Problems solved by technology

[0008] For this reason, the technical problem to be solved by the present invention is that when the ejector device of the press in the prior art realizes the ejection of the forging workpiece with a relatively complex structure in the automatic production line, it is easy to cause the workpiece to lose its If it is too large to bounce out of the cavity and cannot fall back to the original position, the automatic line is interrupted. Provide a press inertial ejection device that can control the bounce of the workpiece in the cavity when the workpiece is loosened and a pressure Inertial ejection method of workpiece on machine

Embodiment Construction

[0027] like Figure 4-5 As shown, a kind of press inertial ejection device of the present embodiment 1 includes a ejector rod 7, and an ejector rod driving mechanism that drives the ejector rod 7 to make up and down linear reciprocating motions, and the ejector rod A counterweight 8 is movable on the 7, and the mass of the counterweight 8 is more than 10 times the mass of the ejector rod 7 and the workpiece. Because the mass of the ejector rod 7 increases greatly under the increase of the counterweight 8, at the moment when the workpiece is loosened, the existence of the counterweight 8 reduces the potential energy stored by the ejector rod driving mechanism due to elastic deformation. Release speed, the smaller speed obtained by the ejector rod 7 and the workpiece is not enough to make the workpiece bounce out of the cavity, and under the condition of obtaining the same large elastic deformation energy, the bounce height of the workpiece will be no greater than before 1 / 10 o...

Abstract

The invention relates to an inertia ejection device for a pressing machine. The inertia ejection device for the pressing machine comprises an ejector pin (7) and an ejector pin driving mechanism for driving the ejector pin (7) to move back and forth vertically and linearly; a balance weight (8) is arranged on the ejector pin (7); and the mass of the balance weight (8) is not less than 10 times of that of the ejector pin (7). According to the inertia ejection device for the pressing machine, through the arrangement of the balance weight (8) on the ejector pin (7), when being ejected, a workpiece is controlled to bound in a cavity, so that automatic and smooth workpiece conveying can be is ensured.

Description

technical field [0001] The invention relates to an ejection device of a press for forging or stamping and a method for inertial ejection of workpieces on the press. Background technique [0002] In forging, especially in die forging, since the mold has a relatively complex cavity, the workpiece will usually be stuck in the mold after forging, so the general press will be equipped with a workpiece ejection device. At present, the commonly used ejection devices mainly include the following three Forms: [0003] The first type is purely mechanical (as attached figure 1 ), the ejection force of this type of ejector device comes directly from the rotation of the eccentric shaft of the equipment. The cam installed at one end of the eccentric shaft drives the pull rod to move up and down, the pull rod drives the lower swing rod to swing up and down, and the lower swing rod drives the eccentric belt connected to it. The ejector beam reciprocates to drive the ejector rod to move...
