1. can realize automatic feeding, accurate cutting and automatic discharging and realize continuous operation

Feeding a plate of the laser cutting equipment, feeding the plate to a cutting machine tool along the longitudinal direction of a feeding table by a feeder, clamping and feeding a steel plate forwards by a feeding cross beam and a floating clamp, and positioning the plate left and right by matching with a rear stop and a front stop; specifically, the swing part of the floating clamp drives the lower clamp body to move upwards and the upper clamp body to clamp the plate vertically, the plate enters the feeding table top through the cooperation of the feeding cross beam to feed the plate in the longitudinal direction of the feeding machine body, the rear stop and the front stop simultaneously move left and right in a centering way, the front end of the plate enters the feeding table top and is limited to the left and right position by the front stop, the rear end of the plate enters the feeding table top and is limited to the left and right position by the rear stop, the plate entering the feeding table top can be limited to a certain position along the longitudinal direction due to the longitudinal symmetrical arrangement of the front stop and the rear stop, so that the feeding is completed through the feeding ball screw driven by the feeding servo motor, the positioning accuracy is high, the feeding is not easy to deviate, and the automatic feeding is realized;

According to the laser cutting equipment, the front net material cutting stop and the rear net material cutting stop are arranged in the net material cutting area, so that the plate which is fed into the workbench main body by the feeding machine in a precise positioning manner can be limited in a determined position, and the position requirement of the plate in cutting can be met; in the concrete implementation, the clean material cutting servo motor drives the front clean material cutting ball screw and the rear clean material cutting ball screw to enable each pair of front clean material cutting stop and rear clean material cutting stop to move symmetrically left and right respectively, the width between each pair of front clean material cutting stop and rear clean material cutting stop is automatically controlled and regulated through a system, the front end of the plate is limited to the left and right positions by the front clean material cutting stop, the rear end of the plate is limited to the left and right positions by the rear clean material cutting stop, the plate is accurately positioned, deviation between the actual position and the theoretical correct position of the plate is reduced, the cutting precision of clean material cutting is further ensured, and the defect that a common laser cutting machine cannot cut clean material is overcome; moreover, after the cut flat plate is moved to the rotary workbench, the plate entering the clean material cutting area is accurately positioned, and the plate entering the rotary workbench is still accurately positioned due to the integral movement, so that deflection is not easy to occur; thereby realizing accurate cutting, reducing the rejection rate of workpieces and improving the production efficiency;

When the sheet material is fed into the clean material cutting area, the sheet material is still a flat sheet surface after being cut in the clean material cutting area; then the plate after the clean cutting is moved to a rotary workbench, the workpiece is cut, the rotary workbench rotates, the workpiece on the rotary workbench is conveyed to the next unit, the rotary workbench is restored to a standby state, the plate which is not cut in the clean cutting area is conveyed to the rotary workbench again, the plate is continuously cut into single pieces of workpiece, and the continuous operation of cutting is realized by cyclic reciprocation; in addition, at the rotary workbench, the plate is continuously cut to form single-piece workpieces with irregular shapes and sizes, the single-piece workpieces are not easy to convey, and the rotary workbench can integrally move forwards, so that the irregular single-piece workpieces are automatically conveyed forwards, automatic conveying of the cut workpieces is realized, and automatic blanking is realized;

2. realize automatic deviation correction in the feeding process

In the laser cutting equipment, as the floating clamp is lifted to be an eccentric link mechanism and driven by the swinging component, the clamp can float left and right; compared with the common clamping mechanism, the left-right floating type plate clamping mechanism cannot float, if the plate is deflected when the feeder clamps the plate, the cutting precision is directly affected, and the two sides of the steel plate, the front part stop and the rear part stop can generate additional stress, so that the edges of the steel plate are subjected to plastic deformation such as bending and wrinkling, and the rejection rate of equipment is greatly increased; the floating clamp arranged on the feeding machine can greatly reduce the rejection rate, can feed at a higher speed, starts to float left and right when the sheet material moves forwards and backwards to be fed obliquely in the feeding process, drives the eccentric wheel to rotate along the intermediate shaft by the swinging component, realizes left and right floating through the spring plunger, the guide rail and the sliding block, automatically eliminates the lateral acting force of the front stop and/or the rear stop on the sheet material, avoids the curling of the sheet material in the feeding process, realizes automatic deviation correction in the feeding process, and improves the production efficiency.

3. The rotary workbench simultaneously realizes the functions of supporting and conveying workpieces

According to the laser cutting equipment, the rotary workbench and the clean material cutting area are arranged on the main lathe bed at the same time, and the rotary workbench is positioned at the front part of the clean material cutting area and is arranged along the longitudinal direction with the clean material cutting area; when the net material cutting area is used for cutting, the rotary workbench is static and supports the workpiece in the net material cutting area for cutting; after the material cleaning cutting area finishes material cleaning cutting, the plate moves to the rotary workbench to finish workpiece cutting, the rotary workbench rotates, and the workpiece on the rotary workbench is conveyed to the next unit; thus, the rotary workbench integrates the functions of supporting and conveying workpieces.
