Description

Technical Field

[0001] This application relates to the field of roll forming, and in particular to a roll forming apparatus for stable forming of strong steel. Background Technology

[0002] Currently, roll forming (also known as roll forming) is a plastic forming process that involves bending metal sheets laterally through multiple passes. Its basic principle is to feed the metal strip into a roll forming mill containing multiple pairs of rollers, with each pair of rollers gradually bending the sheet into the desired final shape.

[0003] In the prior art, a roller pressing device includes a base, a lower flat roller shaft rotatably connected to the base, and two symmetrically arranged lifting seats vertically connected to the base. An upper flat roller shaft is rotatably connected to the lifting seats. An upper roller and a lower roller are respectively arranged on the upper roller shaft and the lower flat roller shaft. The side walls of the upper roller and the lower roller that are close to each other are formed with a shaping cavity. The shaping cavity is used to process profiles and press the profiles into various shapes.

[0004] Regarding the aforementioned patents, during the process of use, the upper and lower rollers are prefabricated according to the shape of the profile to be pressed as required by the customer, and are made into various shapes to meet the processing needs of the profile. When making different profiles, the upper and lower rollers need to be prefabricated. When the product needs to be adjusted, the adjustment range of the existing technology is limited, and it can only be adjusted in one direction. Usually, the upper and lower rollers need to be remade, which urgently needs to be improved. Summary of the Invention

[0005] In order to improve the limit of the adjustment range of the forming cavity and improve the versatility of the roll-formed profile, this application provides a strong steel roll forming device with stable forming.

[0006] The present application provides a high-strength steel roll forming device with stable forming capabilities, which adopts the following technical solution: The device includes a base with multiple spaced-apart roller pressing seats. Each roller pressing seat includes a support seat fixed to the base, a rotating bottom shaft rotatably connected to the bottom of the support seat, and a lower flat roller detachably connected to the rotating bottom shaft. A rotating top shaft is vertically connected to the support seat, and an upper flat roller is detachably connected to the rotating top shaft. The support seat has a first adjustment device for adjusting the height of the rotating top shaft. The upper flat roller and the lower flat roller are positioned opposite each other for pressing profiles vertically. Auxiliary seats are adjustablely connected to both sides of the lower flat roller, and side flat rollers are rotatably connected to the auxiliary seats. The side flat rollers are detachably connected to the auxiliary seats. The support seat has a second adjustment device for adjusting the distance between the auxiliary seats and the lower flat rollers. Limiting annular grooves are formed on both the upper and lower sides of the side flat rollers, and the limiting annular grooves are respectively inserted into the upper and lower flat rollers. The two side flat rollers, the upper flat roller, and the lower flat roller form a molding cavity for pressing the profile groove.

[0007] By adopting the above technical solution, during use, once the profile size is determined, the positions of the first and second adjustment devices on each roller press seat are adjusted according to the required pressed shape. This allows for adjustment of the distance between the upper and lower flat rollers, as well as the distance between the two side flat rollers, thereby controlling the dimensions of the molding cavity in four directions. Furthermore, during use, reducing the distance between the side flat rollers, upper flat roller, and lower flat roller can reduce the occurrence of undercuts, ensuring the pressing effect of the product. When fine-tuning is required, the positions of the side flat rollers, upper flat roller, and lower flat roller can be adjusted to allow for minor adjustments, better adapting to engineering needs. When changing the pressing size, the side flat rollers, upper flat roller, and lower flat roller can be replaced, adapting to various profile sizes. Furthermore, by using different sized parts, the prefabrication quantity of the side flat rollers, upper flat roller, and lower flat roller can be reduced, lowering the cost of pressing different sized profiles each time, increasing the adjustment limit of the molding cavity range, and improving the versatility of the rolled profiles.

[0008] Preferably, the upper flat roller and the lower flat roller are respectively provided with upper insertion holes and lower insertion holes for insertion into the rotating top shaft and rotating bottom shaft, respectively. The inner walls of the upper insertion hole and the lower insertion hole are each provided with a first insertion hole, and the outer walls of the upper flat roller and the lower flat roller are provided with a second insertion hole. The first insertion hole and the second insertion hole form a positioning hole, and a positioning pin is inserted into the positioning hole. A positioning shaft is inserted into the auxiliary seat, and the side flat roller is provided with a positioning insertion hole for insertion into the positioning shaft.

