Method and system for two-station fast table cutting

Abstract

Provided are a double-station quick-table cutting method and a system adopting the method. The system comprises two cutting units, two carrying-stacking robots, four material feeding positions, four sheet material discharging positions and a waste material conveying system. Each cutting unit comprises a first mobile quick table, a second mobile quick table and two laser cutting heads, and the first mobile quick table and the second mobile quick table are parallelly arranged. Each mobile quick table is provided with one cutting position and two material receiving positions 1# and 2#. The carrying-stacking robots are respectively arranged on two sides of the cutting units, and external shafts of the robots are perpendicular to the mobile quick tables. The material feeding positions are arranged on the outer sides of the outside of the carrying-stacking robots and provided with material trolleys and corresponding guide rails, wherein the guide rails are parallel to the external shafts of the robots. The waste material conveying system is arranged under the cutting positions of the cutting units. The system can simultaneously achieve steel plate feeding and discharging operation, effectively improve the operation speed and the yield and can meet the small-scale production requirement.

Description

technical field [0001] The invention relates to laser processing technology in the field of automobile manufacturing, in particular to a method and system for loading, unloading and cutting steel plates. Background technique [0002] The existing auto sheet blanking adopts the mold blanking method, and the steel factory or the automobile factory usually has an automatic production line for uncoiling, shearing and stacking. Its equipment mainly includes: conveying unit, press unit and stacking unit. Simple blank shapes (such as rectangle, trapezoid and arc) can be cut by pendulum cutting, and blanks with complex curves can be blanked by mold. The blanking line needs to configure different blanking molds according to the size and shape of the blanks of the vehicle model, and produce different blanks by changing the molds. The operation efficiency of the auto sheet blanking line is very high, at 4 million to 6 million pieces per year. Calculated on the basis of 3800 hours pe...

AI Technical Summary

Problems solved by technology

There are still many technical difficulties in this method, such as the difficulty in realizing the high-speed cutting operation of multiple cutting heads at the same time in terms of technology and equipment; The influence of deviation on the cutting shape and the difficulty of realizing the follow-up of the laser head under high-speed cutting operations, etc.

In addition, in the method proposed by the patent, the huge configuration of multiple sets of laser cutters and cutting units and the floor space of the production line form a high investment in equipment
