Example 1
As shown in fig. 1-7, a tailor welding process of a light conduction box, the light conduction box includes a bottom plate 1 and a top plate 5, an inclined support 2 for installing a mirror assembly is welded on the bottom plate 1, one end of the inclined support 2 is welded with the bottom plate 1, and the other end of the inclined support 2 is welded with a rear frame 6; the two sides of the inclined strut member 2 are respectively welded on the left side plate 8 and the right side plate 3; a front frame 4 is welded on the bottom plate 1; the rear frame 6, the front frame 4, the left side plate 8, the right side plate 3, the bottom plate 1 and the top plate 5 are mutually welded in pairs; the method comprises the following steps:
s1: welding parts; welding and fixing the bottom plate 1, the inclined supporting piece 2, the rear frame 6, the left side plate 8 and the right side plate 3 in pairs to form a semi-finished product;
s2: carrying out first heat treatment; carrying out heat treatment on the semi-finished product to eliminate welding stress;
s3: welding; welding a front frame 4 and a rear frame 6 on the basis of the semi-finished product subjected to heat treatment to form a light-conducting box;
s4: and the second heat treatment is carried out on the light conduction box for eliminating the welding stress.
Specifically, in this embodiment, the inclined strut member 2 is welded between the bottom plate, the rear frame 6, the left side plate 8 and the right side plate 3, the bottom plate 1 and the rear frame 6 and the inclined strut member 2 form a triangular structure, and the butt joint position 9 between the left side plate 8 or the right side plate 3 and the bottom plate 1, the inclined strut member 2 and the rear frame 6 forms a triangular structure, so that mutual constraint between each part of the light conduction box is structurally improved, thereby ensuring the dimensional stability of the light conduction box under the condition of long-term use, and further ensuring the stable installation position of the reflective mirror.
Further, in the embodiment, the light guide box is divided into two welding steps and two heat treatments, and the first heat treatment of the step S2 eliminates the welding stress existing in the tailor-welded part of the step S1; step S4, second heat treatment is to eliminate welding stress existing in the welding in the step S3; the welding stress is eliminated successively, so that overlarge size change caused by stress accumulation in the welding process is avoided, and the purpose of reducing process errors is achieved; the deformation of the shape and the size of the light conduction box after heat treatment can reach the requirement of less than one thousandth, or the dimensional tolerance and the form and position tolerance can reach the requirement of less than 1 mm.
It should be noted that, in step S1, at least the bottom plate 1, the cross brace 2, the rear frame 6, the left side plate 8 and the right side plate 3 are welded, because the above parts are essential parts for fixing the cross brace 2 and stabilizing the brace 7, if there is only one part welded, there is a direction of free deformation between the parts during the heat treatment process, so that the purpose of mutual constraint cannot be achieved, and the requirement of stable size cannot be met.
To be further described, in the present embodiment, in step S1, the bottom portion should be welded in advance, and if the bottom portion includes the bottom plate 1 and the supporting legs, the bottom plate 1 and the supporting legs should be welded in advance; and after the bottom welding is finished, the mounting positions of other follow-up parts are machined, so that higher combination precision is formed, the integral deformation after the direct splicing welding can be effectively reduced, and the same mounting reference is provided for the mounting welding of other parts mounted on the bottom.
In the present embodiment, the welding sequence in step S3 is to weld the front frame 4 and then weld the top plate 5, so that the top plate 5 can be supported during assembly, thereby achieving the purpose of reducing the variation in the installation dimension of the top plate 5.
Example 2
On the basis of example 1, a practical embodiment is further proposed.
In an optional specific implementation manner, before the step S1 is performed, each part needs to be cleaned, and mainly residues, impurities and oil stains on the surface of the part are cleaned, so that defects of inclusions, air holes and the like in the assembling and welding process of the part are reduced; specifically, in the welding process, residues and impurities on the surface of the part can enter the welding position, so that impurities appear in the welding position; oil contamination into the weld site can cause blistering of the weld site.
