[0057] To enable those skilled in the art to better understand the solution of this application, the following further detailed description of this application will be given in conjunction with the accompanying drawings and specific implementation manners.

[0058] Please refer to Figure 1-2 , Figure 1 , which is a schematic diagram of the processing equipment in the embodiment of this application; Figure 2 is Figure 1 a three - dimensional structure schematic diagram of the pre - processing hob assembly in

[0059] The processing equipment in this embodiment includes a material rack 100, a hob device 300, and a stamping device 700 arranged in sequence. A driving motor 101 and a coil 102 are provided on the material rack 100. A tape to be rolled is wound on the coil 102. Here, the tape that has not been processed is defined as the initial tape 200. The driving motor 101 drives the initial tape 200 to move towards the hob device 300. After being rolled and formed in the hob device 300, it then enters the stamping device 700 for stamping and cutting, and finally forms the required workpiece 203. The structure that the workpiece 203 needs to be formed is defined as the first structure 2031. In this embodiment, the workpiece 203 is specifically a fin with a window, so the first structure 2031 includes multiple rows of fin peaks in the fin, that is, the first structure 2031 includes Figure 25 the multiple rows of protrusions 2031a shown in

[0060] The following is a detailed description of the hob device 300. The hob device 300 is as shown in Figure 2 , and includes three groups of hob assemblies, namely a pre - processing hob assembly 1A, a first hob assembly 2A, and a second hob assembly 3A.

[0061] As shown in Figure 3-10 , Figure 3 is Figure 2 a schematic diagram of the pre - processing hob assembly 1A in Figure 4 is Figure 2 a schematic diagram of a first hob 1 in Figure 5 is Figure 4 an enlarged view of part A in Figure 6 is Figure 4Left view of the first hob 1; Figure 7 is Figure 4 Top view of the first hob 1 in Figure 8 is Figure 4 Schematic diagram of the three-dimensional structure of the first hob 1 in Figure 9 is Figure 8 Enlarged view of part B in Figure 10 is Figure 8 Partial three-dimensional schematic diagram of the first hob 1 in

[0062] The preprocessing hob assembly 1A in this embodiment includes two meshing first hobs 1, which are arranged vertically. The first hob 1 is gear-shaped, and a circle of preprocessing teeth 11 is provided on its outer periphery, which is arranged circumferentially. The preprocessing teeth 11 are serrated. As Figure 5 shown, the cross-section of the preprocessing teeth 11 in the radial plane of the first hob 1 is approximately V-shaped, and the preprocessing teeth 11 extend along the axial direction of the first hob 1, specifically from one end of the axial direction of the first hob 1 to the other end of the axial direction.

[0063] As Figure 3 shown, the two first hobs 1 of the preprocessing hob assembly 1A are arranged up and down relatively. The initial strip 200 to be rolled can be fed between the two first hobs 1 along the conveying direction. Under the action of the relative rotation and meshing of the two first hobs 1, the initial strip 200 to be rolled will be rolled into Figure 3 the corrugated strip 201 shown, and the corrugated strip 201 will continue to be conveyed to the first hob assembly 2A downstream.

[0064] As Figure 5 shown, the preprocessing teeth 11 of the first hob 1 are V-shaped. The cutting edge surface of the preprocessing teeth 11 includes a first cutting edge surface 111 and a second cutting edge surface 112, which are the two sides of the V shape. The first cutting edge surface 111 and the second cutting edge surface 112 are symmetrically arranged with respect to the axis of the first hob 1. The processed corrugated strip 201 includes continuous V-shaped protrusions. The width (the distance L between adjacent preprocessing teeth 11) and height H of the preprocessing teeth 11 will affect the size of the first structure 2031 of the workpiece 203 processed in the subsequent process. Therefore, the width L and height H of the preprocessing teeth 11 can be specifically determined according to the workpiece 203 to be processed. When the workpiece 203 is a fin, the height H of the preprocessing teeth 11 is equal to the height of the wave crest of the processed corrugated strip 201 and the height of the fin crest. When rolling is performed in the following process, the height of the teeth (the first tooth 211, the second tooth 311) of the hob is also equal to the height of the fin crest.

