Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] see figure 1 , a billet positioning device for large die forgings, including a base 1, a support table 2, a telescopic device 3 and a positioning pincer 4. Wherein, the supporting platform 2 is arranged on the base 1 . During specific implementation, the side of the support platform 2 in contact with the base 1 has an outwardly protruding installation boss, so that the section of the support platform 2 has an inverted T-shaped structure. There are several threaded holes on the mounting boss, and strip holes are opened on the base 1 corresponding to the positions of the threaded holes, and the length direction of the strip holes is perpendicular to the length direction of the cylinder 31 . The base 1 and the support table 2 are fixedly connected by bolts passing through strip holes and threaded holes. In this way, the relative position between t...

Abstract

The invention discloses a blank positioning device and a positioning method for a large die forging. The blank positioning device for the large die forging comprises a base, a supporting table, a telescopic device and a positioning tong head; the supporting table is arranged on the base; the telescopic device is located on the supporting table and comprises an air cylinder and a sliding rod, the air cylinder is provided with a piston rod, the piston rod is fixedly connected with one end of a sliding rod through a connecting plate, and the other end of the sliding rod is fixedly connected with a positioning tong head; the positioning tong head is provided with two tong arms, the adjacent sides of the two tong arms are inclined faces, and the distance between the ends, close to the sliding rod, of the two tong arms is smaller than the distance between the other ends of the two tong arms. According to the blank positioning device, the large die forging can be accurately positioned, the working efficiency is improved, die forging materials are saved, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of material forging, in particular to a blank positioning device for large die forgings and a positioning method thereof. Background technique [0002] In the production of large-scale die forgings, the weight of large-scale die forgings is greater than that of the blank, and the forgings are often complex in shape, so the shape of the mold cavity is correspondingly complex. When placing the billet, the high-temperature billet is usually transferred from the heating furnace to the mold by a tong truck, and the billet is positioned by the operator's visual inspection during the placement process. Due to the influence of factors such as the visual angle change of the standing position of the person, the high temperature radiation of the material, the weight of the blank, and the operation safety in such a blank positioning method, it is easy to generate a large error, which makes the blank in the process of pl...
