Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and specifically provides a metal shell cutting equipment and a processing method for switch production. Background Art

[0002] A switch is a network device that forwards data based on the MAC (Media Access Control) address. Its core function is to establish an exclusive signal path to achieve efficient and directional data transmission, avoiding the conflict problems of traditional shared networks (such as hubs). Among them, the outer shell of the switch is usually made of a metal shell with better performance. During the production of the metal shell of the switch, there will be excess waste parts at the edges of the just processed metal shell. Manufacturers usually use cutting equipment to cut off these waste parts; Chinese Patent CN219358059U discloses a metal shell cutting and inserting machine. The prior art uses a cutting knife to cut the waste part of the metal shell, with high working efficiency. At the same time, a pressing plate structure is adopted to avoid damage to the metal shell caused by uneven cutting during the cutting process of the cutting knife. However, the prior art is only applicable to metal shells that need to cut waste on one side. When dealing with metal shells with waste on all four sides, it is necessary to pause the equipment after one cutting, take out the metal shell, reverse it to face the cutting knife on the other side, and then put the metal shell back. To complete the cutting of the waste on the four sides of a metal shell, it is necessary to pause the equipment multiple times for clamping and adjustment, which is very time-consuming and laborious, thus reducing the processing efficiency of the metal shell.

After completing the cutting of the waste materials on this side, the loading platform returns with the metal shell. During the return process, the push rod pushes the steering rod to extend the sleeve, releases the restriction of the limiting groove on the steering rod, so that the support frame lifts the metal shell, and the driving rack is engaged with the driving gear, thereby driving the steering rod to rotate ninety degrees, so that the other side of the metal shell faces the cutting component, so that the equipment can complete the steering of the metal shell without stopping the machine, and there is no need to stop the equipment for clamping and adjustment during the processing, which is very time-saving and labor-saving, thereby improving the processing efficiency of the metal shell.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0019] Please refer to Figures 1 - 8, a metal shell cutting device and a processing method for switch production, comprising a machine tool 1 and two guide rails 11 laid on both sides of the machine tool 1, characterized in that: a feeding mechanism 2, a positioning component 4 and a cutting component 5 are arranged on the machine tool 1. The feeding mechanism 2 includes a carrier table 21 and a steering component 3. The carrier table 21 is assembled on the guide rail 11 for placing the metal shell and conveying the metal shell towards the cutting component 5. The steering component 3 includes a push rod 33 and a support frame 37. The push rod 33 is installed at the bottom of the carrier table 21. The upper end of the push rod 33 is connected with a steering rod 34. The steering rod 34 penetrates through the carrier table 21 upwards. The top end of the steering rod 34 is connected with a support frame 37. The support frame 37 is used to support the metal shell placed on the carrier table 21. When the carrier table 21 drives the metal shell to return, the push rod 33 pushes the support frame 37 upwards to lift the metal shell. At the same time, the steering rod 34 drives the support frame 37 to rotate, so that the metal shell on the support frame 37 turns, and the side with waste faces the cutting component 5. The positioning component 4 includes a vertical frame 41 and a connecting rod 45. The vertical frame 41 is installed at the upper end of the carrier table 21. One end of the connecting rod 45 is assembled on the vertical frame 41, and a positioning plate 46 is installed at the other end of the connecting rod 45. When cutting the waste, the connecting rod 45 can drive the positioning plate 46 to move downwards to press the metal shell on the carrier table 21. The cutting component 5 includes a gantry 51 and a cutting knife 52. The gantry 51 is installed on the machine tool 1 at one end of the guide rail 11. The cutting knife 52 is installed on the gantry 51. The cutting knife 52 moves up and down on the gantry 51 to cut off the waste around the metal shell.

