What equipment is turret punch? Is it the same as a common punch?

Numerical control turret punch (NCT) is a kind of pressure processing equipment integrating machine, electricity, liquid and gas, which is used for punching and shallow drawing of sheet metal. This is not the same as an ordinary punch.

abstract

CNC turret punch is composed of computer control system, mechanical or hydraulic power system, servo feeding mechanism, die base library, die selection system and peripheral programming system.

NC turret punch (NCT) is a processing program compiled by programming software (or manual). The servo feeding mechanism sends the sheet to the position to be processed, and at the same time, the mold selection system selects the corresponding mold in the mold library, and the hydraulic power system carries out stamping according to the program to automatically complete the processing of the workpiece.

The throat depth (NCT) of CNC turret punch is the distance from the center of the punch to the side plate of the lathe bed. The throat depth directly determines the width and size of the processed plate (that is, the size of the plate processed along the length of the bed).

Basic information motion axis of CNC turret punch

X-axis: the servo drive shaft that moves the workpiece along the direction perpendicular to the length of the lathe bed.

Y-axis: the servo drive shaft that moves the workpiece along the direction parallel to the length of the lathe bed.

Axis A: Rotating turret tool magazine selects the rotating axis of the die.

C-axis: the rotating axis of automatic indexing of the mold, which can rotate the mold at any angle.

job operation

1) Dan Chong: Punching can be completed at one time, including straight hole arrangement, circular hole arrangement, circumferential hole arrangement and grid hole punching.

2) Continuous blanking in the same direction: Long holes and trimming can be processed by partially overlapping rectangular dies.

3) Multi-directional continuous blanking: the processing method of processing large holes with small dies.

4) Step punching: continuous punching into an arc with a small circular die in small steps.

5) One-step molding: one-step shallow drawing molding according to the mold shape.

6) Continuous molding: molding processing methods larger than the mold size, such as large-size shutters, rib rolling, step rolling and other processing methods.

7) array forming: machining a plurality of identical or different workpieces on a large plate.

Processing station

Generally, the thick turret dies are generally classified according to the size of the aperture that the dies can process, which is convenient for the selection of dies. It is usually divided into five grades: A, B, C, D and E. ..

A( 1/2 ") station: processing range? 1.6~? 12.7 mm

B( 1- 1/2 ") station: processing range? 12.7~? 3 1.7 mm

C(2 ") Location: Processing range? 3 1.7~? 50.8 mm

D(3- 1/2 ") station: processing range? 50.8~? 88.9 mm

E(4- 1/2 ") station: processing range? 88.9~? 114.3mm

Application industry

Widely used in machinery, electrical appliances, instruments, screens, hardware, various metal plates, boxes, cabinets and other industries stamping process. It uses single stamping and step-by-step stamping to punch holes and parts of various shapes and sizes, and is especially suitable for stamping various small and medium-sized batches or single-piece plates.

Ordinary punch, also known as press, is a traditional mechanical processing method of stamping process. The machine tool can achieve the effects of saving product materials and energy and high efficiency. The technical requirements for operators are not high. Through the application of various molds, we can make product advantages that mechanical processing can not achieve, so it is widely used. Working principle editing

The principle of punching machine is to convert circular motion into linear motion, and the flywheel is driven by the main motor, and the gear, crankshaft and connecting rod are driven by the clutch to realize the linear motion of the slider. The motion from the main motor to the connecting rod is circular.

There is a connection point between the connecting rod and the slider between circular motion and linear motion, and the circular motion is transformed into linear motion of the slider through this mechanism.

Punch presses the material through the machine to deform it, so as to obtain the required shape and accuracy. The reaction force caused by the force applied to the material during machining is absorbed by the main body of the punching machine.

Precautions for use

Before the puncher works.

(1) Check the lubrication of all parts to fully lubricate the lubricating electricity.

(2) Check whether the mold installation is correct and reliable;

(3) Check whether the compressed air pressure is within the specified range.

(4) Check whether the switch button is sensitive and reliable, and ensure that the flywheel and clutch are disengaged before starting the motor;

at work

(1) Use a manual lubricating oil pump to regularly deliver lubricating oil to the lubricating point.

(2) When you are not familiar with the performance of the press, you are not allowed to adjust the press without authorization.

(3) It is absolutely forbidden to punch two layers of metal plates at the same time.

(4) Stop working immediately when finding abnormal work, and check it in time.

after work

(1) Disconnect the flywheel and clutch, cut off the power supply and release the remaining air.

(2) Wipe the press clean and coat the workbench with antirust oil.

(3) Make records after each operation or maintenance.
