Description

Technical Field

[0001] This utility model relates to the field of copper elbow bending technology, and in particular to a quick-fixing and bending device for copper elbows. Background Technology

[0002] Copper elbows are important accessories in air conditioning systems used to connect pipes and change the direction of pipes. During the processing of copper elbows, bending devices are usually required to bend them.

[0003] Existing bending devices typically bend copper elbows by directly engaging a deflection arm and a bending block. However, in practice, the bending block usually does not fix the end of the copper elbow. During the deflection of the copper elbow by the deflection arm, the copper elbow and the bending block will shift, making it impossible to stably bend the copper elbow. Therefore, we propose a quick-fixing bending device for copper elbows. Utility Model Content

[0044] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0045] Example:

[0046] like Figures 1-6 As shown, 1. A quick-fixing and bending device for copper elbows, comprising:

[0047] Mounting base 1, with a support column at its bottom end, and a worm gear is movably installed inside it;

[0048] The output motor 2 is bolted to one side of the mounting base 1, and its output end is equipped with a worm gear;

[0049] Rotating shaft 3 is fixedly installed at the top center of the worm gear inside the mounting base 1;

[0050] The first fixed slot 4 is located at the top center of the rotating shaft 3;

[0051] The deflection mechanism 5 is movably inserted into the inside of the first fixed slot 4 and is located on top of the mounting base 1;

[0052] The fixed clamping mechanism 6 is fixedly mounted on one side of the deflection and bending mechanism 5;

[0053] The second fixing slot 7 is fixedly opened at the top edge of the mounting base 1;

[0054] The mounting groove 8 is fixedly opened on the outside of the mounting base 1 and is located at the end of the second fixing slot 7;

[0055] The connecting limiting mechanism 9 is movably inserted into the inner side of the second fixed slot 7 and the fixed mounting groove 8, and is connected and fixed to the mounting base 1 by bolts;

[0056] The copper tube body 10 is detachably disposed inside the fixed clamping mechanism 6 and is in contact with the inner edge of the deflection bending mechanism 5 and the output end surface of the connecting limiting mechanism 9.

[0057] The working principle of the above technical solution is as follows:

[0058] During use, the copper tube body 10 can be clamped and fixed by the fixed clamping mechanism 6, while the connecting limiting mechanism 9 can restrict the copper tube body 10. Then, the output motor 2 can drive the worm and worm wheel, which in turn drive the rotating shaft 3, the deflection bending mechanism 5 and the fixed clamping mechanism 6, so that the copper tube body 10 can be bent under the action of the deflection bending mechanism 5. At the same time, the internal components of the deflection bending mechanism 5, the fixed clamping mechanism 6 and the connecting limiting mechanism 9 can be quickly disassembled and replaced according to the size of the copper tube body 10. It can bend copper tube bodies 10 of different sizes. The structure is simple and the operation is convenient and quick.

[0059] In another embodiment, such as Figure 3 As shown, the deflection mechanism 5 includes a first connecting block 51 inserted into the inner side of the first fixed slot 4, a deflection block 52 fixedly connected to the top of the first connecting block 51, and a first fixed groove 53 provided on the outer edge of the deflection block 52.

[0060] This facilitates the insertion of the first connecting plug 51 into the inner side of the first fixing slot 4, thereby enabling the overall installation of the deflection block 52 and the fixing clamping mechanism 6, making operation convenient.

[0061] In another embodiment, such as Figure 4 As shown, the fixed clamping mechanism 6 includes a fixed connecting block 61 fixedly disposed on the outside of the deflection block 52. The fixed connecting block 61 has a U-shaped through groove 62 inside. A threaded mounting sleeve 63 is fixedly connected to the middle of one end of the fixed connecting block 61. A threaded rod 64 is movably connected to the inner side of the threaded mounting sleeve 63 by a thread. The outer surface of the threaded rod 64 and the inner end of the fixed connecting block 61 slide against each other. A rotating end block 65 is fixedly connected to one end of the threaded rod 64. A connecting push-pull plate 66 is fixedly connected to the other end of the threaded rod 64. A movable sleeve block 67 is movably sleeved on the outer surface of the connecting push-pull plate 66. A connecting pressing block 68 is fixedly connected to one side of the movable sleeve block 67. A second fixed groove 69 is provided on one side of the connecting pressing block 68.

[0062] When one end of the copper tube body 10 is inside the U-shaped through groove 62, the rotating end block 65 can be rotated, causing the threaded rod 64 and the connecting push-pull plate 66 to rotate. This allows the threaded rod 64 to rotate and move inside the threaded mounting sleeve 63 and the end of the fixed connecting block 61, thus moving the connecting push-pull plate 66. Simultaneously, when the connecting push-pull plate 66 moves, it can drive the movable sleeve block 67 and the connecting pressing block 68, allowing the connecting pressing block 68 and the fixed connecting block 61 to clamp and fix the copper tube body 10 under the action of the second fixing groove 69 and the U-shaped through groove 62, respectively, making operation convenient.

[0063] In another embodiment, such as Figure 4 As shown, the inner side of the U-shaped through groove 62 and the inner side of the second fixing groove 69 are both in contact with the outer side of the end surface of the copper tube body 10.

[0064] The connecting compression block 68 and the fixing connecting block 61 can stably clamp the end of the copper tube body 10 under the action of the second fixing groove 69 and the U-shaped through groove 62, thereby fixing the copper tube body 10.

