The aluminum plate 2 is placed on the static die, the driving device drives the moving die to press down, and the moving die and the static die combine to press the aluminum plate 2 into a shell 3. A positioning plate is further arranged on the static die to position the aluminum plate, so that the aluminum plate and the static die are arranged concentrically.

[0015] Furthermore, the material handling device includes a material handling plate, which is slidably disposed on the upper surface of the positioning plate in the front-back direction.

Several grooves corresponding to the positioning blocks are opened on the inner side wall of the material handling plate. Each positioning block is located in the corresponding groove and is slidably connected to the material handling plate. A positioning spring is fixedly disposed on the outer side of each positioning block. The outer end of the positioning spring is fixedly disposed on the inner side wall of the groove. A limit block is fixedly disposed on the outer side of the positioning block. A limit groove adapted to the limit block is opened on the inner side wall of the groove of the positioning plate. The positioning block is slidably connected to the material handling plate through the limit block and the limit groove. The positioning spring always drives the positioning block to move inward until the limit block is limited by the limit groove. The positioning block is L-shaped. When the positioning block moves to the innermost position, the inner side of the vertical part of the positioning block contacts the aluminum plate to achieve positioning of the aluminum plate. The inner side of the horizontal part of the positioning block coincides with the inner side wall of the through hole of the positioning plate.

[0016] A stamping method based on an automatic aluminum product stamping device includes: A) placing an aluminum plate on the material table at the feeding position; B) pressing the start button, the second hydraulic telescopic rod drives the pressure block to move downwards for a pneumatic press, and simultaneously the pressure block presses downwards, causing the feeding rod to move to the left, which in turn causes the picking rod to move to the left above the feeding position. A vacuum generator generates a vacuum, and the suction nozzle picks up the aluminum plate; C) the second hydraulic telescopic rod drives the pressure block to lift upwards; D) the lifting of the pressure block drives the feeding rod to move to the right, which in turn causes the picking rod to move to the right. The aluminum plate is placed in the positioning plate device, the vacuum generator stops, and the suction nozzle disengages from the aluminum plate; E) the operator places the aluminum plate at the feeding position; F) the pressure block presses down and cooperates with the column to press the aluminum plate into a shell; G) the pressure block lifts up, and the operator pulls the picking plate forward using the handle to move it to the upper end of the material box, whereupon the shell automatically falls into the material box; the next steps are: DEF G- DEF G- DEFG.

[0017] I. This invention, by setting up a driving device, a pressure block, a column, a positioning plate, an automatic feeding device, and a material handling device, allows for the following steps during use: A) Place an aluminum plate at the feeding position; B) Press the start button, and the driving device drives the pressure block downwards for one air compression; C) The driving device drives the pressure block upwards; D) As the pressure block rises, the automatic feeding device places the aluminum plate from the feeding position into the positioning plate device; E) The operator places the aluminum plate at the feeding position; F) The pressure block presses down, cooperating with the column to press the aluminum plate into a shell; G) The pressure block rises, and the operator removes the shell using the material handling device. The subsequent steps are: DEF G- DEF G- DE FG. This achieves continuous production after a single start, and the operator's hand needs to be inserted under the pressure block, improving safety.

[0018] II. This invention, by setting up a material-picking rod, a fixed plate, a damping plate, a vertical plate, and a damping block, allows the material-picking rod to release material. When the material-picking rod releases material, the sudden release of the spring force causes the fixed plate and the material-picking rod to move downwards. At the same time, the fixed plate simultaneously causes the vertical plate to move downwards, and the vertical plate causes the damping block to move downwards. However, the damping block can only slide downwards along the slope of the damping plate, resulting in two movements: vertical downward movement and horizontal outward movement. The force of the horizontal movement acts as a force to prevent the vertical plate from moving downwards, thus damping the downward movement of the vertical plate. This, in turn, dampens the downward movement of the fixed plate, making the downward movement of the fixed plate and the material-picking rod more stable and smooth, without generating impact vibrations. Consequently, the suction nozzle can place the aluminum plate more stably in the positioning device. Attached Figure Description