[0065] As Figure 11-23 shown, Figure 11 is a schematic diagram of the first hob assembly 2A; Figure 12 is Figure 11Enlarged view of part C; Figure 13 is Figure 11 Schematic perspective view of the first hob assembly 2A in

[0067] The first hob assembly 2A in this embodiment includes two meshing first hobs 2, and the two first hobs 2 are arranged one above the other. The first hob 2 is generally gear-shaped, and its outer periphery is provided with multiple circles of first tooth portions 211 distributed along the axial direction. The first tooth portions 211 are different from Figure 8 the longer pre-machined tooth portions 11 of the first hob 1 in that extend axially to both ends. The length of the first tooth portions 211 of the first hob 2 in this embodiment along the axial direction is smaller. The outer periphery of the first hob 2 is provided with multiple circles of first tooth portions 211 distributed along the axial direction, as shown in Figure 14 、 15 As shown, two adjacent circles of first tooth portions 211 in the axial direction are staggered in the circumferential direction, that is, in the axial projection, a first tooth portion 211 of one circle and a first tooth portion 211 of an adjacent circle do not coincide, but partially coincide.

[0068] In order to facilitate the formation of multiple circles of staggered first tooth portions 211, the first hob 2 in this embodiment may include multiple first blades 21. Each first blade 21 is provided with a circle of first tooth portions 211 on its outer periphery. Then the first hob 2 may include multiple first blades 21 stacked axially. When one first blade 21 is worn, the worn first blade 21 can be replaced.

[0069] Such as Figure 18 、 20, as shown in Fig. 21, the first tooth part 211 is specifically trapezoidal, that is, in the radial cross-section of the first blade 21, the cross-section of the first tooth part 211 is trapezoidal. The top 2111 of the first tooth part 211 is the top surface of the blade edge. The root of the first tooth part 211 is integrally connected to the first hob 2 or the body of the first blade 21. The blade surface of the first tooth part 211 further includes a first side part 2112 and a second side part 2113 connecting the top 2111 and the root. Both the first side part 2112 and the second side part 2113 are inclined planes. The edge where the side part meets the top 2111 is the blade edge. In this embodiment, the edge between the first side part 2112 and the top 2111 can be set as the blade edge, and the edge between the second side part 2113 and the top 2111 can also be set as the blade edge, that is, the first tooth part 211 has a double-sided blade structure. In this way, the first hob 2 can be used in both forward and reverse directions. When one side is worn out, the first hob 2 is mirror-inverted to switch to the other side for use, thereby extending the service life of the first hob 2. It can be seen that when the first hob 2 is assembled by multiple first blades 21, if one or more first blades 21 are worn, the worn blades can be mirror-inverted without replacing the entire position of the first hob 2.

[0070] As Figure 13 , 16 shown, the first hob 2 in this embodiment further includes corner pieces 22. Multiple first blades 21 are stacked axially to form a blade assembly. One corner piece 22 is provided at one end of the blade assembly along the axis, and another corner piece 22 is provided at the other end. The corner pieces 22 and the first blades 21 are coaxially arranged. The corner pieces 22 are provided to squeeze and assemble multiple first blades 21 together to prevent the first blades 21 from loosening. The outer periphery of the corner pieces 22 also has a circle of tooth parts, defined as the fourth tooth part 221. The fourth tooth part 221 axially abuts at least part of the first tooth part 211. As Figure 14 shown, the axial length D of the fourth tooth part 221 (i.e., the thickness of the fourth tooth part 221) is thicker than the thickness of the first tooth part 211, for example, twice the thickness of the first tooth part 211. In this way, the first tooth part 211 has sufficient strength, which is beneficial for clamping the strip to be rolled and fixing the first blade 21 to prevent the blade edge of the first blade 21 from being laterally deformed. An end cap 24 can also be provided on the outer side of the corner piece 22 along the axis. The end cap 24, the corner piece 22, and the first blade 21 can be fastened and stacked together by bolts.

[0071] When Figure 3 the corrugated strip 201 pre-formed by the pre-processing hob assembly 1A enters between the two first hobs 2, after the two first hobs 2 rotate and mesh relative to each other, the corrugated strip 201 will be further processed to form as Figure 11The first formed strip 202 with a trapezoidal intersection of the shown shape, the first formed strip 202 processes the first structure 2031 required for the workpiece 203, that is, directly forms the first structure 2031, or the first formed strip 202 has at least a part of the first structure 2031, and can be shaped and reprocessed through subsequent processes to form a complete first structure 2031.

[0072] Can be combined Figure 24-25 Understood, Figure 24 For the Figure 1 Partial schematic diagram of the workpiece 203 formed after stamping and cutting by the stamping device 700 in the figure. At the same time, only a partial first structure 2031 of the workpiece 203 is also shown. In fact, the main body of the workpiece 203 is basically the first structure 2031. The first structure 2031 is a multi-column windowed fin peak, and the first hob assembly 2A can also be called a windowed hob assembly; Figure 25 Is Figure 24 Schematic diagram of the H part in the figure.