[0020] Among them, during use, the carrier table 21 in the initial state stops at one end of the guide rail 11 away from the cutting assembly 5. At this time, the connecting rod 45 is at the top of the vertical frame 41, so that there is enough space between the positioning plate 46 and the carrier table 21 to place the metal shell to be processed on the carrier table 21. When it is necessary to process the metal shell, first align the metal shell with the support frame 37 so that the metal shell covers the support frame 37. Among them, the size of the support frame 37 fits the internal size of the metal shell. When the metal shell covers the support frame 37, the bottom of the metal shell falls on the carrier table 21, while the top of the support frame 37 abuts against the top inside the metal shell, and the outer sides of the four sides of the support frame 37 are attached to the inner wall of the metal shell, thus supporting the metal shell on the carrier table 21. At this time, one side of the metal shell faces the cutting assembly 5. After placing the metal shell, the carrier table 21 moves on the guide rail 11 in the direction of the cutting assembly 5. During this process, the connecting rod 45 at the top of the vertical frame 41 moves downward, so that the positioning plate 46 on the connecting rod 45 falls on the top of the metal shell, thus pressing the metal shell on the carrier table 21. The metal shell is fixed on the carrier table 21 through the cooperation of the support frame 37 and the positioning plate 46. When the carrier table 21 transports the metal shell under the gantry 51, the waste on the side of the metal shell facing the gantry 51 at this time is directly below the cutting knife 52. At this time, the carrier table 21 pauses to move, and the cutting knife 52 on the gantry 51 drops to cut off the waste on the lower metal shell. After cutting off the waste on this side of the metal shell, during this process, the metal shell on the carrier table 21 is supported by the support frame 37 inside and positioned by the positioning plate 46 outside, thus preventing the metal shell from shifting or deforming when the cutting knife 52 cuts the waste, thereby ensuring the processing quality of the metal shell. The cutting knife 52 rises back to the top of the gantry 51, and at the same time, the carrier table 21 starts and moves away from the gantry 51 for the return journey. During the return journey, the connecting rod 45 moves up to the top of the vertical frame 41, so that the positioning plate 46 disengages from the metal shell. Subsequently, the push rod 33 moves up, thus pushing up the support frame 37 through the steering rod 34, making the metal shell suspended on the carrier table 21. Then the steering rod 34 drives the support frame 37 to rotate, turning the other side of the metal shell towards the cutting assembly 5. After the steering rod 34 completes the turning, the push rod 33 pulls the support frame 37 down through the steering rod 34, putting down the metal shell suspended on the carrier table 21, so that the bottom of the metal shell falls on the carrier table 21 again. At this time, the carrier table 21 has moved back to the initial position. Subsequently, the carrier table 21 starts to move in the reverse direction and transports the metal shell to under the gantry 51 again. At the same time, the connecting rod 45 at the top of the vertical frame 41 moves down again, and the positioning plate 46 is pressed on the top of the metal shell again to fix it. After the carrier table 21 transports the metal shell to under the gantry 51 again, the cutting knife 52 drops again to cut off the waste on the other side of the metal shell. When the waste on this side of the metal shell is completely cut off, the carrier table 21 makes a return journey again and repeats the above steps.Until the waste materials on the four sides of the metal shell are all cut off, after the processing of the metal shell is completed, when the loading platform 21 returns to the initial position, the processed metal shell is taken off, and the next metal shell to be processed is placed on the loading platform 21, and the above steps are repeated for processing.

[0021] The difference from the above embodiment is that a displacement groove 12 is formed on the machine tool 1. The displacement groove 12 is located between the two guide rails 11. A motor groove 13 is also formed on the machine tool 1. The motor groove 13 is located at one end of the machine tool 1 away from the cutting assembly 5 and between the displacement groove 12 and one of the guide rails 11. A photoelectric sensor 14 is fixedly installed on the machine tool 1. The photoelectric sensor 14 is located outside the guide rail 11.

[0022] The difference from the above embodiment is that the loading platform 21 is slidably installed on the guide rail 11 through a slider. A sliding groove 22 and a gear groove 23 are respectively formed on the lower side of the loading platform 21. The sliding groove 22 is located on the side of the loading platform 21 away from the motor groove 13 below, and the gear groove 23 is located on the side of the sliding groove 22. The gear groove 23 is communicated with the sliding groove 22. A connecting piece 24 is fixedly installed at the bottom of the loading platform 21. The connecting piece 24 is located on the side of the loading platform 21 close to the motor groove 13 below. A light blocking strip 25 is fixedly connected to the outside of the loading platform 21. The light blocking strip 25 corresponds to the photoelectric sensor 14.

[0023] The difference from the above embodiment is that the feeding mechanism 2 further includes a fixed seat 26, a driving motor 27 and a bearing seat 29. The fixed seat 26 is fixedly installed at the bottom of the loading platform 21. The fixed seat 26 is located directly below the gear groove 23. The driving motor 27 is fixedly installed in the motor groove 13. One end of the output shaft of the driving motor 27 is coaxially and fixedly connected to one end of the driving screw 28. The bearing seat 29 is fixedly installed at one end of the machine tool 1 close to the cutting assembly 5. The other end of the driving screw 28 is rotatably installed in the bearing seat 29. The connecting piece 24 is threadedly assembled on the driving screw 28. When the driving screw 28 rotates, the loading platform 21 is driven to move on the guide rail 11 through the connecting piece 24.

