Description

Technical Field

[0001] The invention relates to the technical field of copper tube expansion, and more specifically to an integrated machine for seamless copper tube expansion processing. Background Art

[0002] Copper tube expanding machine is a kind of equipment specially used to expand the ends of copper tubes. Its working principle is to apply high-strength pressure to the ends of copper tubes through the machine wheel to make them plastically deformed, thereby forming the required circular port. The circular port is mostly a bell mouth or a cup mouth, which is mainly used for pipe connection and sealing. It is widely used in the fields of construction, refrigeration, sanitation, gas, etc., mainly for pipe connection and maintenance, especially in the processing and manufacturing of copper tubes, it can quickly and efficiently complete the expansion operation.

[0003] When the existing copper tube expanding machine is used, the copper tube to be expanded is first fixed by a clamping system, and then a driving expanding rod is inserted into one end of the copper tube through a driving system, thereby applying high-strength pressure to the end of the copper tube to deform it into a cup-shaped port. However, when the copper tube expanding machine is used, because the diameters of the copper tubes to be expanded are different, it is necessary to replace expanding rods of different diameters to expand the copper tubes of different diameters. The existing replacement method is to first remove the expanding rod from the expanding machine, then find the expanding rod corresponding to the diameter of the copper tube to be expanded, reinstall the expanding rod on the expanding machine, and then expand the copper tube, which takes a lot of time and reduces the processing efficiency of the copper tube expanding machine.

[0020] (3) This scheme sets a fixing component.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 11 A seamless copper tube expansion processing integrated machine comprises a mounting platform 1, a mounting seat 2 is arranged on one side of the upper surface of the mounting platform 1, a clamping fixture 4 is fixedly connected to the other side of the upper surface of the mounting platform 1, an expansion rod 3 is arranged on the side of the outer surface of the mounting seat 2 close to the clamping fixture 4, a switching component 5 is arranged inside the mounting seat 2, and the switching component 5 comprises a No. 1 mounting groove 51 opened on the side of the outer surface of the mounting seat 2 close to the clamping fixture 4;

[0042] The outer circular surface of the expanding rod 3 is slidably sleeved with multiple expanding sleeves 52, and the expanding sleeves 52 are all located inside the No. 1 mounting groove 51, and one side of the outer circular surface of the expanding sleeve 52 is fixedly connected with an annular limit block 54, and the inside of the No. 1 mounting groove 51 is slidably connected with several evenly distributed moving plates 55, and the inner circular surface of the moving plate 55 is provided with an annular limit groove 53, and the annular limit blocks 54 are respectively rotatably connected to the inside of the annular limit blocks 54, and one side of the outer circular surface of the moving plate 55 is fixedly connected with a T-shaped block 56, and the T-shaped block 56 passes through the outer surface of the T-shaped block 56.

[0043] like Figure 1 , Figure 2 As shown, a fixing plate 10 is fixedly connected to the side of the mounting seat 2 on the upper surface of the mounting platform 1 away from the clamping fixture 4, and a telescopic rod 11 is fixedly connected to the side of the outer surface of the fixing plate 10 away from the telescopic rod 11. One end of the telescopic rod 11 passes through the fixing plate 10 and is fixedly connected to the mounting seat 2. A T-shaped groove 13 is provided on the upper surface of the mounting platform 1 below the mounting seat 2, and a T-shaped slide bar 14 is slidably connected inside the T-shaped groove 13. A mounting plate 12 is fixedly connected to the upper surface of the T-shaped slide bar 14, and the mounting plate 12 is fixedly connected to the lower surface of the mounting seat 2.

[0044] like Figure 2 , Figure 3 , Figure 4, Figure 5 As shown, a motor 15 is fixedly connected to a position near the fixed plate 10 on one side of the upper surface of the mounting plate 12, and a No. 2 chain gear 18 is fixedly connected to the output end of the motor 15. A No. 2 mounting groove 16 is opened on one side of the outer surface of the mounting seat 2 near the No. 2 chain gear 18, and a No. 1 chain gear 17 is rotatably connected inside the No. 2 mounting groove 16. The No. 1 chain gear 17 and the outer cylindrical surface of the No. 2 chain gear 18 are meshed with a transmission chain 19, and one end of the No. 1 chain gear 17 passes through the No. 1 mounting groove 51 and is fixedly connected to a turntable 20, and the outer surface of the turntable 20 is fixedly connected to one end of the expansion rod 3 away from the center position of the No. 1 chain gear 17.

