[0038] 3. The present invention reversely rotates the fastening bolts threadedly connected to the top of the L-shaped plate to move the displacement plate downward on the peripheral side surfaces of the two guide rods until the arc-shaped tooth plate fixed at the bottom of the displacement plate engages with the rotating teeth, thereby preventing the rotating round rod from rotating circumferentially inside the rotating sleeve during the subsequent punching operation of the condenser copper tube to be punched, resulting in the disappearance of the fitting support effect between the two inner supporting arc-shaped plates and the inner wall of the condenser copper tube to be punched.

[0039] 4. The present invention uses an internal support member to internally support the condenser copper tube to be punched, so as to facilitate the later punching operation of the condenser copper tube to be punched, to prevent the punching part of the condenser copper tube to be punched from being dented due to excessive external force during the punching process, and to avoid cracks around the punched part.

[0060] The specific application of this embodiment 1 is:

[0061] When the copper tube 8 supported inside and outside is being punched, the hydraulic punching cylinder 404 is started, driving the punching die 405 fixed at the telescopic end of the hydraulic punching cylinder 404 to descend, and gradually approach the outer peripheral side of the copper tube 8 after the inner and outer supports, so that the copper tube 8 is punched through the descending process of the punching die 405.

The entire waste collection process does not need to add other structures, and the waste collection process can be completed only through its own structure, which brings certain convenience to the operators.

[0063] For example 2, please refer to Figure 1-14, the second embodiment makes the following improvements on the basis of the first embodiment. Specifically, two symmetrical first T-shaped grooves 302 are opened on the top of the bottom plate 301, and two symmetrical external support frames 303 are slidably matched between the two first T-shaped grooves 302. The tops of the two external support frames 303 are fixed with columns 304, and the tops of the columns 304 are fixed with first V-shaped support plates 305. Two vertical plates 306 are fixed between the two external support frames 303 on the top of the bottom plate 301, and a second V-shaped support plate 307 arranged parallel to the first V-shaped support plate 305 is fixed between the two vertical plates 306; a dual-axis motor 308 is fixed on the top of the bottom plate 301, and an output shaft of the dual-axis motor 308 is fixed with a bidirectional threaded rod 309 threadedly connected to the two external support frames 303, and the bidirectional threaded rod 309 is located on the side surface A limit ring 310 is fixed in the middle position; two symmetrical discharge grooves 412 are opened on the side of the punching die 405, and lifting plates 413 are slidably fitted inside the two discharge grooves 412; a connecting flange 409 fixedly connected to the telescopic end of the hydraulic punching cylinder 404 is fixed on the side of the punching die 405, and two symmetrical limiting rods 410 are fixed at the bottom of the connecting flange 409, and the limiting rods 410 are slidably fitted with the lifting plates 413, and a limiting plate 411 is fixed at the bottom of the limiting rod 410, and an elastic spring 414 that is sleeved and fitted on the side of the limiting rod 410 is fixed between the lifting plates 413 and the connecting flange 409; a lifting plate 417 that is slidably fitted inside the punching die 405 is fixed between the two lifting plates 413, and an inner ejection plate ball 418 is fixed at the bottom of the lifting plate 417.

[0064] The specific application of this second embodiment is:

[0065] Before punching the condenser copper tube to be punched, the entire mechanism places the condenser copper tube to be punched inside the first V-shaped support plate 305 and the second V-shaped support plate 307, so as to provide preliminary external support for the condenser copper tube to be punched. After the external support is completed, the internal support for the condenser copper tube to be punched is continued to be performed to facilitate the subsequent punching operation.

[0066] When the punching operation begins, the hydraulic punching cylinder 404 is started, driving the punching die 405 fixed to the telescopic end of the hydraulic punching cylinder 404 to descend, and gradually approaching the outer peripheral side of the condenser copper tube to be punched after the inner and outer supports, so that the condenser copper tube to be punched is punched through the descending process of the punching die 405.

[0067] When the punching operation of the condenser copper tube to be punched is completed, the hydraulic punching cylinder 404 starts to rise, and thereby drives the punching die 405 to rise. When the punching die 405 is rising, the elastic spring 414 compressed inside it starts to reset, and gradually drives the lifting plate 417 between the two lifting plates 413 and the inner ejection plate ball 418 fixedly connected to the bottom of the lifting plate 417 to move downward inside the punching die 405, so as to eject the waste material after the punching is completed, so as to avoid the waste material remaining inside the punching die 405 from affecting the later punching operation process, and improve the efficiency of the punching operation;

[0068] When it is necessary to punch holes in condenser copper tubes of different lengths, start the dual-axis motor 308 and the bidirectional threaded rod 309 with an output shaft fixed thereon, and drive the two external support frames 303 to move relatively far away or close to each other on the top of the base plate 301, so as to achieve the external support effect for the condenser copper tubes of different lengths to be punched, and prevent them from tilting due to unstable center of gravity when punching the condenser copper tubes of different lengths to be punched, so as to avoid affecting the punching process of the condenser copper tubes of different lengths to be punched.

