Description

Technical Field

[0001] This utility model relates to the field of flaring device technology, and in particular to an air conditioning coil flaring device. Background Technology

[0002] An air conditioning coil flaring device is a special tool used for connecting copper pipes in air conditioning systems. It mainly uses mechanical force to expand the end of the copper pipe into a specific shape, so that the two pipes can be tightly connected and form a sealed connection. With the help of fittings, it can achieve a reliable connection of the pipeline.

[0003] When using an air conditioning coil flaring tool to flare the coil, the coil needs to be inserted into a die of a specific size in the die plate. Then, a threaded push rod is used to press the inner wall of the coil. One end of the threaded push rod is tapered. When pressing the inner wall of the coil, the coil will gradually expand until the outer surface of the coil is completely in contact with the inner wall of the die. During this process, the coil can easily detach from the die plate, which makes it difficult to perform the normal flaring process. Utility Model Content

[0004] This utility model proposes an air conditioning coil flaring device to solve the problem that during the flaring process, the pipe can easily detach from the mold plate, which makes it difficult to carry out the normal flaring process of the pipe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an air conditioning coil flaring device, comprising a die plate, characterized in that: a screw hole block is provided on one side of the outer surface of the die plate, a limiting plate is symmetrically installed on one side of the screw hole block, two limiting plates are slidably installed on the outer surface of the die plate, a threaded pin is threadedly inserted into the inner wall of one of the limiting plates, a threaded push rod is threadedly connected to the inner wall of the screw hole block, one end of the threaded push rod is tapered, a handle is fixedly installed at the other end of the threaded push rod, and a fixing device is provided at the bottom of the two limiting plates, the fixing device clamping and fixing the air conditioning coil by setting two clamping plates.

[0006] The effect achieved by the above components is as follows: by setting two clamping plates and adjusting the two clamping plates respectively, the two clamping plates can be moved towards the air conditioning coil until the air conditioning coil is completely clamped. Then the two clamping plates can fix the air conditioning coil and the die plate, which helps to prevent the coil from falling off the die plate, and thus facilitates the normal processing of the coil flaring.

[0007] Preferably, the fixing device includes two side plates, which are fixedly installed at the bottom of the limiting plate. The bottom of the two side plates is fixedly installed with the same auxiliary ring. Two round rods are slidably installed on the inner wall of the side plates, and one end of the two round rods is fixedly installed with the same clamping plate.

[0008] The effect achieved by the above components is as follows: after inserting the pipe into the inner wall of the corresponding mold opening in the mold plate, push the two clamping plates respectively, so that the two clamping plates move towards the pipe until the two clamping plates completely clamp the pipe. This can provide auxiliary fixation between the pipe and the mold plate, which helps to prevent the pipe from easily detaching from the mold plate during the process of flaring the pipe.

[0009] Preferably, an extension plate is fixedly installed on one side of the clamping plate, and a wire is fixedly installed on the side of the two extension plates that are close to each other. A wire wheel is rotatably installed at the bottom of the auxiliary ring, and one end of each of the two wires is fixedly installed on the outer surface of the wire wheel.

[0010] The effect achieved by the above components is as follows: when the spool is rotated, the spool will wind both filaments around the outer surface of the spool. At the same time, the filaments will drive the clamps connected to the extension plate to move in opposite directions until the two clamps completely clamp the pipe. This makes it easier to adjust the two clamps simultaneously and synchronously through the spool, simplifying the operation steps.

[0011] Preferably, a spring is sleeved on the outer surface of the round rod, one end of the spring is fixedly installed on one side of the side plate, and the other ends of the two round rods and the two springs are fixedly installed on the same connecting plate.

[0012] The effect achieved by the above components is as follows: by setting springs, when the two clamping plates move under the action of the line body, the clamping plates will drive the connecting plate connected to the round rod to squeeze the spring. Then, the fixing of the clamping plates is removed, the spring will reset, and drive the two clamping plates to move away from each other, thereby facilitating the quick installation and disassembly of the pipe.

[0013] Preferably, a handwheel is fixedly installed at the bottom of the reel, the handwheel is rotatably mounted on the top of the auxiliary ring, and the outer surface of the handwheel is provided with protrusions.

