping plates 53, there is no need to start the clamping and releasing cylinder 56. Through the elasticity of the compression springs, the side clamping plates 53 are pushed to drive the second guide wheel 54 to clamp the sheet material 02.

[0063] like Figure 2 and Figure 3 In the embodiment, the alignment and pushing structure 7 comprises a support cylinder 71 fixedly mounted on the sorting cylinder 8, a push plate 72 is slidably connected to the side of the support cylinder 71 close to the loading carrier 5, a push cylinder 73 is installed inside the support cylinder 71, and the output end of the push cylinder 73 is fixedly connected to the support cylinder 71. When the push cylinder 73 is started, the push plate 72 is driven by the output end thereof to push the sheet material 02 to move in the loading carrier 5 along the support cylinder 71, and the sheet material 02 in the loading carrier 5 is pushed into the feeding carrier 2;

[0064] like Figure 2 and Figure 6 In the embodiment, the rotary drive structure 6 comprises:

[0065] A driving motor 61 is fixedly connected to one end of the sorting cylinder 8, and a transmission rod is fixedly connected to the output shaft of the driving motor 61 through a coupling, and one end of the transmission rod penetrates and rotatably connects to the side wall of the sorting cylinder 8 and is fixedly connected to the sorting assembly 9;

[0066] A driving gear 62 fixedly sleeved on the transmission rod;

[0067] A transmission gear 63 fixedly mounted on one end of the sorting cylinder 8;

[0068] Rotate two swivels 65 connected to the outer wall of the sorting cylinder 8, and the two swivels 65 are fixedly connected through the loading carrier plate 5;

[0069] The passive gear ring 64 is fixedly mounted on the inner wall of the rotating ring 65, and the driving motor 61 is connected to the passive gear ring 64 through the transmission rod, the driving gear 62 and the transmission gear 63. When the driving motor 61 is started, the driving gear 62 is driven to rotate through the transmission rod, and the driving gear 62 drives the passive gear ring 64 to rotate through the transmission gear 63, thereby driving the rotating ring 65 to rotate on the outer wall of the sorting barrel 8. At the same time, the transmission rod will also drive the sorting component 9 to rotate inside the sorting barrel 8.

[0070] like Figure 2 , Figure 6 and Figure 7 In the embodiment, the sorting component 9 comprises:

[0071] A multi-faceted screen barrel 91 is rotatably connected to the inner wall of the sorting barrel 8, one end of which is transmission-connected to the rotary drive structure 6, one end of which is connected to the bottom of the die 11 through a blank collecting pipe 81, and the blank collecting pipe 81 is connected to one end of the multi-faceted screen barrel 91, and the multi-faceted screen barrel 91 is a spiral structure with a polygonal cross section;

[0072] A plurality of groups of guide bins 92 are provided in the same group. The guide bins 92 in the same group are equidistantly distributed on the edges of the multi-faceted screen barrel 91 along the spiral line. During the rotation of the multi-faceted screen barrel 91, the finished blanks and waste materials falling into the multi-faceted screen barrel 91 first enter the guide bin 92 on the lower edge, and slide to the other end of the guide bin 92 as the inclination angle of the guide bin 92 increases. The inclination angle of the guide bin 92 continues to increase, so that the finished blanks and waste materials fall from the guide bin 92 and slide along the inner wall of the multi-faceted screen barrel 91 to the lower edge. The waste materials pass through the sieve holes on the inner wall of the multi-faceted screen barrel 91 and fall onto the inner bottom wall of the sorting cylinder 8. The finished blanks can slide into the guide bin 92 on the lower edge of the multi-faceted screen barrel 91. As the multi-faceted screen barrel 91 rotates, the guide bin 92 at the lower position is continuously switched, thereby transmitting the finished blanks to the other end of the multi-faceted screen barrel 91.

[0073] A conduit 93 fixedly connected to one end of the multi-faceted screen barrel 91, the conduit 93 is connected to the material guide bin 92, one end of the conduit 93 is blocked by one side of the inner wall of the sorting barrel 8, when the conduit 93 is blocked by the sorting barrel 8, the finished blank is blocked inside the multi-faceted screen barrel 91;

[0074] A discharge pipe 94 fixedly connected to the inner wall of the sorting barrel 8, when the multi-faceted screen barrel 91 drives the guide tube 93 to rotate, the guide tube 93 is intermittently connected to the discharge pipe 94, so that the finished blank can be discharged from the sorting barrel 8;

[0075] The bottom of the sorting barrel 8 is tilted, and a waste discharge port 82 is provided at the bottom of the sorting barrel 8 .