[0021] Please see Figures 1-23 The present invention will now be described in detail with reference to the accompanying drawings and embodiments: The automatic stamping device for aluminum products of the present invention includes a base 1, a driving device fixedly mounted on the top of the base 1, a moving mold fixedly mounted on the output end of the driving device, and a stationary mold fixedly mounted on the upper surface of the base 1. An aluminum plate 2 is placed on the stationary mold, and the driving device drives the moving mold to press down. The moving mold and the stationary mold combine to press the aluminum plate 2 into a shell 3. The stationary mold includes a column 4 fixed to the upper surface of the base 1, and the moving mold includes a pressing block 5 fixedly mounted to the output end of the driving device. The lower surface of the pressing block 5 has a mold groove 6 that matches the upper surface of the column 4. The cross-sectional shape of the mold groove 6 is similar to the cross-sectional shape of the column 4, with a similarity ratio greater than 1; that is, the pressing block 5... The downward pressure causes the top of the column 4 to insert into the mold groove 6 of the pressure block 5, and there is a set gap between the side wall of the column 4 and the side wall of the mold groove 6. In use, the aluminum plate 2 is placed on the upper end face of the column 4. The shape of the aluminum plate 2 and the shape of the upper end face of the column 4 are similar figures. The area of ​​the lower end face of the aluminum plate 2 is larger than the area of ​​the upper end face of the column 4. Therefore, each edge of the aluminum plate 2 extends outward from the column 4 by an equal set distance. The downward pressure of the pressure block 5 bends the part of the aluminum plate 2 that extends to the outside and fits it against the outer side of the column 4 to form the shell 3. The similar figure here is a geometric concept in mathematics, defined as two figures with corresponding angles equal and corresponding sides proportional.

[0022] Therefore, the aluminum plate 2 needs to be positioned so that it is concentric with the column 4. In this embodiment, a positioning device is provided around the column 4. The positioning device includes a positioning plate 7. Several guide posts 8 are fixedly provided on the upper end face of the base 1. The positioning plate 7 is fitted with each guide post 8. The upper end face of the positioning plate 7 is provided with a through hole 9 that matches the upper end face of the column 4. The shape of the through hole 9 and the shape of the upper end face of the column 4 are two similar figures and the two similar figures are congruent. Several positioning blocks 10 are provided around the through hole 9 on the upper end face of the positioning plate 7. Several support springs 11 are fixedly provided between the positioning plate 7 and the base 1. A nut 12 is fixedly provided at the top of each guide post 8. The support spring 11 pushes upward to position the guide post. The plate 7 moves, causing the upper surface of the positioning plate 7 to abut against the nut 12. In use, the aluminum plate 2 is placed on the positioning plate 7 and positioned between several positioning blocks 10. At this time, the aluminum plate 2 is concentrically positioned with the column 4. Then, the driving device drives the pressure block 5 to press down. The pressure block 5 first contacts each positioning block 10, forcing the positioning plate 7 to move downwards and compress the support spring 11. The aluminum plate 2 moves downwards synchronously with the positioning plate 7. When the lower surface of the aluminum plate 2 contacts the upper surface of the column 4, the positioning plate 7 continues to move downwards, but the aluminum plate 2 remains on the upper surface of the column 4. The mold groove 6 of the pressure block 5 is fitted onto the top of the column 4, causing each edge of the aluminum plate 2 to bend downwards and fit against the outer surface of the column 4 to form the shell 3. Figure 17 and 18As shown; then the pressure block 5 is lifted to complete the stamping. At this time, the positioning plate 7 moves upward under the drive of the support spring 11. The through hole 9 of the positioning plate 7 is completely fitted with the outer side of the column 4. Therefore, when the positioning plate 7 moves upward, it will peel the aluminum plate 2 forming the shell 3 off the column 4, as shown. Figure 19 As shown, this facilitates removal and completes one pressing operation.

[0023] The existing process requires manual feeding and unloading of materials. The workflow is as follows: aluminum plate 2 is manually placed on positioning plate 7, the machine is started, pressure block 5 presses down, pressure block 5 is raised, the machine is stopped, the finished aluminum shell 3 is manually removed, aluminum plate 2 is manually placed on positioning plate 7, and the machine is started again. Since the operator's hands need to reach under pressure block 5 multiple times, the machine needs to be started and stopped manually for safety reasons. There are buttons for starting and stopping, which need to be pressed manually. The process flow is not smooth, the operation steps are cumbersome, and the production efficiency is affected.