[0065] In another embodiment, such as Figure 5As shown, the connecting limiting mechanism 9 includes a connecting mounting block 91. Second connecting inserts 92 are fixedly connected to the middle of both sides of the connecting mounting block 91. Connecting supports 93 are fixedly connected to both sides of one end of the connecting mounting block 91. A fixed cavity 94 is formed inside the connecting mounting block 91. A threaded adjusting rod 95 is movably connected inside the connecting mounting block 91. A rotating end plate 96 is fixedly connected to one end of the threaded adjusting rod 95. A movable mounting base 97 is threadedly connected to the outer surface of the threaded adjusting rod 95. The top of the movable mounting base 97 is fixedly... A connecting limit component 98 is fixedly connected, and a movable limit block 99 is movably engaged on the inner side of the connecting limit component 98. A fixed insertion hole 910 is provided on one side of the movable limit block 99, and a connecting handle 911 is fixedly connected to the top of the movable limit block 99. A third fixed groove 912 is provided on the other side of the movable limit block 99. Two fixed limit collars 913 are fixedly sleeved on the outer surface of the threaded adjustment rod 95. The sides of the two fixed limit collars 913 that are close to each other slide against the inner and outer sides of one end of the connecting mounting block 91.

[0066] To facilitate the restriction of copper tube bodies 10 of different sizes, the connecting limiting component 98 is operated first, and the movable limiting block 99 is replaced. The movable limiting block 99 that matches the third fixing groove 912 is then replaced with the one that matches the copper tube body 10. Then, the rotating end plate 96 is rotated, causing the movable mounting base block 97 to move on the outer side of the threaded adjusting rod 95 and the inner side of the connecting mounting block 91. This causes the connecting limiting component 98 and the movable limiting block 99 to move, so that the movable limiting block 99 fits against the surface of the copper tube body 10 under the action of the third fixing groove 912, thereby restricting the copper tube body 10. The operation is convenient.

[0067] In another embodiment, such as Figure 6 As shown, the connecting limiting assembly 98 includes a fixed limiting frame 981. A connecting sleeve 982 is fixedly connected to one side of the fixed limiting frame 981. A movable limiting rod 983 is movably connected inside the connecting sleeve 982 and the fixed limiting frame 981. A force-bearing collar 984 is fixedly sleeved on the outer surface of the movable limiting rod 983. A force-bearing spring 985 is fixedly connected to the side of the force-bearing collar 984 away from the fixed limiting frame 981. A connecting pull plate 986 is fixedly connected to the end of the movable limiting rod 983 away from the fixed limiting frame 981.

[0068] The connecting pull plate 986 is easy to pull, which drives the movable limit plug rod 983 and the force-bearing collar 984 to move, compressing the force-bearing spring 985, so that the end of the movable limit plug rod 983 can be pulled out from the inside of the fixed plug hole 910, thereby quickly disassembling the movable limit block 99, which is convenient to operate.

[0069] In another embodiment, such as Figure 5 and Figure 6 As shown, the outer surface of the end of the movable limiting rod 983 near the fixed limiting frame 981 slides and fits against the inner surface of the fixed insertion hole 910.

[0070] The end of the movable limiting rod 983 can be stably inserted into the inside of the fixed socket 910 for connection and positioning.

[0071] The working principle of this utility model is as follows: First, the deflection bending mechanism 5, the fixed clamping mechanism 6, and the movable limiting block 99 are selected to match the size of the copper tube body 10 to be bent. Then, the first connecting plug 51 is inserted into the inner side of the first fixed slot 4, and the deflection bending mechanism 5 and the fixed clamping mechanism 6 are installed as a whole. Next, the connecting pull plate 986 is pulled, causing the movable limiting plug 983 and the force-bearing collar 984 to move, compressing the force spring 985, so that the end of the movable limiting plug 983 can move towards the connecting collar. The inner side of the cylinder 982 contracts, and then the movable limiting block 99 is inserted into the inner side of the fixed limiting frame 981. The connecting pull plate 986 is released, so that the force-bearing collar 984, under the action of the force-bearing spring 985, drives the movable limiting rod 983 to move and reset, so that the end of the movable limiting rod 983 is inserted into the inner side of the fixed insertion hole 910, limiting and fixing the position of the movable limiting block 99. Then, the end of the copper tube body 10 is inserted into the inner side of the U-shaped through groove 62, and the rotating end block 65 is rotated, driving the threaded rod 64 and the connecting push-pull plate 66 to move. Rotation allows the threaded rod 64 to rotate and move within the threaded mounting sleeve 63 and the inner end of the fixed connecting block 61, driving the connecting push-pull plate 66 to move. Simultaneously, as the connecting push-pull plate 66 moves, it drives the movable sleeve block 67 and the connecting pressing block 68, allowing the connecting pressing block 68 and the fixed connecting block 61 to clamp and fix the copper tube body 10 under the action of the second fixing groove 69 and the U-shaped through groove 62, respectively. Then, the rotating end plate 96 rotates, causing the movable mounting base block 97 to move on the outer surface of the threaded adjusting rod 95. The motor moves along the inner side of the connecting mounting block 91, causing the connecting limiting component 98 and the movable limiting block 99 to move. Under the action of the third fixing groove 912, the movable limiting block 99 fits against the surface of the copper tube body 10, thereby restricting the copper tube body 10. Finally, the output motor 2 drives the worm gear and worm wheel, causing the first connecting plug 51 and the deflection block 52 to deflect. Under the action of the first fixing groove 53, and in conjunction with the restriction of the movable limiting block 99, the copper tube body 10 can be bent. The overall structure is simple and the operation is convenient and quick.

[0072] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
