Description

Technical Field

[0001] The invention discloses a button cap punching and forming device, belonging to the technical field of button production equipment. Background Art

[0002] Buttons can be divided into two categories based on their materials: metal buttons and resin buttons. Resin buttons are processed through a series of operations such as batching, forming, cutting, drilling, grinding and polishing, while metal buttons are mainly punched using a punching machine. The metal strip is punched and formed in steps by replacing different punch dies, and the punched part is punched off to form a metal button. Most existing metal buttons are riveted, and their decorative surfaces cannot be replaced according to the needs of different products. Therefore, our company has designed a button cap with a detachable decorative surface, such as Figure 1 and Figure 2 As shown, it comprises three parts, a buckle 2, a decorative card 1 and a spring. The decorative card 1 is connected to the card hole on the buckle 2 by means of a spring clip. The surface of the decorative card 1 can be processed into different patterns by etching, electroplating or inlaying to meet various display needs. Since the buckle 2 and the decorative card 1 are different parts, if they are processed and formed separately, two sets of punching equipment need to be designed separately to form the buckle 2 and the decorative card 1 respectively, which will increase the design and labor costs.

The second fixed frame 5 is installed on the base 14, and the second fixed frame 5 is provided with a second cylinder 6 for driving the second movable plate 54 to vertically lift and lower. The first forming punch 53 and the second forming punch 50 are both installed on the second movable plate 54. Two groups of second pressing pieces 17 are also provided on the second movable plate 54. The blanking die 13 is provided with a first blanking groove 38, a first forming groove 36, and a second The punching groove 34 and the second molding groove 35, the first punching groove 38 and the first molding groove 36 are used to mold the buckle 2, the second punching groove 34 and the second molding groove 35 are used to mold the decorative card 1, the first molding groove 36 and the second molding groove 35 are both provided with a pushing piece 37, and the first molding groove 36 is also provided with a molding boss 46, and the base 14 is provided with a driving piece 15 for driving the two punching dies 13 to slide horizontally, and the sliding direction of the punching dies 13 is set perpendicular to the direction of the plate 12, and the base 14 is provided with a blanking hole 8 at the position corresponding to the two groups of molding devices 16.

[0027] The first pressing member 21 includes a pressing plate 26, a first limiting bolt 29 and a first spring 30. At least two first limiting bolts 29 and first springs 30 are provided. One end of the first limiting bolt 29 passes through the first movable plate 27 and is fixedly connected to the pressing plate 26. The first spring 30 is sleeved on the outer side of the first limiting bolt 29, and the two ends of the first spring 30 respectively contact the pressing plate 26 and the first movable plate 27. When punching and blanking the sheet 12, the pressing plate 26 will first move downward synchronously with the first movable plate 27. When the pressing plate 26 presses the sheet 12, the pressing plate 26 cannot continue to move. At this time, the first movable plate 27 drives the punching punch and the punching punch to continue to move downward, so that the first spring 30 is continuously compressed. In this way, the pressing plate 26 can play a pressing role on the sheet 12, and can prevent the sheet 12 from moving during punching and blanking.

[0028] The second pressing member 17 includes a clamping sleeve 51, a second limiting bolt 52 and a second spring 55. One side of the two clamping sleeves 51 cooperates with the first punching groove 38 and the second punching groove 34 respectively. One end of the second limiting bolt 52 passes through the second movable plate 54 and is fixedly connected with the clamping sleeve 51. The second spring 55 is sleeved on the outer side of the second limiting bolt 52, and the two ends of the second spring 55 respectively contact the second movable plate 54 and the clamping sleeve 51. One end of the first forming punch 53 and the second forming punch 50 are fixedly connected to the second movable plate 54, and the other end passes through the two clamping sleeves 51 respectively. After the sheet 12 is punched and formed, two sheet bodies are formed, such as Figure 3 As shown in A1 and A2 in the figure, they are respectively located in the first punching groove 38 and the second punching groove 34. During bending, the second movable plate 54, driven by the second cylinder 6, enables the first forming punch 53, the second forming punch 50 and the clamping sleeve 51 to keep moving downward synchronously. When the clamping sleeve 51 contacts the sheet body, the clamping sleeve 51 cannot continue to move downward. At this time, the first forming punch 53 and the second forming punch 50 continue to move downward, so that the second spring 55 is continuously compressed. The pressure applied by the clamping sleeve 51 to the sheet body can keep the sheet body from excessive warping during bending, thereby ensuring that the two sheets are smoothly bent to form the decorative card 1 and the buckle 2.

[0029] The two clamping sleeves 51 are both fixedly mounted with an electromagnetic induction coil 49, which is sleeved on the outside of the first forming convex die 53 and the second forming convex die 50. The electromagnetic induction coil 49 can move synchronously with the clamping sleeve 51, and will generate a magnetic field during the power-on process, and generate a magnetic attraction to the formed decorative card 1 and buckle 2. In order to increase the magnetic attraction, an iron core can be added to the electromagnetic induction coil 49, so that after the decorative card 1 and buckle 2 are formed, when the clamping sleeve 51 is reset, the decorative card 1 can be moved. And the buckle ring 2 brings out the first molding groove 36 and the second molding groove 35. In order to prevent the decorative card 1 and the buckle ring 2 from being unable to separate from the first molding groove 36 and the second molding groove 35 due to magnetic force, thereby successfully completing the blanking process, the clamping sleeve 51 is made of non-metallic material, and the surfaces of the first molding punch 53, the second molding punch 50, the molding boss 46 and the punching die 13 are coated with anti-magnetic material. When the electromagnetic induction coil 49 is powered off, the magnetic attraction disappears, so that the buckle ring 2 and the decorative card 1 can smoothly fall from the blanking hole 8.