[0024] In this embodiment, a workbench 13 is fixedly installed on the left side of the base 1, an automatic feeding device is installed on the upper surface of the workbench 13, and a material picking device is installed on the upper surface of the positioning plate 7. The material picking device and the positioning device are fixedly installed, and a material placement position 14 is installed on the upper surface of the workbench 13. The operation process is as follows: the operator stands in front of the workbench 13, A, places the aluminum plate 2 in the material placement position 14, B, presses the start button, the drive device drives the pressure block 5 to move downward to perform one air compression, C, the drive device drives the pressure block 5 to lift up, D, the pressure block 5 lifts up and the automatic feeding device places the aluminum plate 2 in the material placement position 14 into the positioning plate 7 device, E, the operator places the aluminum plate 2 in the material placement position 14, F, the pressure block 5 presses down and cooperates with the column 4 to press the aluminum plate 2 into a shell 3, G, the pressure block 5 lifts up and the operator removes the shell 3 through the material picking device; the next steps are DEF G- DEF G- DEFG.

[0025] The above operation method does not require stopping the machine. The operator only needs to put the material in the feeding position 14 and then pick it up through the material picking device. Moreover, the operator's hands do not need to reach under the pressure block 5, which improves safety, improves the flow of the process, and improves production efficiency.

[0026] In this embodiment, the automatic feeding device includes a fixed plate 15 fixedly installed on the upper surface of the workbench 13. A feeding rod 16 is slidably installed in the fixed plate 15 in the left and right direction. A feeding device is installed at the right end of the feeding rod 16. When the pressure block 5 is lifted, it drives the feeding rod 16 to move to the right. The feeding device enters above the positioning device and places the aluminum plate 2 in the positioning device. When the pressure block 5 moves downward, it drives the feeding rod 16 to move to the left. The feeding rod 16 drives the feeding device to move to the left to the feeding position 14. The feeding device takes out the aluminum plate 2 in the feeding position 14. The pressure block 5 presses down to press the aluminum plate 2 into a shell 3.

[0027] In this embodiment, the feeding device includes a feeding rod 17 that slides vertically on the feeding rod 16. A suction nozzle 18 is provided at the bottom end of the feeding rod 17, and a fixed plate 19 is fixedly provided at the top end of the feeding rod 17. A feeding spring 20 is fixedly provided between the fixed plate 19 and the feeding rod 16. A trigger block 21 is fixedly provided on the upper surface of the fixed plate 19. A trigger rod 22 slides horizontally within the fixed plate 15. A following spring 23 is fixedly provided at the left end of the trigger rod 22 via a limiting device. The left end of the following spring 23 is fixedly provided to the fixed plate 15. A fitting for the trigger rod 22 is provided on the left side of the trigger block 21. The slot 24; a limiting block 25 is fixedly installed inside the fixing plate 15, and a first inclined surface 26 is opened on the upper end surface of the limiting block 25; a limiting rod 27 is fixedly installed on the outer surface of the fixing plate 19, and a second inclined surface 28 that matches the first inclined surface 26 is opened on the left end of the limiting rod 27; when the feeding rod 16 moves to the right, the right end of the trigger rod 22 is inserted into the slot 24 of the trigger block 21 and moves to the right with the feeding rod 16 (the force of the trigger rod 22 moving to the right with the feeding rod 16 comes from the following spring 23); when the feeding rod 16 moves to the right so that the picking rod 17 is above the positioning device, the limiting device restricts the trigger rod 22 from moving to the right. The rightward movement causes the right end of the trigger rod 22 to disengage from the slot 24 of the trigger block 21. At this time, the feeding spring 20 pulls the fixed plate 19 downward, and the fixed plate 19 drives the picking rod 17 downward. The picking rod 17 drives the suction nozzle 18 downward, so that the aluminum plate 2 adsorbed by the suction nozzle 18 is placed in the positioning device. Then, the feeding rod 16 moves to the left. At this time, the second inclined surface 28 of the limiting rod 27 is in contact with the first inclined surface 26 of the limiting block 25. The limiting rod 27 is forced to move upward as it moves to the left. As the feeding rod 16 moves to the left, the limiting rod 27 drives the fixed plate 19 upward, and the fixed plate 19 drives the trigger block 21 upward. When the right end of the trigger rod 22 aligns with the slot 24 of the trigger block 21, the trigger rod 22 inserts into the slot 24 to the right. This achieves the purpose of lifting the material rod 17 when the feeding rod 16 moves to the left after the aluminum plate 2 is placed on the material picking rod 17, and finally locking it with the trigger rod 22. Until the feeding rod 16 moves to the left, driving the material picking rod 17 to the discharge position 14, the suction nozzle 18 at the bottom of the material picking rod 17 adsorbs the aluminum plate 2, completing the material picking (at the same time, the limiting rod 27 moves to the left and enters the sliding hole opened in the fixing plate 15. The sliding hole is set to limit the rod 27 to move to the left normally). Then the feeding rod 16 waits for the next feeding. When the suction nozzle 18 picks up the material, it generates a negative pressure to adsorb the aluminum plate 2. When the suction nozzle 18 discharges the material, the negative pressure disappears, and the aluminum plate 2 is detached.