[0045] When in use, first put the copper tube that needs to be expanded into the clamping and fixing device 4, clamp the copper tube through the clamping and fixing device 4, then start the telescopic rod 11 to drive the mounting seat 2 to move, thereby driving the expansion rod 3 to move toward the copper tube, and at the same time, the T-shaped sliding bar 14 is slidably connected with the T-shaped sliding groove 13, and the T-shaped sliding bar 14 and the mounting seat 2 are fixedly connected through the mounting plate 12, so that the mounting seat 2 can maintain stable movement, so that the expansion rod 3 can be accurately inserted into one end of the copper tube, and the copper tube one end is expanded.

[0046] However, because the diameters of the copper tubes to be expanded are different, it is necessary to replace the expansion rods 3 of different diameters on the copper tube expanding machine, and it is necessary to manually remove and install the expansion rods 3 from the expanding machine, which takes a lot of time and reduces the processing efficiency of the copper tube expanding machine. Therefore, a switching component 5 is set, and according to the different diameters of the copper tubes to be expanded, the T-shaped block 56 at the corresponding position is moved, thereby driving the moving plate 55 to move to the outside of the No. 1 installation groove 51, and then the corresponding expansion sleeve 52 is driven to move through the annular limit block 54. When the inclined surface at one end of the expansion sleeve 52 and the inclined surface at one end of the expansion rod 3 are located on the same conical surface, the expansion rod 3 and the expansion sleeve 52 jointly form a new expansion rod 3, so that the new expansion rod 3 corresponds to the diameter of the copper tube, so that copper tubes of different diameters can be expanded, and then the expansion rods 3 of different diameters can be quickly switched, which improves the switching speed of the expansion rod 3, thereby improving the processing efficiency of the copper tube expanding machine.

[0047] like Figure 4 , Figure 5As shown, there are five expanding sleeves 52, and the five expanding sleeves 52 are mutually socketed, and the lengths of the five expanding sleeves 52 are mutually reduced, and a connecting component 6 is provided between the expanding rod 3 and the expanding sleeve 52, and the connecting component 6 includes a No. 1 external tooth groove 61 on the side of the outer circular surface of the expanding rod 3 close to the turntable 20, and the inner circular surfaces of the five expanding sleeves 52 close to the turntable 20 are all provided with internal tooth grooves 63, and the outer circular surfaces of the five expanding sleeves 52 except the outermost expanding sleeve 52 are all provided with No. 2 external tooth grooves 62, and the five internal tooth grooves 63 are respectively slidably connected with the four No. 2 external tooth grooves 62 and the No. 1 external tooth groove 61.

[0048] In the above embodiment, the expansion sleeve 52 is driven to move by moving the T-shaped block 56. When the inclined surface of the expansion sleeve 52 and the inclined surface of the expansion rod 3 are located on the same conical surface, the expansion rod 3 and the expansion sleeve 52 form a new expansion rod 3, so that expansion rods 3 of different diameters can be quickly switched. However, when the diameter of the expansion rod 3 required is large, it is necessary to move multiple T-shaped blocks 56 to drive multiple expansion sleeves 52 to move, which takes a lot of time, reduces the switching efficiency of the switching component 5, and thus reduces the processing efficiency of the copper tube expansion machine. Therefore, a connecting component 6 is provided. When it is necessary to move multiple T-blocks 56, first move a T-block 56 connected to the larger expanding sleeve 52 among the multiple T-blocks 56, thereby driving the expanding sleeve 52 to move. Then, through the cooperation of the inner tooth groove 63 and the second outer tooth groove 62, the expanding sleeve 52 with a smaller diameter than the expanding sleeve 52 can be driven to move simultaneously. Thus, by moving one T-block 56, multiple expanding sleeves 52 can be driven to move simultaneously, and then the diameter of the expanding rod 3 can be adjusted at one time, thereby improving the switching efficiency of the switching component 5, thereby improving the processing efficiency of the copper tube expanding machine. Moreover, through the cooperation of the inner tooth groove 63 and the first outer tooth groove 61, when the expanding rod 3 rotates, the expanding sleeve 52 is also driven to rotate, so that the expanding rods 3 of different diameters can be rotated and inserted into one end of the copper tube, ensuring that the expanding operation can be carried out smoothly, further improving the processing efficiency of the copper tube expanding machine.

