Description

Technical Field

[0001] This invention relates to the field of steel plate forming technology, and more specifically, to a steel plate forming assembly and a production equipment having the forming assembly. Background Technology

[0002] Corrugated steel sheets are produced by processing flat steel sheets. By processing the surface of the steel sheet to form corrugated grooves, the overall strength of the corrugated steel sheet can be increased, especially the strength along the direction of the corrugated grooves. They are usually made of thin steel sheets, such as steel coils.

[0003] There are generally two methods for forming corrugated steel sheets. The first is roll forming, which uses a corrugated sheet roll forming mill. The steel coil is fed in along the conveyor direction and, under the action of the concave and convex structures on the pressure rollers, a corrugated structure is formed on the steel sheet. This processing method has a faster corrugated structure forming speed and higher production efficiency. However, in this type of processing, the corrugated grooves are distributed along the length of the steel coil, and the width of the corrugated steel sheet is the same as the width of the steel coil. Due to the size limitation of the steel coil, the number of corrugated grooves in this type of corrugated steel sheet is limited, thus restricting the width of the corrugated sheet.

[0004] The second method uses molding, such as Figure 1 As shown, the upper and lower dies cooperate with each other, and the steel coil is conveyed by a conveyor device and extruded between the upper and lower dies. Corrugated grooves are formed sequentially along the length of the steel plate, creating a corrugated structure through the continuous arrangement of these grooves. In this processing method, the corrugated plates have grooves oriented along the width of the steel coil, while the arrangement of each groove follows the length of the coil. Therefore, the number and dimensions of the grooves in a single corrugated steel plate can be adjusted, making it suitable for producing steel plates requiring continuous multi-corrugated structures on a single plate.

[0005] However, in the second processing method, because the steel plate is bent from a straight line under the pressure of the upper and lower dies, the length of the steel plate between the upper and lower dies will increase. Therefore, during the pressure forming process, the steel plates on both sides of the extrusion position need to move towards the middle. The direct change is that the steel plates on both sides need to move towards the extrusion part, i.e., the sides shrink towards the middle. Furthermore, it is difficult to control the amount of movement of the steel plates on both sides towards the forming position. This will result in the inaccurate control of the spacing between the two corrugated grooves on the corrugated steel plate, affecting the accuracy of this type of corrugated plate production.

[0006] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0007] The purpose of this invention is to solve the above-mentioned problems by providing a steel plate forming component that can more accurately control the spacing between corrugated grooves, improve the accuracy of corrugated steel plate extrusion forming, and is applicable to the production of steel plates with continuous multi-corrugated structures on a single plate.

[0010] The invention is further configured such that the upper mold has a vertically penetrating channel corresponding to the position of the corrugated boss, the width of the channel being the same as the width of the corrugated boss, and a guide sliding mechanism is provided in the channel, the guide sliding mechanism including a guide pulley; a hydraulic rod three is provided at the upper part of the guide sliding mechanism, and is driven to rise and fall by the hydraulic rod three, the guide pulley in the guide sliding mechanism can extend downward to the lower side of the corrugated boss, and is used for rolling and guiding the steel plate between the corrugated boss and the corrugated groove.

[0011] The present invention is further configured such that several groups of channels are evenly arranged in the width direction of the boss, and the guide sliding mechanism corresponds one-to-one with the channel.

[0012] The present invention is further configured such that the guide slide mechanism includes a guide slide frame, a rotating shaft, a connecting seat, a pressure block, and a bracket. The guide slide frame is fixedly connected to the lower part of the output end of the hydraulic rod three. The connecting seat is rotatably connected to the lower end of the guide slide frame through the rotating shaft. The bracket and the pressure block are fixedly connected to the outer periphery of the connecting seat. The bracket and the pressure block are located on both sides of the axis and are 180° apart. The guide pulley is rotatably connected to the bracket. The contour of the pressure block is adapted to the contour of the corrugated boss and is used to extrude the steel plate at the channel position.

[0013] The present invention is further configured such that the connecting seat is fixedly connected to the rotating shaft, and the guide pulley and the pressure block can be switched up and down by rotation; the channel is provided with a sliding groove on the two sides corresponding to the two ends of the rotating shaft, and a slider is fixedly connected to both ends of the rotating shaft. The two sliders are respectively embedded in the sliding groove and can be guided up and down.