[0028] In this embodiment, the limiting device includes a slider 29 fixedly disposed at the left end of the trigger rod 22. The slider 29 is slidably disposed in the chute 30 opened on the upper surface of the fixed plate 15 in the left-right direction. The right end of the follower spring 23 is fixedly disposed with the slider 29, and the left end of the follower spring 23 is fixedly disposed with the left side wall of the chute 30. When the slider 29 slides to the right to the right end of the chute 30, the slider 29 is restricted from moving by the chute 30, thereby restricting the trigger rod 22 from continuing to move to the right. During normal use, several shims are sleeved on the trigger rod 22 located in the chute 30. By adding or removing shims, the extreme position of the slider 29 moving to the right can be finely adjusted, thereby adjusting the timing of the trigger rod 22 disengaging from the trigger block 21.

[0029] When the feeding spring 20 drives the picking rod 17 to move downward through the fixed plate 19 and feeds the material through the suction nozzle 18, the force of the feeding spring 20 is suddenly released, causing the picking rod 17 to drive the suction nozzle 18 to descend rapidly and place the aluminum plate 2 in the positioning device. During this process, the picking rod 17 is prone to vibration, which causes the aluminum plate 2 to be placed unevenly, which can easily lead to the failure of placing the aluminum plate 2 and thus press out defective products.

[0030] To solve the above problems, in this embodiment, two parallel plates 31 are fixedly installed at the right end of the feeding rod 16, and the picking rod 17 is slidably connected to the two parallel plates 31 in the vertical direction; two damping plates 32 are installed between the two parallel plates 31, and the two damping plates 32 are located on both sides of the picking rod 17, and the outer surface of each damping plate 32 is inclined; two vertical plates 33 are slidably installed radially on the lower end face of the fixed plate 19, and a damping block 34 is installed at the bottom end of each vertical plate 33, and the lower end face of each damping block 34 is slidably connected to the corresponding damping plate 32; the bottom end of the releasing spring 20 is fixedly installed with the upper parallel plate 31, so as to achieve the purpose of fixing the releasing spring 20 to the feeding rod 16 through the upper parallel plate 31; in use, when the trigger rod 22 is released from the trigger block 2 When the material is disengaged from slot 24, the sudden release of the spring force of the feeding spring 20 will cause the fixed plate 19 and the picking rod 17 to move downward. At the same time, the fixed plate 19 will also cause the vertical plate 33 to move downward. The vertical plate 33 will cause the damping block 34 to move downward. However, the damping block 34 can only slide downward along the slope of the damping plate 32, so that the damping block 34 has two movements: vertical downward and horizontal outward. The force of the horizontal movement is to prevent the vertical plate 33 from moving downward, thus damping the downward movement of the vertical plate 33. In turn, it dampens the downward movement of the fixed plate 19, making the downward movement of the fixed plate 19 and the picking rod 17 more stable and smooth, without impact vibration. This allows the suction nozzle 18 to place the aluminum plate 2 in the positioning device more stably.

[0031] In actual use, operators may encounter various problems, one of which is the failure of the material picker 17 to release material. If, through repeated observation of the material picker 17's release process, it is found that the failure is caused by the material picker 17 descending too quickly, then this problem can be solved by adjusting the damping force between the damping block 34 and the damping plate 32. The specific technical solution and working principle are as follows: In this embodiment, the bottom end of the damping plate 32 is hinged to the lower parallel plate 31, and the upper end surface of the damping plate 32 is in sliding contact with the upper parallel plate 31. An adjustment device is installed on the lower parallel plate 31. The adjustment device is used to adjust the tilt angle of the outer side of the damping plate 32. The tilt angle is the angle α between the outer side of the damping plate 32 and the horizontal plane. The smaller α is, the greater the damping force of the damping block 34 moving downward. The larger α is, the smaller the damping force of the damping block 34 moving downward. By adjusting the size of α by the adjustment device, the downward movement speed of the fixed plate 19 and the picking rod 17 is controlled, thereby achieving the purpose of smooth material feeding by the picking rod 17.

