Vertical frame forming structure of stainless steel tube making machine

Abstract

The invention discloses a vertical frame forming structure of a stainless steel tube making machine. The vertical frame forming structure comprises a rack, a horizontal roller assembly and two side roller assemblies, wherein the horizontal roller assembly comprises a lifting adjusting drive mechanism, an upper horizontal roller piece and a lower horizontal roller piece, wherein the lifting adjusting drive mechanism is used for driving the upper horizontal roller piece to move in the vertical direction; the two side roller assemblies are arranged between the upper horizontal roller piece and the lower horizontal roller piece in a bilateral symmetry mode, each side roller assembly comprises a vertical die roller, a mounting base, a horizontal movement adjusting drive mechanism and a lockingmechanism, the horizontal movement adjusting drive mechanism being used for enabling the vertical die rollers to horizontally move in the left-right direction. According to the technology, a pipe blank can be extruded in four directions at the same time, so that forming force vertically acts on the pipe blank, and pulling damages and friction of a steel belt to a pipe are reduced; a relative distance between the upper horizontal roller piece and the lower horizontal roller piece can be adjusted according to formed pipes with different outer diameters, relative positions between the two vertical die rollers and the lower horizontal roller piece are adjusted, and the relative distance between the two vertical die rollers is adjusted.

Description

technical field [0001] The invention relates to the technical field of stainless steel pipe production equipment, in particular to a stand forming structure of a stainless steel pipe making machine. Background technique [0002] Stainless steel pipes are widely used in many fields such as electric power, machinery, construction, home decoration, etc. due to their light weight, strong structure and good mechanical performance. Due to the different requirements for the size and wall thickness of stainless steel pipe fittings in different applications, so in the production of stainless steel pipes In the process, there are more and more requirements on the specification, size, structure and mold roll specification of the stainless steel pipe making machine. At present, the stainless steel pipe making machine has the following defects and deficiencies in the production process: the forming structure in the existing stainless steel pipe making machine cannot be used universally w...

AI Technical Summary

Problems solved by technology

At present, the stainless steel pipe making machine has the following defects and deficiencies in the production process: the forming structure in the existing stainless steel pipe making machine cannot be used universally when producing pipes of different specifications, and the specifications of the forming structure need to be changed frequently, resulting in high labor costs and low production capacity. Bottom, high scrap rate, unreasonable forming force direction, sizing pressure direction and mold roller force, large forming resistance, resulting in serious strain and wear of the mold roller, large deformation of parts, fast damage, short service life, maintenance High cost and low automation
