Embodiment Construction

[0014] For the molding method of L-ring products, see figure 1 , figure 2 , the specific process is as follows: blanking - upsetting - drawing and lengthening - blanking - pre-forming - horse frame reaming + trimming and forming, the specific steps are as follows: loading and unloading from raw materials, and then the obtained blanking Carry out upsetting, and then lengthen to obtain the corresponding blank, and then place the blank in the corresponding drain pan for upsetting, punching, and pre-forming. The formed blank has an L-shaped section, and then the L-shaped blank is placed. The reaming correction is carried out on the horse frame to form the designed L-ring products.

[0015] The final molding state of L-ring products is obtained by reaming, in which the diameter of the center hole must be greater than or equal to half the outer diameter of the product to ensure the accuracy of molding;

[0016] The shape of the blank preformed by upsetting and punching through th...

Abstract

The invention provides a forming method of L-shaped ring type products. The forming method of the L-shaped ring type products realizes near-net forming of the L-shaped ring type products by improvingthe blank production technology and performing step chambering so as to realize processing little in cutting or free of cutting and realize heat treatment for rough blanks, thereby realizing the purpose of reducing production cost. The forming method of the L-shaped ring type products includes the steps: performing blanking on raw materials, then preforming upsetting on materials obtained throughthe blanking, then obtaining the corresponding rough blanks through drawing, next placing the rough blanks in corresponding leaking plates for upsetting, punching and preforming, forming blanks with L-shaped sections, and afterwards placing the blanks with the L-shaped sections on a mandrel supporter for performing chambering amendment so as to form the designed L-shaped ring type products.

Description

technical field [0001] The invention relates to the technical field of material heat treatment, in particular to a molding method for L-shaped ring products. Background technique [0002] The existing molding technology is based on experience and experimental data. To formulate a new part molding process, a lot of modification and debugging are often required during production. The development of computer and computing technology, especially the development of computing technology for nonlinear problems, makes the simulation analysis and optimization of the forming process possible. Through a lot of work abroad, a number of commercial software such as casting, forging, cover stamping, and mold CAD / CAM have been formed. It has effectively promoted the development of near-net-shape technology. my country has done a lot of work in simulation analysis and research, but the power is scattered, and the input of each unit is insufficient. There are many individual studies, and few o...
