Description

Technical Field

[0001] The invention relates to the technical field of ground source heat pump connection component processing, and in particular to ground source heat pump connection component molding and processing equipment. Background Art

[0002] Copper pipe joints are one of the common connection components in ground source heat pump systems, mainly composed of a main pipe and several linearly arranged branch pipes. During the production and molding process of copper pipe joints, the branch pipes need to be welded to the main pipe to achieve the sealing and stability of the internal pipe connection of the copper pipe joints, thereby ensuring that the copper pipe joints used in the ground source heat pump system can always operate normally and be used effectively.

[0003] At present, there are the following disadvantages when welding main pipes and branch pipes: 1. When welding, the worker needs to hold the end of the main pipe first, then clamp the branch pipe with the welding ring with pliers and press it against the corresponding position of the main pipe, and then place the two on the high-frequency welding machine for welding. Only after welding is completed can the next branch pipe be welded. For operations that require welding of several branch pipes, the forming process is inefficient, which seriously affects the production progress. In addition, during the welding process, workers need to approach the high-frequency welding machine to operate, which poses safety risks such as burns and electric shock, increasing the possibility of worker injury; 2. In the process of welding copper pipe joints, since workers need to hold and clamp, there will be deviations in the welding position and angle, resulting in unstable welding quality. Copper pipe joints are prone to welding defects or quality problems, and due to the uncertainty of manual operation, the angle and strength of each welding will be different, which in turn leads to reduced consistency of the welded joints, affecting the quality stability of batch-formed copper pipe joints.

[0037] See also Figure 1 and Figure 3 The alignment part 43 includes a tripod 431, a supporting plate 432, a hydraulic cylinder 433, a lower pressure plate 434 and an equipment cross plate 435. Two left-right symmetrical tripods 431 are fixedly installed on the upper end surface of the supporting frame 3. The upper ends of the two tripods 431 are jointly fixedly installed with a supporting plate 432. A hydraulic cylinder 433 with a telescopic end passing through the lower end surface is fixedly installed on the supporting plate 432. The telescopic end of the hydraulic cylinder 433 is fixedly installed with a lower pressure plate 434 located below the supporting plate 432. The lower end of the lower pressure plate 434 is fixedly installed with an equipment cross plate 435 located directly below it through a set connecting column.

[0038] During specific work, when the copper pipe joint needs to be formed, the worker first places the main pipe between the sliding cross bars 412 on both sides, and then starts the first motor 413 to rotate the bidirectional screw, thereby bringing the sliding cross bars 412 on both sides closer together until the two ends of the main pipe are pressed. At this time, the second motor 425 is in an unstarted state, so that the pressing blocks 423 on the same sliding cross bar 412 are all in a state of being close to each other, and the pressing blocks 423 are all located in the corresponding main pipe ends, and then the position of the main pipe welding hole is manually adjusted so that the welding hole faces upward.

[0039] Then, the hydraulic pump fixedly mounted on the supporting plate 432 is started, so that the hydraulic cylinder 433 descends with the equipment cross plate 435 through the lower pressure plate 434 until the pre-clamping portion 51 is inserted into the welding hole of the main pipe, and then the hydraulic cylinder 433 is stopped. Then, the welding hole of the main pipe is internally expanded and fixed through the cooperation of the inner support portion 53 and the driving portion 54, so as to calibrate the position of the main pipe to ensure the accuracy of the position of the welding hole.

[0040] Then, the second motors 425 on both sides are started to rotate with the first central axis 426, and the first screw 424 is rotated synchronously with the cooperation of multiple first bevel gears and second bevel gears, thereby driving the pressure block 423 to move away synchronously until the pressure block 423 expanded on all sides presses against the inner ring wall at both ends of the main pipe, thereby completing the internal support fixation of the two ends of the main pipe, ensuring that the main pipe always remains in a stable state during the subsequent welding process, and after the main pipe is fixed, the internal support part 53 cooperates with the driving part 54 to release the fixation of the main pipe welding hole, and reversely start the hydraulic cylinder 433 to lift the equipment cross plate 435.

