Abstract

The invention discloses a square high-strength metal pipe embossing process. The embossing process comprises the following steps that 1) up-and-down rolling is carried out, specifically, the upper side surface and the lower side surface of a rectangular metal pipe are extruded and deformed through rolling by an upper wheel die and a lower wheel die, so that the outer end surfaces of the upper sideand the lower side are inwards concave; and 2) left-and-right rolling is carried out, specifically, the left side surface and the right side surface of the rectangular metal pipe are extruded and deformed through rolling by a left wheel die and a right wheel die, so that the outer end surfaces of the left side and the right side are inwards concave, wherein up-and-down rolling and left-and-rightrolling are carried out on two different stations on the same equipment, and the axes of the two stations coincide. The damage rate of stand columns produced by utilizing the process and the equipment is reduced to the current 0.7% from 8% before modification, so that the market competitiveness and the praise from customers of the product is greatly improved.

Description

technical field [0001] The invention relates to pipe beading equipment, in particular to a square high-strength metal pipe beading process. Background technique [0002] During the development, production, and use (customer) of outdoor tents, the surface of the column parts will be damaged to varying degrees, and pits and deformation will appear. The strength of the entire column is obviously not strong, which seriously affects the use of customers and has a great impact on our product sales. Therefore, we set out to change the physical structure of the metal material on the surface of the column pipe to improve the surface strength, hardness and mechanical properties of the pipe. Contents of the invention [0003] Aiming at the above-mentioned technical problems, the present invention provides a ribbing process for square high-strength metal pipes. By arranging a horizontal extrusion mechanism and a longitudinal extrusion structure at intervals in a certain linear direct...
