Rolling mill for rolling tooth marks on surface of metal belt

Abstract

A rolling mill for rolling tooth marks on the surface of a metal belt comprises a machine body, a second roller rotationally arranged on the machine body, a first bearing block arranged on the machinebody in a sliding manner and a die roller rotationally arranged on the first bearing block and used for installing a die. The axis line of the die roller is parallel to the axis line of the second roller. The sliding direction of the first bearing block is the direction where the axis line of the die roller is close to the axis line of the second roller. A first inclined block is fixedly arrangedon the first bearing block, the machine body is provided with a second inclined block in a sliding manner, the sliding direction of the second inclined block is perpendicular to the sliding directionof the first bearing block, and the contact face of the first inclined block and the second inclined block is an inclined face parallel to the axis line of the die roller. The extension direction ofthe inclined face and the sliding direction of the first bearing block are in intersection and form an acute angle. The inclined face serves as the displacement conduction face, and the roller gap between the die roller and the second roller is accurately controlled.

Description

technical field [0001] The invention relates to a special machine for rolling tooth marks on the surface of a metal strip. Background technique [0002] In the processing of internally threaded pipes and high-efficiency pipes, when the raw material is copper, the ball spinning method is often used for production. When the raw material is titanium or stainless steel and other metals with high hardness, the ball spinning method is inefficient. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] Existing tooth mark pressing machines mostly use the metal belt to pass through the roll gap between the mold roll and the power roll, and the pressure is provided by manually rotating the screw to reduce the roll gap until the mold roll presses the tooth marks on the surface of the metal belt. The raw material is titanium or stainless steel. When other metals with high hardness are use...

AI Technical Summary

Problems solved by technology

[0004] Existing tooth mark pressing machines mostly use the metal belt to pass through the roll gap between the mold roll and the power roll, and the pressure is provided by manually rotating the screw to reduce the roll gap until the mold roll presses the tooth marks on the surface of the metal belt. The raw material is titanium or stainless steel. For metals with high hardness, the pressure provided by the manual rotating screw is too small and the stability is poor, so that the consistency of the rolled tooth marks is poor and cannot meet the design requirements
