Description

Technical Field

[0001] This utility model relates to the field of finned tube tooth forming technology, and in particular to an improved finned tube tooth forming device. Background Technology

[0002] Heat exchanger tubes based on enhanced heat transfer design are called high-efficiency heat transfer tubes, also known as finned tubes. Existing finned tube tooth forming machine structures, such as CN109759648A (a novel finned tube tooth forming equipment), reduce tool vibration during the processing of tube materials into finned tubes, avoiding damage to the finned tube thread walls and the occurrence of vibration marks, thus improving product quality to a certain extent.

[0003] However, in equipment such as the finned tube forming machine, when processing spiral fins on the outer side of the tube material, it is necessary to adjust the axial direction and spiral angle of multiple cutters arranged around the outer circumference of the tube material. This cutter adjustment operation requires professional personnel to continuously adjust each cutter. The operation is complex and tedious, time-consuming and labor-intensive, and highly dependent on the experience of the operators. Under normal circumstances, it takes 1-2 hours for an experienced operator to adjust all the cutters of a machine. For some ordinary operators, it may take half a day to adjust and they may not be able to use it normally, which seriously affects the use of the equipment and the production efficiency of the products.

[0004] Therefore, it is imperative for those skilled in the art to improve the finned tube tooth forming equipment in order to increase the tool setting speed of the device. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the combination or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0030] like Figure 1-6An improved finned tube tooth forming apparatus according to an embodiment is provided, comprising: a worktable 1, a housing 2, a base 3 disposed on the worktable 1, a plurality of tool assemblies 5 disposed on the base 3, a control assembly 4 disposed on the housing 2 and electrically connected to the plurality of tool assemblies 5, and a tube output mechanism 6 disposed on one side of the housing 2; the base 3 is a one-piece metal cavity structure, and multiple threaded holes for fixing the tool assemblies 5 are provided on both side walls; the plurality of tool assemblies 5 are symmetrically distributed on the base 3, and their bottoms are placed on the outer side wall of the tube located at the center of the base 3; the tool assembly 5 includes: a radial feed mechanism 51 fixed on the base 3, and a control assembly 51 suspended on the radial feed mechanism 52. Below the feed mechanism 51 are the cutting mechanism 52 and the adjustment mechanism. The adjustment mechanism includes: an angle adjustment mechanism 53 disposed between the radial feed mechanism 51 and the cutting mechanism 52, and an axial adjustment mechanism 54 disposed on the cutting mechanism 52. A base 3 on the worktable 1 is fixedly provided with a centrally symmetrical and evenly distributed array of multiple tool assemblies 5. The tool assemblies 5 can be configured in 3, 4 or more groups as needed. The tool assemblies 5 perform circumferential top-forming processing on the tube material located at the center of the base 3, ensuring that the tube material is subjected to balanced forces during processing and that the processing is stable and reliable. To improve the overall structural support strength, the base 3 is designed as a one-piece metal cavity structure. A control component 4, electrically connected to multiple tool assemblies 5, provides visual control over the feed of these assemblies. This allows ordinary technicians to quickly adjust the tools, making the operation convenient, quick, and time-saving. It eliminates the need for repeated measurements and adjustments, reducing reliance on operator experience and skill, while also improving the accuracy and efficiency of tool adjustment. The control component 4 controls and drives the cutting mechanism 52, suspended below the radial feed mechanism 51, to perform radial feed, bringing the tool into contact with the tube. An angle adjustment mechanism 53 is installed between the radial feed mechanism 51 and the cutting mechanism 52, and an angle adjustment mechanism 53 is also installed on the cutting mechanism 52. The adjustment mechanism 54, which is set on the upper part and electrically connected to the control component 4, adjusts the axial machining position and tilt angle of the cutting tool relative to the tube. It can accurately display and control the axial machining position and tilt angle of each tool relative to the tube. It is convenient to adjust to the target position for positioning and fixing in a timely manner, so as to ensure the adjustment accuracy. At the same time, it saves the time of repeated measurement and adjustment during the adjustment process, improving work efficiency. The operator can store the preset tool coordinates for operation and adjustment. The operation and adjustment can be completed quickly without relying too much on the operator's operating experience and proficiency, thereby improving production efficiency and the overall utilization rate of the equipment.