[0024] Among them, during the processing, after the metal shell is placed, the driving motor 27 drives the driving screw rod 28 to rotate forward. The rotation of the driving screw rod 28 drives the carrier table 21 to move towards the cutting assembly 5 on the guide rail 11 through the cooperation of the connecting member 24. When the carrier table 21 moves under the gantry 51, the driving motor 27 stops working. After the cutting knife 52 cuts off the waste material, the driving motor 27 starts again, drives the driving screw rod 28 to rotate reversely, and the rotation of the driving screw rod 28 drives the carrier table 21 to move away from the cutting assembly 5 on the guide rail 11 for the return journey. During the movement of the carrier table 21, the light shielding plate on the side of the carrier table 21 passes by the photoelectric sensor 14, thereby triggering the photoelectric sensor 14, and the photoelectric sensor 14 sends signals to the steering assembly 3 and the positioning assembly 4, so as to control the operation of the steering assembly 3 and the positioning assembly 4.

[0025] The difference from the above embodiment is that the steering assembly 3 further includes a pushing cylinder 31. The pushing cylinder 31 is fixedly installed on the fixed seat 26 and is located in the displacement groove 12. A socket 32 is fixedly installed on the output end of the pushing cylinder 31. Four limiting grooves 321 are formed in the socket 32, and the four limiting grooves 321 are evenly arranged in a circular shape on the socket 32. The push rod 33 slidably penetrates through the socket 32. The lower end of the push rod 33 is coaxially and fixedly connected to the output shaft of the pushing cylinder 31. The upper end of the push rod 33 is rotatably connected to the lower end of the steering rod 34. Four limiting blocks 35 are fixedly connected to the outer side of the lower end of the steering rod 34. The four limiting blocks 35 are evenly distributed on the outer side of the steering rod 34 and respectively correspond to the four limiting grooves 321. A driving gear 36 is coaxially fixedly connected to the steering rod 34, and the driving gear 36 corresponds to the gear groove 23. The support frame 37 is fixedly installed at the top end of the steering rod 34.

[0026] The difference from the above embodiment is that the steering assembly 3 further includes a support seat 38. The support seat 38 is fixedly installed on the machine tool 1 and is located on one side of the displacement groove 12. A driving rack 39 is fixedly installed at the upper end of the support frame 37. The driving rack 39 is located in the sliding groove 22, and the tooth surface of the driving rack 39 faces the driving gear 36.

[0027] Among them, the material pushing cylinder 31 is electrically connected to the photoelectric sensor 14. Initially, the material pushing cylinder 31 retracts its output shaft, so that the whole push rod 33 and the lower end of the steering rod 34 are received in the socket 32, and the four limit blocks 35 on the steering rod 34 are respectively engaged and stuck in the corresponding limit slots 321 to prevent the steering rod 34 from rotating. The driving gear 36 on the steering rod 34 disengages from the gear slot 23 and is located below the driving rack 39. When the carrier table 21 moves towards the cutting assembly 5, the driving rack 39 moves in the sliding slot 22, and the driving gear 36 on the steering rod 34 will pass below the driving rack 39 without contacting the driving rack 39. When the carrier table 21 returns, the light blocking plate on the side of the carrier table 21 triggers the photoelectric sensor 14 and sends a signal to the material pushing cylinder 31. After the positioning plate 46 rises, the material pushing cylinder 31 extends its output shaft, so that the push rod 33 pushes the support frame 37 to rise through the steering rod 34, so that the limit blocks 35 on the steering rod 34 disengage from the limit slots 321, and the driving gear 36 enters the gear slot 23 to correspond to the transmission rack, and the metal shell on the carrier table 21 is lifted and suspended on the carrier table 21. As the carrier table 21 continues to move, the driving rack 39 will pass by the side of the gear slot 23, so as to engage with the driving gear 36 in the gear slot 23 and drive the driving gear 36 to rotate. When the driving rack 39 passes through the gear slot 23, the driving rack 39 separates from the driving gear 36. At this time, the driving gear 36 drives the steering rod 34 to rotate by ninety degrees, so as to turn away the cut side of the metal shell, and the other side to be cut turns towards the cutting assembly 5. After the metal shell is turned, the material pushing cylinder 31 retracts its output shaft, so that the push rod 33 drives the steering rod 34 to move down, so as to put down the turned metal shell. At the same time, the whole push rod 33 and the lower end of the steering rod 34 are received in the socket 32 again, and the limit blocks 35 on the steering rod 34 are inserted into the limit slots 321 again, so as to prevent the steering rod 34 from rotating. At the same time, the driving gear 36 disengages from the gear slot 23 and will not contact the driving rack 39 during the next movement of the carrier table 21 towards the cutting assembly 5. After the other side of the metal shell is also cut, the carrier table 21 returns again, so as to repeat the above steps until the waste materials on the four sides of the metal shell are all cut off.

