One. Machine main technical parameter

Main Features:

Designed by Nisshinbo, Japan. Nisshinbo supply the key components, it is the new generation of CNC turret punch.

Frame

-  Adopt the steel structure, wipe off the internal force through backfired after welding.

- Adopt the pentahedron milling centre which imported from Spain, finished all machining surfaces after one time setting up. Ensure the high precision and high quality of machine.

- Adopt the closed “O” type, more stable.

Servo punch system

- The parts are adopted 30T punch units and electric cards,from LUSTSP,Germany

- Can make many puch and shear work under CNC controller

- The punch head can reach much better puch times according to the adjustment of servo punch head stroke

Worktable

- Adopts brush worktable with some ball steel.

Turret structure

- Thick turret structure, imported with original packaging from Nisshinbo, Japan, ensures the accuracy and wearing capacity of the turret.

- Slow down and drive system imported from Japan.

Auto-index station

- Adopts keeping touch index tool position worm wheel

driven unit , ensure the bidirectional driven precision.

- In order to ensure high precision and reliability,

worm wheel units Are imported from Japan with original

packaging.

Beam carriage & clamps

- Adopts the high precision, long-stroke ball screw and linear guideway, having rapid speed, high moving precision, and long life.

- High strength prolonged clamp makes the dead zone of clamp as smaller as possible.

- Each clamp has one sensor, once sheet is loosened, punching operation will stop immediately.

Pneumatic system and lubrication system

- Consists of air-source treatment 4-unit and every control air-valve, and the pressure is 0.65Mpa, the perform components have turret position cylinder, X axes origin position cylinder, re-position cylinder and clamp etc.

- Adopts centralized lubricate mode.

Repositioning

-  The repositioning is consisted of two cylinders and relevant valves. When the machine is in repositioning, it tightly press the workpiece press on the worktable, and when the clamp moves, the workpiece cannot move, to ensure the precision of the position of the two punching , also it can be enlarge the process range for the machine.

CNC system

- Adopts the SIEMENS controller from Germany.

Two. Machine content description
1.  Control system: Adopt Spain Fagor/Siemens cnc system, semi-closed loop control, cooperate with Estun numerical control punch servo module, which can realize four axis control at the same time, Equipped with USB, R232 communication interface which can realize the front desk, backstage programming.
Software:Adopts CNCKAD software can realize AutoCAD graphics automatically converts processing procedure, bring their own mould library management, automatic optimization of processing path, realize plank material automatic relocation, plate automatic relocation, no dead zone for processing; The operation is simple, and can realize one-click operation;
2.  Stamping subject:Fuselage is O type Steel welding, the whole pass by tempering treatment, make sure the equipment good appearance and long-term stability;
3.  Turret Organization:Adopt high strength nodular cast iron to cast into integral thick turret mould plate, thickness is 80mm, through heat treatment to get rid of internal stress, rigid good, precision stability, impact resistant ability good; greatly improving mould service life;
4.  Mould: adopts AMADA standard thick turret mould, convenient for daily maintenance and procurement;
5.  Motor/drive: Aston high-power servo motor and servo drive system, speed 3000 r/min, high feeding speed, high precision;
6.  Transport Ball Screws: Germany Ball Screws, attainability 5 grade precision;
7.  Guide Rail: Taiwan Linear Guide, With Wider Flange-type Slider to ensure the equipment operating more stability;
8.  Orientation Cylinder:Import Korea brand cylinder to achieve precise positioning of the purpose of locking;
9.  Reducer: Precision turbine worm reducer, with band-type brake function, reduce the impact to the servo motor after the mold high-speed operating, at the same time guarantee the turret high-speed positioning accuracy;
10.  Clamp:Adopt float type pneumatic clamp, can be together with plates float, avoid plates distortion;
11.  Working table:High quality brush steel ball mixed countertops, greatly reduces the friction plate movement, effective protection plate surface;
12.  Lubricating system:Adopt the automatic control system of oil station, according to the preset time, guide rail, screw etc main transmission mechanism can realize automatic centralized lubrication;
13.  Main electrical components:relays, photoelectric sensors, contactor, etc all adopt the Omron and Schneider brand, long-term guarantee the safety of the device;
14．Rotating station: Adopt the standard structure of worm and worm wheel rotating mechanism, the whole mechanism is processed by high precision grinding processing equipment, fully guarantee the centring of upper and lower mould after long-term rotation of rotating station, increase the service life of mould, effectively solve the difficulty of arbitrary Angle punching and trimming;
15.  Stamping main servo system: Adopting ESTON high-power servo motor, punch frequency up to 1900 times, punch force stable, using water cooling, the stability is higher.
