Overview
Numerical Control Turret Punching Machine (NCT) consists of computer control system, mechanical or hydraulic power system, servo feeding mechanism, mold library, mold selection system, peripheral programming system and so on.
Numerical control turret punch press (NCT) is through the programming software (or manually) prepared by the processing program, the servo feeding mechanism will be servo feeding the sheet to the position to be processed, at the same time by the mold selection system to select the mold library in the corresponding mold, the hydraulic power system according to the program for stamping, automatic completion of the workpiece processing.
The throat depth of CNC turret punch press (NCT) is the distance from the punching center to the side plate of the bed. The size of the throat depth directly determines the size of the width dimension of the processed plate (i.e. the size of the plate processed along the length of the bed).
Basic information of CNC turret punch pressMotion axes
X-axis: the servo-driven axis that moves the workpiece along the direction perpendicular to the length of the bed
Y-axis: the servo-driven axis that moves the workpiece along the direction parallel to the length of the bed
A-axis: the rotating axis of rotating turret-type tool magazines to select the mold
C-axis: the rotating axis of automatic indexing of the mold. The mold can be rotated at any angle
Processing Methods
1) Single Punching:Punching holes in a single pass, including straight line distribution, arc distribution, circumferential distribution, and grid hole punching.
2)Continuous punching in the same direction:Using rectangular molds partially overlapping processing can be carried out to process long holes, cut edges and so on.
3)Multi-directional continuous punching: Processing of large holes using small molds.
4)Nibbling:A processing method that uses a small round mold to continuously punch arcs in smaller steps.
5)Single-shot forming:Processing method in which a shallow deep-drawing shape is formed at one time according to the shape of the die.
6)Continuous forming: molding than the mold size of the molding process, such as large-size shutters, rolling rib, rolling steps and other processing methods.
7)Array molding: processing of multiple identical or different workpieces on a large plate processing mode.
Processing station
General thick turret molds are generally graded according to the size of the aperture molds can be processed to facilitate the selection of molds. Usually divided into A, B, C, D, E five grades.
A (1/2") station: processing range of ?1.6 ~ ?12.7mm
B (1-1/2") station: processing range of ?12.7 ~ ?31.7mm
C (2") station: processing range of ?31.7 ~ ?50.8mm
D (3-1/2") station: processing range of ?50.8 ~ ?88.9mm
C (2") station: processing range of ?31.8 ~ ?50.8mm
C (2") station: processing range of ?31.7 ~ ?50.8mm
D (2") station: processing range of ?31.8 ~ ?50.8mm
D (2") station: processing range of ?31.7~ ?50.8mm
D (2") station: processing range of ?31.8~ ?50.8~ ? 88.9mm
E(4-1/2") station: processing range:88.9~?114.3mm
Application industry
Widely used in machinery, electrical appliances, instrumentation, sieve net, hardware, all kinds of metal plates, boxes, cabinets, and other industries of stamping processing, the use of a single punching mode and step punching mode punching a variety of shapes, sizes of holes and parts, especially for multiple varieties of medium and large parts. It is especially suitable for the stamping of multi-species, small and medium-lot or single-piece plates.
Ordinary punching machine, also known as the press, is a more traditional type of mechanical processing of the stamping process. This machine tool can achieve product material and energy savings, high efficiency. The operator's technical requirements are not high, through a variety of mold applications, you can make the advantages of mechanical processing can not be achieved by the product, and therefore it is widely used. Working Principle Edit
The principle of the punch press is to convert circular motion into linear motion, from the main motor to drive the flywheel, driven by the clutch gears, crankshafts, connecting rods, etc., to reach the linear motion of the slider, from the main motor to the connecting rod of the movement of the circular motion.
The connecting rod and the slider need to have a circular motion and linear motion between the transfer point, through this mechanism will be converted from circular motion to linear motion of the slider.
The punch press is a machine that applies pressure to a material to deform it and obtain the required shape and accuracy. The reaction force caused by the force applied to the material during processing is absorbed by the punch press machine body.
Precautions for use
Before the press works
(1)Check the lubrication of each part, and make the lubrication electric power to get sufficient lubrication
(2)Check whether the molds are installed correctly and reliably;
(3)Check whether the pressure of compressed air is in the range of regulations
(4)Check whether the switch buttons are sensitive and reliable. Reliable, be sure to make the flywheel and clutch disengaged before turning on the motor;
Working
(1) should be timed with a manual lubricating oil pump to the lubrication point of the lubricating oil pressure
(2) press performance is not familiar with the press, do not adjust the press without authorization
(3) absolutely prohibit the simultaneous punching and cutting of two layers of sheet metal
(4) found that the work is not normal should be stopped immediately and the work is not normal. normal should immediately stop working and check in time.
After work
(1) Disengage the flywheel and clutch, cut off the power supply, and release the remaining air
(2) Wipe the press clean, and apply anti-rust oil to the working table surface
(3) Make a good record after each operation or maintenance.
