Automatic three-line drawing machine

Abstract

The invention relates to the technical field of drawing equipment, in particular to an automatic three-line drawing machine. The automatic three-line drawing machine comprises a main rack, wherein a feeding frame is arranged on one side of the main rack; an automatic feeding mechanism is arranged on the feeding frame, a three-groove tubing device is obliquely arranged on the top layer of the main rack; a material pushing trolley is arranged at the rear end of the three-groove tubing device; an ejection pulley is arranged below the three-groove tubing device; a front material baffle is arranged at the front end of the three-groove tubing device; a tube pressing mechanism is arranged between the three-groove tubing device and the front material baffle; a core sleeving mechanism is arranged in front of the three-groove tubing device; a drawing mechanism is arranged below the main rack, and an automatic material collection mechanism is arranged on one side of the drawing mechanism. Compared with the prior art, the automatic three-line drawing machine can draw three tubes simultaneously, is compact in overall structure, occupies small floor space and is practical, efficient, automatic in the whole process, high in production efficiency and capable of effectively reducing labor intensity of an operator, the production efficiency of the automatic three-line drawing machine is more than three times higher than that an existing single-line drawing machine, and a work station is very user-friendly.

technical field [0001] The invention relates to the technical field of drawing equipment, in particular to an automatic three-wire automatic drawing machine. Background technique [0002] The hot rolling method for seamless steel pipes is the main way of producing seamless steel pipes today, but the dimensional accuracy of the steel pipes produced by the hot rolling method is not high, and even concave, straight through, indentation and other defects appear. In order to obtain a smooth surface, the dimensional accuracy is higher , the seamless steel pipe with few defects often adopts the drawing method. The drawing machine is a kind of mechanical equipment used to reduce the diameter and wall or reduce the wall and expand the diameter of the pipe.

[0002] The hot rolling method for seamless steel pipes is the main way of producing seamless steel pipes today, but the dimensional accuracy of the steel pipes produced by the hot rolling method is not high, and even concave, straight through, indentation and other defects appear. In order to obtain a smooth surface, the dimensional accuracy is higher , the seamless steel pipe with few defects often adopts the drawing method. The drawing machine is a kind of mechanical equipment used to reduce the diameter and wall or reduce the wall and expand the diameter of the pipe. At present, most of them often use chain transmission. The chain-type bar automatic drawing machine for traction and drawing needs to use manual auxiliary feeding and discharging, which cannot realize automatic production and affects the production effect. Moreover, the current drawing machines are all single-line, that is, only one wire at a time. It can draw a pipe, the production efficiency is low, and the production energy consumption is huge
