Problems solved by technology

Although the sill of this structure overcomes the shortcomings of the aluminum alloy material, after a period of use, the sill body and the bracket parts are easy to loosen and produce noise, or more seriously, the sill is twisted and uneven, resulting in Door opening and closing blocked
In addition, in this patent, the closed structure formed by the sill body and the bracket parts makes disassembly and maintenance inconvenient

Embodiment 1

[0023] This embodiment provides a figure 1 The manufacturing method of the elevator sill shown, it comprises the following steps:

[0024] (1) Using stainless steel strip material, the elevator door chute 10 is formed by rolling in the middle, which is the sill body 1;

[0025] (2) By cold bending and rolling, one side of the sill body 1 is bent longitudinally downward to form the first side arm 2, and the lower end of the first side arm 2 is further bent inward and extended horizontally to form the first side arm 2. The bottom bracket 4, the first bottom bracket 4 extends to the bottom middle position 9 of the elevator door chute 10, and makes its top surface touch the bottom surface of the elevator door chute 10; on the other side of the sill body 1, The second side arm 3 bent longitudinally downward is formed by cold bending and rolling, and the lower end of the second side arm 3 is further bent inward and extended to form a second bottom bracket whose lower end sur...

Embodiment 2

[0029] This embodiment provides a figure 2 The manufacturing method of the elevator sill shown is basically the same as that in Embodiment 1, the difference is that in step (2), the other side of the sill body 1 is first folded back downwards to form the upper part 30 of the second side arm 3, Then, the inner end of the upper portion 30 is bent downwards and extends vertically downwards to form the lower portion 31 of the second side arm 3 . In this example, the upper portion 30 is horizontal, but the upper portion 30 may also be inclined. In this way, on the one hand, hard contact with the real object can be avoided; on the other hand, the bearing strength of the sill body is better enhanced.

Embodiment 3

[0031] This embodiment provides a image 3 The manufacturing method of the elevator sill shown, it comprises the following steps:

[0032] (1) Using stainless steel strip material, the elevator door chute 10 is formed by rolling in the middle, which is the sill body 1;

[0033] (2) By cold bending and rolling, one side of the sill body 1 is bent longitudinally downward to form the first side arm 2, and the lower end of the first side arm 2 is further bent inward and extended horizontally beyond the elevator door The side wall of the chute 10 forms the first bottom bracket 4, and the top surface of the first bottom bracket 4 will be in contact with the whole bottom surface of the elevator door chute 10, and the welding machine installed on the cold-formed steel machine is also used to synchronously The position where the first bottom bracket 4 contacts the elevator door chute 10 is welded. On the other side of the sill body 1, the sill body 1 is bent longitudinally down...

Abstract

The invention relates to a manufacturing method for an elevator sill. The manufacturing method comprises the following steps of: (1) forming an elevator door chute via rolling in the middle of a stainless steel strap material to serve as a sill body; and (2) longitudinally bending two sides of the sill body downwards to form a first side arm and a second side arm via cold bending rolling, and respectively bending the lower ends of the first side arm and the second side arm inwards and extending the lower ends to form a first bottom bracket and a second bottom bracket, wherein the lower end faces of the first bottom bracket and the second bottom bracket are in the same surface, and the top surface of at least one of the bottom brackets is pushed against the bottom surface of the door chute. According to the method, the sill body and the part served as a bracket are arranged integrally, thus the obtained sill not only has high intensity, but also has attractive, simple and generous appearance and practicability. Additionally, by using the method provided by the invention, the shape of the second side arm can be designed conveniently to meet the requirements of different occasions inpractical application, and the types of the elevator sills are enriched.

Description

technical field [0001] The invention relates to a method for manufacturing an elevator sill. Background technique [0002] The elevator sill is installed between the vertical elevator doors, and plays a guiding role in the operation of the elevator car doors and landing doors. At present, for the convenience of processing and anti-rust and anti-corrosion, the traditional elevator sill is generally made of aluminum alloy extrusion molding, which has high manufacturing cost, is not wear-resistant, and the groove is easy to deform, which seriously hinders the opening and closing of the door. Collision or extrusion is prone to obvious scratches and bumps, and regular maintenance is required. Chinese utility model patent ZL 200820079885.9 discloses an elevator sill, which includes a sill body and a bracket part, and the sill body is connected to the bracket part through a connecting piece. Although the sill of this structure overcomes the shortcomings of the aluminum alloy mate...
