Forging Mechanism for Continuous Forging Point Rail and Preparation Technology of Forging Point Rail

Abstract

The invention discloses a forging mechanism for continuous forging point rails and a preparation process for forging point rails, comprising: a preheating rail for accommodating the point rails to be forged, the preheating rails can maintain the temperature of the forging point rails during the forging process Hot forging is carried out at a temperature above 800°C, and there is also a forging wheel for forging the point rail to be forged. The way of flange extrusion makes the force-bearing area of ​​the point rail to be forged large, and the force is uniform, continuous extrusion molding, easy to quickly form , the equipment loss is small, and the forging time is reduced. The invention also discloses a preparation process for a forging point rail, which includes the following steps: S1: heat treatment; S2: forging; S3: shaping; S4: unloading; S5: cooling; S6: Straightening; S7: Grinding. The invention can forge V-shaped, curved, straight forging materials, one end is bent and the other end is straight, and has a wide range of applications.

Description

technical field [0001] The invention relates to the technical field of forging equipment, in particular to a forging mechanism for continuous forging point rails and a preparation process for forging point rails. Background technique [0002] Because the austenite transformation temperature of steel is about 960 degrees, and the characteristics of austenite are relatively soft, so it is easy to deform and process. If it is directly forged without heating, it will cause the lattice distortion of the material, generate internal stress, and even crack. After high-temperature forging in the austenitic state, the crystal lattice will be reorganized to reduce the generation of internal stress. [0003] Forging can be divided into hot forging, warm forging and cold forging according to the forging temperature. During hot forging, the temperature is kept above 900°C. During hot forging, the forging is easy to form, and the internal stress is reduced, so the quality of the forging i...

AI Technical Summary

Problems solved by technology

[0005] 1. The temperature of the forging is cooled quickly, it is not easy to maintain hot forging, and the internal stress of the forging increases during forging, which reduces the quality of the forging;

[0006] 2. The existing forging equipment sets the shape after the forging material is forged. On the one hand, it increases the cost. On the other hand, the temperature of the forging material decreases and it is difficult to set the shape. Cold forming is easy to cause a large internal stress in the forging material and reduce the strength of the forging material And the corresponding performance, the bending of the forging needs to be processed later, which increases the corresponding production cost and production process;

[0007] 3. The number of times of beating by impact hammer is usually more than a thousand times, the number of times of beating is large, the equipment loss is large, the contact surface is small, the force on the surface of the forging material is uneven, and the beating is time-consuming, which reduces the efficiency of forging material forging
