Technical Field

[0001] This utility model relates to the field of thin strip steel breakage connection technology, and in particular to an auxiliary tooling for connecting thin strip steel breakage on a continuous production line. Background Technology

[0002] During maintenance and accident handling of the cold-rolled strip continuous annealing production line, it is necessary to cut the strip from the middle of the equipment to facilitate equipment maintenance. After the equipment maintenance is completed, the ends of the cut strip need to be joined together, and square holes need to be cut on the strip for folding and welding. Before cutting, manual measurement and marking are required before cutting the square holes.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The purpose of this invention is to provide an auxiliary tooling for connecting broken thin strip steel on a continuous production line, so as to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively improves the accuracy of marking and positioning when connecting broken thin strip steel, and effectively improves work efficiency.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] This utility model provides an auxiliary tooling for connecting broken strips of thin steel on a continuous production line, such as... Figures 1-3 As shown, it includes: a scribing template 10, a hook 11, a first clamping fastener, a second clamping fastener, and a driving component 13. The scribing template 10 is evenly provided with multiple cross-shaped scribing grooves 12. The hook 11 is fixedly connected to the middle of the top surface of the scribing template 10 for connection with lifting equipment. The first clamping fastener is slidably connected to one end of the bottom of the scribing template 10. The second clamping fastener is slidably connected to the other end of the bottom of the scribing template 10. The driving component 13 is used to drive the first clamping fastener and the second clamping fastener to move synchronously towards each other to clamp and fix the thin strip steel, providing a complete auxiliary tooling structure frame for connecting broken strip steel. The cross-shaped scribe groove 12 facilitates accurate scribe marking and determines the cutting position; the hook 11 facilitates the tooling to be switched between different working positions, reducing the impact on the normal operation of the production line; the sliding first clamping and fixing parts and the second clamping and fixing parts cooperate with the drive part 13 to achieve fast and accurate clamping and positioning of thin strip steel, thereby avoiding the inaccuracy and inefficiency of traditional manual positioning, improving work efficiency and accuracy, and shortening maintenance time.

[0026] In a preferred embodiment, the first clamping fastener includes a first support plate 18 and a first clamping positioning plate 17. The first support plate 18 is vertically fixedly connected to the bottom end of the first clamping positioning plate 17 near the side of the second clamping fastener to support and clamp one side of the thin strip steel. This structural design of the first support plate 18 and the first clamping positioning plate 17 allows the first clamping fastener to not only position the thin strip steel but also provide effective support. The vertically fixed structure ensures stability during the clamping process, preventing the thin strip steel from tilting or shaking during clamping, further improving clamping accuracy, providing a good foundation for subsequent precise marking and welding work, and contributing to improved product quality.

[0027] In a preferred embodiment, the second clamping fastener includes a second support plate 21 and a second clamping positioning plate 20. The second support plate 21 is vertically fixedly connected to the bottom end of the second clamping positioning plate 20 near the side of the first clamping fastener to support and clamp the other side of the thin strip steel. Similar to the first clamping fastener, this structural design of the second clamping fastener achieves stable support and clamping from the other side of the thin strip steel. In conjunction with the first clamping fastener, the thin strip steel can be firmly clamped from both sides, preventing displacement during processing and ensuring the positional accuracy of the thin strip steel. This allows for more precise scribing and welding operations, reducing hole position deviations and welding quality problems caused by changes in the position of the thin strip steel, and improving the overall quality of the thin strip steel breakage connection.