[0032] In this embodiment, the adjusting device includes an adjusting nut 35 rotatably connected to the lower parallel plate 31. An adjusting screw 36 is internally threaded onto the adjusting nut 35 and slidably connected to the lower parallel plate 31 in the vertical direction. An adjusting block 37 is hinged to the top of the adjusting screw 36 and slidably disposed with the inner side of the damping plate 32 in the vertical direction. The inner side of the damping plate 32 corresponding to the adjusting block 37 is an inclined surface. (See reference...) Figure 14 and 15 In use, rotating the adjusting nut 35 causes the adjusting screw 36 to move up and down, which in turn causes the adjusting block 37 to move up and down, which in turn causes the damping plate 32 to rotate. This achieves the purpose of adjusting the tilt angle 'a' of the outer side of the damping plate 32, and thus the purpose of adjusting the descent speed of the fixed plate 19 and the picking rod 17. By repeatedly observing and adjusting 'a', and then observing again, a stable material feeding is finally achieved without making the descent speed of the picking rod 17 too slow.

[0033] In this embodiment, a bushing 38 is fixedly provided on the upper end face of the adjusting nut 35. The bushing 38 is located inside the lower parallel plate 31 and is rotatably connected to the lower parallel plate 31. The bushing 38 is sleeved with the adjusting screw 36. A guide groove 39 is provided on the outer surface of the adjusting screw 36 along the vertical direction. A guide bar 40 is fixedly provided in the lower parallel plate 31 along the vertical direction. The guide bar 40 is located in the guide groove 39. This achieves the purpose that the adjusting screw 36 can only move up and down and cannot rotate within the lower parallel plate 31.

[0034] In this embodiment, a crossbeam 41 is fixedly installed at the bottom end of the material picking rod 17, and two suction nozzles 18 are fixedly installed on the lower end face of the crossbeam 41. The suction nozzles 18 are made of rubber.

[0035] In this embodiment, air channels are provided in the suction nozzle 18, crossbeam 41, material picking rod 17, and feeding rod 16. A connector 42 is fixedly installed on the rear side of the fixing plate 15. One end of the connector 42 is connected to the air channel of the feeding rod 16, and the other end of the connector 42 is connected to the vacuum generator 43. The vacuum generator 43 includes three interfaces: a first interface 44, a second interface 45, and a third interface 46. During operation, compressed air enters from the first interface 44 and exits from the second interface 45, forming a negative pressure at the third interface 46. The negative pressure is transmitted through the connector 42 to the air channels in the feeding rod 16, material picking rod 17, crossbeam 41, and suction nozzle 18, thereby creating a negative pressure at the bottom of the air channel on the lower end face of the suction nozzle 18 to adsorb the aluminum plate 2. When the compressed air stops, the negative pressure disappears, and the suction nozzle 18 releases the material. The opening and closing of the compressed air is automatically controlled by a solenoid valve.

[0036] In this embodiment, a connecting pipe 47 is fixedly installed on the lower end face of the feeding rod 16. The upper end face of the connecting pipe 47 is fixedly installed with the parallel plate 31 below. A circular hole 48 communicating with the internal air channel is opened on the outer surface of the picking rod 17. The circular hole 48 is located inside the connecting pipe 47. When the picking rod 17 moves up and down, the circular hole 48 moves up and down inside the connecting pipe 47, but always remains inside the connecting pipe 47. The left side of the upper end face of the connecting pipe 47 is fixedly installed with the feeding rod 16, and the left end of the connecting pipe 47 communicates with the air channel inside the feeding rod 16.

[0037] In this embodiment, the rear side of the feeding rod 16 is provided with an elongated hole 49 communicating with the internal air channel in the left-right direction. The inner end of the connector 42 is located in the elongated hole 49. When the feeding rod 16 moves left and right, the inner end of the connector 42 is always located in the elongated hole 49 and always communicates with the air channel of the feeding rod 16. The air flow path is: connector 42, elongated hole 49, air channel inside the feeding rod 16, inside the connecting pipe 47, round hole 48 of the picking rod 17, air channel inside the picking rod 17, air channel inside the crossbeam 41, air channel inside the suction nozzle 18, and finally communicates with the outside from the bottom of the suction nozzle 18.