[0073] From Figure 24 、 25It can be seen that the first structure 2031 of the workpiece 203 corresponds to the first tooth part 211 of the first hob 2, and the structural form of the first tooth part 211 is set according to the first structure 2031 of the workpiece 203. The first structure 2031 includes a plurality of rolling structure units 2031c, and each rolling structure unit 2031c includes a plurality of protrusions 2031a. There is a connecting wall part 2031b between adjacent protrusions 2031a. That is, each rolling structure unit 2031c is a continuous protrusion arrangement, that is, it includes a plurality of protrusions 2031a arranged in a straight line. One protrusion 2031a is a fin peak of a fin in this embodiment. The plurality of rolling structure units 2031c are arranged in a predetermined direction. Projecting along the predetermined direction, a part of a protrusion 2031a of one rolling structure unit 2031c overlaps with a protrusion 2031a of an adjacent rolling structure unit 2031c. The cross-section of the protrusion 2031a in this embodiment is specifically trapezoidal, that is, the first tooth part 211 is the same as a protrusion 2031a in each rolling structure unit 2031c. There is a connecting wall part 2031b between two protrusions 2031a. The connecting wall part 2031b and the two side walls of the protrusion 2031a form a concave part. That is, each rolling structure unit 2031c is an alternating distribution of concave parts and protrusions 2031a. Correspondingly, between two adjacent first tooth parts 211 of the first hob 2 in the circumferential direction is an arc-shaped circumferential wall section 212 of the first blade 21. The arc-shaped circumferential wall section 212 and the two sides of the first blade 21 form a concave part. Then the arc-shaped circumferential wall section 212 of the first blade 21 corresponds to the connecting wall part 2031b of the first structure 2031. When there are other design requirements for the structural form of the first structure 2031 of the workpiece 203, the first tooth part 211 can be adjusted accordingly. For example, if the workpiece 203 includes rectangular protrusions 2031a, then the first tooth part 211 is no longer trapezoidal and is correspondingly set to be rectangular. The workpiece 203 is not limited to being a fin, and the formed first structure 2031 is not limited to being a fin peak. The first structure 2031 can be other structural forms including a plurality of protrusions.

[0074] In addition, in the above embodiment, the first tooth parts 211 of adjacent first blades 21 of the first hob 2 are staggered in the circumferential direction. In this way, the protrusions 2031a of adjacent two rolling structure units 2031c of the workpiece 203 formed by processing are also staggered in the circumferential direction, as Figure 25 shown, and the formed fins have multiple rows of staggered windowed fin peaks, which can meet the better heat dissipation performance requirements of the fins.

[0075] It should be understood that when the adjacent rolling structure units 2031c of the workpiece 203 do not need to be staggered, the first tooth parts 211 of adjacent first blades 21 do not need to be staggered either. The first hob 2 can also be provided with a pre-processing tooth part 11 that is axially continuous like the pre-processing hob 1. In short, the first tooth part 211 is designed according to the manufacturing requirements of the workpiece 203, and no further elaboration will be made here.

[0076] As shown Figure 21 in the figure, the distance L between two adjacent first tooth portions 211 of the first hob 2 and the height H of the first tooth portion 211 are equal to the distance L between two adjacent pre-machined tooth portions 11 of the pre-machined hob 1 and the height H of the pre-machined tooth portion 11, and are all set according to the forming requirements of the workpiece 203. Of course, the dimensions of the workpiece 203 will also consider the limitations of the processing technology. By adjusting the distance L and the height H, the height and width of the protrusion 2031a of the workpiece 203 can be adjusted, specifically, the height and width of the fin peak of the fin are adjusted. For this embodiment, the distance L and the height H satisfy the relational expression: L / H ≤ 1.3. Such a dimension setting makes it easy to control the deformation amount and the pulling force during the rolling deformation. The thickness tolerance of the first blade 21 and the first blade 31 can be limited to ±0.002 mm, and the parallelism is limited within 0.002 mm.