[0014] The effect achieved by the above components is as follows: by setting a handwheel, turning the handwheel can drive the thread wheel to rotate. At the same time, the outer surface of the handwheel is provided with protrusions, which can effectively increase the friction of the outer surface of the handwheel and have an anti-slip effect when turning the handwheel.

[0015] Preferably, a bolt is threaded into the top of the handwheel, and the bolt is located on the top of the auxiliary ring.

[0016] The effect achieved by the above components is as follows: by rotating the bolt, the bolt passes through the inner wall of the handwheel until one end of the bolt abuts against the top of the auxiliary ring, the bolt can fix the spool, which helps to prevent the spool from loosening and causing the two clamps to loosen their fixation to the air conditioning coil.

[0017] Preferably, an auxiliary plate is fixedly installed on the side of each of the two clamping plates that are close to each other, and the horizontal cross-section of the two auxiliary plates is "V" shaped.

[0018] The effect achieved by the above components is as follows: by setting a V-shaped auxiliary plate to replace the outer surface of one row of pipes on one side of the clamping plate, the contact area between the two clamping plates and the pipes can be increased, thereby making the two clamping plates more stable in fixing the pipes.

[0019] Preferably, a rubber plate is fixedly installed on the side of each of the two auxiliary plates that are close to each other.

[0020] The effect achieved by the above components is that by setting the rubber plate, the friction between the auxiliary plate and the pipe can be increased, thereby further improving the stability of the two clamps in fixing the pipe.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, two clamping plates are set up and adjusted to move towards the air conditioning coil until the air conditioning coil is completely clamped. This fixes the air conditioning coil and the die plate, which helps to prevent the coil from detaching from the die plate and facilitates the normal processing of the coil flaring.

Detailed Implementation

[0024] Example 1, referring to Figures 1-3As shown, this embodiment discloses an air conditioning coil flaring device, including a die plate 1. A screw hole block 2 is provided on one side of the outer surface of the die plate 1. Limiting plates 3 are symmetrically installed on one side of the screw hole block 2. The two limiting plates 3 are slidably installed on the outer surface of the die plate 1. A threaded pin 4 is threadedly inserted into the inner wall of one of the limiting plates 3. A threaded push rod 5 is threadedly connected to the inner wall of the screw hole block 2. One end of the threaded push rod 5 is tapered, and a handle 6 is fixedly installed at the other end of the threaded push rod 5. A fixing device 7 is provided at the bottom of the two limiting plates 3. The fixing device 7 clamps and fixes the air conditioning coil by setting two clamping plates 72. By setting the two clamping plates 72, the two clamping plates 72 are adjusted to move towards the air conditioning coil until the two clamping plates 72 completely clamp the air conditioning coil. The two clamping plates 72 can fix the air conditioning coil and the die plate 1, which helps to prevent the coil from falling off the die plate 1, and thus facilitates the normal processing of the coil flaring.

[0025] Reference Figure 2 and Figure 5 As shown, the fixing device 7 includes two side plates 71, which are fixedly installed at the bottom of the limiting plate 3. The bottom of the two side plates 71 is fixedly installed with the same auxiliary ring 77. Two round rods 710 are slidably installed on the inner wall of the side plates 71. One end of the two round rods 710 is fixedly installed with the same clamping plate 72. After the tube is inserted into the inner wall of the corresponding mold opening in the mold plate, the two clamping plates 72 are pushed respectively, so that the two clamping plates 72 move towards the tube until the two clamping plates 72 completely clamp the tube. This can provide auxiliary fixing between the tube and the mold plate 1, which helps to prevent the tube from easily detaching during the flaring process. The die plate 1 and clamping plate 72 are fixedly mounted on one side with an extension plate 74. Two wire bodies 75 are fixedly mounted on the side of the two extension plates 74 that are close to each other. A wire wheel 76 is rotatably mounted on the bottom of the auxiliary ring 77. One end of each wire body 75 is fixedly mounted on the outer surface of the wire wheel 76. When the wire wheel 76 is rotated, the wire wheel 76 will wind the two wire bodies 75 around the outer surface of the wire wheel 76. At the same time, the wire bodies 75 will drive the clamping plate 72 connected to the extension plate 74 to move towards each other until the two clamping plates 72 completely clamp the pipe. This makes it easier to adjust the two clamping plates 72 simultaneously and synchronously through the wire wheel 76, simplifying the operation steps.

