Description

Technical Field

[0001] This invention belongs to the field of metal strip rolling technology, specifically relating to a lead strip connection structure and method for solving the problem that it is impossible to spot weld the lead strip during strip rolling. Background Technology

[0002] Currently, in the metal strip rolling process, the distance between the rolling drum and the rolls is 3-5 meters. When processing metal materials with relatively high raw material prices (such as gold foil, silver foil, high-purity aluminum, copper, etc.), in order to save materials and avoid waste, a lead strip needs to be welded to both ends of the metal material. The commonly used welding method is to overlap the lead strip with the metal to be rolled and then directly spot weld them together using a spot welding machine. However, some metals (such as high-purity copper, high-purity aluminum, metal-based compound materials and their alloys, and ultra-thick metal strips, which are not easily spot welded) are not easy or cannot be spot welded to the lead strip. Therefore, the common practice is to rivet or directly use the rolled metal itself as the lead strip. However, when using the former connection method, the protruding parts of the rivets are prone to damaging the rolled metal material during the rolling process and are not secure. On the other hand, using the rolled metal itself as the lead strip increases costs and wastes metal materials. Therefore, it is necessary to carry out technical research to address the above problems. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a lead strip connection structure and method for solving the problem of spot welding the lead strip during strip rolling. By marking positioning indentations on both ends of the pressure plate and the rolled metal strip, and setting welding holes on the rolled metal strip, the pressure plate is spot welded to the lead strip through the welding holes at both ends of the rolled metal strip using a spot welding machine. This clamps the rolled metal, fixing both ends of the rolled metal strip to the lead strip as a single unit. This solves the rolling problem of not being able to directly weld the lead strip to the rolled metal strip. The connection structure, which allows the pressure plate to be directly spot welded to the lead strip and clamp the rolled metal strip through the welding holes at both ends of the rolled metal strip, saves materials, reduces costs, and features a novel, reliable, and robust connection structure with high practical value.

[0004] The technical solution adopted in this invention is a lead strip connection structure for solving the problem of spot welding of lead strips during strip rolling. It includes a rolled metal strip, lead strips and pressure plates at both ends of the rolled metal strip. The pressure plates, the ends of the rolled metal strip and the lead strips are stacked sequentially from top to bottom. The surface of the rolled metal strip ends has welding holes corresponding to the positions of the positioning marks on the pressure plates. The lead strips and pressure plates are welded and fixed together through the welding holes via the positioning marks, thereby realizing the fixed connection between the two ends of the rolled metal strip and the corresponding lead strips.

[0005] The rolled strip has multiple welding holes on its metal end face.

[0006] Furthermore, the guide strip and the pressure plate have the same width.

[0007] Furthermore, the diameter of the welding hole ranges from φ0.1 to φ50 mm.

[0008] A method for connecting lead strips to address the inability to spot weld lead strips during strip rolling includes the following steps:

[0009] 1) Prepare materials: Prepare the rolled metal strip, lead strip, and pressure plate to be rolled;

[0010] 2) Stack the pressure plate and the ends of the rolled metal strip on top of each other, and press positioning marks on the stacked pressure plate and rolled metal strip.

[0011] 3) Next, weld holes of φ0.1-φ50mm are machined at the positions marked on the rolled metal strip;

[0012] 4) Set a pressure plate at the upper surface of the rolled metal strip end, and make the positioning marks on the pressure plate correspond to the welding hole position. Set a guide belt at the lower surface of the rolled metal strip end, so that the pressure plate, rolled metal strip and guide belt are stacked from top to bottom.

[0013] 5) Using the contact of a spot welding machine, the pressure plate and the lead strip are welded together through the positioning marks on the pressure plate and the welding holes at the end of the rolled metal strip, thus completing the fixed connection between the end of the rolled metal strip and the lead strip.

[0014] Advantages of this invention compared to existing technologies:

[0015] 1. This technical solution marks the ends of the pressure plate and the rolled metal strip with positioning marks and indentations, and sets welding holes on the rolled metal strip. The pressure plate is then spot-welded to the lead strip through the welding holes at both ends of the rolled metal strip using a spot welding machine, thereby clamping the rolled metal and fixing both ends of the rolled metal strip to the lead strip as one unit. This solves the rolling problem where the lead strip cannot be directly welded to the rolled metal strip.

[0016] 2. This technical solution uses welding holes at both ends of the rolled metal strip to directly spot weld the pressure plate and the lead strip to clamp the rolled metal strip, which saves materials, reduces costs, and the connection structure design is novel, reliable and strong.