[0038] In order to achieve the purpose of moving the pressing block 5 upward to drive the feeding rod 16 to the right, and moving the pressing block 5 downward to drive the feeding rod 16 to the left, in this embodiment, a vertical rod 50 is slidably connected inside the fixed plate 15 along the vertical direction. The top end of the vertical rod 50 is fixedly set to the pressing block 5. A transmission device is provided between the vertical rod 50 and the feeding rod 16. When the vertical rod 50 moves upward, it drives the feeding rod 16 to the right through the transmission device. When the vertical rod 50 moves downward, it drives the feeding rod 16 to the left through the transmission device.

[0039] Please see Figure 8 and Figure 9In this embodiment, the transmission device includes a first gear 51 and a first bevel gear 52 coaxially fixed to each other, and a second gear 53 and a second bevel gear 54 coaxially fixed to each other. The first gear 51 and the first bevel gear 52 are rotatably connected to the fixed plate 15, and the second gear 53 and the second bevel gear 54 are also rotatably connected to the fixed plate 15. A first rack 55 is fixedly mounted on the right side of the vertical rod 50, and a second rack 56 is fixedly mounted on the front side of the feeding rod 16. The first rack 55 meshes with the first gear 51, the first bevel gear 52 meshes with the second bevel gear 54, and the second gear 53 meshes with the second rack 56. Please refer to [link to previous section]. Figure 8 and Figure 9 The vertical rod 50 moves downward, driving the first gear 51 to rotate via the first rack 55. The first gear 51 drives the first bevel gear 52 to rotate, the first bevel gear 52 drives the second bevel gear 54 to rotate, and the second bevel gear 54 drives the second gear 53 to rotate. The second gear 53 drives the feeding rod 16 to move to the left via the second rack 56. Conversely, the vertical rod 50 moves upward, driving the feeding rod 16 to move to the right. This achieves the purpose of the pressure block 5 moving upward, driving the feeding rod 16 to move to the right, so that the picking rod 17 can place the aluminum plate 2 downward, and the purpose of the pressure block 5 moving downward, driving the feeding rod 16 to move to the left, so that the feeding rod 16 drives the picking rod 17 to the material release position 14 to adsorb the aluminum plate 2.

[0040] Another reason for the failure of material feeding by the picking rod 17 is that the picking rod 17 moves too little or too much to the right. If this problem is found, it can be solved by adjusting the relative position of the vertical rod 50 and the pressure block 5. The specific technical solution and working principle are as follows: In this embodiment, a horizontal plate 57 is fixedly installed on the upper end face of the pressure block 5. The left end of the horizontal plate 57 is slidably connected to the vertical rod 50 in the vertical direction. An L-plate 58 is fixedly installed on the upper end face of the horizontal plate 57. An adjusting bolt 59 is rotatably connected to the L-plate 58. A threaded hole is opened on the upper end face of the vertical rod 50. The adjusting bolt 59 is threadedly connected to the vertical rod 50 through the threaded hole. Rotating the adjusting bolt 59 can drive the vertical rod 50 to move up or down, thereby achieving the purpose of adjusting the relative position of the vertical rod 50 and the pressure block 5. Specific usage method: First, the pressure block 5 moves upward and stops. At this time, observe the relative position of the feeding rod 17 and the positioning device. The suction nozzle 18 is adsorbed with aluminum plate 2. Observe the relative position of aluminum plate 2 and the positioning device. Observe whether the position of aluminum plate 2 is biased to the right or left. If it is biased to the right, rotate the adjusting bolt 59 to make the vertical rod 50 move downward. The downward movement of the vertical rod 50 drives the feeding rod 16 to move to the left. Then observe whether the position of aluminum plate 2 is centered. Adjust in this way until the position of aluminum plate 2 is directly above the positioning device.

[0041] Please see Figure 2In this embodiment, the left side of the horizontal plate 57 is threaded with several fixing bolts 60, and the left side of the vertical plate 33 is provided with several vertical through holes 61. The fixing bolts 60 are located in the corresponding vertical through holes 61. Before adjusting the vertical position of the vertical rod 50, the fixing bolts 60 are loosened first, and then the vertical position of the vertical rod 50 is adjusted by adjusting bolts 59. After adjustment, the fixing bolts 60 are tightened to lock the position of the vertical rod 50. The fixing bolts 60 play an auxiliary role in fixing the position of the vertical rod 50.

