[0023] The following is a detailed description of a moldless roll forming servo pressing device provided by an embodiment of the present invention, with reference to the accompanying drawings.
[0024] Example:
[0025] Figure 1 This diagram shows a three-dimensional structural schematic of the dieless roll forming servo clamping device provided in an embodiment of the present invention. Figure 2 It shows Figure 1 Enlarged view of a portion of point A in the middle; Figure 3 This diagram shows another three-dimensional structural schematic of the dieless roll forming servo pressing device provided in this embodiment of the present invention; Figure 4 It shows Figure 3 Enlarged view of a portion of point B in the middle; Figure 5 This diagram illustrates a partial three-dimensional structural schematic of the dieless roll forming servo clamping device provided in an embodiment of the present invention. Figures 1 to 5As shown in the figure, the present invention provides a moldless roll forming servo clamping device, the purpose of which is to realize automatic servo clamping in the laser-assisted heating roll forming process of high-strength steel plates, realize the replacement of vulnerable parts, achieve high rolling efficiency and automation, and reduce the use of molds. The moldless roll forming servo clamping device provided in this embodiment includes: mounting base plate 1, support frame 2, servo electric cylinder 3, connecting bracket 4, upper pressure plate assembly 5, and lower pressure plate assembly 6. The support frame 2 has an "n" shaped structure and is mechanically fixed above the mounting base plate 1. The mounting base plate 1 provides stable support and installation benchmark for the entire moldless roll forming servo clamping device, ensuring installation accuracy and strong load-bearing capacity. Due to the high strength of high-strength steel (generally, the yield strength of high-strength steel is 960Mpa~1700Mpa, and the tensile strength is 980Mpa~1700Mpa), the equipment is subjected to large forces during the roll forming process of high-strength steel plates. The role of the mounting base plate 1 is crucial. The structure is relatively thick and flat; the lower pressure plate assembly 6 is set on the mounting base plate 1 to achieve its installation and fixation to support the roll forming force of the high-strength steel plate. The servo electric cylinder 3 is mechanically fixed on the support frame 2 through the connecting bracket 4. In the moldless roll forming servo clamping device provided in this utility model embodiment, two servo electric cylinders 3 and two connecting brackets 4 are used to ensure sufficient clamping force. The specific number of servo electric cylinders 3 and connecting brackets 4 can be determined according to the actual needs of the user. Here, there is no limitation on the number of servo electric cylinders 3 and connecting brackets 4. The servo electric cylinder 3 is driven to the upper end of the upper pressure plate assembly 5 through the drive shaft to realize the vertical movement of the upper pressure plate assembly 5 to clamp and release the high-strength steel plate placed on the lower pressure plate assembly 6. The upper pressure plate assembly 5 can be automatically moved up and down and the clamping force can be controlled by the servo electric cylinder 3 through the external control system. At the same time, compared with the manual method, the work efficiency is greatly improved. In addition, the use of servo electric cylinder 3 makes the control more precise.Given the high strength of high-strength steel plates, and considering that the edges of the upper pressure plate assembly 5 and the lower pressure plate assembly 6 are in direct contact with the rolled edge of the high-strength steel plates and are significantly affected by localized laser heating, the edges of the upper pressure plate assembly 5 and the lower pressure plate assembly 6 experience significant wear due to the high temperature and rolling force. After a period of use, this directly affects the rolling effect and precision of the high-strength steel plates, and the replacement cost of the upper pressure plate assembly 5 and the lower pressure plate assembly 6 is high. To address these issues, in this embodiment of the invention, a detachable upper toothed sleeve 501 is provided at the lower long edge of the upper pressure plate assembly 5 for replacement after wear. A detachable upper toothed sleeve 501 is also provided at the upper long edge of the lower pressure plate assembly 6 for replacement after wear. Replacement of the lower toothed sleeve 601 after wear; the lengths of the upper toothed sleeve 501 and lower toothed sleeve 601 are adapted to the lengths of the upper pressure plate assembly 5 and lower pressure plate assembly 6, respectively. Generally, the upper toothed sleeve 501 and lower toothed sleeve 601 are made into a slender shape for easy replacement. The length of the upper toothed sleeve 501 and lower toothed sleeve 601 is generally not less than the length of the high-strength steel plate, thereby reducing the minimum replaceable unit and saving costs. Preferably, the upper toothed sleeve 501 and lower toothed sleeve 601 are made of mold steel. The high hardness and wear resistance of mold steel reduce the replacement frequency of the upper toothed sleeve 501 and lower toothed sleeve 601, improving durability and further extending the overall service life of the moldless roll forming servo clamping device. It is economical and highly reliable.
