Embodiment Construction

[0033] The specific implementation of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0034] The invention relates to a forging process of a rectangular forging in the field of forging. Such as Figure 1 to Figure 5 The shown structure of the present invention is a radial forging machine for a rectangular forging, including two pairs of vertically distributed hammerheads, and the side of the rectangular forging includes a wide surface and a narrow surface. It is suitable for the process of rectangular forgings, and realizes forging rectangular forgings with radial forging machines. The billet used for production is No. 45 steel continuous casting billet with a cross-section of 350mm×50mm.

Abstract

The invention discloses a radial forging machine of a rectangular forged piece. The radial forging machine comprises two pairs of hammers distributed vertically, wherein broad surfaces and narrow surfaces are arranged at the side surfaces of the rectangular forged piece; one pair of hammers is concave forging hammers, namely a first forging hammer (1) and a second forging hammer (2); and the other pair of hammers is convex forging hammers, namely a third forging hammer (3) and a fourth forging hammer (4). With the adoption of the technical scheme, the structure and the forging characteristics of the radial forging machine are considered fully, and the down-pressing quantity of each pass is distributed reasonably, so that the product appearance and the core quality after forging are ensured; and the down-pressing quantity of each pass is determined after careful calculation, so that the defects of folds, flaws and the like are overcome.

Description

technical field [0001] The invention belongs to the technical field of thermal pressure processing equipment and technology for metal materials. More particularly, the present invention relates to a radial forging machine for rectangular forgings. Background technique [0002] Solid rectangular forgings are the second type of free forgings, which are generally formed by free forging. The forging process tools are simple, versatile, and flexible, but this type of forming method has low precision and large machining allowances. Production low efficiency. Contents of the invention [0003] The invention provides a radial forging machine for rectangular forgings, the purpose of which is to forge rectangular forgings with higher dimensional accuracy. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: [0005] The radial forging machine for rectangular forgings of the present invention includes two pairs of vertically dist...
