Problems solved by technology

The quality of forged products is generally higher than that of cast products, but the weight of the hinge beam is heavy and the shape is complex. The existing forging technology level is also to freely forge the outer contour by heating the blank for many times, and the ears are cut and machined. Obtained by other methods, the machining allowance is large, and the material utilization rate is low

preparation example Construction

[0034] A method for preparing a hinged beam of an integral hinged beam closed die forging die, comprising the following steps:

[0035] Step 1: Heating the steel ingot blank to 1150-1200°C and keeping it warm for 15-20 hours to make the internal temperature of the steel ingot blank uniform;

[0036] Step 2: Install the upper die base 4 on the slider 1 of the large-tonnage press, the punch 5 is installed on the bottom of the upper die base 4, the punch pad 11 is installed in the upper die base 4, and the upper die base 4 4 and the punch 5 are equipped with a punch 6, and the die punch is a primary pressing die punch at this time;

[0037] Step 3: Place the steel ingot blank after heat preservation in step 1 in the forming die 2, and use the large-tonnage press and the punch of the primary pressing die described in step 2 to press the steel ingot blank once, so that the forming die 2 The steel ingot blank becomes the hinge beam blank;

[0038] Step 4: Use the hydraulic cylinde...

Abstract

The invention belongs to an integral type hinge beam closed-die forging and pressing forming die and a hinge beam manufacturing method. The integral type hinge beam closed-die forging and pressing forming die comprises a mold punch connected to a pressing machine sliding block, a shaping female mold and an ejection block arranged at the inner bottom of the shaping female mold, wherein the mold punch comprises an upper mold base connected to the pressing machine sliding block, a male mold connected to the upper mold base and a piercing puncher chip arranged in the upper mold base and passing through the male mold; the forming female mold is of a top-to-bottom through hole structure, and the shape of the cavity of the interior of the forming female mold is matched with a hinge beam; and the ejection block is movably arranged at the inner bottom of a through hole of the forming female mold. The integral type hinge beam closed-die forging and pressing forming die has the advantages of one-time heating, closed-die hot extrusion forming, compacted and impregnable four lug parts of a workpiece, guaranteed product quality, small allowance for machining, high utilization rate of materials, high production efficiency and low production cost.

Description

technical field [0001] The invention belongs to the technical field of forging and forming of large forgings, and in particular relates to an integral hinge beam closed die forging forming mold and a preparation method of the hinge beam. Background technique [0002] The six-sided top hydraulic press is the main equipment for the production of superhard materials, and it is also a special equipment for the synthesis of superhard materials. The hinged beam is the core component of the six-sided top hydraulic press. It not only bears the largest force, but also the alignment, synchronization and stability required for high-pressure synthesis are closely related to the processing accuracy and rigidity of the hinged beam. The performance of the hinge beam directly affects the processing quality and overall performance of the six-sided hydraulic press. At present, the hinge beam is basically produced by casting process. Due to the complex shape of the hinge beam, casting defects...