[0042] In this embodiment, the material handling device includes a material handling plate 62, which is slidably disposed on the upper surface of the positioning plate 7 in the front-back direction. A material dropping hole 63 is provided on the upper surface of the material handling plate 62. A plurality of sliding grooves 64 corresponding to the positioning blocks 10 are provided on the inner sidewall of the material handling plate 62. Each positioning block 10 is located within its corresponding sliding groove 64 and slidably connected to the material handling plate 62. A positioning spring 65 is fixedly disposed on the outer side of each positioning block 10, with the outer end of the positioning spring 65 fixedly disposed to the inner sidewall of the sliding groove 64. A limit block 66 is fixedly disposed on the outer side of the positioning block 10. The inner sidewall of the sliding groove 64 of the positioning plate 7 is... A limiting groove 67 adapted to the limiting block 66 is provided. The positioning block 10 is slidably connected to the material picking plate 62 through the limiting block 66 and the limiting groove 67. The positioning spring 65 always drives the positioning block 10 to move inward until the limiting block 66 is limited by the limiting groove 67. The positioning block 10 is L-shaped. When the positioning block 10 moves to the innermost position, the inner side of the vertical part of the positioning block 10 contacts the aluminum plate 2 to achieve positioning of the aluminum plate 2. The inner side of the horizontal part of the positioning block 10 coincides with the inner side wall of the through hole 9 of the positioning plate 7, without interfering with the column 4 entering the through hole 9 of the positioning plate 7 and then entering between each positioning block 10.

[0043] In this embodiment, a material box 68 is fixedly provided on the front side of the base 1, and a handle 69 is fixedly provided on the front side of the material picking plate 62. The material picking plate 62 is slidably connected to the upper end face of the positioning plate 7 and the upper end face of the material box 68. A wedge block 70 corresponding to the positioning block 10 is fixedly provided on the inner side wall of the material box 68. A notch 71 adapted to the wedge block 70 is opened on the lower end face of the positioning block 10. The inner side wall of the notch 71 is a third inclined surface 72. The height of the wedge block 70 is greater than the upper end face of the material box 68. An avoidance channel 73 is opened on the lower end face of the material picking plate 62 in the front-back direction. When in use, as the pressure block 5 is raised, the positioning plate 7 moves upward accordingly. When the positioning plate 7 contacts the nut 12 at the top of the guide post 8, the pressure block 5 continues to move upward and disengages from the positioning plate 7. At this time, the operator pulls the material-retrieving plate 62 forward through the handle 69. The material-retrieving plate 62 drives the pressed shell 3 forward through the positioning block 10. When the material-retrieving plate 62 moves to the upper end face of the material box 68, the wedge block 70 enters the notch 71 of the positioning block 10 and forces the positioning block 10 to move outward through the third inclined surface 72 of the notch 71 until the horizontal part of the positioning block 10 retracts into the slide groove 64. At this time, the shell 3 loses the support of the positioning block 10 and falls downward from the material drop hole 63 of the material-retrieving plate 62 into the material box 68, achieving the purpose of retrieving the material. Then the material-retrieving plate 62 is pushed back to the upper end face of the positioning plate 7. A positioning strip 74 is fixedly provided on the upper end face of the positioning plate 7. When the material taking plate 62 moves backward and the upper end face of the positioning plate 7 touches the positioning strip 74, it means that the material taking plate 62 has returned to its original position.

[0044] In this embodiment, a first hydraulic telescopic rod (not shown in the figure) is fixedly provided on the front side of the material picking plate 62. The first hydraulic telescopic rod drives the material picking plate 62 to move back and forth through program control to achieve the purpose of picking up materials and resetting. The first hydraulic telescopic rod serves as a parallel embodiment of the handle 69, which further improves automation and optimizes the operation process.

[0045] Please see Figure 20 In this embodiment, a stop block 75 higher than the upper end face of the material box 68 is fixedly provided on the inner side wall of the rear side of the upper end face of the material box 68, and an avoidance groove 76 is provided on the front side of the lower end face of the material picking plate 62. When the material picking plate 62 moves forward, the stop block 75 passes through the avoidance groove 76. When the material picking plate 62 continues to move forward, the positioning block 10 on the rear side of the material picking plate 62 is blocked by the stop block 75, causing the positioning block 10 to move into the slide groove 64 until the positioning block 10 retracts into the slide groove 64, and the stop block 75 is also located in the slide groove 64. At this time, the positioning blocks 10 on both sides and the rear side of the material picking plate 62 are all retracted into the slide groove 64, and the shell 3 is only supported by the positioning block 10 on the front side of the material picking plate 62. Therefore, the shell 3 will fall downward into the material box 68.

