Description

Technical Field

[0001] The utility model relates to the technical field of rounding machines, in particular to a metal sheet rounding machine. Background Art

[0002] Sheet metal processing is a comprehensive cold processing technology for metal sheets (usually less than 6mm), including shearing, punching, bending, welding, riveting, mold forming and surface treatment. Its most notable feature is that the thickness of the same part is consistent.

[0003] The conventional method of making arcs of small metal sheets is to use a bending machine to press and form them multiple times. Expand the size of the arc, calculate the positioning size of each bend, and calculate the angle of each bend based on the relationship between the total arc angle and the total number of bends.

[0004] This processing and manufacturing method is not only labor-intensive, but also requires the operator to have relevant technical and operational skills.

[0005] The patent with publication number CN203292303U discloses a steel plate disc pressing device, which specifically discloses "a steel plate disc pressing device, comprising an upper die (4) and a lower die (5), characterized in that: the steel plate disc pressing device also includes an upper bottom plate (1) arranged above the upper die (4) and fixedly connected to the upper die (4), a lower bottom plate (3) arranged below the lower die (5) and fixedly connected to the lower die (5), and a lower bottom plate (4) arranged above the lower bottom plate (3) and fixedly connected to the lower die (5). The bottom plate (3) is vertically connected to a guide column (2); the upper bottom plate (1); the guide column (2) is provided with a return spring (202) sleeved thereon" and the technical solution realizes the technical effect that "the utility model forms a shear force by mechanically moving the outer blade of the upper punch die and the inner blade of the lower die, and can press out a disc sample on a metal sheet of a certain thickness that meets the requirements of secondary processing embrittlement, forming lugs and drawing tests. The upper and lower dies are softly connected by a return spring, and can be unloaded, separated and reset after the disc is pressed."

[0006] However, the equipment uses die-cutting technology, which produces a lot of noise during processing, which will not only affect the physical and mental health of the processing personnel, but also affect other processes in the workshop. Noise reduction is urgently needed to protect the physical and mental health of the workshop personnel. Utility Model Content