[0077] In this embodiment, a pre-machined hob assembly 1A is further provided upstream of the first hob assembly 2A for performing forming rolling by the processing equipment. After the initial strip 200 to be rolled is first processed into a corrugated strip 201, it is then sent into the first hob assembly 2A for rolling forming. Processing the corrugated strip 201 is a bending deformation with a relatively small deformation amount, and it is not easy to be pulled too much to damage the initial strip 200. Therefore, the initial strip 200 can be integrally rolled, that is, the entire area processed into the first structure 2031 is rolled simultaneously. The first hob assembly 2A is used to form at least a part of the first structure 2031 of the workpiece 203. The first structure 2031 is more complex than a relatively simple bending structure. For example, the trapezoidal protrusion 2031a in this embodiment is also connected by a connecting wall portion 2031b between adjacent protrusions 2031a. If a flat strip is integrally stamped, the deformation amount will be too large, and the pulling force on the strip will also be too large, and it is easy to be damaged by rolling. Therefore, the first structure 2031 cannot be directly integrally rolled and formed by the first hob assembly 2A. In this embodiment, due to the provision of the pre-machined hob assembly 1A in front, the initial strip 200 can be pre-processed into a corrugated strip 201 according to the size of the protrusion 2031a of the first structure 2031, that is, the V-shaped height of the processed corrugated strip 201 is the height of the protrusion 2031a of the workpiece 203, and the V-shaped width is the width of the protrusion 2031a. Then, it is further subjected to rolling processing by the corresponding first hob assembly 2A for forming the first structure 2031. The rolling processing pulls and deforms the V-shaped structure of the corrugated strip 201 to form the required protrusion 2031a. It can be seen that the forming of the first structure 2031 is carried out in two steps, and the deformation amount is released twice, thereby enabling the integral processing of the strip, improving the work efficiency, and not damaging the strip.

[0078] It should be noted that although the corrugated strip 201 can obtain the required protrusions 2031a after being processed by the first hob assembly 2A, a second hob assembly 3A is also provided in this embodiment. As Figure 26 shown, Figure 26 FIG. is a schematic diagram of the second hob assembly 3A in an embodiment of the present application. The second hob assembly 3A has the same structure as the first hob assembly 2A. The second hob assembly 3A includes two meshing second hobs 3. Each second hob 3 includes a plurality of second blades 31 stacked axially. A second tooth portion 311 is provided on the outer periphery of the second blade 31. Hanging corner pieces and end covers are also provided at both ends of the second hob 3.

[0079] The second hob assembly 3A is arranged downstream of the first hob assembly 2A. The initial strip 200 to be rolled is first rolled into a corrugated strip 201 by the pre-processing hob assembly 1A, then into a first formed strip 202 by the first hob assembly 2A, and then conveyed to the second hob assembly 3A. The second hob assembly 3A further processes and shapes it to ensure that the required protrusions 2031a are processed, reducing product defects caused by possible incomplete local rolling of the second rolling assembly 2A. It can be seen that the second hob 3 of the second hob assembly 3A and the first hob 2 of the first hob assembly 2A are axially aligned to ensure that the same position of the first formed strip 202 after being rolled by the first hob assembly 2A will undergo the same rolling process after passing through the second hob assembly 3A, and a second formed strip 204 is formed after being rolled by the second hob assembly 3A. In this embodiment, the workpiece 203 for processing is a fin, then the first hob assembly 2A can be called the initial windowing hob assembly, and the second hob assembly 3A can be called the secondary windowing hob assembly. The two processes are initial windowing and secondary windowing respectively.

[0080] In addition, the provided second hob assembly 3A is not only beneficial for further shaping the first formed strip 202, but also facilitates the setting of the stripping piece 733.

[0081] As Figure 27 、 28 shown, Figure 27 FIG. is a schematic diagram of the cooperation between the first hob assembly 2A and the stripping piece assembly 73; Figure 28 is Figure 27 top view.

[0082] The stripping piece assembly 73 includes a first-layer stripping piece 731 and a second-layer stripping piece 732. Each layer includes a plurality of stripping pieces 733. The stripping pieces 733 can be metal sheets. The stripping pieces 733 have good toughness and a Rockwell hardness that can reach 58-62. The two layers of stripping pieces 733 are distributed up and down. Taking the tangent line passing through the meshing positions of the two first hobs 2 and tangent to the first hob 2 as the reference line X, the two layers of stripping pieces 733 are located on both sides of the reference line X. At Figure 27Among them, that is, on the upper and lower sides of the reference line X, the meshing position is a recess where a first tooth portion 211 is inserted between two second tooth portions 211 of another first hob 21. At this time, the reference line X passes through the middle part between the root of the first tooth portion 211 and the recess. The upper first stripping piece 731 is close to the upper first hob 2, the lower second stripping piece 732 is close to the lower first hob 2, and the stripping piece 733 is at a predetermined distance from the meshing position of the two first hobs 21, that is, as close as possible to the meshing position, but without interfering with the rotation of the first hob 2. In this way, when the processed first formed strip 202 is pushed out between the two first hobs 2, it can be located between the first stripping piece 731 and the second stripping piece 732, facilitating the separation of the processed first formed strip 202 from the first hob assembly 2A and avoiding affecting the conveyance of the first formed strip 202 along the production line.