[0014] The invention is further configured such that a switching mechanism is provided on the upper part of the upper mold, the switching mechanism having a rotatable linkage shaft, the linkage shaft corresponding to the upper outer side of the channel, the end of the linkage shaft being connected to a linkage seat, the linkage seat having a linkage groove on the side facing the channel, the linkage groove being adapted to the slider; after the guide mechanism is adjusted upward, the slider slides into the linkage groove, and the rotating shaft is coaxial with the linkage shaft; the rotation of the linkage shaft drives the rotating shaft to rotate, switching the guide pulley and pressure block up and down.

[0015] The present invention is further configured such that a switching cavity is formed at the upper end of the channel corresponding to the upper mold, and the switching cavity can be switched by the sliding mechanism by flipping up and down.

In summary, this invention has the following beneficial effects:

[0018] By using a pressure bar to press and fix the steel plate, it can be fixed to the upper surface of the upper die, thus fixing the position of the steel plate. During the corrugated groove forming process, the two sides of the steel plate are separated, and the corrugated structure portion of the steel plate is not affected by deformation. The spacing between the previous and next corrugated grooves will not be affected, resulting in better consistency in the spacing between the corrugated structures and improving the accuracy of corrugated steel plate extrusion forming. Furthermore, by using the upper and lower dies to perform extrusion forming in the width direction of the steel coil, and forming the corrugated grooves on the steel plate one by one, it is suitable for the production of steel plates with continuous multi-corrugated structures on a single sheet.

[0019] By employing a guide mechanism, rolling guide and supplementary extrusion can be achieved, thereby accurately adjusting the spacing between adjacent corrugated structures and maintaining stability during the extrusion molding process. Supplementary extrusion by the pressure block within the notch range of the corrugated bosses ensures that the bending deformation is more uniform and consistent along the entire length of the corrugated structure, improving the forming quality of the corrugated steel sheet.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This embodiment discloses a steel plate forming assembly, such as Figure 2 As shown, it includes a lower mold 1 and an upper mold 2. The lower mold 1 is mounted on the frame for fixed support. The upper mold 2 is located above the lower mold 1 and is driven to rise and fall by a hydraulic rod 3. The hydraulic rod 3 can be mounted on the upper frame. Through the driving action of the hydraulic rod 3, the upper mold 2 can be moved. Through the extrusion of the upper mold 2 and the lower mold 1, the steel plate 9 can be formed.

[0033] A corrugated groove 4 is provided on the upper end face 6 of the lower die 1, and a corrugated boss 5 is provided on the lower end face 7 of the upper die 2. The corrugated boss 5 and the corrugated groove 4 are mutually compatible and are both isosceles trapezoidal structures. Through their cooperation, a corrugated structure 91 can be formed on the steel plate 9. After one corrugated structure 91 is extruded, the steel plate 9 is continued to be conveyed for a certain distance and then processed by the upper die 2 and the lower die 1. Multiple corrugated structures 91 can be continuously processed on the steel plate 9. The steel plate 9 can be made of steel coil. Through continuous forming, a corrugated steel plate 9 can be formed. Furthermore, it can be cut according to the number of corrugations required on each steel plate 9, which is suitable for steel plate materials that require a large number of corrugations on each steel plate 9.

[0034] A through hole 10 is made on the lower end face 7 of the upper mold 2, corresponding to the side of the corrugated boss 5, as shown below. Figure 2 As shown on the right side, the through hole 10 extends vertically through the upper mold 2. A pressing rod 11 is installed inside the through hole 10. The outer diameter of the pressing rod 11 matches the inner diameter of the through hole 10, allowing the pressing rod 11 to be adjusted vertically within the through hole 10 without rotation. A hydraulic rod 12 is installed at the upper end of the pressing rod 11. The hydraulic rod 12 can be fixed to the upper frame, and its telescopic end is connected to the upper end of the pressing rod 11, enabling the lifting and lowering adjustment of the pressing rod 11. Driven by the hydraulic rod 12, the pressing rod 11 can be independently adjusted in height along with the upper mold 2. After lowering, it can press and fix the steel plate 9 onto the upper end face 6 of the upper mold 2, thereby fixing the position of the steel plate 9.

