The invention discloses a production process of lithium-ion battery tabs with high sealing and anti-leakage. In the production process, the base metal material is subjected to bright rolling and dull rolling through steps A-H, and then electrochemically polished and polished. passivation, cleaning and drying it, and then cut the strip-shaped metal conductor into sections, ultrasonic cleaning and drying it, and treating it with deionized water and drying it, and finally strip The polymer insulating film is pasted on the segmented metal conductor. The lithium-ion battery tab produced by this process increases the surface roughness of the metal conductor, which increases the effective contact area between the metal conductor and the polymer insulating film, so it can effectively improve the adhesion and make the two bonds more stable, thereby Improve the sealing performance of the battery cell and improve the welding performance of the metal conductor. At the same time, it reduces the surface activity of the metal conductor and enhances its ability to resist electrolyte erosion, thereby further improving the sealing performance of the battery cell and preventing lithium-ion batteries from leaking.

The invention discloses an auxiliary welding device for auto parts, which comprises a fixing seat, fixing plates are fixed on both sides of the top outer wall of the fixing seat, and two through holes are opened on one side of the outer wall of the fixing plate, and the two The inner walls of the two through holes are slidingly connected with guide rods, the outer walls of one side of the two guide rods are fixed with a connecting plate, and the outer wall of one side of the connecting plate is connected with a rotating shaft through a bearing, and one of the other fixed plates The side outer wall is rotatably connected with a rotating rod through a bearing, and a U-shaped frame is fixed on one side of the rotating rod and one side of the rotating shaft, and a hydraulic rod is fixed on the top outer wall of the fixing seat. The invention can prevent the auto parts from slipping from the inside of the splint due to the centrifugal force generated during rotation and affect the welding of the auto parts, can prevent the arc generated during welding from causing burns to the eyes of the operator, and can disperse the arc to avoid the damage caused by the arc. Damage to the operator's eyes.

The invention relates to the technical field of mechanical equipment, in particular to an automatic docking device for the production of automobile mufflers, which can effectively simplify the docking method by performing automatic docking processing on the muffler parts, save physical strength and time during manual operation, and simultaneously The accuracy of the docking position of the muffler parts is improved, the stability and firmness of the parts are improved, which facilitates subsequent welding work, effectively improves product production quality, and improves practicability and reliability; including workbench, four sets of outriggers, two sets of second One guide rail, two sets of slide plates and two sets of push plates. The left and right sides of the middle of the workbench are horizontally provided with through grooves that penetrate up and down. The tops of the four sets of legs are evenly installed on the outside of the bottom of the workbench. The guide rails are installed horizontally on the top front side and the rear side of the workbench respectively.

The invention relates to the technical field of electrical connectors, in particular to a differential connector and an installation structure of a bent contact. The differential connector comprises an outer conductor and a center conductor arranged in the outer conductor. The center conductor is the bent contact. The center conductor comprises a horizontal section conductor and a vertical sectionconductor. A horizontal mounting cavity corresponding to the horizontal section conductor and a vertical mounting cavity corresponding to the vertical section conductor are arranged in the outer conductor. The horizontal section conductor and the vertical section conductor are integrated. The side of the outer wall of the vertical mounting cavity away from the horizontal mounting cavity is provided with an escape port which is used for avoiding the horizontal section conductor and the vertical section conductor so that the center conductor is enabled to enter the outer conductor along the axial direction of the horizontal mounting cavity or the side of the outer wall of the horizontal mounting cavity away from the vertical mounting cavity is provided with an escape port which is used foravoiding the horizontal section conductor and the vertical section conductor so that the center conductor is enabled to enter the outer conductor along the axial direction of the vertical mounting cavity.

The invention relates to the technical field of tooling processing of petroleum accessories, in particular to a thin steel plate welding equipment for tooling processing of petroleum accessories, which includes a base, a fixing unit and a welding unit, the fixing unit is installed inside the base, and the welding unit is arranged on the base Right end; the present invention can solve the problems existing in the welding between thin steel plates: two thin steel plates are usually butted manually, so that the angle between the steel plates cannot be effectively controlled, so that the two thin steel plates lack precision when butt jointed, and it is easy to cause two Large gaps and dislocations appear at the joints of the two thin steel plates, thereby affecting the welding effect; the present invention can respectively limit and fix the two thin steel plates, so that the stability of the thin steel plates during welding can be improved, thereby avoiding welding defects; The invention can adjust the angle between two thin steel plates, thereby enhancing the welding effect and improving the applicability of the equipment.

The invention discloses a multifunctional steel structure welding device, which comprises a bottom plate, a corresponding plate is arranged on the top of the bottom plate, the corresponding plate includes a first frame plate and a second frame plate, and a welding head. The present invention rotates the spacer sleeve, and the screw effect of the spacer sleeve and the movable screw makes the two clamping frames close to each other. At this time, when the two clamping frames clamp the elastic member, the second frame plate pairs with the clamping frame. The reaction force of the limiting sleeve and the driving force of the clamping frame, the two clamping frames use the ring groove to tightly clamp the collar, avoid the rotation of the clamping device and the limiting device, and ensure the stability of the steel structure welding; reverse Turn the limit sleeve, the elastic rebound of the elastic part makes the two clamping frames separate, and the clamping device and the limiting device can be rotated to facilitate all-round welding of the welding joints of the two steel structures and ensure the welding of the steel structures Effect.

The invention relates to a boiler economizer forming device and method thereof, comprising a bottom plate, a bending unit, an auxiliary unit and a support unit, a bending unit is installed on the top of the bottom plate, an auxiliary unit is installed on the right end of the bending unit, and A supporting unit is arranged behind the curved unit. The present invention can solve the problem that existing equipment cannot protect the pipe diameter at the bend of the economizer pipe fittings when bending and forming the economizer pipe fittings, thus destroying the integrity of the pipe fitting structure and easily There is a phenomenon that the pipe fittings cannot be used, which leads to waste of materials and reduces the effect of the bending and forming of the economizer pipe fittings. Inconsistencies in the width of the space, and can not ensure that the bent economizer pipe fittings are in a horizontal position, which is not convenient for welding between economizer pipe fittings, and increases the difficulty of economizer assembly and other problems.
