[0003] However, if this type of hacksaw machine adopts the sawing method of sawing profiled steel to cut angle steel, the starting point of the saw blade for sawing angle steel falls on the front of the leg of the angle steel, and the initial resistance of the saw blade cutting into the angle steel is large. The saw blade is not allowed to cut into the angle steel. In this way, not only the sawing time of the saw machine will be prolonged, but also the section of the angle steel after sawing will have sawing burrs that exceed the standard. figure 2 As shown, it can be seen that the sawing method used by the steel saw machine cannot meet the sawing requirements of the angle steel.

The invention discloses a control method for sawing angle steel of a hacksaw machine, which includes the following functional modules for controlling the above-mentioned mechanical operation: a manual translation control unit for the rocker arm of the saw machine, a manual lifting control unit for the rocker arm of the saw machine; The vertical sawing speed selection unit; the horizontal sawing position setting unit of the rocker arm of the saw machine; the automatic interruption of the saw machine back to the waiting position operation control unit; the automatic sawing control unit of the saw machine; When it reaches the position of 50 mm away from the angle steel, in order to prevent the saw blade from hitting the angle steel at high speed, the lowering speed of the rocker arm is required to be quickly switched to the set sawing speed, and a variety of control methods are set to effectively saw the H-beam and angle steel. , to increase the processing speed.
Description
technical field [0001] The invention relates to a control method of a hacksaw machine, in particular to a control method for sawing angle steel of a hacksaw machine. Background technique [0002] The saw machine is mainly composed of the saw machine rocker arm hydraulic (translation) feed mechanism (referred to as the saw machine rocker arm feed mechanism), the saw machine rocker arm hydraulic lifting mechanism (referred to as the saw machine rocker arm lift mechanism), the main drive motor, and the main drive deceleration mechanism. It is composed of machine thin oil lubrication system, and its mechanical structure diagram is as follows figure 1 As shown, the rocker arm lifting mechanism of the saw machine is mainly composed of the rocker arm body, the rocker arm lifting swing bracket, the rocker arm lifting swing hydraulic cylinder installed at one end of the rocker arm, and the main drive reducer and saw blade installed at the other end of the rocker arm. composition. W...
