Technical Field

The utility model relates to a foil strips production field especially relates to special knot formula of drawing of copper strips continuous type air cushion annealing stove production line and sews up mould.

Background

For the current domestic copper processing continuous air cushion annealing furnace production line, in the continuous production process, an upper tape head and a lower tape tail need to be sewn quickly, because the tape runs at high speed, the loop storage time is limited, the time left for sewing by an operator is only about 1-2 minutes according to the process, the tape runs at high speed immediately after sewing, the tape head needs to run at high speed through the whole line and goes through an alkali washing process section, a loop process section, a furnace area high-temperature process section, an acid washing process section and a winding process, the tape cannot be broken in the whole process section, otherwise, the whole furnace area production is influenced, the furnace shutdown causes huge waste of the whole plant operation cost, in addition, the tape cannot stay in the furnace area, otherwise, the tape is scrapped due to over-fire oxidation.

The thickness specification of the domestic continuous type air cushion furnace production line copper belt is in the range of 0.1-2.0mm, the common width is 450mm, 650mm specification, and the current sewing mode mainly includes:

1. welding type sewing: the welding machine mainly aims at the thin strip within the range of 0.1-1.0mm, and adopts an imported argon arc welding machine and a plurality of welding guns to punch holes for welding by overlapping a strip head and a strip tail. The disadvantages are as follows: the welding process is complex, the welding range can not cover the whole strip with the thickness of 0.1-2.0mm, the welding machine and the welding gun are easy to damage, the price is high, and the cost of accessories of the imported welding machine is high. The welded sewing head has a lot of welding slag and deformation, welding smoke emission is also considered at the position of a welding machine, the environment is dirty, air pollution is caused, the rubber roller at the process section is easily damaged by the belt head, and the belt material on the surface of the high precision is damaged due to the scratch of the roller.

2. The method for sewing the copper processing line through the steel wire is characterized in that the steel wire is firmly sewn, after the head, the tail and the head are overlapped, a hydraulic die is pressed by a single row of teeth, 1 sawtooth shape is formed in the middle, steel wires are threaded and buckled, and the head, the tail and the tail are connected.

3. Riveting and sewing, wherein riveted buttons are required to be plugged into riveting ports off line when in sewing aiming at thin strips with the thickness of 0.1-1.0mm, then the thin strips are pushed into a sewing machine to start hydraulic sewing of the head and the tail of the strip, and the sewn joints are very smooth and have no bulges.

The invention discloses a pulling and buckling type sewing die for a copper strip continuous air cushion annealing furnace production line, which is characterized in that a sewing head of an air cushion furnace needs to be detected in addition to comparison of different sewing methods, so that a later process can conveniently lift a roller to prevent scratches, a round hole needs to be punched in front of the sewing head, a later process detector can conveniently detect the position of the round hole, the position of the sewing head can be conveniently known by a system, and the roller lifting time can be conveniently calibrated, punching devices need to be independently arranged on a welding machine, a hydraulic sewing penetrating steel wire can simultaneously punch the round hole, riveting can be carried out, but on the basis of the original working procedures, steps are added, the operation complexity and the consumed time are increased, so that pulling and buckling type sewing die.