[0035] To increase the stability of clamping the steel plate 9, several through holes 10 can be opened on the right side of the upper die 2 and evenly distributed along the width of the boss. The pressure rods 11 correspond one-to-one with the through holes 10. Each pressure rod 11 together presses the steel plate 9, which can increase the stability of clamping and fixing the steel plate 9. This ensures that during the extrusion molding process, the steel plate 9 is deformed from the left side, while the corrugated structure 91 that has already been extruded on the right side is not affected.

[0036] like Figure 2 As shown, during the forming process, the steel plate 9 is conveyed from left to right. After being extruded and formed on one side, the steel plate 9 is conveyed to the right by a conveying device. The conveying distance can be adjusted according to the required spacing between the two corrugated structures 91. After the steel plate 9 is conveyed, the upper mold 2 is located on the upper side. First, the hydraulic rod 12 drives the pressure rod 11 to descend. The pressure rod 11 presses and fixes the steel plate 9 to the upper end face 6 of the lower mold 1. At this time, the processed corrugated structures 91 are all located on the right side of the pressure rod 11, while the unprocessed steel plate 9 is located on the left side. Due to the fixation of the pressure rod 11, the steel plates 9 on both sides do not affect each other. Then, the hydraulic rod 3 drives the upper mold 2 to descend. The upper mold 2 and the lower mold 1 close together, which can realize the extrusion forming of the steel plate 9. Since the left and right sides of the steel plate 9 are separated during the extrusion forming process, the right side of the steel plate 9 with the formed corrugated structure 91 is not affected by deformation, while the deformation occurs from the left side. Furthermore, since the steel plate 9 is clamped and fixed, the distance between the corrugated structure 91 produced by forming and the already formed corrugated structure 91 is determined, thus increasing the spacing between each corrugated structure 91 and improving the consistency of the formed steel plate 9.

[0037] During the forming process, the steel plate 9 mainly deforms from the left side. When the steel plate 9 is squeezed by the upper die 2 and the lower die 1, the length of the steel plate 9 between the corrugated groove 4 and the corrugated boss 5 is bent from the straight edge. The steel plate 9 needs to make up the length from the left side into the corrugated groove 4. Therefore, the steel plate 9 will move to the right between the corrugated groove 4 and the corrugated boss 5. During the movement, the steel plate 9 and the lower side of the corrugated boss 5 will generate increased friction. Excessive friction may cause surface wear on the steel plate 9. Moreover, excessive friction between the steel plate 9 and the lower side of the corrugated boss 5 will also affect the movement of the steel plate 9, generating excessive resistance, which is not conducive to the extrusion forming process of the steel plate 9.

[0038] Therefore, the above solution can be further optimized, such as... Figure 2-6As shown, a vertically penetrating channel 13 can be opened in the upper mold 2 at the position corresponding to the corrugated boss 5, and the width of the channel 13 is the same as the width of the corrugated boss 5. A guide sliding mechanism 14 is installed in the channel 13. The guide sliding mechanism 14 includes a guide pulley 141. A hydraulic rod 15 is provided on the upper part of the guide sliding mechanism 14. The hydraulic rod 15 can be installed on the upper frame, and the output end of the lower end of the hydraulic rod 15 is connected to the guide sliding mechanism 14. The hydraulic rod 15 can realize the lifting and lowering drive of the guide sliding mechanism 14. Under the driving adjustment of the hydraulic rod 15, the guide pulley 141 in the guide sliding mechanism 14 can extend downward to the lower side of the corrugated boss 5. The guide pulley 141 can protrude on the lower side of the corrugated boss 5, and can roll and guide the steel plate 9 entering between the corrugated boss 5 and the corrugated groove 4 at the lower end of the corrugated boss 5. The guide pulley 141 ensures smooth movement of the steel plate 9 between the corrugated bosses 5 and corrugated grooves 4. Before the corrugated bosses 5 and corrugated grooves 4 are fully pressed together, the guide pulley 141 can move upward and retract into the channel 13, thus not affecting the extrusion molding between the corrugated bosses 5 and corrugated grooves 4. Moreover, the steel plate 9 can also compensate for its length during the extrusion molding process through its own ductility, thus enabling molding processing.

