Double-blade shear device of steel rolling line strip steel abutted seam laser welding machine

Abstract

The invention discloses a double-blade shear device of a steel rolling line strip steel abutted seam laser welding machine. The double-blade shear device is characterized in that an upper tool post isfixedly connected to an upper tool apron; a pair of upper blades is arranged at the lower end of the upper tool post; a lower tool post is fixedly connected to a lower tool apron; a pair of lower blades is arranged at the upper end of the lower tool post; the upper tool post is attached to the upper tool apron through an upper tool post vertical limiting mechanism; upper tool post left and rightadjusting mechanisms are arranged on the two sides of the upper tool post; and a lower shear blade gap adjusting mechanism is designed between the lower blades and the lower tool post. According to the double-blade shear device, the vertical limiting mechanism facilitates automatic alignment of the lower tool post by the upper tool post before shearing, so that lateral impact force on the lower tool post is reduced; the upper tool post left and right adjusting mechanisms limit the displacement distance of the upper tool post, so that the upper tool post does not exceed the automatic guide range to cause direct collision of guide plates; the shear blade gap adjusting mechanism gets rid of a conventional gasket mode to adjust a gap, and adjusts the shear blade gap independently at all points, so that the precision of the shear blade gap in the length direction is higher and more uniform; and the adjusting mechanism is convenient, rapid and practical in adjustment.

Description

technical field [0001] The invention relates to the technical field of double-edged shears, in particular to a double-edged shears device for a steel rolling line strip seam laser welding machine. Background technique [0002] With the rapid development of my country's automobile, bridge, construction, home appliance and other industries that have a large demand for steel, steel companies have higher and higher requirements for the output and quality of high-standard, cost-effective steel. At present, during the use of heavy-duty laser welding machines in the production lines of iron and steel enterprises, the quality of the double-edged shears and the quality of the strips are very strict. The stability of the double-edged shears and the upper and lower The cutting edge clearance of the blade directly affects the quality of cutting and stitching. [0003] The main function of the double-edged shear device is to cut the tail of one roll of strip steel and the head of the ne...

AI Technical Summary

Problems solved by technology

[0004] In the actual assembly process, the gap between the double-edged scissors is realized by padding, which is very cumbersome and inefficient, and the effect is not obvious

After the double-edged shearing device has been running online for a period of time, the guide plate will be damaged by friction and the cutting edge of the blade will be worn, which will also cause the gap between the upper and lower blades to be unstable, resulting in poor cutting quality, thereby affecting the seam and welding quality