[0026] The moldless roll forming servo clamping device provided in this embodiment of the utility model further includes, as a design improvement: a guide positioning component 7. The support frame 2 includes two parallel columns 201 and a crossbeam 202. The servo electric cylinder 3 is mechanically fixed to the crossbeam 202 through a connecting bracket 4. The two guide positioning components 7 are respectively set on the two columns 201. The sides of the upper pressure plate component 5 are slidably connected to the two guide positioning components 7 to achieve positioning and guidance when the upper pressure plate component 5 moves up and down. The guide positioning component 7 is provided with a guide rail. The two sides of the upper pressure plate component 5 can be slidably connected to the guide rail, which can accurately position and guide the upper pressure plate component 5. This prevents the upper pressure plate component 5 from shifting due to wobbling when the servo electric cylinder 3 drives the upper pressure plate component 5 to move up and down due to the long stroke. It also avoids the upper pressure plate component 5 and the lower pressure plate component 6 from shifting during clamping, further improving the rolling accuracy and effect of high-strength steel plates.
[0027] As a further design improvement, the moldless roll forming servo clamping device provided in this embodiment of the utility model also includes: a limiting roller assembly 8, a translation mechanism 10, and a servo motor 11. The limiting roller assembly 8 is provided with limiting rollers 801. The servo motor 11 is driven by the limiting roller assembly 8 through the translation mechanism 10 to realize the automatic adjustment of the distance between the two limiting rollers 801 to adapt to the feeding of high-strength steel plates of different width specifications. The limiting roller assembly 8, translation mechanism 10, and servo motor 11 are all configured in pairs. The servo motor 11 is driven by the translation mechanism 10 and the limiting roller assembly 8 to automatically adjust the distance between the two limiting rollers 801 to accommodate the feeding of high-strength steel plates of different widths. It has good adaptability. The operation of the servo motor 11 is controlled by an external control system to achieve the purpose of linear motion of the translation mechanism 10, and further drive the limiting roller assembly 8 to move linearly along the translation mechanism 10. Here, the rolling contact between the two limiting rollers 801 and the two sides of the high-strength steel plate reduces the frictional resistance during feeding. The two limiting roller assemblies 8 can also adjust the position and posture of the high-strength steel plate to ensure the accuracy of feeding. It is worth noting that the feeding of high-strength steel plates can be carried out manually or automatically by industrial robots or intelligent robots. This utility model embodiment can adapt to the above feeding methods.
[0028] As a further design improvement, the moldless roll forming servo clamping device provided in this embodiment of the utility model also includes: a rolling base plate 9, a plurality of rolling base plates 9 are disposed on the mounting base plate 1, and the rolling base plate 9 is provided with a plurality of ball bearing assemblies 901 to facilitate the feeding of high-strength steel plates. The ball bearing assembly 901 is provided with balls, which can roll freely in the ball bearing assembly 901 without falling off. Generally, the width of the setting area of the rolling base plate 9 is generally larger than the width of the high-strength steel plate, which makes it easier to make full use of the rolling contact between the high-strength steel plate and the ball bearing assembly 901 in the rolling base plate 9, greatly reducing the feeding friction resistance of the high-strength steel plate.
[0029] In a moldless roll forming servo clamping device provided in this embodiment of the utility model, as a further design improvement, the highest point of the ball assembly 901 and the top surface of the lower tooth sleeve 601 are located in the same plane to ensure the horizontal state of the high-strength steel plate, thereby achieving stable feeding and avoiding tilting to reduce the rolling accuracy.
[0030] In a moldless roll forming servo clamping device provided in this embodiment of the utility model, as a further design improvement, the connecting bracket 4 is provided with guide rods 401. The guide rods 401 are symmetrically arranged about the drive shaft of the servo electric cylinder 3. Generally, two guide rods 401 are provided on each connecting bracket 4. The symmetrical distribution ensures the smoothness and uniform force of the drive shaft of the servo electric cylinder 3 on the upper pressure plate assembly 5, and prevents shaking caused by the long stroke of the drive shaft of the servo electric cylinder 3, thereby further improving the smoothness and accuracy of the movement of the upper pressure plate assembly 5.
[0031] Compared with the prior art, the moldless roll forming servo clamping device provided in this embodiment of the utility model is reasonably designed. It realizes automatic clamping of high-strength steel plate roll forming process through servo electric cylinder 3 and servo motor 11. The use of replaceable upper tooth sleeve 501 and lower tooth sleeve 601 improves the overall service life of the moldless roll forming servo clamping device, greatly reduces replacement costs, has high rolling efficiency and automation, reduces the use of molds, has good economy, adaptability and versatility, operates accurately and reliably, improves work efficiency, and meets the specific needs of users.