[0083] Furthermore, in combination with Figure 15 、 21 、22, and continue to refer to Figure 29 for understanding, Figure 29 FIG. is a comparison schematic diagram of the second hob assembly 3A and the first hob assembly 2A.

[0084] In this embodiment, the first hob 2 further includes a third blade 23. The outer periphery of the third blade 23 is a plane and does not have the first tooth portion 211. The outer peripheral wall of the third blade 23 is flush with the root of the first blade 21. The third blade 23 and a plurality of first blades 21 are stacked axially together. One third blade 23 is located between two adjacent first blades 21. In this way, at the position where the third blade 23 is located, an annular flat belt b will be formed on the outer periphery of the first hob 2. The annular flat belt b is the annular outer peripheral wall of the third blade 23, and an annular gap a can be formed between the two first blades 21. Looking again at Figure 27 , at this time, the second stripping piece 732 of the stripping piece assembly 73 can be closer to the lower first hob 2. One end of the stripping piece 733 in the second stripping piece 732 close to the first hob assembly 2A can be set to have an arc surface 7331 slanting downward. The arc surface 7331 generally matches the outer periphery of the first hob 2. In this way, one end of the second stripping piece 731 provided with the arc surface 7331 can extend into the annular gap a, that is, be embedded into the annular gap a without contacting the third blade 23 and without interfering with the rotation of the first hob 2. Similarly, one end of the stripping piece 733 in the first stripping piece 731 can be provided with an arc surface slanting upward and can be embedded into the annular gap a of the upper first hob 2 to be closer to the upper first hob 2. With such a setting, the stripping piece assembly 73 can be further close to the meshing position of the two first hobs 2 of the first hob assembly 2A, thus being more conducive to the separation of the first formed strip 202.

[0085] As Figure 27 、28 As shown, each layer of the stripping piece assembly 73 may include a plurality of stripping pieces 733. The number of the first-layer stripping pieces 731 and the second-layer stripping pieces 732 is equal. In this embodiment, four stripping pieces 733 are specifically arranged in each layer. Correspondingly, each first hob 2 is provided with four annular gaps a distributed along the axial direction, so that stripping can be realized relatively evenly. Of course, the number of the stripping pieces 733 in each layer is not limited, and three or more than three can be set. Specifically, it is designed according to the axial length of the hob. The fewer the number of the stripping pieces 733 within the available range, the better, so as to reduce the setting of the annular gaps a.

[0086] The plurality of stripping pieces 733 in each layer can be fixed by a fixed shaft 75. As Figure 27 、 28 shown, the first-layer stripping pieces 731 are fixed by two fixed shafts 75, and the second-layer stripping pieces 732 are also fixed by two fixed shafts 75, so that the stripping pieces 733 in each layer can be reliably fixed together. Reinforcing rings 74 made of metal are further arranged on both axial sides of each layer of stripping pieces 733 to strengthen the fixing of the stripping pieces 733 in one layer. The first-layer stripping pieces 731 and the second-layer stripping pieces 732 are finally fixed together by a locking screw 72. Specifically, the locking screw 72 can combine a gasket 76 to fix the two layers of stripping pieces 733 to the workbench 01 of the processing equipment (shown in Figure 2 ). In addition, as Figure 28 shown, two guide blocks 71 distributed along the axial direction are schematically shown. The guide blocks 71 can position the first-layer stripping pieces 731 and the second-layer stripping pieces 732 along the axial direction of the hob to prevent the stripping pieces 733 from being misaligned.

[0087] Specifically, when installing the stripping pieces 733, the stripping pieces 733 should be as close as possible to the meshing position of the two first hobs 2. When setting the annular gaps a, the ends of the stripping pieces 733 can be embedded in the annular gaps a, so that the distance from the meshing position is further shortened. Figure 27Among them, the upper and lower stripping pieces 733 are aligned one by one in the vertical direction. (The upper and lower stripping pieces 733 are respectively aligned at the same layer height, and both ends of the upper and lower stripping pieces 733 are aligned.) The upper stripping piece 733 is as close as possible to the tooth top of the lowermost first tooth part 211 of the upper first hob 2, and the lower stripping piece 733 is as close as possible to the tooth top of the uppermost first tooth part 211 of the lower first hob 2. The distance from the tooth top is the predetermined distance. Specifically, the predetermined distance d1 between the upper and lower stripping pieces 733 and the tooth tops of the corresponding first tooth parts 211 can be 1 mm to 3 mm, for example, 1.5 mm, which will neither interfere with the rotation of the first hob 2 nor be close to the meshing position, so that the first formed strip 201 after rolling processing at the meshing position can be stripped as soon as possible. In this embodiment, the length L1 of the strip 733 is approximately 120 mm to 180 mm, and the height h1 of the stripping piece 733 can be approximately set to 1 / 2 of the radius of the first hob 2. In addition, after the stripping piece 733 is inserted into the annular gap a, the distance from the annular flat belt b is less than the height of the fin peak formed by the window opening. The height of the fin peak is the height of the first tooth part 211, so that the first formed strip 201 cannot continue to wind around the first hob 2 and can be smoothly stripped.