In the embodiment, an organic solvent (such as absolute ethyl alcohol) is adopted to remove oil stains, and nylon soft hair brushes, brush rollers and the like are used for brushing the surface of the part; and then spraying clear water to the cleaning position in a high-pressure spraying mode, and air-drying to finish the cleaning of the surface of the part. The beneficial effects of using absolute ethyl alcohol as an organic solvent to remove oil stains include at least the following: firstly, the absolute ethyl alcohol is volatile, so that the surface of the part is not worried about residue; secondly, the absolute ethyl alcohol can be mixed with water in any proportion, so that the aim of easy removal during part surface cleaning is fulfilled. And secondly, the output pressure of the high-pressure spraying is more than 15Mpa, so that residues and impurities on the surface of the part can be effectively removed.
In an alternative embodiment, after step S2 is completed, step S21 is performed: correcting the shape; performing shape correction on the semi-finished product according to the data requirement; the shape correcting process is a prediction process and mainly corrects the shape and position tolerance (such as verticality, planeness, straightness and the like) exceeding the requirement of the designed deformation; if not, no correction is needed.
In the present embodiment, if the shape correction is required, the shape correction in step S21 must be performed after the first heat treatment in step S2 is completed; specifically, the shape correction process is arranged after the first heat treatment in step S2 in order to cause an excessive change in the shape of the part during the recovery heat treatment; that is, if the shape correction in step S21 is performed before the first heat treatment in step S2, the shape correction process is restored to the design requirement of the form and position tolerance, but the material is deformed under the action of high temperature, and a small deformation generated at the butt joint position 9 during the welding stress relief may be superimposed on the deformation generated in the shape correction process, so that the deformation amount is uncontrollable; therefore, the step S21 sizing must be performed after the step S2 first heat treatment is completed.
In an alternative embodiment, as shown in fig. 1-3, after step S21 is completed, a support 7 for supporting the mirror assembly is mounted on the cross support 2, the support 7 is a part for mounting the mirror assembly, the support 7 is mounted on the cross support 2, and the form and position tolerance of the cross support 2 is essential for ensuring the position of the support 7, and further essential for ensuring the accuracy of the mounting position of the mirror assembly, so the process of mounting the support 7 on the cross support 2 should be after the shaping process.
According to an optional specific embodiment, after the support 7 is installed, the installation reference and the support surface of the reflector assembly of the support 7 are subjected to numerical milling, the numerical milling is to conduct the numerical milling on the support 7, a numerical control five-axis machine tool is adopted to be machined in place at one time, the required angle error is smaller than 10 milliradians, the position error is smaller than 0.07mm, the planeness is smaller than 0.05mm, and the accuracy and the precision of the installation position of the reflector assembly are guaranteed.
It should be noted that, in step S1 and step S2, the advantage of not assembling the front frame 4 and the top plate 5 is that it is convenient for the milling head to process several milling positions when milling the support 7, and the effect of blocking the cutter is avoided.
An optional specific implementation manner, in step S1 and step S3, the welding mode adopts laser welding, the material of the part is aluminum alloy, the deformation easily appears during the welding process and after the welding, and the assembly precision is affected, therefore, the solution to this problem benefits from the embodiment of adopting laser welding, the laser welding can form good defect-free, the mechanical property is close to that of wood, and the laser welding has obvious advantages compared with argon arc welding in terms of welding residual stress, welding efficiency and welding deformation.
An alternative embodiment is shown in fig. 4, before step S1 and step S3, welding is performed after the prefabrication and butt joint step is completed, that is, the prefabrication and butt joint is performed by using pins to perform prefabrication and butt joint on each part, and normal temperature curing resin glue is coated on a butt joint combination interface (i.e., a butt joint position 9, which is a position enclosed by a rectangular frame in fig. 4); in the embodiment, an auxiliary tool is not selected to additionally constrain and fix the part, the corresponding part precision is made to meet the design requirement (generally, IT 6) before welding, pins for butt joint are prefabricated, the tool is matched with the pin to form a qualified size by utilizing the higher precision of the pin as much as possible, and the purposes of saving cost and improving efficiency are achieved.
