Universal combined type die forging tool

Abstract

The invention discloses a universal combined type die forging tool. The universal combined type die forging tool is composed of an upper press ring, an upper die sleeve, an upper transition sleeve, anupper die core, a lower press ring, a lower die sleeve, a lower transition sleeve, a lower die, a lower die core, an ejector rod and the like. The upper die sleeve is matched with the upper transition sleeve, the lower die sleeve is matched with the lower transition sleeve, the upper die sleeve and the lower die sleeve are used for positioning and fixing the upper transition sleeve and the lowertransition sleeve separately, the upper transition sleeve and the lower transition sleeve are used for positioning and fixing the upper die core and the lower die, a fastening pin is used for fastening and positioning the lower die, and the ejector rod ejects a formed forge piece out of a lower die cavity. The universal combined type die forging tool can be used for producing all parts below the production extreme dimension of a certain type of forging device and can well control the die manufacturing cost, and meanwhile has the characteristics of being convenient to mount and dismount, low inmaintenance cost, long in service life, good in interchangeability and the like.

Description

technical field [0001] The invention belongs to the field of hot forging tooling, in particular to a universal combined die forging tooling. Background technique [0002] The degree of die forging in the automobile industry is relatively high. For example, the planetary gears, sun gears, and differentials of automobiles are all produced by precision die forging, which is at the forefront of forging applications in China. There are also some companies in the weapon industry and aerospace industry that use precision die forging technology to produce forging blanks, and have achieved good economic benefits. However, compared with the automotive industry, the scale is generally small, mainly due to the variety of products, small batches, and high mold production costs. Objective factors such as poor mold interchangeability and inconvenient loading and unloading of molds restrict the application of forgings on presses. Therefore, in the process of processing and manufacturing, f...

Problems solved by technology

There are also some companies in the weapon industry and aerospace industry that use precision die forging technology to produce forging blanks, and have achieved good economic benefits. However, compared with the automotive industry, the scale is generally small, mainly due to the variety of products, small batches, and high mold production costs. Objective factors such as poor mold interchangeability and inconvenient loading and unloading of molds restrict the application of forgings on presses.

Therefore, in the process of processing and manufacturing, free forging or ordinary die forging technology is usually used. Compared with precision die forging, the microstructure and mechanical properties of forgings are lower, the machining allowance is large, the processing efficiency is low, the material utilization rate is low, and the manufacturing cost High, poor product surface quality

[0003] With the development requirements of lean production and green manufacturing, precision die forging technology has been developed. In addition to the tonnage limitation of the equipment itself, the mold cost and the traditional mold design method make only forgings with a small range of sizes suitable for a certain equipment, and equipment investment is also restricted. The development of precision die forging technology

[0004] Therefore, the traditional mold design method cannot be adopted, and problems such as mold production, maintenance cost, mold versatility, quick mold loading and unloading, and product size coverage must be solved
