Material plate used for manufacturing door plate

Abstract

The invention relates to a material plate used for manufacturing a door plate. A first plate body is formed by integral extrusion, and a hinging hole can be directly used as a door mounting hole. In the actual using process, the material plate can be formed adaptively only through further door frame adaption cutting or widening of the material plate, the manufacturing technique of the material plate is simple, and the complicated assembling processes in subsequent door plate manufacturing are avoided; the first plate body is provided with a first cavity, and a plurality of first supporting reinforcing bar parts are arranged parallelly at intervals to divide the first cavity into a plurality of first through holes formed in a mode of being spaced in the left-right direction; through the first through holes, the quantity of using materials of the door plate is decreased, and the weight and cost are reduced; the first supporting reinforcing bar parts are supported on the upper side and the lower side of the first cavity correspondingly, accordingly, an anti-impact structure of the material plate is reinforced, and the anti-impact performance of the front face of the door plate can beensured while the cavity is formed; and meanwhile, the material plate is formed integrally and provided with the multiple first through holes, and thus the door plate has good sound insulation and heat insulation performance.

Description

technical field [0001] The invention belongs to the technical field of door panel production, in particular to a material panel used for manufacturing door panels. Background technique [0002] Doors are the most common things in life. There are doors for rooms, doors for cars, and doors for trains. Doors for different purposes have different strength requirements. There are wooden doors and metal doors. But nowadays, with the development of science and technology and the progress of human beings, the doors used in automobiles, trains, subways, high-speed rails, home doors and other occasions are all made of metal materials; [0003] The strength requirements of the door during use are mainly to withstand the force from the front, and at the same time, in order to facilitate installation and transportation, it is necessary to control its weight as much as possible, especially for vehicles such as automobiles and high-speed rails that need to ensure speed.

[0003] The strength requirements of the door during use are mainly to withstand the force from the front, and at the same time, in order to facilitate installation and transportation, it is necessary to control its weight as much as possible, especially for vehicles such as automobiles and high-speed rails that need to ensure speed. There are safety requirements for the strength of the door, and there are also requirements for the weight of the door, but these two performances are in conflict with each other;
