Abstract

The invention discloses an ejection device used for cold upsetting manufacturing. The ejection device comprises a work box. A cold upsetting rotator supporting rod penetrates through the top of the work box. The top of the work box is connected with a cold upsetting rotator through the cold upsetting rotator supporting rod. The cold upsetting rotator comprises a cold upsetting fixing groove located in the side surface of the cold upsetting rotator and the cold upsetting rotator supporting rod fixed to the bottom of the cold upsetting rotator, and the cold upsetting fixing groove is connected with the cold upsetting rotator supporting rod through the cold upsetting rotator. The cold upsetting fixing groove is formed in the side surface of the cold upsetting rotator, an ejection rod is arranged at the bottom of the cold upsetting rotator, an air cylinder is arranged at the bottom of the ejection rod, a buffer thread is arranged on the inner side of the air cylinder, a return quick draining valve and a pressure stabilizing valve are arranged on one side of the work box, a quick draining valve silencer is arranged at one end of the return quick draining valve, and a pressure stabilizing valve meter is fixed to the front face of the pressure stabilizing valve; and according to the ejection device, through the cold upsetting rotator, the buffer thread, telescopic rods, telescopic springs and the like, the purposes that the protection effect of the device is improved and the device is convenient to dismount and mount are achieved.

Description

Technical field [0001] The invention relates to the technical field of component manufacturing structure equipment, in particular to an ejector device for cold heading manufacturing. Background technique [0002] Cold heading is a forging method in which a metal bar is upset (usually partial upsetting) by a mold at room temperature. It is usually used to manufacture the heads of screws, bolts, rivets, etc., which can reduce or replace cutting processing. The forging material can be It is copper, aluminum, carbon steel, alloy steel, stainless steel, titanium alloy, etc. The material utilization rate can reach 80% to 90%. The cold heading is mostly performed on a dedicated cold heading machine, which is convenient for continuous, multi-station, Automated production, cutting, heading, accumulation, forming, chamfering, thread rolling, diameter reduction and trimming can be completed in sequence on the cold heading machine. The production efficiency is high, up to 300 pieces per minu...