[0017] 3. This technical solution eliminates the drawbacks of rivet protrusions damaging the rolled metal material and weak connection when riveting the rolled metal strip to the guide strip. It eliminates the need to use the rolled metal itself as the guide strip, and the connection structure is simple and easy to follow. It is firmly and reliably fixed and has high application value and widespread applicability. Attached Figure Description

[0023] The following will be based on embodiments of the present invention. Figure 1-5 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In this document, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0026] A lead-in strip connection structure used to solve the problem of spot welding the lead-in strip during strip rolling, such as Figure 1-5As shown, it includes a rolled metal strip 1, guide strips 2 located at both ends of the rolled metal strip 1, and a pressure plate 3. The pressure plate 3, the ends of the rolled metal strip 1, and the guide strips 2 are stacked sequentially from top to bottom, as shown. Figure 2 The structure is presented in three layers (top, middle, and bottom), but can also be multi-layered depending on the situation. The end surface of the rolled metal strip 1 has welding holes 4 corresponding to the positions of the positioning marks 6 on the pressure plate 3. The lead strip 2 and the pressure plate 3 are welded together through the positioning marks 6 and the welding holes 4, thus achieving a fixed connection between the two ends of the rolled metal strip 1 and the corresponding lead strip 2. In the above structure, by setting welding holes 4 at the ends of the rolled metal strip 1, the pressure plate 3, the rolled metal strip, and the lead strip 2 stacked on the top and bottom are fixedly connected as one unit by the contact of a spot welding machine through the positioning marks 6 on the pressure plate 3 and the welding holes 4 on the rolled metal strip 1, solving the rolling problem that the lead strip 2 cannot be directly welded to the rolled metal strip 1.

[0027] The rolled metal strip 1 has multiple welding holes 4 on its end surface, which can be circular, square, or other shapes. Specifically, the width of the guide strip 2 and the pressure plate 3 is the same, but not necessarily the same as the width of the rolled metal strip 1. Specifically, the diameter of the welding holes 4 ranges from φ0.1 to φ50 mm.

[0028] A method for connecting lead strips to address the inability to spot weld lead strips during strip rolling includes the following steps:

[0029] 1) Prepare materials: Prepare the rolled metal strip 1, the guide strip 2, and the pressure plate 3 to be rolled;

[0030] 2) Stack the ends of the pressure plate 3 and the rolled metal strip 1 on top of each other, and press out multiple positioning mark marks 6 on the stacked pressure plate 3 and the rolled metal strip 1.

[0031] 3) Next, weld holes 4 with a diameter of φ0.1-φ50mm are machined at the positioning mark 6 position on the rolled metal strip 1. This method is beneficial to the correspondence between the multiple positioning mark 6 on the pressure plate 3 and the weld holes 4 on the rolled metal strip 1, so as to facilitate spot welding positioning. The diameter and number of weld holes 4 are determined according to the width and thickness of the rolled metal strip 1. The thicker the rolled metal strip 1, the larger the diameter of the weld holes 4; the wider the rolled metal strip 1, the more weld holes 4 are required.

[0032] 4) A pressure plate 3 is set at the upper strip surface position of the end of the rolled metal strip 1, and the positioning mark 6 on the pressure plate 3 corresponds to the position of the welding hole 4. A guide belt 2 is set at the lower strip surface position of the end of the rolled metal strip 1, so that the pressure plate 3, the rolled metal strip 1 and the guide belt 2 are stacked from top to bottom.

[0033] 5) Using the spot welding machine contact 5, the pressure plate 3 and the guide strip 2 are welded together through the positioning mark 6 on the pressure plate 3 and the welding hole 4 at the end of the rolled metal strip 1, thus completing the fixed connection between the end of the rolled metal strip 1 and the guide strip 2.

[0034] This technical solution uses welding holes 4 at both ends of the rolled metal strip 1 to directly spot weld the pressure plate 3 and the guide strip 2 to clamp the rolled metal strip 1, saving materials and reducing costs. The connection structure design is novel, reliable and strong. It eliminates the disadvantages of rivet protrusions damaging the rolled metal material and weak connection when riveting the rolled metal strip 1 and the guide strip 2. It does not require the rolled metal strip 1 itself to be used as the guide strip. The connection structure is simple and easy to follow, and the fixation is firm and reliable. It has high application value and popularity.
