Forming method of independent integral stainless steel seat

Abstract

The invention discloses a forming method of an independent integral stainless steel seat. The forming method comprises the steps that A, stainless steel plates with the thickness being 1.5 mm are adopted by seat face cover plates, forming die integral one-time forming stretching is adopted, injection molding is carried out so as to promote the surface structure of the steel plates to fully flow in the state that the plate thickness is not decreased, and therefore metal stress is generated, and the rigidity of the seat face cover plates is increased; B, a sectional material extruded and formed through an aluminum alloy is adopted in a reinforcement frame, stainless steel is embedded in the two ends of the reinforcement frame, a transverse connecting beam on the back of the reinforcement frame is formed by stretching a 2mm aluminum alloy plate, so that the rigidity of the reinforcement frame is increased, the reinforcement frame and the transverse connecting beam are welded, the reinforcement frame is matched with switches on the backs of the face cover plates, and the reinforcement frame and the face cover plates are welded; C, after a seat end plate is subjected to surface coating treatment, SMC material one-time compression moulding forming is adopted, and the seat end plate and a stainless steel insert are embedded when formed in the die; and D, glue is applied to the corresponding positions of the seat face cover plates and the seat end plate, the seat face cover plates and the seat end plate are compressed on a compressing mechanism frame, and meanwhile the stainless steel insert of the reinforcement frame and supports on the face cover plates are welded and formed. According to the forming method, the reinforcement frame and the face cover plates are matched accurately and closely, and the space needed for seat manufacturing production is saved.

Description

technical field [0001] The invention belongs to the technical field of interior decoration of rail transit vehicles, in particular to a seat used in a passenger compartment of a rail transit train and a forming method thereof. Background technique [0002] At present, the stainless steel seats used in traffic vehicles are all longitudinally arranged, so there is a problem that passengers cannot sit comfortably for a long time, and most of the seats are processed by ordinary mechanical connections. The binding force is not strong, it is easy to break down, and it also lacks the partial forming parts of the seat, which is unfavorable for installation and maintenance. In view of this, it is necessary to improve on this basis. Contents of the invention [0003] The invention provides a vehicle that satisfies the requirement that passengers face the forward direction of the vehicle, and the back of the seat is decorated with a stainless steel plate, so that the interi...
