Description

Technical Field

[0001] This invention relates to the field of metal sleeve processing technology, specifically to an automated equipment for feeding and punching metal sleeves. Background Technology

[0002] In the processing of metal sleeves, it is necessary to punch equally spaced holes around the upper and lower halves of the metal sleeve blank. For this processing, the existing technology usually relies on manual labor and a semi-automatic method such as a punching machine. That is, the operator places the metal sleeve in a designed fixture, places the fixture in the working area of ​​the punching machine, and the operator operates the punching machine to punch holes on the surface of the metal sleeve. The punching machine can only punch one hole on the surface of the metal sleeve in one punching action. In order to punch holes around the circumference, the operator needs to rotate the fixture, which will drive the metal sleeve to rotate, and the punching mechanism will punch again, and so on, repeating the cycle.

[0003] The above-mentioned method of punching a circle of holes on the surface of a metal sleeve is not only inefficient and costly, but also requires skilled and experienced workers, pre-job training, and workers to maintain a consistent punching rhythm. Otherwise, it will damage the metal sleeve blank and result in a low yield. Therefore, we propose an automated metal sleeve feeding and punching equipment. Summary of the Invention

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figure 1This invention provides a technical solution: an automated metal sleeve feeding and punching device, comprising a cabinet 1 and a turntable 2. The turntable 2 is installed on the upper part of the cabinet 1, capable of carrying a plurality of metal sleeves 7, and capable of intermittently rotating at a fixed angle. A feeding module 3, a first punching module 4, a second punching module 5, and a discharging module 6 are sequentially installed on the upper part of the cabinet 1 and around the turntable 2 in a fixed direction. The first punching module 4 and the second punching module 5 have identical structures. The feeding module 3 can fix the metal sleeves 7 in the working position of the turntable 2 by insertion. The first punching module 4 can punch a plurality of equally spaced holes around the lower half of the metal sleeve 7. The second punching module 5 can punch a plurality of equally spaced holes around the upper half of the metal sleeve 7. The discharging module 6 can eject and collect the punched metal sleeves 7 from the working position of the turntable 2.

[0046] When this automated metal sleeve feeding and punching equipment is in operation, the turntable 2 has workstation holes on each circumference to accommodate metal sleeves 7. The feeding module 3 can sequentially feed several metal sleeves 7 to the turntable 2. The turntable 2 is driven by a servo motor or a stepper motor, which can intermittently drive the turntable 2 to rotate, and each rotation is at a fixed angle. The angle is determined by the number of workstation holes. For example, if there are 20 workstation holes, then the angle of rotation of the turntable 2 each time is 18°. The metal sleeves 7 are sequentially fixed in the workstation holes. After entering the interior, the turntable 2 rotates. When it rotates to the processing area of ​​the first punching module 4, the first punching module 4 can punch out several holes in the lower half of the metal sleeve 7. Similarly, when the turntable 2 drives the metal sleeve 7 to rotate to the processing area of ​​the second punching module 5, the second punching module 5 can punch out several holes in the upper half of the metal sleeve 7. After punching is completed, it continues to rotate with the turntable 2. When it reaches the position of the unloading module 6, the unloading module 6 pushes out the punched metal sleeve 7, thus completing the whole process.

[0047] Please see Figure 6-7 The feeding module 3 includes a vibrating disc 31, a direct vibrator 32, and a top feeding mechanism 33. The inlet of the direct vibrator 32 is connected to the outlet of the vibrating disc 31, and the inlet of the top feeding mechanism 33 is connected to the outlet of the direct vibrator 32. The top feeding mechanism 33 includes a bracket 331. A top feeding cylinder 332 is fixedly installed on the lower part of the bracket 331, and a transition seat 333 is fixedly installed on the upper part of the bracket 331. A top feeding cavity 334 is reserved on the end face of the transition seat 333 facing the outlet of the direct vibrator 32. The telescopic end of the top feeding cylinder 332 passes through the transition seat 333 and extends into the interior of the top feeding cavity 334.

[0048] When the feeding module 3 is working, it pours the metal sleeve 7 into the vibrating plate 31. After continuous vibration of the vibrating plate 31, the metal sleeve 7 is neatly discharged from the outlet of the vibrating plate 31 and enters the track of the straight vibrator 32. After being transported by the track of the straight vibrator 32, it enters the top material cavity 334. At this time, the top material cylinder 332 extends, and its telescopic end lifts the metal sleeve 7 and inserts it into the hole 25.

