Punching speed with punching die high – speed stamping automatic production continuity


Punching speed with the die high-speed stamping automatic production continuity, the feeder is necessary auxiliary equipment, and the feeder material itself from the accuracy of the feeding time, the key factor is decided by the product quality, feeder feeding time punch adjustable , Feeding time I punch the assembly unit is usually 270 degrees to 90 degrees over feeding, feeding, feeding time setting, basically able to meet the needs of most high-speed stamping production, but in the actual stamping production, the customer needs feeding time According to different products and different punch speed re-adjust the settings, it is particularly important in the correct adjustment, Yuda mechanical roller punching machine usually mix the material feeder timing adjustment mode, CNC servo feeder, pneumatic feeder were discussed:

1, the roller feeder is the punch material model matching to the most, feeding time adjustment eccentric disc changes and punch to achieve the connection, the actual operation is very simple, the first punch operation to stop the feed angle scale ring, and then adjust the roller feeder screw In the eccentric disc, make it into a straight line can pull rod. Special Note: Roller feeder to complete the feed to 180 degrees, which began feeding until 260, when the punch when the run 80 degrees to feed it to complete, so the roller feeder feeding time adjustment between 190-350 degrees.

2, CNC machine tool servo drive, can also achieve multi-stage feeding, feeding adjustment time is through the signal line to connect the punch cam to achieve, because my punch using electronic cam, so that delivery time is very simple to set up , Just enter the required feeding time in the punch press on the touch screen punch corner.

CNC punching machine
3, Pneumatic Feeder Feeder is the most economical, it is used punching, feeding time set in two ways, one is the standard pneumatic feeder, which is used to guide the rod installed in the press under the slider pressure floating rod to complete Feeding movement, the feeding time length of the pressure setting adjustment guide rod, the length of the guide rod, feeding time is late; another equipped with water supply pneumatic valve pneumatic feeder, and CNC servo feeder feeding time setting method is Same, that is, in my punch press touch screen set.

Punch in time to effectively extend the life of the mold

Timely grinding can effectively extend the service life of the mold

If abnormal noise artifacts occur with excessive burrs or stamping, the mold may be very sluggish. Check the convex and concave die when the arc edge wear radius is about 0.1 in the grinding.

Practice shows that often rather than grinding until the mill can not be re-grinding, not only will maintain a good quality of the workpiece to reduce the punching force, you can also die life doubled.

In addition to grinding in the mold, to master the correct grinding method is particularly important. Mold grinding process is as follows: 1) the use of sintered alumina wheel, hardness ~, particle size 46 ~ 60, high-speed steel wheel grinding the best choice. 2) grinding, slotting or vertical fixture will punch card machine magnetic chuck, each grinding 0.03 ~ 0.05, repeat until the sharp perforation, the maximum grinding volume is generally 0.1 to 0.3.

3) When the grinding force is large or close to the wheel mold, the mold coolant can prevent overheating and cracking or annealing, the manufacturer should be consistent with the requirements of high-quality multi-purpose coolant.

4) Wheel unloading 0.03 ~ 0.08, transverse feeding 0.13 ~ 0.25, horizontal feeding rate 2.5 ~ 3.8 /. 5) After grinding, cutting edge burr, grinding stone, grinding radius of 0.03 ~ 0.05, can prevent edge cracks.

6) magnetic treatment and spray lubrication, to prevent rust.

Analysis of the Impact of Electromagnetic Interference Loss

Electromagnetic interference loss is the biggest problem punch, the main source of power semiconductor devices in the switching process, the device current and voltage caused.

In the punch of the various losses, the electromagnetic interference generated by the loss in the power supply service to a certain degree of high will stutter contempt. On the one hand IPM punch cnc machining center electromagnetic interference own loss of energy, busbar machine is the progress of power efficiency is always necessary to soft-switching capability or zero-voltage switching or zero-current switching technology, the use of these technologies slow down the switching process voltage and current speed Eliminating the switch process, the electromagnetic interference becomes very small, do not like the conventional switching power supply circuit need to deliberately build a circuit to suppress electromagnetic interference.
The same size of the power of the punch press the same power dissipation, so IPM punch beveling machine, want to get more output power, destined to improve efficiency, while high power efficiency roughly reduce the power semiconductor device stress, Improve its conciseness.

Punch the switch and the IPM punch IPM punch IPM punch output rectifier diode can be concluded zero-voltage switch or zero current switch, the efficiency can be significantly improved.

How reasonable grinding grinding machine punch mold?

Ordinary mold not only punch manufacturers can improve the service life of the mold, but also can improve the service life of the machine, so master the correct and reasonable grinding time is very important. The mold needs to be sharpened by the user is very direct method is: punching accumulated to a certain extent, check the quality of the stamping whether there is a larger burr, again check the mold edge is round (rounded ≥ 1) . If this happens, the press has been dull, this time the need for grinding.

If the mold is sharpened at the appropriate time, the service life can be extended by 3 times, but without proper edge grinding, but will quickly increase the edge damage of the mold, reducing its life, mold grinding machine with its matching edge grinding, choose the right edge Grinding machine will greatly facilitate the user, improve production efficiency.
