Problems solved by technology

[0004] However, when the lubricating oil is lubricated between the rounded corners of the die, the blank and the die, the gravitational force or the downward inertia during the stamping and drawing process may cause the lubricating oil to flow down the surface of the die, thereby accumulating a large amount of lubricating oil. The oil forms oil pollution, which affects the use of drawing die equipment

Embodiment Construction

[0022] In this application, the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", "inner", "outer", "middle", The orientation or positional relationship indicated by "vertical", "horizontal", "horizontal", "longitudinal", etc. is based on the orientation or positional relationship shown in the drawings, and is only used to illustrate the relative positional relationship between components or components , does not specifically limit the specific installation orientation of each component or component.

[0023] Moreover, some of the above terms may be used to indicate other meanings besides orientation or positional relationship, for example, the term "upper" may also be used to indicate a certain attachment relationship or connection relationship in some cases. Those skilled in the art can understand the specific meanings of these terms in this application according to specific situations.

[0024] Furthermore, the terms "installed", "disposed", "provi...

Abstract

The invention discloses a deep drawing lower die which can guide and collect lubricating oil located on the upper surface of the lower die so as to reduce pollution formed by oil accumulation. The drawing lower die comprises a lower die body, at least three side groove bodies and a flow guide connector. The side groove bodies are embedded in the upper part of the lower die body, and are sequentially connected end to end to form a ring shape so as to surround and collect lubricating oil which is guided to the outer side in a deep drawing working area; the flow guide connector is located on one side of the lower die body and fixedly connected with the lower die body. A through hole is formed between the flow guide connector and the side groove body, and the height of any position of the bottom face of the through hole relative to the horizontal plane is lower than the height of the bottom of the side groove body relative to the horizontal plane so that lubricating oil in the side groove body can be guided to flow into external oil storage equipment in butt joint with the flow guide connector.

Description

technical field [0001] The present application relates to the field of deep drawing die equipment, in particular to a deep drawing lower die. Background technique [0002] Metal sheet deep drawing is a processing method that utilizes the plasticity of the metal sheet to make the sheet into parts through the external force stamping effect of the lower mold to fix the sheet and the upper mold. [0003] In the process of deep drawing and forming of sheet metal, lubricating oil is generally used to lubricate the rounded corners of the die, the blank and the die well, thereby reducing friction, reducing deep drawing force, increasing the ultimate deformation of the material, and reducing the limit The deep drawing coefficient, thereby improving the life of the die and the quality of the processed parts. [0004] However, when the lubricating oil is lubricated between the rounded corners of the die, the blank and the die, the gravitational force or the downward inertia during the...