[0039] The channel 13 within the upper die 2 extends to the lower side of the corrugated boss 5. Therefore, a short gap is formed in the width direction of the corrugated boss 5. Since the width of the gap is relatively short compared to the overall length of the corrugated boss 5, the gap has little impact on the forming effect of the corrugated structure 91 during extrusion molding. Furthermore, several sets of channels 13 are evenly arranged in the width direction of the boss, such as... Figure 5 As shown, the guide sliding mechanism 14 corresponds one-to-one with the channel 13, thereby forming a uniform multi-set guide pulley 141 structure on the lower side of the corrugated boss 5, which can maintain the conveying stability of the steel plate 9 during the guide sliding support process, making the steel plate 9 form more uniformly and stably.

[0040] like Figure 6 , 7 As shown, the guide slide mechanism 14 also includes a guide slide frame 142, a rotating shaft 143, a connecting seat 144, a pressure block 146, and a bracket 145. The guide slide frame 142 is fixedly connected to the lower part of the output end of the hydraulic rod 15, thereby supporting the various components of the guide slide mechanism 14. The rotating shaft 143 is rotatably connected to the lower end of the guide slide frame 142. The connecting seat 144 is cylindrical and is fitted and fixed on the outer periphery of the rotating shaft 143, allowing the connecting seat 144 to rotate around the rotating shaft 143.

[0041] A bracket 145 and a pressure block 146 are fixedly connected to the outer periphery of the connecting seat 144. The bracket 145 and the pressure block 146 are located on both sides of the axis at 180° to each other. A guide pulley 141 is rotatably connected to the bracket 145. There are two brackets 145 side by side, and the guide pulley 141 is rotatably connected between the two brackets 145. Figure 7 The state shown allows the guide pulley 141 and the pressure block 146 to be positioned on the upper and lower sides. By rotating the shaft 143, the guide pulley 141 and the pressure block 146 can be switched between up and down.

[0042] The contour of the pressure block 146 is adapted to the contour of the corrugated boss 5, and the shape of the lower contour is consistent with that of the lower side. When the pressure block 146 is in the downward position, with the upper mold 2 and the lower mold 1 pressed together, the pressure block 146 can supplement the downward pressure at the notch position of the corrugated boss 5, thereby enabling the extrusion forming effect in the position inside the notch. Through the supplement of the pressure block 146, the void in the notch can be reduced, thereby enabling the steel plate 9 to maintain the corrugated structure 91 more accurately and completely formed during the forming process.

[0043] Since the notch contains a pressure block 146 for supplementary compression, the width of the notch can be appropriately increased. This can be compensated by increasing the width of the guide roller 141 and the pressure block 146. Increasing the width of a single guide roller 141 can appropriately reduce the number of channels 13 and guide mechanisms 14 in the corrugated boss 5, thereby maintaining the support length of the guide roller 141 on the steel plate 9 and ensuring stable support for the steel plate 9.

[0044] like Figure 6 , 7 As shown, the connecting seat 144 is fixedly connected to the rotating shaft 143, and rotation allows the guide pulley 141 and the pressure block 146 to flip up and down. Slide grooves 131 are provided on the two sides of the channel 13 corresponding to the two ends of the rotating shaft 143, and sliders 147 are fixedly connected to both ends of the rotating shaft 143. The sliders 147 have an oblong shape, and their length direction faces the pressure block 146 and the guide pulley 141. The two sliders 147 are respectively embedded in the slide grooves 131, and the sliders 147 and slide grooves 131 are mutually guided and adapted, enabling up and down sliding guidance. Furthermore, when the sliders 147 are embedded in the slide grooves 131, it ensures that the pressure block 146 and the guide pulley 141 are always in an up-and-down state, thus positioning the guiding mechanism 14.

