Hydraulic cylinder connecting rod cutting mechanism of automatic cutting machine of welded steel tube coiled material

Abstract

The invention discloses a hydraulic cylinder connecting rod cutting mechanism of an automatic cutting machine of a welded steel tube coiled material. A base plate is installed on a rack, upright posts are arranged on both sides of the base plate, a cross beam is installed on the upper ends of the upright posts, a cutting oil cylinder is installed on the cross beam, a movable cross beam connecting piece and a cutting lever piece are arranged on the cross beam, both ends of the cross beam connecting piece are respectively connected with the cross beam and one end of a connecting rod horizontal piece of a cutting die plate through pins, the middle of the cutting lever piece is installed on the cross beam through a pin, the upper and lower ends of the cutting lever piece are respectively connected with a piston rod of the cutting oil cylinder and the other end of the connecting rod horizontal piece of the cutting die plate, both ends of the connecting rod horizontal piece of the cutting die plate are connected with two connecting rod pieces of the cutting die plate through pins, the two connecting rod pieces of the cutting die plate are connected with an upper cutting die plate, an upper cutting die is installed on the upper cutting die plate, and a lower cutting die which is matched with the upper cutting die is installed on the base plate. In the mode, by using the hydraulic cylinder connecting rod cutting mechanism, steel plates of the whole coiled material can be quickly straightened and rolled, and the degree of parallelism can be corrected, and rhombic steel plates are prevented from being formed by cutting.

Description

technical field [0001] The invention relates to the field of automation, in particular to a hydraulic cylinder connecting rod cutting 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 hydraulic cylinder connecting rod cutting mechanism of an automatic cutti...
