Description

Processing method for simultaneous feeding and cutting

Technical Field

The invention relates to the field of laser flat plate cutting, in particular to a processing method for simultaneous feeding cutting.

Background

In the existing laser coil stock cutting processing method, on one hand, feeding is required to be carried out according to the length of a figure file in a processing file before cutting, and cutting is started after feeding is completed, so that a period of waiting for feeding is provided, and the time consumption is often long. On the other hand, the method has a requirement on the length of the processing rail and the mechanism itself, i.e. the length of the generated processing rail must not be greater than the length of the feed that can be accommodated by the mechanism. In addition, because a certain length of edge (generally 5-10 mm) needs to be reserved at the edge of the coiled material during cutting, the length of the reserved edge at two sides of a cut part needs to be reserved during cutting, 10-20 mm of coiled material is wasted when each plate is processed, and the amount of the wasted coiled material is large during large-scale processing.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 schematically shows a part of the structure of a feed cutting processing method in the prior art. As shown in fig. 1, in the conventional laser coil stock cutting method, when cutting is performed on a coil stock 6 along a cutting line 7, it is necessary to provide margins 8 at both sides of the cut portion of the coil stock 6, and the length of the margins 8 is generally 5 to 10 mm. Therefore, 10-20 mm of the coil stock 6 is wasted every time the coil stock is processed, and the total amount of the wasted coil stock 6 is large in the large-scale processing.

Fig. 2 schematically shows the structure of a machining method of a co-feed cutting according to an embodiment of the present invention, and fig. 3 shows the flow of the machining method of a co-feed cutting in fig. 2. As shown in fig. 2-3, the method is used for laser cutting machining of a web 6. The method requires a work table 1, corresponding laser welding equipment and a control system, etc., wherein the laser machining equipment is mounted on the work table 1, so that the coil stock 6 can pass over the table top of the work table 1 and be subjected to laser cutting machining of the welding head of the machining equipment.

In the machining method of the simultaneous feeding and cutting, a plurality of regions are first divided on the table 1, and a waiting region 2, a machining region 3, and a blanking region 4 are respectively provided from one end of machining and feeding to the other end. Wherein specific parameters (such as length values and the like) of each area, in particular the waiting area 2 and the processing area 3, are provided with a figure file in the control system.

The associated system and equipment is then activated to begin the process, at which point the coil stock 6 is fed at a rate onto the table 1. Wherein, for the convenience of calculation and processing, the feeding speed should be kept at a constant speed.

When the coil stock 6 passes through the waiting area 2, the feeding speed is calculated. The feeding speed is calculated according to the drawing file of the waiting area 2 and the passing time, for example, the length of the waiting area 2 in the drawing file is D, and the time for the coil stock 6 to pass through the waiting area 2 at a certain position is T, so that the feeding speed is V ═ D/T.

When the web 6 passes through the processing zone 3, the welding head of the welding processing apparatus performs laser cutting processing on the web 6. Because the feeding process is always kept at a constant speed, the feeding speed of the processing area 3 is also V, and a welding head of the processing equipment can be matched with the speed to cut and process the coil stock 6 in real time.

In addition, in order to meet certain processing requirements (such as processing of a special large drawing file), the feeding speed can be changed in real time according to needs, and the changed speed can be calculated and used for processing through the method.

And finally, feeding the cut coil stock 6 into a blanking area 4 for blanking.

In addition, a recovery area 5 is provided on a side (set as an outer side) of the loading and unloading area 4 of the table 1 away from the processing area 3, the recovery area 5 is lower than the loading and unloading area 4, and a material receiving mechanism is installed in the recovery area 5. Wherein, receiving agencies comprises work or material rest and gyro wheel to carry out drive control through the motor. The coil stock 6 can be discharged into the recovery area 5 after passing through the discharging area 4, and is received by the receiving mechanism, so that the accumulation of excess stock is avoided.

Therefore, according to the processing method of the synchronous feeding cutting, a customer can not consider the actual length chart of the mechanism, can cut while feeding, and can adjust the feeding speed in real time in the set processing area 3 so as to meet the processing requirements of special large drawing files. In addition, a receiving mechanism is also arranged in the recovery area 5 to synchronously recover the excess materials.

In conclusion, the machine table can be always in processing without stopping for waiting for feeding in place, so that the processing time is saved, the processing efficiency is improved, and the rear coil material is recycled, so that the coil material does not need to be cut and the edge is reserved, and the material is saved.

What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
