Description

Technical Field

[0001] This utility model relates to the technical field of rail vehicles and key components, and in particular to a bolt hot upsetting device. Background Technology

[0002] To ensure that the overall production capacity of high-speed trains can meet the ever-increasing demands, ordinary hot upsetting equipment is no longer sufficient. To improve product efficiency and quality through process and tooling improvements, a specialized processing tooling is needed to meet the quality and delivery requirements.

[0003] The known defects and problems of hexagonal head hot upsetting equipment technology are as follows:

[0004] 1. Conventional integral mold structures are difficult to adapt to complex bolt head shapes (such as hexagonal heads, flange faces, etc.), requiring multiple processing steps and resulting in low efficiency;

[0005] 2. There is no dephosphorization device, and the oxide scale is severe;

[0006] 3. The demolding mechanism is mostly of the ordinary ejector pin type, which is prone to friction with high-temperature workpieces, accelerating the wear of the ejector pin;

[0007] 4. During the thermoforming of materials, due to different cavity dimensions, bolts may be bent, hexagonal heads may have excessive burrs or be incomplete, and mold jamming may also occur.

[0008] 5. The hydraulic / drive sliding is slow, which affects the temperature during hot forging.

[0009] Therefore, we propose a bolt hot upsetting device to solve the problems mentioned above. Utility Model Content
