Detailed Implementation

[0029] 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.

[0030] Please see Figure 1-7 The present invention provides a technical solution:

[0031] Reference Figure 2 A tooling for wrapping the outer layer of copper bar with fireproof tape includes a base 1. The top of the base 1 is respectively provided with a copper bar fixing component 2, a copper bar template 30, a copper bar template fixing component 3, a tape 13 conveying mechanism, and a drive motor 5 for driving the copper bar fixing component 2 and the copper bar template fixing component 3 to rotate synchronously.

[0032] Reference Figure 2 , 4The base 1 has bases 6 on both sides of the top. The copper bar fixing component 2 is set on the side of the two bases 6 that are close to each other. The copper bar fixing component 2 includes a card seat 21 and a stop plate 22. The opposite end face of the two card seats 21 is provided with a card groove 7. The card groove 7 passes through the top of the card seat 21. The stop plate 22 is horizontally slidably set in the card groove 7. The inner wall of the side of the two sliding grooves 11 that are far apart from each other is provided with a spring 8, which is used to drive the stop plate 22 to press the copper bar 9 that is inserted between the two stop plates 22. When the copper bar 9 is placed between the two stop plates 22, the spring 8 will drive the two stop plates 22 to press the copper bar 9, thereby realizing the rapid pre-tightening of the copper bar 9.

[0033] Reference Figure 2 , 5 The conveyor belt 13 includes a moving table 4, a rotary motor, and a lead screw 10 fixed to the output end of the motor. A sliding groove 11 is provided on the base 1. A slider 12 is provided at the bottom of the moving table 4 and forms a sliding connection with the sliding groove 11. The lead screw 10 is rotatably mounted on the base 1. The lead screw 10 passes through the slider 12 and forms a threaded connection with the slider 12. The conveyor belt 13 is rotatably mounted on the top of the moving table 4.

[0034] Reference Figure 2 , 4 The copper bar fixing assembly 2 also includes a guide rod 23, a locking rod 24, and a nut 25 threadedly connected to the top of the locking rod 24. The guide rod 23 is fixed to the end face of the abutment plate 22 near the base 6. The card seat 21 is provided with a rod hole 14 for the guide rod 23 to slide. The top of the card seat 21 is provided with a sliding groove 15 for the locking rod 24 to slide horizontally. The part of the guide rod 23 located in the rod hole 14 is provided with a rod groove 16. The bottom end of the locking rod 24 is inserted into the rod groove 16 and is fixedly connected to a limiting plate 17. The inner wall of the rod groove 16 is provided with a limiting groove for the limiting plate 17 to slide. The spring 8 is sleeved on the guide rod 23. After the copper bar 9 is pressed against the abutment plates 22 on both sides, by rotating the nut 25, the mutual cooperation between the nut 25 and the limiting plate 17 will limit the continued sliding of the guide rod 23. In the rotation of the copper bar fixing assembly 2, the guide rod 23 will not slide horizontally, making the copper bar 9 more stable when wrapped with fireproof tape 13.

[0035] Reference Figure 3 The two end plates 22 are provided with a groove 18 for the copper bar 9 to be inserted on one side of their close proximity. The top of the end plate 22 is provided with a slope 19. When installing the copper bar 9, the copper bar 9 can be directly aligned with the top opening of the slot 7 and pressed down. The copper bar 9 slides down to the groove 18 by abutting against the slope 19, thus realizing the quick installation of the copper bar 9.

[0036] Reference Figure 2The top of the base plate is provided with second bases 20 on both sides. The copper bar template fixing component 3 is set on the side of the two second bases 20 that are close to each other. The copper bar template 30 is provided between the two copper bar template fixing components 3. The copper bar template 30 is made of rigid material and has the same shape as the copper bar 9. The copper bar template fixing component 3 has the same structure as the copper bar fixing component 2, and the way to fix the copper bar template 30 is the same as the way to fix the copper bar 9. The copper bar template 30 is made to replicate the shape of the copper bar 9 that needs to be wrapped with fireproof tape 13. The copper bar template 30 can be made of hard alloy material. When the moving platform 4 moves and drives the tape 13 to move, a specific moving trajectory can be formed according to the copper bar template 30.

[0037] Reference Figure 2 The copper bar fixing component 2 is rotatably connected to the base 6 via a rotating shaft 58. The copper bar template fixing component 3 is rotatably connected to the second base 20 via a second rotating shaft 32. One end of the first rotating shaft 31 extends to the outer end of the base 6 and is connected to the output shaft of the drive motor 5 via a belt 33. The other end of the second rotating shaft 32 extends to the outer end of the second base 20 and is connected to the output shaft of the drive motor 5 via a belt 33. The drive motor 5 can drive the copper bar template 30 and the copper bar 9 to rotate synchronously. In the initial state, the copper bar template 30 and the copper bar 9 are placed at the same angle, and the diameters of the first rotating shaft 31 and the second rotating shaft 32 are also the same.

