Description

Technical Field

[0001] This utility model relates to the field of stainless steel strip processing technology, and in particular to a multi-roll cold rolling forming equipment for irregular cross-section stainless steel strips. Background Technology

[0002] In modern industrial production, stainless steel strip is widely used in many fields such as building decoration, machinery manufacturing, and electronics due to its excellent corrosion resistance, high strength and good processing performance. With the continuous growth of demand for stainless steel strip products in various industries, higher requirements are also being placed on the cross-sectional shape and dimensional accuracy of stainless steel strip.

[0003] Cold rolling is an important process in stainless steel strip processing. By rolling and deforming stainless steel strips, the desired cross-sectional shape and size can be obtained. However, existing stainless steel strip cold rolling forming equipment has many shortcomings when processing stainless steel strips with irregular cross-sections. On the one hand, traditional equipment has poor side positioning effect on stainless steel strips, making it difficult to adapt to stainless steel strips of different widths. During the cold rolling process, the stainless steel strip is prone to deviation, which cannot guarantee the dimensional accuracy of the product. On the other hand, the adjustment flexibility of the cold rolling forming mechanism is insufficient, making it difficult to quickly and accurately adjust the roll spacing. This makes it impossible to meet the processing needs of stainless steel strips with irregular cross-sections of different specifications and shapes, resulting in insufficient practicality. Therefore, it is necessary to redesign multi-roll cold rolling forming equipment for stainless steel strips with irregular cross-sections to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-roll cold rolling forming equipment for stainless steel strips with irregular cross-sections.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-roll cold rolling forming machine for irregular cross-section stainless steel strip includes a support base. Two support plates are fixedly installed inside the support base, and a pressure plate is fixedly installed on the upper surface of both support plates. Electric push rods are fixedly installed on both outer walls of the support base via mounting frames. Telescopic openings that mate with the telescopic ends of the electric push rods are provided on both outer walls of the support base. Positioning frames are fixedly installed on the telescopic ends of both electric push rods. Multiple positioning rollers are rotatably installed inside each of the two positioning frames. A hydraulic cylinder is fixedly installed on the upper surface of the support base via a mounting plate. A connecting frame is fixedly installed on the telescopic end of the hydraulic cylinder. A bidirectional screw is rotatably installed inside the connecting frame. A second motor connected to the bidirectional screw is fixedly installed on the outer wall of the connecting frame. Two moving blocks are threadedly installed on the outer wall of the bidirectional screw via a limiting mechanism. Rollers are rotatably installed on the bottom walls of both moving blocks via connecting frames. A third motor connected to the rotation shaft of the corresponding roll is fixedly installed on the outer wall of one of the connecting frames.

[0007] Preferably, the limiting mechanism includes two limiting rods fixedly installed inside the connecting frame, and both limiting rods slide through the two moving blocks.

[0008] Preferably, a connecting plate is fixedly installed on the upper surface of the support base, and two downward pressure rods are slidably installed through the upper surface of the connecting plate, with one end of each of the two downward pressure rods being fixedly connected to a connecting plate.

[0009] Preferably, each of the two pressure rods is equipped with a pressure spring on its outer wall, and the two ends of the two pressure springs are elastically connected to the upper surface of the connecting plate and the bottom of the connecting plate, respectively. The other end of the two pressure rods is fixedly connected to a pressure frame.

[0010] Preferably, a feeding roller is rotatably installed inside the lower pressure frame, a first motor connected to the rotating shaft of the feeding roller is fixedly installed on the outer wall of the lower pressure frame, and multiple anti-slip blocks are fixedly installed on the outer wall of the feeding roller.

[0011] Preferably, two stabilizing rods are fixedly installed on the upper end face of the connecting frame, and both stabilizing rods slide through the mounting plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as electric push rods, positioning frames, and positioning rollers, the positioning frames can be moved by electric push rods according to the width of the stainless steel strip before cold rolling, and the position of the positioning rollers can be flexibly adjusted. The positioning rollers accurately fit the two sides of the steel strip, stably guide the positioning, ensure the straight running of the steel strip, avoid deviation, improve the cold rolling processing accuracy and quality stability, and reduce material waste and equipment wear.

[0014] 2. By setting up components such as a bidirectional screw, a limiting rod, and a moving block, the second motor drives the bidirectional screw to rotate. Under the limiting action of the limiting rod, the moving block can move stably along the axial direction of the bidirectional screw, thereby precisely adjusting the distance and position between the two rolls. This flexible adjustment method enables the equipment to quickly adapt to the processing needs of various irregular cross-section stainless steel strips. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A multi-roll cold rolling forming machine for stainless steel strip with irregular cross-section includes a support base 1. Two support plates 2 are fixedly installed inside the support base 1. A pressure plate 3 is fixedly installed on the upper surface of both support plates 2. Electric push rods 5 are fixedly installed on both outer walls of the support base 1 via mounting frames 4. Telescopic openings that mate with the telescopic ends of the electric push rods 5 are provided on both outer walls of the support base 1. Positioning frames 6 are fixedly installed on the telescopic ends of both electric push rods 5. Multiple positioning rollers 7 are rotatably installed inside both positioning frames 6. The upper surface of the support base 1 is connected via... A hydraulic cylinder 17 is fixedly mounted on the mounting plate 16. A connecting frame 18 is fixedly mounted on the telescopic end of the hydraulic cylinder 17. A bidirectional screw 20 is rotatably mounted inside the connecting frame 18. A second motor 21 connected to the bidirectional screw 20 is fixedly mounted on the outer wall of the connecting frame 18. Two moving blocks 23 are threadedly mounted on the outer wall of the bidirectional screw 20 through a limiting mechanism. Rollers 25 are rotatably mounted on the bottom walls of the two moving blocks 23 through a connecting frame 24. A third motor 26 connected to the rotating shaft of the corresponding roller 25 is fixedly mounted on the outer wall of one of the connecting frames 24.