[0049] like Figure 3 , Figure 6 , Figure 7 , Figure 8As shown, the movable plates 55 are provided with five, and a fixing assembly 7 is provided between the movable plate 55 and the No. 1 mounting groove 51. The fixing assembly 7 includes five evenly distributed limiting baffles 71 fixedly connected to the inner circular surface of the No. 1 mounting groove 51, one side of the outer surface of the limiting baffle 71 is provided with four annular evenly distributed No. 1 through grooves 74, one side of the outer surface of the movable plate 55 is fixedly connected with four annular evenly distributed fixing blocks 72, and the four fixing blocks 72 are respectively engaged with the four No. 1 through grooves 74, one end of the inner wall of the four No. 1 through grooves 74 is provided with a No. 1 slide groove 75, one end of the outer surface of the four fixing blocks 72 is provided with a No. 1 clamping groove 73, and the positions of the No. 1 clamping groove 73 and the No. 1 slide groove 75 are close to each other, and the four No. 1 slide grooves 75 are slidably connected with a No. 1 sliding clamping block 76, and a No. 1 spring 711 is provided on the side of the outer surface of the No. 1 sliding clamping block 76 away from the fixed block 72.

[0050] like Figure 7 , Figure 8 As shown, a common annular slide groove 77 is provided on one side of the inner wall of the four No. 1 slide grooves 75, and an annular swivel block 78 is rotatably connected inside the annular slide groove 77, and the annular swivel block 78 is fixedly connected to the four No. 1 sliding blocks 76, and a No. 2 slide groove 79 is provided on the side of the inner wall of the annular slide groove 77 away from the side of the No. 1 sliding block 76, and a control rod 710 is slidably connected inside the No. 2 slide groove 79, and the control rod 710 is fixedly connected to the annular swivel block 78.

[0051] like Figure 7 , Figure 8 , Fig. 9 As shown, a reinforcing component 8 is provided at the other end of the inner wall of the No. 1 through groove 74, and the reinforcing component 8 includes a No. 3 slide groove 81 opened at the other end of the inner wall of the four No. 1 through grooves 74, and the four No. 3 slide grooves 81 are all slidably connected with No. 2 sliding blocks 82, and the other end of the outer surface of the four fixed blocks 72 is provided with a No. 2 groove 89, and the outer surface of the four No. 2 sliding blocks 82 is provided with a No. 2 spring 83 on the side away from the fixed block 72.

[0052] like Fig. 9 As shown, a No. 4 slide groove 84 is provided on the inner wall of the four No. 3 slide grooves 81 near the side of the annular rotating block 78, and the interiors of the four No. 4 slide grooves 84 are slidably connected with arc-shaped racks 85, and the four arc-shaped racks 85 are respectively fixedly connected to the four No. 2 sliding blocks 82, and connecting grooves 86 are provided between the four No. 4 slide grooves 84 and the annular slide groove 77, and gears 87 are rotatably connected inside the four connecting grooves 86, and arc-shaped tooth grooves 88 are provided on the inner circular surface of the annular rotating block 78 near the four gears 87, and the gears 87 are meshedly connected with the arc-shaped tooth grooves 88 and the arc-shaped racks 85.

[0053] In the above embodiment, the expansion sleeve 52 is driven to move by moving the T-shaped block 56. When the inclined surface of the expansion sleeve 52 and the inclined surface of the expansion rod 3 are located on the same conical surface, the expansion rod 3 and the expansion sleeve 52 form a new expansion rod 3 together, so that expansion rods 3 of different diameters can be quickly switched. However, because the expansion rod 3 and the expansion sleeve 52 need to be inserted into one end of the copper tube when expanding the copper tube, the copper tube will push the expansion sleeve 52 in the opposite direction to move inside the No. 1 installation groove 51, resulting in the expansion sleeve 52 being unable to expand one end of the copper tube, affecting the use effect of the switching component 5 and reducing the processing efficiency of the copper tube expanding machine.

