Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a shearing device facilitating the butt joint of a strip. Background Art

[0002] The roll forming of a metal strip is a widely applied cold deformation processing technology. During the roll forming production process, the raw material is generally a coiled strip, and the strip is formed through rolling in a certain order. During continuous mass production, whenever a coil is used up and a new coil is replaced, the problem of splicing the new and old strips will be faced. Generally, the head and tail shapes of the strips are not very regular and matching. In order to facilitate butt welding, the tail of the old coil strip and the head of the new coil strip need to be cut into matching cross-sections. In actual production, when shearing the new and old strips, the existing problems are as follows: after the existing strip is sheared, burrs often appear at the shearing positions of the head of the new strip and the tail of the old strip, and manual grinding is required before butt welding can be carried out, which increases the workload and affects the butt welding accuracy and efficiency; the reason for the large number of burrs is that, on the one hand, the constraint of the strip near the shearing line is insufficient, resulting in local deformation of the strip when it is stressed during shearing, causing burrs to be generated; on the other hand, the matching accuracy of the tool is insufficient, which also generates burrs.