[0024] The limiting mechanism includes two limiting rods 22 fixedly installed inside the connecting frame 18, and both limiting rods 22 slide through the two moving blocks 23.

[0025] Furthermore, the limit rod 22 is made of high-strength alloy material, which has good wear resistance and deformation resistance. Even under long-term and high-load operation, it can still accurately limit the movement trajectory of the moving block 23, preventing it from deviating or shaking when the bidirectional screw 20 rotates. This ensures that the spacing adjustment of the two rolls 25 is more precise and stable, thereby effectively improving the dimensional accuracy of cold rolling of stainless steel strip.

[0026] A connecting plate 8 is fixedly installed on the upper surface of the support base 1. Two downward pressure rods 9 are slidably installed through the upper surface of the connecting plate 8. One end of each of the two downward pressure rods 9 is fixedly connected to a connecting plate 10.

[0027] Furthermore, a high-precision linear bearing is provided at the sliding connection between the lower pressure rod 9 and the connecting plate 8, which greatly reduces the friction when the lower pressure rod 9 slides up and down, making the lifting and lowering process of the lower pressure rod 9 smoother.

[0028] Both pressure rods 9 are equipped with pressure springs 11 on their outer walls. The two ends of the two pressure springs 11 are elastically connected to the upper end face of the connecting plate 8 and the bottom of the connecting plate 10, respectively. The other end of the two pressure rods 9 is fixedly connected to a pressure frame 12.

[0029] Furthermore, the compression spring 11 is made of spring material with high elastic coefficient and stable elastic performance. Through its elastic action, it can not only ensure that the feeding roller 13 and the stainless steel strip always maintain a suitable clamping force to prevent slippage, but also adapt to stainless steel strips of different hardness and materials, so as to achieve stable and efficient feeding without damaging the surface of the steel strip.

[0030] The lower pressure frame 12 has a feeding roller 13 rotatably mounted inside it. The outer wall of the lower pressure frame 12 is fixedly mounted with a first motor 14 connected to the rotating shaft of the feeding roller 13. The outer wall of the feeding roller 13 is fixedly mounted with multiple anti-slip blocks 15.

[0031] Furthermore, the anti-slip block 15 is made of rubber with a special anti-slip texture on its surface, which can significantly increase the friction between it and the stainless steel strip.

[0032] Two stabilizing rods 19 are fixedly installed on the upper end face of the connecting frame 18, and both stabilizing rods 19 slide through the mounting plate 16.

[0033] Furthermore, the diameter of the stabilizer bar 19 forms a precise sliding fit with the through hole on the mounting plate 16, and long-lasting grease is applied to the contact surface to effectively reduce sliding friction. In addition, limit flanges are provided at both ends of the stabilizer bar 19 to prevent the connecting frame 18 from detaching from the mounting plate 16 during vertical movement, further enhancing the stability of the connecting frame 18 during cold rolling and ensuring the accuracy and reliability of the rolling mill roll 25 on the stainless steel strip.

[0034] When using this invention, the end of the stainless steel strip can be placed between the upper surface of the pressure plate 3 and the feeding roller 13. The first motor 14 is started, and the feeding roller 13 starts to rotate under the drive of the motor. The stainless steel strip is smoothly conveyed upward by the friction between the anti-slip block 15 on its outer wall and the stainless steel strip. At the same time, the lower pressure spring 11 applies elastic pressure to the lower pressure frame 12 through the lower pressure rod 9, so that the feeding roller 13 can closely fit the stainless steel strip, further ensuring the stability of the feeding process and preventing the stainless steel strip from slipping or deviating during the conveying process. When the stainless steel strip is conveyed to the positioning frame 6, the electric push rod 5 is started according to the width of the stainless steel strip. The telescopic end of the electric push rod 5 drives the positioning frame 6 to move horizontally and adjust the position of multiple positioning rollers 7 so that the positioning rollers 7 can accurately fit the two sides of the stainless steel strip, thereby performing side positioning and guidance of the stainless steel strip, ensuring that the stainless steel strip keeps running in a straight line during the subsequent cold rolling process and does not deviate.

[0035] After loading and positioning are completed, the hydraulic cylinder 17 is started. By adjusting the height of the connecting frame 18, the rolling distance and pressure between the roll 25 and the stainless steel strip are initially determined. Then, the second motor 21 is started to drive the bidirectional screw 20 to rotate. Under the limiting action of the two limit rods 22, the two moving blocks 23 move along the axial direction of the bidirectional screw 20, thereby adjusting the distance and position between the two rolls 25 to meet the shape requirements of the stainless steel strip with irregular cross-section to be processed. After everything is ready, the third motor 26 is started to drive the roll 25 to rotate. Under the rotation action of the roll 25, the stainless steel strip is gradually rolled into the required irregular cross-sectional shape. During the cold rolling process, the extension and retraction of the hydraulic cylinder 17 and the rotation angle of the bidirectional screw 20 can be flexibly adjusted according to the actual processing effect to fine-tune the position and pressure of the roll 25 to achieve ideal forming accuracy and quality.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