[0054] Therefore, a fixing assembly 7 is provided. When the T-shaped block 56 and the movable plate 55 drive the expansion sleeve 52 to move, the fixing block 72 is simultaneously driven to move toward the limit baffle 71. When the inclined surface of the expansion sleeve 52 and the inclined surface of the expansion rod 3 are located on the same conical surface, the fixing block 72 is inserted into the No. 1 through groove 74, and then the No. 1 sliding block 76 is driven to move in the No. 1 slide groove 75 by the No. 1 spring 711, so that the No. 1 sliding block 76 is inserted into the No. 1 groove 73, thereby fixing the fixing block 72 in the No. 1 through groove 74, and then fixing the position of the movable plate 55, so that the expansion sleeve 52 and the expansion rod 3 are fixed. The expansion sleeve 52 is fixed, so that when the expansion rod 3 and the expansion sleeve 52 are inserted into one end of the copper tube, the copper tube is prevented from pushing the expansion sleeve 52 in the reverse direction, thereby ensuring the use effect of the switching component 5 and improving the processing efficiency of the copper tube expansion machine. Then, by pressing down the control rod 710, the control rod 710 moves downward in the second slide groove 79, thereby driving the annular rotating block 78 to rotate in the annular slide groove 77, and at the same time driving the No. 1 sliding block 76 to move into the No. 1 slide groove 75, so that the No. 1 sliding block 76 is pulled out from the No. 1 slot 73, thereby releasing the fixation of the expansion sleeve 52 and allowing the expansion sleeve 52 to move.

[0055] The lock body 72 is fixed in the No. 1 slot 74 by inserting the No. 1 sliding block 76 on one side into the No. 1 slot 73, thereby fixing the fixing block 72 in the No. 1 slot 74, thereby fixing the expansion sleeve 52 and the expansion rod 3. However, because the fixing block 72 is fixed to the No. 1 slot 74 only through one side, the fixing effect of the fixing block 72 is poor, which reduces the use effect of the fixing assembly 7. Therefore, a reinforcing assembly 8 is provided. When the No. 1 sliding block 76 is inserted into the No. 1 slot 73, the No. 2 sliding block 82 is driven by the No. 2 spring 83 to move in the No. 3 slide slot 81, so that the No. 2 sliding block 82 is inserted into the No. 2 slot 89, thereby fixing the fixing block 72 in the No. 1 slot 74 through both sides, so that the fixing block 72 can be stably fixed in the No. 1 slot 74, thereby improving the use effect of the fixing assembly 7. Then, when the control rod 710 moves downward and drives the annular rotating block 78 to rotate, it also drives the arc-shaped tooth groove 88 to rotate, thereby driving the gear 87 to rotate inside the connecting groove 86, and then drives the arc-shaped rack 85 to move in the No. 4 slide groove 84, and at the same time drives the No. 2 sliding block 82 to move into the No. 3 slide groove 81, so that the No. 2 sliding block 82 is pulled out from the No. 2 groove 89. When the No. 1 sliding block 76 is released from the fixed block 72, the No. 2 sliding block 82 can also release the fixation of the fixed block 72.

[0056] like Figure 7 , Figure 8 , Fig.10 , Fig.11 As shown, a positioning assembly 9 is arranged between the No. 2 slide groove 79 and the control rod 710, a No. 2 through groove 91 is provided at a position inside the No. 2 slide groove 79 on one side of the outer surface of the control rod 710, two No. 5 slide grooves 92 are provided at positions near the No. 2 through groove 91 on both sides of the inner wall of the No. 2 slide groove 79, and a No. 3 sliding block 93 is slidably connected inside the four No. 5 slide grooves 92, and a No. 3 spring 94 is provided on the side of the outer surface of the four No. 3 sliding blocks 93 away from the No. 2 through groove 91, a No. 6 slide groove 95 is provided on one side of the inner wall of the No. 2 through groove 91, and a sliding push block 96 is slidably connected inside the No. 6 slide groove 95, and a No. 1 straight rod 97 is fixedly connected to the side of the outer surface of the sliding push block 96 away from the No. 2 through groove 91, and the No. 1 straight rod 97 runs through the control rod 710.

