Detailed Description

The invention is described in further detail below with reference to the figures and the specific embodiments.

As shown in fig. 1 to 3, a forging ejection device for automatic blade forging comprises an ejection rod 1, an ejection rod seat 2 and a return spring 3; a mandril mounting hole 5 is vertically formed in the lower die 4 of the die, the mandril mounting hole 5 adopts a two-stage stepped hole structure, a large-diameter hole is positioned at the lower side, and a small-diameter hole is positioned at the upper side; the ejector rod seat 2 is positioned in the large-diameter hole at the lower side of the ejector rod mounting hole 5, and the ejector rod seat 2 only has axial movement freedom in the large-diameter hole at the lower side of the ejector rod mounting hole 5; the ejector rod 1 is positioned in the small-diameter hole on the upper side of the ejector rod mounting hole 5, and the ejector rod 1 only has axial movement freedom in the small-diameter hole on the upper side of the ejector rod mounting hole 5; the lower end of the ejector rod 1 is fixedly connected with the upper end of the ejector rod seat 2 in a threaded manner; reset spring 3 is located between the ladder face of ejector pin seat 2 and ejector pin mounting hole 5, and reset spring 3 suit is in the ejector rod 1 outside.

The ejector rod base 2 adopts a two-stage step rod structure, and the large-diameter end of the ejector rod base 2 is in sliding contact fit with the large-diameter hole at the lower side of the ejector rod mounting hole 5.

The large-diameter end of the ejector rod seat 2 and the large-diameter hole on the lower side of the ejector rod mounting hole 5 have the same cross section shape, and both the cross section shapes are cut edge circular.

The body of rod bottom of ejector rod 1 is equipped with external screw thread 6 the internal thread hole 7 has been seted up at the big footpath end center of ejector rod seat 2, and ejector rod 1 passes through body of rod bottom external screw thread 6 and the internal thread hole 7 spiro union fixed coordination at 2 big footpath end centers of ejector rod seat.

The guide groove 8 is formed in the orifice of the internal thread hole 7 in the center of the large-diameter end of the ejector rod seat 2, and is used for ensuring that the external thread 6 at the bottom end of the rod body of the ejector rod 1 can be quickly and accurately screwed with the internal thread hole 7 in the center of the large-diameter end of the ejector rod seat 2.

When the ejector rod 1 is in an ejection state, the lower end face of the small-diameter end of the ejector rod seat 2 is flush with the bottom plane of the lower die 4 of the die.

When the ejector rod 1 is in an initial non-ejection state, the lower end face of the large-diameter end of the ejector rod seat 2 is flush with the bottom plane of the lower die 4 of the die.

When the die mounting, pack into the big footpath hole of downside of ejector pin mounting hole 5 with reset spring 3 and ejector pin seat 2 earlier in proper order, after the lower mould is gone up in the installation, lift up the mould again, then in inserting the upside path hole of ejector pin mounting hole 5 with the one end that is equipped with external screw thread 6 on ejector pin 1, lean on ejector pin seat 2 until the lower extreme top of ejector pin 1, later revolve and twist ejector pin 1, until in the internal thread hole 7 at the body of rod bottom external screw thread 6 screw in ejector pin mounting hole 5 big footpath end center of ejector pin 1, screw completely until ejector pin 1.

When the ejection block below the die is lifted upwards, the ejection rod seat 2 and the ejection rod 1 are driven to ascend synchronously until the ejection rod 1 ejects the forged piece out of the die cavity, and the return spring 3 is in a compressed state at the moment. When the ejection block below the die descends and resets, under the action of the spring force of the reset spring 3, the ejector rod seat 2 falls back and resets under the jacking force of the reset spring 3, and simultaneously drives the ejection rod 1 to fall back and reset.

The embodiments are not intended to limit the scope of the present invention, and all equivalent implementations or modifications without departing from the scope of the present invention are intended to be included in the scope of the present invention.
