tiene la capacidad de dise\u00f1ar y fabricar prensas de extrusi\u00f3n.&nbsp;<\/p>\n<p>Adem\u00e1s de la prensa mec\u00e1nica general, la prensa hidr\u00e1ulica, la prensa de extrusi\u00f3n en fr\u00edo, la prensa de fricci\u00f3n y los equipos de alta velocidad y alta energ\u00eda se han utilizado con \u00e9xito para la producci\u00f3n de extrusi\u00f3n dura.<\/p>\n<h2><strong><b>Defina<\/b><\/strong><\/h2>\n<p>La extrusi\u00f3n es un proceso que fuerza a las virutas de oro a producir <strong><b>flujo de pl\u00e1stico<\/b><\/strong> a trav\u00e9s del hueco entre el punz\u00f3n y la matriz o la salida de la matriz para fabricar las piezas huecas o las piezas cuya secci\u00f3n es menor que la secci\u00f3n de la pieza en bruto.Si la pieza en bruto se extruye sin calor, se denomina extrusi\u00f3n en fr\u00edo.La extrusi\u00f3n en fr\u00edo es una de las tecnolog\u00edas de transformaci\u00f3n de piezas sin viruta y con menos viruta, por lo que es una tecnolog\u00eda avanzada en la transformaci\u00f3n pl\u00e1stica de las virutas de oro. Si la pieza en bruto se prensa calent\u00e1ndola a una temperatura inferior a la de recristalizaci\u00f3n, se denomina extrusi\u00f3n en caliente. La extrusi\u00f3n en caliente sigue teniendo la ventaja de que hay menos virutas.<\/p>\n<h2><strong><b>Ventajas<\/b><\/strong><\/h2>\n<ol>\n<li><strong><b>Dimensionamiento preciso<\/b><\/strong><\/li>\n<\/ol>\n<p>La precisi\u00f3n dimensional general de las piezas extruidas en fr\u00edo desarrolladas en nuestro pa\u00eds es de hasta 8 ~ 9 grados. Si se utiliza una lubricaci\u00f3n ideal, s\u00f3lo es superada por la superficie de pulido fino. Por lo tanto, las piezas fabricadas por el m\u00e9todo de extrusi\u00f3n en fr\u00edo generalmente no necesitan ser repasadas, y un peque\u00f1o n\u00famero s\u00f3lo necesita ser acabado (rectificado). Ahorra materiales.<\/p>\n<ol start=\"2\">\n<li><strong><b>Ahorrar materiales<\/b><\/strong><\/li>\n<\/ol>\n<p>La tasa de utilizaci\u00f3n de materiales extruidos en fr\u00edo puede alcanzar normalmente m\u00e1s de 80%. Por ejemplo, la tasa de utilizaci\u00f3n del material de corte din\u00e1mico del pasador del pist\u00f3n del autom\u00f3vil de la marca Jiefang es de 43,3%, y con la extrusi\u00f3n en fr\u00edo la tasa de utilizaci\u00f3n del material aument\u00f3 a 92%; Por ejemplo, despu\u00e9s de cambiar el manguito del cojinete de la junta universal a extrusi\u00f3n en fr\u00edo, la tasa de utilizaci\u00f3n del material aument\u00f3 de 27,8% a 64%. Puede verse que el m\u00e9todo de extrusi\u00f3n en fr\u00edo puede ahorrar mucho acero y materiales met\u00e1licos no ferrosos en la producci\u00f3n de piezas de maquinaria<\/p>\n<ol start=\"3\">\n<li><strong><b>Alta eficiencia de producci\u00f3n<\/b><\/strong><\/li>\n<\/ol>\n<p>La eficacia de la producci\u00f3n de piezas mec\u00e1nicas por extrusi\u00f3n en fr\u00edo es muy alta, especialmente en la producci\u00f3n de piezas de grandes lotes. La producci\u00f3n por extrusi\u00f3n en fr\u00edo es varias veces, docenas de veces o incluso cientos de veces superior a la de corte. Por ejemplo, los pasadores de pist\u00f3n extruidos en fr\u00edo para autom\u00f3viles son 3,2 veces m\u00e1s productivos que los mecanizados, y actualmente se utilizan aut\u00f3matas de pasadores de pist\u00f3n extruidos en fr\u00edo para aumentar a\u00fan m\u00e1s la productividad. La productividad de un aut\u00f3mata de extrusi\u00f3n en fr\u00edo equivale a la de 100 tornos normales o 10 tornos autom\u00e1ticos de cuatro husillos.<\/p>\n<ol start=\"4\">\n<li><strong><b>Amplia aplicaci\u00f3n<\/b><\/strong><\/li>\n<\/ol>\n<p>Tales como secciones de forma especial, dientes internos, agujeros de forma especial y agujeros ciegos, Estas piezas son dif\u00edciles de completar con otros m\u00e9todos de procesamiento, pero es muy conveniente procesarlas con extrusi\u00f3n en fr\u00edo.<\/p>\n<ol start=\"5\">\n<li><strong><b>Alta resistencia<\/b><\/strong><\/li>\n<\/ol>\n<p>Debido a que la extrusi\u00f3n en fr\u00edo adopta la caracter\u00edstica de refuerzo por deformaci\u00f3n en fr\u00edo de los materiales met\u00e1licos, es decir, la pieza en bruto met\u00e1lica se encuentra en un estado de tensi\u00f3n de compresi\u00f3n de tres v\u00edas durante el proceso de extrusi\u00f3n, y el material es compacto y tiene una direcci\u00f3n de flujo de fibra continua despu\u00e9s de la deformaci\u00f3n, por lo que la resistencia de las piezas mejora considerablemente. De este modo, se pueden utilizar materiales de baja resistencia en lugar de materiales de alta resistencia. Por ejemplo, en el pasado, el acero 20Cr se utilizaba para fabricar pasadores de pist\u00f3n de marca de liberaci\u00f3n por corte. Ahora, el acero 20 se utiliza para fabricar pasadores de pist\u00f3n por extrusi\u00f3n en fr\u00edo. Tras la prueba de rendimiento, el m\u00e9todo de extrusi\u00f3n en fr\u00edo es superior al de corte para fabricar pasadores de pist\u00f3n.<\/p>\n<p>Si tiene alguna necesidad de extrusi\u00f3n en

