Embodiment 1
[0022] This embodiment provides a method for mass-producing right-angle square steel using a precision forging machine. The precision forging machine is a 16MN horizontal precision forging machine, the programming software for automatic control is BarForge, and the square hammer head model is F60×G120; steel material products The model is 30CrMo, the weight of the billet is 4.35t, the specification is φ450*3450mm, and the size of the finished right-angle square steel is 222×171mm.
[0023] The specific preparation method is:
[0024] Step 1. Blank heating:
[0025] Put the billet into a gas-fired heating furnace to heat, the heating temperature is 1220-1240°C, and the holding time is 4 hours, so that the billet should be heated uniformly and thoroughly burned, and the billet is air-cooled when it is released from the furnace.
[0026] Step 2. Forging by precision forging machine:
[0027] The total forging ratio in the forging process is 4.2, and there are 9 forging passes i...

Abstract
The invention relates to a method for batch-producing right-angled square steel by using a precision forging machine, and belongs to the technical field of right-angled square steel preparation methods. In order to improve the production efficiency of right-angled square steel and reduce cost consumption, the present invention provides a method for mass-producing right-angled square steel using a precision forging machine. The forging uses a square hammer head and forging is carried out in two stages. The first stage is mainly deformed. , a total of 3 to 5 passes are carried out, and the cylindrical billet is forged to a rounded slab; the second stage is mainly for forging a right angle, and a total of 4 passes are carried out; the rounded slab is forged to a right-angled square. Finished right angle square steel. The invention can complete the production of a 15-meter-long right-angle square steel within 10 minutes, reduces the number of fires and the finished product rate under the condition of reducing the margin, significantly improves the production efficiency, reduces the production cost, and realizes the right-angle square steel Automated, high-precision mass production. The invention can improve the production efficiency of equipment operation, is convenient for organizing production, and has a high qualified rate of products.
Description
technical field [0001] The invention belongs to the technical field of preparation methods of right-angled square steel, and in particular relates to a method for mass-producing right-angled square steel by using a precision forging machine. Background technique [0002] In terms of cross-sectional shape, forging steel is the most widely used bar, followed by square steel. Square steel can be divided into right-angle square steel and rounded square steel according to its shape. Because the right-angled square steel is prone to cracks at the sharp corners, and the right angle is not easy to control, it is easy to appear parallelogram, so the parts and structural parts that need right-angled parts in construction and machinery are replaced by rounded square steel or bars, which not only increases The amount of raw materials is increased, and the subsequent processing time is increased, which indirectly increases the cost of use. Therefore, it is of great practical value to f...
