Problems solved by technology
[0002] The processing technology of the existing car seat frame is cumbersome and the production efficiency is low
In addition, the positioning accuracy of the headrest installation guide sleeve and the guide sleeve support plate of the headrest installation support is poor, and the fitting gap is large. The headrest installation guide sleeve is prone to excessive thermal deformation during the welding process, resulting in excessive size of the guide sleeve or Too small and other issues
The bent wire frame is a semi-finished product that has been welded. The steel wire on it is deformed due to welding heat. When the splicing assembly is installed, there is often a problem that the value of the lap gap between the bent wire frame on both sides and the metal plate stamping part in the middle is uncertain. During the welding process lead to poor solder joints or even missing solder joints; moreover, the position of each solder joint in the existing processing technology needs to be checked manually by the operator, and there is no special equipment to monitor the quality
At the same time, the metal plate stamping part located in the middle of the seat frame splicing assembly, as the main connection point of the seat frame frame, is the benchmark for the installation position of the entire seat frame; the welding position of the metal plate stamping part in the existing processing technology is easy to appear Deflection, which in turn leads to deflection of the entire seat frame, which seriously affects the assembly of the car seat
In addition, the seat frame processed by the existing production process has poor compressive and tensile properties, the frame is easily damaged under the action of strong impact force, and the use safety is poor

Embodiment Construction
[0034] according to Figure 1-12 The specific steps of the present invention are described in detail. The production process of the automobile seat steel frame includes the following steps: Step 1, selection of steel wire material. The steel wire raw materials for making the steel frame of the seat are high-quality steel wires with diameters of φ4, φ5 and φ6 and high-grade tensile properties (the tensile strength can be as high as 2160MPa). According to specific process requirements, the composition content of the steel wire material can be C: 0.040%, Mn: 0.320%, Si: 0.080%, P: 0.009%, S: 0.004%.
[0035] Step 2. Processing of various wire bending parts. On the B3 and BM30 wire bending machines of Wafos, the steel wire is bent according to the bending shape of the wire bending parts to be produced; to produce various semi-finished wire bending products required for welding the steel frame of the seat. After the first wire bending part is produced, use Aicon's P8 inspection ...

Abstract
The invention relates to a production technology process of an automobile seat steel-iron skeleton. The production technology process of the automobile seat steel-iron skeleton solves the problems that an existing automobile seat skeleton processing technology is tedious in process and low in production efficiency, and a seat skeleton product is poor in compression resistance and tensile strength, easy to damage, and poor in use safety. The production technology process comprises the steps of selecting steel wire materials, machining various bent wire parts and metal plate stamping parts, welding a bent wire skeleton semi-finished product, integrally welding a seat skeleton, carrying out electrophoresis processing on the surface of the seat skeleton, carrying out ultrasonic welding, and the like. According to the production technology, a technology process of a traditional seat is simplified, and the production efficiency is improved; and in addition, the processed seat steel-iron skeleton has favorable compression resistance and tensile strength and high skeleton strength, can bear higher impact force, is not prone to damage, and is durable in use and beneficial to effectively improving the use safety of the seat.
Description
technical field [0001] The invention belongs to the technical field of seat processing, and specifically relates to the production of a car seat steel frame that can make the seat withstand strong impact force, has high frame strength, is not easy to be damaged, is durable, and can effectively improve the safety of the seat. process flow. Background technique [0002] The processing technology of the existing automobile seat frame is cumbersome and the production efficiency is low. In addition, the positioning accuracy of the headrest installation guide sleeve and the guide sleeve support plate of the headrest installation support is poor, and the fitting gap is large. The headrest installation guide sleeve is prone to excessive thermal deformation during the welding process, resulting in excessive size of the guide sleeve or Too small and so on. The bent wire frame is a semi-finished product that has been welded. The steel wire on it is deformed due to welding heat. When ...
