Abstract

The invention discloses a stainless steel composite ground sill specially used for an elevator and a forming technique thereof, which includes a steel supporting plate arranged on ground beams of an elevator landing door and a car door, a first supporting plate end and a second supporting plate end are arranged at the top of the steel supporting plate, and a plate cavity extending to the inner bottom of the steel supporting plate is formed between the first supporting plate and the second supporting plate; stainless steel panels are adhered on the upper planes of the first supporting plate end and the second supporting plate end, The stainless steel panel has a U-shaped groove that can fit with a sliding block at the lower end of the elevator door and the groove is inserted into the plate cavity; the forming technique passes through a steel supporting plate forming procedure, a stainless steel panel forming procedure, a steel supporting plate fixed length cutting procedure, a stainless steel panel fixed length cutting procedure, an assembly procedure and a finished product procedure; the product can have reasonable structure. The stainless steel panel provided by the invention adopts roll forming technique of the stainless steel band, which is easy to manufacture and generalize and is low in cost; the structural design of wrapped edge has the advantages that the product is rustless, wear-resistant and beautiful in appearance.

Description

technical field [0001] The invention relates to the technical field of sill manufacturing in elevators, in particular to a special stainless steel composite sill for elevators and its forming process. Background technique [0002] At present, the competition in the elevator market is increasingly fierce, and the products are constantly updated; major elevator companies are intensively simplifying, replacing and improving on the premise of ensuring quality. The sills laid on the elevator car doors and landing doors are traditionally made of cast iron or aluminum alloy materials. The sills made of cast iron are easy to rust, heavy and unsightly, and are generally used on freight elevators; aluminum alloys are used Although the sills made of materials are beautiful and rust-free, they are easy to oxidize and wear, and the cost is relatively high, so they are generally used on passenger elevators. [0003] Be that the Chinese invention patent " door device of elevator " (notifi...
