Platform pressing mold for steel pipe surfaces

Abstract

The invention discloses a platform pressing mold for steel pipe surfaces. The platform pressing mold comprises a base, a lower die, an upper die, a mandrel component, an upper die plate and a pressing head. The lower die is provided with a lower die cavity. The mandrel component comprises a positioning seat and a mandrel. The positioning seat is fixed on the base and provided with a vertical mounting groove. The mandrel is vertically and elastically mounted on the vertical mounting groove in a sliding manner and provided with a mandrel head. The upper die is vertically and slidably mounted on the upper die plate. Elastic parts are arranged between the upper die and the upper die plate. An arc-shaped upper die cavity is formed in the lower surface of the upper die, and the upper die cavity and the lower die cavity are matched to form a die cavity for holding steel pipes. The pressing head is fixed on the upper die plate and below the upper die plate and vertically penetrates the upper die to be matched with the upper plane of the mandrel. The platform pressing mold is reasonable in structure, free of mandrel alignment, capable of quickly and correctly pressing platforms on the steel pipe surfaces, simpler to operate and higher in efficiency and yield.

Description

technical field [0001] The invention relates to a mold, in particular to a pressing platform mold for a steel pipe surface pressing platform. Background technique [0002] The surface of the steel pipe is cylindrical, and some auto parts need to stamp a concave platform on the surface of the steel pipe cylinder. However, the current method of pressing the platform is completed on a hydraulic press. The mold for pressing the platform includes an upper die and a lower die. There is a mold cavity for the steel pipe when the upper mold and the lower mold are closed. The mandrel can be put into the inner hole of the steel pipe. There is a plane on the mandrel. The specific operation is: insert the steel pipe into the Insert the mandrel into the steel pipe in the mold cavity, and manually rotate the mandrel so that the plane of the mandrel faces up and is horizontal, and then the hydraulic press controls the pressure head to press the steel pipe downward. Extrude a concave platfo...

AI Technical Summary

Problems solved by technology

The mold structure of the above-mentioned pressing platform is unreasonable, and the process is relatively complicated. It is necessary to manually insert the mandrel and the steel pipe. At the same time, the most troublesome thing is to manually find out the position of the plane on the mandrel in the steel pipe. Therefore, the process efficiency of the mold and the pressing platform low, low yield
