Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of aluminum profile rolling, and particularly relates to a broken bridge thermal insulation aluminum profile rolling machine. BACKGROUND

[0002] In the processing technology of broken bridge thermal insulation aluminum profile, the vertical head on the outside of the upper notch of the lower profile and the vertical head on the outside of the lower notch of the upper profile after the threading are respectively rolled to the corresponding notch to make the thermal insulation strip firmly embedded in the corresponding upper notch and lower notch. Thus, various broken bridge thermal insulation aluminum profile rolling machines are born.

[0003] The existing broken bridge thermal insulation aluminum profile rolling machine comprises a rack and a rolling device and a profile conveying device arranged on the rack. The rolling device comprises a plurality of rolling units arranged in sequence, each rolling unit having a lower rolling wheel and an upper rolling wheel for rolling the vertical head of the lower profile and the vertical head of the upper profile, respectively. The profile conveying device comprises a plurality of profile conveying units corresponding to the plurality of rolling units, each profile conveying unit having a lower supporting roller and an upper pressing roller for supporting and pressing the lower side and the upper side of the aluminum profile, respectively. In order to ensure the smooth progress of the entire processing technology, the distance between the lower supporting roller and the contact surface of the lower side of the aluminum profile is set as the height of the machine table of the rolling machine, and the height of the machine table is always kept consistent with the height of the machine table of the threading machine in the previous process.

[0004] In order to meet various needs, the model size of the aluminum profile, especially the lower profile, is very diverse. Generally speaking, the height between the vertical head and the lower side of the lower profile of different model sizes is different as the vertical head height. Therefore, when the model size of the lower profile changes, the lower rolling wheel and the lower supporting roller need to be adjusted to move in the far and near directions so that the distance between them is adapted to the vertical head height of the lower profile after the model size changes.

[0005] However, since the rolling device in the existing rolling machine is usually fixedly arranged on the rack, the lower rolling wheel and the rack are synchronously raised or lowered. Therefore, in the prior art, in order to ensure that the height of the machine table of the rolling machine is consistent with the height of the machine table of the threading machine, a two-step adjustment method is usually adopted to adjust the distance between the lower rolling wheel and the lower supporting roller, that is, the height of the lower supporting roller is first adjusted to make the distance between the lower rolling wheel and the lower supporting roller adapt to the vertical head height of the lower profile after the model size changes, and then the height of the rack is adjusted to make the lower supporting roller return to the initial height. For example, for the larger size of the lower profile, the lower supporting roller is first lowered by a preset height relative to the lower rolling wheel, and then the machine table and the lower rolling roller are integrally raised by a preset height relative to the ground level; conversely, the same is true. However, this two-step adjustment method is not only inconvenient to operate, poor in precision, but also low in efficiency. SUMMARY

[0028] [EMBODIMENT]

[0029] Figure 1 is a structural schematic diagram of the break bridge heat insulation aluminum profile in the embodiment of the present application.

[0030] As shown in Figure 1 , the aluminum profile 500 after threading includes a lower profile 510, an upper profile 520 and two heat insulation bars 530.

[0032] After the heat insulation bars 530 are threaded into the corresponding upper notches 511 and lower notches 521, the outer side of the upper notches 511 as a vertical head 512 and the outer side of the lower notches 521 as a vertical head 522 need to be rolled to the inner side of the aluminum profile 500 respectively, so as to compress the heat insulation bars 530.

[0033] The size of the aluminum profile 500, especially the height of the lower profile 510, is usually different for different models.

[0034] Figure 2 is a perspective view of a broken bridge thermal insulation aluminum profile rolling machine in an embodiment of the present application; Figure 3 is a front view of a broken bridge thermal insulation aluminum profile rolling machine in an embodiment of the present application; Figure 4 is a cross-sectional view along A-A in Figure 3 .

[0035] As shown in Figure 2 to Figure 4 , in the present embodiment, the broken bridge thermal insulation aluminum profile rolling machine 100 is modified on the basis of an existing broken bridge thermal insulation aluminum profile rolling machine and is used to be placed on the ground plane 300 to perform rolling treatment on the profiled aluminum material 500 conveyed by the threading machine in the previous process, thereby obtaining the finished aluminum profile. The broken bridge thermal insulation aluminum profile rolling machine 100 comprises a rack 10, a rolling device 20, a profile conveying device 30, and a height adjusting device 40.

[0036] As shown in Figure 2 to Figure 4 , the rack 10 is a cuboid frame used to mount the rolling device 20, the profile conveying device 30, and the height adjusting device 40.

[0037] As shown in Figure 2 to Figure 4 , the rolling device 20 is fixedly arranged on the rack 10 and is used to perform rolling treatment on the vertical head 512 in the lower profile 510 and the vertical head 522 in the upper profile 520, respectively. The rolling device 20 comprises three rolling units 21 and a rolling wheel rotation driving unit 22.

