The accuracy of the feed in the real use of the punch machine is one of the necessary elements in judging the performance and great of the punch machine, and it additionally immediately determines the satisfactory of the finished product in the stamping process. Therefore, for stamping customers, the accuracy of the feed computer is one of the core elements involved by using customers. However, the feed accuracy of the punch computing device is not a regular layer, however, is affected with the aid of many factors. The following is a designated clarification of the major factors affecting the accuracy of the feed computing device with the aid of Haiwei.The accuracy of the feed in the real use of the punch machine is one of the necessary elements in judging the performance and great of the punch machine, and it additionally immediately determines the satisfactory of the finished product in the stamping process. Therefore, for stamping customers, the accuracy of the feed computer is one of the core elements involved by using customers. However, the feed accuracy of the punch computing device is not a regular layer, however, is affected with the aid of many factors. The following is a detailed explanation of the main factors affecting the accuracy of the Press feeding equipment by Haiwei.
1. The factors on the resolution of the punch machine. There are many kinds of punch feeder, generally used air feeder, curler feeder, NC servo feeder, of which the air feeder has the lowest accuracy (usually ± 0.08 mm), and the roller feeder has the middle accuracy (usually ± 0.05 mm).), The NC servo feed laptop has the perfect accuracy (usually ± 0.02 mm). At the same time, extraordinary producers have a distinctive material selection, processing processes, and assembly, and the accuracy is also different.
2. The cloth of the feed material is additionally extraordinary accuracy. In particular, when the material floor is very smooth, the fabric thickness is thin, the surface is without difficulty damaged, and the cloth is a skinny tape material, the accuracy is without difficulty affected. This type of cloth wishes to be wrapped by way of the PU wheel treatment of the drum of the punch feeder to make sure the feeding accuracy.
3. Feed speed, feed step distance make bigger will also affect the feed accuracy. When these two gadgets are increased, the accuracy of feed will be notably reduced.
4. The punching dies whether there is an information pin, guide pin positioning accuracy. The rest function of the punch feeder is to make certain that the cumulative error is eradicated and the accuracy of the feed is stable. If there is no guide pin or the information pin positioning accuracy is not high, the feed feeder will have a large cumulative error after long-term use.
5. The effect of exterior factors on the accuracy of feed equipment:
A. External factors affecting the accuracy of the air feed computer encompass the air source stress (not too giant or too small), whether the O-ring is worn(lubricating oil wishes to be many times delivered to the air feed machine's three-point combination, The damaged O-ring is replaced), the feeding computing device relaxes the time(the stamping process that wants to be matched and punch), the velocity adjustment screw adjustment is now not accurate, and the feeding step distance is too long.
B. External elements affecting the accuracy of the roller feeder are the compression strength of the press spring(just appropriate, Not too loose or too tight), material itself(bending, uneven, margin), brake machine with oil(resulting in retrogression of feed), cross joint too unfastened or worn, leisure time is now not correct, material thickness adjustment is no longer correct, etc..
C. External elements that have an effect on the accuracy of the NC servo feed laptop consist of the air supply strain (not too large, not too small), the compression strength of the press spring(need to be just right, Can't be too unfastened or too tight), fabric itself problems(bending, uneven, side fabric with bristle), servo motor and other digital control aspects selection, feed time adjustment, relaxation time adjustment.
