Description
Technical field
The present invention relates to a kind of special-shaped structural part installed for bus seat, more specifically refer to a kind of car
Clod wash seat fixed Materials And Manufacturing Processes.
Background technology
All the time, the profile structure used in the fixing seat of traditional car is substantially Medium And Low Strength Steels square tube+flute profile
Section bar carries out manual welding and formed, and this installation for being primarily due to traditional car relies primarily on artificial operation, to working hour and
Car body weight is simultaneously insensitive.And such Medium And Low Strength Steels square tube+grooved profile is low due to production technology threshold, convenient and valency is purchased
Lattice are cheap, are conducive to the control of cost.
In recent years, with the continuous implementation of national energy-saving emission reduction policy, vehicle lightweight regulation is more harsh, and traditional is low
Intensity steel profile has no longer been adapted to lightweight requirements and the cost control requirement of car, and this just promotes using high-strength steel even
Super-high strength steel as its product raw material, to reach high-strength thinned effect.
In addition, with the development of national economy, the labour cost of China also rises year by year, traditional labor-intensive production
Just substituted by the advanced integrated production of automation.And the competition that integrated with full speed with international counterparts industry positive in recent years of domestic car, it is
Reach and mitigate car body weight, reduction labour cost, the purpose for improving product quality and stability, bus body is to can be by structural member
The cry more and more higher of integral precision special-shaped material is integrated as with functor.
The content of the invention
There is provided a kind of fixation section bar of car clod wash seat and its manufacture work in order to solve above-mentioned problem by the present invention
Skill.
The present invention is adopted the following technical scheme that：
A kind of clod wash seat of car fixes section bar, including a profiled body, and any longitudinal section of the profiled body is " 6 " word
Shape, the profiled body includes a rectangular square tube played a supportive role and a wing plate for fixing car clod wash seat, the square
Shape square tube and wing plate are integrally formed by a strip, wherein, the rectangular square tube upper end-face edge has an arc adapter section, the wing
Plate is bent to form from the arc adapter section to extending sideways.
Further, the upper surface of the wing plate is concordant with the upper surface of the rectangular square tube.
Further, the longitudinal section of the wing plate is laterally disposed L-type structure.
Further, the wing plate is the double-deck L-type structure being bent to form back and forth by the strip.
Clod wash seat of the present invention fixes the manufacturing process of section bar, comprises the following steps：
（1）, strip selection：The thickness of section bar and the length selection thickness and width phase of cross section expansion are fixed according to clod wash seat
The strip of adaptation；
（2）, the accurate leveling of the roller of strip 21：By the accurate leveling process of online 21 roller, leveling is carried out to strip；
（3）, clod wash seat fix section bar rough rolling step：Upper and lower paired deformation roll is mainly used in rough rolling step, and in portion
It is aided with edger roll and oblique cutting roller in shunting time, is that the clod wash seat that roughing shapes fixes the section bar stage by belt steel rolling；Rough rolling step
Be the 1st passage to the 25th passage, wherein in the 1st passage into the 21st passage, complete clod wash seat fix section bar agent structure into
Shape, in the 22nd passage into the 25th passage, shrinks roll seam, extrudes tab portions raw material；
（4）, the laser welding stage：By online CO2 laser welding process, coordinate two groups of squeeze rolls of the 26th passage, will be cold
Curved block chair fix section bar 3 blocks of raw materials of tab portions in combination with；
（5）, clod wash seat fix section bar finishing stage：During roll deformation, the 27th passage to the 30th passage is to roughing
Clod wash seat after shaping and laser welding fixes section bar and carries out finishing, reaches every required precision.
During rolling deformation, each stage arc section progressively shapes, two layers of raw material gap of wing plate from large to small, finally
It is equal with product value.
Above-mentioned fixed section bar roll the 1st passage into the 8th passage, the type heart is progressively moved up；In the 9th passage to the 30th road
In secondary, the type heart keeps constant.
Above-mentioned steps（5）In, the 27th passage to the 29th passage uses four-roller separate type straightening heads, to ensure the plane of product
Degree and linearity；30th passage uses turks-head roll straightener, and adjustment clod wash seat fixes the torsion resistance of section bar.