[0038] The three rolling units 21 are sequentially and spacedly arranged on the rack 10 in the front-to-back direction, and each rolling unit 21 comprises a pair of rolling wheel assemblies 211 arranged in left and right opposition. Each rolling wheel assembly 211 has a lower rolling wheel 211a and an upper rolling wheel 211b for rolling the vertical head 512 in the lower profile 510 and the vertical head 522 in the upper profile 520, respectively.

[0039] The rolling wheel rotation driving unit 22 is arranged in the rack 10 and is connected with each rolling unit 21, and is used to simultaneously drive the lower rolling wheel 211a and the upper rolling wheel 211b in each rolling unit 21 to rotate.

[0040] As shown in Figure 2 to Figure 4 , the profile conveying device 30 is arranged on the rack 10 and is used to convey the profiled aluminum material 500 conveyed by the threading machine to the rolling device 20. The profile conveying device 30 comprises three profile conveying units 31 corresponding to the three rolling units 21, respectively.

[0041] Each profile conveying unit 31 is installed in front of the corresponding rolling unit 21 and includes a lower support roller assembly 311 for supporting and conveying the lower side of the aluminum profile 500 after strip insertion and an upper pressure roller assembly 312 for pressing and conveying the upper side of the aluminum profile 500 after strip insertion. The lower support roller assembly 311 and the upper pressure roller assembly 312 are respectively mounted on the frame 10 via a guide rail slider structure, thereby enabling them to rise or fall relative to the frame 10.

[0042] The lower support roller assembly 311 has a lower support roller 311a for supporting the lower side of the aluminum profile.

[0043] The upper pressure roller assembly 312 has an upper pressure roller 312a for pressing down on the upper side of the aluminum profile.

[0045] like Figure 2 to Figure 5 As shown, the height adjustment device 40 is installed inside the frame 10 and is connected to the rolling device 20 and the profile conveying device 30 respectively. It is used to adjust the movement of the lower rolling roller 211a and the lower support roller 311a in opposite directions, so that the distance between them is adapted to the height of the lower profile 510's vertical head 512 from its lower side, and to ensure that the height H of the lower support roller 311a relative to the ground plane 600 remains constant. The height adjustment device 40 includes four relatively independent lifting units 41, a lifting drive unit 42, and a support frame 43.

[0046] Figure 6 This is a three-dimensional structural diagram of the lifting unit in an embodiment of the present invention; Figure 7 This is a schematic diagram showing the disassembled installation of the lifting unit in an embodiment of the present invention.

[0047] like Figure 2 to Figure 7 As shown, four lifting units 41 are arranged at intervals along the circumference of the frame 10. In this embodiment, the four lifting units 41 are respectively located at the four corners of the frame 10. Since the four lifting units 41 have the same structure, the following description will take one lifting unit 41 as an example.

[0048] Each lifting unit 41 includes a support sleeve 411, a lifting screw 412, a bearing connection structure 413, a guide sleeve 414, and a supporting nut 415.

[0049] The support sleeve 411 is used to place on the ground plane 600. In this embodiment, the bottom of the support sleeve 411 is provided with a support 411a. The support sleeve 411 is a threaded sleeve, and its inner wall is provided with internal threads (not shown in the figure). In this embodiment, internal threads are only provided on the upper part of the inner wall of the support sleeve 411, reducing the difficulty and cost of processing. Of course, depending on actual needs, the entire inner wall of the support sleeve 411 can also be provided with internal threads.

[0050] The lifting screw 412 is vertically arranged and has an external thread that matches the internal thread of the support sleeve 411. The lower end of the lifting screw 412 is installed inside the support sleeve 411, and the upper end is mounted on the frame 10 in an axially fixed but circumferentially rotatable manner.

[0051] The bearing connection structure 413 is used to mount the lifting screw 412 on the frame 10 in an axially fixed but circumferentially rotatable manner. It includes a self-aligning bearing 413a, a thrust bearing 413b, and a fixing flange 413c. The self-aligning bearing 413a and the thrust bearing 413b are arranged sequentially from bottom to top at the upper end of the lifting screw 412. The fixing flange 413c is installed on the outside of the self-aligning bearing 413a and the thrust bearing 413b and is fixedly connected to the top of the frame 10.

[0052] The guide sleeve 414 is used to guide the rising or falling of the frame 10. It is movably sleeved on the outside of the corresponding support sleeve 411 and fixedly connected to the bottom of the frame 10. In this embodiment, the inner wall of the guide sleeve 411 has a limiting plane 414a, and the outer surface of the support sleeve 411 has a limiting plane 411a that matches the limiting plane 414a.

[0053] The support nut 415 is used to mount the support bracket 43 and drive the support bracket 43 to rise or fall relative to the frame 10. It is installed in the middle of the lifting screw 412 and fixedly connected to the corner of the corresponding support bracket 43. In this embodiment, the support nut 415 is a flanged round nut with an internal thread that has the same structure as the internal thread of the support sleeve 411 and matches the external thread of the lifting screw 412.

