Description:
A SHEET METAL CUTTING MACHINE

TECHNICAL FIELD

The invention relates to a sheet metal cutting machine for applying a cutting process on a sheet metal.

BACKGROUND

Cutting machines are devices that enable the desired pattern or design to be applied to the material by using a cutting structure such as laser beam, scraping a certain thickness of layer on the materials or cutting the materials in specific proportions. Cutting machines have been in use for many years in hundreds of sectors. Cutting machines can be processed with materials of different hardness and quality according to the configuration found on laser cutting machines, metal cutting machines, machines. It is possible to process almost all kinds of materials from steel to glass, from plastic to textile with a cutting machine. Cutting of flat plates can be easily done by performing two-dimensional scanning on cutting machines.

Incorrect cuts may occur depending on the structure of the plate during the cutting of plates that do not have a three-dimensional and uniform structure. Sheet metal plates with ducted structure are wrongly subjected to the cutting process due to the indentation formed between the channels. This situation causes the sheet metal to become unusable. In particular, the battery cooling plate consists of thin plates comprising one or more channels through which a coolant is pumped. Errors in the cutting process to be applied to plates such as battery cooling plates may cause the said plates to become unusable afterwards. This situation causes material losses.

In the present art, the image information of the holes opened by separate operations before the machine can be loaded on the part by the camera provided in the cutting machine is processed and the cutting process is carried out in two-dimensional plane according to the coordinate information received. Pre-drilling both creates an extra cost and causes loss of precision. All the problems mentioned above have made it necessary to make an innovation in the relevant technical field as a result.

The said cutting process is performed by laser cutting method in a possible embodiment of the invention. In an alternative embodiment of the invention, the cutting process is done by the plasma cutting method. In an alternative embodiment of the invention, the cutting process is done by the milling cutting method.

As shown in Figure 1 , the sheet metal cutting machine (10) comprises a cutting unit (100). There is a sheet loading unit (200) that allows the sheet metal (20) to be transmitted to the cutting unit (100). There is at least one cutting head that enables the cutting process to be applied to sheet metal (20) in the sheet metal cutting unit (100). The cutting unit (100) has at least one profile sensor (300) placed to see the sheet loading unit (200). It is preferred to use at least one profile sensor as the profile sensor (300) mentioned in a possible embodiment of the invention. As is known in the art, profile sensors enable objects to be detected in three dimensions.
