Abstract
The invention belongs to machining technology field, more particularly to a kind of lightweight frame cross processing technology.The lightweight frame cross processing technology, it is characterized in that：Comprise the following steps：（1）, sheet material extruded into bathtub construction；（2）, positioning holding is carried out to the rear and front end and bottom of bathtub construction, and reserve crimping space on two aerofoil tops of left and right；（3）, the aerofoil top of bathtub construction or so two extruded, two aerofoil tops is curved inwardly；（4）, the part that curves inwardly to the aerofoil top of bathtub construction two push, it is bent to circular shape；（5）, bathtub construction bottom two ends are inwardly extruded, the flange that formation is flipped up.The beneficial effects of the invention are as follows：Without the processing such as welding, on the premise of ensuring that beam strength and rigidity and torsional strength are constant its weight is alleviated, realize the lightweight of product, it is to avoid crossbeam cracking phenomena, reduce vehicle own wt, reduce cost of transportation.
Description
（One）Technical field
The invention belongs to machining technology field, more particularly to a kind of lightweight frame cross processing technology.
（Two）Background technology
Heavy-duty automobile frame is the carrier for connecting other assemblies and parts as the matrix and main stressed member of vehicle, is made
The heavy burden load of various devices is not only born during, the various load outside from in-car are still suffered from, and because of road
The concavo-convex complicated shock loading for causing.Heavy-duty automobile frame in addition to including two longerons, also including front beam, intermediate transverse girder,
The various crossbeams such as balance shaft beam and transom beam, mainly consider bending strength and torsional strength during design, bending moment mainly by
Longeron is born, and torsional moment is mainly born by longeron with crossbeam.Work of the crossbeam of heavy-duty automobile frame in whole frame assembly
With being to increase torsional strength, while providing the assembly space and rigging position of remaining parts.In the prior art, heavy-duty automobile frame
Crossbeam in order to reach intensity, processed using heavy-gauge sheeting, preponderance, cost of transportation is high, and, crossbeam has in use
Cracking phenomena, exist profile it is not attractive in appearance enough the shortcomings of.In the case of sheet metal thickness is not increased, can produce same there is presently no one kind
Equicohesive lightweight crossbeam technique.
（Three）The content of the invention
The present invention is in order to make up the deficiencies in the prior art, there is provided a kind of process is simple, cost-effective, efficiency high, guarantee product
Intensity and rigid lightweight frame cross processing technology.
The present invention is achieved through the following technical solutions：
A kind of lightweight frame cross processing technology, it is characterized in that：Comprise the following steps：
（1）, sheet material extruded into bathtub construction；
（2）, positioning holding is carried out to the rear and front end and bottom of bathtub construction, and it is empty to reserve crimping on two aerofoil tops of left and right
Between；
（3）, the aerofoil top of bathtub construction or so two extruded, two aerofoil tops is curved inwardly；
（4）, the part that curves inwardly to the aerofoil top of bathtub construction two push, it is bent to circular shape；
（5）, release to the positioning of bathtub construction rear and front end, bathtub construction bottom two ends are inwardly extruded, form upward
The flange of turnover.
Preferably, in step（1）In, sheet metal thickness used is 4~6mm.
Preferably, in step（2）In, bathtub construction bottom is fixed on the positioning by location hole.
The beneficial effects of the invention are as follows：Without the processing such as welding, beam strength and rigidity and torsional strength are being ensured not
Its weight is alleviated on the premise of change, realize the lightweight of product, it is to avoid crossbeam cracking phenomena, reduce vehicle itself weight
Amount, reduces cost of transportation.
（Four）Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Accompanying drawing 1 is lightweight frame cross structural representation of the invention；
（Five）Specific embodiment
Accompanying drawing is a kind of specific embodiment of the invention.The embodiment is comprised the following steps：（1）, sheet material extruded into bathtub construction；
（2）, positioning holding is carried out to the rear and front end and bottom of bathtub construction, and reserve crimping space on two aerofoil tops of left and right；
（3）, the aerofoil top of bathtub construction or so two extruded, two aerofoil tops is curved inwardly；（4）, to bathtub construction both wings
Face top curves inwardly and is partly pushed, and it is bent to circular shape；（5）, release bathtub construction rear and front end is determined
Bathtub construction bottom two ends are inwardly extruded by position, the flange that formation is flipped up.In step（1）In, sheet metal thickness used
It is 4~6mm.In step（2）In, bathtub construction bottom is fixed on the positioning by location hole.
Using a kind of lightweight frame cross processing technology of the invention, thickness is as thin as 4~6 millimeters of sheet material pressure first
Go out bathtub construction, then drive alignment core to act with two sides cylinder action before and after composite die and go deep into workpiece slot, pass through
Location hole holds workpiece bottom and two aerofoils positioning tightly, and crimping space is reserved on two aerofoil tops.The oil cylinder of left and right sides two is moved
Make to drive the action of side mould slide block, make the two inside lateral bends in aerofoil top, then side oil cylinder drives side mould slide block to move back
Return.Upper cylinder action drives mould above descending, and crimping is molded simultaneously to make two aerofoils.Front and rear two sides cylinder action drives positioning
Flange is produced in core action, then detaches workpiece slot.Realize what is do not reduced in beam strength and rigidity and torsional strength
Under the conditions of weight saving, realize the lightweight of product, reduce vehicle own wt, reduce cost of transportation.
Claims (3)
1. a kind of lightweight frame cross processing technology, it is characterized in that：Comprise the following steps：
（1）, sheet material extruded into bathtub construction；
（2）, positioning holding is carried out to the rear and front end and bottom of bathtub construction, and it is empty to reserve crimping on two aerofoil tops of left and right
Between；
（3）, the aerofoil top of bathtub construction or so two extruded, two aerofoil tops is curved inwardly；
