Problems solved by technology

[0002] In the prior art, scrap steel needs to be heated in a scrap steel furnace, and a thermal energy delivery system is generally used in the process of heating scrap steel, and the burner is one of the most important components in the above-mentioned thermal energy delivery system; since the burner has a certain Inclination, and uniform holes need to be made on the inclined surface and the vertical surface, so the production is more difficult; currently, most enterprises use CNC lathes and other processing tools for production, and the processing generally includes turning, polishing, turning the inner diameter and boring And other processes, because the burner is small and there are problems of uniform opening, opening of holes on the inclined surface and vertical surface, resulting in difficult processing and low processing efficiency, generally speaking, the above process can be processed in about 2 hours. One piece of burner; due to the cumbersome and inefficient processing of CNC lathes, some companies began to try to use forging to press, but in the process of forging, there are problems in the centering of the blank, the difficulty of hole processing, and the forging process. Problems such as fracture are prone to occur in the medium, which directly leads to defects of low yield

preparation example Construction

[0054] A preparation process for preparing tooling for a burner for a scrap steel furnace, the preparation process comprising the following steps:

[0055] Step 1: Determine the diameter of the tablet according to the size of the burner, and prepare the tablet by blanking according to the diameter of the tablet;

[0056] Step 2: using a drilling device to make holes on the prepared blank, the hole making position is the position of the inner hole 23 after the burner is formed, so that the inner hole 23 of the burner is formed;

[0057] Step 3: Place the blank in the positioning ring 8, and the outer diameter of the blank is clamped in the inner diameter of the positioning ring 8; at the same time, place the positioning ring 8 on the top of the lower die 3, start the forging device to make the upper die 4 go down for positioning The blank in the ring 8 is initially forged; after the preliminary forging, the blank falls into the lower die 3 and shrinks the blank to the middle, s...