[0088] It can be understood that the second hob assembly 3A is also set in the same way, that is, an annular gap a is set. Then, the stripping piece assembly 73 downstream of the second hob assembly 3A can also be closer to the position where the two second hobs 3 are meshed, which is beneficial to the stripping of the second formed strip 204. The principle will not be repeated. The second hob 3 can be provided with a fourth blade 33, which is sandwiched between the two second blades 31 to form an annular gap a. It can be seen that a stripping piece assembly can also be provided downstream of the preprocessing hob assembly 1A. However, the first hob 1 of the preprocessing hob assembly 1A is a bent hob, and it is relatively easy to strip the corrugated strip 201. Therefore, the preprocessing hob assembly 1A can not be provided with an annular gap, and the stripping piece does not need to be provided with an arc surface. The first hob 11 is a bent hob, which has strong wear resistance and low precision requirements, and can work for a long time without replacement.

[0089] It is worth mentioning that in this embodiment, the annular gap a of the second hob assembly 3A and the annular gap a of the first hob assembly 2A are staggeredly arranged in the axial direction of the first hob assembly 2A and the second hob assembly 3A, as Figure 29As shown, when the corrugated strip 201 passes through the first hob assembly 2A, due to the setting of the annular gap a, the part of the corrugated strip 201 corresponding to the annular gap a will not be roll - processed. That is, the first structure 2031 on the first formed strip 202 is not fully processed (only multiple 2031a are formed). When passing through the second hob assembly 3A, this position no longer corresponds to the annular gap a, but will be supplemented and roll - pressed by the second tooth part 311 of the second hob assembly 3A, so as to ensure that the whole is processed, and the first structure 2031 is processed on the formed second strip 204. It can be seen that the second hob assembly 3A and the first hob assembly 2A are generally the same in structure, except that the axial position of the annular gap a is different.

[0090] Please continue to refer to Figure 2 , the hob device 300 in this embodiment includes three groups of hob assemblies, and the components configured for each group of hob assemblies are the same. Figure 2 Taking the pre - processing hob assembly 1A as an example for illustration, each group of hob assemblies includes a material guiding groove 06, a workbench 01, and a transmission gear 02. The first hob 1, the first hob 2, and the second hob 3 of the three hob assemblies are respectively supported on the workbench 01 through corresponding connecting shafts 08. The transmission gear 02 can transmit the power of the motor corresponding to the hob to the connecting shaft 08. As Figure 1 shown, the first motor 4, the second motor 5, and the third motor 6 are respectively arranged for the three groups of hob assemblies, so as to drive the corresponding hobs to rotate. The hobs and the transmission gear 02 are connected to the workbench 01 through the corresponding connecting shafts 08, that is, they are connected to the workbench 01 in a detachable connection manner. Then, the hobs can be replaced according to the processing requirements, for example, replacing hobs of different specifications, so that a set of equipment can be used to process products of different specifications.

[0091] The upper surface of the material guiding groove 06 is provided with a crawler belt, which can send the strip (the initial strip 200, or the corrugated strip 201, or the first formed strip 202) into the corresponding process at a uniform speed. A fixing part 05 is fixed below the material guiding groove 06. The fixing part 05 can fix the material guiding groove 06 horizontally and play a positioning role for the strip. The fixing part 05 can be connected to the corresponding workbench 01 through nuts, nuts, and adjusting screws 03. The adjusting screw 03 can adjust the horizontal position of the material guiding groove 06, where the horizontal direction is perpendicular to the conveying direction of the strip. The hobs of each hob assembly can be fixed on the connecting shaft 08 of the corresponding transmission gear 02 through hexagon socket head cap screws and locked by nuts.

[0092] As Figure 2 shown, each hob assembly is also provided with a hob limit block 04. The hob limit block 04 is arranged between the upper connecting shaft 08 and the lower connecting shaft 08 of the hob assembly, and is used to ensure that the center distance between the upper and lower hobs is fixed and limit the up - and - down movement of the hobs.