[0009] By adopting the above technical solution, the upper and lower flat rollers can be detachably fixed by using positioning pins and positioning holes, making them easier to replace and improving the convenience of using the upper and lower flat rollers. Furthermore, the use of positioning pins makes it easier to install the side flat rollers, further improving their convenience.

[0010] Preferably, a plurality of synchronous plugs are installed in a circumferential array at the corner of the limiting ring groove, and the upper flat roller and the lower flat roller are provided with synchronous slots on both sides of the circumferential array to engage with the synchronous plugs.

[0011] By adopting the above technical solution, the synchronous insert and the synchronous slot cooperate to enable the side flat roller, the upper flat roller and the lower flat roller to rotate synchronously, thereby better pressing the profile and improving the profile processing effect.

[0012] Preferably, both the upper flat roller and the lower flat roller are provided with positioning blocks on their sidewalls, and both the upper flat roller and the lower flat roller are provided with positioning slots that engage with the positioning blocks on their inner walls. Both the upper flat roller and the lower flat roller are provided with positioning holes that communicate with the positioning slots on their sidewalls, and locking bolts are inserted into the positioning holes. The locking bolts are threadedly connected to the positioning blocks.

[0013] By adopting the above technical solution, when in use, the upper flat roller and the lower flat roller are respectively inserted into the rotating top shaft and the rotating bottom shaft, so that the positioning block is inserted into the positioning slot, and then locked with the locking bolt, thereby realizing the locking of the upper flat roller and the lower flat roller, improving the convenience of installing and disassembling the upper flat roller and the lower flat roller.

[0014] Preferably, the positioning block has a threaded adjustment hole, which is coaxial with the positioning hole. An adjustment stud is threadedly connected to the threaded adjustment hole, and a connecting screw hole is provided on the side of the adjustment stud near the locking bolt, which is threadedly connected to the locking bolt.

[0015] By adopting the above technical solution, during use, the position of the adjusting stud is moved so that it abuts against the bottom of the positioning slot, and then fixed with the locking bolt. This allows the position of the upper or lower flat roller to be adjusted, thus making the upper and lower flat rollers misaligned, thereby adapting to the pressing of various profiles.

[0016] Preferably, the adjusting stud is provided with an abutment piece at one end near the locking bolt, and a buffer pad is provided on the side of the abutment piece away from the positioning block.

[0017] By adopting the above technical solution, the upper or lower flat roller can be better supported by the abutment piece and the buffer pad, thereby improving the firmness of the upper or lower flat roller.

[0018] Preferably, the upper flat roller is composed of two arc-shaped connecting pieces. One arc-shaped connecting piece has insertion blocks at both ends, and the other arc-shaped connecting piece has insertion holes at both ends that engage with the insertion blocks. A sliding cavity is formed through the side wall of the insertion block, and a sliding guide block is slidably connected in the sliding cavity. The thickness of the sliding guide block gradually decreases in the direction away from the insertion block. A guide groove is formed on the side wall of the insertion block that engages with the sliding guide block. A tightening bolt is threadedly connected to the side wall of the arc-shaped connecting piece. The tightening bolt is used to push the sliding guide block into the guide groove.

[0019] By adopting the above technical solution, during use, the two arc-shaped connecting pieces are tightly clamped together with the rotating top shaft, the plug block is inserted into the plug hole, and the tightening bolt pushes the sliding guide block into the guide pressure groove, thereby connecting the two arc-shaped connecting pieces together more firmly and improving the convenience of replacing and using the upper flat roller.

[0021] By adopting the above technical solution, during use, the two arc-shaped connecting pieces are inserted together, and the limiting strip cooperates with the limiting groove, so that the limiting strip can be squeezed into the limiting groove. The use of arc-shaped connecting pieces can fix it more firmly.

[0022] Preferably, one of the arc-shaped connecting pieces is provided with connecting cards at both ends, and the other arc-shaped connecting piece is provided with connecting slots at both ends. The outer wall of the connecting card is provided with friction protrusions, and the side wall of the connecting slot is provided with friction grooves that engage with the friction protrusions.

