With the rapid development of technology, advertising has become an inseparable lifestyle in people's lifestyles. People are actively or passively accepting advertisements from around the world every day. Domestic and foreign advertising machines are no strangers to us. Various types of communities, shopping malls, elevators, stations, airports, buses, etc. have been popularized. Billboards, TV commercials, mobile advertisements, etc. have been deeply rooted in the hearts of the people. The promotional content of various types of advertising machines has imperceptibly affected people's shopping concept. As an accessory equipment manufacturer for the outer frame of the advertising machine, what is the process flow of Senseway Technology today to understand the outer casing of the advertising machine?
Senseway Ruikepu: Introduction to the process flow of the advertising machine shell
1. Workpiece blanking
After the drawings are handed, different blanking methods are selected according to the expansion drawing and batch quantity, including laser, CNC punching, shearing, mold, etc., and then according to the drawings to make corresponding expansion. CNC punching machine is affected by the tool. For the machining of some irregular workpieces and irregular holes, large burrs will appear at the edge, and the deburring process will be carried out at the same time, and the accuracy of the workpiece will be affected at the same time. Restricted, flat section, suitable for the machining of shaped workpieces, but it takes a long time to process small workpieces. Place the workbench next to the CNC and the laser to facilitate the placement of the sheet on the machine for processing, reducing the workload of the lift. Some of the available edge material is placed in a designated place to provide material for the test mode when bending.
After the workpiece is blanked, the corners, burrs, and joints must be trimmed (grinding). At the tool joint, the flat boring tool is used for dressing. For the larger burr workpiece, the grinding machine is used for dressing, and the small bore joint is at the joint. It is trimmed with the corresponding small trowel to ensure the appearance of the appearance. At the same time, the trimming of the shape is also ensured for the positioning during bending, so that the position of the workpiece on the bending machine is consistent when bending, and the size of the same batch of products is guaranteed.
2. Next process
After the blanking is completed, the next process is entered, and different workpieces enter the corresponding process according to the processing requirements. There are bending, riveting, flanging, spot welding, convex hull, step difference, sometimes the nut or stud should be pressed after bending one or two times, where the mold is convex and the difference is considered. First processing, so as to avoid interference in other processes after processing, can not complete the required processing. When there is a hook on the upper cover or the lower case, if it cannot be welded after bending, it should be processed before bending.
When bending, it is necessary to first determine the tool and the sipe used for bending according to the size and material thickness on the drawing, so as to avoid the collision between the product and the tool, which is the key to the selection of the upper mold (in the same product, it may be used) The upper die of different models), the selection of the lower die is determined according to the thickness of the plate. The second is to determine the order of bending, the general rule of bending is first inside and outside, first small and then large, first special and then ordinary. The workpiece to be crushed is first bent to 30°-40°, and then the workpiece is crushed by the flattening die.
When riveting, the same height of the stud should be considered, and then the pressure of the press should be adjusted to ensure that the stud and the surface of the workpiece are flush, so that the stud is not pressed or pressed out of the workpiece surface, resulting in the workpiece. scrapped.
Welding with argon arc welding, spot welding, carbon dioxide protection welding, manual arc welding, etc., spot welding must first consider the position of the workpiece welding, in the mass production, consider positioning tooling to ensure accurate spot welding position.
In order to weld firmly, the bumps on the workpiece to be welded can make the bumps evenly contact with the flat plate before the electric welding, so as to ensure the uniform heating of the points, and also determine the welding position. Similarly, the welding is required. Adjust the preloading time, holding time, maintaining time, and rest time to ensure that the workpiece can be spot welded firmly.
After spot welding, there will be weld defects on the surface of the workpiece, which should be treated by a flat mill. The sub-arc welding is mainly used when the two workpieces are large, and when they are connected together, or the corners of a workpiece are processed to achieve the smoothness of the surface of the workpiece. ,smooth. The heat generated by the argon arc is easy to deform the workpiece, and is treated by a sander and a flat mill after welding, especially in the corners.
3. Surface treatment
After the workpiece is bent, the riveting and other processes are completed, the surface treatment is carried out. The surface treatment of different plates is different. After the cold plate processing, the surface plating is generally performed. After the plating, the spraying process is not performed, and the phosphating treatment is adopted. Spray treatment after the treatment. The plated surface is cleaned, degreased, and then sprayed. Stainless steel plate (with mirror panel, fog panel, drawing plate) can be drawn before bending, without spraying, if it needs to be sprayed, it should be treated with hair; aluminum plate is generally treated with oxidation, and different colors are selected according to different colors of spraying. Oxidation background color, commonly used in black and natural oxidation; aluminum plate to be sprayed after chromate oxidation treatment. The surface pretreatment can make the cleaning surface significantly improve the adhesion of the coating film and double the corrosion resistance of the coating film. The cleaning process first cleans the workpiece, first hangs the workpiece on the assembly line, first through the cleaning solution (alloy de-oil powder), then into the clean water, then through the spray zone, then through the drying zone, and finally the workpiece from the assembly line Take it down.
4. Spray treatment
After the surface is pre-treated, it enters the spraying process, and the teeth or part of the conductive holes need to be protected when the workpiece is required to be assembled after spraying.
Protect the treated dental hole by checking the soft glue stick or screwing in the screw. If the conductive protection is required, it should be attached with high-temperature tape, and the large-scale positioning tool should be used for positioning and protection, so that it will not spray into the workpiece inside the workpiece, and the outer surface of the workpiece will be sprayed. The nut (flange) hole that can be seen is protected by screws to avoid the need to return the tooth at the workpiece nut (flanged) hole after spraying.
Some large-volume workpieces are also protected by tooling; when the workpiece is not assembled, the area that does not need to be sprayed is protected by high-temperature tape and paper sheets. Some exposed nut holes are protected by screws or high-temperature rubber. If the workpiece is sprayed on both sides, the nut (stud) hole is protected in the same way; the small workpiece is sprayed with the lead wire or the paper clip and the like; some workpieces have high surface requirements, and the workpiece is grounded before spraying; some workpieces are grounded. The symbol is protected by a special high temperature sticker.
When spraying, the workpiece is first hung on the assembly line, and the dust on the surface is blown off with a gas pipe. Into the spraying area, spray, after the spraying, enter the drying area along the assembly line, and finally remove the sprayed workpiece from the assembly line. Spraying is divided into manual spraying and automatic spraying. Manual spraying or semi-automatic dispensing machine can be used for spraying operation. Automatic spraying can be used for the frame coating machine
of Senseway advertising machine to meet different process requirements.
5. Assembly process
After spraying, enter the assembly process. Before assembly, remove the protective sticker used in the original spraying, and make sure that the threaded hole in the part is not sprinkled with paint or powder. Wear gloves to avoid dust on the hand during the whole process. On the workpiece, some of the workpieces are also blown clean with an air gun.
6. Packaging link
After assembly, the product enters the packaging process. After the workpiece is inspected, it is placed in a special packaging bag for protection. Some workpieces without special packaging are packaged with a bubble film or the like. Before packaging, the bubble film is cut into the size of the workpiece that can be packaged, so as not to cut the side of the package, which affects the processing speed; the large-sized can be customized special carton or bubble bag, rubber pad, tray, wooden box and so on. After packaging, put it into the carton, and then put the corresponding finished or semi-finished label on the carton.
After the above process, the metal casing process of the advertising machine is completed, and the advertising machine casing is beautiful and durable, will the mood be better?
