Abstract
The invention discloses commercial vehicle front lower portion moulding process, comprising the following steps: selects the steel band of specified specification as main material, steel band is rolled into the profile with designated shape by flow forming process；Pass through the side welded closure of the profile after line welding technique is by rolling；Profile temperature after being welded first time by press quenching technology rises to 800 ~ 1000 DEG C；Profile after being heat-treated first time by cutting equipment is sawed into the profile of designated length.Step of the present invention is simple, and the intensity of front lower portion assembly after molding is higher, and compare traditional handicraft, and cost of labor is lower, high-efficient, highly-safe.In simple terms, after Overheating Treatment, the intensity of protection crossbeam can be effectively improved, effectively mitigation product weight.
Description
Technical field
The present invention relates to auto parts machinery manufacture fields, more particularly, to a kind of commercial vehicle front lower portion moulding process.
Background technique
Commercial vehicle front lower portion mainly includes protecting crossbeam, in traditional handicraft, in order to improve the intensity of automobile protective crossbeam, is adopted
The intensity of automobile protective crossbeam is improved with the thickness for increasing protection crossbeam, and the thickness for increasing protection crossbeam will certainly make vehicle
Weight penalty, therefore how do not increase protection beam thickness even reduced thickness under the premise of come improve protection crossbeam it is strong
Degree, is those skilled in the art's urgent problem to be solved.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of commercial vehicle front lower portion moulding process, be intended to by the technique come
It produces with high-intensitive, light-weight commercial vehicle front lower portion assembly.
The technical scheme of the invention to solve the technical problem is: commercial vehicle front lower portion moulding process, including with
Lower step:
(1) it rolls
It selects the steel band of specified specification as main material, steel band is rolled by the type with designated shape by flow forming process
Material；
(2) it welds for the first time
Pass through the side welded closure of the profile after line welding technique is by rolling；
(3) it is heat-treated for the first time
Profile temperature after being welded first time by press quenching technology rises to 800 ~ 1000 DEG C；
(4) fixed length flies saw
Profile after being heat-treated first time by cutting equipment is sawed into the profile of designated length；
(5) stretch bending
First the both ends of profile after sawing are heated, then are drawn at the both ends of profile by scheduled radian by stretch benders
It is curved；
6) it is heat-treated for second
Accessory is put into reheater and is heat-treated, accessory bulk temperature is made to rise to 800 ~ 1000 DEG C；
(7) it welds for second
Upper accessory is welded in the specified location of the profile after stretch bending, constitutes front lower portion assembly；
(8) antirust treatment
Front lower portion assembly is put into film in electrophoresis tank.
As a further improvement of that present invention, the steel band is rolled into the profile with designated shape, refers to using multiple groups
Rolling forging die squeezes steel band, and steel band is gradually become the profile with specified section configuration.Steel band is squeezed by rolling forging die,
Steel band continuous modification, gradually becomes the profile of required section, and the dimensional accuracy of profile can be controlled effectively.
As a further improvement of that present invention, described second welding uses manipulator, realizes accessory by manipulator
It clamps and puts.Using mechanical manual task, not only safety is protected, but also also improves the efficiency of operation.
As a further improvement of that present invention, the fixed length flies to be additionally provided with laser boring step between saw step and stretch bending step
Suddenly, the laser boring step, which refers to, gets several holes by laser in the appointed part of sawing profile.
It is simple that compared with the prior art, the advantages of the present invention are as follows steps, and the intensity of front lower portion assembly after molding is higher,
Compare traditional handicraft, and cost of labor of the invention is lower, high-efficient, highly-safe.In simple terms, after Overheating Treatment, energy
The effective intensity for improving protection crossbeam, effectively mitigation product weight.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention is carried out further detailed
Explanation.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not intended to limit the present invention.
Commercial vehicle front lower portion moulding process, comprising the following steps:
(1) it rolls, selects the steel band of specified specification as main material, be rolled into have by steel band by flow forming process and specify
The profile of shape；
(2) it welds for the first time, passes through the side welded closure of the profile after line welding technique is by rolling；
(3) it is heat-treated for the first time, the profile temperature after being welded first time by press quenching technology rises to 800 ~ 1000 DEG C；
(4) fixed length flies saw, and the profile after being heat-treated first time by cutting equipment is sawed into the profile of designated length；
(5) stretch bending first heats the both ends of profile after sawing, then scheduled radian is pressed at the both ends of profile by stretch benders
Carry out stretch bending；
6) it is heat-treated for second
Accessory is put into reheater and is heat-treated, accessory bulk temperature is made to rise to 800 ~ 1000 DEG C；
(7) it welds for second, welds upper accessory in the specified location of the profile after stretch bending, constitute front lower portion assembly；
(8) front lower portion assembly is put into film in electrophoresis tank by antirust treatment.
This processing step is simple, and the intensity of front lower portion assembly after molding is higher, and compare traditional handicraft, and cost of labor is more
It is low, it is high-efficient, highly-safe.In simple terms, after Overheating Treatment, the intensity of protection crossbeam can be effectively improved, is effectively mitigated
Product weight.
Steel band is rolled into the profile with designated shape, refers to and is squeezed using multiple groups rolling forging die steel band, by steel band
Gradually become the profile with specified section configuration.Steel band is squeezed by rolling forging die, steel band continuous modification is disconnected needed for gradually becoming
The dimensional accuracy of the profile in face, profile can be controlled effectively.
Second of welding uses manipulator, realizes the clamping of accessory by manipulator and puts.Made using manipulator
Industry, not only safety is protected, but also also improves the efficiency of operation.
Fixed length flies to be additionally provided with laser boring step between saw step and stretch bending step, and laser boring step refers in sawing type
Several holes are got by laser in the appointed part of material.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