[0023] By adopting the above technical solution, during use, the friction convex strip can make the two arc-shaped connecting pieces more firmly connected together, thereby improving the firmness of the arc-shaped connecting pieces.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. During use, once the profile dimensions are determined, adjust the positions of the first and second adjustment devices on each roller press seat according to the required pressed shape. This allows adjustment of the distance between the upper and lower flat rollers, and the distance between the two side flat rollers, thus controlling the dimensions of the molding cavity in four directions. Furthermore, by reducing the distance between the side flat rollers, upper flat roller, and lower flat roller, the occurrence of stubble can be reduced, ensuring the pressing effect of the product. When fine-tuning is required, the positions of the side flat rollers, upper flat roller, and lower flat roller can be adjusted to make minor adjustments, better adapting to engineering needs. When changing the pressing size, the side flat rollers, upper flat roller, and lower flat roller can be replaced to accommodate various profile sizes. By using different sized parts, the pre-fabrication quantity of the side flat rollers, upper flat roller, and lower flat roller can be reduced, lowering the cost of pressing different sized profiles each time, increasing the adjustment limit of the molding cavity range, and improving the versatility of the rolled profiles. 2. During use, the two arc-shaped connecting pieces are engaged with the rotating top shaft to clamp together. The plug block is inserted into the plug hole, and the bolt is tightened to push the sliding guide block into the guide groove. This allows the two arc-shaped connecting pieces to be connected more firmly, improving the convenience of replacing and using the flat roller. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1 - Figure 8 This application will be described in further detail.

[0027] This application discloses a strong steel roll forming apparatus that provides stable forming.

[0028] Example 1 Reference Figure 1 A stable high-strength steel roll forming device includes a base 1, which is a rectangular plate. Multiple spaced roll forming seats are mounted on the base 1. Each roll forming seat includes a support seat 5 fixed to the base 1. The support seat 5 is H-shaped, and a rotating bottom shaft 2 is rotatably connected to the bottom of the support seat 5. A lower flat roller 8 is detachably connected to the rotating bottom shaft 2. A rotating top shaft 3 is vertically connected to the support seat 5, and an upper flat roller 6 is detachably connected to the rotating top shaft 3. A first adjustment device for adjusting the height of the rotating top shaft 3 is installed on the support seat 5. The upper flat roller 6 and the lower flat roller 8 are arranged opposite each other for pressing grooves. Auxiliary seats 13 are adjustablely connected to both sides of the lower flat roller 8. Side flat rollers 12 are rotatably connected to the auxiliary seats 13 and detachably connected to the auxiliary seats 13. A second adjustment device for adjusting the distance between the auxiliary seats 13 and the lower flat roller 8 is installed on the support seat 5. Limiting annular grooves 44 are formed on both the upper and lower sides of the side flat roller 12, and the limiting annular grooves 44 are respectively inserted into and engaged with the upper flat roller 6 and the lower flat roller 8. The two side flat rollers 12, the upper flat roller 6, and the lower flat roller 8 form a shaping cavity 7 for pressing the molding groove. The shaping cavities 7 on the multiple roller presses are arranged opposite each other, which makes it easier to process the profile 4.

[0029] The upper flat roller 6 and the lower flat roller 8 are respectively provided with upper insertion holes and lower insertion holes that are inserted and cooperate with the rotating top shaft 3 and the rotating bottom shaft 2. The inner walls of the upper insertion holes and the lower insertion holes are provided with first insertion holes 21, and the outer walls of the upper flat roller 6 and the lower flat roller 8 are provided with second insertion holes 22. The first insertion holes 21 and the second insertion holes 22 are both rectangular holes and are arranged opposite to each other. The first insertion holes 21 and the second insertion holes 22 form a positioning hole, and a positioning pin 20 is inserted into the positioning hole. A positioning shaft 19 is inserted into the auxiliary seat 13, and a positioning insertion hole is provided on the side flat roller 12 that is inserted and cooperates with the positioning shaft 19.

