CNC punch sheet metal processing technology, how much do you know?

CNC punch sheet metal processing stamping is an important link in sheet metal processing, CNC punch can replace the past three punch processing capacity. Productivity has been greatly improved.

CNC punch is a widely used machine tool, there are two kinds of single punch and turret. CNC turret punch (NCT) machine, electric, liquid, gas integration, is in the plate punching processing, shallow deep drawing molding pressure processing equipment.

A, CNC punch processing methods

1, single punching: a single time to complete punching, including circular distribution, circular distribution, linear distribution, grid hole distribution.

2, multi-direction continuous blanking: the use of small mold processing big hole processing.

3, single molding: according to the mold shape of a shallow deep drawing molding processing mode.

4, the same direction of continuous blanking: the use of rectangular mold overlaps processing mode, can be processed edge cutting, long holes, etc..

5, nibbling: the use of small round die with a small step for continuous punching array arc processing.

6, array forming: processing a number of different or the same workpiece processing on the large plate.

7, continuous forming: forming larger than the mold size of the molding process, such as rolling steps, rolling ribs, large size shutters and other processing methods.

Two, CNC punch processing technology characteristics


1, easy to use. Save the cost of opening the mold, CNC turret punch (NCT) is a machine, electric, liquid, gas in one of the pressure processing equipment, used for all kinds of metal sheet parts processing, can be in the plate for a variety of complex hole processing, shallow deep drawing molding processing, can be a one-time automatic parts processing.

CNC turret punch press is one of the most vital pressure processing equipment. CNC punching machine not only can automatic processing according to the requirements of different size and pitch of the different shape of hole, also can use small die in step blunt blunt big round hole, square hole, waist type hole and various shapes of curve contour, also can undertake special craft processing, such as blinds, shallow drawing, sink hole, hole flanging, reinforcement, stamping, etc. Compared with the traditional stamping, CNC punch saves a lot of mold costs, can use low cost and short cycle processing of small batch, diversified products, with a larger processing range and processing capacity, so as to timely adapt to the market and product demand changes.

2, high processing accuracy, with stable processing quality CNC punch cutting precision, small punching burr, good smoothness of the workpiece, less subsequent processing, low reject rate, high forming quality, number of processing size accuracy can reach 0.1mm, product size consistency is good.

3, the machine can process the workpiece individually or batch process the workpiece with group command, improve productivity. CNC punch processing speed, general hydraulic equipment stroke rate can reach 500 ~ 600 min, some even up to 900 min, the maximum positioning speed can reach more than 100mmin. For large size plate can be basically up to a processing can be completed, unlike the traditional processing, need multiple processes, in many different equipment processing.

4, processing parts change, generally only need to change the NUMERICAL control program, can save production preparation time.

5. Higher requirements for the quality of operators and higher technical requirements for maintenance personnel.


Three, the development trend of CNC punch technology

The application of NUMERICAL control technology not only brings revolutionary changes to the traditional manufacturing industry, so that the manufacturing industry has become a symbol of industrialization, at present, the world's numerical control technology and equipment development trend mainly has the following aspects.

1, high speed, high precision processing technology and equipment of the new trend efficiency, quality is the main body of advanced manufacturing technology.

2, 5 axis linkage processing and compound processing machine tool rapid development.

3, intelligent, open, network has become the main trend of the development of contemporary CNC system.

4. Attach importance to the establishment of new technical standards and norms.
