The invention relates to the technical field of battery sealing nail welding, and provides a battery sealing nail welding defect repairing method. The repairing method comprises the following steps: acquiring an aluminum wafer of which the diameter is greater than that of a liquid injection hole of the battery top cover; removing the sealing nail at the liquid injection hole of the top cover of the battery; cleaning a liquid injection hole area; carrying out penetration type stitch welding by taking the wafer as an upper layer and the battery top cover as a lower layer to form a welding seam for melting the wafer and the battery top cover into a whole; and treating the welding seam and the wafer, enabling the outer surface of the wafer to be flush with the outer surface of the battery top cover, and enabling the liquid injection hole area not to be visually recognized. According to the repairing method, the aluminum wafer and the battery top cover are subjected to penetration stitch welding, and the welding seam and the surface of the wafer are treated, so that the welding defect of the sealing nail is repaired, the situation that the battery is degraded and scrapped due to poor welding or appearance defect of the sealing nail is avoided, and the quality requirement of the battery is met.

The utility model discloses a kind of tank wrapping machine for oil tank production, including multiple groups of fixed placement on the ground material supporting platform, upper pressing assembly and flap assembly;By using the present device, the manufacturing speed of oil tank can be accelerated, the flap assembly set, mechanical folding of oil tank plate is realized, greatly reduces manpower;By setting the press roll, the plate can be further leveled in the flap process, to avoid uneven stress on the plate during folding, resulting in uneven situation during folding;The upper pressing assembly set can conveniently press the plate after folding, to avoid plate springback, affect the welding effect in tank;By setting the sprocket assembly, it is convenient to transport oil tank plate to fixed position, and it is also convenient to transport welded oil tank out of material supporting platform;When using the present device to manufacture oil tank, it is manufactured using a whole steel plate, there is only one weld, and the safety of the oil tank is high.

This invention discloses a manufacturing and forming method for steel wire mesh reinforced tubes, relating to the technical field of steel wire mesh reinforced tubes. The method includes the following steps: S1, fixing the steel wire unwinding coil onto the cross-shaped positioning rod using a cross-shaped positioning rod, and using the magnetic force of a stopping electromagnetic ring to attract and fix the position of the metal limiting block and the cross-shaped positioning rod. The steel wire is then passed through the steel wire docking box, tensioning guide wheel, burr removal channel, and steel wire welding wheel located at the top of the welding support shaft seat. This invention has a scientifically sound and reasonable structure, and is safe and convenient to use. Through the cooperation of a detection camera, electrically controlled wire clamping pliers, a sleeve electric push rod, and hydraulic crimping pliers, the detection camera observes the steel wire passing through the steel wire docking box, thereby clamping and fixing the end of the old steel wire, limiting it below the hydraulic crimping pliers to prevent the steel wire from running out. Simultaneously, it facilitates moving the hydraulic crimping pliers and sleeve to the top of the end of the old steel wire.