[0030] The support base 5 consists of two support columns 51 fixed to the base 1. The first adjustment device includes a lifting slider 18 slidably connected to the support column 51, a rotating base shaft 2 rotatably connected to the lifting slider 18, and a first adjusting stud 17 threadedly connected to the support column 51. The bottom of the first adjusting stud 17 is rotatably connected to the lifting slider 18. The second adjustment device includes multiple second adjusting studs 11 threadedly connected to the auxiliary base 13. The side of the second adjusting stud 11 away from the auxiliary base 13 abuts against the support column 51, improving the convenience of pressing the profile 4. During use, once the profile 4 is sized, the positions of the first and second adjustment devices on each roller press are adjusted according to the desired pressed shape. This allows adjustment of the distance between the upper flat roller 6 and the lower flat roller 8, as well as the distance between the two side flat rollers 12, thereby controlling the dimensions of the molding cavity 7 in four directions. Furthermore, by reducing the distance between the side flat rollers 12, the upper flat roller 6, and the lower flat roller 8, the occurrence of drooping ends is reduced, ensuring the pressing effect of the product. When fine-tuning is required, the positions of the side flat rollers 12, the upper flat roller 6, and the lower flat roller 8 are adjusted to make minor adjustments, better adapting to engineering needs. When changing the pressing size, the side flat rollers 12, the upper flat roller 6, and the lower flat roller 8 are replaced, allowing for the adaptation to various profile 4 sizes. Furthermore, by using different sized parts, the pre-fabrication quantity of the side flat rollers 12, the upper flat roller 6, and the lower flat roller 8 can be reduced, lowering the cost of pressing different sized profiles 4 each time, increasing the adjustment limit of the molding cavity 7, and improving the versatility of the roller-pressed profile 4.

[0031] A rectangular plate 9 is installed on both sides of the support column 51. Multiple positioning holes are provided on the side wall of the support column 51. Adjustment holes 14 are provided near the sides of the horizontal plate 9, and positioning bolts 15 are inserted into the adjustment holes 14. The positioning bolts 15 are threadedly connected to the positioning holes. Locking holes 26 are provided on both sides of the auxiliary seat 13, and locking bolts 10 are threadedly connected to the horizontal plate 9 in the locking holes 26, thereby more stably fixing the auxiliary seat 13. A support screw 16 is threadedly connected to the bottom of the horizontal plate 9, and the bottom of the support screw 16 abuts against the base 1.

[0032] The implementation principle of the high-strength steel roll forming device with stable forming in this application embodiment is as follows: During use, after the size of the profile 4 is determined, the position of the first adjustment device and the second adjustment device on each roll forming seat is adjusted according to the shape to be pressed. This allows adjustment of the distance between the upper flat roller 6 and the lower flat roller 8, and the distance between the two side flat rollers 12. This enables control of the dimensions of the forming cavity 7 in four directions. Furthermore, during use, by reducing the distance between the side flat rollers 12, the upper flat roller 6, and the lower flat roller 8, the occurrence of undercut can be reduced, ensuring the product pressing is stable. The effect is that when fine-tuning is required, the positions of the side flat roller 12, the upper flat roller 6, and the lower flat roller 8 can be adjusted to make minor adjustments, thereby better adapting to engineering needs. When changing the pressing size, the side flat roller 12, the upper flat roller 6, and the lower flat roller 8 can be replaced to adapt to various different sizes of profiles 4. Furthermore, by matching different sized parts, the prefabrication amount of the side flat roller 12, the upper flat roller 6, and the lower flat roller 8 can be reduced, thereby reducing the cost of pressing different sizes of profiles 4 each time, increasing the adjustment limit of the molding cavity 7, and improving the versatility of the roll-pressed profiles 4.

[0033] Example 2 Reference Figure 5 The difference between this embodiment and Embodiment 1 is that multiple synchronous plugs 30 are installed in a circumferential array at the corner of the limiting ring groove 44, and synchronous slots 33 are opened on both sides of the upper flat roller 6 and the lower flat roller 8 to engage with the synchronous plugs 30. Multiple telescopic grooves 32 are opened in the circumferential array at the corner of the limiting ring groove 44, and the synchronous plugs 30 engage with the telescopic grooves 32. A telescopic compression spring 31 for driving the synchronous plugs 30 to extend is installed in the telescopic groove 32. The telescopic synchronous plugs 30 can stably limit the fine-tuning of the upper and lower flat rollers 8, so that the upper and lower flat rollers 8 can move more conveniently.

