CNC Turret Punch Machine
he machine is consisted of frame, hydraulic system, worktable, turret structure, auto-index station, beam carriage, pneumatic system, lubrication system, lamp, repositioning system, electrical control system and etc.
Frame
◆Adopt the steel structure, wipe off the internal force through backfired after welding.
◆Adopt the pentahedron milling center 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 and better rigidity
Hydraulic system
◆This part is consisted of hydraulic station, 50tons punch unit and electric-card. The complete set imported from H+L Gmbh, Germany.
◆Under the control of CNC system, it can realize all kinds of punching criterion and with the hydraulic automatically overload protection.
◆The stroke of the hydraulic ram-head can be adjusted according to the actual instance, so that it can attain the better punching time.
Worktable
◆Adopts worktable with 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
◆Adopt Japan reduction box and Synchronous cog belt
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 punch , also it can be enlarge the process range for the machine.
CNC system
◆Adopt SIEMENS controller from Germany.
◆The controller can program off-line.
