Bending process and bending equipment of elevator sill

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...

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] refer to figure 2 with image 3 , which is a bending process for an elevator sill disclosed by the present invention, comprising the following steps:

[0038] Step 1: plate cutting, the raw material plate is cut by a cutting machine to form a rectangular plate to be processed 1;

[0039] Step 2: Opening folding grooves 2, a total of eleven folding grooves 2 are opened on the upper surface and the lower surface of the plate to be processed 1 by the milling cutter, and one side of the plate to be processed 1 is called a plate edge 11, Each folding groove 2 is parallel to the sheet material edge 11, and the folding groove 2 is a V-shaped groove, and the folding groove 2 is successively named as the first groove 21, the second groove 22, the The third groove 23, the fourth groove 24, the fifth groove 25, the sixth groove 26, the seventh groove 27, the ...
