Description
Technical field
The utility model relates to heavy truck automobile technical fields, more specifically to dress clod wash Q on a kind of heavy truck automobile
Shape subframe longitudinal beam.
Background technique
In the prior art, Q shape subframe longitudinal beam is filled on heavy truck automobile and generally use clod wash Z-type and L-type fashioned iron group welding method, lead to
It crosses and Z, L-type fashioned iron is placed on group weldering platform, be fixed with special fixture, protected by welding of common welder or carbon dioxide gas
Shield weldering, manually welds twice its group being welded into Q type subframe.
However, subframe longitudinal beam is mainly welded by the L shape and Z-shaped group of clod wash or bending, production efficiency is low.With host
Factory is shorter and shorter to the manufacturing cycle requirement of conversion enterprise, delivers conversion enterprise order on time and brings huge challenge.In addition,
Since existing conversion enterprise is using artificial group weldering, it will appear deformation after group welding, need to largely be done over again, container quality
It is difficult to reach the requirement of user.Original subframe assembly welding technique causes weld seam that can only be single-sided welding, and lower section naturally forms
Stress is concentrated, and when truck is under the influence of overloading or by different operating conditions, group weldering subframe is easy to appear tearing and disconnects, influence
Traffic safety.Container is caused to be the shearing force received to the weld seam above subframe by structure type, the same loading capacity the case where
Lower automotive light weight technology loss of weight space is smaller.
In conclusion how to efficiently solve subframe longitudinal beam is caused container to the weld seam above subframe by structure type
It is the shearing force received, the problems such as automotive light weight technology loss of weight space is smaller in the case where same loading capacity, is current this field skill
Art personnel's problem to be solved.

The structure of specific stringer blank please refers on above-mentioned heavy truck automobile in each embodiment of dress clod wash Q shape subframe longitudinal beam
Related statement, details are not described herein again.In the step, hot rolling lath, which is specifically as follows, obtains hot-rolled sheet coil longitudinal shearing slitting,
It is exactly before step 1 further include: by hot-rolled sheet coil longitudinal shearing slitting, obtain hot rolling lath.
Continuous roll bending slightly forms, specifically can be by the way that 12 passage flat roll frames, 3 passage standing roller frames are arranged, and passes through imitative
True software carries out sunykatuib analysis optimization, reduces deformation angle to the biggish place of moulding stress, to the lesser increasing of moulding stress
Big deformation angle, to reduce the concentration of stress.Specific deformation angle size is set as needed, and does not make herein specific
It limits.The technique setting of specific continuous roll bending formation also not limitation and above-mentioned setting, can refer to company conventional in the prior art
Continuous roll bending formation technique requirement, is not especially limited herein.
S2: the top of the second vertical section 4 of thick stringer blank after molding is welded with first horizontal segment 1.
S3: the stringer blank after welding is cut to preset length after reducing mill stand shaping.
Specific reducing mill stand shaping process can refer to shaping process processing conventional in the prior art, not limit specifically herein
It is fixed.The size setting of size length according to needed for user of specific preset length.
Hot rolling lath is slightly molded stringer blank by clod wash unit continuous rolling is curved by the process, and since its is whole
Body have plate be integrally formed it is in rectangular configuration, and the interface of rectangle be located at the second vertical section 4 top and first horizontal segment 1 it
Between, since top surface and the first horizontal segment 1 of the second vertical section 4 offset, and by the top of the second vertical section 4 and first horizontal segment 1
Welding, thus subframe longitudinal beam by platform floor stringer active force be extruding force, compared to the prior art in subframe longitudinal beam
For shearing force by platform floor stringer, force structure changes, and since weld seam is become by shearing force by pressure, improves
The safety of product.And under same loading capacity and operating condition, the wall thickness of subframe longitudinal beam can be relatively thin, to mitigate vehicle
Self weight, realize energy-saving and emission-reduction.And pass through continuous roll bending formation, it is then welded, then by being cut to use after reducing mill stand shaping
Length needed for family produced in lengths can be suitable for different vehicles acording to the requirement of user, overcome former bending, punching press length
Limitation.Material yield strength range is in 235MPa~700MPa.
Further, it is welded as high-frequency resistance welding.The characteristics of cutting off afterwards can be first formed based on continuous roll bending formation, is used
High-frequency resistance welds, compared to the prior art the middle truck Q shape subframe longitudinal beam made of manually group is welded after bending,
The artificial group weldering workload for reducing automobile repacking enterprise, greatly improves working efficiency, reduces cost of labor.And it is connect by high frequency
Touching welding, speed of welding and weldquality are greatly improved, simultaneously.
Further, step S2 specifically:
The two sides on 4 top of the second vertical section of stringer blank are welded with first horizontal segment 1 respectively.Inside and outside namely
It is welded respectively with first horizontal segment 1, the defect of inside can not be welded by compensating for artificial group weldering, reduced stress concentration, improved
Travel safety under different vehicle conditions.
On the basis of the various embodiments described above, the head end of first horizontal segment 1 upwardly extends to be formed for vertical with platform floor
The positioning section 5 that beam cooperates to position.By the setting of positioning section 5, it can cooperate with platform floor stringer and position, and then be convenient for vapour
The installation of vehicle conversion enterprise, while in the running positioning of vehicle, guiding makes compartment raising during compartment is in raising decline
Decline more steady.The structure of specific positioning section 5 may include in vertical third vertical section 51 and by third vertical section 51
Top is folded upward at the segmental arc 52 to be formed to the side far from the second vertical section 4.Namely segmental arc 52 is as shown in Figure 1
, extended outwardly by the top of third vertical section 51, that is, the left side in figure extends, and formation arc protruding upward.According to
It needs, the concrete shape of positioning section 5 is not limited to shape, can also be according to the shape phase with platform floor stringer cooperation position