[0028] The difference from the above embodiment is that the vertical frame 41 is fixedly installed on the carrier table 21, on the side of the carrier table 21 away from the support frame 37. A lifting groove 42 is opened on the vertical frame 41. A servo motor 43 is fixedly installed at the top of the vertical frame 41. The output shaft of the servo motor 43 is coaxially and fixedly connected to the upper end of the lead screw 44. The lower end of the lead screw 44 is rotatably connected to the bottom of the lifting groove 42. One end of the connecting rod 45 is slidably installed in the lifting groove 42, and the end of the connecting rod 45 located in the lifting groove 42 is also assembled on the lead screw 44. The other end of the connecting rod 45 is fixedly connected to the positioning plate 46, and the positioning plate 46 is parallel to the carrier table 21.

[0029] Among them, the servo motor 43 is connected to the photoelectric sensor 14 through an electrical signal. When the carrier table 21 moves towards the cutting assembly 5 and triggers the photoelectric sensor 14, the photoelectric sensor 14 sends a signal to the servo motor 43. The servo motor 43 drives the lead screw 44 to rotate in the reverse direction, causing the connecting rod 45 at the top of the vertical frame 41 to move downward in the lifting groove 42, so that the positioning plate 46 at the other end of the connecting rod 45 presses on the metal shell, fixing the metal shell on the carrier table 21. When the carrier table 21 returns from the cutting assembly 5, the triggered photoelectric sensor 14 sends a signal to the servo motor 43 again, causing the servo motor 43 to start the pushing cylinder 31 one step earlier. At this time, the servo motor 43 drives the lead screw 44 to rotate in the forward direction, causing the connecting rod 45 to drive the positioning plate 46 to move upward in the lifting groove 42 and return to the top of the vertical frame 41. Embodiment 2

[0030] The difference from the above embodiment is that the gantry 51 is fixedly installed on the machine tool 1. Both sides of the gantry 51 are provided with sliding grooves 511. Both sides of the cutting tool 52 are fixedly connected with convex blocks 522. The convex blocks 522 are slidably installed in the sliding grooves 511. A driving cylinder 53 is fixedly installed on the top of the gantry 51. The output shaft of the driving cylinder 53 is fixedly connected with the cutting tool 52.

[0031] Among them, when the carrier table 21 delivers the metal shell under the gantry 51, the driving cylinder 53 extends its output shaft, thereby pushing the cutting tool 52 to move downward under the gantry 51 to cut the waste material on the edge of the metal shell. After the cutting is completed, the driving cylinder 53 retracts its output shaft to lift the cutting tool 52.

[0032] The difference from the above embodiment is that a collection groove 6 is provided on the machine tool 1. The collection groove 6 is located under the gantry 51, and the collection groove 6 is in a slope shape on one side of the gantry 51.

[0033] Among them, after the cutting tool 52 cuts off the waste material, the cut waste material will fall into the collection groove 6 and roll down the slope to gather at the bottom of the collection groove 6, facilitating subsequent cleaning work.

[0034] The present invention also provides a processing method for switch production, which uses a metal shell cutting device. The specific steps are as follows: First, place the metal shell to be processed on the stage 21, and let the support frame 37 hold up the metal shell. After placing the metal shell, the stage 21 moves the metal shell towards the cutting component 5. During this process, the positioning component 4 presses the metal shell against the stage 21 through the positioning plate 46, thereby fixing the metal shell on the stage 21. After the stage 21 transports the metal shell to a suitable position under the gantry 51, the cutting knife 52 on the gantry 51 drops to cut off the waste material on the edge of the metal shell. After completing the cutting of one side of the metal shell, the stage 21 moves the metal shell away from the cutting component 5. During this process, the positioning plate 46 of the positioning component 4 rises to the top of the vertical frame 41. Subsequently, the steering rod 34 rotates to reverse the metal shell, so that the next side of the metal shell with waste material faces the cutting component 5. Then, the stage 21 drives the rotated metal shell to move towards the cutting component 5 again. Repeat the above steps until the waste materials on all four sides of the metal shell are cut off.

