Industrial metal stamping machine is an important machine in metal forming production and is in great demand in the market. Nowadays, it is not easy to choose a good industrial metal stamping machine, because the manufacturing level of various industrial metal stamping machine manufacturers varies. Today we will take you through the main factors that influence industrial metal stamping machine.
An industrial metal stamping machine is a precision machine, because the accuracy of a punching machine is usually indicated by the accuracy of each part of the punching machine, because any error in one part will magnify the accuracy of the punching machine by a multiple.
The industrial metal stamping machine is driven by an electric motor, which charges the flywheel, which transmits the force to the crankshaft, which converts the force of circular motion into a force of vertical motion, and this force pushes the ram to complete the work, thus processing the workpiece. The accuracy of the industrial metal stamping machine body starts with the material of the body, and the body of the press provides support, fixation and stability for the proper operation of the press.
The rigidity and stability of the body is a major influence on the accuracy of the press. Punching bodies are usually processed by both steel plate welding and steel casting processes, and stress relief is required regardless of the method of handling the body. Part of stress relief is to ensure the overall strength of the welded body and that the welds are less likely to break, which also makes the body easier to machine. The advantage of welded steel plate bodies is that they are welded using steel plates. It is more flexible, easier to handle than casting, and easier to meet the custom requirements of non-standard users. Open type punching machines usually have C-shapes welded to the rails and the steel is cast to ensure its strength. Since certain large tonnage punches cannot be cast, steel plate welded bodies are mainly used for large tonnage punches, including some low speed precision punches, and the cast steel body is made by die casting and formed in one piece. Due to the casting process, a more special structure is obtained internally, which makes the absorption of resonance stronger than that of the welded steel body, and the stability is stronger than that of the welded steel body due to the integral molding.
The industrial metal stamping machine is affected by the processing technology and the difficulty of post-processing, the cast body can only be used for small tonnage punches and high-speed precision punches, and the cast steel body is built. In terms of accuracy only, both types of bodies can guarantee the required accuracy of the machine, which is only due to their respective special properties that make them different in the scope of application.
The quality of the assembly process directly determines the accuracy of the industrial metal stamping machine.
Fifty percent of the success or failure of an industrial metal stamping machine is due to the assembly process, the final assembly requires the combination of all precision parts into one part, and there is no guarantee that each part will have 100 absolute precision. If the allowable error of the slider is 2 and the allowable error of the crankshaft is 3, then their combined error is not 2 + 3, but 2 * 3 then the final error is 6. If the error is 2 if the total error generated during the assembly process will be 12, then the slight error generated during the assembly process will multiply the total error and will also reduce the accuracy of the punch.
The stamping and forming process generates a lot of heat during the stamping process, and this heat can deform the workpiece, thus seriously affecting the accuracy of the workpiece. Therefore, when selecting the die press oil, it is important to consider both the lubrication and cooling properties as well as the extreme pressure and anti-wear properties of the die press oil. If the selected extreme pressure and anti-wear properties are too low, the material may lead to poor forming effect. Therefore, for fine stamping or ultra-precision stamping, a stamping oil with good extreme pressure and anti-wear properties should be selected to properly maintain the industrial metal stamping machine.
The material of the body of industrial metal stamping machine is the most important factor to ensure the accuracy.
The mechanical punch usually uses gears and drive shafts for transmission, so the mechanical machining accuracy of gears and concentricity of shafts, mechanical machining accuracy of shaft holes, accuracy of bearing bushings and wear resistance are also important factors that affect the punching accuracy. The strength, rigidity and wear resistance of the crankshaft are ensured by grinding with a crankshaft precision grinder, then hard chromium plating and nitriding. The opening punch is usually two guide rails. The guide rail is V-shaped and rectangular, V-shaped guide also known as four side guide, the guide has four contact surfaces, rectangular guide also known as six-sided guide, the guide has six contact surfaces, all guide planes are precision ground using a guide grinder, in the assembly process, using a lever table for measurement, and scraping process to ensure its matching accuracy, closed industrial metal The main factors affecting the accuracy of the slider and the guide are the machining accuracy and the assembly process, and the slider balancing device.
Industrial metal stamping machine processing, slider down, after the work is completed, it will be subject to the reaction force of the mold. The reaction force and accuracy error of the guide rail will lead to slight change of the slider trajectory, after installing the slider balancing device, the slider and guide rail can keep parallel operation, the accuracy of the slider and the bottom surface of the table, the upper mold of the die is installed on the lower surface of the slider, the lower mold and other inlet and outlet equipment are installed on the table, the material of the two working platforms is made of cast steel or forged steel plate, after casting, first use the milling machine for milling, then use the surface grinder for grinding to ensure the accuracy of the slider. Then use surface grinder for grinding to ensure accuracy. When assembling, it is necessary to use instruments to measure, find errors and scrape in time for adjustment, punch to install environment and vibration dampening feet, large tonnage punches, precision punches and high speed punches need to be installed by casting anti-vibration pits during the installation process. Different punches are injected depending on the location of the mounting pins, and small punches are usually fitted with anti-vibration feet.
The maintenance condition of the industrial metal stamping machine also affects the accuracy of its precision. Good maintenance can restore and maintain its high accuracy, which is very important for the normal production of the enterprise.
