Feed type 3D NC drilling machine can be widely used in buildings, bridges, power plant boiler, three-dimensional garage, marine oil drilling platform, tower masts and other steel structure industry to send SWZ1250 roller, especially suitable for H type steel structure steel, channel steel, has the characteristics of high precision, convenient operation etc..
The structure characteristics of the machine tool:
1, SWZ1250 roller feeding type 3D NC drilling machine is mainly composed of a bed body, digital control slipway, self controlled stroke drilling several power head, clamping mechanism, detection device, cooling system, iron box, safety nets and other major parts.
2, the bed is the frame type structure is composed of high quality steel welded together, and in place of the square steel tube by the greater force was strengthening treatment by finite element analysis, the welding was performed after thermal ageing treatment, these are very good to improve the static and dynamic performance of lathe bed, so as to ensure the accuracy of the entire lathe.
3 digital control slipway, a total of 3, are fixed side NC slide, moving side digital control slipway and the middle unit of numerical control slide, three slide structure is the same, all by the apron, slider and servo drive system composed of. Three slipways had a total of 6 NC axes, each slide has 2 NC axes, each axis of CNC are used precision linear rolling guide rail, driven by AC servo motor + ball screw. Thus, each slide can move in two directions, both along and perpendicular to the direction of the workpiece to NC movable, and can be sent to the direction of movement along the workpiece nc. A feeding, in the same position, to complete the H type steel the last hole group (range 520mm) the processing of all holes, to ensure the workpiece not in the same section hole also can be processed simultaneously, greatly improving the positioning accuracy and efficiency of the Kong Qun inner hole.
Boring power head 4, three self controlled stroke drilling, are respectively arranged on the three NC slide slip board, drilling of the horizontal direction and the vertical direction, three drilling power head can work alone can work at the same time. Boring power head self controlled stroke the machine used to drill, without the need for manual setting bit length and thickness of the workpiece, the conversion will be able to automatic fast forward - feeding - rewind.
5, the workpiece is fixed by hydraulic clamping mechanism on the workpiece in the horizontal direction and the vertical direction is fixed on the clamping.
6, the machine is equipped with a workpiece width detection and web height detection device, automatic compensation for machining error of workpiece outline irregular brings, improve processing accuracy.
Equipped with spray cooling system 7, machine tool, the utility model has the advantages of less amount of coolant is, save the cost, reduce the wear of drill.
8, the machine is equipped with iron box, chips can be automatically discharged into the box, very convenient transportation.
9, in order to ensure the safety of the operator and the surrounding environment, the machine is provided with a safety net around.
10, SWZ1250 roller feeding type 3D NC drilling machine electric control system using PLC programmable controller, motion control module, input / output module, high-speed counter module to control the core, with the host computer, AC servo drive system, frequency conversion system composition, system operation has 7 CNC servo motor shaft.
11, to ensure that the machine precision and reliability of key parts of the production line, such as: ball screw, cooling parts, hydraulic valve, servo driver and servo motor, PLC, transducer, encoder, towline, adopt international famous brand.