[0028] In a preferred embodiment, the driving component 13 includes a first support plate, a second support plate, and a bidirectional lead screw. The top end of the first support plate is vertically fixedly connected to one end of the scribing template 10, and the top end of the second support plate is vertically fixedly connected to the other end of the scribing template 10. The two ends of the bidirectional lead screw are rotatably connected to the first and second support plates, respectively, and are threadedly connected to the first clamping positioning plate 17 and the second clamping positioning plate 20, respectively, and can drive the first and second clamping positioning plates 17 and 20 to move synchronously closer or further away. The first and second support plates provide stable support for the bidirectional lead screw, ensuring its stability during rotation. The threaded connection between the bidirectional lead screw and the clamping positioning plates can precisely control the synchronous movement of the first and second clamping positioning plates 20, achieving precise centering and clamping of the thin strip steel. Compared with the traditional manual adjustment method, this greatly improves the clamping accuracy and work efficiency, ensuring that the position of the thin strip steel is highly consistent each time, thereby improving the quality and stability of the entire strip breaking and connection operation.

[0029] In a preferred embodiment, the bidirectional lead screw includes a coaxially integrated positive lead screw 15 and a negative lead screw 16. A first clamping positioning plate 17 has a first threaded hole, with the positive lead screw 15 threadedly connected to it. A second clamping positioning plate 20 has a second threaded hole, with the negative lead screw 16 threadedly connected to it. The coaxially integrated positive and negative lead screws 15 and 16 have a compact design. By engaging with the corresponding threaded holes on the first and second clamping positioning plates 17 and 20, they can precisely control the opposing or reversing movements of the first and second clamping positioning plates 17 and 20 under the same driving source (such as the adjusting knob 14 or drive motor mentioned later). When the positive and negative lead screws 15 and 16 rotate synchronously, it ensures that the first and second clamping positioning plates 17 and 20 move closer or further away at the same speed, thereby achieving accurate and stable clamping operation on thin strip steel, further improving clamping precision and consistency, and facilitating the stable operation of subsequent processes.

[0030] In a preferred embodiment, the driving component 13 further includes a limiting guide rod 19, which is arranged parallel to the bidirectional lead screw. The first clamping positioning plate 17 is provided with a first through hole, and the second clamping positioning plate 20 is provided with a second through hole corresponding to the first through hole. The two ends of the limiting guide rod 19 pass through the first through hole and the second through hole, respectively, and are fixedly connected to the first support plate and the second support plate. The setting of the limiting guide rod 19 provides accurate guidance for the first clamping positioning plate 17 and the second clamping positioning plate 20 during movement. By being arranged parallel to the bidirectional lead screw and cooperating with the through holes on the clamping positioning plates, the movement direction of the clamping positioning plates is limited, preventing them from deviating or shaking during the lead screw drive. This further improves the smoothness and accuracy of the movement of the first and second clamping positioning plates 20, ensuring the positional stability of the thin strip steel during the clamping process, thereby improving the positioning accuracy of the entire auxiliary tooling for the thin strip steel, and providing a more reliable guarantee for accurate scribing and reliable welding.

[0031] In a preferred embodiment, the drive component 13 further includes an adjustment knob 14, which is fixedly connected to the end of the positive lead screw 15 extending out of the first support plate. The adjustment knob 14 provides the operator with a convenient control component. By rotating the adjustment knob 14, the rotation of the positive lead screw 15 can be directly controlled, thereby driving the negative lead screw 16 to rotate synchronously, realizing the adjustment of the position of the first and second clamping positioning plates 20. This manual adjustment method is simple and intuitive to operate. The operator can accurately control the clamping degree of the thin strip steel according to actual needs, and adapt to the differences in thickness, width and other dimensions of different thin strip steels in real time, improving the versatility of the tooling and the convenience of operation.

[0032] In a preferred embodiment, the drive unit 13 further includes a drive motor. The housing of the drive motor is fixedly connected to the first support plate, and the output shaft of the drive motor is coaxially fixedly connected to the lead screw 15. The introduction of the drive motor automates the driving process. Compared to manual adjustment, the drive motor can provide a more stable and precise power output, ensuring that the lead screw 15 rotates at a stable speed and torque, thereby making the movement of the first clamping positioning plate 17 and the second clamping positioning plate 20 smoother and more precise. At the same time, automated driving can reduce human error, improve work efficiency, and is suitable for large-scale, repetitive thin strip steel breaking and joining operations, improving the automation level and quality stability of the entire production process.