[0057] like Fig.11 As shown, a No. 7 slide groove 98 is provided at a position corresponding to the No. 1 straight rod 97 on one end of the outer surface of the control rod 710, and a No. 2 straight rod 99 is slidably connected inside the No. 7 slide groove 98, and the No. 2 straight rod 99 is fixedly connected to the No. 1 straight rod 97, and a No. 4 spring 910 is provided on one end of the outer surface of the No. 2 straight rod 99 close to the No. 1 straight rod 97.

[0058] In the above embodiment, the annular rotating block 78 is driven to rotate by the control rod 710, thereby controlling the simultaneous movement of the No. 1 sliding block 76 and the No. 2 sliding block 82, and further controlling the fixation of the No. 1 sliding block 76 and the No. 2 sliding block 82 to the fixed block 72. However, when the copper tube expanding machine is working, vibrations will be generated, causing the annular rotating block 78 to rotate automatically, making it easy for the No. 1 sliding block 76 and the No. 2 sliding block 82 to fix the fixed block 72 to loosen, thereby reducing the use effect of the fixing component 7. Therefore, a positioning assembly 9 is provided. When the control rod 710 drives the annular swivel block 78 to rotate upward, the fixing block 72 is fixed by the No. 1 sliding block 76 and the No. 2 sliding block 82. At the same time, the two No. 3 sliding blocks 93 on the upper side are driven to move closer to each other by the two No. 3 springs 94 on the upper side, so that the two No. 3 sliding blocks 93 on the upper side are inserted into the No. 2 through slots 91 at the same time, thereby fixing the control rod 710 and preventing the annular swivel block 78 from rotating. When the control rod 710 drives the annular swivel block 78 to rotate downward, the fixing of the No. 1 sliding block 76 and the No. 2 sliding block 82 on the fixed block 72 is released. At the same time, the two No. 3 sliding blocks 93 on the lower side are driven to move closer to each other by the two No. 3 springs 94 on the lower side, so that the two No. 3 sliding blocks 93 on the lower side are inserted into the No. 2 through slots 91 at the same time, thereby fixing the control rod 710 and preventing the annular swivel block 78 from rotating, thereby improving the use effect of the fixing assembly 7. Then, by pressing the No. 2 straight rod 99, the No. 1 straight rod 97 is driven to move, thereby driving the sliding push block 96 to the outside of the No. 6 slide groove 95, so that the sliding push block 96 is inserted into the No. 2 through groove 91, thereby pushing the two No. 3 sliding blocks 93 to move to the outside of the No. 2 through groove 91 at the same time, thereby releasing the fixation of the two No. 3 sliding blocks 93 on the control rod 710, facilitating the movement of the control rod 710, and the No. 2 straight rod 99 can be driven to move to the outside of the No. 7 slide groove 98 through the No. 4 spring 910.

[0059] Instructions for use: First, place the copper tube to be expanded into the clamping and fixing device 4, clamp and fix the copper tube, then start the switching component 5 according to the different diameters of the copper tube to be expanded, and simultaneously start the connecting component 6 to quickly switch the diameter of the expanding rod 3, and then fix the fixing block 72 to the No. 1 through groove 74 through the fixing component 7, so as to fix the expanding sleeve 52 and the expanding rod 3, and simultaneously start the reinforcing component 8 to strengthen the stability of the expansion sleeve 52 between the expansion rod 3, and then start the positioning component 9 to fix the control rod 710 to prevent the annular rotating block 78 from rotating, so as to ensure the stability of the expansion sleeve 52 and the expansion rod 3, and then start the telescopic rod 11 to drive the expansion rod 3 to move toward one end of the copper tube, and simultaneously start the motor 15 to drive the expansion rod 3 to rotate, so that the expansion rod 3 is rotated and inserted into one end of the copper tube, and the copper tube is expanded at one end.
