Description

[0001] This application belongs to the technical field of steel strip flattening, and more specifically, relates to a steel strip flattening device for manufacturing automotive sealing strip skeletons. Background Technology

[0002] The automotive sealing strip skeleton is the core supporting component of the automotive sealing strip, and the precision flattening of the steel strip is a key preliminary process before roll forming. The adjustment accuracy of the gap between the upper and lower pressure rollers in the flattening device directly determines the flatness and overall thickness consistency of the flattened steel strip, ultimately affecting the forming dimensional accuracy and assembly sealing performance of the sealing strip skeleton.

[0003] The existing steel strip flattening device generally adopts a vertical straight adjustment structure with a screw. The specific structure is as follows: the two ends of the upper pressure roller are respectively installed in the bearing seat, and the two bearing seat are correspondingly slidably assembled in the vertical guide grooves on both sides of the frame, which can only slide in the vertical direction; the adjusting screw is vertically inserted through the top plate of the frame, the bottom end of the screw is rotatably connected to the top surface of the bearing seat, and the top end of the screw extends out of the top plate of the frame and is connected to the handwheel.

[0004] Due to the inherent limitations of thread machining accuracy and thread clearance, the adjustment resolution of this type of structure is usually only 0.05 to 0.1 mm, which cannot meet the requirements of micron-level precision adjustment.

[0027] The steel strip flattening device for manufacturing automotive sealing strip skeletons provided in this application will now be described.

[0028] like Figure 1 and Figure 2 As shown, one embodiment of this application provides a steel strip flattening device for manufacturing automotive sealing strip skeletons, including a frame 1 and an upper pressure roller and a lower pressure roller disposed on the frame 1. The steel strip flattening device for manufacturing automotive sealing strip skeletons also includes two sets of adjustment mechanisms, which are respectively disposed at both ends of the upper pressure roller.

[0029] The adjustment mechanism includes an adjustment frame 2, a lower pressure block 3, a moving component 4, and an elastic support component 5. The adjustment frame 2 is vertically slidably mounted on the frame 1 and rotatably connected to the corresponding end of the upper pressure roller. The lower pressure block 3 is horizontally slidably mounted on the frame 1 and located above the corresponding adjustment frame 2. The bottom surface of the lower pressure block 3 is inclined along its own sliding direction, and the inclined surface of the lower pressure block 3 is used to press the adjustment frame 2 downward.

[0030] The movable component 4 is mounted on the frame 1 and connected to the lower pressure block 3. The movable component 4 is used to move the lower pressure block 3. The elastic support component 5 is mounted at the bottom of the frame 1 and located below the adjustment frame 2. The elastic support component 5 is always in a compressed state and is used to push the adjustment frame 2 upward.

[0031] The steel strip flattening device for manufacturing automotive sealing strip skeleton provided in this embodiment, compared with the prior art, adopts a gap adjustment method in which the lower pressure block 3 moves laterally and the inclined surface drives the vertical movement of the adjustment frame 2. The lateral displacement of the moving component 4 is converted into the vertical displacement of the adjustment frame 2. With the help of the deceleration and force amplification characteristics of the inclined surface, the resolution of the roller gap adjustment can be improved, which helps to achieve more precise gap adjustment.

[0032] Meanwhile, the elastic support component 5 is always in a compressed state and presses upward against the adjustment frame 2, which can keep the inclined surface of the adjustment frame 2 and the lower pressure block 3 in contact, offsetting the fit clearance of the threaded pair. Under the vibration condition of the equipment operation, it helps to maintain the stability of the roll gap, improve the flatness and full width thickness consistency of the flattened steel strip, and provide a stable foundation for the roll forming of the subsequent automotive sealing strip skeleton.

[0033] like Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The adjustment mechanism also includes a positioning component 6, which is connected between the frame 1 and the corresponding adjustment frame 2. The positioning component 6 is used to fix or release the adjustment frame 2 relative to the frame 1.

[0034] The steel strip flattening device for manufacturing automotive sealing strip skeletons also includes a power switching mechanism 7. The power switching mechanism 7 is mounted on the frame 1 and connected between the moving component 4 and the positioning component 6. The power switching mechanism 7 is used to provide power to the moving component 4 or the positioning component 6 individually, so as to move the lower pressing block 3 or fix or release the adjusting frame 2 relative to the frame 1.

