Description

According to the working principle, it can be divided into compression refrigeration equipment, absorption refrigeration equipment, steam jet refrigeration equipment, heat pump refrigeration equipment and electric heating refrigeration equipment. The heat of the object and its surroundings is removed through the working cycle of the equipment to create and maintain a certain low temperature state. Among them, the heat exchanger is one of the important components. In the manufacturing process of the heat exchanger, the straight tube or large U-tube needs to be welded and connected with the short U-tube, and the U-tube needs to be bent and formed using the corresponding equipment.

The first conveying device is used to convey the tube material, and the cutting device is arranged downstream of the first conveying device. The cutting device is used to cut the tube material to form a tube fitting of a predetermined length. The tube end processing device is arranged downstream of the cutting device along the conveying direction; the tube end processing device has a tube mouth processing portion for expanding and / or deburring the tube mouth of the tube fitting, and the bending device is used to bend the tube fitting to form a U-shaped tube. The second conveying device is arranged below the bending device, and the second conveying device is used to convey the U-shaped tube. The material return device is used to push the U-shaped tube from the bending device to the second conveying device.

[0004] The above technical solution realizes the automatic processing and forming of the U-shaped tube, but there are still many shortcomings.

[0043] See also Figure 1-12 The present invention provides a technical solution: an automatic production system for refrigeration and air conditioning components and a working method thereof, comprising a workbench 1, a feeding belt 7, a feeding channel 8, a bending part and a push rod 4,

[0044] A plurality of groove wheels 801 are arranged in the feeding channel 8, and the groove wheels 801 are used to transport the straight pipe body 9 to the bending part;

[0045] The bending part includes a pair of bending moving wheels and a bending fixed wheel 103, both of which are provided with grooves adapted to the straight tube body 9, and the straight tube body 9 moves between the pair of bending moving wheels and the bending fixed wheel 103, and the pair of bending moving wheels make circular motion with the bending fixed wheel 103 as the axis and the movement directions of the pair of bending moving wheels are opposite, so as to bend the straight tube body 9 into a U-shaped tube 6;

[0046] A discharge chute 5 is provided on one side of the workbench 1 , and a pair of push rods 4 are provided. The push rods 4 are used to push the formed U-shaped tube 6 out of the bending portion to the discharge chute 5 . The feeding belt 7 is arranged on the lower side of the discharge chute 5 .

[0047] The straight tube body 9 to be processed is transported by a plurality of groove wheels 801, and the straight tube body 9 moves along the feeding channel 8 to the inside of the bending part. Specifically, the straight tube body 9 moves between a pair of bending moving wheels and a bending fixed wheel 103, and the midpoint of the straight tube body 9 moves to the center of the bending fixed wheel 103. Since the surfaces of the bending moving wheels and the bending fixed wheel 103 are both provided with grooves adapted to the straight tube body 9, the pair of bending moving wheels and the bending fixed wheel 103 are respectively attached to the two sides of the straight tube body 9, and then the pair of bending moving wheels make a circular motion with the bending fixed wheel 103 as the axis and the pair of bending moving wheels move in the opposite direction, so that the pair of bending moving wheels move along As the bending fixed wheel 103 moves in opposite directions in the circumference, a pair of bending moving wheels push the two ends of the straight tube body 9 respectively and drive it to bend relatively, so that the straight tube body 9 is bent with the bending fixed wheel 103 as the center to form a U-shaped tube 6; then the pushing rod 4 pushes the formed U-shaped tube 6 to separate it from between the bending moving wheel and the bending fixed wheel 103 and fall into the unloading chute 5; the U-shaped tube 6 falls along the unloading chute 5 to the feeding belt 7, and the feeding belt 7 feeds the U-shaped tube 6 to the next process to complete the bending and forming work. The subsequent straight tube body 9 is processed according to the above process, thereby realizing automatic and continuous bending and forming operations with high work efficiency.

[0048] The bending moving wheel includes a moving wheel 101 and a moving wheel 102. One side of the moving wheel 102 is rotatably connected to a connecting rod 104. The connecting rod 104 penetrates and is fixedly connected to a turntable 105. One side of the moving wheel 101 is rotatably connected to a connecting rod 109. The turntable 105 penetrates and is provided with an arc groove 106. The connecting rod 109 passes through the arc groove 106. One end of the connecting rod 109 penetrates and is fixedly connected to a turntable 107. The turntable 107 is rotatably connected to the turntable 105. The turntable 107 penetrates and is provided with an arc groove 108. The connecting rod 104 passes through the arc groove 108.

