A corner curler

Abstract

The invention discloses a corner edge crimping tool, and relates to the field of heat preservation water tanks. The crimping tool comprises a base, wherein a first adjusting plate is fixed on the base, the first adjusting plate is of a strip-shaped structure, a first opening is formed in the upper end of the first adjusting plate, and first arc contact surfaces are arranged at the two ends of thefirst opening; and a second adjusting plate which is arranged perpendicular to the first adjusting plate is further arranged on the first adjusting plate, the second adjusting plate is of a strip-shaped structure, a second opening is formed in the upper end of the second adjusting plate, and second arc contact surfaces are arranged at the two ends of the second opening. According to the corner edge crimping tool, crimped edges are subjected to multiform adjustment such as stretching, extruding, deformation and angle change through any two or three arc contact faces, the second adjusting plateis detachably installed on the first adjusting plate, so that a plurality of fine adjustment modes are realized, the reliability of fine adjustment is guaranteed, when the arc contact surfaces is in contact with corner edges to be crimped, the damage to the corner edges is lower, a rubber sleeve is arranged to help an operator operate the whole device better, and the operation is more convenient.

Description

technical field [0001] The invention relates to the field of thermal insulation water tanks, in particular to a corner crimping device. Background technique [0002] The thermal insulation water tank is different from the stainless steel fire water tank. The thermal insulation water tank refers to the addition of special industrial and thermal insulation materials in the interlayer of the water tank, so that the water tank must maintain a certain temperature to meet the needs of life or industry. Insulation water tanks can be divided into stainless steel insulation water tanks, pressure insulation water tanks, and glass fiber reinforced plastic insulation water tanks according to the different materials used for processing. [0003] Thermal insulation water tanks can be simply divided into cylindrical and cubic shapes according to their shapes. The production process of cylindrical thermal insulation water tanks is generally to roll out the sides first and then cut the botto...

Problems solved by technology

[0003] Thermal insulation water tanks can be simply divided into cylindrical and cubic shapes according to their shapes. The production process of cylindrical thermal insulation water tanks is generally to roll out the sides first and then cut the bottom cover and top cover, while the existing bottom cover and top cover need to be reserved Place a part of the copper parts for flanging to form crimping, and then weld the crimping and side edges of the bottom cover firmly. During the flanging process, there may be some positions that are concave or convex compared with the actual required shape. In this case, when the side is welded, either the side cannot be stuck into the side or extra space is left. The welding process is more complicated. Generally speaking, it will inevitably result in a waste of man-hours, reduce production efficiency and may affect the quality of the thermal insulation water tank. Therefore, it is necessary to perform local fine-tuning on the crimping to ensure the best position during welding. The current crimping fine-tuning devices are too complicated, which is neither convenient to operate nor economically efficient.
