The current use of the press on the punch and table between the closure height adjustment, are through the crankshaft between the crankshaft rod and punch set with a set of threaded nut and worm gear adjustment device, the punch press this device to achieve the closure of the height adjustment . The gantry punch is concerned, if the use of worm gear adjustment device to adjust the height of the mold after the end of the mold is not locked, then there will be a lot of punching process between the punch and the table closed height changes, this time will not only affect To the punch press accuracy, but also cause damage to the mold, and hydraulic punch lock punch device is a punch after the punch to adjust the special device lock. Punch hydraulic lock punch device consists of punch, lock head, saw tooth rod, piston, worm, worm and fixed block composition, which punch through the screw fixed to the top punch press; punch cover serrated rod, piston socket in The lower end of the punch is provided with an oil inlet port to supply oil to the oil chamber; the fixing block is fixed on the upper end of the punch by the screw and the saw rod is restricted to the upper end of the punch rod; the lower end of the punch rod forms a closed oil chamber between the piston and the punch; A worm wheel is arranged in the punch and is connected with a saw tooth rod; the worm is arranged at one end of the fixed block, is connected with the worm wheel; the worm is provided with an external tooth, and the outer end of the worm wheel is provided with External teeth copper bending machine, as well as rotating worm to drive the worm wheel rotation; serrated rod shaft with external teeth, worm gear inner end with internal teeth. In the actual use of the gantry press equipped with the hydraulic lock punch device, the worm wheel is driven to rotate by the worm wheel, and the sawing rod is adjusted by the worm gear teeth to easily adjust the closing height between the punch press and the table, and the hydraulic drive piston drives the saw tooth Rod metal fabrication, so that the teeth of the saw tooth rod and the inner end of the combination of teeth to achieve punch press locking cylinder clamping clamping to avoid the internal teeth of the loose teeth and teeth from the internal teeth to eliminate the gap to ensure that The bottom of the punch press the bottom of the state of stability. IPM punch electronic cam with high-precision rotary transformer, the angle of the sampling data more real-time and accurate, and can achieve multi-point speed and shutdown control, the punch can be applied to the complex punch on the molding, and the use of common interface can simplify the external environment . IPM Punch electronic cam control device can real-time monitoring of the press brake stop characteristics, and in accordance with its characteristics in the operation of the gradual changes in the automatic control of fixed-point stop to adjust. The electronic cam control device of the punching machine receives the analog signal of the rotary transformer through the analog input interface and the cam control device converts the electrical signal of the rotary transformer by the A / D conversion circuit to convert the analog signal representing the physical value of the punch into high speed sampling to corresponding 12-bit digital coding, digital coding real-time transmission to the cam control device CPU for processing bus bar bending machines. The CPU confirms the crank speed and the current crank angle position of the current punch according to the obtained high frequency sampling rotation angle value, and obtains the speed change rate through the differential algorithm.
