Numerically controlled notching press and method for controlling notching process by using computer program

Abstract

The invention discloses a numerically controlled notching press, which comprises a machine body, a power mechanism, a toggle rod mechanism, a die, a chip pressing device, a chip unloading device, a dividing apparatus, a radial feeding device, a pressure system and a lubricant system, wherein a slider of the toggle rod mechanism consists of a slider body and a sliding core; the sliding core is provided with an eccentric shaft which is connected with an oscillating cylinder; the platform surface of the machine body is fixed with a lower die guiding rail; the bottom surface of a lower die is fixed with a lower die sliding rack; the lower die slides on the lower die guiding rail through the lower die sliding rack; the top surface of an upper die is fixed with an upper die guide frame in whicha guide plate capable of relatively sliding is arranged; the top part of the guide plate is fixed with a positioning column connected with the slider of the toggle rod mechanism; and the lower die sliding rack is connected with a tangent feeding device. The numerically controlled notching press is suitable for intermittent notching, ordinary chip notching, conical groove chip notching, spiral groove chip notching and slant and straight groove chip notching, and has a wide application range. A notching process of the notching press is controlled by adopting a computer program.

Description

technical field [0001] The invention relates to a numerically controlled notching machine and a method for controlling the notching process by using a computer program. Background technique [0002] The Chinese Invention Publication No. is CN 101244441A, which discloses a main engine of a CNC punching machine, including a frame, a workbench, a punch, an indexing device, a stamping device that drives the punch to move up and down, and a drive workbench. A moving radial feed device, an air pressure system, and a tablet pressing and unloading device controlled by the air pressure system. The stamping device above includes a power mechanism and a toggle mechanism. The power mechanism includes a variable frequency speed regulation motor, a small pulley installed on the frequency conversion speed regulation motor main shaft and a large flywheel connected to the crankshaft. There is a pneumatic clutch device that integrates clutch and brake, and the pneumatic clutch device is prov...

AI Technical Summary

Problems solved by technology

Because the conductor has a certain width and thickness and high rigidity, in order to facilitate installation, the groove shape on the iron core is required to be an oblique straight groove instead of a spiral groove, which requires that the corresponding grooves of the front and rear chips have 1 to The offset of 3 wires means that the die and the chip can move tangentially relative to each other, that is, the die and the machine table can move tangentially relative to each other. The die of the CNC punching machine with the above structure cannot move tangentially, so it cannot process oblique Straight slot core chips
