Abstract

The invention discloses a downward pressing structure special for a building steel bar cutter. The downward pressing structure comprises a supporting column, an ejector rod, a fixing plate, a protecting piece, a hydraulic cylinder, a pressing plate, a guide rod and a lubricating device; the lubricating device is installed at the top of the ejector rod, an oil bin is installed inside the lubricating device and can store lubricating oil, the lubricating oil is discharged through a branch pipe at the bottom and then enters a fixing sleeve through an oil pipe, namely, the position of the guide rodcan be lubricated, the effect is good, and the lubricating efficiency is high. A reciprocating mechanism is installed in the lubricating device and controlled by an independent driving motor, so thata fixing plug at the bottom is moved out of a bottom outlet of the oil bin, the lubricating oil can stably flow into the branch pipe at the bottom, excessive manual operation is not needed, and the automation effect is good; the oil absorption cotton is installed in the fixing sleeve and absorbs the lubricating oil discharged from the oil pipe, and then the lubricating oil seeps out through a permeation ring on the inner side of the fixing sleeve, so that the contact position of the guide rod and the fixing plate is continuously and stably lubricated.

Description

technical field [0001] The invention relates to the relevant field of steel bar cutting machine accessories, in particular to a special pressing structure for a building steel bar cutting machine. Background technique [0002] Construction steel bars refer to various steel bars, steel wires and other steel bars used in reinforced concrete. According to the steel types, they are divided into: non-alloy steel bars, low-alloy steel bars, and alloy steel bars; when building bars are used, special cutting machines are required. It cuts. The steel bar cutting machine is a tool used to cut steel bars. There are fully automatic steel bar cutting machines and semi-automatic steel bar cutting machines. On the automatic cutting machine, a special pressing structure needs to be installed to make the knife head Press down to cut off the steel bar. [0003] In the actual use of the special pressing structure of the construction steel bar cutting machine, guide rods are installed at both ...