[0041] See also Figure 6 , Figure 7 and Figure 8The pre-clamping portion 51 includes a positioning cylinder 511, a third slideway 512, a connecting slider 513, a pressing sleeve 514, a circular slide plate 515 and a positioning buckle 516. A plurality of positioning components are evenly fixedly installed on the lower end surface of the equipment cross plate 435. Each positioning component is composed of three positioning cylinders 511 distributed in a linear array. The positioning cylinder 511 is penetrated by two third slideways 512 symmetrical about its axis. Connecting sliders 513 are slidably installed in the third slideways 512. The ends of the two connecting sliders 513 that are away from each other are jointly fixedly installed with a pressing sleeve 514 that is slidably connected to the outer ring wall of the positioning cylinder 511. The ends of the two connecting sliders 513 that are close to each other are jointly fixedly installed with a circular slide plate 515 located in the positioning cylinder 511. A positioning buckle 516 is fixedly installed on the inner side of the pressing sleeve 514.

[0042] See also Figure 6 , Figure 7 and Figure 8 The pressing part 52 includes a fourth slide 521, a shaft 522, an inner push rod 523, a connecting tube 524 and an upper push circular plate 525.

An upper push circular plate 525 located below the inner push rod 523 is fixedly installed at the lower end of the connecting tube 524.

[0043] In the specific work, after the main pipe is fixed, the worker puts the branch pipe with the welding ring on the positioning cylinder 511. During the process of inserting the branch pipe into the positioning cylinder 511, the upper end of the branch pipe pushes the pressing sleeve 514 upward, so that the circular sliding plate 515 moves upward in the positioning cylinder 511 through the connecting slider 513, and the upper circular plate 525 is pulled upward through the connecting cylinder 524. The upward movement of the upper circular plate 525 pushes the lower end of the surrounding inner rod 523 upward, so that the inner rod 523 is The shaft 522 rotates, and the upper end of the inner push rod 523 moves to the side away from the positioning tube 511. When the pressing sleeve 514 moves upward to the positioning buckle 516 buckled into the positioning groove, the upper push circular plate 525 stops moving, and the inner push rod 523 that expands around the periphery presses and supports the inner ring wall of the branch pipe, thereby determining the height of the branch pipe and pre-positioning and clamping it. Subsequently, all branch pipes are loaded one by one in the same way, thereby ensuring the accuracy of the height of each branch pipe.

[0044] See also Figure 6 , Figure 7 and Figure 8The inner support part 53 includes a screw sleeve 531, a second screw rod 532, a limiting slide rod 533 and an inner support plate 534. A plurality of screw sleeves 531 are installed through the bearing in a circular array at the lower end of the positioning cylinder 511. The second screw rod 532 is threadedly connected in the screw sleeve 531.

The second screw 532 and the limiting slide rod 533 that are opposite to each other up and down and away from the positioning cylinder 511 are both fixedly installed with an inner support plate 534 at one end.

[0045] See also Figure 6 and Figure 8 The driving part 54 includes a second central axis 541, a transmission rod 542 and a third motor 543. The second central axis 541 located in the connecting cylinder 524 is installed through a bearing at the center of the positioning cylinder 511. The second central axis 541 is coaxial with the connecting cylinder 524, the upper circular plate 525 and the circular slide plate 515.

The transmission rod 542 and the second central axis 541 are transmission-connected through a transmission bevel gear set.

[0046] During specific operation, when it is necessary to fix the welding hole of the main pipe through the cooperation of the inner support part 53 and the driving part 54, the equipment cross plate 435 is inserted into the welding hole of the main pipe with the positioning cylinder 511 under the action of the hydraulic cylinder 433. At this time, the inner support plate 534 is just located at the welding hole. At this time, the third motor 543 can be started to rotate the transmission rod 542, and with the cooperation of the transmission bevel gear set, it can rotate synchronously with the second central shaft 541. The second central shaft 541 will drive the screw sleeve 511 in the positioning cylinder 511 under the cooperation of the third bevel gear and the fourth bevel gear. 31 rotates synchronously. At this time, under the limitation of the limiting slide bar 533 on the inner support plate 534, the screw sleeve 531 is synchronously moved to the side away from the positioning tube 511 through the second screw rod 532 with the inner support plate 534 until the inner support plates 534 on all sides are pressed against the inner wall of the welding hole, thereby completing the adjustment of the main pipe position through the inner support of the welding hole. When the fixation is completed, it is only necessary to start the third motor 543 in reverse to retract the inner support plates 534 on all sides through the cooperation of the inner support part 53 and the driving part 54, so as to release the fixation of the welding hole.