Details Cold extrusion is to put the metal blank in the cold extrusion cavity, at room temperature, through the press fixed punch to apply pressure to the blank, so that the metal blank to produce plastic deformation and parts processing method. China has been able to cold extrusion of lead, tin, aluminum, copper, zinc and their alloys, low carbon steel, medium carbon steel, tool steel, low alloy steel, and stainless steel, and even bearing steel, high carbon and high aluminum alloy tool steel, high-speed steel, and other metals can be cold extrusion of a certain amount of deformation.In extrusion equipment, our country has the ability to design and manufacture extrusion presses.&nbsp; In addition to the general mechanical press, hydraulic press, cold extrusion press, friction press,, and high-speed high-energy equipment have been successfully used for hard extrusion production. Define Extrusion is a process that forces the gold chips to produce plastic flow through the gap between the punch and the die or the die outlet to make the hollow parts or the parts whose section is smaller than the blank section.If the blank is extruded without heat, it is called cold extrusion.Cold extrusion is one of the processing technology of no chip and less chip parts, so it is an advanced technology in the plastic processing of gold chips. If the blank is pressed by heating it to a temperature below the recrystallization temperature, it is called warm extrusion. Warm extrusion still has the advantage of fewer chips. Advantages Accurate sizing The general dimension accuracy of cold extruded parts developed in our country is up to 8 ~ 9 grades. If ideal lubrication is used, it is second only to the fine polishing surface. Therefore, parts manufactured by the cold extrusion method generally do not need to be reworked, and a small number only need to be finished (grinding). Save materials. Save materials The utilization rate of cold extruded materials can usually reach more than 80%. Such as the Jiefang brand automobile piston pin dynamic cutting material utilization rate of 43.3%, and with cold extrusion material utilization rate increased to 92%; For example, after the universal joint bearing sleeve is changed to cold extrusion, the material utilization rate is increased from 27.8% to 64%. It can be seen that the cold extrusion method can save a lot of steel and non-ferrous metal materials in the production of machine parts High production efficiency The efficiency of producing mechanical parts by cold extrusion is very high, especially in the production of large batch parts. The production by cold extrusion is several times, dozens of times, or even hundreds of times as compared with cutting. For example, cold-extruded piston pins for automobiles are 3.2 times more productive than machined ones, and cold-extruded piston pin automatons are now used to further increase productivity. The productivity of one cold extrusion automaton is equivalent to that of 100 regular lathes or 10 four-spindle automatic lathes. Wide application Such as special-shaped sections, internal teeth, special-shaped holes, and blind holes, These parts are difficult to complete by other processing methods, but it is very convenient to process with cold extrusion. High strength Because the cold extrusion adopts the cold deformation strengthening characteristic of metal materials, that is, the metal blank is in the state of three-way compressive stress during the extrusion process, and the material is compact and has continuous fiber flow direction after deformation, so the strength of the parts is greatly improved. In this way, low-strength materials can be used instead of high-strength materials. For example, in the past, 20Cr steel was used to manufacture liberation brand piston pins by cutting. Now, 20 steel is used to manufacture piston pins by cold extrusion. After the performance test, the cold extrusion method is higher than the cutting method to manufacture piston pins.