[0076] In this embodiment, the sheet material 02 is lifted and lowered by the feeding carrier plate 2, and the blank on the sheet material 02 is transmitted to the mold for the next drawing operation. After the finished blank is trimmed by the punch 12, it enters the blank collecting pipe 81 through the blanking window on the die 11, and enters the sorting assembly 9 for finished blank sorting.

[0077] In this embodiment, Figure 1 The main structure of sheet 02 when feeding and connecting is shown in the figure.

[0078] A new sheet material 02 can be added during the deep drawing operation of the previous sheet material 02. When the lifting frame 22 carries the previous sheet material 02 downward and fixes it on the die 11, and is ready to be drawn through the punch 12: since the feed roller 23 extending above the carrier 51 is pressed down on the new sheet material 02 at the same time, one end of the new sheet material 02 is pressed against the second bottom guide roller 52 by the feed roller 23, and the new sheet material 02 is pushed by the push plate 72, the feed roller 23 passively rolls on the new sheet material 02, One end of the new sheet material 02 is first inserted above the adjacent No. 1 bottom guide roller 26, and then inserted below another adjacent feeding roller 23, so that after one end of the new sheet material 02 moves, it is first clamped by at least the feeding roller 23, the No. 1 bottom guide roller 26 and the No. 2 bottom guide roller 52, and the uninserted part is clamped by the No. 2 guide wheel 54, which has a guiding effect on the insertion of the new sheet material 02, so that the subsequent process of pushing the new sheet material 02 into the feeding carrier 2 to add the new sheet material 02 can be carried out stably;

[0079] When the blank is shifted to the next drawing position, the side clamping plate 53 is opened, and the lifting frame 22 carries the previous sheet 02 upward to separate the blank from the die 11, and can carry the new sheet 02 upward at the same time, and the driving device connected to the feeding roller 23 is started, and the shafts inside the multiple feeding rollers 23 are rotated through the transmission wheels and toothed belts at both ends of the feeding rollers 23, and the shafts drive the feeding rollers 23 to rotate through the transmission ratchet 31, the pawl 32 and the limit column 34, and the upper and lower sides of the sheet 02 are clamped by the feeding roller 23 and the No. 1 bottom guide roller 26, so as to synchronously clamp and transmit the new sheet 02 and the previous sheet 02, so that the two sheets 02 can participate in the multi-stage drawing operation at the same time;

[0080] When adding sheet material 02 subsequently, the side clamping plate 53 can be controlled to open on the carrier 51 through the clamping and releasing cylinder 56, and then the sheet material 02 transported by the conveyor belt 01 under the loading carrier 5 moves between the two side clamping plates 53, and then the side clamping plates 53 are controlled to close through the clamping and releasing cylinder 56, and the new sheet material 02 is clamped by the clamping block 55 on the inner side of the side clamping plate 53, and the driving motor 61 drives the active gear 62 to rotate, thereby driving the swivel 65 to rotate on the sorting barrel 8, and the loading carrier 5 on one side of the feeding carrier 2 is replaced to transfer the new sheet material 02. Repeating this operation can automatically connect the new sheet material 02 from the loading component 4 to the feeding carrier 2 without stopping, and perform loading and feeding operations.

[0081] When 1 is in use, waste and finished blanks generated by operations such as punching and trimming enter the multi-faceted screen barrel 91 through the blanking window on the die 11 and the blank collecting tube 81. When the rotating driving structure 6 drives the loading carrier 5 to transfer new sheet material 02, the multi-faceted screen barrel 91 is synchronously driven by the driving motor 61 to rotate inside the sorting cylinder 8. Since the multi-faceted screen barrel 91 is a spiral cavity structure with a polygonal cross-section, the guide bins 92 are distributed on the edges of the multi-faceted screen barrel 91 at intervals along the spiral line. When the multi-faceted screen barrel 91 rotates, the finished blanks and waste enter the guide bin 92. As the rotation angle of the guide bin 92 increases, the finished blanks and waste are simultaneously discharged from the guide bin 92. The finished blanks fall downward from the material guide bin 92 and enter the material guide bin 92 on the other edge below the multi-faceted screen barrel 91 along the inner wall of the material guide bin 92. In the process of the finished blanks and the waste material entering the material guide bin 92 at the other end from the material guide bin 92 at one end of the multi-faceted screen barrel 91, the waste material falls into the inner bottom end of the sorting barrel 8 through the sieve holes, and slides along the bottom end of the inclined inner wall of the sorting barrel 8 to the waste discharge port 82 to be gathered. The finished blanks pass through the material guide bins 92 on multiple edges and are gathered to the other end of the multi-faceted screen barrel 91. When the conduit 93 is connected to the discharge pipe 94, it is discharged through the other end of the sorting barrel 8 in the discharge pipe 94, thereby completing the automatic sorting of the finished blanks.
