Problems solved by technology

The processing mold is usually composed of an upper mold and a lower mold. During the processing of the product, the upper mold and the lower mold need to perform multiple mold opening and closing operations, and each production must withstand a pressure of 10-15MPa for several hours. , so the processing mold will cause serious wear after long-term use, so that the product blank will be heated unevenly during the molding process, resulting in a large error between the produced product and the preset product, and will make the surface of the produced product rough and have burrs , affect the product quality, and also cause difficulties in the demoulding process of the product

Embodiment 1

[0018] A processing mold for automobile spring pads proposed by the present invention is cast from steel, and the steel includes raw materials in the following weight percentages: C 0.25%, Si 0.70%, Cr 0.45%, Mn 0.75%, V 0.65% , W 0.25%, Nb 0.15%, Cu 0.40%, Al 0.40%, rare earth metal 0.6%, MoS 2 1%, S 0.10%, the balance is Fe and unavoidable impurities.

[0019] Its processing method comprises the following steps:

[0020] S1. Preparation of molten steel for processing molds: raise the temperature of the melting furnace to 1950°C, and add ferrochrome to the melting furnace. After the ferrochrome is completely melted, the melting solution is tested, and pure iron is added to adjust the melting solution When the Fe content is above 80%, add the corresponding mass of V and Mn to the melting furnace, continue melting, then lower the temperature of the melting furnace to 1350°C, and then add the corresponding mass of Al, Cu and MoS 2 , raise the temperature of the smelting furna...

Abstract

The invention discloses a machining die for an automobile spring cushion. The machining die is formed by casting steel materials. The steel materials comprise C, Si, Cr, Mn, V, W, Nb, Cu, Al, rare earth metal, MoS2, S, Fe and inevitable impurities. A machining method of the machining die comprises the following steps that 1, ferrochromium is molten, the ingredient content is detected, V and Mn areadded, melting continues to be carried out, the temperature is reduced, Al, Cu and MoS2 are added, the temperature is rapidly increased to 3450-3550 DEG C, W, Nb and rare earth metal are added, inertgas is introduced, refining is carried out, and a steel material melt is obtained; and 2, casting, carburization, quenching, tempering, grinding, polishing and lubrication oil smearing for the steelmaterial melt are carried out, and therefore the finished product is obtained. The machining die is high in strength, good in toughness and cutting performance, excellent in wear resistance and corrosion resistance, and small in surface friction coefficient, and the machining method comprises the reasonable steps and is high in energy utilization rate and high in machining efficiency.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a processing mold for an automobile spring pad and a processing method thereof. Background technique [0002] There are many kinds of auto parts, and the processing mold is the most important tool in the production process of most auto parts, especially for auto parts made of rubber and plastic materials, usually the embryos required for product production must first be injected into the In the processing mold, and complete the molding process in the processing mold, and then separated from the processing mold, the semi-finished product of the product is obtained. Therefore, whether the product blank can be formed smoothly, whether the product with a predetermined shape can be produced, and whether the performance of the produced product meets the standard are all related to the processing mold used to produce the product. The processing mold is usually composed of an u...