[0034] Both the upper flat roller 6 and the lower flat roller 8 have positioning blocks 23 installed on their side walls. Each side wall of the upper flat roller 6 and the lower flat roller 8 has a positioning slot that engages with the positioning block 23. Each side wall of the upper flat roller 6 and the lower flat roller 8 also has a positioning hole that communicates with the positioning slot. A locking bolt 24 is inserted into the positioning hole, and the locking bolt 24 is threaded onto the positioning block 23. The upper flat roller 6 and the lower flat roller 8 are then inserted into the rotating top shaft 3 and the rotating bottom shaft 2, respectively, so that the positioning block 23 is inserted into the positioning slot. The locking bolt 24 is then used to lock the upper flat roller 6 and the lower flat roller 8.

[0035] The positioning block 23 has a threaded adjustment hole, which is coaxial with the positioning hole. An adjusting stud 25 is threadedly connected to the adjusting hole. The adjusting stud 25 has a connecting screw hole 27 on the side near the locking bolt 24, which is threadedly connected to the locking bolt 24. An abutment piece 28 is fixed to the end of the adjusting stud 25 near the locking bolt 24, and a buffer pad 29 is fixed to the side of the abutment piece 28 away from the positioning block 23. By moving the position of the adjusting stud 25, it abuts against the bottom of the positioning slot and is then fixed with the locking bolt 24. This allows the position of the upper flat roller 6 or the lower flat roller 8 to be adjusted, thus allowing the upper flat roller 6 and the lower flat roller 8 to be misaligned, thereby adapting to the pressing of various profiles 4.

[0036] The implementation principle of Example 2 is as follows: by moving the position of the adjusting stud 25, the adjusting stud 25 is made to abut against the bottom of the positioning slot, and then fixed with the locking bolt 24, so that the position of the upper flat roller 6 or the lower flat roller 8 can be adjusted, so that the upper flat roller 6 and the lower flat roller 8 can be misaligned, thereby achieving the ability to adapt to the pressing of various different profiles 4.

[0037] Example 3 Reference Figure 7 Both the upper flat roller 6 and the lower flat roller 8 are composed of two arc-shaped connecting pieces 61. One arc-shaped connecting piece 61 has two ends fixed with insertion blocks 40, and the other arc-shaped connecting piece 61 has insertion holes at both ends that are engaged with the insertion blocks 40. The side wall of the insertion block 40 has a sliding cavity 43 through which a sliding guide block 41 is slidably connected. The thickness of the sliding guide block 41 gradually decreases in the direction away from the insertion block 40. The side wall of the insertion block 40 has a guide groove 42 that is engaged with the sliding guide block 41. The side wall of the arc-shaped connecting piece 61 is threaded with a tightening bolt 35, which is used to push the sliding guide block 41 into the guide groove 42.

[0038] A limiting groove 37 is provided on the side wall of the rotating top shaft 3. One of the arc-shaped connecting pieces 61 has a limiting strip 34 integrally formed at both ends, and the end of the limiting strip 34 abuts against the limiting groove 37. The other arc-shaped connecting piece 61 has a limiting groove 36 on its inner side that engages with the limiting strip 34. The thickness of the limiting groove 36 gradually increases along the direction close to the limiting strip 34. One of the arc-shaped connecting pieces 61 has connecting cards 38 fixed at both ends, and the other arc-shaped connecting piece 61 has connecting grooves 39 at both ends. The outer wall of the connecting card 38 has a friction protrusion integrally formed, and the side wall of the connecting groove 39 has a friction groove that engages with the friction protrusion.

[0039] The implementation principle of Example 3 is as follows: During use, the two arc-shaped connecting pieces 61 are engaged with the rotating top shaft 3 to clamp together, the plug block 40 is inserted into the plug hole, and the tightening bolt 35 pushes the sliding guide block 41 into the guide pressure groove 42, so that the two arc-shaped connecting pieces 61 can be more firmly connected together, improving the convenience of replacing and using the flat roller 6.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
