Problems solved by technology

[0002] Most of the existing industrial doors are in the shape of "Γ" or "1". There are multiple wooden boards assembled through hinges. The sliding rail on the side slides to realize the opening and closing of the industrial door. In practical applications, due to the heavy weight of a single wooden board, it is not only easy to separate the two connected wooden boards through a simple hinge, but the connection is not firm. When the hinge connects the two boards together, the operator is easy to be caught by the hinge

Embodiment 1

[0034] The first hinge sheet 1 includes a ceramic filling part and a metal layer arranged on the outer layer of the ceramic filling part. The ceramic filling part is mainly made of silicon carbide ceramics and at least part of the outer layer of the main body is a silicon nitride ceramic surface layer (that is, on the surface of the main body A certain area or some areas or the entire surface has a silicon nitride ceramic surface layer), the composition and weight percentage of the metal layer are: C: 0.20%, Si: 0.28%, Cr: 1.25%, Ni: 0.12% , Mo: 0.5%, Mn: 0.6%, Ti: 0.09%, B: 0.22%, and the balance is iron.

[0035] Among them, the ceramic filling part includes one (it can also be any of the following: the ceramic horizontal rods are provided with two, three, four, five or more parallel regular or irregular) columns (columns include cylinders) , elliptical prism, prism and other irregular prisms, prisms include triangular prisms, quadrangular prisms, pentagonal prisms, etc.) ce...

Embodiment 2

[0037] The difference between this embodiment and Embodiment 1 is that the composition and weight percentage of the metal layer in this embodiment are: C: 0.17%, Si: 0.35%, Cr: 1.2%, Ni: 0.2%, Mo: 0.3 %, Mn: 0.8%, Ti: 0.06%, B: 0.3%, and the balance is iron.

[0038] And the ceramic filling part also includes ceramic vertical rods, the ceramic vertical rods are perpendicular to the inside of the first hinge piece 1 and the minimum distance between the ceramic vertical rods and the surface layer of the metal layer is 1.0-1.5 mm.

Embodiment 3

[0040] The difference between this embodiment and Embodiment 3 is that the composition and weight percentage of the metal layer in this embodiment are: C: 0.25%, Si: 0.22%, Cr: 1.3%, Ni: 0.05%, Mo: 0.8 %, Mn: 0.3%, Ti: 0.12%, B: 0.05%, and the balance is iron.

[0041] And the ceramic filling part further includes ceramic oblique rods, and the ceramic oblique rods are obliquely arranged with the ceramic horizontal rods and the ceramic vertical rods.

Abstract

The invention provides an anti-pinch hinge for an industrial door, belongs to the mechanical technology field, and solves the problem of poor quality of the existing hinge for an industrial door. The anti-pinch hinge for the industrial door comprises an adjustment sheet, as well as a first hinge sheet and a second hinge sheet which are in hinge connection through a rotary shaft, wherein a winding drum is formed at the side of a first horizontal part of the first hinge sheet; a rotary shaft is arranged in the winding drum in a penetrating manner; strip-shaped holes are formed in a vertical part; location bolts are fixed in the strip-shaped holes in a penetrating manner; the first hinge part comprises a ceramic filling part and a metal layer arranged on the outer layer of the ceramic filling part; the ceramic filling part is formed by taking silicon carbide ceramic as a main body and at least partially arranging a silicon nitride ceramic surface layer on the outer layer of the main body; and the metal layer comprises the following composition ingredients in percentage by weight: 0.17-0.25% of C, 0.22-0.35% of Si, 1.2-1.3% of Cr, 0.05-0.2% of Ni, 0.3-0.8% of Mo, 0.3-0.8% of Mn, 0.06-0.12% of Ti, 0.05-0.3% of B and the balance iron. The anti-pinch hinge for the industrial door, which is provided by the invention, has the advantages of being simple in structure and high in safety.

Description

technical field [0001] The invention belongs to the technical field of machinery, in particular to an anti-pinch hinge for industrial doors. Background technique [0002] Most of the existing industrial doors are in the shape of "Γ" or "1". There are multiple wooden boards assembled through hinges. The sliding rail on the side slides to realize the opening and closing of the industrial door, but in practical applications, due to the heavy weight of a single wooden board, it is easy to separate the two connected wooden boards through a simple hinge, and the connection is not firm. When the hinge connects the two planks together, the operator is easily caught by the hinge. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the prior art, and propose a hand-pinch-proof hinge for industrial doors with simple structure and good safety. [0004] The purpose of the present invention can be achieved through the foll...
