Closed CNC punch

Closed CNC punch is the abbreviation of closed CNC turret punch, corresponding to open CNC punch. The function is more comprehensive and the operation is simpler. It is not difficult for technical workers to use the equipment. Let's take a look at the closed CNC punch press and open
Closed CNC punch is the abbreviation of closed CNC turret punch, corresponding to open CNC punch. For workers, it is easier to operate the equipment. Let's take a look at the difference between the closed CNC punch and the open CNC punch, mainly from their respective advantages and disadvantages to carry out comparative analysis.
 
The differences between closed CNC punch and open CNC punch press are mainly shown in the following aspects:
 
First of all, in terms of throat depth and punching pressure, the rear body of open CNC punch is generally 1250mm. Once it exceeds 1250mm, the machining accuracy will be seriously affected, so these are extremely unfavorable to some manufacturers with higher requirements for machining accuracy. The closed CNC punch completely overcomes the disadvantage of open CNC punch, and its throat depth can reach 1500mm. above. In addition, when the throat depth of the open CNC punch is 1250mm, the punching pressure is about 25 tons, which is difficult to reach 30 tons. The impact pressure of the closed CNC punch can reach more than 30 tons, and the performance of the closed CNC punch in this respect is slightly better.   
 
Secondly, in terms of machining accuracy, when the turret of the open CNC turret punch is changed, the adjustment is more troublesome, and the parallelism between the feeding platform and the punch is difficult to guarantee, which is prone to tilt, resulting in the burr of processed products. This is the open CNC punch in the use process to make users more headache. The manufacturer's pursuit of high efficiency, high speed and high precision of CNC punch press has indeed improved its technical performance, but this has made the operator become an obstacle to the performance of the machine tool. This is because the manual loading and unloading and mold changing operations take up too much auxiliary time, and the operator has become the slave of the machine tool, which is more and more unsuitable for the high productivity requirements of the machine tool. Therefore, the automatic loading and unloading device of punch and the automatic mold changing device of external mold library have been put on the agenda as a part of the high-efficiency CNC punch, resulting in the closed CNC punch. There is no burr and other problems in the use of closed CNC punch, because the turret of the closed CNC punch is integrated when changing the mold. Automatic adjustment, production and processing are carried out in one go. To a great extent, the accuracy of processing is guaranteed and such problems are avoided.   
 
* in terms of processing efficiency. In order to ensure the machining accuracy, the stamping times of open CNC punch press are about 220 and 160 at low speed. If more than * high stamping times, not only the machining accuracy is difficult to guarantee, but also the wear of the machine is very serious. The closed CNC punch can reach 180 times at low speed and 260 times at high speed on the premise of ensuring the accuracy, which greatly improves the production efficiency.   
 
CNC presses are more popular in today's market. In the field of sheet metal processing, the closed CNC punch has developed rapidly with its remarkable advantages, and the technology has been continuously innovated, which has the trend of gradually replacing the open CNC punch.
