Problems solved by technology

The current seat windshields are all assembled from one-piece parts, each part uses more materials in production, and generates a lot of material waste, which increases production costs and causes waste of resources. It needs to be assembled, the overall strength of the seat windshield is not high, and the installation is troublesome

Embodiment Construction

[0029] The method for manufacturing seat windshield of the present invention, as Figures 1 to 8 As shown, it is mainly divided into two parts.

[0030] Part 1: First use a long profile to make the frame of the windshield.

[0031] First bend the middle part of a long profile, and the bend is an obtuse angle, so that the backrest part of the windshield can be tilted forward.

[0032] Then bend the top and bottom of the bend forward at the same time, and the new bend is a smooth transition, forming the back panel 1 located at the rear, the upper panel 2 located at the upper part and the lower panel 3 located at the lower part, and the upper panel 2 is at a right angle to the upper part of the back panel 1, and the lower panel 3 is at a right angle to the lower part of the back panel 1, so that the distance between the upper panel 2 and the lower panel 3 is moderate, preparing for the next step, and making the next step The mold of the process is more compact, saving the numbe...

Abstract

The invention discloses a method for manufacturing a seat wind screen. A long profile is used for manufacturing a frame of the wind screen. The method is simple, materials are saved, cost is low, production is fast, and the integrity of the frame is high. The two ends of the profile are fixedly connected with corresponding parts respectively, and therefore the overall strength of the frame is improved. Corner angles do not exist at the edge where the wind screen makes contact with a passenger, and therefore the passenger is prevented from being injured, and the overall attractiveness of the wind screen is improved. The upper portion of a rear board of a backrest leans forwards and a lower board of a seat stretches upwards so that the seat backrest installed on the wind screen can lean forwards and a seat board of the seat can stretch upwards. Because the included angle between the seat backrest and the seat board of the seat is an acute angle, the phenomenon that the body of the passenger slides downwards because of shaking generated in the running process of a train is avoided, the sitting comfort of the passenger is guaranteed, and sitting stability is guaranteed as well. Outlines of all bent portions and outlines of all overturned portions can be circular, and therefore mold production and manufacturing are facilitated, and mold production cost is reduced.

Description

technical field [0001] The invention relates to a method for manufacturing components, in particular, a method for manufacturing seat windshields. Background technique [0002] In the compartments of rail vehicles such as subways and light rails, in order to accommodate as many passengers as possible, the seats are generally benches installed on both sides of the compartment, and there are windshields on both sides of the seats to provide a comfortable environment for the seats. Passengers can block the wind blowing in from the outside of the car, and it can also be used as a hand rest and armrest. The current seat windshields are all assembled from one-piece parts, each part uses more materials in production, and generates a lot of material waste, which increases production costs and causes waste of resources. It also needs to be assembled, the overall strength of the seat windshield is not high, and the installation is troublesome. Contents of the invention [0003] Th...
