Problems solved by technology

[0003] The above-mentioned conventional forging schemes all have the problems of large machining allowance and high processing cost. It needs to be processed into a hexagon after the thickness is machined in place, and the machining cost is high, and the processing cycle is long. In terms of cost control and delivery time There are serious deficiencies

Embodiment 1

[0029] against Figure 4 Forging diagram, blanking: 1180kg;

[0030] This batch of forged steel ingots has a head size of 550mm / tail size of 490mm and a length of 556mm square ingot.

[0031] Specifically include the following steps:

[0032] S1: Heat the billet to 1220°C, keep it warm for 3.5 hours, and stretch it to 420mm×420mm square and 850mm long at one time;

[0033] S2: One time upsetting to 600mm×600mm, height 400mm;

[0034] S3: Secondary extension to 420mm×420mm square, 845mm long;

[0035] S4: secondary upsetting to 350 height, outer diameter ∮730;

[0036] S5: After forging the billet, the forging method is rotated according to the angle, and the hexagonal square plate is finished and formed (such as image 3 shown).

[0037] Such as figure 2 As shown, in said S5, the specific forging method includes the following steps:

[0038] A) First, the billet is formed into a cake-shaped forging;

[0039] B) The thickness of the forging is clamped by the manipulat...

Abstract

The invention relate to the field of forging, in particular to a forging method for a hexagonal square plate. The forging method includes the following steps that S1, a billet is heated to 1220 DEG C,the temperature is maintained for 3.5 hours, and primary drawing-out is carried out till a 420mm*420mm square billet with the length being 850 mm is obtained; S2, primary upsetting is carried out till a 600mm*600mm billet with the height being 400 mm is obtained; S3, secondary drawing-out is carried out till a 420mm*420mm square billet with the length being 845 mm is obtained; S4, secondary upsetting is carried out till a billet with the height being 350 mm and the outer diameter being 730 mm is obtained; and S5, after the billet is forged, the forging method is performed by rotating the billet according to an angle, so that the hexagonal square plate is formed through finishing. The forging method has the advantages that cost is lowered, market competitiveness is improved, production efficiency is improved, machining cost is lowered, and the machining period is shortened.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a forging method for a hexagonal square plate. Background technique [0002] In the prior art, the conventional forging scheme of the hexagonal square plate is as follows figure 1 As shown, forged circular forgings are usually used, and then machined according to the drawing size. [0003] The above-mentioned conventional forging schemes all have the problems of large machining allowance and high processing cost. It needs to be processed into a hexagon after the thickness is machined in place, and the machining cost is high, and the processing cycle is long. In terms of cost control and delivery time There are serious deficiencies. [0004] It is urgent to design a more effective forging process for this kind of products. Contents of the invention [0005] The technical problems to be solved by the invention are as follows: firstly, to reduce costs and improve market competi...
