Technical Field

The invention relates to the technical field of stainless steel pipe production, in particular to an automatic pipe sawing device and method for a stainless steel pipe.

Background

At present, more and more stainless steel tube production enterprises in the industry combine the original relatively independent tube cutting equipment with the front and back procedures, and the production efficiency is greatly improved. The steel pipe is conveyed to a feeding and storing area through the last working procedure, after the fixed-size tool fixture is manually checked and installed, the steel pipe is automatically fed onto a conveying roller way, and then the conveying roller way conveys the steel pipe to a roller way to be cut; when one end of the steel pipe reaches the positioning end, an operator issues a cutting instruction, and the pipe sawing machine performs cutting work on the steel pipe; after cutting, the steel pipe is automatically discharged into the material storage device by the automatic discharging device; and the operator then hoists the steel pipe in the material storage device to other areas to carry out deburring work on the end part of the steel pipe.

However, in the actual use process, a number of problems have been found to exist. Such as:

(1) and after the last working procedure is finished, the steel pipe is conveyed to a feeding section. For the steel pipe to be transferred to a feeding section conveying roller way from a feeding section, most of the prior pipe sawing equipment adopts automatic feeding. However, the automatic feeding speed is too high, so that the steel pipes and the roller way are obviously collided, and the surface quality and the product performance are influenced;

(2) at present, most pipe sawing equipment in the market needs to lift up and lift off the steel pipe after finishing the sizing and cutting of the steel pipe. In order to meet the requirements, most equipment manufacturers adopt a cylinder jacking force mode, but due to the characteristics of the cylinder jacking force, the steel pipe obviously shakes and collides in the jacking and lifting processes;

(3) frequent manual intervention is needed to intervene in the positioning work of steel pipes with different lengths, and the manual positioning has the problems of poor positioning precision and low working efficiency;

(4) after the steel pipe is conveyed to a positioning tool with a specified size, whether the steel pipe is in place or not is judged mainly by means of naked eye identification of personnel. If the steel pipe is identified in place early, the length of the cut steel pipe is insufficient; the steel pipe slides on a conveying roller way due to too late recognition, and the surface of the steel pipe is scratched to different degrees, so that the appearance and the performance of a product are influenced;

(5) after the steel pipe is positioned in a fixed size, an operator manually operates the steel pipe to start the pipe sawing machine to cut. The existence of the time interval greatly reduces the production efficiency under the condition of large-batch and long-time accumulation;

(6) and after the steel pipe is cut in a fixed size, directly entering a material storage process of the steel pipe. The work of removing burrs at the cut end part of the steel pipe becomes a difficult problem, and the steel pipe at the material storage section is often required to be transferred to other places and then deburred; the method not only occupies additional field, but also greatly reduces the working efficiency;

(7) because the steel pipe is from "jacking" and "lifting off" to "stock section", will lead to the steel pipe with certain height and angle, roll and fall to "stock section", will increase the dynamics of colliding with between steel pipe and the steel pipe, form the relatively serious bruise of degree.