[0038] Reference Figure 2 , 5 The movable platform 4 includes left and right sliding platforms 41 and front and rear sliding platforms 42. The left and right sliding platforms 41 slide left and right by rotating the lead screw 10. The top of the left and right sliding platforms 41 is provided with a T-slot 34. The bottom of the front and rear sliding platforms 42 is provided with a T-block 35 that is slidably connected to the T-slot 34. The front and rear sliding platforms 42 are slidably mounted on the left and right sliding platforms 41 towards the side closer to or away from the copper template 30 through the cooperation of the T-block 35 and the T-slot 34. One end of the left and right sliding platforms 41 is provided with a drive mechanism to drive the front and rear sliding platforms 42 to slide away from the copper template 30. The component includes a long rod 36 extending from one end of the front and rear sliding platforms 42 along the bottom end of the copper bar template 30. The end of the long rod 36 furthest from the front and rear sliding platforms 42 extends upwards with a first abutment 52 for abutting against the copper bar template 30. The first abutment 52 is located on the side of the copper bar template 30 furthest from the front and rear sliding platforms 42. Rotation of the copper bar template 30 will cause the first abutment 52 to slide back and forth, thereby causing the front and rear sliding platforms 42 to slide back and forth. When the copper bar 9 rotates to wrap the fireproof tape 13, because the copper bar 9 is furthest from the center (refer to...), Figure 7 Point a in the middle, Figure 7 The dotted line at point a represents the rotation trajectory of point a. The winding speed of the fireproof tape 13 is fastest at point V1, and the copper bar 9 is closest to the center (refer to...). Figure 7 Point b in the middle, Figure 7(The dotted line at point b represents the rotation trajectory of point b.) The winding speed V2 of the fireproof tape 13 is the slowest. When the tape 13 is started to be wound at point a, the copper bar template 30, corresponding to point a, will rotate and abut against the first abutment 52, causing the front and rear slides 42 to move a distance towards the copper bar 9. This causes the tape 13 to move a distance towards the copper bar 9, thus counteracting the acceleration when the tape 13 is wound at point a, and preventing a sudden increase in tension when the copper bar 9 is winding the fireproof tape 13 at point a, which could cause the copper bar 9 to fail to wrap the fireproof tape 13 properly. The instability that occurs at point 3: When the tape 13 is wrapped at point b, the copper bar template 30 will rotate to the wrapping point of the fireproof tape 13 at the corresponding point of point b. Under the action of the driving component, the first abutment 52 will remain against the copper bar template 30, causing the front and rear slides 42 to slide a distance away from the copper bar 9, so that the tape 13 moves a distance away from the copper bar 9, thus counteracting the deceleration of the copper bar 9 as it rotates from the wrapping pad at point a to the wrapping point at point b, and avoiding the shaking phenomenon caused by the sudden decrease in the force of the copper bar 9 wrapping the fireproof tape 13.

[0039] Reference Figure 5 The driving component includes a slide rod 53 and a second spring 37 sleeved on the slide rod 53. The left and right slide tables 41 have an extension plate 38 extending upward from the end away from the copper template 30. The end of the slide rod 53 away from the front and rear slide tables 42 passes through the extension plate 38 and is provided with a stop plate 39. The second spring 37 is disposed between the stop plate 39 and the extension plate 38 and is in a compressed state, so that the first stop rod 52 is always in a state of abutting against the copper template 30.

[0040] Reference Figure 5 The moving platform 4 also includes an upper and lower sliding platform 43. The top of the front and rear sliding platforms 42 is provided with a combination groove 51. The bottom of the upper and lower sliding platform 43 is provided with a combination rod 50 that slides up and down with the combination groove 51. The bottom end of the upper and lower sliding platform 43 extends downward with a second abutment rod 54 for abutting against the upper part of the copper bar template 30. The top of the front and rear sliding platforms 42 is provided with a third spring 55 for driving the upper and lower sliding platforms 43 to slide downward. It should be noted that the bottom of the combination rod 50 is a polygonal columnar structure and the top of the combination rod 50 is a columnar structure. The upper and lower sliding platform 43 will not rotate when it moves up and down through the combination rod 50. When the copper bar 9 rotates while wrapping the fireproof tape 13, the second abutment rod 54 continuously abuts against the copper bar template 30, so that the height position of the tape 13 when wrapped on the copper bar 9 remains unchanged, avoiding the instability of the copper bar 9 when wrapping the fireproof tape 13 due to the continuous up and down angle changes of the tape 13.

[0041] Reference Figure 6The upper and lower sliding platform 43 has a groove 56 at one end near the copper template 30. A bearing 57 is fixed in the middle of the tape 13. A rotating shaft 58 extends axially from the inner ring of the bearing 57. Bushings 59 are threaded on both sides of the groove 56. The bushings 59 are threaded onto the rotating shaft 58. It should be noted that the tape 13, bearing 57 and rotating shaft 58 are a combination. The tape 13 can be replaced through the threaded connection between the bushings 59 and the rotating shaft 58.