[0031] Specifically: such as Figure 3-6As shown, the radial feed mechanism 51 includes: a feed motor 511, a motor base 512, a motor base plate 513, connecting side plates 514 symmetrically arranged at the lower end of the motor base plate 513, a slide plate 516 connected between the two connecting side plates 514 by a slide rail 515, and a lead screw 157 and a transmission nut 518 connecting the slide plate 516 and the feed motor 511; the transmission nut 518 is fixed on the top of the slide plate 516, and the slide plate 516 is a periphery-closed cavity structure. 8 One end is built inside; the bottom of the cavity structure of the slide plate seat 516 is fixedly connected to the angle adjustment mechanism 53, and the bottom end of the angle adjustment mechanism 53 is rotatably connected to the cutting mechanism 52; the connecting side plate 514 is fixedly connected to the side wall of the base 3; the motor seat 512 and the motor seat plate 513 are provided with mounting through holes adapted to the lead screw 157; one end of the lead screw 157 is connected to the output end of the feed motor 511; the feed motor 511 drives the slide plate seat 516 and the cutting mechanism 52 connected below to feed radially relative to the tube material through the lead screw 157;

[0032] The cutting mechanism 52 includes: a rotating disk 521 disposed at the bottom of the rotating connecting seat 531 provided in the angle adjustment mechanism 53; a bottom pressure plate 522 fixed at the bottom of the rotating disk 521; a spindle transmission box 524 and a spindle motor 523 disposed on one side of the rotating disk 521 via a spindle box connecting plate 525; a spindle 526 suspended at the bottom of the spindle box connecting plate 525; a cutting tool 527; a spindle support 528; and a spindle box 529. The spindle 526 is fixed at the middle position of the bottom of the spindle box connecting plate 525 via the coaxially disposed spindle support 528 and spindle box 529. The bottom pressure plates 522 are spaced apart on both sides of the spindle support 528 and spindle box 529. The cutting tool 527 is sleeved on the spindle 526 between the spindle support 528 and spindle box 529. One end of the spindle 526 is connected to the spindle transmission box 524 for transmission.

[0033] The axial adjustment mechanism 54 includes: a spindle box connecting plate 525, a slide rail groove 541 adapted to the spindle box connecting plate 525 and disposed between the bottom of the rotating disk 521 and the bottom pressure plate 522, and an axial guide rail adjusting block 542 embedded in the other end of the slide rail groove 541 and abutting against the end of the spindle box connecting plate 525. The spindle box connecting plate 525 is placed in the slide rail groove 541 and slides left and right to adjust the axial processing position of the cutting tool relative to the tube. The axial guide rail adjusting block 542 embedded in the other end quantitatively controls the amount of sliding of the spindle box connecting plate 525 relative to the slide rail groove 541 and plays a limiting role for the spindle box connecting plate 525 placed in the slide rail groove 541.

[0034] The angle adjustment mechanism 53 includes: a rotating connecting seat 531, an angle positioning block 532 disposed on one side of the rotating connecting seat 531, an angle adjustment plate 533 disposed between the rotating connecting seat 531 and the angle positioning block 532, and an angle measuring sensor 534 disposed between the rotating connecting seat 531 and the cutting mechanism 52; the top of the rotating connecting seat 531 is fastened to the bottom of the radial feed mechanism 51 by bolts, and the bottom of the rotating connecting seat 531 is provided with an annular flange 5311, on which a plurality of concentric long arc-shaped adjustment holes 5312 and the cutting mechanism 52 are opened. The rotating disk 521 at the top can be rotated relative to the rotating disk 521 by bolts and then fastened. The target angle is determined by the expected helical angle of the pipe. The arc length of the long arc-shaped adjustment hole 5312 corresponds to the extreme rotation position of the rotating connection seat 531 and the rotating disk 521. The annular flange 5311 has symmetrical L-shaped right-angle limiting grooves 5313 on both sides. An angle positioning block 532 and an angle adjusting plate 533 are installed in the L-shaped right-angle limiting groove 5313 for matching and positioning. The angle positioning block 532 is fixed to the rotating disk 521 by bolts, and its top is perpendicular to one side of the L-shaped right-angle limiting groove 5313. The gap angle between the angle positioning block 532 and the other right-angle side of the L-shaped right-angle limiting groove 5313 is adjusted by setting different angle adjustment plates 533 to limit the rotation angle; the angle positioning block 532 and the rotation angle measuring sensor 534 are correspondingly set in the other L-shaped right-angle limiting groove 5313; by calling the angle positioning block 532 at different angles, the rotating disk 521 is rotated relative to the annular flange 5311 by a target angle and positioned in one side of the L-shaped right-angle limiting groove 5313, and the rotation angle measuring sensor 534 in the other side of the L-shaped right-angle limiting groove 5313 displays the corresponding rotation angle through the control component 4. For angle adjustment, loosen the bolts in the long arc-shaped adjustment hole 5312, and rotate the cutting mechanism 52 located below the rotating connecting seat 531. The control component 4 displays the corresponding rotation angle measured by the angle measuring sensor 534, or the set angle adjustment plate 533 is placed in the corresponding L-shaped right-angle limiting groove 5313 for target angle adjustment, and then the bolts are tightened to fix it. When using the angle measuring sensor 534 for angle adjustment, the angle adjustment plate 533 can be placed or not in the L-shaped right-angle limiting groove 5313 on the other side, thus completing the angle adjustment of the cutter relative to the tube. Adjusting the angle adjustment plate 533 can calibrate the angle measuring sensor 534, and can also be adjusted after the angle measuring sensor 534 is damaged, without affecting equipment operation and improving equipment utilization.