[0049] Preferably, when it is necessary to drive the moving wheel 101 and the moving wheel 2 102 to move relative to each other, the connecting rod 2 104 is displaced in an annular manner to drive the turntable 2 105 to rotate around the axis of the bending fixed wheel 103. Similarly, the connecting rod 109 drives the turntable 107 to rotate, that is, the turntable 107 and the turntable 2 105 rotate in opposite directions, thereby driving the moving wheel 101 and the moving wheel 2 102 to move relative to each other and perform the bending work. The arc groove 2 106 and the arc groove 108 are correspondingly provided to respectively adapt to the displacement of the connecting rod 109 and the connecting rod 2 104. The turntable 107 and the turntable 2 105 are in contact with each other and are rotatably connected, thereby further improving the stability of the moving wheel 101 and the moving wheel 2 102 in bending the straight tube body 9 and ensuring the forming accuracy.

[0050] The lower end of the turntable 107 is rotatably connected to a fixed disk 110, and the fixed disk 110 is fixed inside the workbench 1. The fixed disk 110 is penetrated by an arc groove 3 112, and the connecting rod 109 and the connecting rod 2 104 both pass through the arc groove 3 112. A limiting square opening 2 is provided at the lower end of the workbench 1, and the upper end of the limiting square opening 2 is connected to the fixed disk 110. A moving rod 201 is slidably fitted in the limiting square opening 2, and a pair of limiting blocks 202 are slidably fitted on one side of the moving rod 201. The connecting rod 109 and the connecting rod 2 104 respectively pass through a pair of limiting blocks 202 and are fixedly connected thereto.

[0051] Preferably, when it is necessary to drive turntable 1 107 and turntable 2 105 to rotate relative to each other, the moving rod 201 is displaced in the limiting square opening 2, thereby driving a pair of limiting blocks 202 to displace, and the limiting blocks 202 slide along the moving rod 201 to adapt to the two ends, thereby driving connecting rod 1 109 and connecting rod 2 104 to move in a circle along arc groove 3 112, so that the moving wheel 1 101 and the moving wheel 2 102 can be relatively displaced to perform bending and forming work.

[0052] A center column 111 passes through and is fixedly connected to the center end of the fixed disk 110. The center column 111 passes through the turntable 1 107 and the turntable 2 105 respectively and is rotatably connected thereto. A U-shaped groove is provided at one end of the center column 111. A center rod 113 is provided in the U-shaped groove. A plurality of guide telescopic rods are provided between the center rod 113 and the U-shaped groove. The U-shaped groove is arranged away from the arc groove 3 112. One end of the center rod 113 is rotatably connected to the bending fixed wheel 103, and the other end of the center rod 113 is fixedly connected to the moving block 205.

[0053] Preferably, since both the bending fixed wheel 103 and the bending moving wheel are in close contact with the straight tube body 9 during the bending forming, the forming accuracy of the U-shaped tube 6 can be guaranteed. On the contrary, if there is a large gap between the bending fixed wheel 103 and the bending moving wheel and the straight tube body 9, the U-shaped tube 6 after forming is not bent in place, resulting in poor accuracy. Therefore, it is necessary to ensure that the distance between the bending fixed wheel 103 and a single bending moving wheel just accommodates the diameter of the straight tube body 9. However, the bending moving wheels are divided into moving wheel 101 and moving wheel 2 102. When the two are in contact, the shortest distance between the moving wheel 101 and the moving wheel 2 102 and the bending fixed wheel 103 is smaller than the diameter of the straight tube body 9 (such as Fig.12As shown), that is, the straight tube body 9 cannot enter between the bending fixed wheel 103 and the two moving wheels, so a center column 111 and a center rod 113 are provided, and a U-shaped groove is provided on one side of the center column 111, and the center rod 113 can move in the U-shaped groove and a guide telescopic rod is provided between the two to guide the displacement of the center rod 113. When the straight tube body 9 is loaded, the moving block 205 drives the center rod 113, so that the bending fixed wheel 103 is away from the axis of the center column 111, that is, away from the bending center, until the two moving wheels The distance between the bending fixed wheel 103 and the straight tube body 9 can accommodate the straight tube body 9, so that the straight tube body 9 can enter therein, thereby completing the loading work. Then when the bending work needs to start, the center rod 113 drives the bending fixed wheel 103 to reset, so that the axis of the bending fixed wheel 103 coincides with the axis of the center column 111, and cooperates with the moving wheel 101 and the moving wheel 2 102 to extrude the straight tube body 9 to achieve preliminary micro-bending, and then the moving wheel 101 and the moving wheel 2 102 can be relatively displaced to bend the straight tube body 9 into a U-shaped tube 6.

[0054] A threaded column 203 is rotatably connected to one end of the inner side of the limiting square opening 2. The threaded column 203 penetrates the moving rod 201 and is threadedly connected to the moving rod 201.

[0055] A threaded sleeve 206 is provided on the inner side of the moving block 205 , and a threaded rod 204 is rotatably connected to the other end of the inner side of the limiting square opening 2 , and the threaded rod 204 is threadedly connected to the threaded sleeve 206 .