[0035] After the roll gap adjustment is completed, the positioning component 6 can fix the adjusting frame 2 relative to the frame 1, sharing the vibration load on the adjusting frame 2 during operation, reducing the force fluctuation on the contact surface between the lower pressure block 3 and the adjusting frame 2, and further improving the long-term stability of the roll gap state. The power switching mechanism 7 can switch the power output between the moving component 4 and the positioning component 6, eliminating the need for two separate power sources, which helps to simplify the power layout of the device, reduce the number of power components, and optimize the overall spatial structure of the device.

[0036] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The moving component 4 includes a moving screw 41, a first power shaft 42, and a first bevel gear set 43; the moving screw 41 is laterally rotatably mounted on the frame 1 and threadedly connected to the corresponding lower pressure block 3; the first power shaft 42 is laterally rotatably mounted on the frame 1 and perpendicular to the moving screw 41; the first bevel gear set 43 is drively connected between the moving screw 41 and the first power shaft 42.

[0037] Among them, the two sets of moving components 4 share a first power shaft 42, and the power switching mechanism 7 is used to drive the first power shaft 42 to rotate.

[0038] The transmission structure, employing a movable screw 41 in conjunction with a first bevel gear set 43 and a first power shaft 42, can stably convert the rotation of the first power shaft 42 into the lateral translation of the lower pressure block 3. The transmission path is clear, and the motion transmission is smooth and reliable. The two sets of movable components 4 share a single first power shaft 42, ensuring the synchronous movement of the lower pressure blocks 3 at both ends. This helps maintain consistent vertical adjustment at both ends of the upper pressure roller, ensuring the parallelism between the upper and lower pressure roller axes and improving the uniformity of the flattened thickness across the entire width of the steel strip.

[0039] like Figure 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The elastic support assembly 5 includes a connecting frame 51, a telescopic column 52, and a support spring (not shown in the figure); the connecting frame 51 is fixed to one side of the adjusting frame 2; the telescopic column 52 is vertically connected between the bottom of the frame 1 and the bottom surface of the connecting frame 51; the support spring is set inside the telescopic column 52 and is always in a compressed state.

[0040] The structure employs a connecting frame 51 in conjunction with a telescopic column 52 and a support spring. The telescopic column 52 guides the deformation direction of the support spring, preventing radial deflection and ensuring stable vertical transmission of the support force. The support spring remains compressed, continuously providing an upward clamping force to the adjusting frame 2, ensuring reliable contact between the adjusting frame 2 and the inclined surface of the lower pressure block 3. This maintains the stability of the gap adjustment structure and mitigates the adverse effects of equipment vibration on the roll gap accuracy.

[0041] like Figure 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The positioning component 6 includes a translation frame 61 and a translation screw 62; the translation frame 61 is slidably mounted on the corresponding adjustment frame 2 along the axial direction of the upper pressure roller, and the end of the translation frame 61 facing the frame 1 is wedge-shaped, and the frame 1 is vertically provided with an extrusion groove for the end of the translation frame 61 to be inserted and extruded.

[0042] The translation screw 62 is rotatably mounted on the adjusting frame 2 along the axial direction of the upper pressure roller and is threadedly connected to the translation frame 61; the translation screw 62 is used to drive the power switching mechanism 7 to rotate.

[0043] The structure adopts a wedge-shaped translation frame 61 that cooperates with the extrusion groove on the frame 1. The translation frame 61 is driven to move axially along the upper pressure roller by the translation screw 62, so that the wedge-shaped end of the translation frame 61 is inserted into the extrusion groove and generates extrusion force. The relative fixation between the adjustment frame 2 and the frame 1 is achieved by the expansion and tightening effect of the wedge surface. The fixing method is reliable, and the degree of expansion and tightening can be adjusted by rotating the translation screw 62 to adapt to the fixing requirements under different working conditions.

[0044] like Figure 4 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The positioning assembly 6 also includes a drive shaft 63, a second bevel gear set 64, a second power shaft 65, and a third bevel gear set 66; the drive shaft 63 is rotatably mounted on the adjusting frame 2 along the moving screw 41; the second bevel gear set 64 is drively connected between the translation screw 62 and the drive shaft 63.

[0045] The second power shaft 65 is rotatably mounted on two adjusting frames 2 along the first power shaft 42. In this embodiment, the second power shaft 65 is specifically rotatably connected to two connecting frames 51; the third bevel gear set 66 is drive-connected between the transmission shaft 63 and the second power shaft 65.

[0046] Among them, the two sets of positioning components 6 share a second power shaft 65, which is located directly below the first power shaft 42. The power switching mechanism 7 is also used to drive the second power shaft 65 to rotate.

