Stamping die with ejection device and with accurate positioning function

Abstract

The invention discloses a stamping die with an ejection device and with an accurate positioning function. The stamping die comprises a stamping head and a lower die, wherein a die cavity of the lower die is provided with an arch hollow cavity; the stamping head is externally sleeved by a stamping head fixing sleeve; an inclined step is arranged at the upper end of the stamping head, and is in fit with the conical surface of the inner wall of the stamping head fixing sleeve; the top of the stamping head is connected to a power mechanism; a displacement sensor is arranged above the side of the lower die, and is connected to a control device; a movable ejector rod is arranged below the lower die, and is right opposite to the die cavity of the lower die; the lower end of the movable ejector rod is connected to a cylinder; the cylinder is connected to a control device; and the power mechanism is a hydraulic cylinder and a piston. The step of the stamping head and the fixing sleeve are matched with each other, the installation stability of the stamping head is good, and the stamping accuracy of a product is high; as the movable ejector rod is arranged below the lower mold, a processed work-piece can be conveniently taken out, so that the production efficiency is improved.

Description

technical field [0001] The invention relates to a stamping die, in particular to a stamping die with accurate positioning and an ejection device. Background technique [0002] The punch is also called punch, upper die, male die, punching needle, etc. The punch is a metal part installed on the stamping die. It is used in direct contact with the material to deform and cut the material. Die punches generally use high-speed steel and tungsten steel as materials, and there are high-speed steel punches and tungsten steel punches. The die installed on the press is directly in contact with the material (metal or non-metal) after the die punch is assembled, so that the material is separated or plastically deformed to obtain the desired part. [0003] When processing some metal parts, the high-speed punch is not stable due to its own inertia, and will produce slight vibration, which will affect the product quality. When the stamping is completed and taken out, the workpiece will be p...

AI Technical Summary

Problems solved by technology

[0003] When processing some metal parts, the high-speed punch is not stable due to its own inertia, and will produce slight vibration, which will affect the product quality. When the stamping is completed and taken out, the workpiece will be pressed tightly on the lower mold, which is difficult to remove. affect work efficiency