[0042] Reference Figure 6 The groove 56 is provided with a disc groove 60, and a base plate 61 is rotatably provided in the disc groove 60. Side rods 62 are symmetrically provided on both sides of the base plate 61. The inner walls of the two sides of the disc groove 60 are provided with swing grooves 63 through the upper and lower sliding tables 43 for the side rods 62 to swing. The middle of the base plate 61 is provided with a rotating area 64 for the tape 13 to rotate. The bushing 59 is threaded to the inner walls of the two sides of the rotating area 64. The lead screw 10 drives the moving table 4 to move so that when the tape 13 wraps around the copper bar 9 during the movement, it can achieve a certain angle of rotation through the cooperation of the side rods 62 and the swing grooves 63. This avoids the instability caused by the lateral tension generated when the tape 13 moves through the moving table 4 and wraps around the copper bar 9.

[0043] Example 1:

[0044] A tooling for wrapping fireproof tape on the outer layer of a copper bar 9 is described. When wrapping the copper bar 9 with fireproof tape 13, the two ends of the copper bar 9 are first aligned with the slots 7 on the top of the mounting base 21, and the copper bar 9 is pressed down so that the copper bar 9 abuts against the inclined surfaces 19 on the abutment plates 22 in the slots 7 on both sides, and the abutment plates 22 slide away from each other. The copper bar 9 is pressed down until the two ends of the copper bar 9 are respectively inserted into the grooves 18 of the abutment plates 22 on both sides. Under the action of the spring 8, the abutment plates 22 on both sides are driven to press the copper bar 9 tightly. By rotating the nut 25 on the locking rod 24, the nut 25 and the limiting plate 17 will press the guide rod 23 to prevent the guide rod 23 from continuing to slide. When the copper bar 9 is wrapped with tape 13, the copper bar 9 will not move left or right.

[0045] Pull out the end of the tape 13 and attach it to one end of the copper bar 9. At the same time, start the drive motor 5 and the rotary motor. The drive motor 5 drives the card holder 21 to rotate, and the rotary motor drives the lead screw 10 to rotate, thereby moving the moving table 4 horizontally, so that the tape 13 is evenly wrapped around the surface of the copper bar 9.

[0046] Example 2:

[0047] This embodiment is based on the first embodiment. A copper bar template 30 of the same shape is made to replicate the shape of the copper bar 9 to be wound as needed. The copper bar template 30 is fixed on the copper bar template fixing component 3. The way the copper bar template 30 is fixed on the copper bar template fixing component 3 is the same as the way the copper bar 9 is fixed on the copper bar fixing component 2.

[0048] The output of the drive motor 5 is connected to the first rotating shaft 31 and the second rotating shaft 32 via belts 33, enabling the copper bar template 30 and the copper bar 9 to rotate synchronously. The front and rear slides 42 are equipped with a first abutment 52 that continuously abuts against the end of the copper bar template 30 away from the front and rear slides 42. When the copper bar 9 wraps the tape 13, the wrapping pad on top of the copper bar 9, used to pull the tape 13, moves back and forth. Through the synchronous rotation of the copper bar template 30 and the copper bar 9, the copper bar template 30 and the second rotating shaft 32 rotate synchronously. The continuous contact of the abutment rod 52 causes the tape 13 to move back and forth along the winding pad of the copper bar template 30, keeping the length of the tape 13 extending to the copper bar 9 relatively constant. This avoids the vibration caused by the sudden increase in tension due to the tape 13 being stretched (from winding point b to winding point a), and also avoids the vibration caused by the sudden decrease in tension due to the tape 13 being stretched (from winding point a to winding point b).

[0049] Example 3:

[0050] This embodiment is based on embodiment one or embodiment two. When the copper bar 9 is wrapping the tape 13, the second abutment 54 at the bottom of the upper and lower sliding platform 43 continuously abuts against the copper bar template 30 under the tension of the third spring 55. As the wrapping point a and wrapping point b are located at the top wrapping point and change cyclically, the top wrapping point of the copper bar 9 rises or falls. Under the continuous abutment action of the second abutment 54 and the copper bar template 30, the upper and lower sliding platform 43 will drive the tape 13 to move up and down, so that the tape 13 and the top wrapping point of the copper bar 9 always maintain the same horizontal height, and avoid the continuous change of angle of the part of the tape 13 extending to the top of the copper bar 9, which would cause the force on the copper bar 9 to change continuously.

[0051] Example 4:

[0052] This embodiment is based on embodiment one, two, or three. When the lead screw 10 rotates and drives the left and right slides 41 to move at a constant speed, the tape 13 moves horizontally and wraps around the copper bar 9, which will cause the tape 13 to receive axial tension. By setting the base plate 61, the base plate 61 can rotate at a certain angle in the swing groove 63 through the side rod 62, so that the tape 13 tilts at a certain angle when it moves, making the tape 13 more stable when it moves horizontally and wraps around the copper bar 9.
