Embodiment Construction

[0048] 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.

[0049] Such as figure 1 The expressed structure of the present invention is a feeding position before forging applied to the production process of forging a rectangular section billet into a round billet. The equipment used in the forging production process includes two pairs of forging hammers arranged perpendicular to each other, wherein one pair is No. 1 hammer 1 and No. 2 hammer 2 , and the other pair is No. 3 hammer 3 and No. 4 hammer 4 .

[0050] Different from the common square billet forging round billet and round billet forging round billet, the present invention aims at forging a rectangular billet into a round billet. T...

Abstract

The invention discloses a forging and striking production process for a blank with a rectangular section. Equipment adopted in the striking and forging production process comprises two pairs of forging hammers which are mutually vertically distributed, wherein one pair of forging hammers include a first hammer and a second hammer, and the other pair of forging hammers include a third hammer and a fourth hammer; and the section of the blank is forged and struck for seven passes to become rectangular, approximately square, octagonal until circular. Due to the adoption of the technical scheme, a process for forging and striking the blank with the rectangular section to form a circular blank is precisely obtained through simple and effective derivation of equations by utilizing the forging characteristics of a radial forging machine; the forging and striking production process accords with a common forging and striking deformation process, the regularity of the shape of a forged product is ensured through a reasonable deformation step; and each pass reduction is determined through careful calculation, therefore, the quality of the forged blank is ensured, and defects such as folding, cracks and the like are prevented from being caused.

Description

technical field [0001] The invention belongs to the technical field of metallurgical industrial production, and relates to a forging process technology of a radial forging machine. More specifically, the invention relates to a forging production process of a rectangular cross-section billet. Background technique [0002] The common round billet forging process is to use a square billet to make a round billet, or use a round billet to make a round billet. [0003] For billets with a rectangular cross-section, the general production process should be to punch the rectangular billet into a square billet first, then chamfer, round and finally shape it. But the width of the anvil surface of the anvil of the forging machine is not enough, and this method cannot be realized. [0004] Since the rectangular cross-section blank is different from the rotary parts such as the square billet and the round billet, it cannot be produced according to the conventional forging procedure.