[0056] Preferably, when the center rod 113 needs to be driven to move, the threaded rod 204 is rotated and threadedly connected with the threaded sleeve 206, thereby driving the threaded sleeve 206 to move. Under the guidance of a plurality of guide telescopic rods, the moving block 205 and the center rod 113 can be driven to move, thereby adjusting the position of the bending fixed wheel 103, and facilitating the loading of the straight pipe body 9;

[0057] When bending work is required, the threaded column 203 rotates to drive the moving rod 201 to move, thereby driving the limit block 202 to move and perform the bending work.

[0058] The threaded sleeve 206 is rotatably connected to the moving block 205, and a plurality of guiding telescopic rods are arranged between the threaded sleeve 206 and the threaded column 203. A torsion rod 207 penetrates and slides through the inner side of the threaded column 203, and a clamping plate 208 is fixedly connected to one end of the torsion rod 207, and clamping parts are fixedly connected to both ends of the clamping plate 208. An annular clamping groove 209 is provided at one end of the limiting square opening 2, and the annular clamping groove 209 is adapted to the clamping plate 208. A circular groove 210 is provided on the inner side of the annular clamping groove 209, and the diameter of the circular groove 210 is larger than the size of the clamping plate 208.

[0059] Preferably, an annular groove 209 and a clamping plate 208 are provided, and the two are adapted to each other. When the straight tube body 9 is loaded, the clamping plate 208 is also engaged with the annular groove 209, so that the torsion bar 207 and the threaded column 203 cannot rotate. The threaded column 203 is connected to the threaded sleeve 206 through a plurality of guide telescopic rods, so that the threaded sleeve 206 cannot rotate. A motor assembly is provided to drive the threaded rod 204. At this time, the threaded sleeve 206 cannot rotate, so that the threaded rod 204 drives the threaded sleeve 206 to move relatively, thereby driving the moving block 205 and the center rod 113 to move, and the bending fixed wheel 103 is reset and moved to squeeze and fix the straight tube body 9. Then the torsion bar 207 moves in the threaded column 203, pushing the clamping plate 208 to move into the circular groove 210, thereby disengaging from the annular clamping groove 209. At this time, the clamping plate 208 is in the circular groove 210 and can rotate freely, that is, the torsion bar 207 and the threaded column 203 can rotate, and the threaded column 203 can rotate at this time to drive the moving rod 201 to move, so as to perform the bending work, while on the other side, the threaded sleeve 206 also rotates inside the moving block 205. Since the threaded connection has a self-locking property, the relative position between the threaded rod 204 and the threaded sleeve 206 will not change, that is, the position of the bending fixed wheel 103 will not shift, thereby ensuring the stability of the bending forming, and having strong practicality;

[0060] That is to say, by engaging with the annular groove 209 and the clamping plate 208, the threaded column 203 is restricted from rotating, thereby restricting the threaded sleeve 206 from rotating. At this time, the threaded rod 204 can drive the threaded sleeve 206 and the moving block 205 to move, so that the bending fixed wheel 103 is reset, and then the clamping plate 208 moves away from the annular groove 209, so that the threaded column 203 rotates to drive the moving rod 201 to move, and the bending work is performed.

[0061] The length of the torsion rod 207 is greater than that of the threaded column 203 . One end of the torsion rod 207 is fixedly connected to the threaded sleeve 206 . When the threaded sleeve 206 contacts the end surface of the threaded column 203 , the clamping plate 208 moves into the circular groove 210 .

[0062] Preferably, in the initial state, the clamping plate 208 and the annular clamping groove 209 are mutually engaged and contact with the end surface of the threaded column 203, and the threaded rod 204 is driven to rotate by the motor assembly, and the threaded rod 204 drives the threaded sleeve 206 and the moving block 205 to move, so that the bending fixed wheel 103 moves and resets. While the threaded sleeve 206 moves, it pushes the torsion bar 207 to move, so that the clamping plate 208 is axially displaced in the annular clamping groove 209 until the bending fixed wheel 103 is completely reset and the threaded sleeve 206 contacts the end surface of the threaded column 203. At this time, the clamping plate 208 is also completely engaged with the threaded rod 204. The annular groove 209 separates and enters the circular groove 210, thereby automatically releasing the fixed restriction on the threaded column 203 and the threaded sleeve 206. At this time, the threaded rod 204 continues to rotate, driving the threaded sleeve 206 and the threaded column 203 to rotate synchronously, and the threaded column 203 can drive the movable rod 201 to move, thereby performing the bending work. In other words, by only setting a single motor assembly to drive the threaded rod 204 to rotate, the bending fixed wheel 103 can be driven to reset and move first, and then the movable rod 201 can be driven to move to perform the bending work, which has a high degree of automation and saves costs.

[0063] One end of the push rod 4 is fixedly connected to a push block 401 , and the push block 401 is driven by a cylinder 402 .
