Self-oil-feeding type punching-mold guide component and punching mold

Abstract

The invention provides a self-oil-feeding type punching-mold guide component and a punching mold and relates to the technical field of punching of rigid equipment or tools. By adoption of the self-oil-feeding type punching-mold guide component and the punching mold, the technical problem of how to feed oil for lubrication automatically on a guide sliding surface is solved. The self-oil-feeding type punching-mold guide component comprises an upper mold and a lower mold, wherein the contact surfaces of the upper mold and the lower mold are matched. The self-oil-feeding type punching-mold guide component also comprises an oil feeding device, wherein a stopping block is fixedly arranged on the side wall of the upper mold; an oil discharging groove, an oil dispersing groove and a lubricating oil groove communicated in sequence from top to bottom are arranged on the guiding sliding surface of the lower mold; the oil feeding device and the stopping block are arranged at the same side, are fixedly arranged on the side wall of the lower mold, and are respectively connected and communicated with the oil discharging groove and an oil tank for storing oil by pipelines; the stopping block can drive the oil feeding device to convey the oil from the oil tank to the oil discharging groove in the moving process of the upper mold and the lower mold, so that the oil flows through the oil dispersing groove and the lubricating oil groove to further realize self-oil-feeding lubrication.

Description

technical field [0001] The invention relates to the technical field of punching with rigid equipment or tools, in particular to a self-oil-supported punching die guide assembly and a punching die. Background technique [0002] In the stamping production process of automobile panels or other parts, the wedge guide plate of the stamping die is often used to drive the flanging shaping mechanism. The wear of the guiding sliding surface will easily cause the stroke of the flanging shaping mechanism to be out of place, thus affecting the surface quality of the parts and full size pass rate. [0003] In the existing production process, the method of embedding solid lubricants, such as graphite columns, on the guide sliding surface relies on the continuous loss of the lubricant itself during work to achieve self-lubrication. However, the self-lubricating and heat-dissipating performance of this method is insufficient, which is prone to roughening and severe wear, which will reduce ...