[0035] An alternative implementation: such as Figure 5-6As shown, the annular flange 5311 has a central through hole at its center. The angle adjustment mechanism 53 also includes a rotating shaft 536 coaxially positioned at the center of the rotating connecting seat 531 and the rotating disk 521. One end of the rotating shaft 536 is fixedly connected to the rotating disk 521, and the two are in a static fit of hole and shaft, which can be an interference fit, transition fit, keyway, spline, pin stop, etc. The rotating shaft 536 also has a boss 5361 coaxially positioned to fit the stepped hole 5314 in the rotating connecting seat 531. The other end of the rotating shaft 536 is rotatably connected above the stepped hole 5314 through a bearing 538 and a fastener 537. The rotating shaft 536 at the center of the rotating connecting seat 531 and the rotating disk 521 ensures a firm connection, smooth rotation, and accurate angle adjustment.

[0036] An alternative implementation: such as Figure 6 As shown, the outer cylindrical surface of the boss portion 5361 is also provided with multiple limiting grooves 5362. The side of the rotating connecting seat 531 is provided with limiting connecting holes 5315 corresponding to the limiting grooves 5362. A limiting structure 5316 is provided in the limiting connecting hole 5315, and one end of the limiting structure 5316 protrudes outward from the limiting groove 5362. An angle measuring sensor 534 is provided between the limiting structure 5316 and the limiting groove 5362 and is electrically connected to the control component 4. The arc length of the limiting groove 5362 corresponds to the limit position of the angle adjustment. The setting of the limiting structure 5316 and the limiting groove 5362 can ensure accurate angle adjustment and reliable limiting.

[0037] An alternative implementation: such as Figure 3-5 As shown, the top of the rotating connecting seat 531 is also provided with a rotating shaft 536 adapted to a corresponding rotation angle measuring sensor 534. The rotation angle measuring sensor 534 is set on the top of the rotating connecting seat 531 through a sensor bracket 535 and is built into the cavity structure of the slide plate seat 516.

[0038] An alternative implementation: such as Figure 3-5As shown, the axial adjustment mechanism 54 also includes an axial distance sensor 543 disposed between the spindle drive box 524 and the rotating disk 521. The axial distance sensor 543 is electrically connected to the control component 4. By setting the axial distance sensor 543 between the spindle drive box 524 and the rotating disk 521 to allow the spindle box connecting plate 525 to move axially relative to the slide rail groove 541, the original position of the spindle box connecting plate 525 is preset, thus determining the original position of the tool. The axial movement distance of the spindle box connecting plate 525 relative to the slide rail groove 541 can be measured by the axial distance sensor 543 and displayed on the control screen of the control component 4. Alternatively, it can be adjusted by the axial guide rail adjustment block 542 disposed at the other end of the slide rail groove 541 and abutting against the end of the spindle box connecting plate 525. Adjustment can be made quickly using the axial distance sensor 543, or the axial guide rail adjustment block 542 and the axial distance sensor 543 can be used simultaneously. Adjustment can also be made after the axial distance sensor 543 is damaged without affecting the operation of the equipment, thus improving the utilization rate of the equipment.

[0039] An alternative implementation: such as Figure 3-5 As shown, the spindle drive box 524 is equipped with gear transmission. The base 3 is a one-piece molded hollow structure, and multiple threaded holes on both sides of the base 3 are adapted to the connecting side plate 514. The spindle drive box 524 is equipped with gear transmission to avoid the insufficient power of the existing belt drive spindle box, which affects the cutting effect; the cutting torque can be increased by increasing the transmission ratio through gear transmission, avoiding the interference of the drive structure caused by the increase in cutting torque in the existing belt structure.

[0040] Additionally, this utility model can install a drive feedback structure electrically connected to the control component 4 on the angle adjustment mechanism 53 and the axial adjustment mechanism 54, thereby realizing automated adjustment and control of the tool in all directions, thus improving the intelligence of the equipment.

[0041] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
