Feeding mechanism of automatic cutting machine for welded steel tube coil

Abstract

The invention discloses a feeding mechanism of an automatic cutting machine for a welded steel tube coil. The feeding mechanism of the automatic cutting machine for the welded steel tube coil comprises a main feeding roll shaft, U-shaped plates, a pressing roll shaft, pressing roll shaft bases, main feeding roll shaft bases, pressing oil cylinders and pulling rods. The two parallel corresponding U-shaped plates are installed on a machine frame and are connected and supported through the four pulling rods, the pressing roll shaft bases are arranged in U-shaped grooves of the two U-shaped plates and installed at the two ends of the pressing roll shaft, the upper ends of the pressing roll shaft bases are connected with piston rods of the pressing oil cylinders which are installed at the top ends of the U-shaped plates, the pressing roll shaft and the main feeding roll shaft are attached to each other in the same direction, the two ends of the main feeding roll shaft are provided with the main feeding roll shaft bases, and the main feeding roll shaft bases are installed on the U-shaped plates through screws. In this way, a whole coiled steel plate can be rapidly straightened and rolled to be flat, the depth of parallelism is modified, and no diamond-shaped steel plates are obtained through cutting.

Description

technical field [0001] The invention relates to the field of automation, in particular to a feeding mechanism of an automatic cutting machine for welded steel pipe coils. Background technique [0002] Some thin-walled straight seam welded steel pipes are widely used, including power line laying, ventilation, drainage, hot steam, etc. Different industries have different requirements for welded pipes, and straight seam welded steel pipes are integral Rolled steel plates are produced, but before welding, the whole roll of steel plates must be straightened and cut. The existing process uses a relatively simple roller-type leveling mechanism, and the effect is poor. , and accurate fixed-length cutting cannot be performed, and beveled edges will also appear. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a feeding mechanism of an automatic cutting machine for welded steel pipe coils, which can quickly straighten...
