METHOD, MOULD AND SYSTEM FOR MANUFACTURING MECHANICAL PART

摘要

Disclosed are a method, a mould and a system for manufacturing a mechanical part, utilizing a hot pressing process to manufacture the mechanical part. The method comprises the steps of: heating a steel blank sheet at a predetermined heating temperature, putting the steel blank sheet in the mould of the mechanical part and then pressing the sheet such that wrinkles are formed on the steel blank sheet at rounded corners of the mould and a mechanical part is formed in the mould. The mould of the mechanical part comprises a concave mould (701) and a convex mould (702), with a pressing gap (703) for accommodating the steel blank sheet being provided between the concave mould and the convex mould, and the width of the pressing gap at the rounded corners of the mould being larger than the thickness of the wrinkles. The mould and the system are produced by utilizing the above-mentioned method. The above-mentioned technical solution can prevent the steel sheet from being broken when the steel sheet is pressed continuously due to the irregular accumulation of the wrinkles, such that the solution has the advantages of decreasing the amount of broken products during production, lowering the rejection rate of products, lowering the production costs, and reducing resource consumption of iron and steel.
