With the gradual popularization and popularity of numerical control in machine tool industry, numerical control punch is the hot key word of punch in August.
CNC punching machine can be used to process all kinds of sheet metal parts. It can automatically complete a variety of complex hole patterns and shallow drawing forming processes at one time. (according to the requirements, it can automatically process holes with different sizes and different shapes of hole spacing. It can also punch large round holes, square holes, waist shaped holes and curve profiles of various shapes by step punching with a small die. It can also be used for special processing, such as blinds, louvers, etc Shallow drawing, counterbore, flanging hole, stiffener, embossing, etc.). Compared with the traditional stamping, the simple die combination can save a lot of mold costs. It can process small batch and diversified products with low cost and short cycle. It has a large processing range and processing capacity, so as to adapt to the market and product changes in time.
At the same time, Jiangsu Yawei and Jinfangyuan, Amada, tailifu and Qingdao Dadong technology, which produce CNC punching machines, have become the focus of CNC punch enterprises in August.
At present, many turret presses have adopted numerical control system. CNC turret punch press (NCT) is a processing program compiled by programming software (or manual). The servo feeding mechanism sends the sheet to the position to be processed. At the same time, the mold selection system selects the corresponding mold in the mold library, and the hydraulic power system presses according to the program to automatically complete the workpiece processing.
In August, the turret punch attracted attention from Suzhou Yawei CNC turret punch, Yangli group MP series CNC turret punch, Qingdao Dadong technology turret punch, etc.
Introduction to turret punch processing station:
The universal thick turret mold is generally graded according to the hole size that the mold can process, which is convenient for the selection of the mold. It is usually divided into five grades: A, B, C, D and E.
A (1 / 2 ") station: processing range Ø 1.6 ~ Ø 12.7mm
B (1-1 / 2 ") station: processing range: 12.7 ~ 31.7mm
C (2 ") station: processing range Ø 31.7 ~ 50.8mm
D (3-1 / 2 ") station: processing range: 50.8 ~ 88.9mm
E (4-1 / 2 ") station: processing range: 88.9 ~ 114.3mm
The turret punch can punch many holes and shapes with different diameters at one time, and the mold is relatively simple, and the whole process is automatic. The ordinary press is the opposite of the above.
0 is tensile strength, the theoretical punching pressure is 31 tons, it is recommended to select 40 tons (45 tons) punch press, the calculation formula is: P = k * ζ * L * B, where p is the blanking force, K safety factor, take 1, and the middle value is about 345. The shear strength of a 3 steel plate is 304-373 MPa. 8 times, l is the perimeter of stamping product, B is the thickness of material, 6-0, and ζ is the shear strength of material
Turret CNC punch most are for thin plate processing, generally less than 6 mm thick cold plate with it to punch! However, it also follows the principle of general punch and punching thickness, that is to say, how many tons of punching force it has at one time! It's no different from ordinary punch press! Its big advantage is that you want to punch how big the hole, in the programming given the size of the hole, it will row its own knife to cut you out of this hole, you want to use it to punch thick cold plate, you have to choose a small station mold, with automatic row tool to complete it! One thing you should pay special attention to!!! The mold it chooses must be the same as the ordinary punch die. How thick the plate is, there must be a corresponding gap between the upper and lower dies, otherwise the punch will be damaged and the mold will be destroyed!!!