[0049] Please see Figure 2-5 The turntable 2 has adaptive clamping modules 21 installed on its edges and pre-drilled workstation holes. Metal sleeves 7 are located in the workstation holes and are clamped and fixed in the workstation holes by the adaptive clamping modules 21. The adaptive clamping module 21 includes a support body 211 fixed in the pre-drilled holes of the turntable 2. A through hole 213 is formed inside the support body 211, and an abutment 214 is slidably connected inside the through hole 213. A back plate 215 is fixedly connected to the back of the support body 211. A spring 216 is connected between the abutment 214 and the back plate 215. A roller 217 is rotatably connected inside the abutment 214, and the roller 217 abuts against the surface of the metal sleeve 7. The turntable 2 has holes 22, 23, 24, 25, 26, and 27 respectively. Holes 24 and 25 are connected. The support 211 is located in hole 22, the abutment 214 is located in hole 23, the roller 217 is located in hole 24, and the metal sleeve 7 is located in hole 25. The bottom end of the support 211 is fixedly connected to the base plate 212. The adjacent end faces of the back plate 215 and the abutment 214 are all provided with spring limiting grooves 218. The two ends of the spring 216 are located in the spring limiting grooves 218. In 8, the upper part of the abutment 214 is integrally connected to the limiting protrusion 219, and the ends of the abutment 214 are respectively provided with roller mounting groove 2110 and pin hole 2111. The roller mounting groove 2110 and pin hole 2111 are connected. The roller 217 is located inside the roller mounting groove 2110. A pin 2112 is inserted inside the pin hole 2111, which allows the roller 217 to rotate inside the roller mounting groove 2110.

[0050] After the metal sleeve 7 is inserted into the hole 25, the roller 217 will rotate during the insertion process. The metal sleeve 7 will contact the roller 217 and squeeze the roller 217, causing the abutment 214 connected to the roller 217 to move. The movement of the abutment 214 causes the spring 216 to contract. When the metal sleeve 7 is inserted into place, the spring 216 extends and pushes the abutment 214 to move inside the through hole 213 in the opposite direction. The thrust generated by the spring 216 will act on the roller 217, so that the roller 217, together with the turntable 2, clamps the metal sleeve 7.

[0051] Please see Figure 8-16The first punching module 4 includes a frame body 41, a punching cylinder 42 fixedly installed on the upper part of the frame body 41, an upper die assembly 43 movably disposed inside the frame body 41 and connected to the telescopic end of the punching cylinder 42, a lower die assembly 44 fixedly installed at the bottom of the inside of the frame body 41, a guide rod 45 connected between the upper die assembly 43 and the lower die assembly 44, and a buffer spring 46 sleeved on the outside of the guide rod 45.

[0052] The upper mold assembly 43 includes an upper mold base 431. The bottom end of the upper mold base 431 is fixedly connected to a pressure head 432, several pressure rods 433, and several trigger rods 434. Each trigger rod 434 has a slope 435 at its bottom end. The pressure head 432 is located at the center of the bottom end of the upper mold base 431. Several pressure rods 433 are distributed around the upper mold base 431, and several trigger rods 434 are distributed around the pressure rods 433. A rod sleeve 436 is fixedly connected inside the upper mold base 431, and the top end of the guide rod 45 slides inside the rod sleeve 436.

[0053] Additionally, the lower die assembly 44 includes a stamping plate 446, in which a bushing 447 is fixedly disposed and a slider 4465 is movably disposed. A floating limit rod 4411 and a shaft core 4412 are movably disposed inside the bushing 447. Several stamping guide holes 4410 are provided on the sides of both the bushing 447 and the shaft core 4412. An inclined surface 4466 adapted to the inclined surface 435 is provided at the outer end of the slider 4465. A punch head 4468 is fixedly connected inside the slider 4465. The lower die assembly 44 also includes a lower die base 441. A stop plate 442 is fixedly connected to the upper part of the die base 441. Several spring limiting holes 443 are provided at the top of the stop plate 442. A return spring 445 is installed inside each spring limiting hole 443. A middle layer plate 444 is fixedly connected to the top of the lower die base 441. Each return spring 445 extends above the middle layer plate 444 and abuts against the floating limiting rod 4411 and the shaft core 4412. A stamping plate 446 is fixedly installed on the upper part of the middle layer plate 444. A bushing 447 is fixed in the stamping plate 446. A center opening in the bushing 447 is used to accommodate... The shaft core 4412 has a second through hole 449, and the inside of the bushing 447 has several first through holes 448 connected around the second through hole 449 to accommodate the floating limit rod 4411. The side of the stamping plate 446 has several slots 4461, and the top has a bushing hole 4462 and several trigger holes 4463 distributed around the bushing hole 4462. The slots 4461, bushing hole 4462 and trigger holes 4463 are all connected. The slider 4465 is located in the channel connecting the bushing hole 4462 and the trigger holes 4463. A spring hanger 4467 is connected through the interior of 5. The end of the punch head 4468 is fixedly connected to the spring hanger 4467. A baffle 4464 is fixedly installed inside the trigger hole 4463 and on one side of the slider 4465. A spring hanger 4469 is installed on the side of the stamping plate 446 and at the position corresponding to the slot 4461. A reset spring 44610 is connected between the spring hanger 4469 and the spring hanger 4467. A through hole is reserved inside the baffle 4464, through which the reset spring 44610 passes.

