Processing method of automatic-feeding laser cutting

Abstract

The invention relates to the technical field of laser processing, in particular to a processing method of automatic-feeding laser cutting, which comprises the following steps of 1 uncoiling a coiled material into a flat plate through an uncoiler, and leveling the coiled material uncoiled into the flat plate through a leveler; and 2 pushing the coiled material leveled in the step 1 into a laser cutting work area through an automatic feeder, and cutting and processing the coiled material into a plurality of workpieces through laser. Therefore, the processing method of the automatic-feeding laser cutting has the advantages of 1 being free of noise, vibration and greasy dirt, safe and environment-friendly; 2 being capable of randomly being cut in a suit mode, and completely cutting the material in the suit mode theoretically to achieve zero waste material; 3 saving device materials and reducing problems of investment waste and environment pollution caused by casting of large-sized devices and corresponding moulds; 4 greatly improving production efficiency and rate of finished products of relevant industries; 5 being capable of obtaining high accuracy and good quality and being wide in application range; and 6 reducing operation and maintenance costs of the devices, energy consumption and invested operation cost of large-sized coil feed lines.

Description

technical field [0001] The invention relates to the technical field of laser processing. A processing method of automatic feeding laser cutting is specially designed. Background technique [0002] The current traditional steel coil uncoiling and shearing method: in the demand for steel plates in various industries, it is necessary to flatten the steel plate coil and cut it into various shapes by scissors cross-cutting, pendulum shearing, rolling shearing or mold blanking. Sheet metal for subsequent various sheet metal processing. [0003] The traditional steel coil uncoiling processing methods and processes have the following common shortcomings: [0004] 1) Environmental pollution: The traditional processing knife-edge and sheet metal contact shearing has large vibration and noise, especially when the punching machine is working, the vibration is very large, which is easy to affect the surrounding processing equipment and production. Punching machines are prone to oil...

AI Technical Summary

Problems solved by technology

[0004] 1) Environmental pollution: The traditional processing knife edge and sheet metal contact shearing, the vibration is large and the noise is large, especially when the punching machine is working, the vibration is very large, which is easy to affect the surrounding processing equipment and production

Punches are prone to oil pollution; 2) Performance disadvantages: due to the influence of mechanical up and down strokes, the shearing speed is relatively slow

[0006] 1) Cross-cutting processing method: only rectangular plates can be processed, but cannot be nested to save material, vibration noise, frequent tool maintenance, low speed, poor precision, not suitable for high-strength steel; 2) Rolling cutting processing method: low production efficiency, no It is suitable for complex and special-shaped sheet materials, which cannot be nested to save material, and is not suitable for high-strength steel, and the cost of hobs is high; 3) Mechanical punch processing method: large noise, large vibration, easy oil pollution, high energy consumption, and mold investment is required to realize nesting. It is necessary to increase mold investment, large investment, high installation and maintenance costs, not suitable for frequent production changes, and high safety risks; 4) Pendulum cutting processing method: only rectangular, trapezoidal, and parallelogram sheets can be processed, and cannot be nested to save material, vibration noise , tool maintenance is frequent, the speed is low, and the precision is poor, which is not suitable for high-strength steel; 5) Vibration shearing processing method: only rectangular, trapezoidal, and parallelogram sheets can be processed, and it cannot be nested to save material, relying on punching machines, with high noise and large vibration , high energy consumption, large investment, high installation and maintenance costs, and high safety risks;

[0007] Current laser cutting processing methods: At present, all laser cutting processing methods are semi-automatic production modes in which the coils are first uncoiled into regular sheets, and then the sheets are placed on the work table and laser cutting is used for secondary processing. The material consumption is relatively high. Large, high logistics costs, the biggest disadvantage is that it is impossible to carry out automatic flow production, which limits the application and promotion of laser processing technology
