Bending device for seat framework

Abstract

The invention particularly relates to a bending device for a seat framework. The bending device comprises a supporting unit, a curving unit and a bending unit, wherein the supporting unit is used forsupporting a steel wire to be bent and fixing the steel wire; the bending unit and the curving unit are arranged above the supporting unit; the bending unit is used for bending the steel wire on the upper surface of the supporting unit according to a certain angle; and the curving unit is used for curving the steel wire on the upper surface of the supporting unit according to a certain curvature radius. By arrangement of the supporting unit, the steel wire can be conveniently supported and fixed; meanwhile, by arrangement of the curving unit and the bending unit, the curving unit can curve thesteel wire, and the bending unit is used for bending the steel wire into a specified angle, so that various bending requirements of the steel wire are met; and the device can automatically bend the steel wire and is very convenient to use.

Description

technical field [0001] The invention relates to the technical field of cushion processing, in particular to a bending device for a seat frame. Background technique [0002] With the vigorous development of the national economy, the automobile has become an extremely important means of transportation today. The countries with developed industries abroad regard the automobile industry as one of the pillar industries of the allergic economy. The car seat is one of the indispensable accessories in the automobile. The so-called The car seat is the seat that is used when riding in a car. The comfort of the seat is very important in the personalized design of the vehicle, and it is also a part of ensuring the safety performance of the vehicle. A well-designed car seat can provide drivers and passengers with safety, Comfortable, easy to operate and less fatigue driving experience, the rapid development of automobile technology and the improvement of people's requirements for all asp...

Problems solved by technology

[0003] The car seat frame refers to the internal support frame of the car seat, which is usually welded by steel materials. The seat frame must be able to withstand a certain load, and the overall comfort of the seat is also closely related to the structure of the seat frame. , the buttock support structure of the existing seat frame is usually composed of multiple S-shaped springs distributed in an array, which only plays a simple supporting effect, and its structural firmness, stability and comfort are relatively general, and because The pressure of the buttocks on the seat is not uniform, and it is easy to cause the deformation of the spring after a long time of use. The deformation of the spring in the middle part is particularly serious, which affects the overall aesthetics and comfort of the seat. There are fewer contact positions on the head of the person, and the effect is not too great

[0004] In view of this, the existing problems are studied and improved. In addition to the main frame, the steel wire is generally processed into a variety of small frames of different specifications, such as figure 1 As shown, the combination of the small frame and the main frame can provide convenient, reliable, and comfortable support for the occupants. There is currently no suitable equipment for processing the small frame formed by bending or bending steel wires, and due to its There are so many types that it is difficult to complete processing with existing automation equipment
