Numerical control flexible roll bending plate bending machine for small-diameter thin-walled pipe body

Abstract

The invention discloses a numerical control flexible roll bending plate bending machine for a small-diameter thin-walled pipe body, and relates to the technical field of plate bending machines. A lower rubber-covered roller (6) is arranged on a rack (1), wherein a rotating shaft of the lower rubber-covered roller (6) is connected with a transmission device (2); a displacement sensor (5) is arranged between the lower rubber-covered roller (6) and an upper rubber-covered roller (7); piston rods of two oil cylinders (4) are connected with the two ends of the lower rubber-covered roller (6) respectively; a hydraulic station (3) is arranged at the lower end of the rack (1); a PLC (programmable logic controller) control cabinet (10) is arranged on one side of the hydraulic station (3); a die roller (8) is arranged on the upper side of the lower rubber-covered roller (6); the upper rubber-covered roller (7) is arranged on the upper side of the die roller (8); a die following constraint device (9) is arranged at one end of the die roller (8); a return device is arranged on the lateral surface of the rack (1). According to the plate bending machine, a flexible roll bending forming mode is adopted, so that the surface of a workpiece is difficult to scratch, the automation degree is improved, the production cost is lowered, the production efficiency is improved, the safety is improved, and the roundness and the cylindricity of formed workpieces are favorably ensured.

Description

Technical field: [0001] The invention relates to the technical field of plate rolling machines, in particular to a small-diameter and thin-walled pipe body flexible rolling numerical control plate rolling machine. Background technique: [0002] With the rapid development of automobile manufacturing, aerospace industry, chemical metallurgy and other fields, small-diameter and thin-walled pipe bodies of various new materials and alloy materials have been widely used as parts. [0003] Small-diameter thin-walled pipes refer to the thickness of the plate being 0.2-5mm, the plate width greater than 500mm, and the diameter in the range of 20-100mm, while the conventional plate rolling machine cannot achieve rolling. [0004] There are few finished products on the market for this type of pipe material, and even if it is supplied, it may not necessarily meet the user's size requirements, and the price is relatively high. Summary of the invention: [0005] The purpose of the present invention...