Specifically, before step S1 and step S3, a normal temperature curing resin adhesive, such as a DG-3 resin adhesive, is coated on the butt joint position 9 of the part and the part; positioning and pre-installing by using a pin, checking the size, removing redundant normal-temperature cured resin adhesive after the normal-temperature cured resin adhesive is cured, cleaning a welding groove, and waiting for welding; the pin is matched with the pin hole 10 to realize positioning; as shown in fig. 4, the front frame 4 and the top plate 5 are prefabricated to be butted when they are welded.
According to an optional specific implementation mode, after the prefabricated butt joint step is completed, welding between parts is completed within 3h, and the situation that the performance of the material is reduced due to excessive oxidation of the welding groove position is avoided.
In step S1 and step S3, the welding type during the butt joint of the parts is any one of symmetric fillet welding, symmetric butt welding and asymmetric composite welding, the welding type is selected according to the situation, the three welding types are adopted to carry out the butt joint welding on the parts, the deformation caused by overlarge welding stress during the local welding can be effectively controlled, and the result is obtained through a large number of process tests.
Specifically, if two parts are vertically butted and the two sides of one part are provided with the material of the other part, symmetrical fillet welding is preferably adopted, and symmetrical fillet welding (a first welding seam 11 and a second welding seam 12) is synchronously performed, as shown in fig. 5; if the two parts are butted in the parallel direction, symmetrical butt welding is preferably adopted, and symmetrical butt welding (a third welding line 13 and a fourth welding line 14) is synchronously performed, as shown in fig. 6; if the two parts are butted vertically and there is material on only one side between the two parts, it is preferred to use asymmetric hybrid welding, i.e. fillet welding (weld five 15) is performed first, the fillet welding being on the side with material, and butt welding (weld six 16) is performed again, the butt welding being on the side without material, as shown in fig. 7.
Furthermore, the diameter of the welding wire for welding is selected to be 1.2mm-1.6mm, the width of a light spot is 2.5mm-3.5mm, and the welding speed is 30mm/min-40mm/min; specifically, the diameter of the welding wire for butt welding should be 1.6mm in the embodiment, the width of the light spot should be 3.5mm, and the welding speed should be 40mm/min; the diameter of a welding wire for fillet welding is 1.2mm, the width of a light plate is 2.5-3mm, and the welding speed is 30mm/min.
Further, the filling capacity is poor due to the fact that the diameter of the welding wire is too small, the situation that two or more times of fusion welding are needed is easy to occur in the welding process, so that welding stress and deformation can be improved, the bending radius is large due to the fact that the diameter of the welding wire is too large, and automatic wire feeding cannot be achieved; the welding wire diameter within the range is selected to complete the filling of the welding seam at one time, so that the welding defect caused by multiple times of welding is avoided; the width of the light spot is too large, the laser energy is dispersed, so that the depth of the welding seam is reduced, the width of the light spot is too small, the laser energy is too concentrated, the depth of the welding seam is too large, and the welding effect can be ensured in the aluminum alloy material by using the width of the light spot; the welding speed can affect the welding width and the depth of a welding seam, and when the welding speed is too low, gas or water molecules in the environment can enter a material in a molten state to form air holes, so that the welding quality is affected; welding speed is too big, and welding width and welding depth are not up to standard, and the part butt joint is unstable, leads to the part to connect unstably, so, selects this welding speed can effectively guarantee welding quality.
In an alternative embodiment, the material of the part of the light-conducting box is aluminum alloy 6061-T6 or/and aluminum alloy 5A06; in the step S2 or S4, aiming at the aluminum alloy 6061-T6, the heat treatment mode is heating to 140-145 ℃, keeping the temperature for 235-245 min, and then discharging from the furnace for air cooling; or raising the temperature of the aluminum alloy 5A06 along with the furnace, preserving the heat for 1 to 1.5 hours at the temperature of between 310 and 330 ℃, and discharging the aluminum alloy from the furnace for air cooling after the heat preservation is finished; the heat preservation temperature is too low or/and the heat preservation time is too short, the welding stress can not be released or is not fully released, and the effect of removing the welding stress can not be achieved; the metal phase of the material is changed due to the overhigh heat preservation temperature, so that the performance of the material is influenced; too long a holding time will increase the production cost.
The invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification and any novel method or process steps or any novel combination of features disclosed.
