Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery manufacturing, and specifically relates to a quick-connect device for lead mesh. Background Technology

[0002] In lead mesh production, raw lead strips are fed into a continuous punching machine to be punched into lead mesh. The finished lead mesh is then wound up by a winding machine and stored for later use. Because the lead strip loses 70% of its weight during punching, the weight of the lead mesh decreases significantly. Since the load-bearing capacity of the lead mesh winding machine is the same as that of the lead strip winding machine, the length of the wound lead mesh of the same weight is greater than that of the lead strip. Therefore, during the punching process, the lead mesh produced from each roll of lead strip needs to be connected before continuing to wind up to ensure continuity. Currently, lead mesh is mostly connected using snap-fit ​​connections or manual welding. Snap-fit ​​connections involve cutting and polishing the joint between the two sections of lead mesh to be connected, then using upper and lower snap-fits to connect the two sections before continuing to wind up. The disadvantages are: the snap-fit ​​gets stuck inside the lead mesh after winding up, affecting the shape of the lead mesh and increasing scrap in subsequent processes; cutting and polishing the lead mesh before using snap-fits is time-consuming and wasteful, affecting the production rhythm. Welding involves completely cutting and grinding the joint of the two sections of lead mesh to be connected, and then using a welding machine to weld the two sections of lead mesh together. Its disadvantages are: complete cutting results in a large waste of lead mesh, increasing scrap, and grinding the lead mesh before welding is time-consuming, affecting the production rhythm. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and provide a quick lead mesh connection device that is simple to operate and has high connection efficiency.

[0004] The technical solution adopted by this utility model is as follows: a quick connection device for lead mesh, including a base plate; a receiving groove for placing a lead mesh mold is provided in the middle of the base plate; clamping mechanisms are provided on both sides of the receiving groove on the base plate for clamping two sections of lead mesh to be connected so that their end grid units overlap on the lead mesh mold in the receiving groove; the clamping mechanism includes an upper pressure plate and a vertical clamp for driving the upper pressure plate to press down / lift to clamp / release the lead mesh; the base of the vertical clamp is mounted on the base plate, and the front end of the pressure rod is connected to the upper pressure plate;

[0005] The shape of the lead mesh mold cavity is the same as that of 2-3 complete grid units on the lead mesh; it also includes a heating plate that works with the lead mesh mold to melt the ends of the two lead mesh sections and form them into 2-3 complete grid units so that the two lead mesh sections are connected as a whole, and a lifting mechanism for driving the heating plate to rise / fall.

[0006] The lead mesh mold is provided with a lead molten overflow port, and the bottom plate is provided with a lead molten discharge hole that is connected to the lead molten overflow port.

[0007] It also includes a lead liquid collection box that is movably connected to the lower part of the base plate for collecting lead liquid discharged through the lead liquid discharge hole.

[0008] The base plate has a mounting groove for installing a lead liquid collection box, which is movably inserted into the mounting groove.

[0009] The lead mesh mold is equipped with a cooling water inlet and a cooling water outlet.

[0010] It also includes a pad for placing under the lead wire mold in the receiving groove to adjust the height of the lead wire mold.

[0011] It also includes a double-button foot switch for controlling the lifting mechanism to raise or lower the heating plate.

[0012] The heating plate is connected to the lifting mechanism via a fixed seat; the lower surface edge of the fixed seat is matched with the limiting part at the outer edge of the receiving groove on the upper surface of the base plate for limiting.

[0013] The lifting mechanism includes a hydraulic cylinder; the fixed base includes a fixing plate for fixing the heating plate and a connecting rod for fixing the fixing plate to the outer end of the piston rod of the hydraulic cylinder.

[0014] Compared with the existing technology, the advantages of this utility model are: 1. It uses die casting to connect two sections of lead mesh, eliminating the need for cutting and grinding, thus reducing the scrap rate; 2. It improves the production pace; 3. At the same time, the connection does not affect the production of subsequent processes. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of this utility model.

[0016] Figure 2 for Figure 1 Top view. Detailed Implementation

[0017] like Figure 1 , Figure 2 As shown, the quick-connect device for lead mesh provided by this utility model includes a base plate 1 and a support column 11. A receiving groove 100 for placing a lead mesh mold 8 is provided in the middle of the base plate 1. A pad can be placed in the receiving groove on the base plate as needed to adjust the height of the lead mesh mold.

[0018] The lead mesh is composed of multiple identical grid units arranged in sequence. The base plate 1 has clamping mechanisms on both sides of the receiving groove 100 for clamping two sections of lead mesh to be connected, ensuring that the last 1-3 grid units overlap on the lead mesh mold within the receiving groove. During casting and welding, the overlapping portion at the joint of the two sections of lead mesh to be connected is ensured to have excess lead liquid, guaranteeing that all grid units on the lead mesh are intact after connection.

[0019] Each clamping mechanism consists of an upper pressure plate 15 and a vertical clamp 12 for pressing / lifting the upper pressure plate 15 to clamp / release the lead mesh. The base 121 of the vertical clamp 12 is mounted on the base plate, and the front end 122 of the pressure rod is connected to the upper pressure plate 15. The base plate, the upper pressure plate, and the lead mesh mold are all made of stainless steel.

[0020] The cavity shape of the lead mesh mold 8 is the same as that of the two complete grid units. This utility model also includes a heating plate 2 that works with the lead mesh mold 8 to melt and form the end grid units of the two lead mesh sections into two complete grid units so that the two lead mesh sections are connected as a whole; a lifting mechanism for driving the heating plate 2 to rise / fall; and a double-button foot switch 5 for controlling the lifting mechanism to drive the heating plate to rise or fall.

[0021] The heating plate 2 is connected to the lifting mechanism via the fixed base 3. The lifting mechanism includes a hydraulic cylinder. The fixed base 3 includes a fixed plate 301 for fixing the heating plate 2 and a connecting rod 302 for fixing the fixed plate 301 to the outer end of the piston rod of the hydraulic cylinder. When the heating plate 2 descends, it is limited by the cooperation between the limiting surface 7 of the lower surface of the fixed base 3 and the limiting part 6 at the outer edge of the receiving groove on the upper surface of the base plate.

[0022] The lead mesh mold 8 is provided with a lead molten metal overflow port 13, and the base plate 1 is provided with a lead molten metal discharge hole 101 that communicates with the lead molten metal overflow port 13. A lead molten metal collection box 14, used to collect the lead molten metal discharged through the lead molten metal discharge hole 101, is movably connected to the lower part of the base plate. The base plate is provided with a mounting groove 102 for installing the lead molten metal collection box, and the lead molten metal collection box 14 is movably inserted into the mounting groove 102.

[0023] The lead mesh mold 8 is also equipped with a cooling water inlet 9 and a cooling water outlet 10.

[0024] In use, the ends of the two lead meshes to be connected are stacked on the lead mesh mold as needed. The two lead meshes are clamped and fixed to the base plate by two clamping mechanisms. The heating plate presses down to melt the grid units at the ends of the two lead meshes and form them into two complete grid units so that the two sections of lead mesh are connected as a whole. Excess lead liquid flows out through the lead liquid overflow port set on the lead mesh mold and enters the lead liquid collection box.
