High speed CNC H beam Drilling Machine Core equipment of Steel Structure
Application industry:
This machine tool is mainly used for drilling of H-shaped steel. The machine tool uses three high-speed precision drilling spindles to drill the workpiece. It has the characteristics of high machining accuracy and convenient operation. It is an indispensable high-efficiency equipment in the steel structure industry and is widely used in construction, bridges, tower masts and grids. And other industries.
Machine structure:
1．This machine tool is mainly composed of main machine body, cnc feeding system, material conveyor, electrical system, hydraulic system, cooling system, lubrication system, waste box and other parts. The machine tool adopts a fixed bed structure and a movable workpiece structure, which is suitable for the processing of large H-shaped steel, is convenient for continuous production, and has a high degree of automation.
2．The drilling machine body is composed of bed, CNC sliding table components, supporting device, upper pressing device, side pressing device, detection device and so on. The parts of the numerical control sliding table are the fixed side, the moving side and the upper unit numerical control sliding table. The sliding table components are composed of a sliding plate, a sliding table seat, a headstock, a high-speed mechanical spindle, a tool cylinder, a frequency conversion motor, a servo motor, a linear guide, a lead screw, etc., which are used for drilling of H-shaped steel.
3．The CNC feeding system is composed of bracket, gear, rack, servo motor, reducer and manipulator. The servo motor drives the manipulator to drive the H-shaped steel to move in the X direction to feed the H-shaped steel, which can realize the precise positioning of the workpiece.
4. The material conveyor is divided into a material feeding conveyor and out-feeding conveyor. The feeding conveyor is composed of a conveyor support, a supporting roller, a side pushing device, etc., which is used to carry the profiled steel blank, position the profiled steel blank in the Y direction and cooperate with the CNC feeding device to feed. The out-feeding conveyor is composed of a material channel bracket, a supporting roller, etc., which are used to carry the finished workpiece.