[0033] The following is a method for using an auxiliary tooling for joining broken thin strip steel on a continuous production line:

[0034] Preparation

[0035] Inspection of tooling: Before use, carefully inspect all parts of the auxiliary tooling to ensure they are intact. Check for cracks or deformation in the scribing template 10; whether the hook 11 can be properly engaged and is free from obvious wear; whether the connections of the first and second clamping fasteners are secure; whether the lead screw of the drive component 13 rotates smoothly; whether the limit guide rod 19 is securely installed; whether the adjusting knob 14 rotates flexibly; and whether the drive motor (if equipped) is operating normally, etc.

[0036] Positioning of hoisting fixture: Using hoisting equipment, hook the auxiliary fixture to the top of the fixture and hoist it to the work position where the thin strip steel broken strip needs to be connected. Gently place it above the thin strip steel broken strip connection point, ensuring that the marking template 10 of the fixture covers the connection part and the whole is in a stable state.

[0037] Clamping thin strip steel

[0038] Manual adjustment method (using adjustment knob 14)

[0039] Rotate adjustment knob 14: If the adjustment knob 14 is used for operation, the operator manually rotates the adjustment knob 14, which drives the positive lead screw 15 to rotate.

[0040] Driven by lead screws: When the positive lead screw 15 rotates, the coaxial negative lead screw 16 also rotates synchronously. Since the positive lead screw 15 is threadedly connected to the first clamping positioning plate 17, and the negative lead screw 16 is threadedly connected to the second clamping positioning plate 20, and the limiting guide rod 19 provides guidance and limitation for the first and second clamping positioning plates 20, during the rotation of the lead screws, the first and second clamping positioning plates 20 will move synchronously towards each other along the limiting guide rod 19.

[0041] Clamping complete: As the adjustment knob 14 continues to rotate, the first and second clamping positioning plates 20 gradually approach the thin strip steel. When they approach the thin strip steel, the knob is finely adjusted until the first support plate 18 and the second support plate 21 firmly support and clamp the thin strip steel from both sides, thus achieving precise centering and clamping of the thin strip steel.

[0042] Automatic adjustment method (using a drive motor)

[0043] Start the drive motor: If a drive motor is provided, turn on the power to start the drive motor. The output shaft of the drive motor will drive the lead screw 15 to rotate.

[0044] The positive lead screw 15 rotates, causing the coaxial negative lead screw 16 to rotate synchronously, so that the first and second clamping positioning plates 20 move synchronously towards each other along the limit guide rod 19, realizing the automatic clamping operation of the thin strip steel. The clamping situation also needs to be observed and appropriate adjustments made if necessary.

[0045] Line drawing operation

[0046] Once the thin strip steel is securely clamped, the operator uses a specialized scribing tool to mark the surface of the thin strip steel along the evenly spaced cross-shaped grooves 12 on the scribing template 10, according to the actual cutting requirements. These cross-shaped grooves 12 provide a precise reference for the scribing operation, ensuring the accuracy and consistency of the scribing.

[0047] Follow-up processing

[0048] Cutting and welding preparation: Cut the thin strip steel according to the marked lines, dividing the square hole into four triangles along the diagonal. Then, fold the four square areas outwards to complete the folding, preparing for welding.

[0049] Welding and fixing: Using appropriate welding technology and equipment, the folded triangle is spot welded to the thin strip steel to complete the splicing and preliminary reinforcement of the broken ends of the thin strip steel, so that the thin strip steel can be reconnected into a whole at the break point.

[0050] Finishing touches: After welding, wrap the overlapping areas with strong adhesive tape to further protect and reinforce the welded parts, preventing them from loosening or being damaged by external factors during subsequent transport of the thin strip steel. Then, use hoisting equipment to lift the auxiliary tooling to a suitable storage location via hook 11 for future use.

[0051] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