[0054] When the first punching module 4 is working, the metal sleeve 7 is located in the station of the turntable 2. When the turntable 2 carries the metal sleeve 7 and rotates to the position between the floating limit rod 4411 and the shaft core 4412, it stops. At this time, the punching cylinder 42 pushes the upper die base 431 to move down. During the downward movement, the pressure head 432, the pressure rod 433, and the trigger rod 434 will simultaneously squeeze the metal sleeve 7, the floating limit rod 4411, and the slider 4465 downward, causing the metal sleeve 7 to be sleeved on the outside of the shaft core 4412, so that the metal sleeve 7 is fixed between the shaft core 4412 and several floating limit rods 4411. At this time, several return springs 445 are also in a compressed state. Since the bottom end of the trigger rod 434 is provided with a slope 435, and the end of the slider 4465 is provided with a slope, the metal sleeve 7 is fixed between the shaft core 4412 and several floating limit rods 4411. At this time, several return springs 445 are also in a compressed state. Therefore, when the two inclined surfaces abut, they will give the slider 4465 a push towards the bushing 447. At the same time, the return spring 44610 will be stretched. When the slider 4465 moves towards the bushing 447, the punch head 4468 inside it will also move synchronously. During the movement, it enters the interior of the bushing 447 through the punching guide hole 4410 opened on the side of the bushing 447, and finally puts the impact force on the metal sleeve 7, so that the side of the metal sleeve 7 is punched. The shaft core 4412 is a hollow structure, and with the punching guide hole 4410 also opened on the side, the circular waste generated by the punching will be discharged through the holes reserved in the hollow structure of the shaft core 4412, the middle plate 444, the abutment plate 442 and the lower die base 441.

[0055] After a punching operation is completed, the punching cylinder 42 drives the upper die base 431, the pressure head 32, the pressure rod 433, and the trigger rod 434 to move upward as a whole. At this time, the metal sleeve 7, the floating limit rod 4411, and the slider 4465 are no longer squeezed. The first return spring 445 and the second return spring 44610 will both return to their original positions. The first return spring 445 will push the metal sleeve 7, the shaft core 4412, and the floating limit rod 4411 upward, so that the punched metal sleeve 7 returns to the station of the turntable. The turntable 2 takes away the punched metal sleeve 7 by rotating and carries the next metal sleeve 7 to be punched between the floating limit rod 4411 and the shaft core 4412. The return of the second return spring 44610 will pull the slider 4465 and the punching head 4468 to return to their original positions. By repeating the above process, multiple holes can be punched at equal intervals on the side of the metal sleeve 5 in batches.

[0056] Please see Figure 17 The unloading module 6 includes a bracket 61 installed on the upper part of the equipment cabinet 1 and an unloading chute 62. An unloading cylinder 63 is fixedly installed on the top of the bracket 61. The unloading cylinder 63 is located above the turntable 2, and a push rod 64 is fixedly connected to the telescopic end of the unloading cylinder 63. The push rod 64 can push the metal sleeve 7 out and let it fall on the unloading chute 62.

[0057] When the unloading module 6 is working, when the turntable 2 pauses, the push rod 64 is exactly above the metal sleeve 7. At this time, the unloading cylinder 63 extends and pushes the push rod 64 down, which can push the metal sleeve 7 out of the turntable 2 and onto the slide groove 62.

[0058] In summary, this automated metal sleeve feeding and punching equipment, by setting up a turntable 2, a feeding module 3, a first punching module 4, a second punching module 5, and a unloading module 6, can automatically complete the punching process on metal sleeves without manual intervention through the cooperation of these modules. Compared with the existing semi-automatic method of manual labor and machinery, the fully automated punching process on metal sleeves can not only significantly improve the processing efficiency of metal sleeves and reduce the punching cost, but also improve the yield rate of punched metal sleeves. It is suitable for punching large batches of metal sleeves.