[0054] like Figure 2 , Figure 3 and Figure 5 As shown, the lifting drive unit 42 is used to simultaneously drive four lifting screws 142 to rotate, and includes a lifting drive component 421 and a transmission component 422.

[0055] The lifting drive component 421 is a servo motor, which is fixedly mounted on the frame 10.

[0056] The transmission component 422 has a driving sprocket 422a, four driven sprockets 422b, two tensioning sprockets 422c of the transmission chain, and a transmission chain 422d.

[0057] The drive sprocket 422a is mounted on the shaft of the lifting drive component 421.

[0058] Four driven sprockets 422b are respectively mounted on four lifting screws 412 and are located between the corresponding supporting nut 415 and the bearing connection structure 413.

[0059] Two tension sprockets 422c are mounted at the front and rear positions on the top of the frame 10 to adjust the tension of the drive chain, thereby ensuring that the drive chain 422d is in the proper tension state.

[0060] The drive chain 422d is mounted on the drive sprocket 422a, four driven sprockets 422b and two tension sprockets 422c, thereby transmitting the torque of the lifting drive component 421 to the lifting screw 412 of each lifting unit 41.

[0061] like Figure 2 and Figure 5 As shown, the support frame 43 is used to support all the lower support roller assemblies 311 in the profile conveying device 30 and drive the lower support roller assemblies 311 to rise or fall. It is a rectangular frame that matches the frame 10, and its four corners are respectively fixedly connected to the corresponding support nut 415.

[0062] The support frame 43 is provided with a number of support rod assemblies 431, each corresponding to one of the three lower support roller assemblies 311. Each support rod assembly has two support rods 431a, the lower end of which is fixedly connected to the support frame 43, and the upper end extends upward out of the frame 10 and is connected to the corresponding lower support roller assembly 311.

[0063] The role and effect of the embodiments

[0064] The thermally broken aluminum profile rolling machine described in this embodiment has a height adjustment device connected to both the rolling device and the profile conveying device. This device allows the lower support roller to rise or fall relative to the ground while simultaneously lowering or rising relative to the lower rolling roller, thus keeping the height of the lower support roller relative to the ground constant. Therefore, this embodiment can quickly and accurately adjust the distance between the lower rolling roller and the lower support roller while ensuring that the height of the lower support roller relative to the ground remains constant.

[0065] Furthermore, because the height adjustment device includes multiple lifting units, a lifting drive unit, and a support frame, and the lifting unit contains a support sleeve, a lifting screw, and a support nut, the support sleeve can be placed on the ground. The lifting screw is vertically arranged, with its lower end installed inside the support sleeve and its upper end connected to the lower rolling roller in an axially fixed but circumferentially rotatable manner. The support nut is installed in the middle of the lifting screw. Both the support nut and the support sleeve have internal threads that match the external threads of the lifting screw. The lifting drive unit is connected to multiple lifting screws respectively to drive multiple lifting screws to rotate simultaneously. The support frame is fixedly connected to multiple support nuts respectively to support the lower support roller. This makes the height adjustment device simple in structure, easy to manufacture and disassemble, and convenient to operate.

[0066] In addition, because the height adjustment device also includes multiple guide sleeves, which are movably fitted outside the corresponding support sleeves, it can play a good guiding role and further improve stability.

[0067] In addition, because the axially fixed and circumferentially rotatable structure is achieved through the bearing connection structure, which includes self-aligning bearings, thrust bearings, and fixed flanges, the structure is simple, the components are easy to purchase from the market, the cost is low, and it is easy to install and disassemble.

[0068] Furthermore, because the lifting drive unit includes a lifting drive component and a transmission component, the transmission component has a driving sprocket, multiple driven sprockets, and a transmission chain. The driving sprocket is mounted on the rotating shaft of the lifting drive component, the multiple driven sprockets are respectively mounted on multiple lifting screws, and the transmission chain is mounted on the driving sprocket and multiple driven sprockets, thus forming a chain drive mechanism with accurate transmission ratio, reliable operation, and high efficiency.

[0069] In addition, because the support frame is provided with a plurality of support rod assemblies corresponding to a plurality of lower support roller assemblies, each support rod assembly has two support rods, the lower end of the support rod is fixedly connected to the support frame, and the upper end is connected to the corresponding lower support roller assembly, the structure is simple, easy to process, and easy to disassemble and assemble.

[0070] The above embodiments are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.

[0071] For example, in the above embodiments, the lifting unit uses a double-nut screw linkage structure comprising a lifting screw, a support sleeve, and a supporting nut to link the lower rolling roller and the lower support roller. However, in this invention, the lifting unit can also use a double-rack gear linkage structure comprising one gear and two racks to link the lower rolling roller and the lower support roller. The gear is mounted on the frame and connected to the lower rolling roller, and the two racks are located on the same side of the gear and mesh with the gear respectively. One rack serves as a support rack for placement on the ground, and the other rack is fixedly connected to the support frame and thus connected to the lower support roller.
