Problems solved by technology

Mechanical surface treatment is a strengthening method that introduces plastic deformation on the metal surface, even produces work hardening, and generates residual compressive stress. At present, in the traditional mechanical surface strengthening treatment such as surface shot peening, laser surface impact and other technologies, the equipment is usually complicated and bulky , requires a large operating space, and it is difficult to achieve mechanical surface strengthening treatment on the inner wall of metal pipes, etc., and cannot effectively improve the corrosion resistance of the inner wall of metal pipes

Embodiment Construction

[0031] The present invention is described in further detail below in conjunction with accompanying drawing:

[0032] Such as Figure 1 to Figure 4 As shown, a metal pipe inner wall surface rolling processing device of the present invention includes a rolling wheel 1, a connecting shaft 2 and an indenter 3, the rolling wheel 1 is a cone, the connecting shaft 2 and the indenter 3 are fixedly connected, and the connecting shaft Between 2 and the indenter 3, a plurality of rolling wheels 1 are evenly arranged along the axis of the connecting shaft 2. The axis of the rolling wheel 1 is parallel to the axis of the connecting shaft 2. The rolling wheel 1 can rotate along its own axis, and the connecting shaft 2 can drive the rolling wheel 1 to rotate along the axis of the connecting shaft 2, and at the same time, the rolling wheel 1 rotates along its own axis. Such as Image 6 As shown, the rolling wheel 1 is installed between the pressing head 3 and the connecting shaft 2 through ...

Abstract

The invention discloses a metal pipe material inner wall surface rolling processing device and method. Rolling wheels, a connecting shaft and a pressing head are adopted to form a rolling structure which can rotate and revolve, the rolling wheels are cones, one end of the connecting shaft is fixedly connected with one end of the pressing head, and the multiple rolling wheels are uniformly arrangedbetween the connecting shaft and the pressing head along the axial circumference of the connecting shaft. The inner surfaces of metal pipe materials to be processed can be gradually expanded and supported by using the surfaces of the cone-structural rolling wheels, meanwhile, the connecting shaft and the pressing head are used as rotation brackets of the rolling wheels, in the process of axial feeding of the rolling wheels, the rolling wheels can rotate and roll at the same time, and the problem of scratching caused by sliding friction of the rolling wheels and the inner surfaces of the pipematerials is solved. The conical rolling wheels are adopted, sequential rolling can be achieved, the large expansion and supporting of the surfaces of the inner walls of the metal pipe materials are avoided, the structure is simple, the mechanical surfaces of narrow workpieces such as the inner walls of the metal pipe materials can be processed, the processing efficiency of the materials is effectively improved, the product using performance is improved, and the production energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of processing the inner wall surface of metal pipes, and in particular relates to a rolling processing device and method for the inner wall surface of metal pipes. Background technique [0002] Under the action of corrosive media and loads, most of the corrosion and other failures of metal pipes such as oil pipes start from the inner wall, which is very sensitive to the structure and surface properties of the material surface. Surface engineering technology is a surface strengthening treatment process that is widely used to solve such problems. Mechanical surface treatment is a strengthening method that introduces plastic deformation on the metal surface, even produces work hardening, and generates residual compressive stress. At present, in the traditional mechanical surface strengthening treatment such as surface shot peening, laser surface impact and other technologies, the equipment is usually complicate...