[0035] Working principle: When in use, the stage 21 in the initial state stops at one end of the guide rail 11 far from the cutting component 5. At this time, the connecting rod 45 is located at the top of the vertical frame 41, so that there is enough space between the positioning plate 46 and the stage 21 to place the metal shell to be processed on the stage 21. When the metal shell needs to be processed, first align the metal shell with the support frame 37 so that the metal shell covers the support frame 37. Among them, the size of the support frame 37 fits the internal size of the metal shell. When the metal shell covers the support frame 37, the bottom of the metal shell falls on the stage 21, and the top of the support frame 37 abuts against the top inside the metal shell, and the outer sides of the four sides of the support frame 37 are attached to the inner wall of the metal shell, thereby holding up the metal shell on the stage 21. At this time, one side of the metal shell faces the cutting component 5. After placing the metal shell, the stage 21 moves on the guide rail 11 towards the cutting component 5. During this process, the connecting rod 45 at the top of the vertical frame 41 moves downward, so that the positioning plate 46 on the connecting rod 45 falls on the top of the metal shell, thereby pressing the metal shell against the stage 21. The metal shell is fixed on the stage 21 through the cooperation of the support frame 37 and the positioning plate 46. When the stage 21 transports the metal shell under the gantry 51, the waste material on the side of the metal shell facing the gantry 51 at this time is directly below the cutting knife 52. At this time, the stage 21 stops moving, and the cutting knife 52 on the gantry 51 drops to cut off the waste material on the lower metal shell. After cutting off the waste material on this side of the metal shell, during this process, the metal shell on the stage 21 is supported by the support frame 37 inside and positioned by the positioning plate 46 outside, thereby preventing the metal shell from shifting or deforming when the cutting knife 52 cuts the waste material, thus ensuring the processing quality of the metal shell. The cutting knife 52 rises back to the top of the gantry 51, and at the same time, the stage 21 starts and moves away from the gantry 51 for the return journey; During the return process, the connecting rod 45 moves upward to the top of the vertical frame 41, causing the positioning plate 46 to disengage from the metal housing. Subsequently, after the positioning plate 46 rises, the feeding cylinder 31 extends its output shaft, enabling the push rod 33 to push the support frame 37 upward through the steering rod 34, thereby causing the limit block 35 on the steering rod 34 to disengage from the limit groove 321. The driving gear 36 enters the gear groove 23 and corresponds to the transmission rack, lifting the metal housing on the carrier table 21 and suspending it above the carrier table 21. As the carrier table 21 continues to move, the driving rack 39 passes by the side of the gear groove 23, engaging with the driving gear 36 in the gear groove 23 and driving the driving gear 36 to rotate. When the driving rack 39 passes through the gear groove 23, the driving rack 39 disengages from the driving gear 36. At this time, the driving gear 36 drives the steering rod 34 to rotate by ninety degrees, turning away the side of the metal housing that has been cut, and turning the other side to be cut towards the cutting assembly 5. After the metal housing is turned, the feeding cylinder 31 retracts its output shaft, causing the push rod 33 to drive the steering rod 34 to move downward, thereby placing the turned metal housing down. At the same time, the entire push rod 33 and the lower end of the steering rod 34 are again received into the socket 32, and the limit block 35 on the steering rod 34 is inserted into the limit groove 321 again, thus preventing the steering rod 34 from rotating. At the same time, the driving gear 36 disengages from the gear groove 23. By this time, the carrier table 21 has moved back to the initial position. Subsequently, the carrier table 21 starts to move in the reverse direction, transporting the metal housing to under the gantry 51 again. At the same time, the connecting rod 45 at the top of the vertical frame 41 moves downward again, pressing the positioning plate 46 against the top of the metal housing to fix it. After the carrier table 21 transports the metal housing to under the gantry 51 again, the cutting knife 52 drops again to cut off the waste material on the other side of the metal housing. When the waste material on this side of the metal housing is cut off, the carrier table 21 returns again and repeats the above steps until the waste material on all four sides of the metal housing is cut off. After the metal housing is processed, when the carrier table 21 returns to the initial position, the processed metal housing is taken off, and the next metal housing to be processed is placed on the carrier table 21 to repeat the above steps for processing.