[0093] In addition, each hob assembly is also provided with a hob center distance adjusting block 9, and the hob center distance adjusting block 9 is arranged at both ends of the upper connecting shaft 08. The hob center distance adjusting block 9 is fixed on the workbench 01 by adjusting the limit screw 8, and the hob center distance adjusting block 9 is connected to the connecting shaft 08. By adjusting the limit screw 8 to adjust the height relative to the workbench 01, the height adjustment of the connecting shaft 08 can be realized, and then the adjustment of the center distance between the upper and lower hobs of each hob assembly can be realized. Finally, the tooth height of each turn of the hob is made consistent, and at the same time, the connecting shaft 08 is prevented from driving the hob to move horizontally.

[0094] In this embodiment, nozzle fixing blocks 07 are also arranged on the sides of the upper and lower connecting shafts 08 of each hob, which are used to fix the nozzles for lubricating the hob to provide lubricating oil for lubricating the hob. Lubrication is required during both the rolling and subsequent stamping processes.

[0095] The rolling processing method of the workpiece 203 provided in this embodiment can be referred to Figure 30 as shown in Figure 30 which is a flowchart of the rolling processing method in the embodiment of the present application, and includes the following steps:

[0096] Step S1: Feed the initial strip 200 to be rolled for processing the workpiece 203 into the pre-processing hob assembly 1A of the processing equipment, and the pre-processing hob assembly 1A bends and rolls the initial strip 200.

[0097] The pre-processing hob assembly 1A is the bending hob mentioned in the above embodiment, and the initial strip 200 to be rolled can be processed into a corrugated strip 201.

[0098] Step S2: Feed the corrugated strip 201 after being bent and rolled by the pre-processing hob assembly 1A into the first hob assembly 2A of the processing equipment.

[0099] The first hob assembly 2A is specifically the hob assembly mentioned in the above embodiment for rolling the strip into the first structure 2031 or at least part of the first structure 2031. The first hob assembly 2A is specifically the hob assembly with a trapezoidal first tooth part 211 mentioned in the above embodiment. After rolling, a first formed strip 202 is formed.

[0100] Specifically, in specific implementation, step S3 may also be included:

[0101] Feed the first formed strip 202 after being rolled by the first hob assembly 2A into the second hob assembly 3A.

[0102] The second hob assembly 3A is the same as the first hob assembly 2A, both performing rolling operations to further roll and shape the first formed strip 202 into a second formed strip 204.

[0103] Further, if there is a deviation between the outer shape of the second formed strip 204 after rolling and the finished appearance of the workpiece 203, a stamping device 700 can be provided. After step S3, step S4 is further included:

[0104] The second formed strip 204 rolled by the second hob assembly 3A is sent into the stamping device 700 for stamping and cutting to form the workpiece 203. The stamping device 700 specifically includes a machine tool, and the machine tool is provided with a stamping die 701 to cut the second formed strip 204 to form the workpiece 203.

[0105] Please combine Figure 1 Understand that before being sent into the stamping device 700, a buffer area 400 is provided. That is, the second formed strip 204 output from the second hob assembly 3A does not directly enter the stamping device 700, but first falls into the buffer area 400, and then is conveyed into the stamping device 700 by the buffer area 400. The feeding speed of the stamping device 700 and the feeding speed of the upstream hob device 300 do not necessarily need to be consistent. Therefore, the buffer area 400 is provided to separate the hob device 300 and the stamping device 700, which can avoid or reduce the influence of the speed difference on the normal operation of each station.

[0106] Continue to refer to Figure 1 Before entering the pre-processing hob assembly 1A, step S0 can also be included:

[0107] The initial strip 200 to be rolled is sent in and straightened, that is, the initial strip 200 is pulled flat.

[0108] The initial strip 200 comes from the coil 102, that is, it is wound on a cylindrical coil rack. If the initial strip 200 is directly input into the pre-processing hob assembly 1A, there may be problems such as coiling and difficult conveying. After straightening the initial strip 200 and then conveying it to the downstream process, it is beneficial to the smoothness of the conveying and ensures the smooth progress of the rolling process. Specifically, the device for straightening mainly includes a dancer wheel. The initial strip 200 enters the dancer wheel from the coil rack 100 to achieve the purpose of pulling and flattening. The straightened initial strip 200 can be sent to the guide groove 06 of the hob device 300 by a crawler for rolling operation.