[0046] In this embodiment, a plurality of support columns 77 are fixedly provided on the upper end surface of the base 1, and each support column 77 is fixedly provided on the lower end surface of the top plate 78. The driving device includes a second hydraulic telescopic rod 79 fixedly provided with the top plate 78. The output end of the second hydraulic telescopic rod 79 is fixedly provided with the upper end surface of the pressure block 5. The extension and retraction of the second hydraulic telescopic rod 79 drives the pressure block 5 to move up and down.

[0047] In this embodiment, a control panel 80 is fixedly installed on the front side of the workbench 13, and start and stop buttons are installed on the control panel 80; a material table 81 is provided on the front side of the workbench 13, and several aluminum plates 2 to be stamped are placed on the upper surface of the material table 81.

[0048] In this embodiment, a base 82 is fixedly installed on the left side of the workbench 13, and a third hydraulic telescopic rod 83 is fixedly installed on the upper end of the base 82. The output shaft of the third hydraulic telescopic rod 83 is fixedly installed with the left end of the feeding rod 16. A hollow bolt 84 is threadedly connected to the left end of the third hydraulic telescopic rod 83. When it is necessary to use the third hydraulic telescopic rod 83 to directly drive the feeding rod 16, the hollow bolt 84 is tightened so that the hollow bolt 84 seals the left end of the third hydraulic telescopic rod 83. At this time, the third hydraulic telescopic rod 83 can be used normally. Then, the horizontal plate 57 is removed from the pressure block 5, and the adjustment is removed from the vertical rod 50. Bolt 59 can be used to remove the horizontal plate 57 and adjusting bolt 59; at this time, the feeding rod 16 can be moved left and right directly by extending and retracting the third hydraulic telescopic rod 83. The third hydraulic telescopic rod 83 is the second driving method for the feeding rod 16, used during machine debugging. The feeding rod 16 is moved left and right directly by the third hydraulic telescopic rod 83, which facilitates observation of the descent speed of the picking rod 17. At this time, the pressure block 5 can remain stationary; when the pressure block 5 needs to drive the feeding rod 16 to move left and right, the third hydraulic telescopic rod 83 needs to be disabled. The operation method is to rotate the hollow bolt 84 so that the hollow bolt 84 moves to the left, such as Figure 4 In the state shown, the interior of the cylinder of the third hydraulic telescopic rod 83 is connected to the outside through the hollow bolt 84. The upper end face of the hollow bolt 84 is provided with a vent hole 85. The interior of the cylinder of the third hydraulic telescopic rod 83 is connected to the outside through the vent hole 85. At this time, the pressure block 5 moves up and down, which drives the feeding rod 16 to move left and right through the vertical rod 50. The left and right movement of the feeding rod 16 drives the output shaft of the third hydraulic telescopic rod 83 to move left and right in the cylinder. Since the interior of the cylinder is connected to the outside through the hollow bolt 84, the left and right movement of the output shaft of the third hydraulic telescopic rod 83 is invalid and does not hinder the left and right movement of the feeding rod 16.

[0049] A stamping method based on an automatic aluminum product stamping device includes: A) placing an aluminum plate 2 on a material table 81 into a feeding position 14; B) pressing a start button, causing the second hydraulic telescopic rod 79 to drive the pressure block 5 downwards for a pneumatic press, while the pressure block 5 presses downwards, causing the feeding rod 16 to move to the left, and the feeding rod 16 causes the picking rod 17 to move to the left above the feeding position 14, whereupon the vacuum generator 43 generates a vacuum, and the suction nozzle 18 picks up the aluminum plate 2; C) the second hydraulic telescopic rod 79 drives the pressure block 5 upwards; D) the upward movement of the pressure block 5 drives... The feeding rod 16 moves to the right, which drives the picking rod 17 to move to the right. The aluminum plate 2 is placed in the positioning plate 7 device by the picking rod 17. The vacuum generator 43 stops, and the suction nozzle 18 disengages from the aluminum plate 2. E. The operator places the aluminum plate 2 in the discharge position 14. F. The pressure block 5 presses down and cooperates with the column 4 to press the aluminum plate 2 into the shell 3. G. The pressure block 5 is lifted, and the operator pulls the picking plate 62 forward through the handle 69 to move it to the upper end of the material box 68. The shell 3 automatically falls into the material box 68. The next steps are DEF GD EF G- DEFG.
