Problems solved by technology

[0003] At present, some manufacturers have adopted the method of cold rolling to make flat welding flange blanks. Although the production efficiency has been improved, the straight sections at the head and tail cannot be ruled out. Can not be fully utilized, but also increased production costs
And can only roll one at a time, the efficiency is still very low

Abstract

The present invention relates to a hot rolling machine of a flange roughcast, which comprises a stander, a power machine that is fixed on the stander, a reducer, a bearing box and a flat-steel guiding device, wherein, a main shaft passes through and is arranged inside the bearing box; one end of the main shaft is connected with the output shaft of the reducer through a coupler, and the other end is provided with a disc-shaped curling mold; the edge of the curling mold is provided with an end clip; a hydraulic jacked device is arranged in the same plane of the curling mold; a jacked wheel is arranged at the end of the jacked device. The hot rolling machine of the flange roughcast saves material, and has high processing precision, high processing speed and high production efficiency, and is favorable to be popularized.

Description

1. Technical field [0001] The invention relates to a professional equipment for making flanges, in particular to a flange blank hot coiling machine. 2. Background technology [0002] With the rapid development of the economy, the pipeline transportation projects of various liquids and gases in our country are more and more widely used. Therefore, the flat welding flange has become an indispensable supporting product. The flat welding flange is to make the flange blank first, and then finish the flange blank, so the processing cost depends on the accuracy of the flange blank. At present, the production of flange blanks mainly adopts forging forming and cutting forming. There is common shortcoming in these two kinds of preparation methods. One is that the processing is rough and the geometrical size error is large, which increases the labor intensity and processing cost of the finishing process and reduces the yield of finished products; the other is that the production eff...