[0109] In addition, between the above steps S1 and S2, between steps S2 and S3, and between steps S3 and S4, operations of peeling the processed strip through the stripping piece 733 are included. Look again Figure 1, the processing equipment further includes a strip flattening roller 500 and a wave wheel 600 disposed between the buffer area 400 and the stamping device 700. The strip flattening roller 500 can further flatten the second formed strip 204 and then feed it into the stamping device 700 for stamping and cutting. The wave wheel 600 serves the purpose of feeding the material downstream, and the number of teeth rotated by the wave wheel 600 determines the feeding speed. There is a deviation between the stamping speed of the stamping device 700 and the rolling forming speed of the upstream hob device 300. The rolling forming speed is slower. The wave wheel 600 can better balance the speed difference between the two processes and can also flatten the strip, so that the strip will not accumulate during stamping.

[0110] The embodiment of this application also has the following technical effects:

[0111] 1. For workpieces 203 such as fins, which have processing requirements for the first structure 2031 such as multiple rows of protrusions 2031a. According to the existing stamping and forming method, if the whole stamping of bending and piercing the sheet is carried out at one time, the pulling force on the sheet is too large and it is easy to be damaged. Therefore, only one row of protrusions can be processed by stamping at a time. If the number of rows is large, the processing efficiency is slow and there is a limit to improving the production capacity. In the method of this embodiment, the corrugated strip 201 is first processed as a whole. This kind of single bending processing has a small deformation amount, and even if processed as a whole, it will not generate too large a pulling force. Then, rolling processing is carried out, and the whole processing can be realized to improve the processing efficiency.

[0112] 2. According to the stamping and forming processing method in the background technology, there are relatively strict requirements for the feeding speed. The feeding cannot be too fast. If 0.01 mm more material is fed, it will result in a delay error of up to 0.30 - 0.50 mm after the fin is stamped and windowed, resulting in uneven arrangement of the fin peaks. Therefore, the overall processing speed is further limited, and feeding can only be carried out again after the stamping action of one row of fin peaks is completed. In this application, the processing of the strip is mainly rolling processing. The rolling processing has relatively loose requirements for the feeding speed, and the feeding speed can be optimized. The feeding port of the hob device 300 can feed quickly. Even if the feeding speed is too fast, it will not cause the strip to accumulate, nor will it affect the rolling forming effect of workpieces 203 such as fins, and the processing speed of the entire production line can be accelerated.

[0113] 3. In this embodiment, the rotation speed of the transmission gear 02 for rolling is controlled by the corresponding motor. The transmission gear 02 drives the corresponding hob to rotate and process through the connecting shaft 08. The motor can be adjusted according to the subsequent stamping and cutting speed, so that the production line does not stagnate and product accumulation and chaos are prevented; in addition, by adjusting the hob speed through the motor, the production speed can be increased relative to stamping and forming. In actual production, calculated according to the speed ratio of the motor, up to 220 workpieces 203 can be processed per minute at most. Compared with stamping processing, the efficiency can be increased by more than 10 times;

[0114] 4. Import the strip between the meshing hob cutters for bending and rolling forming. In this way, by setting the height, thickness of the tooth part of the hob cutter and the center distance between the upper and lower hob cutters, the height of the protrusion 2031a to be processed can be adjusted, and the adjustment is relatively convenient.

[0115] 5. In this embodiment, the three hob cutter assemblies are independent of each other and can be jogged, that is, only a single hob cutter assembly can work, or they can be linked, that is, the three hob cutter assemblies work together. In this way, the actions and speeds of each hob cutter assembly can be adjusted according to actual needs. When a certain hob cutter assembly needs to be replaced and adjusted, the other hob cutter assemblies can continue to work, reducing the impact on the efficiency of the entire production line. The strip between two adjacent hob cutter assemblies can be arc-shaped, that is, the length of the strip waiting for processing and located between the two hob cutter assemblies can be set to be greater than the track length of the material guiding groove 06 between two adjacent rolling processes, in an arched state, so as to leave room and prevent the situation that the strip is pulled due to uneven speed when the hob cutter rolls.

[0116] It should be noted that when processing the workpiece 203 above, in step S1, the initial strip 200 is bent and rolled by the pre-processing hob cutter assembly 1A to form a corrugated strip 201, that is, the pre-processing component 1' is set to process the corrugated strip 201. The pre-processing component 1' includes the pre-processing hob cutter assembly 1A, but the pre-processing component 1' is not limited to the pre-processing hob cutter assembly 1A and can also be a stamping component. Then, step S1 can also be carried out by stamping with the stamping component to process the corrugated strip 201. Since the deformation amount of processing the flat plate into the corrugated strip 201 is small, even if it is directly formed by integral stamping, the pulling force will not be too large to cause damage during stamping. However, as mentioned above, the efficiency and effect of stamping are lower than those of rolling, and there are more stringent restrictions on the feeding speed. Therefore, it is more efficient to adopt rolling processing as the pre-processing step S1.

[0117] In this article, specific examples are used to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
