[0024] The T-profile production line of the present invention is equipped with a panel stereoscopic warehouse. After the web is processed at the cutting center and before it is transported, the scanning gun identifies the web. The panel warehouse receives the information of the web, automatically grabs the corresponding panel and puts it into the roller web plate or panel plate. After the incoming material is encoded, it is automatically stored in the above-mentioned stereoscopic warehouse. Each panel plate and each web plate has an independent code. When the T-profile needs to be assembled, the control system in the production line can transport the corresponding panel plate and web plate for further processing according to the code. The whole process does not require human intervention and runs automatically.

[0025] refer to Figure 1 The steel plate cutting system shown comprises:

[0026] A web plate input buffer roller 1 is provided with a pallet, and the web plate input buffer roller 1 is provided close to a stereoscopic warehouse for storing web plate materials; the web plate input buffer roller 1 takes out corresponding web plate materials from the stereoscopic warehouse storing web plate materials according to production requirements through a small workstation crane, and places the web plate materials on the pallet to be transported to a subsequent unit of the T-profile production line;

[0027] The panel transverse input roller 2 is provided with the pallet, and the panel transverse input roller 2 is provided close to the stereoscopic warehouse for storing panel plates; the pallet on the panel transverse input roller 2 is used to place the panel plates taken out from the stereoscopic warehouse for storing panel plates according to production needs, so as to be transported to the panel chamfering station;

[0028] The panel chamfering station 3 is connected behind the web plate input buffer roller 1 and the panel transverse input roller 2, and is provided with a grinding wheel, a grinding belt, a milling cutter or other special tools. The panel chamfering station 3 is used to remove slag and burrs on the edges and corners of the panel plate and / or web plate;

[0029] A paint removal and polishing unit 4 is arranged along the T-profile production line after the panel chamfering station 3, and is used to remove paint and floating rust on the surface of each plate corresponding to the welding position to ensure welding quality;

[0030] A panel web input unit 5 is arranged along the T-profile production line after the paint removal and polishing unit 4, and is used to position the panel plate and the web plate according to the parameters required for production;

[0031] A T-profile assembly unit 6 is arranged along the T-profile production line after the panel web input unit 5, wherein a hydraulic system is provided for pressing and fixing the web plate and the panel plate for welding;

[0032] The welding unit 7 is used to set the welding leg parameters corresponding to the welding position according to the production requirements, and use the welding equipment to perform positioning welding on the T-profile fixed by the T-profile assembly unit 6;

[0033] The turning and loading unit 8 is provided with a turning station crane, which is used to turn over and straighten the T-profile after the welding unit 7 completes the positioning welding of the T-profile, and then use the turning station crane to transport the straightened T-profile to the pallet.

[0034] In one implementation mode, the above structure, after the web material required for welding the T-profile is processed in the cutting center, the information is scanned. On the one hand, the scanned web is transported to the matching station; on the other hand, the information is transmitted to the panel warehouse, and the panel warehouse automatically calls the corresponding panel according to the web information to enter the sub-conveyor roller 2. The panel chamfering, paint removal at the panel welding position, paint removal at the web welding position, panel web storage, loading, automatic input of panel web, T-profile assembly, welding, straightening during welding, and automatic turning over and loading. Therefore, the present invention can perform feeding control according to production needs, automatically sandblast the ends and center lines of the plates before the cutting process, and perform double-line automatic welding after the plate assembly is completed, so as to realize the integration of welding correction.

[0035] The web plate input buffer roller 1: The web plate that has been unloaded and loaded in the pallet is transferred to this station through a small station crane. The web plate input buffer roller 1 can buffer 4 to 6 T-profile web plates and is equipped with a handheld scanner. Before performing the above transfer of the web plate, the barcode part name on the web is scanned with a handheld scanner. The information system sends the scanned part name information to the workshop control system, and the workshop control system can assign the corresponding T-profile panel plate to be transported out of the three-dimensional warehouse.

[0036] The panel transverse input roller conveyor 2 transports the T-profile panel sheets delivered from the stereoscopic warehouse to the panel chamfering station 3. The roller conveyor of the panel transverse input roller conveyor 2 can buffer 4-6 panels, and the speed meets the overall production efficiency of the assembly line, and the overall transportation speed can be adjusted by the assembly line master control center.

[0037] The web plate input buffer roller 1 and the panel transverse input roller 2 mentioned above can also be equipped with multiple sets of positioning mechanisms thereon to automatically position the panel and the web plate twice.

[0038] The panel chamfering station in the above system: use grinding wheels, sanding belts or milling cutters to remove slag and burrs from the edges and corners of the plate; use special tools to extrude or mill the edges and corners of the plate to form an arc with a radius of R2 to ensure paint adhesion and have noise reduction and dust removal functions. The sandblasting process in this station is automatic and continuous. This station can also be further equipped with an abrasive closed circulation system to reduce the amount of material handling and reduce the pollution of production dust to the working environment.

[0039] The welding unit 7 in the above system can adopt double-wire welding technology: it confirms the part name of the T-profile to be welded by calling the workshop master control system, uses this part name to search the model database, confirms the welding leg parameters of the web panel welding position of this T-profile, and uses double-wire MAG to automatically complete the full welding with a high-speed welding machine. Since the double wires are welded on both sides of the web at the same time, the heating and cooling of the web and panel are carried out simultaneously, so the two sides are not easily deformed due to temperature difference. At the same time, double-wire welding can also integrate a web correction device to correct the deviation when the web is still in a hot state, thereby effectively saving the floor space required for the correction device originally set at the rear end.
