Description

Technical Field

[0001] The utility model relates to the technical field of metal shearing equipment, in particular to a high-strength steel longitudinal shearing machine with adjustable spacing. Background Art

[0002] Slitting machine, also known as slitting machine, slitting machine, is suitable for longitudinal shearing of metal strips and rewinding the slit narrow strips into coils. Slitting machine generally includes a base, an upper cutter shaft mounted on the base, a lower cutter shaft, and a pair of upper and lower cutters set on the upper and lower cutter shafts. The upper and lower cutter shafts are mounted on the base through bearings, and one end of the upper and lower cutter shafts is driven to rotate by a power mechanism.

[0003] In this regard, the Chinese utility model patent with authorization announcement number CN219211798U discloses a slitting machine, which adds a bearing oil tank, a heat exchanger and an oil pump; a circulation path is formed by an oil inlet pipeline and an oil outlet pipeline, and the lubricating oil circulates in the bearing oil tank and the heat exchanger through the action of the oil pump. While the lubricating oil lubricates the bearing, the lubricating oil is cooled by the heat exchanger to remove a large amount of heat generated by the long-term rotation of the balls in the bearing, thereby preventing the balls from expanding due to overheating and causing the knife shaft to deviate, thereby causing the upper and lower cutters to deviate, resulting in the upper and lower cutters cutting positions not being in the same straight line, and ultimately causing uneven cutting of the metal strip or even inability to cut completely. The bearing lubrication is ensured while the temperature of the bearing during operation is reduced, thereby greatly improving the service life of the bearing, and having good economy and practicality.

[0004] The existing longitudinal shearing machine is equipped with a cutter, which is fixed and installed. The distance between the two sets of cutters is fixed and cannot be adjusted. It can only cut high-strength steel of the same specification. It has poor flexibility and low practicality. Therefore, we propose a high-strength steel longitudinal shearing machine with adjustable spacing to solve the above problems. Utility Model Content
