Valve spring base cold heading forming equipment

Abstract

The invention discloses valve spring base cold heading forming equipment. The valve spring base cold heading forming equipment comprises a machine base. A steel cropping station and a plurality of cold heading stations are arranged on the machine base side by side. Each cold heading station is provided with a die core and an extrusion ejector rod. Each die core is provided with a cavity matched with the corresponding extrusion ejector rod. Each cavity is internally further provided with a cavity ejector rod for jacking and conveying a formed blank out. A blank transmitting device is further arranged among the multiple cold heading stations. The blank transmitting device comprises an installing base, the part, corresponding to the position between every two adjacent cold heading stations, of the installing base is provided with a clamping and conveying head, and the installing base is connected to the machine base through a swing arm. By adoption of the above structure, the valve springbase cold heading forming equipment simpler in structure and higher in production efficiency is provided.

Description

technical field [0001] The invention relates to a processing equipment for forming a valve spring seat by cold heading. Background technique [0002] The valve spring seat is an important part of the engine valve train, and its structure is as follows: figure 1 Shown is cylindrical and has two steps with a central through hole. At present, there are two main methods of processing and forming the valve spring seat: one is to process the corresponding steps on the formed cylindrical blank by cutting or milling, and then punch holes. This processing method not only has low production efficiency, but also The waste of steel raw materials is serious; the other is to form by cold heading, that is, after cutting the steel into a small section, and then pass through multiple cold forging stations for cold heading, but because each existing cold heading station is in the Work under their respective power sources, so not only the overall structure of the equipment is complicated, bu...

At present, there are two main methods of processing and forming the valve spring seat: one is to process the corresponding steps on the formed cylindrical blank by cutting or milling, and then punch holes. This processing method not only has low production efficiency, but also The waste of steel raw materials is serious; the other is to form by cold heading, that is, after cutting the steel into a small section, and then pass through multiple cold forging stations for cold heading, but because each existing cold heading station is in the Work under the respective power sources, so not only the overall structure of the equipment is complicated, but also multiple cold heading stations cannot be operated synchronously, resulting in low production efficiency
