Embodiment Construction

[0017] Such as figure 1 As shown, the elevator door sill is a chute structure, which is composed of a base plate 3, a chute plate 2, a bracket block 1, a hook block 4 and the bending angles connecting them. The bending angles a, b , c, d, e, f are right angles. Such as figure 2 As shown, the elevator door sill has two chute structures, which are composed of a base plate 3, a left chute plate 2, a right chute plate 6, a connecting plate 5, a bracket block 1, a hook block 4 and a bending joint between them. Angle composition, the bending angles a, b, c, d, e, f, g, h, i, j are all right angles. The sill of the elevator door has clear edges and corners, each bending angle is a right angle, the elevator door is not easy to slip out of the chute of the sill, and the safety factor is high. In order to make the elevator door sill more practical and beautiful, surface decoration treatment can be carried out by galvanizing, plastic spraying, electrophoretic paint, spraying colored ...

Abstract

The invention relates to a lift door sill which is composed of a basal plate, a runner plate, a support block, a hook block and bent angles connected between the support block and the hook block. The bent angles are right angles. The manufacturing method of the lift door sill comprises the following steps: metal plate materials with 1.5-5mm thickness are cut into strip blocks according to needed sizes and peripheral burr is removed; the strip blocks are planned with V-shaped slots according to the designed positions and order, the field angle of the V-shaped slot is from 80 to 95 DEG, the depth of the slot is 0.5-0.8 times as much as the thickness of the plate materials; the plate materials which are opened with the V-shaped slots are arranged in a bending die, and are bent into right angles according to the design order; the bent-forming products are carried through superficial treatment. The bent angle of the lift door sill manufactured by utilizing the method is a right angle, and the safety coefficient is high. The manufacturing method has the advantages of less equipment, small occupied place, raw material conservation, low energy consumption, no secondary environmental pollution, low manufacturing cost and mass production, and can be used in various sightseeing lifts, passenger lifts, goods lifts, etc.

Description

technical field [0001] The invention relates to an elevator door sill and a processing method thereof. Background technique [0002] An invention patent application publication with a document number of CN101070131A discloses a rolled elevator door sill, the arc of each bending angle is relatively large, and the elevator door is easy to slide out of the elevator door during the opening and closing process. The chute of the ridge has a low safety factor. Another invention patent application publication with the document number CN101125623A discloses a composite elevator sill and its production method. The composite elevator sill is composed of a base and a sheath plate covering the base. The base is concrete or Reinforced concrete, the panels of the sheathing panels are stainless steel. The production steps of the composite elevator sill are as follows: First, roll the trough-shaped upper panel with stainless steel plate; then weld or connect and fix the end cover plate wit...
