These are all the connections of steel cable and blocky part, and whole weight is great, and be unsuitable for occasions that have strict requirements on weight such as aerospace.
In order to reduce the weight, people connect the steel cable and the sheet by welding, as shown in fig. 2, in order to use a cable ring tray structure on a sewing piece, wherein the tray is the sheet to be connected with the steel cable, the sheet is made of 304 stainless steel and has a thickness of 0.5mm, the steel cable is woven of stainless steel wires and has a diameter of about phi 1.5, and a part of the steel cable is embedded in an R0.75 arc groove on the sheet.
The welding method of the steel cable and the thin plate has the following problems: 1) The adopted tin brazing welding seam has low strength and poor appearance, and the steel cable is easy to pull off in the using process and pollutes the environment after being discarded; 2) The steel cable is easy to brittle fracture after surface treatment; 3) Soldering efficiency of manual soldering iron is low; 4) The wire rope is exposed to the outside and easily scratches the sewing member, so that the entire wire rope needs to be subjected to a deburring process.
Disclosure of Invention
The invention aims to provide a method for welding a steel cable and a thin plate, which has the advantages of less deburring amount, high steel cable pulling-out force, strong corrosion resistance and high processing efficiency.
The technical scheme adopted by the invention is as follows:
a method for welding steel cable to thin plate includes sticking steel cable to thin plate, covering a pressing plate on the steel cable, spot welding at several positions on said pressing plate and thin plate, pressing steel cable tightly by said pressing plate and thin plate, and spot welding at least two positions on said pressing plate, thin plate and steel cable.
Further, the thin plate is a plane or a curved surface.
Furthermore, the fixed position of the steel cable and the thin plate is more than one.
Further, the cable is threaded out of a fixed position press plate or sheet and threaded back to form a cable pull ring.
Further, the wire rope forms a wire rope loop between two adjacent anchor locations.
The invention has the beneficial effects that:
the pressing plate is additionally arranged to cover the other side of the steel cable, so that the exposed area of the steel cable is reduced, the deburring amount is less, and only the end of the steel cable needs to be polished for a single steel cable pull ring structure, so that the steel cable pull ring structure is suitable for occasions with sewing parts; resistance spot welding is used for replacing soldering iron welding, the welding seam strength is good, the pressing force is good, at least two positions are integrally fused, the soldering iron brazing pull-out force is 60kgf through a comparison test, the pull-out force of the steel cable is 120kgf-200kgf, the pull-out force of the steel cable is improved by more than one time, and the safety performance is improved; the heating and cooling time of the resistance spot welding is short, the corrosion resistance of the stainless steel part is ensured, and the corrosion resistance is proved through salt spray test; the method can be used for processing by using common AC/DC spot welding equipment, only a plurality of spot welding are needed, the processing time is short, the soldering iron is used for soldering one piece for 15-20 minutes, the resistance spot welding time is shortened to be within 1 minute, and the efficiency is high.
