A welding-free assembly process for seamless fire doors

Abstract

The invention discloses a welding-free assembling technology of a seamless fireproof door and relates to the technical field of welding-free connection between all components of the fireproof door. The welding-free assembling technology of the seamless fireproof door comprises the following specific steps that S1, the seamless fireproof door comprises a door frame, wherein a plate is located and fixed to a high-density high-precision 45-degree angle cutting die machine tool, a cutter on the angle cutting die machine tool is controlled to conduct locating and cutting on the plate, the plate ismade into the door frame in an integrated formation manner through machine tool cutting, and the top and the bottom of the left side of the inner ring of the door frame are fixedly provided with plug-in components; the bottoms of the inner walls of the left side and the right side of the inner ring of a threshold are symmetrically provided with wedge grooves through drilling and milling equipment.The welding-free assembling technology of the seamless fireproof door is based on the wood mortise-tenon connection technology, a seamless seal-assembly method is adopted, a special cut opening design is adopted in combination with a hidden corner riveting method, and the welding-free assembling technology of the seamless fireproof door saves energy, is low in production cost and easy to operateand has the advantages of riveting.

Description

technical field [0001] The invention relates to the technical field of welding-free connection between components of a fireproof door, in particular to a welding-free assembling process of a seamless fireproof door. Background technique [0002] It is used for the connection between fire door steel, and it is generally completed by welding or riveting. Welding technology is a method commonly used to connect metals. At present, the main welding methods include ordinary electric welding and gas shielded welding. The gas shielded welding operation requires a complete set of equipment such as welding consumables, special welding machines, and gas cylinders; ordinary electric welding equipment is relatively simple, and it is more convenient for flexible and maneuverable operations. It is only necessary to bring the welding machine, welding consumables and power supply when working. The high temperature of welding will damage the surface treatment of the plate, and will also caus...

AI Technical Summary

Problems solved by technology

The high temperature of welding will damage the surface treatment of the plate, and will also cause local heat deformation of the plate

Although riveting solves the shortage of welding, it also brings screws and rivets. Too many riveting points will bring huge restrictions to the appearance treatment. If there are too few riveting points, the firmness will not be guaranteed.

[0003] The splicing of fire doors on the market mainly adopts the method of gas shielded welding, which not only requires a large investment in equipment, but also takes time and effort to complete the secondary surface treatment of the splicing joints, and the effect is not guaranteed.

There are relatively few riveting, and holes are punched on the corresponding plates, and the assembly remains unchanged, and the appearance is easily not accepted by the market.
