Large-diameter steel strip winding pipe die and winding method thereof

Abstract

The invention discloses a large-diameter steel strip winding pipe die and a winding method of the large-diameter steel strip winding pipe die. A first supporting disc is arranged on a unit spindle, aplurality of gear discs are arranged on the first supporting disc, rollers are installed on the gear discs, and rolling shafts are installed in the rollers. The tail ends of the rollers are installedon a second supporting disc, and the two ends of each roller are connected with the two gear discs arranged on the corresponding rolling shaft correspondingly. A mandrel is arranged in the middle of the first supporting disc and the middle of the second supporting disc in a penetrating mode, a pin hole is formed in the end, penetrating out of the second supporting disc, of the mandrel, and a hingepin is inserted into the pin hole. The winding method comprises the steps that sampling is conducted through a high-frequency data acquisition card; the step length voltage value is calculated; the step length voltage value is converted into pressure data, and detection information is sent; the speed of a motor is adjusted according to the detection information, and a hydraulic rod is adjusted tocontrol the appearance structure of the die at the same time. By the adoption of the large-diameter steel strip winding pipe die and the winding method, the forming quality of pipelines is improved,the formed pipelines are closely attached to the surface of the die and easily fall off, the production efficiency and the product quality are improved, and the large-diameter steel strip winding pipedie and the winding method can be used for producing straight pipes and taper pipes.

Description

technical field [0001] The invention belongs to the technical field of pipe production molds, in particular to a large-caliber steel strip winding pipe mold and a winding method thereof. Background technique [0002] Steel belt winding pipe has the advantages of corrosion resistance, light weight, easy installation, large flow rate and long life, and is an environmentally friendly green product. It has gradually replaced pipes made of high energy consumption materials such as cement, cast iron, and ceramics. [0003] At present, in the process of producing large-diameter steel belt winding pipes, the steel belt winding pipe mold must be fixed on the main shaft of the unit. The mold rotates with the main shaft, and the steel belt rotates with it and is wound on the mold, and finally formed. Existing steel strip winding molds often adopt integral cylindrical structure. When using this mold to produce large-diameter pipes, it is easy to cause the formed pipes to adhere to the s...

Problems solved by technology

[0004] The purpose of the present invention is to provide a large-diameter steel strip winding pipe mold and its winding method, aiming at solving the problem that the formed pipe is tightly attached to the surface of the mold and is not easy to fall off, which affects production efficiency and product quality, and the mold can only be used directly. The production of tubes, but cannot be applied to the production of tapered tubes