[0026] Reference Figure 2 and Figure 3As shown, a spring 78 is sleeved on the outer surface of the round rod 710. One end of the spring 78 is fixedly installed on one side of the side plate 71. The other ends of the two round rods 710 and the two springs 78 are fixedly installed with the same connecting plate 79. By setting the spring 78, when the two clamping plates 72 move under the action of the line body 75, the clamping plates 72 will drive the connecting plate 79 connected to the round rod 710 to squeeze the spring 78. Then, the fixation of the clamping plates 72 is removed, the spring 78 will reset, and drive the two clamping plates 72 to move away from each other, thereby facilitating the quick installation and disassembly of the pipe.

[0027] Reference Figure 4 and Figure 5 As shown, a handwheel 711 is fixedly installed at the bottom of the spool 76. The handwheel 711 is rotatably mounted on the top of the auxiliary ring 77. The outer surface of the handwheel 711 has protrusions. By setting the handwheel 711, rotating the handwheel 711 can drive the spool 76 to rotate. At the same time, the protrusions on the outer surface of the handwheel 711 can effectively increase the friction of the outer surface of the handwheel 711, which has an anti-slip effect when rotating the handwheel 711. A bolt 712 is threaded into the top of the handwheel 711. The bolt 712 is located on the top of the auxiliary ring 77. Rotating the bolt 712 allows the bolt 712 to pass through the inner wall of the handwheel 711 until one end of the bolt 712 abuts against the top of the auxiliary ring 77. The bolt 712 can then fix the spool 76, which helps to prevent the spool 76 from loosening and causing the two clamps 72 to loosen their fixation to the air conditioning coil.

[0028] Reference Figure 2 , Figure 3 and Figure 6 As shown, auxiliary plates 73 are fixedly installed on the side of the two clamping plates 72 that are close to each other. The horizontal cross-section of the two auxiliary plates 73 is "V" shaped. By setting the V-shaped auxiliary plates 73, the outer surface of one row of pipes on one side of the clamping plate 72 is replaced to abut against it, which can increase the contact area between the two clamping plates 72 and the pipes, and thus make the fixation of the two clamping plates 72 on the pipes more stable. Rubber plates 713 are fixedly installed on the side of the two auxiliary plates 73 that are close to each other. By setting the rubber plates 713, the friction between the auxiliary plates 73 and the pipes can be increased, thereby further improving the stability of the fixation of the two clamping plates 72 on the pipes.

[0029] Working principle: After inserting the tube into the inner wall of the corresponding die opening in the die plate, turn the handwheel 711 to drive the thread wheel 76 to rotate. The thread wheel 76 will wind both threads 75 around its outer surface. At the same time, the threads 75 will drive the clamping plates 72 connected to the extension plate 74 to move in opposite directions. The clamping plates 72 will drive the auxiliary plates 73 to move synchronously until the rubber plates 713 on one side of the two auxiliary plates 73 completely clamp the tube. Then turn the bolt 712 so that the bolt 712 passes through the inner wall of the handwheel 711 until one end of the bolt 712 abuts against the top of the auxiliary ring 77. Then the bolt 712 can engage the thread wheel 76. Fixing the coil helps prevent the reel 76 from loosening, which could cause the two clamps 72 to loosen their fixation on the air conditioning coil. This also helps to provide auxiliary fixation between the coil and the die plate 1, preventing the coil from easily detaching from the die plate 1 during the flaring process. When the two clamps 72 move under the action of the coil body 75, the clamps 72 will drive the connecting plate 79 connected to the round rod 710 to compress the spring 78. Removing the fixation on the clamps 72 will cause the spring 78 to reset and move the two clamps 72 away from each other, thus facilitating the quick installation and removal of the coil.
