Problems solved by technology

At present, the production technology plan of domestic wedge-shaped plate forgings is to adopt steel ingot→heating, forging→normalizing and annealing, but there are problems such as large forging allowance, long follow-up machining time and serious waste of raw materials, and there is also the problem of producing steel ingots due to double size Heavy weight, high requirements on the press, less deformation of the core during deformation, resulting in poor internal quality and easy damage to the hydraulic system of the jaws, which is a relatively serious problem for equipment

Abstract

The invention discloses a processing method for a wedge-shaped plate forging, which belongs to the technical field of steel forging and forming. The problem to be solved by the present invention is to reduce the production cost of the wedge-shaped plate. The technological process of the present invention is steel ingot heating → jaw pressing → chamfering → bottom removal of ingot → first upsetting → first drawing of rectangular blank → second upsetting → second drawing of rectangular blank → third drawing Rectangular blank→half-die forging with special upper anvil→heat treatment→finishing each part to the finished product size, the special upper anvil is an upper flat anvil, and the angle between the bottom edge of the upper flat anvil and the horizontal plane is less than or equal to the wedge angle of the wedge plate forging. The present invention adopts two upsetting and two drawing forging forming while changing from the traditional round but not square to square forging process breakthrough. The special flat anvil is used for the final fire finishing, and the special tool is used for forging forming to make the wedge-shaped plate forging qualified at one time. The rate reaches more than 95%, the metal fiber streamline is better, the operation is simple, and the weight of the forging blank process is reduced. The invention is used for processing wedge-shaped plate forgings.

Description

technical field [0001] The invention belongs to the technical field of forging and forming of steel materials; in particular, it relates to a processing method of a wedge-shaped plate forging. Background technique [0002] Free forging is a processing method that uses impact force or pressure to cause plastic deformation of metal blanks on the anvil or between the upper and lower anvils of the forging press to obtain forgings. Compared with casting products, free forging can not only eliminate the defects such as shrinkage cavity, porosity, and pores that may be caused by casting products, but also refine the grains to improve the mechanical properties of the product. Free forging relies on manual operation to control the shape and size of the forging, so the precision of the forging is low, the machining allowance is large, the labor intensity is high, and the productivity is not high, so it is mainly used in single piece and small batch production. [0003] Wedge plate, a...
