Problems solved by technology

However, during welding, because the length of the elevator sill is relatively long, the worker cannot quickly and conveniently locate the guide 13 when holding the guide 13 for welding, and it is easy to cause the position of the guide 13 to shift during the welding process. , resulting in defective products
And it is also very troublesome when welding, which takes a long time and reduces production efficiency

Abstract

The invention relates to a bending process and bending equipment of an elevator sill. The bending process comprises the steps of cutting a plate to be machined, forming a bending groove in the plate to be machined, bending the plate to be machined to form a base piece and a guide piece and bending the plate to be machined through the bending equipment. An elevator sill body can be produced quicklyand precisely; a defective rate of the elevator sill is reduced; and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of elevator accessories, in particular to an elevator sill bending process and bending equipment thereof. 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. as attached figure 1 As shown, the elevator sills of today generally consist of a base member 12 and a guide member 13 . The base member 12 includes a first bottom plate 31 , opposite sides of the first bottom plate 31 are folded toward the same vertical side to form a second bottom plate 32 , and the two second bottom plates 32 are parallel to each other. The guide 13 includes a first guide plate 41 , a second guide plate 42 , a third guide plate 43 , a fourth guide plate 44 and a fifth guide plate 45 . The second guide plate 42 is provided with two pieces, and is arranged along two opposite sides of the first guide pl...