[0047] After the pre-clamping portion 51 cooperates with the pressing portion 52 to complete the pre-clamping and fixing of the multiple branch pipes, the third motor 543 is started to expand the internal support plates 534 on the four sides of the positioning tube 511 through the cooperation of the internal support portion 53 and the driving portion 54 until the internal support plates 534 are pressed against the inner ring wall of the branch pipe, and the third motor 543 is stopped to complete the synchronous internal support and fixation of the multiple branch pipes, so that the branch pipes remain in a stable state during the welding process.

[0050] During specific operation, after the clamping mechanism 5 completes the fixation of the several branch pipes, the hydraulic pump is started to make the hydraulic cylinder 433 move downward with the fixed several branch pipes through the equipment cross plate 435 until the lower end of the branch pipe is synchronously pressed against the main pipe welding hole. At this time, the docking rod 611 will be inserted into the corresponding docking groove 612 with the docking block. At this time, the locking hole 613 and the sliding hole 614 are in a coaxial position. Then the fourth motor 622 can be started to rotate the turntable 623 to a certain angle, so that the locking column 615 will be pushed out of the sliding hole 614 and inserted into the locking hole 613 through the hinged rod 621, so as to lock the position of the lower pressure plate 434 and the sliding cross bar 412, thereby locking the relative positions of the several branch pipes and the main pipe, so as to ensure that the two always remain in a stable state during the welding process and ensure the accuracy of the welding position.

[0051] Then the electric slide rail 2 can be started to move the carrying frame 3. When the connection between the branch pipe and the main pipe is moved to the high-frequency welding machine 7, the high-frequency welding machine 7 is started to weld the connection. At this time, the welding ring on the branch pipe will melt and fuse the connection. After the welding is completed, the high-frequency welding machine 7 is stopped, and the next connection is moved to the high-frequency welding machine 7. Then this process is repeated until the welding of the copper pipe joint is completed.

[0052] After welding is completed, the fourth motor 622 is started in reverse to release the lock on the clamping mechanism 5 and the fixing mechanism 4, and then the second motor 425 is started in reverse to release the lock on the main pipe, and the first motor 413 is started in reverse to release the pressure on the main pipe, and then the third motor 543 is started in reverse to release the internal support fixation of the branch pipe, and then the copper pipe joint is directly pulled downward to complete the forming process of the copper pipe joint.

[0053] See also Figure 1-Figure 10 Working principle: When the copper pipe joint needs to be formed, the worker first places the main pipe between the sliding cross bars 412 on both sides, then starts the first motor 413 to press the two ends of the main pipe through the fixing part 41, and then inserts it into the welding hole of the main pipe through the alignment part 43 and the pre-clamping part 51, and calibrates the position of the main pipe through the inner support part 53 and the driving part 54, and then starts the second motors 425 on both sides to fix the inner supports at both ends of the main pipe through the clamping part 42, and after the fixation of the main pipe is completed, the fixation of the main pipe welding hole is released through the cooperation of the inner support part 53 and the driving part 54, and the hydraulic cylinder 433 is started in the reverse direction to bring the equipment cross plate 435 up.

[0054] Then the worker puts the branch pipe with the welding ring on the positioning tube 511, and completes the pre-clamping and fixing of the several branch pipes through the cooperation of the pre-clamping part 51 and the pressing part 52, and then starts the third motor 543 to expand the internal support plate 534 around the positioning tube 511 through the cooperation of the internal support part 53 and the driving part 54, so as to complete the synchronous internal support and fixation of the several branch pipes, and then aligns the welding holes of the branch pipe and the main pipe through the alignment part 43, and locks the relative positions of the several branch pipes and the main pipe through the locking mechanism 6.

[0055] Then the electric slide rail 2 can be started to move the carrying frame 3. When the connection between the branch pipe and the main pipe is moved to the high-frequency welding machine 7, the high-frequency welding machine 7 is started to weld the connection. At this time, the welding ring on the branch pipe will melt and fuse the connection. After the welding is completed, the high-frequency welding machine 7 is stopped, and the next connection is moved to the high-frequency welding machine 7. Then this process is repeated until the welding of the copper pipe joint is completed.

[0056] After welding is completed, the fourth motor 622 is started in reverse to release the lock on the clamping mechanism 5 and the fixing mechanism 4, and then the second motor 425 is started in reverse to release the lock on the main pipe, and the first motor 413 is started in reverse to release the pressure on the main pipe, and then the third motor 543 is started in reverse to release the internal support fixation of the branch pipe, and then the copper pipe joint is directly pulled downward to complete the forming process of the copper pipe joint.
