Long-axis tooth-shaped cold extruding self-ejecting system device

Abstract

The invention discloses a long-axis tooth-shaped cold extruding self-ejecting system device. The long-axis tooth-shaped cold extruding self-ejecting system device comprises a first sliding block stroke cylinder body, a second sliding block stroke cylinder body, a nitrogen spring pedestal, a nitrogen spring, a first sliding block, a second sliding block, a baffling plate, a cushion block, a die, a material barrel die, a material barrel die external sleeve, a pressing rod, a pressing cover and an ejecting rod. The long-axis tooth-shaped cold extruding self-ejecting system device disclosed by the invention has a small appearance, convenience for taking out parts, high production efficiency, and capability of achieving automatic production.

Description

technical field [0001] The invention relates to a cold extrusion system device, in particular to a long-axis toothed cold extrusion self-ejection system device. Background technique [0002] During the spline forming process of long-axis parts, the operator needs to operate the press button to make the ejector pin push out the formed part upwards. This method is inefficient and the labor intensity of the workers is high. [0003] Due to the long length of the parts, it is often inconvenient to take out the parts due to the stroke of the press during the forming process. In addition, in the tooth-shaped extrusion process of small-shaft parts, the slider in the ejection system device is smaller, so that the shape of the forming die is correspondingly smaller; in the long-shaft large-diameter parts, due to the large forming force, Therefore, the corresponding mold dimensions are also very large, causing inconvenience to production and use. Contents of the invention [0004]...