[0030] Guide posts 7 are provided on the first movable plate 27 and the second movable plate 54, and guide holes 33 cooperating with the guide posts 7 are provided on the punching die 9 and the shearing die 13. During the punching and shearing process, the guide posts 7 on the first movable plate 27 and the second movable plate 54 are inserted downward into the guide holes 33, which can ensure the relative positions of the punching punch and the punching die 9, and the shearing punch and the shearing die 13, thereby smoothly realizing punching and shearing.

[0031] The pushing member 37 includes a pushing plate 48, a third limiting bolt 47 and a third spring 45. The two pushing plates 48 are respectively located in the first molding groove 36 and the second molding groove 35. One end of the third limiting bolt 47 passes through the punching die 13 and is fixedly connected to the pushing plate 48. The first spring 30 is sleeved on the outer side of the third limiting bolt 47 and applies an upward force to the pushing plate 48. After the buckle 2 and the decorative card 1 are formed, the second movable plate 54 drives the first molding punch 53 and the second molding punch 50 to move upward, and the pushing plate 48 is reset upward under the action of the third spring 45, so that the buckle 2 and the decorative card 1 can be subjected to an upward force so that they will not be stuck in the first molding groove 36 and the second molding groove 35.

[0032] The driving member 15 includes a first motor 23, a screw 19 and a guide rod 20. Two mounting blocks 18 are arranged on the base 14. The two ends of the screw 19 and the guide rod 20 are respectively connected to the two mounting blocks 18. The two punching dies 13 are threadedly connected to the screw 19, and the punching dies 13 are slidably connected to the guide rod 20. The output shaft of the first motor 23 is fixedly connected to one end of the screw 19. When the first motor 23 drives the screw 19 to rotate, the two punching dies 13 can slide horizontally so that their positions can be changed. In this way, one punching die 13 can successfully complete the punching process with the first punching punch 24 and the second punching punch 25, and the other punching die 13 can successfully complete the bending process with the first forming punch 53 and the second forming punch 50. The two processes can be carried out simultaneously and the waiting time can be saved.

[0033] The conveying mechanism 10 includes a second motor 40, a driving gear 44, a driven gear 43 and two conveying rollers 42. A fixed block 41 is provided on the mounting seat 11. The two conveying rollers 42 are rotatably arranged on the fixed block 41 in the form of an upper and lower roller pair. The output shaft of the second motor 40 is fixedly connected to one end of one of the conveying rollers 42. The driving gear 44 and the driven gear 43 are respectively fixed to the ends of the two conveying rollers 42, and the driving gear 44 and the driven gear 43 are meshed for transmission. When the second motor 40 drives one of the conveying rollers 42 to rotate, the other conveying roller 42 can be driven to rotate by relying on the meshing of the driving gear 44 and the driven gear 43. The two conveying rollers 42 can generate a conveying force on the plate 12, thereby realizing fixed-distance feeding and conveying.

[0034] Working principle: the sheet 12 is conveyed to one side by the conveying mechanism 10 and moves at a fixed distance. At this time, one of the punching dies 13 is located directly below the first punching punch 24 and the second punching punch 25, and the first cylinder 3 drives the first movable plate 27 to move downward. The pressing plate 26 first presses the sheet 12, and then the first punching punch 31 and the second punching punch 28 punch out the excess waste at two positions of the sheet 12. The first punching punch 24 and the second punching punch 25 cooperate with the punching die 13 to punch out two sheets of different shapes at the position after the sheet 12 is punched. Then the first cylinder 3 The first movable plate 27 is driven to reset, and the sheet remains in the punching die 13 under the action of the pressing plate 26. Then the driving member 15 drives the two punching dies 13 to slide horizontally, and one of the punching dies 13 drives the sheet to move below the first forming punch 53 and the second forming punch 50. Then the second cylinder 6 drives the second movable plate 54 to move downward, so that the pressing sleeve 51 first presses the sheet, and then the first forming punch 53 and the second forming punch 50 apply force to the middle part of the sheet, so that the sheet is bent and cooperates with the first forming groove 36 and the second forming groove 35 to form the buckle 2 and the decorative card 1, as shown in FIG. Figure 3As shown, the second movable plate 54 is finally reset upward. Since the buckle 2 and the decorative card 1 always keep in contact with the clamping sleeve 51 under the action of the push plate 48, when the clamping sleeve 51 is ready to separate from the punching die 13, the electromagnetic induction coil 49 is energized to generate a magnetic field, and generates a magnetic attraction force on the buckle 2 and the decorative card 1, so that the buckle 2 and the decorative card 1 move upward to the highest point with the second movable plate 54, thereby avoiding the two from remaining in the first molding groove 36 and the second molding groove 35 and affecting the subsequent punching process, and after the next horizontal sliding of the two punching dies 13, the electromagnetic induction coil 49 is de-energized, and the buckle 2 and the decorative card 1 will automatically fall from the blanking hole 8.
