Stretching and shaping mould for producing automobile steel plate transmission wheel

Abstract

The invention discloses a stretching and shaping mold for producing an automobile steel plate transmission wheel. The stretching and shaping mold comprises a mold working table for producing the automobile steel plate transmission wheel, a mold machining body and a multi-stage adjustable stretching device are arranged above the mold working table, and the multi-stage adjustable stretching device is disposed inside the mold machining body. The mold machining body is further internally provided with a cooling forming device and a pre-lubricating device, the function of multi-stage stretching adjustment in the process of machining the automobile steel plate transmission wheel is realized, so that the mold can produce automobile steel plate transmission wheels with different structures, and the practicability of the mold is enhanced. A water-cooled cooling molding method can directly cool the surface of a product in a machining forming cavity, and the surface of the product is uniformly cooled, so that the problem that the damage caused to the product during extrusion of the product due to the inconsistent up and down molding speed of the product is avoided. The speed of cooling and forming of the product is improved, and therefore the production efficiency of the steel plate transmission wheel is improved.

Description

technical field [0001] The invention relates to the technical field of production of automobile parts, in particular to a stretching and shaping die for production of automobile steel plate transmission wheels. Background technique [0002] The power transmission device between the automobile engine and the driving wheel is called the transmission system of the automobile. It should ensure that the automobile has the necessary traction force and vehicle speed under various driving conditions, and ensure the coordination between traction force and vehicle speed. [0003] In the prior art, there are many deficiencies in the molds for producing automobile steel plate transmission wheels: [0004] (1) When multi-stage stretching, the stretching length of the next stage cannot be adjusted, and another mold needs to be opened, which greatly increases the production cost and makes the practical performance of the existing mold poor; [0005] (2) The cooling molding of existing for...

AI Technical Summary

Problems solved by technology

[0004] (1) When multi-stage stretching, the stretching length of the next stage cannot be adjusted, and another mold needs to be opened, which greatly increases the production cost and makes the practical performance of the existing mold poor;

[0005] (2) The cooling molding of existing forming molds is usually completed by natural cooling, and the time spent in the entire product molding process is relatively long, which makes the production efficiency of the product low. The products in the mold are blown and molded, but when the fan is used for blowing and cooling, only the upper surface of the product in the mold can be blown. Therefore, there are often cases where the upper part of the product is cooled and formed, but the lower part of the product is not cooled and formed. If Taking the product out of the mold at this time will cause damage to the product and increase the reject rate of the product
