Material, obtains crash bar front connector, crash bar rear joint and two spacer rings after stamped processing；
S4, it is fixedly connected sequentially a spacer ring and crash bar front connector in the leading inside of anticollision bar body by bolt,
It is fixedly connected sequentially a spacer ring and crash bar rear joint in the rear inside of anticollision bar body by bolt；
S5, by the outer ledge of junction, anticollision bar body between anticollision bar body and crash bar front connector and prevented using adhesive tape
The outer ledge of junction bonds together between lance rear joint, and anticollision bar body is obtained after drying.
Preferably, in abovementioned steps S2, extruding feed speed is 1.2 ~ 1.3mm/s, and controlling slower speed can be to avoid
The problem of inhomogeneities and drawing crack of flow of metal.
More preferably, in abovementioned steps S2, the extruding temperature of extruder is constant at 450 ~ 480 DEG C, avoids squeezing temperature mistake
Pull crack caused by height.
It is highly preferred that aluminum profile first carries out the pre-heat treatment before being put into extrusion cylinder in hot stove in abovementioned steps S2, preheat
Temperature is heated up to 350 ~ 400 DEG C, by slow the pre-heat treatment, by aluminum profile using the warm form of ladder of 50 DEG C/0.5h of heating
Temperature increases, and avoids the problem that it enters in the extrusion cylinder of high temperature suddenly and generates drawing crack, to improve product quality.
The invention has the beneficial effects that: car front/rear door Novel crashproof bar of the invention is using aluminum profile as crash bar
Ontology, the crash bar front connector at both ends and crash bar rear joint are all made of irony metal plate, can preferably connect with vehicle body, and aluminium
Connect with both ends iron material using special bolt nut connect, after stick adhesive tape, body member structure can be simplified, reduce vehicle weight
Amount, to reduce production cost and car amount of fuel, enhances the collision performance of body structural member, makes the security performance of passenger
It is enough to be further guaranteed；By controlling temperature in extrusion process and squeezing feed speed, the uneven of flow of metal can avoid
The problem of property and drawing crack；Aluminum profile first carries out the pre-heat treatment before being put into extrusion cylinder, can avoid its extruding for entering high temperature suddenly