[0045] like Figure 2 , 3 As shown, a switching cavity 17 can be opened at the upper end of the upper mold 2 corresponding to the upper end of the channel 13. The switching cavity 17 allows the guide sliding mechanism 14 to be flipped up and down, so that the guide sliding mechanism 14 can achieve normal up and down flipping action.

[0046] like Figure 3-5 As shown, a switching mechanism 16 is provided on the upper part of the upper mold 2. The switching mechanism 16 can adjust the guide sliding mechanism 14 so that the upper and lower positions of the guide roller 141 and the pressure block 146 in the guide sliding mechanism 14 can be flipped and switched, thereby switching between guiding and pressing on the lower side of the corrugated protrusion.

[0047] The switching mechanism 16 can be driven by a servo motor and has a rotatable linkage shaft 161, which allows for 180° rotation. The linkage shafts 161 of each switching mechanism 16 can be interconnected to achieve single-motor-driven rotation, or they can be installed and arranged according to actual conditions. Furthermore, a set of switching mechanisms 16 can be installed at the upper end of a channel 13, or a set of switching mechanisms 16 can be installed at each end of the rotating shaft 143.

[0048] like Figure 4 As shown, the linkage shaft 161 is located on the upper outer side of the channel 13. The end of the linkage shaft 161 facing the channel 13 is connected to the linkage seat 162. The linkage seat 162 has a linkage groove 163 on the side facing the channel 13. The linkage groove 163 is adapted to the slider 147. The slider 147 can slide upward into the linkage groove 163.

[0049] like Figure 8 , 9 As shown, after the guide mechanism 14 is adjusted upwards, the slider 147 slides into the linkage groove 163. At this time, the rotating shaft 143 and the linkage shaft 161 are coaxial, and the two flat sides of the slider 147 cooperate with each other on the two side walls of the linkage groove 163 to form an axial rotation linkage structure. At this time, the linkage shaft 161 of the switching mechanism 16 rotates, which can drive the slider 147 and the rotating shaft 143 to rotate, and switch the guide pulley 141 and the pressure block 146 up and down.

[0050] The guide slide 142 of the guide slide mechanism 14 has an adjustable stroke. When the guide slide mechanism 14 is in the uppermost position, the slider 147 in the guide slide mechanism 14 slides into the linkage groove 163. The rotating shaft 143 is coaxial with the linkage shaft 161. Figure 8 , 9 As shown. When the guide mechanism 14 is in its lowest position, if the pressure block 146 faces downwards, the lower end of the pressure block 146 is flush with the lower end of the corrugated boss 5, as shown. Figure 10 As shown; if the guide pulley 141 faces downwards, the lower circumferential surface of the guide pulley 141 extends to the lower end of the corrugated boss 5, as shown. Figure 6As shown. By using the switching mechanism 16 to switch the pressing part of the guide sliding mechanism 14, the steel plate 9 can simultaneously achieve rolling guidance and supplementary extrusion during the forming process, thereby accurately adjusting the spacing between adjacent corrugated structures 91 and maintaining stability during the extrusion forming process; by using the pressure block 146 to supplement the extrusion within the notch range of the corrugated boss 5, the bending of the deformation along the entire length of the corrugated structure 91 can be more uniform and consistent, improving the forming quality of the corrugated steel plate 9.

[0051] This embodiment also discloses a corrugated steel sheet production equipment, including a forming component as described in the above embodiment and a steel sheet 9 conveying device. The steel sheet 9 conveying device passes the steel sheet 9 between the lower mold 1 and the upper mold 2 of the forming component. The conveyed steel sheet 9 is a steel coil. During transportation, intermittent conveying is adopted, and the work is paused during each extrusion forming process. This kind of conveying device is prior art and will not be described in detail here.

[0052] The forming component can extrude the steel plate 9 to form a uniformly arranged corrugated structure 91 on the steel plate 9. In conjunction with the conveying device, the rolled steel plate 9 is conveyed, and the steel plate 9 can be processed into a steel plate 9 with a continuous multi-corrugated structure 91. The size of the corrugated steel plate 9 can be controlled by cutting multiple steel plates 9, which is especially suitable for the production of steel plates 9 with many and wide corrugated structures 91.

[0053] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
