Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment manufacturing, in particular to a crescent shear device with a punching device. Background Art

[0002] In the metallurgical industry, the crescent shear is mainly used to cut off the extra-wide part of the edge of the strip at the weld. The crescent-shaped shearing of the strip weld can prevent the weld from scratching the roller, and facilitate the downstream disc shear to feed, extend the service life of the disc shear blade, and improve product quality. The existing crescent shear equipment is mainly composed of a transmission base, left and right tool holder components, a waste conveying device, etc. The equipment occupies a large area, has a loose structure, and a single function. Due to the continuous production of the entire line, it is necessary to arrange additional punching equipment to punch holes in front of the welds of the two strips. From the perspective of functional characteristics, the purpose of the use of the crescent shear and the punching equipment is similar. Both devices process the weld joints of the strip in different ways. However, the two devices are arranged separately, resulting in the dispersion of equipment functions, wasting the site space of the entire line, and increasing the difficulty of later equipment installation, commissioning and maintenance.

[0003] In addition, most of the existing punching equipment is installed by anchor bolts, which has poor installation accuracy. It is necessary to repeatedly adjust the assembly gap between the punch and the die on the punching equipment, which is difficult to adjust and has poor matching clearance. Since the punching equipment has high requirements for the foundation and high equipment installation accuracy, if the punching equipment is not installed and debugged accurately, it will lead to poor punching effect, serious burr and flanging of the hole, and over time it will reduce the punching accuracy, causing it to lose its function and affect the normal operation of the entire line unit.