[0070] The specific application of this embodiment 3 is:

[0071] Before using this mechanism, the condenser copper tube to be punched is placed on this mechanism and firstly provided with external support. After the external support is completed, the U-shaped slide plate 601 in the inner support member 6 is slidably plugged on the two rectangular horizontal plates 313 until one side of the two U-shaped slide plates 601 respectively fits with one side of the U-shaped slide plate 601, and then the rectangular horizontal plate 313 and the U-shaped slide plate 601 are connected and fixed using external bolts. After the connection and fixation is completed, the entire inner support member 6 is located on the condenser copper tube to be punched, so as to facilitate the internal support of the condenser copper tube to be punched during the punching operation, so as to prevent the punching part of the condenser copper tube to be punched from being sunken due to excessive external force during the punching process, and to avoid cracks around the punched part.

[0072] After the inner support member 6 is inserted and matched to the inside of the copper tube of the condenser to be punched, the gear ring 701 in the adjustment member 7 is first moved between the two symmetrically distributed arc-shaped clamping plates 728, and then the rotating bolt 720 that is matched through the bearing on one side of the other U-shaped side baffle plate 718 is rotated, so that the cross ring plate 721 moves on the limiting cross bar 719 and the rotating sleeve 704 at the same time, thereby driving the two hinged arms 726 hingedly matched between the second hinge seat 725 and the first hinge seat 724 to perform relative expansion movement, so that the two I-shaped slide rail blocks 723 slide simultaneously and separately inside the two U-shaped side panels 722, and Gradually move away from each other, thereby driving the two arc-shaped clamping plates 728 fixed on the opposite side of the two I-shaped slide rail blocks 723 to move away from each other, and engage with the annular groove 702 opened on the inner wall of the gear ring 701, until the plug-in round rods 729 fixed on the outer walls of the two arc-shaped clamping plates 728 are respectively plugged and matched with the two plug-in round grooves 703, and then stop rotating the rotating bolt 720, so as to complete the movable installation and fixation of the gear ring 701 in the adjustment member 7, and finally be in a state of mutual meshing with the driving gear 311 fixed on the other output shaft of the dual-axis motor 308, so as to facilitate the subsequent punching operation in the circumferential direction of the copper tube of the condenser to be punched;

[0073] After the above operation is completed, the fastening bolts 713 threadedly connected to the top of the L-shaped plate 712 begin to rotate, so that the displacement plate 714 moves upward on the peripheral side of the two guide rods 716 until the arc-shaped tooth plate 715 fixed at the bottom of the displacement plate 714 is separated from the rotating tooth 710. Then, the rotating round rod 705 continues to rotate so that the rotating round rod 705 rotates inside the rotating sleeve 704, thereby driving the two sliding round rods 608 fixed on one side of the two slide rail blocks 605 to slide simultaneously inside the two arc grooves 707 penetrated through one side of the rotating disk 706, thereby driving the two slide rail blocks 605 to slide relative to each other inside the two rectangular slide grooves at the same time, until the inner supporting arc plate 606 fixed on the opposite side of the two slide rail blocks 605 is in contact with the inside of the copper tube of the condenser to be punched, then the rotation of the rotating round rod 705 is stopped, and then the rotation is reversed. The fastening bolts 713 threadedly connected to the top of the rotating L-shaped plate 712 allow the displacement plate 714 to move downward on the peripheral side surfaces of the two guide rods 716 until the arc-shaped tooth plate 715 fixed at the bottom of the displacement plate 714 is engaged with the rotating tooth 710, thereby preventing the rotating round rod 705 from rotating circumferentially inside the rotating sleeve 704 during the later punching operation of the condenser copper tube to be punched, resulting in the disappearance of the fitting support effect between the two inner supporting arc plates 606 and the inner wall of the condenser copper tube to be punched. The entire process is carried out by the inner support member 6 to internally support the condenser copper tube to be punched, so as to facilitate the later punching operation of the condenser copper tube to be punched. The punching part of the condenser copper tube to be punched is prevented from being sunken due to excessive external force during the punching process, and cracks are avoided around the punched part.

[0074] When it is necessary to perform linear punching operation on the peripheral side of the copper tube of the condenser to be punched, the forward and reverse motor 318 is started to drive the threaded screw 319 fixed to the output shaft of the forward and reverse motor 318 to rotate, so as to change the position of the threaded hole 416 on the peripheral side of the threaded screw 319 and then change the position of the guide horizontal plate 415 in the horizontal groove 320 provided on the outer side of the L-shaped side plate 314, so as to realize the linear punching process at different positions of the peripheral side of the copper tube of the condenser to be punched;

[0075] Similarly, when it is necessary to perform circumferential punching operations on the circumferential side surface of the condenser copper tube to be punched, the driving gear 311 fixed to the other output shaft of the dual-axis motor 308 is started to drive the condenser copper tube to be punched, which has been supported internally and externally, to rotate circumferentially, thereby realizing circumferential punching operations at different positions on the circumferential side surface of the condenser copper tube to be punched.
