Problems solved by technology

[0002] With the continuous increase of urbanization and the rapid development of urban traffic, a large number of subway traffic projects have greatly promoted the development of the escalator industry. The forming of the elevator handrail bracket is mainly formed by iron mold roll bending, and there are many surface scars. It cannot be processed continuously, and the thickness of the product is easy to change during the processing, resulting in thinning of the thickness and affecting the strength and safety

Abstract

The invention discloses a heightened lug-free armrest support and further discloses a bending forming method. The heightened lug-free armrest support comprises a first side wall and a second side wall; a third side wall and a fourth side wall are arranged between the first side wall and the second side wall and connected through a flat and straight plate; the first side wall and the third side wall are connected through a first inclined side wall; and the second side wall and the fourth side wall are connected through a second inclined side wall. A cold-rolling mill conducts rolling forming onthe lug-free armrest support through a roller, an X5Cr18Ni9 plate is bent, and thus a large number of technological processes are reduced; and after rolling, the out-of-tolerance phenomenon or the torsion phenomenon of a sectional material does not occur, the thickness of the plate is unchanged, and the rough edge phenomenon is avoided.

Description

technical field [0001] The invention belongs to the technical field of elevator processing, and in particular relates to a heightened earless handrail bracket and a bending forming method thereof. Background technique [0002] With the continuous increase of urbanization and the rapid development of urban traffic, a large number of subway traffic projects have greatly promoted the development of the escalator industry. The forming of the elevator handrail bracket is mainly formed by iron mold roll bending, and there are many surface scars. It cannot be processed continuously, and the thickness of the product is easy to change during the processing, resulting in thinning of the thickness and affecting the strength and safety. Contents of the invention [0003] In order to solve the above problems, the present invention provides an elevated armrest bracket without ears and discloses a cold-rolled bending forming method. [0004] In order to achieve the above object, the pre...