[0047] The transmission link formed by the second bevel gear set 64, the drive shaft 63, the third bevel gear set 66, and the second power shaft 65 can synchronously transmit the rotation of the second power shaft 65 to the translation screws 62 on both sides, realizing the synchronous action of the two sets of positioning components 6, ensuring that the fixing force of the adjusting brackets 2 at both ends is uniform and consistent, and avoiding the problem of uneven load caused by insufficient fixing on one side. The second power shaft 65 is located directly below the first power shaft 42, and the vertically arranged structure is compact, which helps to save the lateral installation space of the device and makes the overall transmission layout more regular.

[0048] like Figure 5 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The power switching mechanism 7 includes a first transmission gear 71, a second transmission gear 72, a power gear 73, a power motor 74, and a lifting assembly 75. The first transmission gear 71 is coaxially fixed on the first power shaft 42; the second transmission gear 72 is coaxially fixed on the second power shaft 65 and is located directly below the first transmission gear 71.

[0049] The power gear 73 is located between the first transmission gear 71 and the second transmission gear 72. The power gear 73 is used to mesh with either the first transmission gear 71 or the second transmission gear 72 independently. The output shaft of the power motor 74 is coaxially fixed with the power gear 73. The lifting assembly 75 is mounted on the frame 1 and connected to the power motor 74 body. The lifting assembly 75 is used to drive the power motor 74 to lift.

[0050] The power switching mechanism 7 employs a lifting power gear 73 that meshes with the first transmission gear 71 and the second transmission gear 72 respectively. The power output path is switched through the vertical movement of the power gear 73. The transmission ratio remains stable and the power transmission is reliable during the switching process. Only one power motor 74 is needed to drive the moving component 4 and the positioning component 6 respectively, which helps to reduce the number of power components and lower the manufacturing and daily maintenance costs of the device.

[0051] like Figure 5 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The lifting assembly 75 includes a lifting frame 751 and a drive cylinder 752; the lifting frame 751 is vertically slidably mounted on the frame 1 and is used to mount the power motor 74; the drive cylinder 752 is vertically mounted on the frame 1 and connected to the lifting frame 751, and the drive cylinder 752 is used to drive the lifting frame 751 to slide.

[0052] The drive cylinder 752 can drive the lifting frame 751 to slide smoothly vertically, thereby driving the power motor 74 and the power gear 73 to lift synchronously. The lifting action is responsive and the position control is accurate, which can ensure the meshing accuracy of the power gear 73 and the corresponding transmission gear, and ensure the smoothness of the power switching process and the transmission stability.

[0053] like Figures 4 to 5 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The frame 1 includes an upper frame 11 and a lower frame 12 that are detachably connected by multiple bolts. The moving assembly 4 and the lifting assembly 75 are both mounted on the upper frame 11.

[0054] The moving component 4 and the lifting component 75 are both integrated on the upper frame 11, which facilitates the assembly and disassembly of the upper adjustment mechanism as a whole, making it convenient for the production assembly, later maintenance and component replacement of the device. At the same time, the lower frame 12 of the corresponding size can be adapted to different pressure roller specifications, improving the adaptability of the device to different production needs.

[0055] like Figure 1 and Figure 6 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The steel strip flattening device for manufacturing automotive sealing strip skeletons also includes a drive assembly 8 for driving the upper pressure roller to rotate. The drive assembly 8 includes a follower frame 81, a first drive gear, a second drive gear, and a drive motor 82. The follower frame 81 is fixed above one of the adjusting frames 2, and the top of the follower frame 81 is slidably connected to the upper frame 11.

[0056] The first drive gear is coaxially fixed to the upper pressure roller; the second drive gear is rotatably mounted on the follower frame 81 and meshes with the first drive gear; the drive motor 82 is mounted on the follower frame 81 and is connected to the second drive gear for transmission.

[0057] The drive assembly 8 adopts a structure in which the follower frame 81 moves synchronously with the adjusting frame 2, ensuring that the second drive gear and the first drive gear are always engaged. After the upper pressure roller completes its vertical adjustment, there is no need to readjust the meshing position of the drive gears, thus continuously providing rotational power to the upper pressure roller and ensuring the continuity of the flattening operation. The top of the follower frame 81 is slidably connected to the upper frame 11, which provides guidance for the vertical movement of the follower frame 81 and improves the operational stability of the drive assembly 8 during the follow-up process.

[0058] In this embodiment, a protective cover can also be installed on the frame 1 to shield and protect each gear.
