Most of the stainless steel sculptures are forging technology, so today we will talk about the method of forging stainless steel sculpture.
Simply put, the method of forging stainless steel sculpture is to use stainless steel plate cutting and cutting to assemble the designed pattern, and then carry out the process of welding polishing.
The most important part of stainless steel sculpture is sculpture design. Because most stainless steel sculptures are not concrete, most of them are abstract or semi-abstract sculptures. So how to design, how to combine stainless steel sculpture with design ideas, can’t just look for simple sculptures. Processing plants need to find a comprehensive sculpture company that integrates sculpture design and processing.
The professional sculpture company can combine the early sculpture design with the later sculpture processing and comprehensively consider it to achieve the best results.
- Cutting material: The general tool used is electric scissors, which can cut thin plates of 2mm or less, but the level of flatness after cutting is not good. There are also cutting machines, thick plates, thin plates can be cut, but can only cut the line, there is nothing to do when encountering the arc. To cut the stainless steel sheet into a flat and multi-shape, use a plasma cutter.
Plasma cutting machines can use high plasma to cut metals that are difficult to cut with conventional oxygen cutting methods. Since the current and gas are passed into a special nozzle cooled by water, a strong compression arc is generated to form a very high temperature (more than 10,000 degrees) plasma flow, so that the cut stainless steel sheet is neat and not deformed.
Note that the hand must be stable when cutting, otherwise the material will be cut. After the material has been cut, it is necessary to plan according to the shape required by the work. Do not leave any damage on the board surface, so as not to leave a flaw after polishing the work. The current sculptor company also uses the latest flame cutting and laser cutting methods.
2, forging: the stainless steel plate is taken to the mold and hit the ground to knock, according to the different shapes of each part of the model, the material is discharged, according to its fluctuation, consciously tapping, the bend of the place to bend, the place of the edge Knocking the edges, you can tap on any tangible solid object, then compare the knocked stainless steel plate to the mold, think that the shape is correct and can be completely closed with the model, and then take these scattered carbon steel plates and stainless steel plates from The upper and lower blocks are welded together, and each piece is adjusted to the mold. The texture of each stainless steel plate surface must be the same, which must be forged while being shaped. You can also forge the point and then cut it. When forging points, the round head of the hammer should be uniformly and regularly row-forged, and the width and the narrow distance should be the same.
- Forming: welding, grinding and painting. After the body is forged correctly, they must be welded together according to the requirements of the work (with electric welding and argon arc welding).
Stainless steel polishing firstly grinds the welds and extra places of the finished work with a grinding wheel, and then uses a soft wheel (cloth wheel) to cast it. When polishing, the work is coated with polishing paste to increase lubrication, so that the work is thrown brighter, thus giving People have a good visual aesthetic. Finally, spray automotive paint according to demand.
Carbon steel plate and stainless steel polishing Firstly use the grinding wheel to smooth the welds and extra places of the finished work, then use the soft wheel (cloth wheel) to cast. When polishing, the work is coated with polishing paste to increase lubrication, which makes the work more bright. , thus giving a good visual aesthetic. Larger, simple-looking stainless steel sculptures are also available without welding. The steel frame can be directly made according to the proportion of the work, and the electric drill can be used to make a hole in the designed position, and the stainless steel plate can be fixed on the skeleton with rivets.
This method requires that the scale of the skeleton be calculated very accurately, and the seams should be right, otherwise there will be differences that will not achieve the desired results.
- Visually inspect the workpiece transferred to the polishing process, such as whether the weld has leakage weld, weld penetration, uneven weld depth, too far from the joint, partial depression, misalignment, and deep drawing. Traces, bumps, severe deformation, etc., which cannot be remedied in this process. If any of the above defects are present, they should be returned to the previous process for trimming. If there is no such defect, enter the polishing process.
2, rough grinding, using 600# abrasive belt to grind the workpiece on three sides, the goal of this process is to remove the solder joint left by the workpiece welding, and the bumps in the previous step to reach the weld fillet Initially formed, the horizontal and vertical surfaces are basically free of large scratches and no bumps. After this step, the surface roughness of the workpiece should be R0.8mm. Pay attention to the angle of inclination of the belt machine during the polishing process and control the pressure of the belt machine on the workpiece. Generally speaking, it is more moderate in a straight line with the tossed face!
3, semi-finishing, using 800# abrasive belt to grind the workpiece in the front and back grinding the three sides of the workpiece, mainly to correct the joints appearing in the previous process and further fine-grain the impressions produced after the rough grinding The impression left on the previous process should be repeatedly ground to achieve no scratches on the surface of the workpiece, and it is basically bright. The surface roughness of this process should be able to reach R0.4mm.
- Fine grinding, using 1000# sanding belt is mainly to correct the grinding of the fine lines appearing in the previous step, and the grinding method is the same as the above. The goal to be achieved in this process is that the joint between the grinding part and the unground part of the workpiece is basically disappeared, and the surface of the workpiece is further brightened. The workpiece after grinding by this process is basically close to the mirror effect, and the surface roughness of the workpiece should reach R0. 1mm.
5, installation: generally welded, relatively firm, that is, the skeleton of the sculpture itself and the pre-embedded iron on the pedestal, pre-embedded iron under the welded steel, according to the size of the sculpture to determine the length of the steel and the size of the embedded iron. For the sake of beauty, after the sculpture is installed, the base will be pasted with marble or granite plates.
